The gasket winding component 11 is fixedly connected to the left end of the top wall of the front fixing plate 10;

[0030] The middle-end fixing part 2, the middle-end fixing part 2 includes two groups of strip-shaped fixing plates 20, a movable plate 21, a support plate 22, a left locking bolt 23 and a plurality of right fixing bolts 24. The left end of the strip-shaped fixing plate 20 is semicircular, and the right end is rectangular. A longitudinal through hole 200 is provided in the middle position of both ends. The support plate 22 and the strip-shaped fixing plate 20 are integrally formed, and an arc-shaped sliding groove 202 is provided on the side wall of the connection part facing each other, and a strip-shaped groove 201 is provided on the side wall far away from each other. A moving component 25 is movably connected in the strip-shaped groove 201. The front and rear side walls of the right end of the movable plate 21 are elastically hinged to two groups of strip-shaped fixing plates 20 respectively. Sliding columns 210 are provided on the front and rear side walls of the left end, and the sliding columns 210 are slidably connected in the arc-shaped sliding groove 202. The semicircular connecting ear 100 is rotatably connected in the longitudinal through hole 200 at the left end of the strip-shaped fixing plate 20. The left locking bolt 23 penetrates through the strip-shaped fixing plate 20 and contacts the semicircular connecting ear 100, and the left locking bolt 23 is threadedly connected to the strip-shaped fixing plate 20. The right fixing bolt 24 penetrates through the front and rear side walls of the longitudinal through hole 200 and is threadedly connected thereto;

[0031] The rear-end fixing part 3, the rear-end fixing part 3 includes a combined frame 30 and a gasket limiting component 31. The left end of the combined frame 30 is rotatably connected to the side wall of the longitudinal through hole 200 at the right end of the strip-shaped fixing plate 20. The gasket limiting component 31 is fixedly connected to the combined frame 30.

[0032] Before specific use, the equipment can be adjusted according to the needs of the patient and the actual conditions of the terrain environment. It is divided into three forms, one is the backpack type, the second is the towing type, and the third is the lifting type. If the backpack type is adopted, the front fixing part 1 and the rear fixing part 2 need to be adjusted respectively through the left locking bolt 23 and the right fixing bolt 24, so that the three are stepped, and the angles of the front fixing part 1 and the middle fixing part 2 can be appropriately adjusted to keep the patient in a comfortable posture. At this time, the arc handle 12 can serve as a shoulder strap for carrying to facilitate the transportation of the equipment. It is worth noting that the moving component 25 in this state can be adjusted to the bar groove 2 01, and rest during the carrying process is convenient for resting by using the lower end of the support plate 22; and if there is only one rescuer who needs to be towed, first of all, the front fixing part 1, the middle fixing part 2 and the rear fixing part 3 need to be adjusted to an arc-like state, so that the rescuer can tow it in an upright state, and at the same time, the moving component 25 on the middle fixing part 2 is adjusted to the lowest end of the strip groove 201, so that the rolling wheel 255 is under the support plate 22 to assist in movement. If the lifting type is adopted, the equipment can be adjusted to a straight line shape to facilitate the lifting of two rescuers. The adjustment method is as follows: by loosening the left lock The locking bolt 23 is tightened so that it is out of contact with the semicircular connecting ear 100, so that the front fixing part 1 can be freely rotated and adjusted, and the front fixing part 1 can be locked again after the adjustment is appropriate. It is worth noting that in order to enhance the friction, the contact part between the left locking bolt 23 and the semicircular connecting ear 100 can be a combination of convex points and concave holes or a tooth groove. The adjustment of the middle fixing part 2 and the rear fixing part 3 is fixed by the longitudinal through hole 200 at the right end of the strip fixing plate 20 and the right fixing bolt 24. Taking the middle fixing part 2 and the rear fixing part 3 as an example of a straight line, when the backpack type is adopted, only Remove the right fixing bolt 24 located under the front side wall of the strip fixing plate 20, rotate the rear end fixing part 3, and then install it again to lock it. It is worth noting that the transfer equipment can be adjusted to a "U" shape, which is convenient for rescue personnel to carry the entire transfer equipment on their backs and move it to search for patients in the wild. In addition, in order to ensure the protection of patients during the rescue process, the pad 113 can be replaced with a pad with a protective fixing belt type according to actual needs, or a plurality of protective belts similar to seat belts can be installed on the front and rear side walls of the transfer equipment. This type of protective belt is relatively mature in the existing technology, so it will not be repeated here.

