Abstract
The utility model relates to a plunger type bicycle lock. A lock core is arranged in a tubular lock body of which one end is sealed through a stator on which a through hole corresponding to the marble hole of the lock core is also arranged, and the other end of the lock core is provided with a bar-shaped groove of which the outer end is provided with a lock bolt fixed on the inner side of the lock body and provided with a bar-shaped through hole corresponding to the bar-shaped groove. One end of a column-shaped lock beam is provided with a bar-shaped convex edge, and a marble and a spring are arranged in the marble hole communicated with the stator and the lock core. An unlocking upright post is fixedly arranged on a circular key, and a lock tank fixed on the back fork of a bicycle is also sheathed on the lock beam. The utility model has the advantages of simple structure, convenient installation and use, good anti-prizing performance, etc.
Description
The utility model belongs to technical field of bicycles, particularly a kind of cable brake bicycle lock.
Present cable brake bicycle because the lock hand is installed in the back vent place, makes the common crab shape lock can't normal mounting, carries if use the then not only dangerous but also inconvenience of soft lock instead.Recently occur a kind of rotary steel rod lock on the market, though can be installed on the back vent of cable brake car, following shortcoming is arranged: there is lock bridge import breach in (1), lock storehouse, and pick-proof intensity is impaired; (2), lock core is thinner, anti-torsional strength is low; (3), a little less than erection bolt and the rotating mechanism pick-proof ability.
The purpose of this utility model provides a kind of plunger type bicycle lock of being convenient to be installed on the cable brake bicycle.
The purpose of this utility model is achieved in that it comprises lock body, lock bridge, key, it is characterized in that at one end being provided with in the tubular lock body by the stator sealing one vertically at least with the lock core in two pellet shot from a slingshot holes, on stator, also have and the corresponding through hole of lock core marble hole, the other end at lock core has a strip groove, be provided with one to be fixed on lock body inboard and have a dead bolt with the corresponding strip through-hole of bar-shaped trough in the outer end of groove, being provided with one at cylinder locks one end can insert dead bolt and can embed the bar shaped fin that drives its rotation in the strip groove, in the pellet shot from a slingshot hole that stator is connected with lock core, be provided with pellet shot from a slingshot and spring, on round key, be fixed with and insert in the stator through hole and make pellet shot from a slingshot, also be with a lock storehouse that is fixed on the bicycle back fork on the lock bridge with being located away from the unlocking column stand on plane between stator and the lock core.During use, earlier lock body and lock storehouse are fixed on two bicycle back forks, during the lock car lock bridge is passed dead bolt and the fin on it is embedded in the lock core strip groove, after driving position of lock core rotation, pellet shot from a slingshot hole and through hole in lock core and the stator communicate, and make pellet shot from a slingshot be subjected to spring in the through hole under the elastic force effect of spring, and this moment, lock core can't rotate, this moment, the bar shaped fin on the lock bridge misplaced with the strip through-hole on the dead bolt, made it can't extract then car and was locked.When needs are unblanked, as long as unlocking column stand that will be on the key turns back in the stator through hole again, make pellet shot from a slingshot be located away from plane between stator and the lock core simultaneously, then lock bridge drives lock core and rotates back into original position, can extract lock bridge lock is opened.
The utility model has fundamentally solved the problem that it is difficult that the cable brake car is locked, but also have simple in structure, easy to install, characteristics such as the pick-proof performance is good.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a lock body part user mode structural representation of the present utility model.
Fig. 2 is a lock of the present utility model storehouse part-structure schematic diagram.
By shown in Figure 1,1 is the tubular lock body, in lock body 1, be provided with one vertically with the lock core 5 in five pellet shot from a slingshot holes, be closed with a stator 2 that has a corresponding pellet shot from a slingshot through hole at an end of lock body with lock core marble hole, in the pellet shot from a slingshot hole that stator communicates with lock core, be provided with pellet shot from a slingshot 6 and spring 7, the other end at lock core has a strip groove, be provided with one to be fixed on lock body inboard and have a dead bolt 11 with the measure-alike strip through-hole of strip groove in the outer end of groove, is provided with one at an end of cylindricality lock bridge 12 and can passes dead bolt and embed the fin 10 that drives its rotation in the strip groove.On disc key 3, be fixed with the unlocking column stand 4 that can insert stator through hole varying length.On lock bridge, also be with a lock storehouse 13, tubular lock body and lock storehouse respectively by U-shaped lock hang 8 and the screw fixed cover on two back vents 9 of bicycle, and lock body is concentric with the lock storehouse.During the lock car, lock bridge is passed lock storehouse, dead bolt and fin is embedded in the lock core strip groove, after driving angle of lock core rotation, pellet shot from a slingshot hole and through hole in lock core and the stator communicate, make pellet shot from a slingshot under the effect of spring, spring in the through hole, lock core can't rotate, owing to rotated certain angle the through hole of fin and dead bolt on the lock bridge is misplaced, make it can't extract then car and locked; When need were unblanked, by above-mentioned reverse operating, then lock was opened.
