CN2369931Y - Foot support convenient lock for bicycle - Google Patents

Abstract

The utility model relates to a foot support convenient lock for a bicycle, which is composed of a foot support, a transmission cover, an eccentric wheel, a stop slide block, a stop gear, a lock core, etc., wherein, the foot support is provided with a pusher dog which can drive the eccentric wheel. When the eccentric wheel moves, the stop slide block is shrunk for clamping the stop gear which is arranged on a flower-drum cylinder of a rear bicycle axle, the lock core controls a spring clamp for limiting the eccentric wheel to rotate, and thereby, the bicycle can be locked or opened. The lock for the bicycle can be designed and arranged by being connected with a rear bicycle brake into integration. The utility model has the advantages of simple structure, low cost, convenience, time saving, safety, and anti-theft effect.

Description

The convenient lock of bicycle support leg

The utility model relates to a kind of lock, is mainly used in bicycle, and vehicles such as motor bicycle prevent the vehicle loss.

The present various bicycle locks that use, though various in style, cut both ways, what have is simple to operate, but the anti-theft pick-proof poor performance, the theftproof performance that has is good, but complex operation, or very heavy, and the key of great majority lock is not will be inserted in to lock exactly and will draw repeatedly.The key that is inserted on the lock has been forgotten to take off easily, and then locking and unlocking in addition all will be drawn key, and is again and again extremely inconvenient, causes to have forgotten the lock car sometimes or key is lost easily.

The purpose of this utility model be overcome existing bicycle lock most of shortcoming and at the bottom of a kind of integrated cost of design-calculated, operate extremely easy, time saving and energy saving, prevent to forget, easy convenient lock of bicycle support leg of keeping of safe antitheft, key.

The utility model is achieved in that by heel brace, lock, shell, deflecting wheel, stop slider, stopping gear, elasticity card, lock core, the car convenient lock of bicycle support leg of component set-up such as stop.Be characterised in that heel brace is converted into V-type, following point is gone up circle, is furnished with transmission shield, and rebound spring is housed, and the transmission shield center is porose to be contained in the left side of bicycle rear axle together with the lock shell, and the rotating mask outer diameter side is along two pusher dogs are arranged.Put in the lock shell by crescent and to be connected with deflecting wheel, there is a projection in the deflecting wheel outside, and three equidistant stop slider are arranged in the internal diameter, is fixed on the lock shell by the slide block outer cover, spring is arranged in the slide block, make slide block be radial motion to the outer by the center of circle of lock shell.Stopping gear is contained in the left front end of bicycle rear Decorative drum, put in the lock shell approaching with stop slider, during parking, stir deflecting wheel when heel brace falls, after about 45 ° of the deflecting wheel deflection, outside projection is blocked by Spring Card, inwall is oppressed stop slider simultaneously, and slide block is shunk to the axle center.Slide block two side bottoms insert stopping gear, promptly finish the locking task of bicycle rear automatically.Use key rotation lock core during driving, push Spring Card aside, deflecting wheel recoils to original position automatically together with heel brace, and heel brace also recovers to lift state.

Advantage of the present utility model is that the car owner needn't remove to lock car with hand, also need not painstakingly remove to lock car, utilizes the task of must finish the lock car when stopping with the foot-operated action of heel brace down simultaneously.Simplified the program of lock car, convenient and time-saving, can prevent also that the somebody from having forgotten the lock car in the moment of desperation, cause loss, this lock when stopping without key.Key also need not be inserted on the lock, only uses key when unblanking.End lock back key and take off, can put together to be convenient to take care of with other key safely be difficult for losing.The position that lock is installed is more hidden, but pick-proof and anti-theft, be locked in when closing, the front of slide block is blocked the inboard and the rear drum tube of stopping gear and is killed, even trailing wheel is unloaded, lock also is difficult to open, fool proof, this lock is designed to one with heel brace, lock and present popular back axle braking device, can fall end production and material cost.

Further describe the utility model below by drawings and Examples.

Accompanying drawing 1 is the utility model inner structure scheme drawing, and accompanying drawing 2 is cut-open view of final assembly.

1. female 18. packing rings, 19. heel braces of stopping gear 2. deflecting wheels 3. slide block outer covers 4. slide block inner springs 5. stop slider 6. lock shells 7. rotating mask pusher dogs 8. Spring Cards 9. springs 10. set pins 11. switch pusher dogs 12. lock cores 13. transmission shields 14. spring set pins 15. rebound springs 16. axle bushes 17. hexagonal Luo 20. lock bodies 21. Decorative drums 22. back axle brake gears.

Simultaneously can stir latching device again for making heel brace can finish self support task, heel brace is designed to V-type, following point is gone up circle, and the round part in top is welded with transmission shield, and the transmission shield center is porose, and is furnished with rebound spring, be enclosed within on the back axle axle bush, can freely rotate, there is pusher dog at the transmission shield two ends, connect the deflecting wheel in the lock housing, there is a projection at the deflecting wheel edge.Transmission shield was together with 45 ° of rotations of deflection crop rotation when heel brace fell, and projection is promptly blocked by Spring Card, and heel brace keeps the state that lands, and car body is propped.The internal diameter of deflecting wheel has three irregular inclined-planes, form drop, thus deflecting wheel when rotating three stop slider (being furnished with spring) that are fixed on the lock housing shrink to the axle core simultaneously, it is stuck to shrink the stopping gear that will be contained in when putting in place on the car Decorative drum of back, rear wheel promptly is lockable, and can't rotate; Reach the purpose of lock car.When the car owner uses car, key is inserted lock core, rotate a little in the direction of the clock, lock core drive pusher dog is about to Spring Card and pushes aside, and deflecting wheel under the effect of rebound spring, goes back to original position together with transmission shield.Stop slider to the outer expansion, breaks away from stopping gear simultaneously, and heel brace also lifts synchronously, and trailing wheel recovers rolling condition.

Whole device simplicity of design, but most of accessory punch forming, supporting the most reasonable with the rear axle brake, the shell that only will brake is changed a little and is got final product, and does not influence the function of existing brake part at all.
