The specific embodiment

Below in conjunction with the specific embodiment the utility model is described further.

Referring to Fig. 1 and Fig. 2, buckle spoke disc type lock comprises lock shell 1 and is arranged on lock core 7, rotating shaft 4, locking plate 3, wind spring 5, the clamp 6 in the lock shell 1 and is used for the lockable mechanism with the locking position of clamp 6.Wind spring 5 is wrapped in the rotating shaft 4, and the inner of this wind spring 5 is fixed in the rotating shaft 4, and the outer end is connected with an end of clamp 6, can be captive joint, also can be to flexibly connect, and clamp 6 can move up with the contraction of wind spring 5.The other end of clamp 6 and lock core 7 are hinged, and can move down with the rotation of lock core 7, simultaneously tension coil springs 5.Locking plate 3 is fixedly installed in the rotating shaft 4, and an end of locking plate 3 stretches out lock shell 1, and the external part of locking plate 3 is provided with the locked groove 8 that can block the bicycle spoke dish; On lock shell 1 and the external part place of corresponding locking plate 3 be provided with the breach 2 that can supply locking plate 3 to rotate.Lock also be provided with on the shell 1 with the wheel installation shaft on the tapped bore 14 that cooperates of the outside thread that is provided with.

Lockable mechanism comprises lever 12, spring 11 and bayonet lock 9.The fulcrum of lever 12 is fixed on the lock shell 1, and this fulcrum is arranged on the midway location of lever 12; One end of lever 12 is a drive end, and bayonet lock 9 is fixed on the other end of lever 12, and clamp 6 is provided with the draw-in groove 10 that is used with bayonet lock 9, and draw-in groove 10 can only be provided with one, also can be provided with a plurality of.A plurality of draw-in grooves 10 are along being uniformly distributed with setting on the moving direction of this clamp 6, clamp 6 move above or below after, bayonet lock 9 all can insert in the draw-in groove 10 on the clamp 6, reaches the effect of double-deck braking.Spring 11 is arranged between bayonet lock 9 and the lock shell 1, and 11 pairs of bayonet locks 9 of spring apply the compressive pre-stress that snaps in draw-in groove 10.

For more convenient locking lock, on the drive end of lever 12, be provided with button 13, this button 13 stretches out outside the lock shell 1.

Lock core 7 and lever 12 are arranged on the both sides of tapped bore 14, have dwindled the volume of original lock, have reduced the waste in material and space.

Referring to Fig. 3, during installation, car lock case of lock 1 is installed on the wheel installation shaft, get final product through tapped bore 14 and wheel installation shaft screw thread fit are fixing.

The principle of work of the utility model is: lock is that the part as bicycle is installed on the wheel installation shaft, when needing locking bicycle, presses the button 13; Drive end at lever 12 applies a power, drives bayonet lock 9 motions, the draw-in groove 10 that bayonet lock 9 is broken away from the clamp 6 by lever 12; Wind spring 5 is packed up under the contractility of self automatically, drives rotating shaft 4 simultaneously and rotates, and locking plate 3 rotates to bicycle spoke dish direction thereupon; Locked groove 8 just is stuck on the bicycle spoke dish, and bicycle is locked.When unblanking, insert key and also clockwise rotate lock core 7, the turning cylinder of lock core 7 drives clamp 6 and moves down, and strains wind spring 5 simultaneously, and wind spring 5 drives rotating shafts 4 and rotates, and turns to erectility with the locking plate 3 of rotating shaft 4 one, and locked groove 8 leaves the spoke dish, realizes unblanking; Simultaneously, the bayonet lock 9 that has been applied compressive pre-stress by spring 11 snaps in the draw-in groove 10, stops clamp 6 upward movements.

This bicycle lock can be used as a clamp nut and is installed on the wheel installation shaft, as the part of bicycle, after unblanking, plays the effect of a nut, need not bring during use and take away, and is easy to use; If lock is forced damage, bicycle also is damaged simultaneously, makes the car thief can not easily complete steal car, has improved the anti-theft of lock greatly.
