Linear sliding mechanism

Abstract

The invention discloses a linear sliding mechanism which comprises an inner column, an outer column and a linear driving mechanism. The periphery of the inner column is sleeved with the outer column,the inner column and the outer column do relative linear motion in the axial direction under the effect of the linear driving mechanism, a limiting sliding mechanism is arranged between the inner column and the outer column, the limiting sliding mechanism is composed of an inner column limiting sliding mechanism and an outer column limiting sliding mechanism, the inner column limiting sliding mechanism is fixedly arranged at the end of the inner column, the inner column limiting sliding mechanism is in contact and sliding fit with the inner wall of the outer column, the outer column limiting sliding mechanism is fixedly arranged at the end of the outer column, and the outer column limiting sliding mechanism is in contact and sliding fit with the outer wall of the inner column. Since the limiting sliding mechanism is arranged between the inner column and the outer column, limiting is achieved through cooperation of the inner column limiting sliding mechanism and the outer column limiting sliding mechanism, and mutual movement of the inner column and the outer column is more stable, reliable and smooth in sliding under the effect of the linear driving mechanism.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a linear sliding mechanism suitable for instrument carts used in hospital nurse stations, testing centers, imaging centers and other departments. Background technique [0002] Due to the lack of a limit support structure between the two relatively sliding parts in the existing linear sliding mechanism, when there is an installation gap between the two parts, the stability during the sliding process is not high, and there is a phenomenon of radial swing, and After sliding for a long time, the internal structure of the component is deformed due to the swing, which further affects the smoothness of sliding. Contents of the invention [0003] The purpose of the present invention is to provide a linear sliding mechanism capable of making the linear motion stable and reliable and sliding smoothly in view of the above existing problems. [0004] The technical so...
