The two universal joint seats 32 are respectively connected to the two support rods 2 in the same group in a universal rotation manner. The two ends of the keel body 31 are respectively connected to the two universal joint seats 32 in the same group, and are detachably connected to at least one universal joint seat 32.

[0039] In this embodiment, please refer to Figure 5 , the keel body 31 is detachably connected to at least one universal shaft seat 32, and the two universal shaft seats 32 are universally connected to the support rods 2, so that one end of the keel body 31 can be detached from the universal shaft seat 32 when transporting or storing the stretcher. At this time, the other end of the keel body 31 can droop under the drive of its own weight, so that the two support rods 2 in the same group can be close to each other, further reducing the volume of the stretcher. It should be noted that in one embodiment, an anti-slip rubber is provided in the middle of the keel body 31, which can be used as a handle 7 in the cart form. The two ends can be disassembled by applying force along the axial direction of the keel body 31, thereby compressing the width of the stretcher for easy storage or transportation. In another embodiment, the keel body 31 and the universal shaft seat 32 can be detachably connected in the form of pins and pin control, or in other forms, which will not be elaborated here.

[0040] In one embodiment, the flexible stretcher surface 5 is provided with two groups of shoulder straps 53 at both ends of the support rod 2 in the axial direction, the two groups of shoulder straps 53 are respectively connected to the two groups of keels 3, and the flexible stretcher surface 5 is provided with a safety belt 54 on the side close to the blocking side 11.

The stretcher has two sets of safety belts 54, which are composed of nylon belts and E-shaped buckles, which can fix the upper and lower body of the patient respectively.

[0042] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the present invention is described in detail: In this embodiment, the frame of the stretcher is connected by four support rods 2 and two arc-shaped connecting arc plates 13 through a connecting shaft. The cross section of the connecting arc plate 13 in the radial direction is semi-cylindrical, which is just adapted to the shape of the support rod 2. The arc opening faces upward. If pressure is applied from top to bottom, the stretcher can be made into a horizontal plane for transporting patients; if the stretcher is turned over, the support rod 2 can be easily rotated 90° around the connecting shaft, so that the stretcher becomes a cart form, and the end facing the ground is connected to the universal wheel 41 for convenient transportation, and the other end is connected to the handle 7. The handle 7 has anti-skid grooves to increase friction. The width of the stretcher is fixed by the keel 3 at both ends of the stretcher frame. It is connected to the support rod 2 in the form of a universal shaft, and anti-skid rubber is provided in the middle, which can be used as a handle 7 in the cart form. The two ends can be disassembled by applying force along the direction of the rod, thereby compressing the width of the stretcher for easy storage.

[0043] It also has the following advantages: increasing the use scenarios of rescue stretchers and reducing the idle time of stretchers; increasing the contact opportunities between rescue stretchers and ordinary people, thereby improving their response capabilities and self-protection awareness in emergency situations; it can be used as a tool for transporting rescue supplies in the early stage of rescue, thereby improving rescue efficiency; modular design, components can be replaced individually, which is in line with the concept of sustainable development.

[0044] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
