Abstract
The invention relates to an anti-theft lock handle mainly comprises a handle and a lock rotating rod. The handle is mounted on a door inner lock housing through a fixing plate and a rotating limit sheet. The front end of the lock rotating rod is mounted in a lock square hole. The handle is L shaped and is provided with a through hole perpendicular to a straight rod of a lock. A pressure rod capable of moving back and forth is mounted inside the through hole. The rear end of the lock rotating rod is provided with a flat connector. The front end of the pressure rod is provided with a flat connection groove correspondingly. A return spring is disposed between the lock rotating rod and the pressure rod. Normally, under the action of the return spring, the pressure rod separates from the lock rotating rod; after the handle is pressed by applying force from the above, the handle idly rotates only and the door lock cannot unlock; only after the pressure rod is pressed inward and combines with the lock rotating rod and the handle is rotated, a door opens. The anti-theft lock handle is reasonable in structure, convenient to operate and use and high in safety coefficient, and theft-proof performance of the lock is greatly improved.
Description
Technical field
The present invention relates to a kind of lockset accessory, specifically a kind of theftproof lock handle.
Background technology
As everyone knows, safe-guard door lock kind is a lot, includes cylinder lock, blade lock, magnetic lock, IC card lock, Fingerprint Lock etc.In general, the door Internal handle of theftproof lock mainly comprises lock body bull stick, handle etc., and lock body bull stick one end is arranged in lock body square hole, and the other end is directly connected with handle.At indoor rotary door Internal handle, by lock body bull stick, can directly stir dead bolt, safe-guard door lock is opened.This action of unblanking easily to open the door has potential safety hazard.Outdoors, unload opal, by the opal hole on security door, with instrument, stretch into and in door, press an Internal handle and also safe-guard door lock can be opened.The antitheft Internal handle of locking a door of this spline structure greatly reduces the safety factor of safe-guard door lock.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, easy for operation, the theftproof lock handle that safety factor is high.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of theftproof lock handle, it mainly comprises handle and lock body bull stick, described handle is arranged in an internal lock body case by fixed head and rotary spacing sheet, lock body bull stick front end is arranged in lock body square hole, it is characterized in that: described handle is L-type, its straight-bar perpendicular to lock body is provided with a through hole, and a depression bar that can move forward and backward is installed in through hole; Described lock body bull stick rear end is provided with flat type connector, and depression bar front end correspondence is provided with flat type mouth of connecting trough, is provided with a back-moving spring between lock body bull stick and depression bar.
Depression bar rearward end of the present invention exposes with respect to the through hole protrusion of handle straight-bar.
Lock body bull stick of the present invention is provided with positive stop lug boss, and its front portion is arranged in lock body square hole by the restriction of fixing catch.
Fixed head of the present invention and be fixedly also provided with an idle running sleeve between catch.
The depression bar that having increased on handle of the present invention one can be separated with lock body bull stick, be connected, during use, depression bar is under the effect of back-moving spring conventionally, and itself and lock body bull stick, in released state, firmly press handle from top, and handle only can dally and cannot open door lock.Only have and press inwards depression bar and make it when lock body bull stick is combined, turning handle just can be opened door.Against existing technologies, the present invention is rational in infrastructure, easy for operation, and safety factor is high, has greatly improved the theftproof performance of lockset.It is suitable for doing the security door Internal handle of locking a door.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be further described.
Fig. 1 is that the present invention forms structural representation.
Label in figure is: 1. lock body, 2. lock body bull stick, 3. fixedly catch, 4. back-moving spring, 5. idle running sleeve, 6. fixed head, 7. rotary spacing sheet, 8. handle, 9. depression bar.
The specific embodiment
As can be seen from Figure 1, a kind of theftproof lock handle, it mainly comprises handle 8 and lock body bull stick 2, and described handle 8 is arranged in an internal lock body case by fixed head 6 and rotary spacing sheet 7, and lock body bull stick 2 front ends are arranged in lock body 1 square hole.Wherein concrete composition, structure and the effect thereof of fixed head 6 and rotary spacing sheet 7 belong to prior art, repeat no more.
Feature of the present invention is: described handle 8 is L-type, and its straight-bar perpendicular to lock body is provided with a through hole, and a depression bar that can move forward and backward 9 is installed in through hole; Described lock body bull stick 2 rear ends are provided with flat type connector, and depression bar 9 front end correspondences are provided with flat type mouth of connecting trough, are provided with a back-moving spring 4 between lock body bull stick 2 and depression bar 9.Press inwards depression bar 9, the flat type mouth of connecting trough on it engages with lock body bull stick 2 flat type connectors, and turning handle 8 can drive lock body bull stick 2 to rotate.By lock body bull stick 2, stir dead bolt, open door lock.Described back-moving spring 4 can be arranged in the front portion of straight-bar through hole.Unclamp depression bar 9, it is under the effect of back-moving spring 4, and with lock body bull stick 2 released states, now turning handle 8, and 8, handle can dally and cannot open door lock.
Further, described depression bar 9 rearward end expose with respect to the through hole protrusion of handle 8 straight-bars.Be convenient to like this press inwards depression bar 9.
Further, described lock body bull stick 2 is provided with positive stop lug boss, and its front portion is arranged in lock body square hole by 3 restrictions of fixing catch.Like this, lock body bull stick 2 can coordinate with lock body 1 is stable, limits it and departs from lock body.
Further, at the straight-bar front end of handle 8, described fixed head 6 and be fixedly also provided with an idle running sleeve 5 between catch 7.It is equivalent to the prolongation of handle 8 straight-bar through holes.Under this state, described back-moving spring 4 is arranged in idle running sleeve 5.
The depression bar 9 that having increased on handle 8 of the present invention one can be separated with lock body bull stick, be connected, during use, depression bar 9 is under the effect of back-moving spring 4 conventionally, and itself and lock body bull stick 2 are in released state, from top, firmly press handle 8,8, handle can dally and cannot open door lock.Only have when pressing inwards depression bar 9 and make it with 2 combination of lock body bull stick, turning handle 8 just can be opened door.Outdoors, even if unload opal, by the opal hole on security door, with instrument, stretch in door and press inside door handle 8 like this, 8, handle can dally and cannot open door lock.The antitheft Internal handle of locking a door of this spline structure has improved the safety factor of safe-guard door lock greatly.
The present invention is rational in infrastructure, easy for operation, and safety factor is high, has greatly improved the theftproof performance of lockset.It is suitable for doing the security door Internal handle of locking a door.
