The utility model has the advantages that the utility model adopts the split mode to perform a theftproof function; when the utility model is split, the utility model can not walk; furthermore, without the key of the owner of the utility model, other people can not assemble and use the utility model, and the safety antitheft performance is added to the utility model.

Description

Split type anti-theft bicycle

The utility model relates to a kind of bicycle, specifically is a kind of split type anti-theft bicycle.

Bicycle is that China is the most common, also is to use maximum vehicle.At present, miscellaneous bicycle is arranged on the market, for solving the stolen problem of bicycle, various anti-theft lock for bicycle, antitheft car body are also operated.But the stolen phenomenon of bicycle is still quite serious, and its reason mainly is that existing various antitheft lock pin, chain all are to be exposed to the outside, is prized down or cuts off by the people easily, and the thief is as long as pry open lock, and bicycle just can be walked, and arbitrarily uses.

The purpose of this utility model is at the deficiency in the prior art, provides a kind of with the theft-proof bicycle of split mode.

Structure of the present utility model comprises spider, front fork, wheel, pipe lock, brake cable etc., the Shang Gang of spider and Xia Gang are divided into front portion (1), (3) and rear portion (2), (4), forward and backward thick stick can be plugged into and disconnects by pipe lock (5), (6), following thick stick is a curvilinear figure, its welding lock pipe (6) locate into last thick stick parallel construction, brake cable (9) places perpendicular logical (7) top of front fork and perpendicular logical bottom, back.

The utility model has the advantages that: (1) is adopted and is carried out the mode of bicycle split antitheft, after the bicycle split, bicycle can't be walked, and under the situation of the key unlocking that does not have the car owner, other people use of bicycle can't being plugged into has increased the safe antitheft performance of bicycle greatly; (2) with lock and vehicle body molten be one, and, use bicycle with the lock state, the unlocking condition bicycle separates the mode of operation that can't use, make the thief with prize, cut, mode such as saw unblanks to steal, also can't use; (3) lock pin is included in the inside of pipe lock, makes the burglar be difficult to prize, cut, saw lock; This device can also be applicable to the bicycle of non-tripod structure.

Below in conjunction with drawings and Examples structure of the present utility model is further described.

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

Fig. 2 is the utility model pipe lock construction cutaway view.

By accompanying drawing as can be known, structure of the present utility model comprises thick stick front portion (1), last thick stick rear portion (2), following thick stick front portion (3), Xia Gang rear portion (4), last pipe lock (5), following thick stick pipe lock (6), front fork perpendicular logical (7), back perpendicular logical (8), steel wire brake cable (9), pipe lock (5), (6) be welded on the spider, Xia Gang rear portion (2), (4) front portion, before, back thick stick is by pipe lock (5), (6) plug into and disconnect, following thick stick front portion is a ＂ S ＂ shape, the rear portion is a ＂ C ＂ shape, interface section and last thick stick parallel construction, be convenient to plugging into and split of vehicle body, on, following thick stick front portion (1), (3) rear portion tubular stinger lock (5), (6) in, the lock pin groove (16) of respective tube lock has a punching lockpin hole (15), cylinder type tapered end (13) is contained in the place, the upper right corner of pipe lock, and pinning (12) laterally blocks lock pin (10).When pressing lock pin, lock pin passes lockpin hole (15), by key control pinning, blocks lock pin, is plugged into securely in the bicycle front and rear part, and the pipe lock is in locking states, and bicycle can be walked; When unblanking to shrink pinning, lock pin is under the effect of spring (11), and upward movement leaves lockpin hole (15) automatically, unclamp key, pinning resets, and still blocks lock pin, and bicycle front portion, trailing portion are disconnected, at this moment, the bicycle tube lock is in open state, and bicycle can not be walked.But manage the thick stick front portion and also be inserted in the through hole of pipe lock this moment, is convenient to bicycle parking when non-the use.Steel wire brake cable (9) is arranged at perpendicular logical (15) bottom in perpendicular logical (7) top of spider front fork and back, prevents scattering of front and rear part after the bicycle split, plays ＂ coupling fracture of wire and connects ＂.For preventing that lock pin from being prized, pipe is locked a lockpin sleeve (14) is set, and guarantees that lock pin can the separating lock cotter way.
