Lock rod structure of automobile steering wheel lock

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

technical field [0001] The invention belongs to locks, in particular to a lock bar structure of an automobile steering wheel lock. Background technique [0002] Existing T-type steering wheel lock such as figure 1 , figure 2 As shown, when locking the steering wheel of a car, it uses the lock catch 1 and the lock body 2 to hold the ring of the steering wheel, and utilizes the lock bar 3 with the ratchet 4 on the lock catch 1 and the lock bolt 5 on the lock body 2 Mate lock. When unlocking, the lock bar 3 drives the lock catch 1 to separate from the lock body under the action of the return spring 6 . When locking, the lock bar 3 cooperates with the pawl-shaped lock bolt 5 through the ratchet 4 thereon, so that the lock bar 3 can only move in the locking direction. When the lock is in production, the lock rod 3 is fixed in the lock catch 1 by die-casting process, and there is an error in the positioning of the lock rod 3. As a result, when the lock is in use, when the loc...

AI Technical Summary

Problems solved by technology

When the lock is in production, the lock rod 3 is fixed in the lock catch 1 by die-casting process, and there is an error in the positioning of the lock rod 3. As a result, when the lock is in use, when the lock catch 1 and the lock body 2 are completely matched, the end surface of the lock catch 1 The position at a fits the end face of the lock body 2. At this time, the ratchet 4 on the lock lever 3 is located at b and cannot be just locked by the lock bolt 5. The lock catch 1 must retreat a little distance to lock. At this time, the end face of the lock catch 1 At a', the ratchet 4 on the lever 3 is at b', resulting in a gap a'a between the catch 1 and the lock body 2

If a tool is inserted into the gap, it is easy to destroy the lock

Therefore, there is potential safety hazard in the lock bar structure of existing automobile steering wheel lock
