Description

Improved automobile steering lock

Technical field

The invention belongs to lockset, particularly a kind of improved automobile steering lock.

Background technology

Stolen for preventing automobile, automobile steering lock is practical and convenient lock commonly used, has at present the product of multiple different structure, no matter that a kind of lock has its deficiency.Its internal diameter size with bonnet on the protecgulum on the lock body of bearing circle outer shroud parcel and the snap close is certain in these locks, and the kind of vehicle steering and specification are numerous, the size of outer shroud differs, so that the lock before, internal diameter after bonnet is involutory is greater than or less than the external diameter of bearing circle outer shroud, between loosening or lock body and the snap close larger gap is arranged after causing locking, be locked on the bearing circle the loosening stop bit parts that rotate easily and lose position-limiting action to bearing circle, produce the larger easy insertion tool in gap between lock body and the snap close and will lock destruction, therefore, no matter which kind of situation all affects the anti-theft of lock.

Summary of the invention

The purpose of this invention is to provide all kinds of vehicle steerings of a kind of adaptation, the better improved automobile steering lock of theftproof performance.

Solution of the present invention is: improved automobile steering lock, comprise lock body and snap close, and described lock body is provided with: outward extending stop bit parts, tapered end, the protecgulum that coincide with the bearing circle outer shroud; Described snap close is provided with: the locking bar that cooperates with locking mechanism in the lock body, the bonnet that coincide with the bearing circle outer shroud; The locking bar of snap close inserts along stop bit parts direction in the lockhole of lock body and the lock body bearing fit, and protecgulum is corresponding with bonnet can be involutory; The inner face of described protecgulum and bonnet is provided with liner.

Described snap close is provided with the loudspeaker pressing plate.

Lock Lee of the present invention is fixed on the vehicle steering outer shroud with the protecgulum on lock body and the snap close and bonnet, and cooperating with locking bar in the snap close by the locking mechanism in the lock body will be locked, make the stop bit parts fixedly positioning to limit the rotation of bearing circle.Because the inner face of protecgulum and bonnet is provided with liner, can can take out and place according to the size of vehicle steering outer shroud, make protecgulum and bonnet can both with the bearing circle outer shroud well mutually, to guarantee that the present invention's lock has preferably fixed effect to all vehicle steerings, elimination is locked in the phenomenon that occurs loosening not tight or excessive slit when locking on the bearing circle, improves the anti-theft of lock.Loudspeaker pressing plate on the snap close can be pressed on the loudspeaker of bearing circle when locking, and when the moving lock of people was arranged, the loudspeaker pressing plate played alarm function with the pressure touch loudspeaker.

Adopt the present invention's lock of said structure, have all kinds of vehicle steerings of adaptation, the better advantage of theftproof performance.

The invention will be further described below in conjunction with accompanying drawing.

Description of drawings

Accompanying drawing is structural representation of the present invention.

The specific embodiment

See accompanying drawing, improved automobile steering lock comprises lock body 5 and snap close 9, the protecgulum 3 that is consolidated with outward extending shaft-like stop bit parts 10 on the lock body 5, is provided with locking mechanism and coincide with bearing circle outer shroud 1; Be consolidated with locking bar 4 on the snap close 9, be provided with the bonnet 2 that coincide with bearing circle outer shroud 1; Locking bar 4 on the snap close 2 inserts along stop bit parts 10 directions in the lockhole of lock body 5 and lock body 5 bearing fits; Locking mechanism adopts prior art, comprises tapered end 6, and the lock core control lock pin in the tapered end 6 cooperates (not shown) with locking bar 4; Protecgulum 3 is corresponding with bonnet 2, can be involutory with bearing circle outer shroud parcel when locking, and the inner face of protecgulum and bonnet is provided with liner 7, is hinged with the loudspeaker pressing plate 8 with stop bit parts 10 approximate vertical on the snap close 9.

Use of the present invention, lock: the protecgulum 3 on the lock body 5 is covered on the outer shroud 1 of vehicle steering, and stop bit parts 10 are placed on the instrument desk of operator's compartment, pushing snap close 9 make the protecgulum 3 of bonnet 2 and lock body 5 on it involutory with bearing circle outer shrouds 1 parcel and hold tightly, simultaneously loudspeaker pressing plate 8 is pressed on the loudspeaker, at this moment stop bit parts 10 are fixedly positioning on bearing circle, bearing circle can not arbitrarily rotate under the stopping of instrument desk, reach antitheft purpose, larger such as bearing circle outer shroud 1 diameter, the liner 7 in protecgulum 3 and the bonnet 2 can be taken off; If violence is unblanked, will make loudspeaker pressing plate 8 touch loudspeaker and play alarm function.Unblank: use key rotation lock core, locking bar 4 is released, and snap close 9 can separate with lock body 5, behind the bearing circle unload lock, loudspeaker pressing plate 8 can be drawn in.
