Electric locking mechanism of shock absorption device for medical bed

Abstract

The invention provides an electric locking mechanism of a shock absorption device for a medical bed. The electric locking mechanism comprises a shock absorption outer cylinder, an oil return pipeline,an oil return check valve, an oil return solenoid valve, an oil discharge pipeline, an oil discharge check valve, an oil discharge solenoid valve, a piston, a piston rod, a baffle plate, a cushioningspring, and a sealing ring, wherein the piston is arranged in the shock absorption outer cylinder and is used for dividing the interior of the shock absorption outer cylinder into a first cavity anda second cavity; the two ends of the oil return pipeline are respectively in communication with the first cavity and the second cavity; the oil return check valve and the oil return solenoid valve areconnected to the oil return pipeline in series; the two ends of the oil discharge pipeline are respectively in communication with the first cavity and the second cavity; the oil discharge check valveand the oil discharge solenoid valve are connected to the oil discharge pipeline in series; the piston is connected to the piston rod; and the cushioning spring is arranged on the piston rod in a sleeving manner. The electric locking mechanism solves the problems of complicated operation and insufficient stability of the locking mechanism of the shock absorption device in the prior art.

Description

technical field [0001] The invention relates to the technical field of medical beds, in particular to an electric locking mechanism of a shock absorbing device for a medical bed. Background technique [0002] Driven by market demand, a large number of medical beds with shock-absorbing devices have appeared. Medical beds with shock-absorbing functions increase the comfort of patients while reducing the stability of the bed during the process of transporting patients. When the bed surface of the medical bed with shock absorption function is subjected to impact pressure, the bed will move downward, and when the pressure decreases or disappears, the bed will move upward; Shake up and down. When the patient is being treated on the hospital bed (such as during cardioresuscitation), if the hospital bed has a shock-absorbing function, the bed will shake up and down, which is not conducive to treatment. In this usage scenario, the shock-absorbing function of the hospital bed is not ...
