Abstract

The utility model relates to a laterally-operated folding bed for civilian use. The utility model solves such problems that the prior electric or pneumatic medical bed is complex in terms of the lifting mechanism, inconvenient for maintenance and unsuitable for civilian use. The bed is characterized in that the bed surface framework is divided into two types: fixed and movable; a lifting device is arranged on the back of the movable framework, a worm gear transmission mechanism arranged on a vertical frame under the bed is used to drive a worm shaft to rotate so as to wind a pull rope on the shaft, the steel rope is pulled so that the lifting device is lifted upwards so as to lift the framework up or down; the lower half part movable bed surface framework is lifted upwards by pushing a vertical rod arranged on the bottom surface of the movable framework to rotate around a hinge through a screw transmission device on the vertical frame, thereby leading a person to half-sit on the bed surface without gliding downwards. The utility model has the advantages of simple structure, labor saving, firm location and easy operation and the like, and can be widely used in hospitals, hotels and even daily life.
