Abstract

The utility model provides an anti-theft device for bicycle and motorcycle, wherein an U-shaped lock fork is sheathed with a fixing ring connected with a ground embedded part; a movable shaft is in inserting connection with the lock fork by a through hole arranged on an open end of the lock fork, which locks the lock fork; one end of the movable shaft is locked by a spring lock arranged inside a sleeve; the lock fork and the movable shaft are both manufactured by hollow pipes; because a bicycle or a motorcycle in a shed is locked by a concealed lock and the anti-theft device is firmly connected with the ground or the fixed structure, the bicycle or the motorcycle is hard to move, thereby the utility model is suitable for non-motorized vehicles to be used in yards and sheds for the sake of anti-theft.

Description

Bicycle, anti-theft device for motorcycle

Affiliated technical field: the utility model relates to the vehicle anti-theft technical field, particularly a kind of bicycle, anti-theft device for motorcycle.

Background technology: present stage bicycle, motor bike and the stolen situation of other unpowered vehicle often take place, though bringing in constant renewal in, anti-theft measure regenerates, antitheft burglar lock is various in style, style is different, vehicle parking also locks with two kinds of locksets in garden, penthouse for motor car, but still keep away unavoidable stolen generation, stealer uses and destroys the disconnected lockset of clamp, and what have even need not tackle lockset but simply car load is lifted the theft vehicle of race simultaneously together with lockset.

The utility model content: the utility model provides a kind of bicycle, anti-theft device for motorcycle, the vehicle that it adopts the hidden lockset will be placed in the bicycle shed locks, and anti-joyride device firmly links to each other with ground or fixed buildings, thereby vehicle is difficult to be moved, and has improved theftproof performance.

The utility model reaches by following technical measures: U-shape lock stick be with ground on built-in fitting bonded assembly set collar, movable axis and lock on the forked end prefabricated through hole intert to link to each other and will lock the fork closure, movable axis one end is locked by the spring lock that is arranged in the sleeve.

Described U-shape lock fork and movable axis all adopt the hollow tubular of Φ 2.5cm to make; The 3mm plate iron of perforate in the middle of the welding one in the sleeve, an end of movable axis passes this perforate and spring lock links; Be shaped on key with cooresponding position, cylinder of spring lock hole on cartridges sides or the bottom surface and insert window.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

As shown in the figure, the utility model is made of set collar 1, U-shape lock fork 2, movable axis 3, the sleeve 4 of hidden spring lock 5 and the horizontal steel plate 6 that welds in sleeve.

Using method: will lock fork one end and penetrate on the set collar that links to each other with ground or building, the other end pierces in bicycle or the motorcycle front-wheel, plugs movable axis and will lock the fork sealing; Overlap upper bush again, movable axis passes the steel plate middle opening in the sleeve, and its tail end hangs up spring lock locking.During unlatching, two refer to hold the spring lock lock body, key is injected from sleeve window get final product unlocking spring lock, withdraw from spring lock subsequently and can extract movable axis, take from driving or motor bike.

Advantage of the present utility model or good effect:

The anti-theft device that the utility model provides is safe and reliable, and spring lock adopts hidden to be positioned at sleeve, in addition The U-shape lock fork of outer openings at one side have thicker caliber, thereby it is disconnected to be difficult for destroyed clamp for hollow pipe, Can prevent that lock body from being prized or clamp; It and ground are fixedly linked in addition, are difficult to be moved. This anti-theft device is suitable Should use at garden, carport, can be for the antitheft use of various bicycles.
