Description
Technical field
The present invention relates to mechanical lock technical field, structure is dismantled more particularly, to a kind of anti-violence of lockset.
Background technology
At present, in lock technology field, theftproof lock in order to improve the pursuit reinforced panel thickness of safe class all simply and
Plate material is solved, but when violence is dismantled still without too big effect.
The content of the invention
There is the defect for being unable to anti-violence forcible entry to overcome existing lockset, the invention provides a kind of simple and stable structure
The anti-violence forcible entry structure of reliable, anti-violence forcible entry lockset.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of anti-violence forcible entry structure of lockset, including starting bar, starting bar spring, limited block and limited block positioning
It is longitudinally arranged before and after axle, the starting bar, described limited block or so lateral arrangement, locking bolt or so transverse movement, the limited block
Positioned at the rear of the starting bar, the starting bar is arranged on the front side of lock body through door body by starting bar fixed seat；
The limited block is located at the top of locking bolt, and the right-hand member of the limited block is rotatably installed by limited block locating shaft
In lock body, it is longitudinally arranged before and after the limited block locating shaft, the postmedian of the limited block is provided with positioning hole；
The front end of the starting bar is contacted on catch, and the starting bar fixed seat is provided with step through-hole, described to open
The rear end of lever sequentially passes through door body, step through-hole from A-P and inserted in positioning hole, and the starting bar spring housing is mounted in startup
On the middle part of bar and in step through-hole；
The left end of the limited block is provided with neck, and when locking bolt stretches out starting bar retraction simultaneously, limited block is rotated down, its
On neck be stuck on the rear portion of locking bolt.
Further, the explosion-proof power forcible entry structure also includes installing Positioning screw, and the installation Positioning screw is from left to right
It is connected to through lock body in the neck of limited block.
Beneficial effects of the present invention are mainly manifested in：Simple and stable structure is reliable, shakes hands to be loosened or sudden and violent outside door body
Anti-dismounting structure startup can be triggered after power forcible entry deformation, lock body produces self-protection locking, and key and handle can not all open lock body,
Effectively solve panel and lock core and the risk that door is opened is dismantled by violence, this structure can be applied and existing various mechanical locks.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
1~Fig. 6 of reference picture, a kind of anti-violence forcible entry structure of lockset, including it is starting bar 1, starting bar spring 4, spacing
It is longitudinally arranged before and after block 2 and limited block locating shaft 5, the starting bar 1, the lateral arrangement of limited block 2 or so, locking bolt 6 or so
Transverse movement, the limited block 2 is located at the rear of the starting bar 1, and the starting bar 1 passes through starting bar fixed seat through door body
10 are arranged on the front side of lock body；
The limited block 2 is located at the top of locking bolt 6, and the right-hand member of the limited block 2 is rotatable by limited block locating shaft 5
In lock body 7, it is longitudinally arranged before and after the limited block locating shaft 5, the postmedian of the limited block 2 is provided with positioning hole 202；
The front end of the starting bar 1 is contacted on catch 8, and the starting bar fixed seat 10 is provided with step through-hole, institute
State the rear end of starting bar 1 and sequentially pass through door body, in step through-hole insertion positioning hole from A-P, the starting bar spring 4 is set with
On the middle part of starting bar 1 and in step through-hole；
The left end of the limited block 2 is provided with neck 201, and when locking bolt 6 stretches out the retraction of starting bar 1 simultaneously, limited block 2 is downward
Rotation, neck 201 thereon is stuck on the rear portion of locking bolt 6.
Further, the explosion-proof power forcible entry structure also includes installing Positioning screw 3, and the installation Positioning screw 3 is certainly left extremely
The right side is connected in the neck 201 of limited block 2 through lock body 7.
In the present embodiment, the front end of starting bar spring 4 is connected with starting bar 1, and the rear end of starting bar spring 4 is contacted in step
On the step of through hole；The effect for installing Positioning screw 3 is to be used to install starting bar 1 and limited block 2, when starting bar 1 and limited block 2
After installing, Positioning screw 3 will be just installed and dismantled.
The present invention operation principle be：After starting bar 1 and 8 installation of lock body 7 and catch, the front end of starting bar 1
Contacted with catch 8, the rear end of starting bar 1 passes through door body 9, the stepped hole of starting bar fixed seat 10 and lock body and inserted in lock body
Certain distance in positioning hole 202 on limited block 2, meanwhile, starting bar spring 4 is compressed；Positioning screw 3 is now installed and started
Catch now normally can be dismantled and changed to bar 1, into Dual positioning, to the row of limited block 2；After the dismounting of Positioning screw 3 is installed,
Meanwhile, locking bolt 6 is locked；When catch 8 be disassembled or violence damage deformation, contacting between catch 8 and the front end of starting bar 1
It is released from, the distance of the rear end insertion limited block 2 of starting bar 1 is activated bar spring 4 and extracted outside positioning hole 202, and limited block 2 is with limit
Position block locating shaft 5 is to fall on the formation of the rear of locking bolt 6 under center of circle deadweight rotates to contact limitation locking；Now key and handle all can not
Release tamper limited block 2 and limitation locking is contacted to the formation of the rear of locking bolt 6；Therefore effectively solve panel and lock core by violence forcible entry and
The risk that destruction door is opened.
