UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the back plate cannot move in prior art, and easily brings the shortcoming of very strong compression to patient, and proposes a structure that improves back plate to patient's back compression when medical bed back lifting.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A structure that improves back plate to patient's back compression when medical bed back lifting, including center seat board and back plate assembly, center seat board and back plate assembly are connected through hinge;

[0007] Back plate assembly includes frame and movable back plate, is provided with a pair of slide beams in frame, is provided with sliding block on slide beam, and sliding block can reciprocate on slide beam towards the direction of center seat board, and sliding block and movable back plate are fixedly connected;

[0008] Still be connected with support frame on slide beam, be connected with electric push rod on support frame, and electric push rod is connected with bed body mainboard, and bed body mainboard is connected with center seat board, and after the opening of electric push rod, drive back plate assembly rotates along hinge and lifts back plate assembly.

[0009] Preferably, sliding block and slide beam are further connected with spring, and the spring is in the tensile state when the movable back plate slides away from the center seat plate.

[0010] Preferably, a plurality of ventilation holes are provided on the center seat plate, and the ventilation holes are downwardly extended to form reinforcing rib holes.

[0011] Preferably, a plurality of reinforcing rods are provided between the movable back plate and the frame. ADVANTAGEOUS EFFECTS

[0012] After the electric push rod is opened, the driving back plate assembly is rotated along the hinge, so as to lift the back plate assembly. After the back plate assembly is lifted, the movable back plate is driven by the patient's back to slide upward, so as to eliminate the friction and compression between the patient's back and the movable back plate. BRIEF DESCRIPTION OF DRAWINGS
