Tongue, the cabinet door inner side are vertically arranged with elastic piece below lock tongue, are provided between the elastic piece upper end and cabinet door
Partition plate, is provided with limited block, the limited block is provided with slope surface, the door towards doorframe in the elastic piece away from cabinet door side
Frame is provided with pressing plate towards elastic piece bottom.
Through the above scheme, when opening cabinet door, swing handle opens door by after lock tongue disengaging and the conflict of doorframe, then
It is rotated further, allows handle to be horizontal so that lock tongue can climbs over slope surface, so that limited block blocks lock tongue, prevent lock
Tongue returns to horizontal level, so that also it is avoided that lock tongue collides with doorframe in the case of external force and causes lock tongue deformation
Situation.
Further, side of the elastic piece away from cabinet door is provided with support plate.
Through the above scheme, support plate is used to hold lock tongue, prevents it from misplacing.
Further, the elastic piece bottom is provided with rubber pad.
Through the above scheme, rubber pad can mitigate impact caused by elastic piece and clamp collision.
Further, it is provided with spring between the elastic piece bottom and cabinet door.
Through the above scheme, spring being capable of the recovery of assistant spring piece.
Further, the pressing plate sets reinforcing rib away from cabinet door side.
Through the above scheme, reinforcing rib can improve the intensity of pressing plate.
Further, the reinforcing rib is along horizontally arranged.
Through the above scheme, reinforcing rib can improve the intensity in pressing plate horizontal direction.
Further, side of the limited block away from doorframe is the plane of vertical elastic.
Through the above scheme, which can coordinate with lock tongue shape, lock tongue be carried out spacing.
Further, the bottom of the pressing plate and elastic piece contradicts.
Through the above scheme, pressing plate is used to press to elastic piece bottom, brings it about deformation.
In conclusion the utility model has the advantages that：
When opening cabinet door, swing handle by lock tongue depart from and the conflict of doorframe after door opened, then proceed to rotate, allow handle
Hand is horizontal, so that lock tongue can climb over slope surface, so that limited block blocks lock tongue, prevents lock tongue from returning to water
Prosposition is put, so that also it is avoided that colliding with lock tongue in the case of external force with doorframe and causing the situation of lock tongue deformation.

Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of high security switchgear, as shown in Figure 1,2 and 3, including cabinet door 1 and doorframe 2, it is provided with handle in cabinet door 1
Hand 11,11 upper end of handle penetrate cabinet door 1 and are provided with shaft 12, and one end that shaft 12 is located at the inner side of cabinet door 1 is set towards doorframe 2
There is lock tongue 13.Under 1 closed mode of cabinet door, handle 11 is in vertical state, and lock tongue 13 is in horizontality, and lock tongue 13
Doorframe 2 is blocked, so that cabinet door 1 be pinned.When opening cabinet door 1, lock tongue 13 is allowed to rotate downwards by swing handle 11, so that
Allow lock tongue 13 to depart from the conflict with doorframe 2, cabinet door 1 is opened.
An elastic piece 3 is provided with the lower section of lock tongue 13, is connected between the upper end of elastic piece 3 and cabinet door 1 by partition plate 31
Connect, the setting of partition plate 31, which allows between elastic piece 3 and cabinet door 1, reserves certain distance, and deformation space is reserved to elastic piece 3.In elasticity
The middle part of piece 3 is provided with limited block 4, and limited block 4 is provided with slope surface 41 towards doorframe 2, and the middle part of elastic piece 3 is directed away from doorframe 2
Side be extended support plate 42 so that when lock tongue 13 is swung down to 4 right side of limited block in Fig. 2, limited block 4 can block
Firmly elastic piece 3.The bottom of elastic piece 3 is provided with spring 43 between elastic piece 3 and cabinet door 1, can assistant spring piece 3 it is multiple
It is former.The pressing plate 5 for contradicting 3 bottom of elastic piece is provided with doorframe 2, rubber pad 44, energy are provided with the outside of the bottom of elastic piece 3
Enough mitigate elastic piece 3 and pressing plate 5 collides caused impact.Reinforcing rib 51 is provided with the back side of pressing plate 5, improves pressing plate 5
Intensity.
Explanation is embodied：
When opening cabinet door 1, swing handle 11 allows lock tongue 13 to open door after departing from the conflict with doorframe 2, then proceedes to turn
It is dynamic, allow handle 11 to be horizontal, so that lock tongue 13 can climb over the right side that slope surface 41 turns to limited block 4 in Fig. 2,
So as to which limited block 4 blocks lock tongue 13, lock tongue 13 is prevented to return to horizontal level, so that also it is avoided that with lock tongue 13 in external force
In the case of and doorframe 2 collide and cause the situation of 13 deformation of lock tongue.
When closing cabinet door 1, cabinet door 1 is promoted until rubber pad 44 and pressing plate 5 contradict to doorframe 2, then proceedes to promote cabinet
Door 1, crush board 5 by elastic piece 3 to 1 curving deformation of cabinet door, so as to allow limited block 4 and lock tongue 13 to separate, then handle 11
It is sagging under the action of self gravitation, and lock tongue 13 returns to horizontal level, blocks doorframe 2, so that cabinet door 1 be pinned.
