Description
Technical field
The present invention relates to door lock field, specifically refer to a kind of lock of antitheft rear lock.
Background technology
Existing door body is generally provided with opal, offender is sometimes by destroying opal, then unblanked from pull handle in door by instrument, this process operation is comparatively simple, is easy to realize, is unfavorable for antitheft, the present invention is directed to this scheme and design a kind of anti-theft device especially, the unlocking difficulty of this scheme can be increased substantially, and then be significantly decreased through the situation that opal carries out unblanking and occur, improve the theftproof performance of door lock.
Summary of the invention
The object of the present invention is to provide a kind of lock of antitheft rear lock, to solve the problem.
Object of the present invention is achieved through the following technical solutions:
A kind of lock of antitheft rear lock, comprise an Internal handle, lock body and the lock core be arranged in lock body and burglar-proof mechanism, door Internal handle is rotated by contiguous block and is arranged on lock body, described burglar-proof mechanism comprises regulating block, spring, push rod, clamping joint and clamping block, regulating block is connected with push rod one end, and spring housing is located on push rod, and door Internal handle has jack, the described push rod other end is connected with clamping joint, and described clamping joint contacts with clamping block after running through jack and lock core; Described clamping joint end is provided with cruciform joint, transitional pore is had in the middle part of described clamping block, the blind hole matched with cruciform joint is provided with bottom transitional pore, and on clamping block, also have the stopper slot of quadrant, the outer circle wall of stopper slot is also provided with the gag lever post coordinated with stopper slot, is fixed with the spacer pin engaged with lock core at the two ends of clamping block.
When the present invention unblanks, clamping block must be operated lock core is connected with door Internal handle, then rotary door Internal handle can be unblanked, move handle by opal hook after can preventing lawless person from destroying opal to unblank, lawless person needs at clamping block, lock core to be connected can be unblanked with door Internal handle, but from outside pole difficulty operation clamping block, the difficulty of being unblanked by opal can be increased considerably, and then improve the theftproof performance of door lock.During use, normal rotation door Internal handle, regulating block is inwardly pressed down simultaneously, make the displacement on the clamping joint occurred level direction of extraneous impetus lower push rod end, until cruciform joint inserts the blind hole in clamping block, complete engaging between cruciform joint with blind hole, along with door inner handle 90 degree rotation, the spacer pin at clamping block two ends directly engages with lock body, makes lock body and door Internal handle synchronous axial system, and then realizes lock body and unblank, in use, push rod needs to continue to bear the engagement between pressure guarantee cruciform joint and blind hole, and interaction force between user and regulating block reduces or when disappearing, push rod can outwards movement under the elastic force effect of the reply deformation of spring, now depart between cruciform joint and blind hole, directly cause unblanking to carry out, this just needs user to carry out rotation adjustment to regulating block, to realize aiming between cruciform joint with blind hole, in the present invention, clamping block has transitional pore and blind hole, namely when rotating regulating block, gag lever post rotates in stopper slot, and stopper slot is 90 degree of arc-shapeds, namely the maximum rotation scope of gag lever post is 90 degree, when gag lever post contacts with the extreme position of stopper slot, cruciform joint and blind hole realize aiming at, now regulating block is pressed down, cruciform joint is engaged again with blind hole, and then ensure the normal unlatching of lock body, the time of regulating block position is constantly debugged as this reduced user, ensure the smooth switch of security door.
As preferably, in the middle part of described transitional pore to bottom it conically, and described clamping joint end is the taper corresponding with the conical section of described transitional pore.In the alignment procedures of cruciform joint and blind hole, cruciform joint needs first to pass through transitional pore, and then contact with blind hole, for reducing regulating block in the aligning process, the reaction force of force person is affected, the middle and lower part of transitional pore is set to taper shape, and the end of clamping joint is also the taper shape adapted with transitional pore middle and lower part simultaneously, namely when cruciform joint and transitional pore contact internal walls, the bootable cruciform joint of inclined surface in transitional pore carries over down and slides in blind hole, so improve cruciform joint and blind hole aim at efficiency.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention has transitional pore and blind hole on clamping block, namely when rotating regulating block, gag lever post rotates in stopper slot, and stopper slot is 90 degree of arc-shapeds, namely the maximum rotation scope of gag lever post is 90 degree, when gag lever post contacts with the extreme position of stopper slot, cruciform joint and blind hole realize aiming at, now regulating block is pressed down, cruciform joint is engaged again with blind hole, and then ensure the normal unlatching of lock body, constantly debugging the time of regulating block position as this reduced user, ensureing the smooth switch of security door;
2, the present invention is in the alignment procedures of cruciform joint and blind hole, cruciform joint needs first to pass through transitional pore, and then contact with blind hole, for reducing regulating block in the aligning process, the reaction force of force person is affected, the middle and lower part of transitional pore is set to taper shape, and the end of clamping joint is also the taper shape adapted with transitional pore middle and lower part simultaneously, namely when cruciform joint and transitional pore contact internal walls, the bootable cruciform joint of inclined surface in transitional pore carries over down and slides in blind hole, so improve cruciform joint and blind hole aim at efficiency.
