Description

Circular lock for motorcycle

The utility model relates to a kind of lock for motorcycle, particularly a kind ofly can pin the antitheft circular lock for motorcycle of wheel.

At present, lock for motorcycle is based on the free-standing lock, it pins wheel with it when parking motorcycle, reaches antitheft purpose, owing to can't be fixed on the car body, carry difficulty, lose when driving easily, circular lock mainly is used on the bicycle, is fixed on the vehicle frame, by the circular hollow lock tube, the annular lock pin, tapered end, compositions such as back-moving spring, tapered end is fixed on the lock tube, and back-moving spring is connected between lock pin and lock tube, and the lock pin rear end offers bayonet socket and cooperates with tapered end, when sealed, the lock pin front end passes through the lock tube opening, and lock pin blocks the location by tapered end, because tapered end is to pin the lock pin rear end, far away apart from the lock tube opening, it is short that the lock pin front end inserts lock tube length, omnidirectional spacing, when pressed by external force collision or sled, crooked easily dislocation of lock pin and unhook, theftproof performance is relatively poor.

The purpose of this utility model is to have shortcoming that a kind of improved garden shape lock for motorcycle is provided for overcoming above-mentioned prior art, can be fixed on the car body, and easy to use, theftproof performance is better.

The purpose of this utility model can realize by following measure: this lock has the hollow lock tube of garden arc, on lock tube, offer the handgrip movement joint, lock pin and back-moving spring are housed in the lock tube, the lock pin rear end links to each other with back-moving spring, the lock pin rear portion is provided with handgrip, the front portion is provided with the dead bolt bayonet socket, and the lock pin socket end of lock tube is provided with tapered end, tapered end control dead bolt.In use, as long as catch handgrip to push away lock pin movement, inject pin tongue bayonet socket location by dead bolt behind the anterior reeve of the lock pin lock tube socket, at this moment handgrip also is against its movement joint end, and lock pin and lock tube have formed the closed-loop structure of two-way location; Make dead bolt deviate from bayonet socket with key rotation tapered end when unblanking, the back-moving spring lock pin resets.

Concrete structure of the present utility model and embodiment are provided by the following drawings:

Fig. 1 is circular lock for motorcycle unlocking condition longitudinal sectional drawing;

Fig. 2 is the sealed shape longitudinal sectional drawing of circular lock for motorcycle;

Below with reference to accompanying drawing the utility model is done to be described in detail by a step: with reference to Fig. 1, lock tube ［ 1 ］ is the circular arc hollow-core construction, lock pin ［ 3 ］ and back-moving spring ［ 7 ］ are contained in the lock tube ［ 1 ］, the lock pin rear end back-moving spring ［ 6 ］ that joins, front end is conical, and lock pin ［ 3 ］ rear portion is provided with handgrip ［ 5 ］, the front portion is provided with spill dead bolt bayonet socket ［ 2 ］, lock pin is the concentric cylinder of lock tube, can be along the lock tube activity, lock tube in handgrip ［ 5 ］ scope of activities has crack ［ 4 ］, handgrip when sealed ［ 4 ］ is near ［ 4 ］ one ends that crack, tapered end ［ 7 ］ is located at the lock pin socket end of lock tube ［ 1 ］, tapered end has dead bolt ［ 10 ］, pin core ［ 9 ］ and spring ［ 11 ］ for the ease of installing, can be provided with fixed head ［ 6 ］ on lock tube.As long as lock pin is pushed and plugged in the lock tube socket tapered end, more can pin the location, see Fig. 2, this lock can be installed on the motorcycle according to user's selection and use, such as being installed on the wheel guard.

Of the present utility model simple in structure, reasonable in design, utilize tapered end to pin the lock pin front end in circular arc lock tube socket, handgrip withstands the lock tube circular arc other end, forms two-way location closed-loop structure, has improved the anti-damage ability of lock, sturdy and durable, with low cost, easy to install and use, be a kind of theftproof lock of practicality.
