Directional steering locking mechanism with automatic return function

Abstract

The invention discloses a directional steering locking mechanism with the automatic return function. The directional steering locking mechanism comprises a steering assembly, a self-locking handle, a gas spring and an instrument stand. The gas spring is connected between the steering assembly and the instrument stand. The upper end of a gas spring rod is connected with the self-locking handle. The self-locking handle controls a self-locking needle valve in the gas spring. When the self-locking handle is lifted up, the steering assembly is in an adjustable state and can be adjusted at will between the nearest position and the farthest position. When the self-locking handle is laid down, the position of the steering assembly is fixed and the steering assembly can further be locked. The directional steering locking mechanism with the automatic return function is reasonable in design and simple in structure, existing complex structures like a double-thread sleeve and a lock bolt are omitted, processing and operating are made simpler and faster, and adjustment is more accurate and reliable.

Description

technical field [0001] The invention relates to a steering system of a forklift, in particular to a steering locking mechanism with an automatic return function. Background technique [0002] As an important logistics transportation tool in today's modern industrial production, forklifts have higher and higher requirements for the comfort and convenience of the whole machine as the application fields become more and more extensive. The steering control device of an internal combustion forklift is mainly composed of steering column, steering gear, steering wheel, steering bracket, locking mechanism and other components. Due to the different heights of operators, the installation of the control system cannot be fixed at a certain position. Choose a comfortable position according to the height, arm length and other characteristics to avoid driving fatigue. see Image 6 , the existing forklift steering assembly 9 is complex in structure, especially the steering wheel position a...

AI Technical Summary

Problems solved by technology

The above-mentioned locking mechanism has the following defects: (1) It is difficult to process and manufacture, and the structure is not compact and not beautiful; (2) It needs more than two turns to lock by rotating the thread, which is inconvenient and time-consuming to operate; (3) It cannot be automatically locked. Back to the position, the steering wheel often hits the driver's body due to tilting during operation
