By the application number of applicant application be 96102396.1, name is called " anti-picking lock for vehicle ", be disclosed in the patent application on December 11st, 96, and the anti-picking lock for vehicle that provides for 95224346.6 patent application of application number, owing between pin-and-hole and the pin-and-hole spacing is arranged, can cause locking inconvenience sometimes.

This is carried out later-model purpose and provides a kind of new anti-picking lock for vehicle, to overcome the deficiency of above-mentioned lock, makes locking convenient.

The purpose of this utility model realizes by following mode.

There is a spill of keeping off installation outward to coil outward, coils outward in the protruding sidewise tapered end in top and be provided with pin tumbler lock body, also be provided with outer dish pin-and-hole near axletree.Be provided with the pellet shot from a slingshot core in the pin tumbler lock body, there is one the lock pin of continuous action relation to be arranged in the outer dish pin-and-hole with the pellet shot from a slingshot core, there is a main body to be positioned at the recessed inner disc of the outer dish of spill, inner disc is fixed on the axle skin of vehicle axles, and have and the cooresponding inner disc pin-and-hole of lock pin, lock pin is made of last joint and following joint, and a recoil spring is arranged therebetween.

Anti-picking lock for vehicle according to the utility model provides can improve the comfort feature of locking effectively, promptly no matter whether lock pin is corresponding with lockpin hole, and locking easily.

Below in conjunction with accompanying drawing the utility model is described in detail:

Accompanying drawing 1 is to be installed in structural representation on the rear axle assembly for bicycle according to the anti-picking lock for vehicle that the utility model provides.

Accompanying drawing 2 is structural representations of lock pin in the accompanying drawing 1.

As shown in drawings: have one to keep off the spill of (23) installing outward near axletree and coil (2) outward, coil outward and be provided with pin tumbler lock body (4) in the protruding sidewise tapered end in top (3), also be provided with outer dish pin-and-hole (6).Be provided with pellet shot from a slingshot core (5) in the pin tumbler lock body, there is one the lock pin (7) of continuous action relation to be arranged in the outer dish pin-and-hole (6) with pellet shot from a slingshot core (5), there is a main body to be positioned at spill and coils (2) recessed inner disc (1) outward, inner disc is fixed on the axle skin (24) of vehicle axles, and have and the cooresponding inner disc pin-and-hole of lock pin (7) (8), lock pin (7) is by last joint (71) and save (72) formation down, and a recoil spring (162) is arranged therebetween.

Lock pin also is provided with spring (161) on the joint (72) down, and the elastic force of recoil spring (162) is greater than the elastic force of lock pin lower springs (161).

Press joint (71) on the lock pin when needing the lock car, joint (72) is through in the inner disc pin-and-hole (8), or with the core (5) of key turns spring lock, joint (72) is through in the inner disc pin-and-hole (8), because the outer dish sidewise tapered end of (2) epirelief (3) is to stretch out from cycle frame neutral gear position, is blocked by vehicle frame, outer dish can not rotate, inner disc (2) is fixed on again on the waggon axle skin (24), and therefore axle skin (24) and wheel can not rotate.With the core (5) of key turns spring lock, the pin-and-hole (8) that joint (72) breaks away from the inner disc under the lock pin is got final product in the time of need unblanking.

As shown in drawings: when lock pin moves down locking, when if lock pin saves (72) with pin-and-hole (8) dislocation down, spring (162) shrinks, joint (71) is located by core (5) on the lock pin, as long as rotating-wheel, joint (72) and lockpin hole (8) are at once under lock pin, and recoil spring (162) opens, and lock pin is saved (72) down be pressed in the lockpin hole (8); When unblanking, joint (71) breaks away from the control of core (5) on the lock pin, and spring (161) opens, and lock pin is joint (72) down, moves separating lock pin-and-hole (8) on the joint (71) on the lock pin, promptly opens.
