a fixed structure

Abstract

The invention discloses a fixing structure, which comprises at least two fastening sleeves, a plate body bracket and fasteners, the fastening sleeve is a frame with one side open, and the fastening sleeve is used to be sleeved on the periphery of a box body. The board bracket is clamped between the box body and the fastening sleeve, the fasteners lock the two ends of the opening, the board bracket is provided with lugs, and the lugs are used to fix on the object to be fixed. Adopting a fixing structure of the present invention improves the fixing strength between the board bracket and the box body, reduces the probability of box deformation; solves the problem of dustproof and waterproof, and reaches the IP68 industrial protection level; the gap between the fastening sleeve and the box body Anti-slip parts are also provided to prevent the surface paint of the box body from being scratched by the fastening sleeve, and enhance the anti-slip and anti-shock performance of the fastening sleeve and the box body; in addition, additional technical effects are produced, that is, the surface of the box body can be painted and then assembled. Bracket, enhanced corrosion resistance. If the board bracket is damaged, the board bracket can also be replaced separately without affecting the cabinet.

Description

technical field [0001] The invention relates to the lighting field, in particular to a fixing structure. Background technique [0002] The existing fixing structure of the rectifier box is as follows: the inner wall of the rectifier box is provided with a baffle, the outer wall is provided with fixing ears, and the rivets successively fix the baffle, the rectifier box and one end of the fixing ear. Then fix the other end of the fixing ear on the object to be fixed, so as to fix the rectifier box on the object to be fixed. [0003] The disadvantages of adopting the above technical solution are: the contact area between the fixed ear and the rectifier box is small, and when the fixed ear is stressed, the box is easily deformed, and it is difficult to enhance the fixing strength of the rectifier box; there are holes in the rectifier box, and it is difficult to achieve IP68 industrial protection Level, that is, completely prevent the intrusion of foreign objects and dust, and p...

Problems solved by technology

[0003] The disadvantages of adopting the above technical solution are: the contact area between the fixed ear and the rectifier box is small, and when the fixed ear is stressed, the box is easily deformed, and it is difficult to enhance the fixing strength of the rectifier box; there are holes in the rectifier box, and it is difficult to achieve IP68 industrial protection Level, that is, completely prevent the intrusion of foreign objects and dust, and prevent the intrusion of water when submerged, which reduces the IP protection level of the rectifier; after the box is riveted, it is painted, and before painting, the contact surface between the fixed ear and the box is unprotected , the contact surface is easy to rust, and the corrosion resistance of the box is poor

[0004] Although there are other fixing structures for the rectifier box in the prior art, it is difficult to avoid reducing the IP protection level of the rectifier box, or reducing the fixing strength of the rectifier box, or reducing the IP protection level and fixing strength of the rectifier box at the same time

The analysis of the existing technology shows that it is difficult to avoid reducing the IP protection level and fixing strength of the rectifier box at the same time
