Description

The bicycle Band-type brake lock

Technical field

The utility model relates to a kind of bicycle lock.

Background technology

Existing various bicycle locks on the market, locking front-wheel or trailing wheel being arranged, the front fork of locking front-wheel is also arranged, is independent of each other between these bicycle locks and the bicycle itself, be that bicycle lock needs can realize the locking to bicycle by being installed in separately on the bicycle.Its disguise of the bicycle lock of An Zhuaning is not good separately, be easy to be found, and destroyed, and the anti-destructive of more existing bicycle locks itself is not good by the robber, in addition, the more existing good bicycle lock of theftproof performances exists complex structure, cost height, inconvenient deficiency is installed.

Summary of the invention

The purpose of this utility model is to provide a kind of and is combined with the bicycle shaft band-type brake and the bicycle Band-type brake lock that constitutes by lockout mechanism.

For achieving the above object, the utility model adopts following scheme: the bicycle Band-type brake lock, include brake disc and case, brake disc and case are contained on the axle aggregate, be provided with band brake apparatus in the case, in brake disc, be installed with a sleeve, the sleeve edge circumferentially be evenly equipped with double wedge, be installed with two～four bearing pins in the case, the backing plate that one middle part has through hole is contained on the bearing pin by the groove that has on it, be installed with a spring lock in the case, the lock core outer end of spring lock is connected with a pusher dog, and pusher dog departs from the axis of lock core, pusher dog is stretched in the waist shaped hole on the backing plate, be installed with socket on the backing plate, the jack on the socket is aimed at the sleeve upper raised teeth, and the two is a matching relationship.

By such scheme as seen, key is inserted in the lock core of spring lock and rotate, drive lock core, driving backing plate by the pusher dog on the lock core moves, when backing plate moved on the double wedge of jack sleeve at sleeve on it, the rotation of sleeve promptly was limited, thereby has limited the rotation of brake disc, make axle aggregate locking, promptly by this Band-type brake lock with on the bicycle lock.If the wheel shaft of locking will be unclamped, the backward rotation key drives backing plate by the pusher dog on the lock core and returns, and socket is separated with double wedge on the sleeve, and wheel shaft is promptly released, and promptly this band-type brake is opened.

The utility model constitutes the bicycle Band-type brake lock by in the band-type brake of existing bicycle shaft lockout mechanism being set, and it has compact conformation, cost is low, theftproof performance is good characteristics, and good concealment, is difficult for being found by the robber.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is further specified.

Referring to Fig. 1, be provided with by fork 1, tie rod 3 and brake facing 4 in the case 2 of this bicycle Band-type brake lock and constitute band brake apparatus, case 2 and described band brake apparatus are existing structure.Be installed with four bearing pins 7 in the case 2, the backing plate 5 that one middle part has through hole 21 is contained on the bearing pin 7 by the groove 6 that has on it, be installed with a spring lock 10 in the case 2, lock core 11 outer ends of spring lock 10 are connected with a pusher dog 9, and pusher dog 9 is stretched in the waist shaped hole 8 on the backing plate 5.

Referring to Fig. 2, an end of bearing pin 7 is fixed on the case 2, and the other end of bearing pin 7 passes backing plate 5.Spring lock 10 is fixed in the case 2, and the pusher dog 9 that is fixed in spring lock 10 lock cores 11 outer ends departs from the axis of lock core 11.Be installed with socket 14 on the backing plate 5, socket 14 is positioned at the inboard of backing plate 5.

Referring to Fig. 1, Fig. 2, in four bearing pins 7, on two bearing pins 7 pad 13 is housed away from spring lock 11, be connected on the groove 6 that an end hangs on the pad 13, the other end hangs over backing plate 5 of the spring 12 of 13 on backing plate 5 and pad.

Referring to Fig. 3, the socket 14 that is loaded on the backing plate 5 has jack 15.

Referring to Fig. 4, Fig. 5, be installed with a sleeve 17 in the brake disc 16, sleeve 17 edges circumferentially be evenly equipped with double wedge 18.Brake disc 16 is an existing structure, and sleeve 17 is fixed on the brake disc 16 by bonding or welding manner.

Referring to Fig. 6, brake disc 16 is contained on the axle aggregate 19 with case 2, constitutes a Band-type brake lock.Brake disc 16 also is an existing structure with the mounting means of case 2 on axle aggregate 19.The jack 15 of socket 14 is aimed at sleeve 17 upper raised teeths 18 on the backing plate 5, and the two is a matching relationship.By key rotation lock core 11, drive backing plate 5 by pusher dog 9 socket 14 on it is enclosed within on the double wedge 18, when promptly double wedge 18 was stretched in the jack 15, brake disc 16 was promptly locked.

As seen from Figure 6, this Band-type brake lock even unclamp nut 20, also can't make sleeve 17 separate vertically with socket 14 after on the bicycle lock.Thereby after having avoided the robber to unclamp nut 20, sleeve 17 is separated with socket 14,, improved the theftproof performance of this Band-type brake lock the possibility that bicycle is stolen.

In addition, by Fig. 1, Fig. 2 as seen, this Band-type brake lock is opened, after socket 14 separates with sleeve 17, when riding condition, be connected in the setting of the spring 12 of 7 of pad 13 and bearing pins, can avoid socket 14 being engaged with sleeve 17 because of reason such as jolting, and the phenomenon that causes bicycle to be lockable suddenly.
