Description

Technical Field

[0001] The utility model relates to the field of electrical boxes, in particular to a novel electrical box connecting frame. Background Art

[0002] The existing patent (Announcement No.: CN209073718U) proposes a building electrical box connection frame, including a support plate, a first support rod, an oblique support rod, a fixed rod, a second fixed rod, a second support rod, a second oblique support rod, a fixing device, a level bubble and an anti-skid pad. The utility model provides a building electrical box connection frame. The design proposes a fixing device design to solve the problem that the support plate surface is smooth and the rubber pad is easy to fall off and the installer is prone to slipping. The anti-skid pad and the support plate are clamped on the inner side of the clamp through the clamp, and the upper and lower end bolts of the clamp are connected and fixed with the threaded rod, so that the clamp is tightly clamped on the surface of the rubber pad. However, its "support plate" is relatively fixed to the supporting structure of the electrical box. When the electrical box is installed in a narrow space, it cannot be displaced without disassembling the electrical box. The structural flexibility is poor and the maintenance needs of the electrical box in a narrow space cannot be met, which has disadvantages. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a new electrical box connecting frame with a stable support and flexible structure, and the longitudinal relative position between the electrical box and the supporting frame can be changed according to the actual installation environment of the electrical box. When the installation environment of the electrical box is relatively narrow, the electrical box can be driven outward to expand the space for disassembly, assembly and maintenance operations, thereby reducing the difficulty of disassembly and assembly of the electrical box and improving the efficiency of electrical box maintenance operations.

[0004] The purpose of this utility model is achieved through the following technical solutions:
