Liftable medical bed

Abstract

The invention discloses a liftable medical bed. The liftable medical bed comprises an underframe, an upper frame, shear-fork type lifting devices and a driving device, the left and right sides of theunderframe and upper frame are respectively provided with first sliding rails, a second sliding rail is arranged between the two first sliding rails of the upper frame; the shear-fork type lifting devices are arranged between the underframe and the upper frame, and the two shear-fork type lifting devices are respectively arranged on the left and right sides of the underframe and the upper frame; the driving device comprises a support seat, a lead screw, a handle and two lead screw nuTS; the support seat is fixed on the upper frame, the two lead screw nuTS are arranged on the second sliding rail and slide along the second sliding rail, and the two lead screw nuTS are connected with the shear-fork type lifting devices at the left and right sides; the left side of the lead screw is provided with a left rotating thread, the right side of the lead screw is provided with a right rotating thread, the lead screw passes through the two lead screw nuTS and the support seat and is connected withthe handle, and the lead screw rotates to make the two lead screw nuTS move to the opposite direction on the second sliding rail. The liftable medical bed has the advantages that the structure is ingenious, the practicability is strong, and the medical bed can be lifted upward and downward.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a liftable medical bed. Background technique [0002] At present, the sick beds used in the hospital all have the function of lifting up and down, and the lifting function of the sick bed all adopts a screw thread propeller, a motor, and an oil cylinder to push the sick bed up and down. The structure is complicated, the cost is high, and the practicability is poor. Contents of the invention [0003] In view of this, the present invention proposes a liftable medical bed, so that the medical bed can be lifted up and down. [0004] On the one hand, the present invention provides a liftable medical bed, comprising a bottom frame, an upper frame, a scissor lifting device, and a driving device. First slide rails are respectively arranged on the left and right sides of the bottom frame and the upper frame. A second slide rail is arranged between the first slide rails; the s...
