Description

There is the tapered end of double opening lock function

Technical field

The utility model relates to a kind of tapered end, especially for the tapered end with double opening lock function of the vehicle anti-theft such as bicycle, two-wheeled motor vehicle steel cable lock.

Background technology

The common mode of unblanking of current tapered end can be divided into two classes: coded lock and key lock.Coded lock is unblanked by password character wheel to the correct coding rotated on tapered end, and without the need to carrying keys, and can change number of unblanking at any time, very convenient, secrecy is high, and safety is good; Key lock has cylinder lock and blade lock etc. multiple, cylinder lock head comprises lock core shell, can be rotatably set in the lock core in lock core shell and is arranged on the pellet group row between lock core shell and lock core body, each group of pellet group in lock forms by two pellets, during locking, the contact surface of two pellets does not overlap with the contact surface of lock core shell and lock core body, due to the barrier effect of pellet, lock core body can not rotate; When unblanking, insert the key matched, the contact surface of two pellets overlaps with the contact surface of lock core shell and lock core body, and lock core body can rotate relative to lock core shell and unblank.Padlock head is made up of following component substantially: the lock core of tubular and lock core shell, some blades, some ring shaped baffle and side column.Blade edge be provided with side column diameter compatible but position and the different half round cut of angle, centre is provided with key hole, and blade is alternate with partition is placed in lock core.Lock core barrel is provided with the axial long slot bore matched with side column, and lock core is arranged in lock core shell rotationally together with partition, blade etc., and lock core shell inwall and long slot bore relevant position are provided with the side column groove matched with side column, and side column is placed between long slot bore and side column groove.Before unblanking or insert non-matching key time, the half round cut on lock core tube intra vane is out of line, and side column is still between long slot bore and side column groove and blocks lock core, makes lock core cannot rotate and keep locking not busy state; When inserting matched key, the half round cut on all blades will be in straight line and relative with long slot bore position, and side column falls between long slot bore and breach, and disengaging side column groove, now lock core can rotate thus be opened by lock under the drive of key.And puzzle lock generally includes password lock tube, coded lock plug and by elastic wheel, the cipher wheel assembly that ring-type locating wheel and ring-type cipher wheel are formed, coded lock plug one end is fixed on the end of wirerope, locating wheel and reed seat wheel phase poststack are arranged on after in cipher wheel and are together set in password lock tube, wherein locating wheel and cipher wheel circumference are located by connecting, reed seat wheel is located by connecting with password lock tube circumference, the surface of password lock tube is along axle being established spaced projection, interval location and width and locating wheel match, coded lock plug cross section and coded lock pipe orifice match, the surface of coded lock plug is along axle being established spaced projection, interval location and width and locating wheel match and make it can take turns together with cipher wheel and reed seat to rotate, coded lock tube wall is provided with the protruding gap with above-mentioned coded lock plug vertically and matches grooving, reed seat wheel and locating wheel inner ring are provided with the breach matched with coded lock plug projection, when all cipher wheel rotate to breach in alignment and with grooving position consistency time, namely coded lock plug can be transferred to from password lock tube thus lock is opened.Two classes locks cut both ways, and blade lock or key lock are opened convenient and swift, if but leave behind key or key and lose and just cannot unblank; Coded lock does not have key, is not therefore afraid of loss, if but forget Password and just cannot unblank equally.
