The upper frame (11) and the lower frame (12) are arranged in parallel and symmetrically, and each is assembled from at least three aluminum section bars. The adjacent two aluminum section bars are fixed by fasteners (20). The upper end of each side plate (13) is clamped in the clamping groove of the aluminum section bar of the upper frame (11), and the lower end is clamped in the clamping groove of the aluminum section bar of the lower frame (12) corresponding to the aluminum section bar of the upper frame (11). The top end and the bottom end of the side wall of the door plate (14) are hingedly connected with the aluminum section bars of the upper frame (11) and the lower frame (12), respectively. The top section bar (15) is clamped in the clamping groove of the aluminum section bar of the upper frame (11).

The stress on the section bar is uneven, and the stability is poor. When multiple vertical beams are connected under the same top section bar, "L"-shaped corner pieces need to be arranged on both sides of each vertical beam to ensure the uniform stress on the section bar, and the probability of failure of the bolt is higher.

[0008] Further setting of the utility model: the top profile includes a partition plate above the guide strip, the mounting hole penetrates the partition plate and communicates the upper portion of the partition plate and the lower portion of the guide strip, when the vertical profile is locked with the top profile, the head of the bolt abuts against the partition plate.

[0009] By means of the further setting, the partition plate can be used for supporting the head of the bolt, controlling the size of the threaded cooperation of the bolt in the threaded hole, increasing the distance between the abutting position of the bolt head and the bottom of the guide strip, reducing the distance between the top end of the top profile and the abutting position of the bolt head, further reducing the stress moment of the top profile, further preventing the overturning deformation of the top profile and the vertical profile, and enhancing the connection stability.

[0010] Further setting of the utility model: the top profile further comprises a matching plate above the partition plate, a gap not less than the height of the bolt head exists between the matching plate and the partition plate, an avoiding hole is formed in the matching plate and located directly above the mounting hole, and the avoiding hole can be used for the bolt to pass through.

[0012] Further setting of the utility model: two recesses are formed by the downward recesses on the two sides of the matching plate.

[0013] By means of the further setting, the two recesses can be used as tracks for positioning and installing the remaining devices such as the lamp strip, and the recess portions of the two top profiles can share the same profile for building and realizing preliminary positioning and splicing.

[0014] Further setting of the utility model: a hollow region is arranged in the top profile, and the top profile comprises a support arranged in the hollow region and used for supporting.

[0015] By means of the further setting, the hollow region can make the top profile lightweight and lower in material cost, and the support is used for stably supporting the structure of the top profile and preventing the top profile from deforming under stress. BRIEF DESCRIPTION OF DRAWINGS
