The purpose of this utility model provides that a kind of lock thickness is thin, width is narrow; Anti-drilling, pick-proof, the anti-performance of pulling out are good; The built-in type theftproof lock that tapered end can be easy to remove and repair.
For reaching above-mentioned purpose, built-in type theftproof lock provided by the utility model, comprise tapered end and lock body, lock body comprises drain pan, face-piece, liner plate, main dead bolt and oblique tongue, main dead bolt and oblique tongue wherein are housed on drain pan, and main dead bolt is provided with a push rod, and tiltedly tongue is provided with one " L " shape shifting block, " L " shape shifting block is provided with an oblique tongue dial hole, connects by push rod and " L " shape shifting block between main dead bolt and the oblique tongue; Drain pan and face-piece are formed a lock housing and are fixed on the liner plate, described tapered end is made up of inner lock head and outer tapered end, inner lock head and outer tapered end are cross-key four row's pellet shot from a slingshot top shelves formula structures, be with an anti-drill bushing on the tapered end outside again, wherein be provided with a shift fork between inner lock head and the outer tapered end, inside and outside tapered end is connected and fixed by the tapered end frame becomes one; Described tapered end vertically interts on lock housing, and with a screw on lock housing, the position correspondence of the shift fork between inside and outside tapered end is on the toggle mechanism of main dead bolt.
As a kind of improvement of the present utility model, also be provided with an insurance spring bolt mechanism in the lock body, this mechanism comprises knob core, knob shift fork, torsion spring, pendulum clamp dog, insurance dead bolt, described knob core is contained on the drain pan, the knob shift fork is housed on the knob core, be provided with a torsion spring between pendulum clamp dog and the drain pan, the knob shift fork contacts with pendulum clamp dog and insurance dead bolt.
As another kind of improvement the of the present utility model, this lock is provided with an Internal handle, Internal handle is contained on the inner trim panels, inner trim panels is contained in a side of lock body and is fixed on the inwall of door, wherein be provided with a square torsion bar in the Internal handle, the end that square torsion bar contacts with Internal handle is equipped with a spring, and the other end is inserted in the oblique tongue dial hole; Be provided with an insurance knob on described inner trim panels, on the insurance knob knob square shaft be housed, the knob square shaft is inserted in the knob in-core.
As another kind of improvement the of the present utility model, this lock is provided with an Internal handle and outer handle, and Internal handle is contained on the inner trim panels, and outer handle is contained on the balustrade exterior panelling, and inside and outside again decorative panel is contained in the both sides of lock body, is separately fixed on the inside and outside wall of door; Internal handle is connected by a square torsion bar with outer handle, and square torsion bar passes oblique tongue dial hole, and the end that square torsion bar contacts with outer handle is equipped with a spring; Be provided with an insurance knob on described inner trim panels, on the insurance knob knob square shaft be housed, the knob square shaft is inserted in the knob in-core.
As another kind of improvement the of the present utility model, be separately installed with pulling block and lower drawing block at the lock body upper and lower.
The utlity model has following characteristics:
(1) its tapered end is made up of inside and outside tapered end, the top latch device is arranged between inside and outside tapered end, when using key operated inner lock head to drive shift fork, be not subjected to the interference of outer tapered end, and when using key operated external lock head to drive shift fork, be not subjected to the influence of inner lock head yet, thereby reach the purpose that to use the smooth open and close lock of inside and outside tapered end separately; When tapered end needs repairing or changes, insert key in tapered end, the rotation shift fork just can wholely tapered end be extracted out in lock body in the appropriate location, and does not need to unload maintenance or the replacing that lock body carries out tapered end; Inside and outside tapered end adopts cross-key four row's pellet shot from a slingshot top shelves formula structures, has increased the secret key amount of lock, has reduced the mutual opening rate of lock, thereby has strengthened the function of keeping secret of lock; Outer tapered end is owing to be with an anti-drill bushing and inside and outside tapered end shift fork when not inserting key withstands in the lock housing with, thereby has anti-drilling, pick-proof, prevents the function of pulling out.
(2) it is provided with independent insurance spring bolt mechanism, when indoor will insure dead bolt and be threaded to lock-out state the time, and outdoor can not unblanking, thus reach function in indoor insurance; This mechanism can make the insurance dead bolt be locked in and stretch out or retracted position, thereby has avoided occurring because the pernicious consequence that mistake is closed the door and oblique tongue or relevant tiltedly tongue part is damaged can not open door or can not opens because the vibration of closing the door skids off the insurance dead bolt.
(3) owing to be provided with push rod and " L " shape shifting block in the lock body, make key can not only control main dead bolt and open, can also open oblique tongue, Internal handle promptly only is installed, significantly improved lock like this and be contained in door and go up tamper-resistant function afterwards so the utility model can only be installed single-grip; Double handle also can be installed simultaneously inside and outside handle promptly is installed simultaneously, make like this be locked in use to go up more convenient.
(4) the utility model can optionally be installed pulling block and lower drawing block, constitutes the world lock of Three-bearing, and the stretching out synchronously or retraction of pulling block and lower drawing block and main dead bolt in applications can drive a plurality of dead points device on the security door, thus the raising theftproof performance.
(5) owing to adopted said structure, make lock thickness size of the present utility model thinner, width dimensions is narrower, lock is installed for door and has been brought convenience.
