The specific embodiment
Shown in Fig. 1-2, this mechanical tube post ignition lock, comprise: housing 1, be located at the pilferproof closure 2 on the housing, the igniting lock core 6 of identification key mechanical profile of tooth, the dead bolt 13 of locking tubing string, transmit the camshaft that rotatablely moves 15 of igniting lock core, rotatablely moving of lock core of igniting is converted to the straight-line cam stator 20 of camshaft, dead bolt and latch 8 are rigidly connected, dead bolt is connected with the back-moving spring 12 of locking by latch 8, camshaft is connected with the igniting lock core by coupling pin 19, also be provided with the bonnet 3 of closure casing inner member, bonnet is fixed to the rear portion of housing by safetied pin 10, the antitheft triggering pin 9 of bonnet is connected to bonnet, also be provided with the antitheft lock latch parts 7 of locking latch, antitheft lock latch parts connects compression torsionspring 11, floating ring 5 is connected with cam stator 20 by floating ring spring 14, the antitheft triggering pin of lock core 4 is against floating ring, and the two ends of compression torsionspring connect respectively pilferproof closure and antitheft lock latch parts.
This mechanical tube post ignition lock is shared an antitheft lock latch parts by the triggering pin that uses two different directions, use a compression torsionspring to cooperate antitheft lock latch parts, after the triggering pin of realizing any one direction in these two different directions is triggered, all will cause the work of antitheft lock latch parts, thereby the latch of inside is locked, and latch and dead bolt are the connections of rigidity, therefore, the latch locking action can prevent that dead bolt from returning, and guarantees that tubing string locks all the time, and illegal user can't normally use automobile.
Preferably, antitheft lock latch parts 7 is provided with position, top rib 23, the first clearance groove 24, Second gap groove 25.
Preferably, camshaft also connects camshaft return spring 17, is provided with spring washer 16 between the two.
Preferably, latch 8 also comprises the latch locking slot 21 that holds antitheft lock latch parts 7.
Preferably, camshaft also comprises the camshaft torsionspring 18 of the return of unstable state igniting gear.
Operating principle of the present utility model is as follows:
When igniting after lock core 6 illegally taken out, the locking plate that is used for identification shaped as key bit coding in the whole igniting tubing string lock system does not exist, as shown in Figure 3.At this moment, cam stator 20 moves along X-direction under the effect of floating ring spring 14, and promotes floating ring 5.After floating ring 5 moves along X-direction, the antitheft triggering pin 4 of lock core also will have enough spaces 22 to the X-direction motion, as shown in Figure 4.This moment antitheft lock latch parts system works, compression torsionspring 11 will release energy, promoting antitheft lock latch parts 7 moves along the T direction, and the antitheft triggering pin 4 of pushing lock cylinder moves towards X-direction in the process of motion, after the antitheft triggering pin 4 of lock core is pushed out fully, antitheft lock latch parts 7 will continue to move along the T direction, and this moment, because the existence of the first clearance groove 24 on the antitheft lock latch parts 7, the antitheft triggering pin 9 of bonnet does not stop antitheft lock latch parts 7 to move along the T direction, until its complete dropping in the latch locking slot 21, as shown in Figure 5.This moment, latch 8 will be by antitheft lock latch parts 7 restrictions along moving of-Y-direction, and namely dead bolt 13 can't be retracted in the housing 1 along-Y-direction, thereby keeps dead bolt 13 to drop on all the time in the tubing string, and illegal user can't normally use automobile.And because anti-theft locking door bolt part 7 is to the locking action of T direction, antitheft lock latch parts 7 will stop the antitheft triggering pin of lock core 4 to move along X in the other direction, avoid illegal user to use other external tools with the release of antitheft lock latch parts system.
When housing bonnet 3 by illegally with after housing 1 separates, as shown in Figure 6.The antitheft triggering pin 9 of bonnet will not have the support of housing bonnet 3, possess to the motion of-Y-direction may, at this moment, antitheft lock latch parts 7 will be along W to rotation under the twisting action of compression torsionspring 11, in the process of rotating, position, top rib 23 on the antitheft lock latch parts 7 will promote the antitheft triggering pin 9 of bonnet and move along-Y-direction, as shown in Figure 6.When antitheft lock latch parts 7 turned to position 26, position, the top rib 23 on the antitheft lock latch parts 7 will be stopped by the stop bit muscle on the housing 1, stops operating, shown in Fig. 7 (b).At this moment, compression torsionspring 11 will promote anti-theft locking door bolt part 7 and move along the T direction, and because the existence of Second gap groove 25 on the anti-theft locking door bolt part 7, the antitheft triggering pin 4 of igniting lock core does not stop antitheft lock latch parts 7 to move along the T direction, shown in Fig. 7 (a), until its complete dropping in the latch locking slot 21, as shown in Figure 8.This moment, latch 8 will be by antitheft lock latch parts 7 restrictions along moving of-Y-direction, and namely dead bolt 13 can't be retracted in the housing 1 along-Y-direction, thereby keeps dead bolt 13 to drop on all the time in the tubing string, and illegal user can't normally use automobile.And because the existence of the gear rib 27 on the latch, external tool can't touch antitheft lock latch parts 7, makes antitheft lock latch parts system works more reliable.
Adopt the beneficial effects of the utility model: can effectively avoid mechanical ignition to be locked in the process of use by unauthorised broken reaching the purpose of release tubing string, thereby guarantee that the ignition lock dead bolt drops in the tubing string all the time, prevents the illegal use of automobile.This cover burglary-resisting system provides the triggering pin of both direction to share an antitheft lock latch parts system, use a compression torsionspring to realize the rotation of antitheft lock latch parts, the actions such as locking latch, and after avoiding antitheft lock latch parts system works, can't use external tool contact or the antitheft lock latch parts of release system, guarantee the reliability of anti-theft feature.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment all still belong to the protection domain of technical solutions of the utility model.
