Description

Technical Field

[0001] The invention relates to the field of power distribution boxes, and in particular to a positioning structure of a box door opening power-off device. Background Art

[0002] like Figure 1 As shown, when installing the door-opening power-off device in the electric box or the distribution cabinet, the circuit breaker is installed on the distribution board of the electric box or the distribution cabinet, the distribution board is installed in the box of the electric box or the distribution cabinet, the rotating rod is installed on the circuit breaker, and the external operating structure is installed on the box door of the electric box or the distribution cabinet. It is required that the rotating rod should be inserted into the installation hole of the external operating structure every time the door is closed, because the operating structure and the circuit breaker are not on the same plane, the circuit breaker is set in the electric box, the installation hole of the circuit breaker is a long and deep hole, and the movable range of the installation fastening screw is small. As long as the hole deviates slightly, the rotating rod cannot be aligned with the installation hole of the external operating structure;

[0003] Therefore, the existing installation method of the electric box or distribution cabinet is to install and wire other components on the distribution board first, reserve the installation position of the circuit breaker, assemble and tighten the distribution board and the electric box, and finally install the circuit breaker. When installing the circuit breaker, it is necessary to first open the circuit breaker installation hole. The existing method of opening the circuit breaker installation hole is:

[0004] For small electric boxes or small distribution cabinets: first lay down the small electric box or small distribution cabinet, place the circuit breaker in the approximate position, close the box door, and the rotating rod is visible at the installation hole of the external control structure of the box door. According to the visible position of the rotating rod, open the box door and move the circuit breaker until the rotating rod is moved to the middle of the installation hole. Open the box door, mark the installation hole of the circuit breaker, then open the installation hole of the circuit breaker, install the circuit breaker, and finally install the external control structure;

[0005] For large electrical boxes or large distribution cabinets, large electrical boxes or large distribution cabinets cannot be laid down, and the installation is more troublesome. Someone is required to hold the circuit breaker inside, and someone is required to check the position of the rotating rod outside, move the circuit breaker position until the rotating rod is in the middle of the installation hole of the external operating structure, mark the position, and then open the circuit breaker installation hole. For large electrical boxes or large distribution cabinets, the installation requires two people to complete.
