Description

A kind of bicycle password head licence plate lock

Technical field

The utility model relates to a kind of lockset, specifically a kind of bicycle lock.

Background technology

At present, known bicycle lock is adopt dead bolt or chain locking wheel and make its method that cannot travel, and it is held is a little simple structure, and its shortcoming is that the recurrence rate of key is high, lockset function singleness, lock and easily cut off or pry open.

Summary of the invention

In order to overcome the deficiency of existing bicycle lock key recurrence rate height and lockset function singleness, the utility model provides a kind of bicycle password head licence plate lock, this bicycle password head licence plate lock not only possesses the function of existing lock, and there is the dual-use function that password adds key, make that the recurrence rate of unblanking is low is one of several ten thousand parts, mutual opening rate is almost nil, the positive all right Installation Mark board of lock housing, the bicycle management of convenient office, enterprise, school, community.

In order to achieve the above object, the solution that the utility model is taked is: a kind of bicycle password head licence plate lock, it comprises housing, lock core, lock bolt, key, lock bolt has the first cylinder, the second cylinder, horizontal stripe and pogo barrel, lock bolt groove is set on the second cylinder, the first cylinder and the second cylinder are fixed on horizontal stripe two ends, and pogo barrel is fixed on below horizontal stripe between the first cylinder and the second cylinder; Lock core rear end arranges lock core step, and seat dish groove is set on scrambler; Lock core is fixed on housing left side, scrambler is placed on the left of housing and after lock core, is enclosed within on the first cylinder, cipher buckle, the second torsion spring set are on axle one, axle one is fixed between the lock core step and scrambler in housing, snap close, the first torsion spring set are on axle two, axle two is fixed between the lock core eccentric shaft and the second cylinder in housing, and lock bolt inserts among two holes of housing; The first cylinder passes housing, cipher buckle, passes housing again, and the second cylinder passes housing simultaneously, the spring one end of pogo barrel insertion simultaneously, and the spring other end withstands housing; Snap close coordinates after lock core and with lock core, and cipher buckle one end coordinates with lock core with seat dish groove fit, the other end, and second torsion spring one end is close to housing, the other end is close to cipher buckle, and first torsion spring one end is close to housing, the other end is close to snap close; Switch scrambler makes seat dish groove alignment cipher buckle, and key inserts lock core and promotes cipher buckle one end disengaging lock core step, and the other end embeds in the dish groove of seat, turning clockwise key, lock core eccentric shaft drives snap close to depart from lock bolt groove, and under action of the spring, lock bolt rises, and lock is opened; Lock bolt is depressed into lower end, latch under the first torsion spring effect and embed in lock bolt groove, under the first torsion spring and the second torsion spring effect, disengaging seat, cipher buckle one end dish groove, the other end are got back to original position, snap close one end embeds lock bolt groove, the other end is got back to original position, and band movable lock core, key are got back to original position, extract key, scrambler freely rotates, and lock is in locking states.

During use, lock is arranged on bicycle headstock, and bicycle front fork deflection left 45 is spent to left and right and lock bolt is pushed into housing downwards, latches under the effect of rectangle stage clip and embeds lock bolt groove, and lock bolt can not turn to it before and after blocking bicycle front fork, will lock locking.While unblanking, first switch scrambler makes seat dish groove alignment cipher buckle, key is inserted to lock core and promote in the dish groove of cipher buckle embedding seat, then turning clockwise key, lock core drives snap close to depart from lock bolt groove, under action of the spring, lock bolt climbs away bicycle front fork, will lock unlatching.

This lock not only blocks bicycle front fork can not turn to it, and lock bolt is manufactured with two 10 millimeters of round steel and is difficult to cut off and pry open, adopting password to add after the dual-use function of key, make to unblank at the bottom of recurrence rate is one of several ten thousand parts, mutual opening rate is almost nil, and housing front also can Installation Mark board, conveniently office, enterprise, school, the management of community bicycle.
