Abstract

The invention discloses a lock rod structure of an automobile steering wheel lock, which comprises a lock catch and a lock body. A lock rod which can be inserted into the lock body is fixed on the lock catch; a lock rod sleeve is sleeved on the lock rod; and a ratchet which is matched with an elastic lock plunger in the lock body is arranged on the lock rod sleeve. As the lock rod sleeve is sleeved on the lock rod of the lock catch, and the position of the ratchet on the lock rod sleeve can be accurately determined according to the situation in which the lock catch is completely matched with the lock body but is not relevant to the error that the lock rod is fixed in the lock catch, thereby ensuring that the lock rod is locked when the lock catch is completely matched with the lock body, the purpose that a gap generated between the lock catch and the lock body is eliminated is achieved, a lock from can be prevented from being picked through the gap so as to improve the safety of the lock.

Description

A kind of Structure of lock rod of automobile steering lock

Technical field

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

Background technology

Existing T pattern handle lock such as Fig. 1, shown in Figure 2, it during vehicle steering, is to utilize snap close 1 and the circle ring of lock body 2 with bearing circle to grasp at lock, utilizes the locking bar 3 of band ratchet 4 on the snap close 1 to cooperate locking with locking bolt 5 on the lock body 2.When unblanking, locking bar 3 drives snap close 1 under the effect of pull back spring 6 separates with lock body.During locking, locking bar 3 cooperates with the locking bolt 5 of ratchet shape through the ratchet 4 on it, makes that locking bar 3 can only be to the motion of locking direction.Because be locked in when producing, locking bar 3 is to be fixed in the snap close 1 through extrusion process, there is error in the location of locking bar 3; Cause being locked in when using, when snap close 1 fitted like a glove with lock body 2, the end face of snap close 1 was positioned at the end face of a and lock body 2 and fits; Ratchet 4 on this hour locking lever 3 is positioned at b can not be just stuck by locking bolt 5, and snap close 1 must some distance of rollback could lock, and at this moment the end face of snap close 1 is positioned at a '; Ratchet 4 on the locking bar 3 is positioned at b ', causes producing between snap close 1 and the lock body 2 slit a ' a.If insert in this slit with instrument, be easy to lockset is destroyed.Therefore, there is potential safety hazard in the Structure of lock rod of existing automobile steering lock.

Summary of the invention

The object of the invention just provides a kind of Structure of lock rod of eliminating the automobile steering lock in slit when snap close and lock body are fitted like a glove.

Realize that the technical scheme that the object of the invention adopts is: the Structure of lock rod of automobile steering lock comprises snap close and lock body; Be fixed with the locking bar that can insert in the lock body on the snap close; Be with the locking bar cover on the said locking bar, said locking bar put be provided with lock body in the ratchet that matches of elasticity locking bolt.

The present invention is owing to be on the locking bar of snap close, to be with the locking bar cover; Situation when the ratchet position that locking bar puts can fit like a glove according to snap close and lock body accurately confirms, it doesn't matter to be fixed on error in the snap close with locking bar, what is no matter that is to say the length that locking bar stretches out snap close; In case the locking bar cover is enclosed within on the locking bar; The distance that all can guarantee ratchet and snap close end face on it is certain, thereby guarantees to be locked at snap close and the lock body hour locking lever that fits like a glove, and reaches to eliminate between snap close and the lock body slit purpose to occur; Can prevent to utilize this slit picking lock, improve the safety of lock.

The specific embodiment

Like Fig. 3, shown in Figure 4; The Structure of lock rod of automobile steering lock comprises snap close 1 and lock body 2; Be fixed with the locking bar 3 that can insert in the lock body 2 on the snap close 1, be with locking bar cover 7 on the locking bar 3, said locking bar cover 7 is provided with the ratchet 4 that matches with lock body 2 interior elasticity locking bolts 5.

Owing to be on the locking bar 3 of snap close, to be with locking bar cover 7; Situation when the ratchet position on the locking bar cover 7 can fit like a glove according to snap close 1 and lock body 2 is accurately confirmed; After being enclosed within locking bar cover 7 on the locking bar 3; All can guarantee on it ratchet 4 and snap close 1 end face be definite value apart from a to b, thereby guarantee to be locked at snap close and the lock body hour locking lever that fits like a glove, reach between elimination snap close 1 and the lock body 2 and the slit purpose occurs.

Use of the present invention:

Lock: see Fig. 5; Protecgulum on the lock body 2 is covered on the outer shroud 10 of vehicle steering, and make flat logical 8 to place on the instrument desk of operator's compartment, pushing snap close 1 closes up the identical outer shroud 10 with bearing circle of the end face of its end face and lock body 2 and holds tightly; Because locking bar 3 matches with lock body 2 interior elasticity locking bolts 5 by lock core 9 controls through the ratchet 4 on the cover locking bar cover 7 above that; Snap close 1 can only advance the puck, pushes snap close 1 more and locks tightly more, and lock combines firmly more with bearing circle.

Unblank: see Fig. 6,, drive elasticity locking bolt 5 and move downward the locking bar on the snap close 13 is discharged with key rotation lock core 9, under the effect of pull back spring, promote locking bar 3 drive snap closes 1 automatically and lock body opened in 2 minutes, lock can unload from bearing circle.

Claims

1. the Structure of lock rod of an automobile steering lock comprises snap close and lock body, it is characterized in that being fixed with on the snap close locking bar that can insert in the lock body, is with the locking bar cover on the said locking bar, said locking bar put be provided with lock body in the ratchet that matches of elasticity locking bolt.
