[0018] It should be noted that in order to avoid blurring the present disclosure due to unnecessary details, only the structure and/or processing steps closely related to the object of the present disclosure are shown in the accompanying drawings, and other details that are not closely related to the present disclosure are omitted.

[0019] In addition, it should be noted that the terms “comprise”, “comprising”, “include”, “including”, or any other variant are intended to encompass non exclusive inclusion, such that a process, a method, an item, or a device that includes a series of elements not only includes those elements, but also other elements that are not explicitly listed, or also include elements inherent to such a process, a method, an item, or a device.

[0020] As shown in FIG. 1 to FIG. 7, the present disclosure discloses a ceiling lamp 100, the ceiling lamp 100 is provided with a quick connection structure 10 for mounting on a mounting surface. The quick connection structure 10 can connect different lamps to meet the different requirements of users, and there is no limitation here. For clarity, the following section of the specification will provide a detailed illustration of the specific structure of the ceiling lamp 100.

[0021] As shown in FIG. 1, the ceiling lamp 100 includes a quick connection structure 10 and a lamp body 20. The quick connection structure 10 is in a circular shape, and one side of the quick connection structure 10 is fixed on a mounting surface, the other side of the quick connection structure 10 is configured to install the lamp body 20. The quick connection structure 10 is provided with a connector 11 that is radially arranged, the connector 11 is configured to be connected with an inner side of the quick connection structure 10 to enhance the strength of the quick connection structure 10, and a gap is reserved on two sides of the connector 11 for the lamp body 20 to dissipate heat. The width of the connector 11 can be set as needed, which is not limited herein.

[0022] The connector 11 is provided with a wiring terminal 12, the wiring terminal 12 has a first end facing the mounting surface and a second end facing the lamp body 20. The first end and the second end are electrically conductive, and the first end of the wiring terminal 12 is configured to be connected with a wire of the mounting surface, and the second end of the wiring terminal 12 is configured to be connected with a wire of a connection port 21 of the lamp body 20 (not shown). It can be understood that the second end of the wiring terminal 12 can be detachably connected to the connection port 21 of the lamp body 20 for easy installation and disassembly. The second end of the wiring terminal 12 includes but is not limited to a press type structure or a locking type structure. It can be understood that during the installation process of the ceiling lamp 100, only the quick connection structure 10 needs to be pre-installed and the wire of the installation surface needs to be connected to quickly install the lamp body 20.

[0023] As shown in FIG. 2 and FIG. 3, in another example of the present disclosure, the wiring terminal 12′ and the connection port 21′ can also be electrically connected using the structure of an electrical connector. In this way, there is no need to set a wire between the wiring terminal 12′ and the connection port 21′, which is not limited herein, as long as it is easy to install and disassemble.

[0024] Specifically, an edge of the quick connection structure 10 is formed with a first annular wall 13 extending towards the lamp body 20, and the lamp body 20 is provided with a second annular wall 22 extending towards the quick connection structure 10. The first annular wall 13 is opposite to the second annular wall 22, and the second annular wall 22 is located on an inner side of the first annular wall 13, that is, the quick connection structure 10 covers an outer side of the second annular wall 22.

[0025] In another example of the present disclosure, the first annular wall 13 and the second annular wall 22 can be tightly combined to prevent loosening, which can be set as needed, which is not limited herein. In other examples of the present disclosure, there may be a mutually matched threaded structure between the first annular wall 13 and the second annular wall 22 to enable the lamp body 20 to be securely connected to the quick connection structure 10 through rotation, which is not limited herein.

[0026] As shown in FIG. 6 and FIG. 7, preferably, the lamp body 20 includes a lampshell 24 and a lampshade 25, the lamp lampshell 24 is sealed and assembled with the lampshade 25, so that the lamp body 20 can achieve integrated sealing, and therefore users only need to assemble the lamp body 20 with the quick connection structure 10.

