Abstract

The invention discloses a cam connecting rod type fluted disc locking mechanism and a bed chair comprising the same. The mechanism comprises: a fluted disc which is arranged on a rotating device, wherein the rotating device is mounted on a mounting rack; a locking block which is arranged on one side of the fluted disc, wherein meshing teeth matched with the tooth part of the fluted disc are arranged at the free end of the locking block; a push rod, wherein one end of the push rod is connected with the locking block; and a cam handle, wherein the cam handle is connected with the other end of the push rod, the cam handle pushes the push rod to move back and forth when rotating, and the push rod drives the locking block to act, so that the free end of the locking block is close to or far away from the tooth part of the fluted disc. The cam handle is rotated to drive a connecting rod structure to control the rotary fluted disc to be meshed and locked, and the locking mechanism is simple in structure, low in cost and long in service life.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cam-link type chainring locking mechanism and a bed chair containing the same. Background technique [0002] Nowadays, high-end multifunctional beds and chairs require the bed surface to have an integral rotation function, which is convenient for beauticians and doctors to use, and at the same time increases the scope of application of the product. After the rotation is completed, it is necessary to utilize a locking mechanism to keep the bed and chair from rotating, so as to ensure the safety of consumers. The methods commonly used in the existing bed and chair rotation locking mechanisms are: pin and hole locking, the locking mechanism has a limited adjustable angle; electromagnetic locking, which can be adjusted at any angle, but the cost is high and installation and maintenance are difficult; the friction plate Locking can be adjusted at any angle, but the cost is ...
