Abstract
The utility model relates to a lock gap compensator, which is composed of a lock catch box, a lock body and a lock bolt. The interior of the lock body is provided with a lock bolt for gap compensation with a slope; the lock bolt for gap compensation and the lock bolt are locked into the lock catch box simultaneously under the action of spring force; the locking gap of the lock is decreased and the friction to the lock bolt caused by the door frame is decreased under the action of the force to the lock catch box caused by the slope of the compensation lock bolt when the door is locked up; thereby, the life time of the lockset and the tightness of the door are enhanced; the door is enabled not to swing under the exogenic action, the lock bolt is ensured to lock at place, and the unlocking resistance can be reduced.
Description
The utility model relates to lockset and makes field, especially a kind of blank compensation apparatus of lock.
At present, traditional lockset structure mainly is made up of keeper, lock housing body, dead bolt.Dead bolt inserts in the keeper by stretching out in the lock body when locking.In use, if dead bolt and keeper gap are little, then dead bolt frictional force is big, also can send ear-piercing sound sometimes, even can not lock or breakdown.If dead bolt and keeper gap are big, the back door of then locking can be rocked, the sealing of influence door.
The purpose of this utility model provides a kind of blank compensation apparatus of lock, and it has overcome above-mentioned
The shortcoming that prior art exists.
The purpose of this utility model is achieved in that it is made up of keeper, dead bolt guide strip, lock housing body and dead bolt, compensation dead bolt in gap is installed in the described lock housing body, one end of gap compensation dead bolt is equipped with spring, the other end is the inclined-plane, and the inner end of described gap compensation dead bolt has a boss corresponding with the step that described dead bolt is provided with; Described gap compensation dead bolt leans against on the limit of dead bolt; There is a circular hole at the rear portion of gap compensation dead bolt, and spring is housed in the circular hole; Be with guide rod in the described spring, guide rod one end is fixed on the lock housing body; Described gap compensation lock bolt sleeve is on dead bolt, and spring is contained on the dead bolt between gap compensation dead bolt and the dead bolt guide strip, and the dead bolt guide strip is fixed on the lock housing body; Described spring also can be contained between gap compensation dead bolt and the dead bolt guide strip, and gap compensation dead bolt is contained on the dead bolt guide strip.
Owing to adopt such scheme, when door is locked, the locking gap of door is reduced, reduce doorframe to the dead bolt friction, improve the life-span of lockset and the sealing of door, Men Buhui is rocked under external force, and can guarantee that dead bolt is locked into the position, and can reduce the resistance of unblanking.
Below in conjunction with drawings and Examples the utility model is described further
Fig. 1 is the section of structure of first embodiment of the utility model;
Fig. 2 is the section of structure of second embodiment of the utility model;
Fig. 3 is the section of structure of the 3rd embodiment of the utility model.
1. keepers among the figure; 2. lock housing body; 3. dead bolt; 4. the gap compensates dead bolt; 5. spring; 6. step; 7. boss; 8. dead bolt guide strip; 9. circular hole; 10. guide rod
See also shown in the accompanying drawing, because three embodiment principle unanimities, so explanation simultaneously, keeper 1 has and dead bolt 3, gap compensation dead bolt 4 corresponding dead bolt holes, dead bolt 3 in lock housing body 2 and gap compensation dead bolt 4 be the energy slide-and-guide all, and an end of gap compensation dead bolt 4 has an inclined-plane, and dead bolt 3 can be by the boss of compensation dead bolt 4 lower ends, the 6 snapping gaps of the step on it, thereby can compensate dead bolt 4 unidirectional dragging to the gap, make in its withdrawal lock housing body; Dead bolt 3 is by transmission control device (not shown) transmission control, and the elastic force of spring 5 acts on the gap compensation dead bolt 4, and it is stretched out outside lock housing body 2.
The utility model in use, dead bolt 3 is sleeved on the dead bolt guide strip 8, under the effect of dead bolt 3 at transmission device, stretches out lock housing body 2 and inserts in the main lockhole of keeper 1, under the effect of spring 5 power, compensation dead bolt 4 in gap also stretches out lock housing body 2 along guide rod 10 thereupon and inserts in the keeper 1 simultaneously; Because the stress surface of gap compensation dead bolt 4 is the very little inclined-planes of gradient, the tip on inclined-plane is towards the gap of keeper 1, so gap compensation dead bolt 4 in the process of stretching out, constantly reduces with the gap of keeper 1, till no gap bullet is motionless, thereby reach the effect that compensates the lock body gap.When unblanking, the step 6 snapping gap compensate for clearance compensation dead bolts 4 compression springs 5 of dead bolt 3 make spring 5 that an outside elastic force be arranged, and have promptly finished and have locked, the whole process of breakdown; Spring 5 also can be enclosed between gap compensation dead bolt 4 and the dead bolt guide strip 8 as shown in Figure 3, and gap compensation this moment dead bolt 4 is sleeved on the dead bolt guide strip 8.
