Description

The locking device for bicycle improvement

Technical field

The utility model relates to the improvement of a kind of locking device for bicycle, make it to have except can be sealed self antitheft effect, (for example: railing) must take precautions against bicycle and be removed the effect of stealing by integral body also can be locked together in outer object.

Background technology

The cable-styled locking device for bicycle of traditional type, its structure all are to be shown in accompanying drawing 1 and accompanying drawing 2, are one to have the body 1 of lock core 2, locking holes 3, and body 1 is provided with the lock rope 4 (steel lock or chain) of one, and the termination of lock rope 4 is provided with the tenon 5 of one.When it uses, will lock rope 4, tenon 5 passes vehicle frame 7 and wheel rim 8 thereof, again with tenon 5 insertion bodies 1, and by latch receivers (lock) the matching joint head 5 of lock core 2, when opening, then open lock core 2 and make tenon 5 be broken away from locking holes 3 on the body 1 by key 6; Though above-mentioned lock can reach the purpose that bicycle is locked, but, have following shortcoming: it can only be locked by bicycle self, can not with the sealed binding one of other foreign object (for example: railing, post, weldering formula iron gate, another bicycle), so " even self locks " still has by " whole bicycle " and mentions, carries the possibility of stealing, bicycle especially now, whole light weight, general teenager can mention easily.Therefore, the locking device for bicycle of traditional type has antitheft not good shortcoming really, is " can only prevent gentleman, can not prevent the person of low position ".The lock body of traditional type because of being " can not be directly sealed with vehicle frame ", so storing when not in use must be installed " holder " folder in addition additional and decide it, perhaps adopt the canoe fit, but its lock body is fixing in addition, can collide vehicle frame because of vibrations.

Summary of the invention

It is a kind of except bicycle is carried out " self locks " that the purpose of this utility model is to provide, also can with other foreign object (for example: sealed binding one railing), make bicycle can't whole quilt remove the locking device for bicycle improvement of stealing.

The technical solution of the utility model is: a kind of locking device for bicycle improvement, comprise the body that has lock core and locking holes, lock rope, key, the tenon that is connected with body, described locking holes and tenon have two kinds of duties, first duty is that tenon inserts and to make in the locking holes that tenon and body are sealed to be one, and the 2nd T is that tenon and locking holes are separated unblanking afterwards as state; Described tenon is separated with body or lock rope under second duty, and tenon is fixed on the vehicle frame.

The specific embodiment

See also accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, a kind of locking device for bicycle improvement, comprise the body [20] that has lock core [21] and locking holes [22], the lock rope [23] that is connected with body [20], key [24], tenon [12], described locking holes [22] has two kinds of duties with tenon [12], first duty is that tenon [12] inserts and to make in the locking holes [22] that tenon [12] and body [20] are sealed to be one, and second duty is to be separated with locking holes [22] at the back tenon [12] of unblanking; Described tenon [12] is separated with body [20] or lock rope [23] under second duty, and tenon [12] is fixed on the vehicle frame [7].Described lock rope [23] is provided with lasso [230], and passes for other sections of body [20] and lock rope [23] thereof, can wear and close, restraint and close vehicle frame [10] outer object [9] in addition shown in accompanying drawing 4 and accompanying drawing 5.Its structure of following structure describes its advantage:

One, anti-theft effect is good, easy to use:

As shown in Figure 4, it is the unexistent effect of traditional type, during use, to lock rope [23] frame (cover) and outer object [9], lock rope [23] with body [20] and leading portion thereof passes lasso [230] again, at last the locking holes [22] of body [20] is plugged together on the tenon [12] to the vehicle frame [10], and forming tenon [12] sealed with body [20] is one, bicycle integral body, body [20], lock rope [23], outer object [9] are linked be one, use extremely simple, convenient.

By above-mentioned explanation as can be known, it is one that the utility model can make bicycle integral body link with outer object [9], therefore, whole of bicycle can't be mentioned and move away from, and takes precautions against the problem of being stolen by whole carrying, and the strick precaution effect is splendid." can supply to wear the object of combination " because should outer object [9] can be again for the railing of jam, post, street lamp bolt, welding rod shape iron gate, another own controllable bicycle or other, fixed object arround fully cooperating reaches the strick precaution bicycle and is removed the problem of stealing by whole.

In addition, when not in use, tenon [12] just can be as holder.Body [20] can be solidly plugged on the tenon [12], lock rope [23] is not locking state, reaches fixed effect splendid when putting.

But two self lock:

As shown in Figure 5, the utility model also can be the state of " self locks " certainly, be that lasso [230], lock rope [23] are passed wheel rim and vehicle frame [10], again body [20] is passed lasso [230], locking holes [22] on the body [20] can be inserted and be locked on the tenon [12], form the state of " self locks ", use effect good.

Three, also can implement to be the kenel shown in accompanying drawing 6 and the accompanying drawing 7 according to above-mentioned technological means, the utility model, be lock rope [25] to be bent be set as lasso [250], can obtain accompanying drawing 3 identical effect, purpose, belongs in the equivalent structure intention category of the present utility model.In addition, this tenon [12] also can be located at the vehicle frame place in the place ahead (front-wheel) or be located at the main vertical welding bar [101] of cushion or the horizontal position welding bar [102] of vehicle frame is located, and all belongs to equivalent structure of the present utility model.
