[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: a surgical transport bed, including a mobile frame 1;

[0023] Mobile frame 1: Its upper surface is equipped with a lifting unit 2. Casters are located at the four corners of the lower surface of the mobile frame 1 for movement. An upper support plate 3 is located on the upper surface of the lifting unit 2. A guide rod in the middle of the lower surface of the upper support plate 3 is slidably connected to a guide seat on the upper surface of the mobile frame 1. The upper support plate 3 can only move vertically. A bed board 4 is slidably connected to the upper surface of the upper support plate 3. A support shaft 5 is located in the middle of the upper surface of the upper support plate 3. A lever 6 is rotatably connected to the outside of the support shaft 5. A sliding column 7 is located in the middle of the lower surface of the bed board 4. The sliding column 7 is slidably connected to the long sliding hole at the rear end of the lever 6. A handle 8 is rotatably connected to the front end of lever 6. Lifting handle 8 upwards aligns it with lever 6, and then longitudinally moving handle 8 causes lever 6 to rotate around support shaft 5. The long sliding hole at the rear end of lever 6 slides relative to sliding post 7. The upper support plate 3 has evenly distributed sliders 9 in the middle of its upper surface, and the lower surface of the bed board 4 has evenly distributed slide rails 10. The sliders 9 are all slidably connected to the vertically corresponding slide rails 10. Sliding post 7 drives the bed board 4 and slide rails 10 to slide longitudinally along the sliders 9, thereby controlling the bed board 4's movement relative to the external bed frame. The upper support plate 3 has a body overlap, and both ends of its upper surface are rotatably connected to evenly distributed rollers 16. The rollers 16 are slidably connected to the lower surface of the bed board 4, providing sliding support. Both ends of the lower surface of the bed board 4 are provided with positioning blocks 15, which cooperate with longitudinally adjacent sliders 9. The bed board 4 moves synchronously with the positioning blocks 15, and the positioning blocks 15 contact the sliders 9 to limit the movement range of the bed board 4. Guardrails 11 are slidably connected to both ends of the upper support plate 3, and positioning frames are slidably connected to both sides of the upper support plate 3. 12. The end of the positioning frame 12 near the center of the upper support plate 3 is movably engaged with the longitudinally adjacent guardrail 11. The end of the positioning frame 12 away from the guardrail 11 is movably sleeved with a spring 13. The left and right sides of the upper support plate 3 are provided with positioning pieces 14. The two springs 13 are located between the crossbar of the positioning frame 12 and the longitudinally adjacent positioning pieces 14. When the guardrail 11 is pulled upward, after the guardrail 11 moves upward, its slot corresponds with the positioning frame 12. Under the action of the positioning pieces 14, the springs 13 push the positioning frame 12 to movably engage with the guardrail 11, thereby restricting the downward movement of the guardrail 11.

[0024] The lifting unit 2 includes a lower support arm 21, a connecting shaft 22, an upper support arm 23, a double-acting screw 24, and a nut 26. There are four lower support arms 21, which are respectively located on the front and rear sides of the left and right ends of the movable frame 1, and are rotatably connected by a lower rotating shaft. The upper ends of each of the four lower support arms 21 are rotatably connected to an upper support arm 23 via a connecting shaft 22. The upper ends of each of the four upper support arms 23 are rotatably connected to an upper support plate 3 via an upper rotating shaft. Nuts 26 are provided between two horizontally corresponding connecting shafts 22, and a double-acting screw 24 is threaded between the two nuts 26. Rotating the handwheel at the end of the double-acting screw 24 rotates the double-acting screw 24. The rotation causes the two nuts 26 to move closer or further apart, and the nuts 26 drive the connecting shaft 22 to move synchronously. The lower support arm 21 and the upper support arm 23 form a horizontal V-shaped structure through the connecting shaft 22. The V-shaped structures at the front and rear ends are set opposite each other, and the positions of the upper and lower support points remain unchanged. When the connecting shaft 22 moves, it will drive the angle between the lower support arm 21 and the upper support arm 23 to change, thereby adjusting the height of the upper support plate 3. The lifting unit 2 also includes a tension spring 25, which is set between the two nuts 26. The tension spring 25 is movably connected to the bidirectional screw 24. The tension spring 25 provides tension to the two nuts 26, reducing the force of the bidirectional screw 24 driving the upper support plate 3 to move upward.

[0025] The working principle of the surgical transport bed provided by this utility model is as follows: When transporting a patient, the moving frame 1 is moved. The four corners of the lower surface of the moving frame 1 are equipped with casters for movement. After the upper support plate 3 is aligned parallel to the operating table or hospital bed, the positioning frame 12 near the outer bed body is pulled. The positioning frame 12 moves to compress the spring 13 and separates from the slot of the guardrail 11. Then the guardrail 11 can move downwards, and the upper surface of the guardrail 11 is flush with the upper surface of the upper support plate 3. After moving closer, the handwheel at the end of the double-acting screw 24 is rotated. The rotation of the double-acting screw 24 drives the two nuts 26 to move closer or further apart. The nuts 26 drive the connecting shaft 22 to move synchronously. The lower support arm 21 and the upper support arm 23 form a horizontal V-shaped structure through the connecting shaft 22. The V-shaped structures at the front and rear ends are set opposite each other, and the positions of the upper and lower support points remain unchanged. When the connecting shaft 22 moves, it will drive the included angle between the lower support arm 21 and the upper support arm 23 to change, thereby adjusting the height of the upper support plate 3. The support plate 3 is level with the height of the hospital bed. Then, the handle 8 is lifted upwards, forming a straight line with the lever 6. The handle 8 is then pulled longitudinally, causing the lever 6 to rotate around the support shaft 5. The long sliding hole at the rear end of the lever 6 slides relative to the sliding column 7, and the sliding column 7 drives the bed board 4 and the slide rail 10 to slide longitudinally along the slider 9. This allows the bed board 4 to be connected to the external bed frame. After connection, the patient is moved to the middle of the bed board 4. After the patient is moved, the bed board 4 is controlled to move back to its original position. Then, the guardrail 11 is pulled upwards. After the guardrail 11 moves upwards, its slot aligns with the positioning frame 12. The spring 13, under the action of the positioning piece 14, pushes the positioning frame 12 to engage with the guardrail 11, thus restricting the downward movement of the guardrail 11. Then, the upper support plate 3 can be pushed to move to transfer the patient. After the transfer is completed, the guardrail 11 is lowered to connect the bed board 4 to the external bed frame for easy patient movement.
