Difunctional horseshoe lock
Technical field
The utility model relates to a kind of lockset, especially for the difunctional horseshoe lock of bicycle.
Background technology
Standard bicycle with horseshoe lock usually by lock housing, be provided with the lock ring of locking gap, ball lock head and stop mechanism, extension spring, parts such as spanner are formed, extension spring, lock ring is slidably disposed in the lock housing, extension spring one end is fixed, the other end is connected with the inboard tail end of lock ring, lock housing is provided with guide chute, spanner one end passes guide chute fixedlys connected with lock ring, drive lock ring as long as press lower ejector lever along guide chute, the opening that makes the lock ring front end stride across lock housing enters the opposite side of lock housing, at this moment stop is stuck in the breach on the lock ring, the lock ring closure can't be opened reach the purpose of locking; Make stop break away from breach on the lock ring when inserting key unlocking, at this moment lock ring is withdrawn into and reaches the purpose of unblanking in the lock housing under the effect of tension spring tension.At present, the horseshoe lock of the overwhelming majority all is to adopt cylinder lock, cylinder lock head is by being arranged on the rotation that pellet shot from a slingshot group between lock core shell and the lock core body is listed as to lock lock core body, the pellet shot from a slingshot group of respectively organizing in the lock is formed by two pellets shot from a slingshot, during locking, the contact surface of two pellets shot from a slingshot does not overlap with lock core shell and contacting of lock core body, because the barrier effect of pellet shot from a slingshot, lock core body can not rotate; When unblanking, the key that insertion matches, the contact surface of two pellets shot from a slingshot overlaps with the contact surface of lock core shell and lock core body, lock core body can rotate and unblanks relative to lock core shell, horseshoe lock also has part to adopt coded lock, coded lock comprises coded lock lock head component and password stop, the coded lock lock head component generally includes the coded lock pipe, retainer plate, floating ring, the ring-type cipher wheel, the ring-type locating wheel, ring-type reed seat wheel and reed, locating wheel and reed seat wheel phase poststack are arranged in the cipher wheel, wherein locating wheel and cipher wheel circumferentially are located by connecting, reed seat wheel circumferentially is located by connecting with the coded lock pipe, when all cipher wheel rotations are extremely correct, thereby password stop disengagement lock ring is opened lock.Two classes locks cuts both ways, and blade lock or cylinder lock are opened convenient and swift, if but leave behind key or key and lose and just can't unblank; Therefore coded lock does not have key, is not afraid of loss, if but forget Password and just can't unblank equally.
