Description
Technical field
The utility model relates to a kind of locking and emergency unlocking device of back door of high-tension switch cubicle.
Background technology
High-tension switch cabinet need to have " five is anti-" interlock, wherein have and prevent for preventing mistakenly entering charged chamber, this could open cabinet door after just requiring to only have earthed switch to close a floodgate, and it is exposed outside cabinet that this interlock of conventional products is interlocked, and may surprisingly be encountered and damages; And conventional equipment cannot be opened back door when there is emergency.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of avoid tapered end exposed outside cabinet, when there is emergency, can open fast locking and the emergency unlocking device of the back door of high-tension switch cubicle at back door.
The technical solution of the utility model is, a kind of locking and emergency unlocking device of the back door of high-tension switch cubicle with following structure are provided, comprise back door and be provided with latch shaft cabinet it also comprise locking bent plate, described locking bent plate is connected with back door is removable, the sidewall of the outer bottom of the inner side of described locking bent plate and cabinet door is affixed, on described cabinet and back door, be equipped with corresponding slot, the end, one end of described latch shaft can and be Long Circle through rectangular opening, and the end of described latch shaft is passed rectangular opening and stretched out in locking bent plate.
The described removable bolt that is connected to connects.
Adopt after above structure, the utility model compared with prior art, has the following advantages: owing to having set up locking bent plate, make the end of latch shaft be arranged on the inside of locking bent plate, avoid tapered end exposed outside cabinet; Because latch shaft end after grounding switch tripping is that Long Circle cannot be deviate from from locking bent plate rectangle locking mouth, back door just cannot be opened, thereby meets locking requirement again.When there is emergency, can unload hold-down screw from outside, locking bent plate just departs from back door like this, back door can be opened, and realizes emergency release function.
