As long as being stealer, another problem provides remote controller of the same type for oneself, the control box that comprises signal access device, decoder, control circuit, pry open after the vehicle enclosure and line stretcher piece of the same type and former fare road to be patched piece achieve a butt joint, press the remote controller that carries again, the decoder that then carries impels machine operation, realization is unblanked, thereby steals car.

The objective of the invention is to overcome above-mentioned defective, a kind of anti-detaching theft-proof electric door lock is provided.

The invention scheme: the lock body shell extends two bolt blocks, one open-work is respectively arranged on each bolt block, the relevant position is provided with catch above screw, this catch is screwed on the lock body shell and inserts in the corresponding bar shaped seam of lock body, the outer catch of bar shaped seam partly covers above bolt, extend " returning " shape square hole by the corresponding bar shaped seam of lock body shell periphery simultaneously, the end face retaining of square hole top is above catch, catch stretches in the bar shaped seam on the part and lock pin fixing screens sheet and forms additional lock, decoder, control circuit, lock body is inclusive in the lock cover, the lock cover has the horizontal rectangular box of rectangular opening for the bottom, rectangular opening passes lock pin at the lock cover end, and its both sides are pressed under the lock body.

The invention has the advantages that catch can stop stealer to take vehicle enclosure apart lock bolt body is dismantled, simultaneously decoder and control circuit are installed in and have also stoped other people to provide decoder for oneself in the lockset box to be started with by the line stretcher piece and unblank, lockset safety is greatly improved.

Description of drawings: Fig. 1 is a structural representation of the present invention.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 1.

Fig. 4 is the C-C sectional view of Fig. 2.

The specific embodiment: this lockset is made up of crank mechanism, lock pin (1) in remote controller, signal receiving device, decoder (2), control circuit (4), motor, reducer, the lock body (5).The decoding back rotates motor driving reducer, crank mechanism by control circuit (4), force lock pin (1) translation, lock pin (1) translation then can be inserted the screens of vehicle steering shaft lockhole and be played antitheft effect, and the ignition switch that crank mechanism also can be controlled electric switch simultaneously is switched on or switched off.
