The technical scheme in the invention for solving the above technical problem 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 described in the utility model is protruded and is exposed with respect to the through hole of handle straight-bar.
Lock body bull stick described in the utility model is provided with positive stop lug boss, and its front portion is arranged in lock body square hole by fixing catch restriction.
Between fixed head described in the utility model and fixing catch, be also provided with an idle running sleeve.
On the utility model handle, increased by one can with the separation of lock body bull stick, the depression bar that is connected, when use, depression bar is under the effect of back-moving spring conventionally, itself and lock body bull stick, in released state, firmly press handle from top, handle only can dally and cannot open door lock.Only have and press inwards depression bar and make it in the time that lock body bull stick is combined, turning handle just can be opened door.Against existing technologies, the utility model 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 utility model is described further.
Fig. 1 is the utility model composition structural representation.
Label in figure is: 1. lock body, 2. lock body bull stick, 3. fixing 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 utility model 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.Stir dead bolt by lock body bull stick 2, 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 8,8, handle can dally and cannot open door lock.
Further, described depression bar 9 rearward end are protruded and are exposed with respect to the through hole 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 fixing catch 3 restrictions.Like this, lock body bull stick 2 can coordinate with lock body 1 is stable, limits it and departs from lock body.
