Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of long-time operation is provided after, can not cause the interlock of the phenomenon that the switch cubicle back door do not open.
The technical scheme that the utility model is taked is:
A kind of back door interlocking device of high-tension switch cabinet comprises cabinet, back door and earthed switch operating axis, it is characterized in that: be set with lock tube 10 on the described earthed switch operating axis 7, be shaped on notched ring baffle on the lock tube 10; Described cabinet is provided with U-shaped guide pin bushing 9, has operation axis hole and lockpin hole on two risers of U-shaped guide pin bushing 9, operation axis hole place frame attaching ground switching manipulation axle 7, lockpin hole place frame dress lock pin 8; Go back frame on the described cabinet locking bar 4 is housed, locking bar 4 is connected with lock pin 8 by driving lever 1.
Further, described locking bar 4 is installed on the cabinet by bearing 5, between locking bar 4 and bearing 5 spring is installed, and the elastic force of spring makes locking bar 4 to the cabinet outer displacement.
Further, an end and the locking bar 4 of described driving lever 1 are hinged, and the middle part of the other end and lock pin 8 is hinged; Driving lever 1 is installed on the cabinet by driving lever seat 2, and the middle part of driving lever 1 and driving lever seat 2 are hinged.
The beneficial effects of the utility model are:
1, interlock of the present utility model has been used transmission devices such as locking bar, driving lever, makes the position of lock pin can not cause displacement or skew because of long-term the use, has guaranteed the stability of single unit system, the phenomenon of not opening in the back door can not take place.
2, interlock of the present utility model does not need structure, position and the profile of back door and earthed switch operating axis are changed, and is convenient to existing high-tension switch cabinet is upgraded and transformed.
3, interlock of the present utility model, when the earthed switch operating axis rotates when not in place, lock pin can not be inserted in the lock tube, and when the lock pin displacement was not enough, the displacement of locking bar can not put in place, made the back door not open; After opened at the back door simultaneously, lock pin blocked lock tube, makes the earthed switch operating axis not rotate, and had guaranteed the fail safe of operation.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
Shown in Fig. 1,2,4, back door interlocking device of high-tension switch cabinet, comprise back door and earthed switch operating axis, guide pin bushing and some bearings are installed on the high-tension switch cabinet cabinet, wherein guide pin bushing 9 is used for fixing earthed switch operating axis 7 and lock pin 8, guide pin bushing U-shaped in general channel has operation axis hole and lockpin hole on two risers of U-shaped, make lock pin to move vertically.In guide pin bushing one side, lock tube 10 is installed on the earthed switch operating axis, lock tube 10 is sleeved on the earthed switch operating axis, is shaped on notched ring baffle on the lock tube, and lock pin inserted in the breach of ring baffle when opened at the back door, the rotation of restriction earthed switch operating axis.
Lock pin 8 links to each other with locking bar 4 by driving lever 1, operates the axial displacement of lock pin 8 by the reciprocating motion of locking bar.As shown in Figure 1, locking bar is installed on the cabinet by bearing 3, bearing 5, and is parallel with earthed switch operating axis, lock pin.One end and the back door of locking bar are equipped with the device with locking back door function, and the other end of locking bar and driving lever 1 are hinged, and the middle part of driving lever 1 is hinged on the driving lever seat 2, and the middle part of the other end of driving lever 1 and bearing pin 8 is hinged.Between locking bar 4 and the bearing 5 spring 6 is installed, under the effect of no external force, utilizes the elastic force of spring 6 that locking bar is moved outside cabinet, make lock pin 8 insert in the lock tube 10.Bearing 3,5 and driving lever seat 2 all are fixed on the cabinet, and wherein driving lever seat 2 is fixed on the below of guide pin bushing 9.
When opening the back door, rotation earthed switch operating axis 7 makes earthed switch be in "on" position earlier, guarantees the fail safe of operation.After the earthed switch operating axis is rotated, open the back door again, the locking states that open between hour locking lever and the back door at the back door is removed.As shown in Figure 1, this moment, the elastic force of spring made locking bar 4 vertically to the cabinet outer displacement, drove driving lever 1 and clockwise rotated, and driving lever 1 is stirred lock pin 8 and inserted in the lock tube 10.At this moment, lock pin 8 blocks lock tube 10, and the earthed switch operating axis can not effectively rotate, and guarantees that earthed switch is in "on" position, has guaranteed security performance.Because interlock has been used transmission devices such as locking bar, driving lever, make the position of lock pin can not cause displacement or skew simultaneously, guaranteed the stability of single unit system, the phenomenon of not opening in the back door can not take place because of long-term the use.
When closing back door, form locking states between locking bar and the back door, make locking bar to the cabinet intrinsic displacement.As shown in Figure 3, the displacement of locking bar 4 drives driving lever 1 and rotates counterclockwise, and driving lever 1 is stirred lock pin 8 and withdrawed from lock tube 10.At this moment, the earthed switch operating axis can freely rotate.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
