Description

Parallel type electric box door control device

The invention is a parallel-type electric box door control device, in particular, the opening and closing of the power box box door is used to control the rotation of a connecting rod at an angle, thereby controlling whether the other box box door parallel to the power box can be opened, to achieve After the power box door is opened and the power is turned off, the other box door can be opened to avoid the safety maintenance of electric shock, and the connection angle is used to control whether the other box door can be opened by the rotation angle method. Controlled by lateral displacement, it has the advantage of high control accuracy.

Press, the electrical boxes are connected in parallel, as shown in Figures 1 and 2, generally have a power box 1 and other boxes 2 (such as power distribution box, can be connected in parallel). The power supply box 1 is the main power supply source of the parallel electrical box. The power supply is redistributed to other box 2 applications, and its power supply is high-voltage. During maintenance, if the power supply is not turned off, open the other box 2 during construction. It is easy to get an electric shock if the operation is not careful. Therefore, in order to prevent the above-mentioned loss, the design of the mechanism is designed so that when the door 10 of the power box 1 is opened, the door 10 of the power box 1 will simultaneously unhook the main power switch in the power box 1 to make the power supply Box 1 is powered off. In design, the door 10 of the power box 1 is required to be opened first, and the door 20 of the other box 2 can be opened, to avoid that the door of the other box 2 can be opened at any time when the main power switch is not closed, and there is a problem of electric shock.

The control method of the above conventional box door (such as the German Rittal manufacturer), as shown in FIG. 1, is provided with a connecting rod 3 in the box of the electric box. When the box door 10 of the power box 1 is closed, the connecting rod 3 can be Pushed by the box door 10 and laterally displaced by a predetermined distance, so that the locking member 31 located on the link 3 and being laterally displaced in synchronization with the link 3 is locked with the locked member 32 located on the box door 20 of the other box 2 Live fixed, can not be opened arbitrarily (see Figure 2). When the door 10 of the power box 1 is opened, the connecting rod 3 is pushed back to the original position laterally by the spring, and the positions of the catching member 31 and the catching member 32 are staggered left and right (as shown in FIG. 1). The door 20 of the other box 2 begins It can be opened, so that the door 10 of the power box 1 is opened, and the door 20 of the other box 2 can be opened.

This practice controls the way in which the door 20 of the other box 2 is stuck, and has the following deficiencies in application:

1. The connecting rod 3 controls the jamming of the door 20 of the other box 2 in the lateral displacement mode, and the alignment accuracy between the clamping member 31 and the stuck member 32 is very high, otherwise it is easy to cause the connecting rod 3 The displacement stroke error caused the above-mentioned situation of the connection control box door.

2. When the door 10 of the power box 1 is closed, the connecting rod 3 is driven by the door 10 of the power box 1 and the lateral compression spring is displaced; when the door 10 of the power box 1 is opened, the connecting rod 3 is restored by the spring Push back to its original position. However, after being used for a period of time, the spring is prone to elastic fatigue, causing the lateral displacement point of the connecting rod 3 to slip to less than the preset position, resulting in control misalignment.

In view of the conventional parallel-type electrical box door control device, the present inventor has the above-mentioned defects in application, and the design is improved, so the present invention has been produced.
