Abstract
The utility model relates to an emergency unlocking device of a power distribution cabinet, relating to the field of power distribution cabinet technology. The emergency unlocking device of the power distribution cabinet comprises a cabinet back door and a grounding switch, interlocking members are connected on the cabinet back door, and a square tapered end is connected on the operation shaft of the grounding switch; the interlocking members are a square hole on the cabinet back door corresponding to the square tapered end and a covering connecting lock plate arranged on the square hole, the lock plate is equipped with a long waist hole used for realizing the interlocking, and a normal interlocking function is realized by arranging an external bolt on the square hole of the cabinet back door. When the grounding switch and the interlocking members are damaged to be not in linkage, the back door can be opened by disassembling the lock plate on the door, thereby realizing the emergency unlocking.
Description
Technical field
The utility model relates to the power distribution cabinet technical field, particularly the emergency unlocking device of power distribution cabinet.
Background technology
The emergency unlocking device of existing power distribution cabinet; Mainly comprise door and jam plate, the part in that the back door and the earthed switch of cabinet are realized interlocking is the earthed switch locking part; With whole gate interlock behind the cabinet; When situation such as machinery is stuck, distortion, fracture damage occurring when the ground connection interlock assembly, can not transmission because of locking part itself, cause the back door to open.In this case, can only overhaul by force, thereby damage door, cause the damage of figure layer, structural failure, in most cases, can only do door again, the scene of being transported to is changed, and not only influence work, and expense is big.
The utility model content
The purpose of the utility model is: design a kind of emergency unlocking device of power distribution cabinet, to overcome defective of the prior art, can not damage the Men Bingneng maintenance, can restore easily again.
According to above-mentioned purpose; The technical scheme of the utility model is: a kind of emergency unlocking device of power distribution cabinet; Comprise cabinet back door and earthed switch, cabinet is connected with locking part on the back door, is connected with square lock head on the earthed switch operating axis; It is characterized in that: described locking part is a square hole corresponding with square lock head on the cabinet back door, and the cover type that is provided with on the described square hole connects jam plate.
Described jam plate is provided with the long lumbar hole of realizing interlocking, and is installed on the square hole at cabinet back door through external screw.
Described improvement thinking is: the part in that the back door and the earthed switch of cabinet are realized interlocking by the whole plate of original one, changes detachable structure into.
Be divided into two whole door at interlocking part, let interlock spare, be attached on the door, just in case situation occurs, dismountable it.If just can not realize interlock and forget to install.Through STRUCTURE DECOMPOSITION, function can realize.
Why earthed switch can be operated is that the square spigot of shutting time pushing earthed switch operating axis by the back door breaks away from cabinet column square hole, thereby realizes release.As long as the also opening square hole of correspondence position at the cabinet back door pastes a jam plate again and blocks square hole on door, open long lumbar hole on the jam plate to realize interlocking, fix with external screw.
Compared with prior art, advantage of the utility model and beneficial effect: the utility model product has been realized normal interlock, when not linking when the damage of earthed switch locking part occurring, lays down the jam plate on the door, just can practice backdoorism, and realizes emergency release.