[0033] Specifically, the gasket winding assembly 11 includes a semi-circular housing 110, a rotating shaft 111, two sets of scroll springs 112, and a gasket 113. The semi-circular housing 110 is fixedly connected to the left end of the front end fixing plate 10. The rotating shaft 111 passes through the scroll springs 112 and is rotatably connected to the front and rear side walls of the semi-circular housing 110. The two sets of scroll springs 112 are located at both ends of the rotating shaft 111 and are respectively fixedly connected to the rotating shaft 111 and the concave side wall of the semi-circular housing 110. One end of the gasket 113 is fixedly connected to the middle position of the rotating shaft 111, and the other end is provided with a plurality of hanging rings 1130 fixedly connected thereto. Through the arrangement of the rotating shaft 111 and the scroll springs 112 provided in the semi-circular housing 110, the gasket 113 fixedly connected to the rotating shaft 111 can be used according to the actual situation. When the gasket 113 is pulled out and fixed through the hanging ring 1130, during the process of gradually lowering the patient from the feet, under the action of the patient's weight, an appropriate length of the gasket 113 is pulled out to make it fit closely with the patient, avoiding the situation that the gasket 113 is too loose and gets caught on branches or other protrusions during transportation, forming resistance and causing secondary injury to the patient.

[0034] Specifically, the combination frame 30 includes two sets of outer plates 300, a U-shaped plate 301, a pedal 302, a plurality of universal wheels 303, and two sets of springs 304.

The pedal 302 is fixedly connected to the right end of the top wall of the U-shaped plate 301, and the universal wheel 303 is fixedly connected to the right end of the bottom wall of the U-shaped plate 301. The combination frame 30 is arranged with the U-shaped plate 301 sleeved inside the outer plate 300, so that the patient's foot rests on the pedal 302, and the U-shaped plate 301 is pushed out to different use lengths according to the different lengths of the lower limbs to match, thereby achieving the purpose of changing the overall length of the transportation equipment according to the actual situation, avoiding the situation that the stretcher length is too long and affects transportation during field transportation. When using the backpack type, the patient's foot can step on the pedal 302, and with the assistance of the externally connected fixing belt, the patient's lower limb is fixed.

[0035] Specifically, the right fixing bolts 24 are located at the upper and lower ends of the front side wall of the strip-shaped fixing plate 20, and the distance between the two right fixing bolts 24 is greater than the height of the outer plate 300, and the lateral distance from the right fixing bolt 24 to the left side wall of the longitudinal through hole 200 is greater than the height of the outer plate 300; the setting that the distance between the right fixing bolts 24 and the distance between the right fixing bolts 24 and the side wall of the longitudinal through hole 200 are greater than the height of the outer plate 300 can ensure that the outer plate 300 can be fixed regardless of whether it is in the vertically upward, vertically downward or horizontal state.

[0036] Specifically, the gasket limiting assembly 31 includes a limiting plate 310 and a plurality of limiting columns 311. The two ends of the limiting plate 310 are fixedly connected to the two outer plates 300 respectively. The limiting columns 311 are fixedly connected to the bottom wall of the limiting plate 310, and the number and position of the limiting plates 310 match the hanging rings 1130; the gasket 113 is stretched and fixed through the arrangement of the limiting plate 310 and the limiting columns 311.

[0037] Specifically, fixing holes 2010 are provided on the left and right side walls at the upper and lower ends of the strip-shaped groove 201.

[0038] Specifically, the moving assembly 25 includes a fixed block 250, a turning handle 251, a cam 252, a plurality of return springs 253, a fixed strip 254, a roller frame 255 and a rolling wheel 256. A rectangular through cavity 2500 is provided inside the rear end of the fixed block 250. The cam 252 is located in the middle of the rectangular through cavity 2500. The turning handle 251 penetrates the fixed block 250 and is fixedly connected to the cam 252, and the turning handle 251 is threadedly connected to the fixed block 250. There are two groups of fixed strips 254, which are respectively located on the left and right sides of the cam 252, and their positions match the positions of the fixing holes 2010. One end of the return spring 253 is fixedly connected to the side wall of the fixed strip 254, and the other end is fixedly connected to the cavity wall of the through cavity 2500. The roller frame 255 is fixedly connected to the bottom wall of the front end of the fixed block 250. The rolling wheel 256 is rotatably connected to the roller frame 255; when different transportation methods are adopted, the position of the moving assembly 25 can be adjusted to achieve different purposes. During adjustment, first rotate the turning handle 251 to drive the rotation of the cam 252 in the rectangular through cavity 2500, so that the cam 252 is separated from the fixed strip 254. In this case, the fixed strip 254 retracts into the rectangular through cavity 2500 under the action of the return spring 253, and the moving assembly 25 can slide freely in the strip-shaped groove 201. After sliding to the upper or lower end, rotate the turning handle 251 again to drive the rotation of the cam 252, so that the cam 252 contacts the fixed strip 254 and extrudes the end of the fixed strip 254 away from the cam 252 out of the rectangular through cavity 2500 and locks it in the corresponding fixing hole 2010 to form a fixation for the moving assembly 25.

[0039] The present invention has been further described above in connection with the embodiments. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
