Description
Technical field
The utility model relates to a kind of sealing switch equipment, relates in particular to the door lock assembly that a kind of armouring type is removed the middle-set-type metal enclosed switchgear.
Background technology
The full name of mid-cabinet (Centrally Installed Switchgear) is removed the middle-set-type metal enclosed switchgear for the armouring type, and it divides four individual compartment, i.e. breaker chamber, cable vault, bus-bar room and control room.Because breaker chamber is positioned at the intermediate layer, removes the middle-set-type metal enclosed switchgear so be called the armouring type, is called for short mid-cabinet.
In pressure, the high tension substation, it is more that the arcing fault takes place at present.In case when having an accident, bigger to the external door impact force of mid-cabinet breaker chamber door and cable vault's door, so the tight form of structure of external door and door lock will directly influence the size of explosion-proof accident.
Generally with the screw bolt-type lock, promptly the hexagonal staking nut of staking M10 on the cabinet blocks the screw bolt-type lock core to existing mid-cabinet door lock device on the external door, and external door is shut the back and is screwed into the staking nut with the screw bolt-type lock core.The internal arc fault when taking place in this device, and the shock wave inner with switchboard promotes external door, and lock core spurs the staking nut simultaneously, may pull up the staking nut sometimes, makes external door be compelled to open; Simultaneously, the injustice because of the switch basis when this mid-cabinet is in place at the scene makes screw bolt-type lock core and staking nut not on same axle center, make door be difficult to locking, and it is loaded down with trivial details to lock a door.
The utility model content
The technical problem that the utility model will solve is in order to overcome the defective of prior art; A kind of door lock assembly of intermediate switchgear cabinet is provided; It has reduced cost of production, and explosion-proof is strong, simple in structure, easy to operate, efficiently solves basic injustice and makes difficult lock of door lock or the not tight problem of lock.
The technical problem that the utility model solved can adopt following technical scheme to realize:
The door lock assembly of intermediate switchgear cabinet comprises cabinet and external door, it is characterized in that, said cabinet is provided with lock shaft, and said lock shaft comprises a head and neck, and an end of said neck is connected with head, and the other end of said neck is connected with cabinet;
The lock shaft link position of said external door is provided with forward and backward clamping plate; Said rear plate is provided with and the corresponding door lock of lock shaft head hole; Be provided with the door lock plate between said front plate and the rear plate; Said door lock plate is provided with Pear-Shaped waist hole, and the macropore diameter in this Pear-Shaped waist hole is corresponding with the head of lock shaft, and the small aperture in this Pear-Shaped waist hole is corresponding with the neck of lock shaft; Also be provided with vertical slots on the said external door, one can be connected with the door lock plate through passing this vertical slots along the door handle of carrying that this vertical slots is slided.
In an embodiment of the utility model, said external door is provided with the weather strip that seals, and said weather strip is positioned at the inboard of door lock plate.
In an embodiment of the utility model, said door lock plate is fixed on the slide plate, said door lock plate through this slide plate with carry door handle and be connected.Further, in the utility model, also comprise locking device, said locking device comprises can withstand slide plate from the side, slides up and down snap close to prevent it.Further, in an embodiment of the utility model, said locking device can be key lock or electronic lock.
Upwards draw and carry door handle, drive the door lock plate and move upward, when the macropore in Pear-Shaped waist hole on the door lock plate when door lock hole on the rear plate overlaps, can make external door close or open; After external door is closed and is made lock shaft on the cabinet get into the door lock hole on the external door; Carrying door handle moves downward the door lock plate to pressing down; The aperture in Pear-Shaped waist hole overlaps on door lock hole on the rear plate and the door lock plate, and the aperture in Pear-Shaped waist hole is clamped the neck of lock shaft on the cabinet downwards on the door lock plate, and this moment, rotatable key lock made snap close withstand slide plate; Be that slide plate can not move upward, external door is locked.
Compared with prior art, the beneficial effect of the utility model is: 1, reduce the utilization of screw bolt-type lock, simple in structure, labor and material saving reduces cost, and has improved labour productive forces.2, be convenient to on-the-spot the installation, easy and simple to handle, can lock or open door-plate fast, improved the overhaul of the equipments rate.3, explosion-proof is strong, and the pressure that external door is born when reducing the internal arc fault has improved safety of operators.
