Abstract
The present invention relates to a theftproof bicycle which comprises handles, a front fork, a front wheel, pedals, a rear wheel, a seat, a bicycle frame, a key, a lock and a lock plunger. The cross section of a vertical fork (7) of the bicycle frame (10) is cut off completely or partly; a through hole sleeve barrel (8) and a blind hole sleeve barrel (11) are respectively welded in the cut-off position of the cross section so that the bicycle frame, the through hole sleeve barrel and the blind hole sleeve barrel form an indivisible lock body. Thus, an individual member composed of the lock and the lock plunger which are operated by the key can be inserted into the through hole sleeve barrel and the blind hole sleeve barrel to lock a wheel. Because the key positions of the lock and the lock plunger are closed by the two sleeve barrels, if a thief damages the sleeve barrels, the bicycle frame is also damaged. Thus, the theftproof bicycle can not be ridden or sold by the thief.

Further improve as the present invention, can adapt to high-grade bicycle adopts, with non-metallic materials such as fibers whole make or with metallic materials such as aluminum alloys whole make vehicle frame in, common integral body on the position of upright fork or horizontal fork creates with through hole sleeve and blind hole sleeve.
Described tapered end is formed the closedown structure that can insert two sleeves of anti-theft bicycle by connecting pin and locking bolt, can extract back two sleeves of disengaging when riding again deposits separately, the locking bolt front end is provided with tongue that horizontal longitudinal phase hands over or tongue always, tapered end is provided with tongue always or is provided with the pin that rises and falls of a knee-action, and the knock hole of rise and fall pin and through hole sleeve is corresponding.
Anti-theft bicycle of the present invention is compared with the bicycle of prior art has following advantage: factory has finished the manufacturing of lock body again when making vehicle frame, make vehicle frame both keep original purposes and rigidity, has anti-theft feature again, the assembling of spraying paint of two sleeves and vehicle frame integral body is dispatched from the factory, both elegant in appearance, sturdy and durable again, eliminated the worry of wanting purchase of customer, installation lock in the past, reduced the weight and the cost of lock.And adopt independently locking bolt member, the anti-saw of this member shearing resistance is anti-pounds long service life, for example when this member contingency has quality or other problems, can change at any time, not influence the use of bicycle, not resemble halter lock etc., scrap once key is lost or lock self to damage, residual body has then become the burden of car.Above-mentioned technical characterictic can also be applied on electric power, the motion-aiding bicycle of fuel and various motor bike.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the front view of ordinary bicycle of the present invention.
Fig. 2 is the front view of high-grade bicycle of the present invention.
Fig. 3 is the cutaway view of the upright fork of vehicle frame of the present invention and lock body, locking bolt.
Fig. 1, Fig. 2 and anti-theft bicycle shown in Figure 3 are by handle (1), front fork (2), front-wheel (3), step (4), trailing wheel (6), through hole sleeve (8), seat (9), vehicle frame (10), blind hole sleeve (11), locking bolt (12), locating dowel pin (13), connecting pin (14), tapered end (15), key formations such as (16).
Fig. 1 is the embodiment on ordinary bicycle: the cross-sectional plane that the upright fork (7) of vehicle frame (10) is in position in the trailing wheel blocks fully or part is blocked, press the sharp processing one circular arc interface of through hole sleeve (8) and blind hole sleeve (11) in the truncated position, then through hole sleeve (8) and blind hole sleeve (11) are placed on respectively in the circular arc interface of truncated position, the axial line of two sleeves is overlapped, use the welding method firm welding again, perhaps install firmly with additive method, in addition, also can not block upright fork (7), directly with two sleeves (8), (11) be welded on its side, two sleeves are connected to become an indivisible lock body by vehicle frame (10), and both vehicle frame (10) became the part of lock body.
