Description

The double insurance bicycle lock

The utility model relates to a kind of pipe lock, particularly a kind of bicycle lock.

Common bicycle pipe lock shown in the accompanying drawing case, comprises lock body 5, lock bridge 7, lock pipe 6 etc., and it is provided with breach and places compression spring 1, one end and brake handle 15 is set comes the open and close lock on lock bridge 7.Among the figure, the 2nd, lining, the 3rd, the tapered end overcoat, the 4th, locking bolt, the 8th, little lock bait, 9 ' be the lock mouth, the 13, the 14th, pin, the 17th, lock bait greatly.The bicycle lock of this traditional structure, because lock bridge 7 single books, the robber easily cuts, easily saws, easily prizes, so theftproof performance is relatively poor.If the diameter that increases lock bridge 7 strengthens the rigidity of lock bridge, during production the arch lock bridge 7 that increases to be inserted in the arch lock pipe 6, its process aspect is difficult to realize.

The purpose of this utility model is at above-mentioned deficiency, proposes a kind of double insurance bicycle lock, and it has improved the lock bridge structure on original bicycle lock basis, makes it have the double anti-theft performance.

The utility model comprises arch hollow lock pipe, lock bridge, lock body, compression spring, handle etc., and lock bridge is a whole arcuation section bar, and lock bridge one end is equipped with protecting tube, and the other end is equipped with decorates pipe; Compression spring is nested with on lock bridge and places in the arch hollow lock pipe, and the one end is fixed on the interior lining of lock pipe, and the other end is butted on shutoff place of decorating pipe.

The utility model has improved the structure of lock bridge on the basis that does not change original bicycle lock structure, make its forward and backward two ends be equipped with protecting tube respectively, decorate pipe, has strengthened the stiffness of lock pipe, has more anti-sled performance.Because lock bridge adopts whole arcuation section bar, cut when lock suffers the robber, saw, when prizing, be equipped with protective jacket because of adding in addition, the robber is difficult to destroy; In addition, even destroyed protective jacket, decoration pipe or the handle of lock tube-surface, but because the lock bridge integral structure, lock still can keep blocking, and the robber still need could thoroughly destroy lock by another program, so this utility model has the double insurance function.

Now in conjunction with the accompanying drawings the utility model is further described:

Accompanying drawing 1 is an ordinary bicycle lock construction schematic diagram;

Accompanying drawing 2 is the utility model structural representations;

Accompanying drawing 3 is the utility model lock bridge structural representations.

Shown in accompanying drawing 2, accompanying drawing 3, the utility model comprises arch hollow lock pipe 6, lock bridge 7, lock body 5, compression spring 1 and brake handle 15 etc., lock bridge 7 is whole arcuation section bar, the one end is equipped with protecting tube 9, when lock was closed, lock bridge 7 rotated out exposed part and is lock bridge 7 and protecting tube 9 combination parts; Lock bridge 7 other ends are equipped with decorates pipe 16, and handle 15 is arranged on to be decorated on the pipe 16, and compression spring 1 is nested with on lock bridge 7, and an end is fixed in lining 2, and the other end supports shutoff 18 places to protecting tube 16.Wherein, the 3rd, the tapered end overcoat, the 4th, locking bolt, the 8th, little lock bait, the 13, the 14th, pin, the 17th, lock bait greatly.

Lock pipe 6 the right are provided with groove for locking, brake handle 15 motions when unblanking, brake handle 15, lock bridge 7 and decoration pipe 16 are provided with garden pin nail 14 and are connected, and compression spring 1 locking breach is set on lock bridge 7, compression spring 1 front end is provided with lining, the rear end is provided with stop pin 18 at decoration pipe 16 places, turn lock body 5 cores, utilize the pressure of compression spring 1 to make lock bridge 7 self-returns, promptly unblank; Otherwise mention brake handle 15, make lock bridge 7 turn to certain position, promptly lockable.

Left end is provided with protecting tube 9 protection (be locking after exposed parts) on the lock bridge 7, and protecting tube 9 is with that garden pin nail 10 and 11 is set being connected of lock bridge 7 is fixing, and protecting tube 9 exposes end face shutoff 12 is set, and improves hiding lock bridge 7.Right-hand member is provided with decorates pipe 16, both can play the effect of decoration, can play the effect of protection lock bridge 7 and compression spring 1 again.

Because during lock bridge 7 closures, its exposed parts is equipped with protecting tube 9, so this section diameter is bigger, has increased stiffness; Simultaneously, its lock bridge 7 adopts the double-decker form, even protecting tube 9 is destroyed, but lock bridge 7 open and close lock constructions are unaffected, and anti-theft effect is obvious.The handle 15 of lock also is to place on the decoration pipe 16 of lock bridge 7 in addition, and when handle 15 and 16 whiles of decoration pipe were destroyed, lock still can keep blocking, and was unlikely by pirate of the open.During assembling, lock bridge 7 inserted lock pipe 6 after, be nested with protecting tube 9 more respectively and decorate pipe 16, so, process aspect is achieved.
