Specific embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
The technical solution of the utility model embodiment is clearly and completely described in the attached drawing of type embodiment.Obviously, it is described
Embodiment is the part of the embodiment of the utility model, instead of all the embodiments.Based on described the utility model
Embodiment, those of ordinary skill in the art's all other embodiments obtained on the premise of without creative work, all belongs to
In the scope of the utility model protection.
Referring to shown in Fig. 1,2,3,4, switchgear grounding switch and cabinet door interlock operate in switch cabinet 1
Between the operating device 2 of earthing switch and the rear cabinet door 3 of switch cabinet, operating device includes what is rotated around its center
Revolving part 4.
Fixing assembling has lock 5 on rear cabinet door, has lockhole 6 on lock；Insertion lock lock is equipped on switch cabinet
Locking is formed in hole or departs from the locking bar 7 that lock lockhole is unlocked, is installed on switch cabinet and locking bar is held
It carries and the loading plate 8 of guiding is formed in movement, offer on loading plate and passed through for locking bar, locking bar is moved to form guiding
Relief hole.
And in 4 rotation process of revolving part, to transfer the urging force of revolving part generation, locking bar insertion lock lockhole is driven
6 or depart from lock lockhole 6 transmission mechanism.
In specific implementation, revolving part is worm gear, and operating device further includes the worm screw 9 that transmission cooperation is carried out with worm gear, screw rod
