Description

Built-in bicycle axis closing appliance

The utility model relates to a kind of anti-theft security lock designing technique of bicycle, particularly a kind of bicycle in-to-in axis closing appliance that is built in.

At present, the outer substantially portion of the anti-theft locking of bicycle independently lock locks and finishes, in any case but many locks improve or reinforce, still can lock be destroyed from the outside, then complete vehicle is stolen out, processing just can be peddled or be used a little.Sell though there is at present the tamper-resistant safety of various structures to lock out, it is still serious that bicycle is prized stolen situation.At present existing " bicycle headstock lock " (China Patent No. 89208159.7), the anti-theft bicycle of " beam-inserted lock " lock one such as (China Patent No. 92116346.4), but yet there are no the technology of putting down in writing the bicycle middle shaft closing appliance.

The purpose of this utility model provides a kind of built-in bicycle axis closing appliance, it can accomplish car is locked in car, realize frame lock integrated anti-theft effect, be both made behind the lock stolen, the thief is under no key situation, if destroy lock by force, then make car body suffer partial disablity, surface fracture and be not suitable for using, and then can give up the thief and carry out the thought (motivation) that picking lock is stolen.

The utility model is realized with following technical scheme: it still comprises lock frame (lock body), be located at ball lock head lock core (for the common spring lock core) and locking bar in the lock frame lock body, it is characterized in that described lock frame lock core is to be installed in the seat tube with built-in, but also be provided with movable clamp and driving gear shaft rod that left and right sidesing shifting slides in lock frame inside, described locking bar is to make telescopic bayonet lock (bar) formula structure, in addition design is processed with tooth (wheel) groove that can close with bail type locking bar bottom active card scarf on the axis rod in the cycle frame center tap, offer the bayonet socket that can be movably fastened with clamp in the upper end of locking bar (left surface), the another side of locking bar bayonet socket offer can with gear shaft rod mating teeth bar, when the handsetting gear axostylus axostyle can drive that locking bar moves down and with the teeth groove clamping (inlay card) of axis rod, allow clamp (to the right) move simultaneously and engage with the bayonet socket of locking bar top, can realize locking, make it throw off the locking bar bayonet socket when promoting clamp (left) displacement by shifting block, and the locking bar teeth groove of throwing off the axis rod that moves up can be realized unblanking with key rotation lock core.

The principle of work of the utility model closing appliance is from the above: with the axis rod of spline as locking member, the interior formation of center tap that the axis rod is installed in bicycle tripod passes (commentaries on classics) moving element, it can be ended movably, only promptly pinned bicycle, moving then open locking, wheel can be driven move ahead.During last latching operation, the knob of only with hand arm revolving gear axostylus axostyle, locking bar is promoted (to bottom offset) downwards and block bottom bracket axle tooth () in the groove, clamp (under the tension spring effect) moves to right automatically and blocks the bayonet socket of locking bar top then, promptly reaches the locking purpose.When unblanking, must use key rotation lock core, the shifting block promotion clamp disengaging bayonet socket by the lock core end allows locking bar get upward displacement under the tension spring pulling, throws off the bottom bracket axle teeth groove, the axis rod can be rotated promptly realize unblanking purpose.

Compared with the prior art, the utility model is loaded on (or being positioned at the connection pipe that connects) in the seat tube by locking frame lock core and other locking parts, and is stolen very effective to the prevention bicycle, because

In a single day if stolen bicycle does not have key just can not open use, and destroyed Vehicle lock structure by force, car can't be used by breakage also can, allows the thief lose the meaning of stealing car.The utility model can make things convenient for locking and unlatching, also can be used for using on the similar three-wheel vehicle of structure and other non-power-driven vehicle.

Following accompanying drawing is a kind of embodiment explanation of the present utility model:

Fig. 1 is an integral structure scheme drawing of the present utility model (longitudinal diagram)

Fig. 2 is the generalized section of Figure 1A-A direction

Fig. 3 is the generalized section of Fig. 2 B-B direction

Wherein: 1～axis rod, the teeth groove of 2～axis rod, 3～seat tube, 4～bail type locking bar, 5～upper supporting part (seat), 6～lock frame (lock body), the tension spring of 7～clamp (back-moving spring), 8～movable clamp (can engage) with the bayonet socket of locking bar top, the protective-cover type connection pipe of 9～standpipe and lock frame, 10～case, the tension spring of 11～locking bar, 12～bolt (tension spring is installed to be used), 13～saddle tube (being the upper section of standpipe), 14～gear shaft rod, 15～lock core, 16～lower supporting part, the bayonet socket of 17～locking bar top, the tooth bar of 18～locking bar top, the center tap of 19～triangular frame, 20～gear wheel shaft knob, 21～lock core pulls out head, the guiding square groove hole of 22～clamp, 23～lock frame incision sheet, 24～lock frame protecgulum.
