Description

Automobile steering wheel theftproof lock

The utility model relates to a kind of lock, especially a kind of anti-theft column lock of bearing circle vehicle.At present, particularly the stolen phenomenon of automobile is quite serious for power actuated vehicle.Stolen for preventing vehicle, existing multiple automobile anti-theft lock mainly contains electronic type anti-theft column lock and mechanical antitheft lock on the market, and electronic type anti-theft column lock cost height is installed complicated; The mechanical antitheft lock cost is low, as automobile steering lock, the lockset of this structure is to utilize the rotation that limits bearing circle to reach the purpose of locking, but the existing automobile steering lock pair card dual-handle structures that adopt more, its complex structure, heaviness, cost height, inconvenient in the use, it is bigger particularly to lock post gap, and the factor that is subject to outside destroy is higher.

The purpose of this utility model provides a kind of simple in structure, pick-proof, anti-hammer performance is strong, and cost is low, and is aesthetic in appearance, automobile steering wheel theftproof lock tool easy to install.

The utility model is made up of lock body, tapered end, locking bar etc., lock body is a hollow tube, its outside is welded with a U type pipe, locking bar one end is provided with more piece circular cone build tooth, the tooth end is provided with the collar and spring cotter, in case locking bar pulls from lock body, the other end of locking bar is welded with U type pipe, tapered end is made up of lock housing, dead bolt, spring, lock core, dead bolt (5) is stuck in the tapered teeth groove of locking bar (3), and the bottom is withstood by spring, and semi-circular locking bolt is inserted in the groove of dead bolt, tapered end is enclosed within an end of lock body, and locking bar runs through in the hollow tube that tapered end is inserted in lock body.

The utility model has the advantages that: simple in structure, cost is low, and is easy to operate; Locking bolt is provided with hiddenly in the core, and external force is difficult to act on it, and pick-proof, anti-to dial performance good; The dead bolt bottom is under the effect of spring, and dead bolt top failure-free blocks the locking bar teeth groove, and safety is good; Lock body is with outward to apply moulds layer, aesthetic in appearance.

Below in conjunction with drawings and Examples structure of the present utility model is further described.
