Second lug 8 is installed on second pivot 10 symmetrically, through rotating second pivot 10, makes second lug 8 jack-up first connecting rod 3, first connecting rod 3 one serves first lug 7 and promotes first connecting rod 3 and use the third connecting rod as the rotation of center, fixture block 9 on the second connecting rod 4 will be close to and the card is gone into in the draw-in groove, with right first pivot 17 and cabinet door 2's position is injectd, makes things convenient for the technical staff to open cabinet door 2 to clean and maintain the electric component in the electric switch cabinet.

The first bolt spring is always in a compressed state, and the elastic force of the first bolt spring can enable the first connecting rod 3 to always keep a trend of moving towards the second rotating shaft 10. The second connecting rod 4 is rotatably connected with the side wall of the inner cavity 13 through a third rotating shaft, and in the process that the second connecting rod 4 is pushed by the first bump 7, one end, close to the first connecting rod 3, of the second connecting rod 4 always keeps a certain distance from the first connecting rod 3, so that the normal rotation of the second connecting rod 4 can be ensured.

When the clamping block 9 is clamped in the clamping groove, the second spiral spring 6 is in a stretching state, and one end of the second connecting rod 4 close to the first connecting rod 3 is kept in contact with the first bump 7. So, when rotating second pivot 10, make second lug 8 with first connecting rod 3 breaks away from, the one end and the fixture block 9 that first connecting rod 3 was kept away from to second connecting rod 4 can be under the second spring elastic force effect, and the direction that moves away from first pivot 17 is toward, and then makes fixture block 9 break away from the draw-in groove. That is to say, by rotating the second rotating shaft 10, the latch 9 can be disengaged from the slot or the latch 9 can be latched into the slot, so as to open the cabinet door 2 or limit the angular position of the cabinet door 2.

In one embodiment, as shown in fig. 1 and fig. 2, the electrical switch cabinet further includes a lock 14 installed in a side wall of the inner cavity 13 away from the cabinet door 2, and a key matched with the lock 14, the lock 14 is a pin tumbler lock 14 and includes an inner lock cylinder 15, and one end of the second rotating shaft 10 is fixedly connected with the inner lock cylinder 15.

The cabinet door 2 can be closed by using a key and the spring lock 14, so that a non-technician is prevented from opening the electrical switch cabinet at will, and the safety performance of the electrical switch cabinet is improved. The spring lock 14 is arranged on the side wall of the cavity far away from the cabinet door 2, has smart and simple structure and can well lock the angle position of the cabinet door 2.

In one embodiment, as shown in fig. 2, the electrical switchgear further comprises rolling posts 16, the rolling posts 16 being mounted in the inner cavity 13 and located on both sides of the first link 3. The rolling columns 16 can be arranged in multiple groups, and when the second connecting rod 4 moves up and down, the rolling columns 16 can rotate relative to the second connecting rod 4. The rolling column 16 is arranged to define the position of the second link 4, so that the second link 4 can only move in the vertical direction. Therefore, when the second connecting rod 4 moves, the first bump 7 can accurately push the first connecting rod 3, so that the clamping block 9 can be accurately inserted into the clamping groove or separated from the clamping groove.

In one embodiment, the locking groove and the locking block 9 are both cross-shaped. So, through rotating second pivot 10, make fixture block 9 insert in the draw-in groove, can inject cabinet door 2 on 0 degree, 90 degrees and 180 degrees three angles.

In one embodiment, the surface of the first protrusion 7 contacting the second link 4 is arc-shaped, and the end of the second link 4 near the first link 3 is arc-shaped, so as to more easily and conveniently push the second link 4 to move through the first protrusion 7.

In one embodiment, the second protrusion 8 is hemispherical, so as to facilitate the movement of the first link 3 pushed by the second shaft 10 and the second protrusion 8.
