Abstract

The invention discloses a bicycle lock. A lock body is connected with a saddle, and the strut of the saddle of a bicycle is provided with a strut torsion device. When the bicycle is locked, the strut of the saddle is bent by the strut torsion device of the saddle, and the lock body passes though a wheel to form a locking device. The bicycle lock and a bicycle body are integrally designed, so that the bicycle lock is convenient to use and high in reliability.

Description

A kind of bicycle lock

Technical field

The present invention relates to a kind of bicycle lock, particularly with the bicycle lock of bike saddle one.

Background technology

In the prior art; The design that bicycle lock is taked to leave with the bicycle status usually or comparatively complicated and the design of vehicle body one voluntarily; Use and carry inconvenience with the lock design that the bicycle status leaves; Comparatively complicated and the lock design of vehicle body one voluntarily exist safeguard inconvenient, fault easily, problem such as reliability is relatively poor.

Summary of the invention

Use deficiencies such as inconvenient, that reliability is relatively poor in order to overcome the prior art bicycle lock, the present invention provides a kind of and the bicycle lock bicycle saddle integrated design.

The technical solution adopted for the present invention to solve the technical problems is: the bicycle lock body links to each other with vehicle seat, and the pole torsion device is set on vehicle seat pole, makes the bending of vehicle seat pole through vehicle seat pole torsion device during the lock car, lock body is passed wheel constitute Locking Device.

The invention has the beneficial effects as follows: bicycle lock and bicycle saddle are designed to integral body, do not influence the bicycle ride effects, lock body structure is simple, and convenient easy-to-use, reliability is high.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is described further.

Fig. 1 is the constructional drawing of normal operating condition of the present invention;

Fig. 2 is the constructional drawing that the present invention locks the car state;

Fig. 3 is that lock device of the present invention is locked timer-operated constructional drawing;

Constructional drawing when Fig. 4 is lock device release of the present invention.

1. lock bodies among the figure, 2. vehicle seat, 3. vehicle seat pole, 4. wheel, 5. vehicle seat pole torsion device, 6. fore shaft.

The specific embodiment

In constructional drawing shown in Figure 1, vehicle seat pole 3 is in normal angled, and lock body 1 inserts fore shaft 6, and with vehicle seat 2 common formation bike saddle parts, bicycle is in normal operating condition.

In constructional drawing shown in Figure 2, vehicle seat pole 3 is reversed 80 to 100 degree angles through vehicle seat pole torsion device 5, makes lock body 1 pass wheel 4 and inserts and fore shaft 6, and wheel 4 can not freely be rotated, and reaches lock bicycle effect.

In constructional drawing shown in Figure 3, lock body 1 inserts fore shaft 6, forms lock-out state.

In constructional drawing shown in Figure 4, lock body 1 does not insert fore shaft 6, forms released state.

Claims (2)

1. a bicycle lock comprises lock body (1), vehicle seat (2); Vehicle seat pole (3), wheel (4), vehicle seat pole torsion device (5); Fore shaft (6) is characterized in that, lock body (1) is connected vehicle seat (2) rear portion; Make vehicle seat pole (3) bending through vehicle seat pole torsion device (5) during the lock car, lock body (1) is passed wheel (4) insert fore shaft (6) formation Locking Device.

2. according to the said bicycle lock of claim 1, it is characterized in that, form lockup state when lock body (1) inserts fore shaft (6), form unlocking condition when lock body (1) is extracted fore shaft (6).
