Abstract

The invention discloses a stretcher compartment which comprises two parallel arc-shaped rails and a compartment body, wherein arc-shaped sliding rails are arranged on the side surfaces of the arc-shaped rails, arc-shaped sliding plates are arranged on the two sides of the back of the compartment body respectively, a plurality of sliders or pulleys are arranged on the inner sides of the arc-shaped sliding plates, and the sliders or the pulleys of the arc-shaped sliding plates are embedded in the sliding rails of the arc-shaped rails. A lead screw is longitudinally arranged on the back of the compartment body, and one end of the lead screw is connected with a driving motor. A compartment face sliding groove is formed in the compartment face of the compartment body, a hauling hook is arranged in the compartment face sliding groove, and a hook holder of the hauling hook is arranged on the lead screw. The stretcher compartment has a simple structure and moves flexibly and reliably. The stretcher compartment can be tilted in the vertical direction so as to adapt to the height of a stretcher getting on a bus, and the stretcher can also be mechanically dragged into the compartment. The physical operation of medical workers is replaced, and the labor intensity of the medical workers is lowered.

[0016] The present invention will be further described in detail below in conjunction with the drawings.

[0017] figure 1 It is a three-dimensional schematic diagram of the stretcher warehouse of the present invention. Both ends of the two arc-shaped rails 1 are fixed on the fixed plate 7 and kept parallel to each other. The outer sides of the two arc-shaped rails are provided with arc-shaped slideways 101. Such as figure 1 , 3 As shown, the two sides of the back of the warehouse body are provided with arc-shaped sliding plates 2 respectively, and four sliding blocks or pulleys 201 are arranged on the inner side of the arc-shaped sliding board, and the sliding blocks or pulleys of the arc-shaped sliding board are nested in the slideway of the arc-shaped track. Through the sliding of the sliding block or pulley of the arc-shaped sliding board in the slideway of the arc-shaped track, the purpose of tilting and swinging of the warehouse body is achieved.

[0018] Such as image 3 , 5 As shown in 6, the top of the arc of the arc track is provided with a top lock hole 13, and the front part of the arc track is provided with a front lock hole 14; the middle of the back of the arc skateboard is provided with a lock seat 12 near the side. The lock seat is provided with a rotating telescopic lock rod 11, which can be inserted into the top key hole or the front key hole; the rotating telescopic lock rod is covered with a reset torsion spring (inside, not shown), the reset torsion spring makes the rotating telescopic lock The rod remains extended; the outer end of the lock rod is provided with a swing arm, which is connected to the pull rod 10, and the other end of the pull rod is connected to the handle 3 at the front end of the warehouse body.

[0019] Such as figure 2 , 3 As shown, a screw rod 16 is arranged longitudinally on the back of the bin body, the screw rod is positioned on the back of the bin body through two screw rod fixing seats 17, and one end of the screw rod is connected with the driving motor 15. The drive motor 15 is controlled by the control button 6 on the side of the bin body to drive the screw 16 to rotate on the two screw fixing seats 17. figure 1 As shown, the warehouse surface of the warehouse body is provided with a warehouse surface chute 5, a traction hook 4 is arranged in the warehouse surface chute, and the hook seat 4 of the traction hook is assembled on the screw rod. On the back of the silo body, a sliding rod 19 is set. The sliding rod is parallel to the screw rod. The hook seat 4 of the traction hook is provided with a sliding block 18, which is slidably assembled on the sliding rod to ensure the hook of the traction hook. The seat 4 can only move back and forth, and cannot rotate with the screw. The rotation of the screw 16 drives the traction hook 4 to move in the chute 5 of the warehouse surface.

[0020] Before getting on the stretcher, pull the handle at the front end of the warehouse body, pull the rotating telescopic lock rod to rotate through the pull rod, the rotating telescopic lock rod shrinks, exits the top keyhole, and then pulls the warehouse body forward. The warehouse body leans forward. The rotating telescopic lock rod is reversely rotated under the action of the reset torsion spring and inserted into the front lock hole, and the bin body is positioned. The motor drives the screw rod to rotate and drives the traction hook to the front of the bin body. The stretcher moves to the silo body in the inclined state, the traction hook hooks the stretcher, the motor drives the screw rod in reverse, and drives the traction hook to move backward to draw the stretcher to the warehouse body. Pull the handle at the front end of the warehouse body, pull the rotating telescopic lock lever through the pull rod to rotate, the rotating telescopic lock lever shrinks, exits the front keyhole, and then pushes the warehouse body backwards. After the warehouse body is in place, rotate the telescopic lock lever to reset the torsion spring Reverse rotation under the action of, and insert into the top lock hole, the bin body is positioned, and the stretcher gets on the car.
