Description
The utility model relates to lock class technical field, particularly a kind of anti-theft lock for bicycle.
More existing anti-theft lock for bicycle, adopt independently lock body and locking bolt, the bolt-stopping sleeve that U-shape lock body two ends are fixed with the band step through-hole that is used for guide gip respectively and are used for ending bolt and are provided with alignment pin is finished the locking or the breakdown action of lock body and locking bolt by the lock-opening mechanism that lock core, pin tongue are housed.The anti-theft lock for bicycle of this class formation is because lock body and locking bolt split will look for the place to deposit locking bolt after the unlatching, or locking bolt left in be loaded on depositing in the cover on the back fork of bicycle another location, or leave locking bolt in be connected deposit in the bolt cover with lock body, for the user, operate very inconvenient.
The anti-theft lock for bicycle that provides a kind of locking bolt and lock body assembly elasticity to link into an integrated entity is provided the purpose of this utility model, it is not only simple in structure, firm, and can be without key one-handed performance automatic blocking, after unblanking, locking bolt is from moving from bolt-stopping sleeve, and it is also very convenient to deposit lock.
The purpose of this utility model is achieved in that a kind of anti-theft lock for bicycle, comprises the U-shape lock body, the locking bolt of the lock-opening mechanism of being made up of tapered end, dead bolt is housed, and lock body one end is fixed with bolt-stopping sleeve, and the U-shape lock body other end is hinged with movable bolt cover; Locking bolt and movable bolt cover elasticity link into an integrated entity; Be respectively equipped with a through hole and alignment pin in the movable bolt cover, its front end is provided with only circlip; Locking bolt is the two-stage cylinder, and back level is equipped with lock-opening mechanism, behind the locking bolt level with the alignment pin correspondence position of bolt cover on have the axial location groove, behind the pin level front end with only between the circlip back-moving spring is housed.Overlap at movable bolt on the lock body of a side and be fixed with fixed bolt fork.
Advantage of the present utility model is simple in structure, firm, and theftproof performance is good, locking, unblank, solid locking bolt is all very convenient, fast.
Fig. 1 is the structural representation of an embodiment of the utility model, is locking states herein.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1, removes locking bolt herein.
Fig. 4 is that the A of Fig. 1 is to view.
Fig. 5 is that theftproof lock shown in Figure 1 is in the structural representation of opening and depositing under the bolt state.
By following embodiment the utility model is further elaborated.
Referring to Fig. 1-shown in Figure 5, the U-shape lock body 1 usefulness 14mm square steel of present embodiment curves, and lock body 1 one ends are welded with bolt-stopping sleeve 2, and the other end is hinged with movable bolt cover 7 by hinge axis 11 and hinge seat 10, and hinge seat 10 is affixed for welding with movable bolt cover 7.Movable bolt overlaps 7 front ends and is fixed with only circlip 4, and movable bolt overlaps 7 tops and has a through hole 8 bigger slightly than dead bolt 9 diameters, overlaps 7 inside walls at movable bolt one alignment pin 13 is housed.Locking bolt 3 is the two-stage cylinder, and back level is equipped with lock-opening mechanism, and it is made up of lock core 14 and dead bolt 9, and locking bolt 3 back levels have an axial location groove 6 overlapping on 7 alignment pin 13 correspondence positions with movable bolt.During installation, locking bolt 3 back grade front ends with only between the circlip 4 back-moving spring 5 is housed, dead bolt 9 and through hole 8 couplings, alignment pin 13 is stuck in the axial location groove 6, like this, just constituted locking bolt 3 and overlapped 7 elasticity with movable bolt and link into an integrated entity, locking bolt 3 only in axial location groove 6 effective lengths movable relatively bolt cover 7 do axial front and back displacement.During locking, locking bolt 3 front ends enter in the bolt-stopping sleeve 2 straight.
This theftproof lock is contained in the back fork of bicycle top, and operation is locked, opened to trailing wheel.When locking, one hand puts locking bolt 3 to level, guarantees that by axial location groove 6 and alignment pin 13 its front ends can push in the bolt-stopping sleeve 2 smoothly, and meanwhile, dead bolt 9 enters in the through hole 8 automatically, finishes the locking action.When unblanking, key inserts lock core 14, pull down dead bolt 9, make in its withdrawal locking bolt 3 bodies, at this moment, under back-moving spring 5 effects, locking bolt 3 is from moving from bolt-stopping sleeve 2, by hinge seat 10 locking bolt 3, movable bolt cover 7 are turned over 90 °, and locking bolt 3 rearward end are embedded in the fixed bolt fork 12 that is packed on the lock body, easy to operate, quick.
