Description

A kind of theftproof lock of telescopic turning-bolt lock core

Technical field:

The utility model relates to a kind of theftproof lock, more particularly, relates to a kind of motorcycle, electric motor car, bicycle and theftproof lock that be provided with telescopic turning-bolt lock core.

Background technology:

The utility model is mainly the anti-theft lock structure of motorcycle, electric motor car, bicycle, existing theftproof lock be not can be cut off, sawed-off, can be opened, prize bad exactly by strand or by technical unlocking, specifically exist defective following for example: 1. lock body is not strengthened through quenching, keyhole is unhidden, lock core does not dally, and can be cut saw, strand sled or technical opening by violence; 2. lock body is strengthened through quenching, but keyhole is unhidden, lock core delocalization idle running, can be by violence strand sled or technical opening; 3. lock body is strengthened through quenching, Lock cylinder idling, but keyhole is unhidden, and can be by violence strand sled or technical opening; 4. keyhole is hidden, but lock body is not strengthened through quenching, lock core does not dally, and can be cut saw by violence, strand is pried open and opened; 5. Lock cylinder idling, keyhole is hidden, but lock body strengthens through quenching, and can be cut to cut by violence and open; 6. Lock cylinder idling, but keyhole is unhidden, lock body is strengthened through quenching, and can be cut saw sled or technical opening by violence.

In May, 2006, on unblank ring in Zhengzhou City, Henan Province 500,000, several key sign indicating number locks have only been used just easily opened several seconds by the locksmith, the defective of these locks is that keyhole is exposed to outward, lock core does not dally, finally cause being twisted out by unlocking tools such as so-called master keys, as seen the lock that has good theftproof performance needs the firm degree of lock core internal construction, lock body external structure and lock body itself all can reach good anti-theft effect.

And as above example 5 is described, existing Lock cylinder idling, keyhole is hidden, but the theftproof lock that lock body is not strengthened through quenching has been a lock preferably, if can carry out quenching strengthening to lock body handles, its anti-theft effect will be better, but, it leaves other future trouble also: this structure of one is because the unrestricted delocalization idle running of lock core 360 degree, and not playback point prompting, so under the effect of external force, keyhole can be in lock pipe generation annular or vertical shift, make the key of lock itself also can put to enter or only can put into the some in the keyhole, seek correct key eye position to the user and bring very big trouble, quite owe practical; Its two this structured lock core adopts tensioner mode and lock body relative fixed, and without any the alignment restrictions structure, this brings many future troubles also for use thereafter: or tensioner too, make this structure lose the effect of idle running, or dally severely, jolting and also can allow keyhole produce displacement in top in feasible the enforcement, and is difficult for return, and this also brings very big inconvenience to use.

The characteristics of comprehensive above-mentioned present existing motorcycle, electric motor car, anti-theft lock for bicycle can draw these locks and remain the perfect not to the utmost antitheft weakness in many places, so that can't reduce the quantity that vehicle is lost in the society, are difficult to solve the problem that people's vehicle is lost.
