Description
Technical field
The utility model relates to a kind of new bicycle structuring anti-theft column lock, belongs to bicycle lock mechanical structure field.
Background technology
China is bicycle big country, and at present, maximum bicycle of using on market is exactly that prevailing bicycle, all can have a brake sticking brake system after it.
Existing bicycle lock is generally chain lock and ring lock.Chain lock is made up of tapered end and chain, and this lock inconvenience is positioned on bicycle, uses comparatively inconveniently, and its advantage is bicycle can be connected with fixing around object, prevents from that bicycle from being carried to steal.Ring lock can be connected on bicycle after unblanking, and has overcome the shortcoming of chain lock, but no matter be chain lock or ring lock, is all easy to its pinch off with locking pliers.The lock also having has applied to electronic product, has warning function, can carry out Remote to the switch of lock.But its cost is higher, only in the high-grade bicycle of minority, use.
At present the stolen main gimmick of bicycle is that lock is destroyed by force, but this does not affect the normal use of bicycle after stolen.So in the urgent need to a kind of new bicycle structuring lock, it is simple in structure, cost is low, and the structure of lock and bicycle itself is combined, and thief is difficult at the scene in the short time its destruction, even if destroy reluctantly, also make bicycle lose the value of service of itself.
Summary of the invention
When, lock stolen at bicycle is destroyed, bicycle still can normally use under normal circumstances.In order to reduce the stolen possibility of bicycle, simultaneously cost-saving, the utility model provides a kind of novel bicycle lock, and it can be by being connected with bicycle itself, makes the destroyed rear bicycle of lock normally use.
The technical solution adopted in the utility model is:
A kind of new bicycle structuring anti-theft column lock, comprise lock body, band-type brake shell and band-type brake friction wheel etc., lock body comprises lock housing, big spring and the little spring of lock core, snap close, lock core outside, lock core comprises inner core and outer core, inner core and snap close are all arranged on the inside of outer core, and one end of inner core puts in snap close, and the upper end of snap close contacts with lock housing through the groove on outer core, its lower end is supported by little spring, and little spring overlaps on the round platform of core inner lower end outside; Big spring is arranged in lock housing, and its one end contacts with lock housing and is connected, and the other end contacts with outer core and is connected; The madial wall of lock housing upper end is provided with a groove, and outer outer core lower end is provided with a boss; Described lock body is fixedly connected with band-type brake shell, and described band-type brake shell and band-type brake friction wheel are provided with the aperture inserting for outer core one end.
Further, between described lock body and band-type brake shell, be connected by rivet.
Described rivet adopts stainless steel rivet, and number is 2.
Further, between described lock body and band-type brake shell, be also provided with pad, gasket shape is crescent.
The utility model has the advantage of: simple and reasonable, with low cost, do not affect original band-type brake function, original structure, outward appearance are not made to larger change, take up room little, lockset is hidden, be not easy to be cut off, can greatly improve bicycle theft-prevention ability, there are wide market outlook.

Detailed description of the invention
The structure of the present embodiment as shown in the figure, provides a kind of structuring anti-theft lock for bicycle.Comprise the inner core 1 of lock, outer core 2, lock housing 3, pad 4, rivet 5, band-type brake friction wheel 6, connecting rod 7, big spring 10, snap close 11, little spring 12, groove 13, boss 14.Wherein: inner core 1, outer core 2, lock housing 3, big spring 10, snap close 11, little spring 12, groove 13, boss 14 has formed lock body as shown in Figure 4 jointly.Rubber 9 is fixed on brake iron sheet 8, and brake iron sheet 8 and rubber 9 have formed brake rubber block, and brake iron sheet 8 is connected with connecting rod 7.
As shown in Figure 2, lock housing 3 combines with pad 4, lock body is fixedly mounted on band-type brake shell by two rivet 5 entirety, in the middle of lock body and band-type brake, it is a pad 4, the shape of pad 4 is meniscate, can meet lock body like this and be arranged on the requirement of stationarity on band-type brake shell, the intensity connecting to strengthen rivet 5.
As shown in Figure 2, lock body center is to the distance in the macropore center of circle and definite according to the aperture center of circle on the friction wheel of band-type brake shown in Fig. 16 to the distance at band-type brake shell center, both equal and opposite in directions, plane and the folded angle of vertical plane surface of lock body center shaft and band-type brake shell center shaft composition are 35 degree.
As shown in Figure 4, inner core 1 and outer core 2 can only relatively rotate, can not relatively move, when locking, press lock core (being made up of inner core 1 and outer core 2), lock core just can move in lock housing 3, when groove 13 above moving to shown in Fig. 4, snap close 11 just can eject under the effect of little spring 12, is stuck in groove 13, and lock body profile when lock-out state as shown in Figure 2.Insert wherein in the hole that outer core 2 is aimed on band-type brake friction wheel 6, and outer core 2 hinders the relative motion of band-type brake friction wheel 6, realizes the function of car locking, and the relative position relation of lock body and band-type brake friction wheel 6 as shown in Figure 1.When release, be inserted in inner core 1 with key, rotate a certain angle, now inner core 1 will drive snap close 11 to move down, and snap close 11 opposed slots 13 also move down, under the effect of big spring 10, outer core 2 resiliences, exit the hole on band-type brake friction wheel 6, boss 14 is stuck in lock housing 3, completes release simultaneously.Outside drawing when release as shown in Figure 3.
As shown in Figure 1, have three apertures above band-type brake shell, a hole is the outer core 2 one end insertions in lock bodies, and two other connects used for rivet 5.Band-type brake friction wheel is connected with bicycle rear axle, keeps relative static with rear axle, moves along with cycle racing, along with bicycle is static and static.After bicycle stops, rotating trailing wheel to correct position, now just can press lock core, complete locking.
As shown in Figure 1, the distance that the outer core 2 of lock body stretches out band-type brake friction wheel 6 is shorter, because lock is closely connected by rivet with band-type brake shell, as destroyed lock, must destroy whole band-type brake structure simultaneously.In addition, the space of the inside is very little, joyriding does not have enough spanner spaces, make joyriding be difficult to steal bicycle by cutting off the outer core 2 of lock body, if destroy by force the lock body of outside, can cause very large noise on the one hand, cause others' attention, also can make on the other hand band-type brake entirety destroy, bicycle can not normally use.