[0027] As shown in FIG. 4, further, the quick connection structure 10 is provided with a first limiting member 14, the first limiting member 14 includes a bearing portion 141 and a stop portion 142, and the bearing portion 141 and the stop portion 142 are enclosed to form an accommodating chamber 143, the accommodating chamber 143 is provided with an opening that is horizontally oriented, the opening and the stop portion 142 are respectively located on both sides of the bearing portion 141. The inner wall of the second annular wall 22 is provided with a second limiting member 23 for cooperating with the first limiting member 14. The second limiting member 23 includes but is not limited to a block shape or a strip shape, and the second limiting member 23 can enter the accommodating chamber 143 from the opening to be accommodated in the accommodating chamber 143. The bearing portion 141 is configured to carry the second limiting member 23, that is, carry the weight of the lamp body 20, and the stop portion 142 is configured to prevent the second limiting member 23 from excessive rotation. In a case that the quick connection structure 10 covers the outer side of the second annular wall 22, the first limiting member 14 and the second limiting member 23 are driven to cooperate with each other by rotating the lamp body 20, to install the lamp body 20 on the quick connection structure 10. In other examples of the present disclosure, reinforcing ribs may be provided on the side edges of the bearing portion 141 and the stop portion 142, or the bearing portion 141 and the stop portion 142 may be integrally formed or embedded in the quick connection structure 10, which is not limited herein.

[0028] As an example of the present disclosure, the bearing portion 141 is not horizontally arranged, that is, the bearing portion 141 is higher at the opening and lower at the stop portion 142, in this way, the second limiting member 23 has a tendency to move towards the stop portion 142 in the accommodating chamber 143 under the action of gravity, to prevent accidental detachment of the lamp body 20.

[0029] As shown in FIG. 4 and FIG. 5, specifically, an annular groove 15 is formed between the first annular wall 13 and the first limiting member 14 for the rotation of the second annular wall 22. As the second limiting member 23 is connected to the inner wall of the second annular wall 22, a corresponding sliding groove (not shown) for the sliding of the second limiting member 23 can be opened on the side of the accommodating chamber 143 facing the first annular wall 13, and the sliding groove is connected to the opening.

[0030] The annular groove 15 extends towards a radial direction of the quick connection structure 10 to form an installation portion 16, the installation portion 16 is provided with an installation hole 161 and an installation member (not shown). The installation member passes through the installation hole 161 to install the quick connection structure 10 on the mounting surface. The installation hole 161 and the installation member include but are not limited to a bolt and a screw hole, and the installation portion 16 is arranged close to the stop portion 142.

[0031] In an example of the present disclosure, at least two first limiting members 14 are provided, preferably, four first limiting members 14 are provided, and the four first limiting members 14 are uniformly distributed on the quick connection structure 10. Correspondingly, four second limiting members 23 and four installation portions 16 are provided, thereby enhancing the bearing capacity of the bearing portion 141 on the lamp body 20 and enhancing the stability of the structure. It can be understood that the larger the contact area between the first limiting member 14 and the second limiting member 23, the more stable the connection between the lamp body 20 and the quick connection structure 10. Specific arrangements can be made as needed, which is not limited herein.

[0032] As shown in FIG. 5, in an example of the present disclosure, the second limiting member 23 is provided with a stop rib 231 that is protruding, and a stop groove 144 is correspondingly provided in the accommodating chamber 143 to accommodate the stop rib 231. In a case that the second limiting member 23 enters the accommodating chamber 143 from the opening, the stop rib 231 slides into the stop groove 144 to fix the relative position of the lamp body 20 relative to the quick connection structure 10. Specifically, the stop rib 231 may be provided at the lower end of the second limiting member 23, and the stop groove 144 may be provided on the bearing portion 141. In other examples of the present disclosure, the stop rib 231 and the stop groove 144 may also be provided on the side or above of the second limiting member 23. Of course, it can be understood that the stop groove 144 may be provided on the second limiting member 23, and the stop rib 231 may be provided in the accommodating chamber 143. The specific connection structure between the second limiting member 23 and the accommodating chamber 143 includes but is not limited to an elastic structure, as long as it is easy to install and disassemble, which is not limited herein.

[0033] Preferably, a guiding inclined surface 145 is provided on the second limiting member 23, the guiding inclined surface 145 is oriented towards the opening to insert the second limiting member 23 into the accommodating chamber 143 from the opening. In this case, the guiding inclined surface 145 can be used to indicate the correct installation direction and prevent incorrect installation.

[0034] The quick connection structure 10 is provided with a through hole 17 that communicates with the accommodating chamber 143. The through hole 17 can be used for heat dissipation of the lamp body 20, while reducing the frictional force between the upper end of the second limiting member 23 and the corresponding position of the lower end of the quick connection structure 10.

[0035] In summary, the quick connection structure 10 provided by the present disclosure can provide an installation platform for different lamps, which is convenient for installation and disassembly.
