Description

Technical Field

[0001] The utility model relates to a splicing type lamp housing structure. Background Art

[0002] In the prior art, such as the Chinese utility model patent document with the publication number CN219014161 U, a frameless flat lamp is disclosed, which includes a lamp body with a light source cavity. A light-transmitting diffusion plate is arranged at the opening of the light source cavity. The inner wall of the light source cavity is inclined away from the light source cavity. A stepped boss is integrally formed at the edge of the inner wall of the light source cavity. A positioning convex edge is integrally formed at the edge of the lamp body. A butting body is also arranged at the edge of the lamp body. The cross-section of the butting body is an inverted V shape. The light-transmitting diffusion plate is attached to the butting body and fixed by ultraviolet fixing glue. The cross-section of the butting body is an inverted V shape. Convex points are arranged on the inner wall of the butting body and a buckling piece is arranged in the middle of the concave area of the butting body. The edge of the lamp body is sleeved into the concave area of the butting body and positioned by the convex points and the buckling piece.

[0003] Based on the above, in the prior art, the existing lamp housing structure is a housing with an open lower end. This kind of lamp housing with a closed upper end is made by stretching aluminum materials with a mold. The disadvantages of using a mold to stretch and manufacture the lamp housing are that the mold manufacturing cost is high and a set of molds can only produce lamp housings of one specification, with poor versatility, and further improvement is needed. Content of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a splicing type lamp housing structure.

[0005] A splicing type lamp housing structure designed according to this purpose includes an annular housing. A back plate is installed on the upper part of the annular housing, and a light-transmitting plate is installed on the lower part of the annular housing. The annular housing is composed of at least three sequentially connected profiles.

[0006] Preferably, two adjacent profiles are fixed by laser welding.

[0007] Preferably, a plug-in groove is arranged on the inner wall surface of the upper part of the profile, and the side edge of the back plate is plugged into the plug-in groove.

[0008] Preferably, an L-shaped bending part is arranged at the lower part of the profile. The L-shaped bending part forms an installation groove with an open lower side, and the side edge of the light-transmitting plate is fixed in the installation groove.

[0009] Preferably, the light-transmitting plate is fixed in the installation groove by gluing.

[0010] Preferably, a buckle is arranged on the profile for clamping with the ceiling keel.

[0011] Preferably, the profile and the buckle are of an integral structure.

[0012] Preferably, the annular housing is composed of four profiles connected in sequence to form a quadrilateral annular housing.

[0013] Preferably, the annular housing is composed of five profiles connected in sequence to form a pentagonal annular housing.

[0014] Preferably, the annular housing is composed of eight profiles connected in sequence to form an octagonal annular housing.

[0015] Compared with the prior art, the annular housing of the present utility model is at least composed of three profiles connected in sequence. The annular housing composed of spliced profiles of the present utility model is then combined with a back plate and a light-transmitting plate to form a complete lamp housing. The annular housing composed of spliced profiles can cut the profiles according to different product shapes and sizes to realize splicing the profiles according to different product specifications, which not only saves the mold opening cost but also has good versatility.
