Abstract

The invention relates to a cam lifting device for an examination bed. The cam lifting device comprises a universal wheel, wherein the wheel rod of the universal wheel is movably arranged inside a shell; a gland is fixed on the top part of the wheel rod; a spring is sleeved on the wheel rod; the upper end of the spring is contacted with the gland; the lower end of the spring is contacted with the shell; a shaft is movably arranged in the shell; the shaft is fixed with a cam; the cam surface of the cam is adhered to the gland; and one end of the shaft extends out of the shell and is connected with a pedal lever. The cam lifting device is applicable to the examination bed, makes the examination bed realize the moving and fixing functions, and prevents the examination bed from moving due to abrasion when the examination bed needs fixing.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cam lifting device used for an examination bed. Background technique [0002] Due to its special place of use, the examination bed must be able to move when receiving patients, and it must be fixed at a certain position when performing examinations. At present, most of the examination beds use universal wheels with foot brakes to realize this function. However, when the foot brakes of the universal wheels are worn, the examination bed will move during the examination, which will bring potential safety hazards to the examiners. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cam lifting device for an examination bed, which can enable the examination bed to realize the function of both moving and fixing, and will not cause the examination bed to move when it needs to be fixed due to wear and tear . ...
