The lock body is formed by integral casting of steels; a positioning lock is respectively arranged in holes on both ends; a separate component is composed of the locking head and the lock bolt; a long axial groove, a short axial groove and a radial groove are arranged on the component; when the lock is closed, the grooves on both ends respectively enter into the corresponding positioning pins and areclamped to achieve the purposes of anti-prizing performance, anti-sawing performance, anti-shearing performance and anti-smash performance. The utility model has the advantages of favorable intensity, anti-rust performance, long service life, reasonable structure and high theftproof performance. The utility model is suitable for installing on various bicycles.
Description
The utility model relates to a kind of anti-theft lock for bicycle, is fit to be installed on the various bicycles.
As everyone knows, existing bicycle lock has convenient, flexible advantage simple in structure, and theftproof performance is improving constantly, but, the weak point that existing bicycle lock exists is: lock housing is stamped to form by sheet iron, perhaps by allumen casting lock body, is easily pried open destruction by the robber; Locking bolt bends or makes with hollow steel pipe with interior round steel with 10 millimeters, is easy to be cut off by bolt clipper, and the intensity and the rigidity of whole lock are relatively poor, causes the stolen frequent generation of vehicle, and in addition, iron sheet and spring are easy to get rusty, and influence the application life of lock.
The purpose of this utility model is to overcome above-mentioned weak point and a kind of anti-theft lock for bicycle of providing.
Lock body of the present utility model is formed by the steel monoblock cast, one end has a through hole with the level, in be provided with the tapered end alignment pin, the other end has a blind hole, in be provided with the locking bolt alignment pin, locking bolt is made by round pin more than 14 millimeters, directly connect with tapered end, form an independent member, the tapered end top has an axial long detent, and the locking bolt front end has an axially short groove, communicate to groove with stem, after member inserted the lock body key, the groove at its two ends and each self-corresponding alignment pin blocked, and reached pick-proof, anti-saw, anti-ly cut, prevent the purpose of pounding.
The utility model does not get rusty, need not lubricate so be afraid of because of without the iron sheet punching out with save spring mechanism, have good intensity and rigidity, rational in infrastructure, theftproof performance good, the characteristics of long service life, be fit to be installed on the various bicycles.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing 1 is the utility model elevation
Accompanying drawing 2 is the utility model left view
Accompanying drawing 3 is tapered end of the present utility model, the schematic diagram of locking bolt member under locking states
Accompanying drawing 4 opens the schematic diagram that can extract out under the state for tapered end of the present utility model, locking bolt member at lock
With reference to Fig. 1,2,3,4, the utility model is made up of key (1), tapered end (2), tapered end alignment pin (3), round pin (4), lock body (5), locking bolt alignment pin (6), locking bolt (7), tight river (8), screw (9).Lock body (5) is fixed on vehicle frame, and an end of lock body (5) has a through hole with the level, inserts for tapered end (2), and the top is provided with and the tapered end rationed marketing (3) of lock body (5) interference fit in the hole in; The blind hole of the other end is inserted for locking bolt (7), the blind hole top is provided with the locking bolt alignment pin (6) with lock body (5) interference fit, pack into the afterbody of tapered end (2) of locking bolt (7), use round pin (4) riveted again, tapered end (2) top has an axial long detent (10), locking bolt (7) front end has an axially short groove (11), communicates to groove (12) with stem.
When closing locking, the member that tapered end (2) and locking bolt (7) are formed inserts from the through hole end of lock body (5), treats that the axial long detent (10) of tapered end (2) top enters tapered end alignment pin (3); When the axial short groove (11) of locking bolt (7) front end entered locking bolt alignment pin (6), inverse time screw key (1) drove locking bolt (7) and rotates, stem screws in locking bolt alignment pin (6) to groove (12), locking bolt (7) is stuck and can't withdraws from, and extracts key (1) out, reaches the locking purpose.
When European-allies undoes the lock, the rotation of insertion key (1) up time, the stem that drives locking bolt (7) screws out locking bolt alignment pin (6) to groove (12), and pull key (1) takes the member of tapered end (2) and locking bolt (7) composition out of, and unlatching finishes.
