Description

Car door safety-protection lock

Technical field

The utility model is related to a kind of safety-protection lock more particularly to a kind of car door safety-protection locks simple in structure, at low cost.

Background technology

Existing car door is more complicated with security protection lock construction, of high cost, is unfavorable for promoting and applying, and therefore, is badly in need of a kind of knot Structure is simple, it is at low cost, suitable for the safety-protection lock on car door.

Utility model content

The purpose of this utility model is to provide a kind of car door safety-protection locks simple in structure, at low cost.

To achieve the goals above, car door safety-protection lock provided by the utility model include shell, inner casing, lock core, actuator, Elastic component and pivot pin, the lock core are placed in the inner casing, and the shell is in rotationally to be socketed on outside the inner casing, the elasticity Part is socketed between the shell and the inner casing, and provides an elastic force for making the shell reset；The lock core with it is described Actuator connects, and the actuator is connect with the pivot pin, and sliding eye is equipped in the inner casing, and the pivot pin is slidingly arranged at In the sliding eye；Lock core rotation drives actuator rotation, so as to the actuator driving shaft pin upward sliding and support The shell.

Compared with prior art, since the utility model in the inner casing by being arranged a sliding eye, the pivot pin is made to slide It is set to dynamicly in the sliding eye, so as to drive the pivot pin to slide up and down using lock core and actuator, to realize Locking or release the lock are carried out to the shell and inner casing that mutually rotate, therefore, the structure very simple of entire safety-protection lock, cost is very low, Be conducive to promote and apply.

Preferably, offering annular groove in the middle part of the pivot pin, the outer surface of the actuator is equipped with protrusion, described convex It rises and is contradicted with the side walls of the annular groove.

Preferably, the actuator is equipped with card slot, the end of the lock core is equipped with fixture block, the fixture block and the card slot card Close connection.The actuator can be made effectively to be connected with the lock core in this way, to which driving torque is transmitted to the axis On pin.

Preferably, the car door safety-protection lock further includes handle, the handle is fixedly connected with the shell.The handle can To facilitate human hand operation to rotate the shell, the convenience used is improved.

Specifically, the car door safety-protection lock further includes cover, and the cover is articulated in the handle.The cover can be to prevent Only foreign matter enters in the lock core, avoids damage lock core.

Preferably, the elastic component is torsional spring.

Description of the drawings

Fig. 1 is the stereogram of the utility model car door safety-protection lock.

Fig. 2 is the exploded view of the utility model car door safety-protection lock.

Specific implementation mode

For the technology contents of the utility model, construction feature, the effect realized is described in detail, below in conjunction with embodiment And attached drawing is coordinated to be explained in detail.

As shown in Figure 1 and Figure 2, the utility model car door safety-protection lock 100 includes shell 1, inner casing 2, lock core 3, actuator 4, bullet Property part 5 and pivot pin 6, the lock core 3 be placed in the inner casing 2, the shell 1 is described in being rotationally socketed on outside the inner casing 2 Elastic component 5 is socketed between the shell 1 and the inner casing 2, and provides an elastic force for making the shell 1 reset；The bullet Property part 5 be torsional spring.The lock core 3 is connect with the actuator 4, and the actuator 4 is connect with the pivot pin 6, in the inner casing 2 Equipped with sliding eye 21, the pivot pin 6 is slidingly arranged in the sliding eye 21；The rotation of the lock core 3 drives 4 turns of actuator It is dynamic, so as to 4 driving shaft pin of the actuator, 6 upward sliding and support the shell 1.

As shown in Fig. 2, the middle part of the pivot pin 6 offers annular groove 61, the outer surface of the actuator 4 is equipped with protrusion (not shown), the protrusion and the side walls of the annular groove 61 contradict.The actuator 4 is equipped with card slot 41, the lock The end of core 3 is equipped with fixture block 31, and the fixture block 31 is connected together with the card slot 41.It can make the actuator 4 and institute in this way It states lock core 3 effectively to connect, to which driving torque to be transmitted on the pivot pin 6.

As shown in Figure 1, 2, the car door safety-protection lock 100 further includes handle 7, and the handle 7 is fixed with the shell 1 to be connected It connects.The handle 7 can facilitate human hand operation to rotate the shell 1, improve the convenience used.The car door safety-protection lock 100 Further include cover 8, the cover 8 is articulated in the handle 7.The cover 8 can prevent foreign matter from entering in the lock core 3, keep away Exempt to damage lock core 3.

When in non-locked state, the pivot pin 6 is fully located in the sliding eye 21, and the pivot pin 6 does not contact at The inner wall of the shell 1, the shell 1 are located under the resilient force of the elastic component 5 on home position, at this time can be with hand Turn moves the handle 7, and the handle 7 can drive the rotation of the shell 1 to open the door, and after loosing one's grip, the shell 1 is again in elastic force Under the action of reset.

When needing locking, lock core 33 can be turned using key, the lock core 33 is made to rotate, the lock core 3 drives institute The rotation of actuator 4 is stated, the protrusion and the side wall of the annular groove 61 of the pivot pin 6 of the actuator 4 contradict and jack up the pivot pin 6, the pivot pin 6 stretches out the sliding eye 21 and is resisted against the shell 1, and at this moment, the shell 1 cannot be rotated relative to inner casing 2, It is in the lock state.

Compared with prior art, since the utility model in the inner casing 2 by being arranged a sliding eye 21, make the pivot pin 6 are slidingly arranged in the sliding eye 21, so as to drive the pivot pin 6 to slide up and down using lock core 3 and actuator 4, Locking or release the lock are carried out to the shell 1 and inner casing 2 that mutually rotate to realize, therefore, the structure very simple of entire safety-protection lock, Cost is very low, is conducive to promote and apply.

Above disclosed is only the preferred embodiments of the utility model, cannot limit the utility model with this certainly Interest field, therefore equivalent variations made according to the patent scope of the utility model still fall within the utility model and are covered Range.
