Abstract

The utility model relates to a shackle type anti-theft lock of an autobicycle, which comprises a main lock body and an auxiliary lock body which are formed from carbon steel materials after the heat treatment, the shape of an inner frame, which is formed from together locking the main lock body and the auxiliary lock body, is the same with the section of a wheel, and the wheel is compactly surrounded by the inner frame, and no gap exists between the wheel and the inner frame. With the technical proposal, after the main lock body and the auxiliary lock body are together locked and compactly connected, the wheel is compactly surrounded, the shape is like an ancient shackle, thereby the lock body can not be damaged by lawless persons, and the knocking impact is very effectively prevented, and the lock body being cut off by a hydraulic pressure clamp is avoided, and the lock has the anti-sawn and the tamperproof functions.

Description

The shackle-type anti-theft lock for motorcycle

Technical field:

The utility model relates to the anti-theft device for vehicle technical field, refers in particular to a kind of shackle-type anti-theft lock for motorcycle.

Background technology:

Existing motorcycle anti-theft lock construction remains in number of drawbacks, and the lawless person is easy at short notice instrument such as to cut with hammer or hydraulic pressure lock body is destroyed, and therefore, the motorcycle drop-out time takes place again and again, has caused loss for people's property.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, and the shackle-type anti-theft lock for motorcycle of a kind of safe, anti-hammering, shearing-proof is provided.

For achieving the above object, the technical scheme that the utility model provides is: include main lock body and the auxiliary lock body made after the carbon steel material heat treatment, main lock body and auxiliary lock body close that the lock back forms the shape of inside casing identical with the wheel cross section, and wheel closely can be surrounded, seamless between wheel and the inside casing.

The upper and lower surface that described main lock body and auxiliary lock body close the framework behind the lock forms the inclined-plane.

Lock core on the described main lock body is an atomic structure.

After the utility model adopts technique scheme, after main lock body and attached lock body close lock, closely connect, wheel is closely surrounded, likeness in form chains in ancient times make the lawless person carry out malicious sabotage to lock body, prevent to beat impact very effectively, prevent that hydraulic tongs from cutting off lock body, anti-sawed-off, pick-proof is broken.

Description of drawings:

Fig. 1 is the utility model plane structure schematic diagram;

Fig. 2 is the utility model perspective view.

The specific embodiment:

The lock body of present embodiment is by the main lock body of making after the carbon steel material heat treatment 1 and auxiliary lock body 2 two parts group layers, topmost characteristics are, main lock body 1 and auxiliary lock body 2 close that the lock back forms the shape of inside casing 3 identical with the wheel cross section, and wheel closely can be surrounded, seamless between wheel and the inside casing 3.Above-mentioned design makes instrument such as hydraulic tongs to stretch in the space, also just can't cut off, sawed-off, destruction such as sled is bad.The upper and lower surface that described main lock body 1 and auxiliary lock body 2 close the framework behind the lock forms inclined-plane 4,5, and this inclined-plane 4,5 makes that hammer can't the application of force when being subjected to hammer and impacting, and lock body just can not smashed yet.Be equipped with prior art atom lock core structure commonly used simultaneously on the main lock body 1 of this example, make that the utility model safety is higher.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
