Abstract

The utility model relates to a securing anti-theft door, which is composed of a door body and a built-in lock arranged on the door body. A guard cover plate is arranged on the position of a locking hole exposed from the built-in lock of the door body; the locking structure is a coded lock when the guard cover plate is closed. The built-in lock is arranged in the lock case of the door body, and a box cover faced to the locking hole is the guard cover plate. A linkage piece can be arranged between the bayonet of the guard cover plate and the rotary lock plate of the coded lock. The guard cover plate controlled by the coded lock protects the lock core of the built-in lock and the locking hole from breaking. Only when the coded lock and the guard cover plate are firstly opened, the built-in lock can be unlocked with the key to increase the anti-theft effect.

Description

Safety anti-theft door

Safety anti-theft door is a kind of security door of open and close, the vandal-proof safeguard structure that is provided with at the position of built-in lock, and the security door of the chain insurance that constitutes.

Existing security door has the built-in lock that steel door body and door body are provided with.Be arranged on the built-in lock of a body, its lockhole all exposes on the surface, be convenient to open, but easily destroyed by the people, as pounded, drilled, get clogged etc.The security door that has is arranged on the side with lockhole, though can be anti-drilling, do not prevent being pounded, getting clogged etc.The key of these security doors is easily taken away by other people and is directly opened the door in addition, is perhaps opened after the preparation in good time, does not reach antitheft effect.

The purpose of this utility model is a kind of lock core and lockhole that prevents to destroy built-in lock of design, the security door of double insurance.

The utility model is to realize by following scheme.The utility model safety anti-theft door scheme is, has the built-in lock that a body and door body are provided with, and its design feature is that lock core and the lockhole place that the built-in lock at the door body exposes is provided with protective cover plate, and the pinning structure after protective cover plate is closed is a coded lock.Just outside existing security door built-in lock, add the protective cover plate of one coded lock control again.Protective cover plate is protecting the lock core of built-in lock and lockhole not to be destroyed.Simultaneously, have only and to open built-in lock with key after opening coded lock and cover plate earlier, so even take key, not knowing has more increased antitheft effect to the password door of also not opening.Protective cover plate is located at outside the built-in lock, mainly is lock core and the lockhole that covers built-in lock, so the lock core of built-in lock and lockhole are arranged on which position of a body, which position protective cover plate just is arranged on.Protective cover plate can be the upset cover plate hinged with the door body, also can be the drawing and pulling type cover plate that is slidingly matched with the door body.Built-in lock preferably is arranged in the lock box of a body, lockhole towards lid be protective cover plate.The mode that coded lock pins protective cover plate can be the multiple mode of the structure of coded lock pinning in the past.Coded lock can be arranged on protective cover plate, locks mutually with the bayonet socket that is fixed on a body, also can be arranged on a body, locks mutually with the bayonet socket of protective cover plate, constitutes different pinning structures.Coded lock can directly pin with bayonet socket and be connected, and also can pin with bayonet socket by interlocking member to be connected.The bayonet socket that generally is protective cover plate is corresponding with the rotation jam plate of coded lock, directly blocks and opens, and perhaps is provided with interlocking member between the rotation jam plate of the bayonet socket of protective cover plate and coded lock, carries out indirect blocking and opening.The bayonet socket of protective cover plate inboard is corresponding with the rotation jam plate of coded lock, and perhaps and preferably be provided with slide bolt between the coded lock, chain by slide bolt is convenient to the reasonable preparation of coded lock and protective cover plate and built-in lock.

The utility model is compared with existing technology thus, and having security door is to adopt coded lock to control its built-in lock to open, and the unlatching lock core and the lockhole of built-in lock are not exposed, and has protected built-in lock not to be destroyed; And the parts that coded lock exposes are thicker, and intensity is very high, and are unsuitable destroyed, also do not open coded lock even destroyed; The built-in lock of coded lock and door has played the effect of double anti-theft again.

Accompanying drawing has been represented a kind of safety anti-theft door structural representation of the utility model.Fig. 1 is the contour structures schematic diagram in safety anti-theft door front, and Fig. 2 is the built-in lock of safety anti-theft door and the linkage structure partial sectional view of coded lock.Example below in conjunction with accompanying drawing further specifies the utility model.

This safety anti-theft door has the built-in lock 3 that a body 7 and door body are provided with, and at built-in lock 3 positions of door body lock box 4 is being set.Built-in lock is installed in the lock box, is provided with the protective cover plate 5 of lock box at the place, lockhole opposite that built-in lock exposes, the pinning structure after protective cover plate is closed is the coded lock structure.Coded lock is arranged on the door body of lock box top, and the fixedly scale lock collar of the knob of coded lock and cooperation is arranged on the external side of door, and the lock core part knob rotating shaft of coded lock and the jam plate of coaxial superposition are located in the body.Be provided with interlocking member slip plate 2 between the bayonet socket 6 of protective cover plate and the rotation jam plate of coded lock, the bayonet socket that is equivalent to the protective cover plate inboard is provided with slide bolt, and the rear end of latch is corresponding with the rotation jam plate of coded lock.After protective cover plate was closed, the inboard bayonet socket plate that slided inserted and pins, and the rotation jam plate of rotational password lock limits the slip plate, can not slide.Coded lock pins protective cover plate by the slip plate, is protecting built-in lock and lock core lockhole effectively.When the knob that twists coded lock in order, will rotate the jam plate opening in slip plate rear end, the slip plate just can slide, and withdraws from from the bayonet socket of protective cover plate inboard.So just can dig protective cover plate, expose the built-in lock core in it, can open built-in lock and security door with key.

Claims
