Abstract

The invention relates to a cam locking device which comprises a handle, wherein one end of the handle is provided with a cam which is movably arranged on a connecting shaft, a pressure cover which is matched and contacted with the cam is also arranged on the connecting shaft, two symmetrical downward first inclined planes are arranged on the upper end face of the cam, and second inclined planes which are matched with the first inclined planes are arranged in the pressure cover. The cam locking device is simple in structure, the handle is connected with the cam, the handle is rotated to drive the cam to rotate so that the cam is contacted with different parts in the pressure cover, the steps of jacking and descending the pressure cover are realized, the angle adjustment of the cam is realized, and moreover, a sphere is arranged on the other end of the handle, so that the handle can be conveniently held by a hand and is not easily slipped.

Description

technical field [0001] The invention relates to a cam self-locking device used in the field of medical instruments. Background technique [0002] Generally, the headboard of the operating bed can only be adjusted in one direction, but sometimes the one-way adjustment cannot adjust the patient to a suitable angle during the operation, which is convenient for the operation, so the two-way adjustment of the headboard came into being, and the following It is how to quickly and conveniently realize the angle adjustment of the two-way adjustment head plate. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a cam locking device, which has a simple structure, is convenient to operate, and can quickly realize angle adjustment. [0004] The technical solution adopted by the present invention to solve the technical problem is: a cam locking device, including a handle, a cam is provided at one end of the handle, and th...
