Description

A kind of novel rim lock

Technical field

The utility model relates to a kind of bicycle rim lock.

Background technology

The bicycle lock that uses is gone up by society at present, mostly be fixed on the bicycle front fork or the back vent of cycle frame on, lock ring passes wheel rim wheel rim is pinned, this lock, had an accident owing to lock ring vibrates easy self-locking, and it is motionless simply to pin the fixed bit wheel.What the market popularity was many pins wheel rim with steel wire or chain, this class lock periphery all is with on the plastic sheath, during use the wheel rim pinning is not rotated, and volume is big, inner steel wire or chain are generally disconnected once cutting with scissors, and time one is long, plastic deformation and splitting, and folding and unfolding is very inconvenient, as want design than strong anti-theft feature, the materials manufacturing cost is bigger, all hangs onboard when not using, and is very unbecoming.Also has a kind of U-shaped lock, the lock ring of this lock is made with round steel, and the pipe rheo-die-casting that lock bridge has is because structure is not compact, volume increases, use inconvenience, want to improve theftproof performance, all must increase the steel weight and volume and improve anti-theft feature, therefore when selecting the good lock of anti-theft feature, must increase the subsidiary weight of bicycle in the way of travelling and hang over additional body that should not have of bicycle, bring a kind of puzzlement when selecting, so do not reach desirable effect to people.

Summary of the invention

The utility model has overcome above-mentioned shortcoming, designed a kind of novel rim lock, this lock is achieved in that by key, lock body, tapered end, the U-shaped plate, main lock ring, secondary lock ring, rivet is formed, be provided with tapered end in the lock body, inside is provided with lock core, pellet shot from a slingshot, spring, the tapered end front end is provided with stop, stop is by key, spring drives, the bottom of U-shaped plate is circular arc and fixedlys connected with main lock ring, secondary lock ring flexibly connects by connecting axle and main lock ring, have on the secondary lock ring keeper and with lock body in stop be complementary, the centre of U-shaped plate is provided with lock body, and is by rivet lock body to be fixedlyed connected with the U-shaped plate.The utility model structure is very simple, and theftproof performance is very good, and can be according to size adjustment master's lock ring of bicycle, electric motor car, motorcycle wheel rim, secondary lock ring size shape.This lock is compact conformation not only, and the materials cost is low, and easy to manufacture, applicability is wide, uses very conveniently, and the back of unblanking is carried very conveniently because of volume for a short time, is applicable on bicycle, power assist vehicle, the motorcycle and uses.

The specific embodiment

A kind of novel rim lock of the present utility model is by key 2, lock body 5, tapered end 3, U-shaped plate 9, main lock ring 1, secondary lock ring 8, connecting axle 10, rivet 4 is formed, lock body 5 is provided with stop 6, spring 10, be provided with lock core in the tapered end 3, pellet shot from a slingshot, spring, U-shaped plate 9 is fixedlyed connected with main lock ring 1, U-shaped plate 9 centres are provided with lock body 5 and fixedly are connected as a single entity by rivet 4, main lock ring 1 flexibly connects by connecting axle 10 with secondary lock ring 8, secondary lock ring 8 one ends establish keeper 7 and with lock body 5 in stop 6 corresponding couplings, pull key 2 when unblanking, the lock core rotation drives the keeper 7 that stop 6 leaves secondary lock ring 8, and lock is promptly opened; During locking, secondary lock ring 8 compresses to lock body 5 directions, and the inclined-plane of keeper 7 front ends is stressed to stop 6 contacts on secondary lock ring 8, and return pins because stop 6 springs 5 are stressed.The utility model is very simple, and uses very convenient.

During the utility model locking, main lock ring, secondary lock ring and U-shaped plate form circle, and lock body is square or rectangle.
