Abstract

The utility model discloses a handlebar lock for a bicycle, wherein a front wheel and handlebars of the bicycle are connected through the handlebar lock. The handlebar lock comprises a hollow outer pipe, an inner pipe and a lock body, wherein the hollow outer pipe is divided into two sections which are respectively connected to the front wheel and the handlebars of the bicycle and are separated from each other; the inner pipe is positioned in a hollow cavity of one of the two sections of the outer pipe; when the lock body is opened, the inner pipe is pushed out from the hollow cavity of one of the two sections of the outer pipe, and connects the two sections of the outer pipe; when the lock is closed, the inner pipe retracts into the hollow cavity of the outer pipe, and the two sections of the outer pipe are separated. When the handlebar lock is locked, the bicycle can not be used; if the handlebar lock is destroyed, the inner pipe can not normally realize the positioning function, the handlebars and the front wheel of the bicycle are still separated, and the bicycle still can not be normally used. Thus, the prior theft method with lockset destroying as a main means fails to be effective to the handlebar lock, thereby improving the safety of the bicycle.

Description

Bicycle handle bar's lock

Technical field

The utility model relates to bicycle lock.

Background technology

The theft problem of bicycle is a very insoluble problem always.Solution commonly used at present is the quantity that increases common lockset, perhaps uses complicated, firm more lockset, to increase thief's the difficulty of committing theft.But, no matter how the quantity of lockset increases, how the intensity of lock improves, its basic principle all is the same, as long as destroyed lockset itself, just can all successfully take bicycle away, and the damage of lockset can influence the normal use of bicycle hardly, thereby along with the appearance of the strong instrument of destructive power, the difficulty of taking precautions against the bicycle theft is more and more higher.

So, just need a kind of new technology that avoids theft.

The utility model content

The utility model proposes brand-new theft-prevention structure, the handlebar of bicycle is separated with front-wheel, when the lockset locking, handlebar separates with front-wheel, and this moment, bicycle can't use, and therefore can increase the difficulty of committing theft of stealer greatly.

Implementation of the present utility model is as follows:

A kind of bicycle handle bar lock, wherein the front-wheel of this bicycle is connected by the handlebar lock with handlebar, and the handlebar lock comprises: the outer tube of hollow, the outer tube of this hollow are divided into two sections, connect the front-wheel and the handlebar of bicycle respectively, and these two sections outer tubes are disconnected from each other; In pipe, be positioned at one of them cavity of two sections outer tubes; When lock body, lock body are opened, interior pipe is released in the cavity of one section outer tube wherein, and by should in pipe two sections outer tubes are linked to each other, during the lock body locking, interior pipe is withdrawn in the cavity of outer tube, two sections outer tubes separate.

Usually, interior pipe is positioned at the cavity of the outer tube that connects the bicycle front-wheel.Should also have fastening devices by interior pipe, with two sections outer tubes connections and fixing.

Adopt the technical solution of the utility model, bicycle can't use when the lockset locking, if destroyed the handlebar lock, interior pipe can't normally be realized the effect of locating, and the handlebar of bicycle still separates with front-wheel, and bicycle still can't normally use in fact.What Here it is can't work to handlebar lock of the present utility model based on the method for committing theft of destroying lockset traditionally, thus the safety that improves bicycle.

Description of drawings

Fig. 1 is the structural representation of handlebar lock of the present utility model.

The specific embodiment

Because means commonly used were to destroy lockset during present bicycle was stolen, and the instrument destructive power of destroying is more and more stronger, so merely dependence increases the quantity of lock or improves the phenomenon that the intensity of locking also can't be contained theft effectively.The utility model provides a kind of brand-new means, and when lockset was destroyed, bicycle can't use, and only under the situation that guarantees that lockset is intact and normally opened, can normally use bicycle, thereby reaches the purpose of protection bicycle.

With reference to shown in Figure 1, the invention provides a kind of bicycle handle bar lock, not directly to connect between the front-wheel of the bicycle of use bicycle handle bar lock and the handlebar, but connect that this handlebar lock comprises by the handlebar lock by traditional steel pipe:

The outer tube of hollow, the outer tube of this hollow are divided into two sections, connect the front-wheel (outer tube 11a) and the handlebar (outer tube 11b) of bicycle respectively, and these two sections outer tubes are disconnected from each other, and promptly the front-wheel of bicycle only relies on outer tube not to be connected with handlebar.

In pipe 12, be positioned at one of them cavity of two sections outer tubes, usually, interior pipe 12 is the cavities that are positioned at the outer tube 11a that connects the bicycle front-wheel.

Lock body 13 when lock body 13 is opened, is released interior pipe 12 in the cavity of one section outer tube (such as outer tube 11a) wherein, and by should in pipe 12 two sections outer tubes are linked to each other.Can also have fastening devices 14 on the interior pipe 12, with two sections outer tubes connections and fixing.Open when lock body 13, pipe 12 and two sections outer tubes are coupled together and fixedly the time, handlebar just is connected with front-wheel in releasing by interior pipe 12, this moment, handlebar can be controlled front-wheel, and bicycle can normally use.During lock body 13 lockings, interior pipe 12 is withdrawn in the cavity of outer tube, and two sections outer tubes separate, and handlebar also separates with front-wheel, and in fact bicycle can't use.

Usually, interior pipe 12 is to be placed in the outer tube of the front-wheel that connects bicycle, relies on the effect of gravity, if there is not the effect of external force, interior pipe 12 can not stretch out from outer tube, so the effect of lock body 13 is to apply external force interior pipe 12 is released from outer tube.So, if lock body 13 is destroyed, under normal situation, can't apply external force to interior pipe 12, so interior pipe 12 can't stretch out, also just can't connect two sections outer tubes from outer tube, so handlebar and front-wheel still separate, bicycle still can't use.

In addition, two sections outer tubes of pipe connection became very difficult in the feasible object with other of the fastening devices on the interior pipe replaced, and fixedly outer tube also can't normally use bicycle.

Because the bicycle that destroys behind the lockset can't use, the thief can not continue to commit theft the therefore safety that can effectively improve bicycle usually again owing to carry inconvenience.

From top explanation as can be known, adopt the technical solution of the utility model, bicycle can't use when the lockset locking, if destroyed the handlebar lock, interior pipe can't normally be realized the effect of locating, and the handlebar of bicycle still separates with front-wheel, and bicycle still can't normally use in fact.What Here it is can't work to handlebar lock of the present utility model based on the method for committing theft of destroying lockset traditionally, thus the safety that improves bicycle.
