Abstract
The utility model discloses an anti-theft structure for an automobile ignition switch. The anti-theft structure comprises a shell, an ignition lock cylinder arranged on the end portion of the shell. A clamping ring, a fixing block cooperating with the ignition lock cylinder to rotate and an actuating rod connected with the fixing block to rotate are arranged on the matching end face of the ignition lock cylinder and the shell, and the actuating rod and a locking dog slider cooperatively control a locking dog in linkage with the locking dog slider to extend an retract. An actuating rod pressure spring is arranged between the actuating rod and the shell, a locking pin is further arranged above the locking dog slider, the locking pin is pressed on the locking dog slider, a locking pin accommodating hole is formed in the shell, and a locking dog slider limiting groove matched with the locking pin is further formed in the locking dog slider. A cylindrical pin is arranged between the locking pin and the clamping ring. After the ignition lock cylinder is taken out, the locking dog slider still cannot rotate, and the locking dog is disposed in a steering column to function in locking and preventing thievery. Anti-theft performance of an automobile is further improved. The anti-theft structure can be widely applied to the field of ignition switches.
Description
Technical field
The utility model relates to automobile ignition switch field, especially relates to a kind of automobile ignition switch theft-prevention structure.
Background technology
The requisite parts of ignition lock in the car load of automobile, automobile, before normally travelling, need be controlled the flexible of dead bolt by rotating key, realizes locking and the release of steering hub column, improves the theftproof performance of automobile.After igniting lock core is removed, can drive dead bolt flexible by rotary action bar, realize the release of steering wheel tubular pipe, thereby lose anti-theft feature.
As Chinese Patent Application No. 201210495151.X discloses a kind of automobile ignition switch with mechanical type anti-theft function, include Switch main body, described Switch main body further includes and coordinates dead bolt cover plate and the arm of action installed, also further include spring hook, one end with crotch portion of described spring hook packs into Switch main body inner side; Between described dead bolt cover plate and arm of action, device has locating plate, on described arm of action, offer the groove for accommodating locating plate, described locating plate upper end has depression bar, and the other end with straight-bar of described spring hook stretches out Switch main body inner side and is fitted in the depression bar below of locating plate.Because the spring hook of this invention acts in inner walls, when dismounting is during lock core, do not encounter spring hook structure, directly lock core is taken out, then rotary action bar, still can release.Therefore still there is certain potential safety hazard in this structure.
Utility model content
The purpose of this utility model is to provide a kind of automobile ignition switch theft-prevention structure, solves the problem of losing anti-theft feature after existing automobile ignition switch igniting lock core is removed.
The utility model solves the technical scheme that its technical matters adopts: a kind of automobile ignition switch theft-prevention structure, comprise housing, be arranged on the igniting lock core of shell end, on igniting lock core and housing counterface, be provided with collar, coordinate the fixed block rotating with igniting lock core and connect the arm of action of rotation with fixed block, arm of action coordinates with dead bolt slide block to be controlled and dead bolt that dead bolt slide block links stretches; One end diameter that arm of action coordinates with fixed block is greater than one end that arm of action coordinates with dead bolt slide block; Between one end that described arm of action coordinates with fixed block and housing, be provided with arm of action stage clip, above dead bolt slide block, be also provided with lock pin, lock pin is pressed on dead bolt slide block, is provided with lock pin placement hole on housing, is also provided with the dead bolt slide block limited impression coordinating with lock pin on dead bolt slide block; Between lock pin and collar, be provided with straight pin, on lock pin, be provided with the inclined-plane coordinating with straight pin.
For lock pin fast speed is dropped in dead bolt slide block limited impression, described lock pin is away from being provided with lock pin stage clip between one end of dead bolt slide block and housing.
For convenience of the installation of lock pin, on described housing, be provided with lock pin cover plate, described lock pin stage clip is arranged between lock pin and lock pin cover plate.
The beneficial effects of the utility model: by lock pin, arm of action, collar and be arranged on the dead bolt slide block limited impression combined action on dead bolt slide block, make when lock core is when extracting out in lock housing, lock pin falls in dead bolt slide block limited impression, stop the rotation of dead bolt slide block, dead bolt can not be retracted, still locked tubing string, plays antitheft effect.Prevented that stealer from using instrument lock core is taken out, stolen the possibility of vehicle.Further promoted the anti-theft effect of automobile.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the perspective view of the inner annexation of the utility model.
Fig. 2 is explosive view of the present utility model.
The specific embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of automobile ignition switch theft-prevention structure, comprise housing 12, be arranged on the igniting lock core 1 of housing 12 ends, on igniting lock core 1 and housing 12 counterfaces, be provided with collar 2, coordinate the fixed block 4 that rotates and connect the arm of action 5 of rotation with fixed block 4 with igniting lock core 1, arm of action 5 coordinates the dead bolt 10 that control and dead bolt slide block 11 link to stretch with dead bolt slide block 11; One end diameter that arm of action 5 coordinates with fixed block 4 is greater than one end that arm of action 5 coordinates with dead bolt slide block 11; Between one end that described arm of action coordinates with fixed block 4 and housing 12, be provided with arm of action stage clip 6, above dead bolt slide block 11, be also provided with lock pin 7, lock pin 7 is pressed on dead bolt slide block 11, on housing 12, be provided with lock pin placement hole 13, on dead bolt slide block 11, be also provided with the dead bolt slide block limited impression 14 coordinating with lock pin 7, dead bolt slide block limited impression 14 at ignition lock during in LOCK shelves and lock pin 7 in same plane.Between lock pin 7 and collar 2, be provided with straight pin 3, on lock pin 7, be provided with the inclined-plane 71 coordinating with straight pin 3.Described lock pin 7 is provided with lock pin stage clip 8 away from one end and 12 of the housings of dead bolt slide block 11.Preferably, lock pin 7 is installed for convenience, on described housing 12, is provided with lock pin cover plate 9, described lock pin stage clip 8 is arranged between lock pin 7 and lock pin cover plate 9.
Principle of work of the present utility model: when igniting lock core by people when taking out in housing, arm of action is under the spring-force driven dual of arm of action stage clip, direction along igniting lock core moves, and drives fixed block and collar along igniting lock core direction, to move together, and now straight pin is separation with collar.When arm of action moves, dead bolt slide block same-action bar moves together, make dead bolt slide block limited impression move to the below of lock pin, lock pin moves downward under the effect of lock pin stage clip, fall in dead bolt slide block limited impression, simultaneously, because the other end of straight pin does not stress, therefore straight pin moves along igniting lock core direction under the effect on lock pin inclined-plane, guarantees that lock pin is not subject to the resistance of straight pin, drops in dead bolt slide block limited impression smoothly, the rotation of resistance dead bolt slide block, make not flexible of dead bolt, continue to be stuck in steering column, play antitheft effect.
