Description

Fixed steel wire lock

The utility model relates to and a kind ofly is fixedly mounted on the vehicle frame of bicycle saddle below or the fixed steel cable lock on the front-wheel front forked frame.

At present, widely used bicycle steel cable lock, the advantage of this class lock is: lock body generally all adopts integral metal material or other firmer nonmetals to manufacture, has good pick-proof and anti-theft performance, its wirerope part is also firmer, generally speaking, there is not special tool(s) to be difficult at short notice with its destruction.Preferable is that it can lock together bicycle and other fixed object, as big tree of iron railing or the like, but because this class lock is not to be fixedly mounted on a certain permanent position of bicycle, therefore in use increased trouble, how to remove this trouble from, also to intactly keep and strengthen its original performance simultaneously, just constitute the purpose of this utility model.

To achieve these goals, the clamp that an additional energy and bicycle rack connect smoothly on the lock body of the utility model steel cable lock in the prior art, simultaneously the lock body external form of steel cable lock is made the shape that combines with clamp of being more convenient for, by bolt and nut clamp and lock body are fixed on the side (front-wheel part or trailing wheel part) of bicycle rack, at corresponding vehicle frame opposite side with it a lock pin body circulator that is used to place the lock pin body are installed simultaneously.Simultaneously lock pin is suitably extended, make it can pass the width of cloth bar and the lock body locking of wheel by circulator, circulator can also play the effect of reinforced lock shank simultaneously, strengthened theftproof performance, below in conjunction with specific embodiment, to the utility model--the technical characterictic of fixed steel cable lock is described in further detail.

Accompanying drawing 1 is the utility model---the structural representation of fixed steel cable lock.

Accompanying drawing 2 and accompanying drawing 3 are respectively A-A sectional view and B to view.

With reference to the accompanying drawings 1,2,3, the utility model one fixed steel cable lock is mainly by lock body, the fixing card of lock body, lock pin body circulator, the fixing card of lock pin body circulator, and lock pin body and wirerope are formed.Lock body 1 has the fixing card of two bolts hole 2 and lock body 5 to be fixed on bicycle rack 6(rear wheel frame or the front-wheel front forked frame by bolt and nut 3,4) drive dead bolts 9 by key 7 rotation lock cores 8 and move up, pressuring spring 10 is finished the task of unblanking, and spring 11 ejects lock pin head 13 with spring compressor 12 in lockpin hole 14 simultaneously.On lock body 1 upper left side one circular hole is arranged vertically, insert wirerope head 39 and use short pin 40 to fix, its top is with a sheath 41, prevents that rainwater from entering lock body.

Lock pin body circulator is by front pressuring plate 15, rear fender 16, and lock pin body bearing pin 17, steel wire card 18, locking pellet shot from a slingshot 19, rear fender boss 20, spacer pin 21, safety plug 22, Spring Card 23, guard ring 24 constitutes.By the fixing card 25 of lock pin body circulator, bolt, nut 26,27 are fixed in lock pin body circulator and lock body 1, on the corresponding bicycle rack iron pipe 28, lock pin body bearing pin 17 is a cylinder, the big slightly end of one diameter 29 is arranged, its circumferential section has a plane 30, contact with steel wire card 18, when lock pin body bearing pin 17 radially rotates owing to will overcome the elastic force of steel wire card 18, therefore form feel, be convenient to the location.Steel wire card 18 two ends are fixed on 16 two circular holes 36 of rear fender.Lock pin body bearing pin 17 radially has a through hole 31, is used to place lock pin body 38, and lock pin body 38 is a round iron pipe, and the groove pressing on wirerope 34, one ends and the lock pin head 13 is passed at the center, and the other end is equipped with one handle 37.Lock pin body bearing pin 17 center one side vertically has a through hole 32 to be used for placing locking pellet shot from a slingshot 19, the position diameter that this through hole communicates with through hole 31 is slightly a little bit smaller, when lock pin body 38 is all extracted in through hole 31, locking pellet shot from a slingshot 19 can not drop out in hole 32,29 places, end at lock pin body bearing pin 17, its center of circle part has a circular hole 33, to cooperate rear fender boss 20, make lock pin body 38 when the upright position, boss 20 compressing locking pellets shot from a slingshot 19 are with 38 lockings of lock pin body, prevent lock pin body play up and down, so since the position of boss 20 and locking pellet shot from a slingshot 19 all in a side of the axial centre of lock pin body bearing pin 17 when lock pin body 38 rotates to horizontal level together with lock pin body bearing pin 17, locking pellet shot from a slingshot 19 no longer is subjected to boss 20 compressings, locking pellet shot from a slingshot 19 is no longer locked lock pin body 38, and lock pin body 38 advances in lockpin hole 14 smoothly, and lock pin head 13 is entered in the lockpin hole 14, promote spring compressor 12 pressuring springs 11, cooperate dead bolt 9 to finish locking.The effect of spacer pin 21 is to cooperate safety plug 22 to prevent that lock pin body 38 from swinging, and safety plug 22 and steel wire clamp 23 can move forward and backward by front pressuring plate 15 rear fenders 16, play safety effect, prevents from by bike the time to make the lock pin body break wheel width of cloth bar because of fortuitous event.When needs are walked around thing (the iron railing of interlocking as long as lock pin body 38 extracted out in the lock pin body bearing pin through hole 31 during with bicycle and other fixture (iron railing, big tree etc.) interlocking, big tree etc.) pass lock pin body bearing pin through hole 31 again, insert lockpin hole 14, finish interlocking.

The utility model structure is ingenious, and is easy to use, so be particularly suitable for as bicycle lock.
