[0018] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-5 As shown, a detachable stretcher for air transport of medical personnel includes a first frame 1, a second frame 2 rotatably connected to one side of the first frame 1, and the first frame 1 and the second frame 2 are rotatably connected by a pin. An adjustment box 6 is rotatably connected to the bottom of the first frame 1, and a connecting rod 8 is rotatably connected to the bottom of the first frame 1. A slider 9 is hinged to the end of the connecting rod 8 near the second frame 2. A threaded rod 10 is fixedly connected inside the adjustment box 6, and the slider 9 is threaded onto the threaded rod 10. A knob 11 is fixedly connected to the end of the threaded rod 10 away from the second frame 2. The knob 11 is fixedly connected to the side near the adjustment box 6. A number of limiting posts 12 are fixedly connected to the adjustment box 6 on the side away from the second plate frame 2. A rotating shaft 13 is fixedly connected to the side of the knob 11 near the first plate frame 1. The rotating shaft 13 is rotatably connected to the adjustment box 6. A number of protruding strips are fixedly connected to the rotating shaft 13. The rotating shaft 13 is locked to one end of the threaded rod 10. To ensure power transmission, a number of protruding strips (or drive keys) are fixedly connected to the end of the rotating shaft 13 located inside the adjustment box 6. The corresponding end of the threaded rod 10 is provided with a keyway that matches it. Through the locking of the protruding strips and the keyway, the synchronous rotation between the rotating shaft 13 and the threaded rod 10 is realized. This design allows the rotation of knob 11 to be effectively transmitted to threaded rod 10. Knob 11 is pulled away from the side away from the second frame 2, and then knob 11 is rotated. The rotation of knob 11 drives threaded rod 10 to rotate, and the rotation of threaded rod 10 drives slider 9 to slide on threaded rod 10. Sliding slider 9 pushes up one side of the first frame 1 through connecting rod 8. By rotating knob 11 in the forward or reverse direction, the angle between the first frame 1 and the second frame 2 can be adjusted, thereby adjusting the backrest angle of the patient to adapt to patients in different situations.

[0019] The first pull rod 3 is fixedly connected to both the front and rear sides of the first plate frame 1 and the second plate frame 2.

[0020] The first plate frame 1 and the second plate frame 2 are both fixedly connected to the second tie rod 4 on the side away from the first tie rod 3.

[0021] The top of the first frame 1 and the second frame 2 are both fixedly connected with pads 5, and the top of the first frame 1 and the second frame 2 are both fixedly connected with straps 17. The patient's head is placed on the first frame 1 and the legs are placed on the second frame 2. Then the straps 17 are tightened to fix the patient on the device.

[0022] The bottom of the second plate frame 2 is fixedly connected to the bottom box 7, and several locking blocks 15 are fixedly connected to the side of the bottom box 7 near the adjustment box 6.

[0023] The regulating box 6 has several slots 14 on the side near the bottom box 7, and the locking block 15 is engaged in the slots 14.

[0024] The bottom of both the adjustment box 6 and the base box 7 are fixedly connected with several support feet 16. By pulling out the pin between the first plate frame 1 and the second plate frame 2 and disengaging the locking block 15 from the locking slot 14, the first plate frame 1 and the second plate frame 2 can be separated, so that the device will not occupy too much space when it is not in use.

[0025] Working principle: When using the device, the operator first places the patient's head on the first plate 1 and the legs on the second plate 2, and then tightens the straps 17 to fix the patient to the device.

[0026] Pull the knob 11 away from the side away from the second frame 2, and then rotate the knob 11. The rotation of the knob 11 drives the threaded rod 10 to rotate, and the rotation of the threaded rod 10 drives the slider 9 to slide on the threaded rod 10. The slider 9 slides and lifts one side of the first frame 1 through the connecting rod 8. By rotating the knob 11 in the forward or reverse direction, the angle between the first frame 1 and the second frame 2 can be adjusted, thereby adjusting the backrest angle of the patient to adapt to patients in different situations.

[0027] By pulling out the pin between the first plate frame 1 and the second plate frame 2 and disengaging the locking block 15 from the locking slot 14, the first plate frame 1 and the second plate frame 2 can be separated, so that the device will not occupy too much space when idle.
