Description

The self-propelled vehicle puzzle theft-proof lock

A kind of self-propelled vehicle accessory device of technical field, the particularly pre-stolen lockset of anti-vehicle.

Door Lock on the background technology current mobility car, Circuit lock, the curved handle lock of umbrella all open the lock with the key, and are easy to be overlapped the core of unblanking by the burglar, and car is stolen.Occur a kind of central door lock with computer chip control in recent years, the price eighteenth of the twenty is expensive, is not suitable for general self-propelled vehicle.

The summary of the invention the purpose of this utility model provides a kind of self-propelled vehicle puzzle theft-proof lock, accomplishes directly to pin bearing circle, and is simple and reliable for structure, and safety performance is good, and cost of manufacture is low.

First technical scheme is the lock gear ring with 3～5 teeth that is mounted between vehicle directional drive link and direction drive link cover on the direction drive link, or on the direction drive link, get out with being evenly distributed 3～5 the lock perforations, lock body and chimeric with it combination lock body are fixed on the direction drive link and put, locking bar on the lock body passes the direction drive link and puts the lockhole top between two adjacent lock teeth or in the lock perforation, there are three oblong pintle hook locks at the locking bar middle part and are with three digit wheels, have on each digit wheel inner ring and the corresponding breach of pintle hook lock size, there are position-limited trough and position-limited lever in the locking bar rear portion, unblank in addition and two lock bolt jacks of locking, the locking bolt of being stirred by lock cylinder commonly used can insert in the lock bolt jack.

Using method and principle of work are as follows: during blocking, locking bolt is inserted in the locking lock bolt jack, and three pintle hook locks lay respectively at three digit wheel left sides, and locking bar can not be drawn out.The locking bar top is between two adjacent lock teeth or in the lock perforation, the direction drive link can not rotate.Unblank if desired, at first rotate three digit wheels, make three digit wheels show preset password, even the breach on three digit wheel inner rings is aimed at three pintle hook locks on the locking bar respectively, with the key rotary locking cylinder locking bolt is withdrawed from from the locking lock bolt jack then, pull out locking bar and realize unlocking condition.At this moment the limited bar of the other end of position-limited trough blocks, locking bar can not continue to pull out, and locking bolt is inserted in the lock bolt jack of unblanking, and three pintle hook locks pass three digit wheels respectively and are positioned at the digit wheel right side, lock tooth or lock perforation are left in the locking bar top, and the direction drive link can freely rotate.Locking if desired, at first, with key rotation lock core locking bolt is withdrawed from the lock bolt jack of unblanking then, locking bar is advanced in lock body the password of three digit wheels, suitably rock the direction drive link, the locking bar top is advanced between two adjacent lock teeth or the lock perforation in.No matter unblank or locking, all will transfer random numerical code after operation is finished, in order to avoid reveal password.

Second technical scheme and such scheme are basic identical, difference is to change the digit wheel control mechanism, be that the locking bar middle part is the triangle pintle hook lock, secondary locking bar square crossing is installed on the locking bar, and pintle hook lock is positioned at the half slot at secondary locking bar middle part, and four digit wheels are distributed in secondary locking bar both sides, the pin that four protrusions are arranged on the secondary locking bar, have respectively on each digit wheel and the corresponding groove of unblanking of pin, an end of secondary locking bar has position-limited trough and position-limited lever, and the other end has pull back spring.The spring of unblanking is housed on the locking bar.

The operational version and the principle of work of second scheme are as follows: locking bolt is inserted in the locking lock bolt jack during blocking, the triangle pintle hook lock is blocked by secondary locking bar, locking bar can not be turned right and be stretched out, and the locking bar top is between two adjacent lock teeth or in the lock perforation, the direction drive link can not rotate.Simultaneously, the pin on the secondary locking bar is blocked by digit wheel with it, and secondary locking bar can not be rotated.Unblank if desired, at first rotate four digit wheels, make four digit wheels show preset password, even the groove of unblanking of four digit wheels is aimed at four pins on the secondary locking bar respectively, under the control of position-limited trough and position-limited lever, can only rotate 60～70 ℃ with hand revolute pair locking bar this moment, spacing purpose is that pintle hook lock can not still be in it and pay in the locking bar half slot toward moving right too much.With the key rotary locking cylinder locking bolt is withdrawed from from the locking lock bolt jack simultaneously with it, then past valve body right side displacement under the effect of the spring of unblanking of locking bar realizes unlocking condition.Lock tooth or lock perforation are left in this hour locking lever top, and the direction drive link can freely rotate; Under the effect of pull back spring, secondary locking bar abuts against pintle hook lock drift angle place, makes the pintle hook lock displacement of no longer turning right.Locking if desired, as long as locking bolt is withdrawed from from the lock bolt jack of unblanking with key rotation lock core, at this moment under the pull back spring effect, the half slot of secondary locking bar promotes pintle hook lock, force locking bar toward moving left, suitably rock the direction drive link, make the locking bar top between two adjacent lock teeth or enter lock and get final product in the perforation.Compared with the prior art, characteristics of the present utility model are directly to pin the direction drive link, unblank to use key and password simultaneously, and as safe as a house reliable, theftproof performance is good, and productive costs is low, and is applied widely.
