Description

The antitheft cabinet of a kind of improved mechanical type

Technical field

The utility model relates to a kind of antitheft cabinet, is meant a kind of cabinet that has the mechanical antitheft lock tool especially.

Background technology

Existing cabinet, particularly place outdoor various engineering generally to form by casing and chamber door with cabinet, because electrical type coded lock cost is high relatively, the lockset that this type of cabinet adopts all adopts the mechanical antitheft lock tool, and the general snap close and the simple hasp of lock nose that expose outside chamber door of adopting of lockset in the past forms, it is antitheft, the pick-proof poor performance, is easy to be torn open the robber by the lawless person, causes damage.

Utility model patent ZL93239934.7 discloses a kind of transformer tank double-lock type anti-theft device that is applicable to the various transformer tank of railway equipment, electrical relaybox and the similar box of other industry, be provided with the external lock that constitutes by outer clasp, external lock nose and lock, hidden movable connecting rod in external lock cooperates the internal lock that constitutes with interior jam plate, interior external lock combines double anti-theft.This technical scheme structure more complicated, switch lockset are extremely inconvenient.

Summary of the invention

The utility model provides a kind of simple in structure, switch convenience, good concealment, the antitheft cabinet of mechanical type that theftproof performance is strong.

The antitheft cabinet of a kind of improved mechanical type comprises casing, chamber door and the door lock assembly in hole with lock, and described door lock assembly comprises:

Be arranged at least one locking bar that can stretch into lockhole on the chamber door, an end that cooperates with lockhole on the locking bar has pin hole;

Be positioned at the telescopic latch on the casing, latch has keyhole or the key bar that is used to cooperate key;

Described locking bar one end stretches into lockhole and carries out chamber door when locking, and latch stretches into the pin hole of locking bar locking bar is located.

Described locking bar can be fixedly connected on the edge of chamber door, and chamber door is closed hour locking lever and stretched into lockhole, is controlling telescopic latch insertion pin hole, the location of realizing locking bar by key then.

Described locking bar also can be movably connected on the chamber door, this moment described chamber door be provided with can be on chamber door the door lock spiral arm of fixing point rotation, described locking bar is hinged on the door lock spiral arm by rotating shaft away from an end of pin hole; As preferably, the lateral surface of described chamber door is provided with the turning handle that is used to drive the rotation of door lock spiral arm, the control of being more convenient for.

As preferably, described locking bar has two, is that security performance increases though locking bar is more certainly, also increases cost relatively, also makes whole door lock assembly complicated more.

When locking bar is movably connected on the chamber door, as preferably, edge, top of stretching to chamber door of described two locking bars, another root stretches to the edge, the end of chamber door, promptly two equal vertical directions of locking bar are arranged, lockhole on the described casing is corresponding with the quantity and the position of locking bar simultaneously, makes locking bar can stretch into the lockhole corresponding with it.

When locking bar is movably connected on the chamber door, as another kind of optimal way, two one of locking bars stretch to the side edge of chamber door, another root stretches to the opposite side edge of chamber door, promptly two equal horizontal directions of locking bar are arranged, lockhole on the described casing is corresponding with the quantity and the position of locking bar simultaneously, makes locking bar can stretch into the lockhole corresponding with it.

When locking bar had two, the rotating shaft of the relative chamber door rotation of door lock spiral arm was positioned at the middle part of door lock spiral arm, and two locking bars are hinged on door lock spiral arm two ends respectively.

When locking bar has many, have at least one to have pin hole, also can be all to have pin hole, the latch of band keyhole or key bar further increases security performance according to the corresponding setting of quantity and position of the locking bar of band pin hole.

Telescopic latch can by spring be connected with casing realize flexible so that locking bar is locked or release, when latch need stretch, the location that use the key that cooperates with its keyhole or key bar could remove latch, this point can adopt prior art.

Rotate the door lock spiral arm when door lock assembly of the present utility model uses, the door lock spiral arm drives locking bar and moves, and makes another termination of locking bar stretch into or extract out lockhole.

The latch chamber door of extracting out in the lockhole can be opened, and stretches into the pin hole of locking bar when chamber door need lock by key control latch, makes the locking bar location to keep the lock-out state of chamber door.

The antitheft casing structure of mechanical type of the present utility model is simple, switch convenient; And door lock assembly all is located at cabinet inside, and disguised fine, theftproof performance is strong.
