Steering column locking device

Abstract

The invention provides a steering column locking device, which can prevent the influence on the appearance of an operation knob, can avoid increasing the cost of manufacturing the device and can prevent spending much time assembling. A knob base (15) of the steering column locking device (10) comprises a slot and a blocking slot, wherein an operation knob (16) is detachably arranged in the slot along a detaching direction (P) vertical to a rotating shaft (R); the operation knob is blocked in the blocking slot; the operation knob comprises a handle (21) which is held by an operator, a claw which is connected to the handle, arranged in the slot of the knob base and is matched with the blocking slot, a pushing extending part (45) which is integrally arranged together with the claw and can be pushed along the direction crossing with the detaching direction, so as to relieve the blocking state between the claw and the blocking slot.

Description

technical field The invention relates to a steering column locking device. Background technique In the prior art, for example, a steering column locking device is known with the following structure, which includes: a base, which is fixed on the lock cylinder and has an opening opening toward the keyhole of the lock cylinder; an operating knob, which can To be mounted on or detached from the base, the operating knob includes an operating hole for inserting the mechanical key (for example, Refer to Patent Document 1). In addition, in the prior art, for example, people also know a steering column locking device having the following structure, which includes: a base, which is fixed on the lock cylinder and has an opening opening toward the keyhole of the lock cylinder; a connecting part, It can be mounted on or detached from the base; the operation knob, due to the joint part can be mounted on or detached from the base, and the operation knob is mounted to the on the base (f...

AI Technical Summary

Problems solved by technology

The connecting member should not only be provided with the protruding button portion, but also be provided with an engaging portion for engaging with the base, and a leaf spring for applying elastic force to the connecting member should also be installed, so that the connecting member will be distorted. Problems where structures and shapes become more complex

In addition, in order to attach or detach the operation knob to or from the base, it is necessary to use a connecting member and a leaf spring, so that the number of parts of the locking device increases and its manufacturing cost also increases.
