Description

Three use anti-theft vehicle lock

The utility model relates to a kind of anti-theft device, particularly relates to a kind of three and uses anti-theft vehicle lock.

Along with expanding economy, the raising of living standards of the people, the user of power assist vehicle, bicycle is more and more, so the stolen of vehicle is on the rise.Existing theftproof lock all can not effectively prevent burglar's theft on function, structure, material.

It is good that the utility model provides a kind of theftproof performance, both can self-locking, and can rely on thing to lock together with the external world again, what can be used as that inflator uses simultaneously again three uses anti-theft vehicle lock.

To achieve these goals, what the utility model provided three uses anti-theft vehicle lock, and it is made up of fixed system, central siphon, expansion link, lock ring tapered end;

It is characterized in that being provided with expansion link in the above-mentioned described central siphon;

When vehicle is tightly locked with extraneous dependence thing, pull out expansion link; During the vehicle self-locking, expansion link is placed in the outer central siphon;

When tire unsaturated vapor or generation gas leakage, central siphon and expansion link can be made inflator and use.

What the utility model provided three uses anti-theft vehicle lock, is a lock, but self-locking and tightly lock with the extraneous thing that relies on is again an inflator simultaneously.Three usefulness anti-theft vehicle locks that the utility model provides on structure, function be common lock can't be obtained.Be provided with single tight bolt, bearing pin, cross joint on above-mentioned described fixed system, when vehicle relied on thing tightly to lock with the external world, the thief can't move vehicle.Above-mentioned described lock ring is connected into by pitch chain, and it can lock together with dependence thing in irregular shape.The material that the three usefulness anti-theft vehicle locks that the utility model provides adopt is a mild steel, makes that the toughness of lock is better, not easy fracture.In order to strengthen surface strength, prevent to be cut off by the thief, lock has carried out the face carburizing, and the three usefulness anti-theft vehicle lock theftproof performances that make the utility model provide are stronger.

The function and the structure of the inflator part of the three usefulness anti-theft vehicle locks that the utility model provides are identical with inflator commonly used.

Fig. 1 is the structural representation of an embodiment of the antitheft car of three usefulness described in the utility model;

Fig. 2 is the structural representation of the tight bolt of fixed system list of the antitheft car of described three usefulness of Fig. 1.

Below in conjunction with accompanying drawing, the embodiment that the utility model is provided is described in detail.

Fig. 1 is the structural representation of an embodiment of three usefulness anti-theft vehicle locks described in the utility model.As shown in the figure, this three usefulness anti-theft vehicle lock comprises fixed system 1, central siphon 2, expansion link 5, lock ring 3, tapered end 4.Common lock is not provided with single tight bolt at fixed system.The three usefulness anti-theft vehicle locks that the utility model provides are provided with single tight bolt A in fixed system, prevented that vehicle from being unloaded lock by the thief when tightly locking with extraneous dependence thing and stealing car.The schematic diagram of single tight bolt is Fig. 2.Common lock does not have expansion link.The three usefulness anti-theft vehicle locks that the utility model provides are provided with expansion link 5 in the central siphon 2 outside, when vehicle is locked with the external world is tight, pull out expansion link 5, put lock ring on the spot the dependence thing, lock by tapered end.Be provided with gas-tpe fitting P on connecting axle D, when tire unsaturated vapor or tire generation gas leakage, the gas-tpe fitting P other end and tire on valve inside U one termination joined, branched knot X twitches expansion link 5 back and forth as inflator handle, reaches the purpose to the tire gas transmission.The shape of above-mentioned described tapered end, function are identical with common tapered end.The tracheae of inflator can unload, and also its solid locking can not influenced travelling of vehicle.

Concerning one of ordinary skill in the art, embodiment of the present utility model can do multiple variation.

For example:

1. expansion link can be arranged on the central siphon outside;

2. central siphon and expansion link can be as inflators.

Claims (2)

1. use anti-theft vehicle lock for one kind three, it by fixed system, central siphon, expansion link, lock ring, tapered end, form;

It is characterized in that being provided with expansion link in the above-mentioned described central siphon;

2. as claimed in claim 1 three use anti-theft vehicle lock, it is characterized in that being provided with only with the tight bolt of the fastening list that can not relax in the said fixing system.
