Anti-shock bed

Abstract

The present invention relates to a shock-proof bed, including two bed heads, two bedside cupboard respectively equipped with high pressure pneumatic device and seismographic device and bed body jointed with two bed heads. Bed body includes bedsides and longitudinal-mounted two bed plates, in the internal cavity enclosed with bed plates and bedsides a pneumatic piston is mounted, the piston rod ofthe pneuamtic piston is hinged with gear connecting bar, said gear connecting bar is connected with two arched plate connecting bars by means of gear transmission mechanism, every arched plate connecting bar is hinged with arched plate, every arched plate respectively is hinged with a longitudinal beam, the longitudinal beam and its correspondent bed plate are fixedly connected and hinged with longitudinal beam connecting bar.

Description

technical field [0001] The invention relates to an anti-vibration bed. Background technique [0002] General-purpose bed, just sleeps and has a rest for people, does not have anti-vibration device, when earthquake occurs suddenly, because the people lying in bed are in sleep or relaxed state, without any preparation, will suffer fatal 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 structural forms is disclosed successively in the publication. Such as the anti-shock anti-vibration bed that the patent No. is 97246367.4 is made of size bedside, bed board, side of the bed, two invisible protective frames and two bedside tables, wherein a sensitive automatic device is housed in one of the bedside tables, and gas cylinders are housed in the other bedside table. When an earthquake occurs, the two invisible protective frames powered by air pressure rise ...

Problems solved by technology

Such as the anti-shock anti-vibration bed that the patent No. is 97246367.4 is made of size bedside, bed board, side of the bed, two invisible protective frames and two bedside tables, wherein a sensitive automatic device is housed in one of the bedside tables, and gas cylinders are housed in the other bedside table. When an earthquake occurs, the two invisible protective frames powered by air pressure rise rapidly, and the bed board descends to form a protective net for the human body. The disadvantage is that there is a wide gap between the protective nets formed by the two invisible protective frames. , cannot withstand the crushing and impact of heavy collapsed objects, so it cannot effectively avoid damage to the human body

The anti-vibration bed with the patent No. 01268749.9 includes a bed body. The inner box of the bed body is equipped with a gas cylinder and two gas-supported pistons powered by the high-pressure gas in the gas cylinder and controlled by a control switch. Each gas-supported piston It is connected with a connecting rod, and each connecting rod is connected with one of the two wings. When an earthquake or explosion occurs, the control switch will open the valve of the gas cylinder. Bottom, the bed inner box extends from both sides and forms an arched protective barrier above the bed body to block the collapsed objects falling from above. The disadvantages are: 1. Since the length of the general bed is 2 meters, The length of the protective barrier formed by the docking of the wings is also close to 2 meters, the span is long, and it is not strong. There is no synchronization in the process of side extension, and it cannot reach the top of the bed at the same time, so it is difficult to connect as a whole, so the protective barrier is unreliable
