[0029] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] The utility model provides a technical solution, referring to Figure 1-Figure 5 A structure for facilitating installation of a lamp includes a peripheral member 1 and a lamp housing 2. In the embodiment of the present application, three lamp housings 2 are installed on each peripheral member 1. Three mounting grooves 12 are provided on the peripheral member 1, and each lamp housing 2 is correspondingly installed in one mounting groove 12.

[0032] Each installation groove 12 has a bottom wall with an anti-mistake hole 11, and each lamp housing 2 is fixed with an anti-mistake column 21 for plugging into the anti-mistake hole 11. The anti-mistake hole 11 is in the shape of a long strip, and the three anti-mistake holes 11 on the peripheral member 1 are arranged at different angles. The anti-mistake column 21 includes a base 211 and a long strip 212. The cross section of the base 211 is circular or regular polygonal, and the long strip 212 is used to be plugged into the anti-mistake hole 11.

[0033] The anti-error columns 21 on each lamp housing 2 are set at different angles, and the rotation angle of the anti-error columns 21 on each lamp housing 2 is the same as the rotation angle of the corresponding anti-error holes 11, so that the correct lamp housing 2 can only be installed in the corresponding anti-error holes 11, thereby reducing the occurrence of installation errors of the lamp housing 2.

[0034] Each mounting groove 12 is also provided with a mounting hole 13 on the bottom wall, and a stopper 3 for being inserted into the mounting hole 13 is fixed on the lamp housing 2. When the lamp housing 2 is installed in the mounting groove 12, the stopper 3 is inserted into the mounting hole 13. The stopper 3 includes a central column 31 and a plurality of deformation plates 32 fixed to the peripheral side of the central column 31, and one end of the deformation plate 32 is fixed to the end of the central column 31 away from the lamp housing 2; the plate surface of the deformation plate 32 is spaced apart from the side wall of the central column 31, and the free end of the deformation plate 32 can be deformed in a direction close to the central column 31. In addition, when the limiting member 3 is in a normal state, the outermost diameter of the limiting member 3 is larger than the maximum aperture of the mounting hole 13. Therefore, when the lamp housing 2 is installed in the mounting groove 12, the deformable plate 32 first abuts against the side wall of the mounting hole 13. Under the restriction of the mounting hole 13, the deformable plate 32 deforms toward the direction close to the center column 31, so that the limiting member 3 can pass through the mounting hole 13. After passing through, the deformable plate 32 returns to its original shape under the action of elasticity, and the end face of the deformable plate 32 abuts against the bottom wall of the mounting groove 12, so that the lamp housing 2 and the peripheral member 1 are not easily separated.

[0035] The side wall of the mounting hole 13 is recessed inward to form a plurality of limit grooves 14, and the plurality of limit grooves 14 are arranged corresponding to each deformation plate 32. In addition, an anti-displacement block 33 is arranged on the side wall of the deformation plate 32 close to the center column 31. When the shell is installed into the mounting groove 12, the displacement block is inserted into the limit groove 14. The anti-displacement block 33 can limit the relative rotation of the lamp housing 2 and the peripheral component 1, thereby making the installation between the lamp housing 2 and the peripheral component 1 more stable.

[0036] A accommodating cavity 311 is provided in the central column 31, and a storage rope 34 is fixed to the side wall of each deformation plate 32 facing the central column 31, and the free end of the storage rope 34 extends from the side wall of the central column 31 into the accommodating cavity 311, and the accommodating cavity 311 passes through the end surface of the central column 31 away from the deformation plate 32, and a pull ring 4 is provided at this end of the central column 31, and the free end of each storage rope 34 passes through the accommodating cavity 311 and is connected and fixed to the pull ring 4.

[0037] When the limiting member 3 is in a natural state, the pull ring 4 is pressed against the end face of the central column 31; when the lamp housing 2 and the peripheral member 1 need to be disassembled, the pull ring 4 can be pulled to tighten the storage rope 34, so that the deformation plate 32 can move toward the direction close to the central column 31, and then the limiting member 3 can pass through the mounting hole 13, and the lamp housing 2 and the peripheral member 1 are separated to achieve disassembly, which is simple and convenient to operate.

[0038] Furthermore, the mounting groove 12 includes a base portion 121 arranged close to the bottom wall and an enlarged portion 122 close to the notch of the mounting groove 12. An extension ring 22 is fixed to the periphery of the side of the lamp housing 2 away from the limiting member 3. When the lamp housing 2 is installed in the mounting groove 12, the extension ring 22 is located in the enlarged portion 122, and a water blocking ring 5 is clamped between the extension ring 22 and the enlarged portion 122. The water blocking ring 5 is specifically a rubber waterproof ring.

[0039] An annular groove 51 is formed on the inner wall of the water blocking ring 5, and an annular rib 23 is integrally formed on the outer side of the outer ring 22. When the water blocking ring 5 is sleeved on the outer ring 22, the annular rib 23 is inserted into the annular groove 51, so that the water blocking ring 5 is not easily separated from the outer ring 22; at the same time, by providing the water blocking ring 5, when the lamp housing 2 is installed to the peripheral component 1, the water blocking ring 5 can increase the friction force and installation compactness between the lamp housing 2 and the peripheral component 1, thereby making the lamp housing 2 more securely installed.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
