Safe anti-vibration bed

Abstract

A safe anti-vibration bed, including a bedside cylinder fixed at the center of two bedside frames, the outer ends of the piston rods of the two bedside cylinders are connected with lifting slides, and the two bedside frames are connected by their respective bedside cylinders. The head cylinder is divided into left and right parts with the same structure for the symmetrical axis. Each part includes the vertical rail, the half body of the lifting slide, the arched plate lifting and turning mechanism and the bed lifting mechanism. The vertical rail is fixed on the bedside frame and is close to the bedside cylinder. At the position of the lifting slide, the slider of the lifting slide can slide up and down along the vertical rail. The lifting and turning mechanism of the arch plate includes a U-shaped swing arm and a shaft sleeve fixed on the vertical rail. The lifting mechanism of the bed board includes a pull rod, a small rocker arm , Bed lifting swing arm, bed support. This kind of safe anti-shock bed, when a destructive earthquake occurs, the left and right arched plates are connected above the bed to form an arched protective barrier, and the bed plate falls to the bottom of the bed, and the people lying on the bed plate are less frightened and more humane. It is more suitable for the frail elderly.

Description

technical field [0001] The invention relates to a bed, more specifically to a safe anti-shock bed. Background technique [0002] General-purpose bed, just sleeps and has a rest for people, does not have anti-shock device, when earthquake occurs suddenly, because the people lying in bed are in sleep or relaxed state, without any preparation, will cause injury because of house collapse before escaping in time. In order to reduce the damage that earthquake causes to people as far as possible, the anti-vibration bed of different structure is disclosed successively in the publication. For example, the anti-vibration bed with the application number 03112117.9 mainly includes a bed body connected with two headboards, a shock-measuring device and a high-pressure pneumatic device installed in the bedside cabinet, and an air-supported piston and an air-supported piston are installed in the inner cavity of the bed body. The gear transmission device connected to the supporting piston, ...

Problems solved by technology

For example, the anti-vibration bed with the application number 03112117.9 mainly includes a bed body connected with two headboards, a shock-measuring device and a high-pressure pneumatic device installed in the bedside cabinet, and an air-supported piston and an air-supported piston are installed in the inner cavity of the bed body. The gear transmission device connected to the supporting piston, two arched plates connected with the gear transmission device, the arched plate is hinged to the longitudinal beam, and the longitudinal beam is hinged to the pillar installed on the bed body. When an earthquake or explosion occurs, the seismic The device outputs a control signal, connects the high-pressure pneumatic device, and pushes the piston rod of the air-supported piston to move outward. The outward movement of the piston rod drives two arched plates from the inner cavity of the bed body along the two sides of the bed body. Out and merged above the bed body to form the first layer of protective barrier, and at the same time, the two bed boards are stretched up and overturned together with the arched board to form the second layer of protective barrier. The protective barrier is supported by pillars. The disadvantages are: 1. In the formation In the process of protecting the barrier, the pillar also rotates with its fulcrum as the center of the circle, which will cause harm to the human body on the bed when it rolls down, and the safety is poor; The human body on the bed rolls down under the bed. On the one hand, it is inhumane, and on the other hand, for the frail and sick elderly, they will be hurt by falling
