Extendable hospital bed

Abstract

An extendable hospital bed comprises a bed frame for supporting a bed surface and bed legs arranged at two ends of the bed frame, wherein width extending frames and a bed head extending frame located at one end of the bed frame are arranged on the bed frame, the width extending frames are crossly and parellelly arranged along the bed frame, the bed frame, a middle width extending frame and the bed head extending frame are jointly laid to form the bed surface, a first hollow pipe is crossly arranged along the bed frame, a first inserting pipe which can be inserted into the first hollow pipe in a sliding mode is arranged on the width extending frames, a cross supporting bar is arranged on the width extending frames, one end of the cross supporting bar is connected to the width extending frames, the other end of the cross supporting bar is dragged to the bed frame, a second hollow pipe is longitudinally arranged along the bed frame, a third hollow pipe which is parallel to the first hollow pipe is arranged on the bed head extending frame, a second inserting pipe which is inserted into the second hollow pipe in a sliding mode is fixedly connected with the bed head extending frame, one end of a right angle bent inserting pipe is inserted into the third hollow pipe in a sliding mode, the other end of the right angle bent inserting pipe is inserted into an adjacent width extending frame longitudinal hollow pipe, the bed head extending frame is connected with a longitudinal support bar, one end of the longitudinal support bar is connected with the bed head extending frame, and the other end of the longitudinal support bar is dragged to the bed frame.

Description

technical field [0001] The invention relates to a hospital bed. Background technique [0002] The length and width of the bed surface of existing hospital bed all are fixed, and the movement of sick bed generally relies on the rolling of the wheel under the bed leg of sick bed. For a room where the door is not wide enough, the movement of the sick bed is limited by the width of the door. When the door was smaller than the width of the sick bed, the sick bed was difficult to move out or into the room. Especially when catastrophic accidents such as fires and earthquakes took place, the poor passage of sickbeds would endanger the lives of patients. [0003] In addition, during the sales and transportation of the hospital bed, although the general hospital bed has a folding structure, the width and total length of the hospital bed cannot be changed. raised. From the viewpoint of movement and transportation of the hospital bed, the size of the hospital bed needs to be reduced....

Problems solved by technology

[0004] However, from the point of view of use, patients have greater requirements for the length and width of the hospital bed, and require a larger size.

Moreover, hospital beds generally have
