Lifesaving bed for earthquake occurrence

Abstract

The invention relates to a lifesaving bed for earthquake occurrence. The lifesaving bed comprises a trigger and a bed body, wherein a mattress is horizontally placed in a cavity of the bed body; a pulley and a lock catch are arranged in the upper part of a back board of the bed body, respectively, and thrust springs are arranged on two sides of the back board of the bed body below the lock catch and the pulley, respectively; the middle section of the lower part of the back board of the bed body is connected to one side of a corresponding folding cover plate through a hinge; an elastic ropewinder is placed at one end in the behind bottom in the cavity of the bed body; the elastic ropewinder rolls one end of a pull rope while the other end of the pull rope bypasses the pulley in the upper part of the back board of the bed body and extends outward; the tail end of the extending pull rope is fixed on a paved surface outer hanging ring of the folding cover plate behind, and teeth of outer gear heads and teeth of double gear heads are embedded into corresponding outer chain tooth holes, respectively; and the trigger is connected to the below elastic ropewinder in the rear part in the inner cavity of the bed body through a steel stay wire.

Description

technical field [0001] The invention relates to a bed, in particular to a lifesaving bed used when an earthquake occurs. Background technique [0002] Earthquake is one of the irresistible natural disasters of human beings. At present, there is no life-saving device specially used for earthquakes in the world. The prediction of the earthquake prevention department is the only scientific means nowadays. The existing scientific and technological means still cannot Before the accurate prediction of the earthquake zone, escape and self-rescue are particularly important. At home and abroad, there are too many cases of huge losses caused by earthquakes. Contents of the invention [0003] In order to overcome the existing deficiencies in the escape process when an earthquake occurs, the present invention provides a life-saving bed used when an earthquake occurs. The trigger of the life-saving bed adopts the principle of a seismograph, which can Open the life-saving device in th...
