Abstract

The utility model relates to an anti-prizing lock for a bicycle. A lock pin and a lock core are arranged in a lock body of the lock and lock holes and lock springs are arranged in the lock core. An outer fixed sleeve at the front of a bicycle frame and an inner sleeve for a front fork are drilled with circular holes and the cambered side surface of the square lock body with the lock pin is welded on a pipe surface at the rear part of outer fixed sleeve while the lock pin aligns the circular hole of the sleeve. A rack on the lock pin is mutually engaged with a gear on the lock core at a corresponding position. When the bicycle is locked, the front fork is rotated with 30 DEG so that the circular hole of the inner sleeve is aligned to the circular hole of the outer fixed sleeve, when a key is screwed, the lock core is rotated to move the lock pin to be inserted into the circular holes of the sleeves to play a locking action. The lock has the advantages of simple structure, convenient operation, bicycle and lock integration, and anti-prizing and anti-theft functions, and is suitable for various bicycles, tricycles and motorcycles.

Description

Bicycle Anti-Picklock

It is trivial to the utility model relates to a kind of bicycle pick-proof, and this kind pick-proof is trivial to be particularly suitable for the preceding overcoat seam of bicycle rack together.

Bicycle is being at present the vehicle that people's daily life be unable to do without, but every year a large amount of bicycle thefts is arranged all throughout the country, has become the hot issue of social concerns.And the various bicycles locking devices of people's application now, portion is the situation that car, lock separate.Need make lock lock pin pass a certain position that bicycle spoke is fixed on vehicle frame with bolt, nut or other modes.This kind fixedly lock method and used Vehicle lock structure burglar is easy to screwdriver or other tools used in crime lock be pried open and steals bicycle.

In order to solve the deficiencies in the prior art, the purpose of this utility model has proposed a kind of and the preceding overcoat seam Bicycle Anti-Picklock together of bicycle rack.

In order to realize the purpose of this utility model, its concrete technical solution scheme is: one side is leaned on tooth bar and is nibbled wheel for the relevant position in the square lock body of arc profile and is meshed.Be with circular hole in outer fixed cover and the front fork before the vehicle frame.The arc profile of lock body partly be fitted on the rear portion pipe face of outer fixed cover before the vehicle frame and seam together, make the circular hole of lock pin alignment sleeve, thereby make the pick-proof lock that locking fixes on the vehicle frame and vehicle frame becomes one.Lock is during car, turns the key that inserts in the lockhole and makes the motion of lock core rotating band pendulum lock pin that lock pin is inserted in the circular holes of two covers to make the front fork of car can not rotate the lock car effect of playing.

The utility model inserts in the hole of cover in fixed cover and the front fork lock pin just the relevant position on the rear of fixed cover outside the lock body seam is before vehicle frame, and front fork can not be rotated, and just can play the effect of lock car; So this kind Vehicle lock structure is simple, and is easy to operate, realize that car, lock are integrated, pick-proof and anti-theft.Be fit to use on various bicycles, three-wheel vehicle, boosted vehicle, the motor bike.

Make detailed description below in conjunction with drawings and Examples.

Fig. 1 is the utility model pick-proof lock locking state constructional drawing.

Fig. 2 is the utility model Figure 1A-A surface of a wound constructional drawing.

In the drawings, one side is drilled with two blind holes for the relevant position of the square lock body 4 of arc profile, and is vertical mutually and communicate on the two Kong Zaiyi cross section, and leading in the hole of arc surface has the lock pin 1 that can move back and forth, rotating lock core 5 is arranged in another hole, be provided with lockhole 6 and snap in the lock core 5.On the lock pin 1 tooth bar is arranged, lock core 5 corresponding sites have gear, and rack and pinion is meshing with each other.Before the vehicle frame in external fixation cover 3 and the front fork cover 2 (moving cover) be drilled with circular hole, but in the front fork circular hole center of cover 2 with respect to vehicle frame before the circular hole center of external fixation cover 3 on the cross section, differ 30 degree angles.The rear portion pipe face applying weld together of external fixation cover 3 before the arc surface of lock body 4 and the vehicle frame, and make lock pin 1 secured in alignment overlap 3 circular hole, lock body 4 and vehicle frame are fixed together, the burglar wants to steal car and has only the vehicle frame of damage just can steal.During the lock car, cover in the front fork 2 is rotated the circular hole that 30 degree make its circular hole secured in alignment cover 3, turn the key that inserts in the lockhole 6 and lock core 5 gears are rotated drive tooth bar lock pin 1 to move to insert in the circular hole front fork of car can not be rotated, front-wheel 30 degree that tilt again, the burglar can not auto theft.
