[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3A multi-terrain protection cart for battlefield wounded, comprising a load-bearing platform 10 and a fixed pillow 20 fixed to one side of the platform, the upper surface of the fixed pillow 20 having a fixed groove 210 for limiting the head, a protective mask 220 is arranged on the upper part of the fixed groove 210, one side of the protective mask 220 is hingedly connected to the fixed pillow, and the other side of the protective mask is locked to the fixed pillow, brackets 110 extend from the four corners of the lower part of the cart, and a rotatable pulley assembly 120 is hingedly connected to the bracket.

[0025] In this embodiment, one side of the protective mask 220 is hingedly connected to the side of the fixed pillow by a hinge, and the other side is locked to the fixed pillow by a snap fit. In actual design, the protective mask 220 on the other side of the hinge connection can also be locked with a butterfly bolt 221 to achieve locking between the protective mask 220 and the fixed pillow 20.

[0026] The protective mask 220 is mainly used when the injured person lies flat on the carrying platform 10 of the cart, with the injured person's head located in the fixed groove 210, and then the protective mask 220 is buckled on to cover the face. After the injured person's head is placed in the fixed groove 210 of the fixed pillow, secondary trauma caused by shaking of the head during transportation of the injured person can be avoided.

[0027] In this embodiment, strip air bags 30 for limiting are fixed on both sides of the carrying platform, and straps 310 are fixed on the strip air bags 30. There are multiple pairs of straps 310 on the strip air bags 30 on both sides of the cart, and the facing ends of each pair of straps have buckles 320 that can be buckled.

[0028] In this embodiment, the carrying platform is extended with a lifting bar 130 for lifting, and the lifting bar 130 extends to both ends of the carrying platform 10 to facilitate holding during transportation.

[0029] The buckle and the strip-shaped airbag 30 can be used to fix the patient on the carrying platform 10 to prevent the injured person from falling.

[0030] In another embodiment of the present invention, the pulley assembly 120 includes a fixed shaft 110 fixedly connected to the lower portion of the bracket 110, a rotating plate 121 is hingedly connected to the fixed shaft, and rotatable pulleys 122 arranged in an equilateral triangle are hingedly connected to the rotating plate.

[0031] like Figure 3 As shown, the utility model adopts a triangular pulley 122 layout, which can better adapt to rugged roads and improve the stability during transportation. Generally, the two pulleys 122 located at the bottom rotate. Each pulley 122 is hingedly connected to the rotating plate 121 via a bearing 123.

[0032] In another embodiment of the utility model, arc-shaped head limiting plates 230 are hingedly connected on both sides of the fixed pillow 20, the lower end of the head limiting plate 230 is protruded from the upper surface of the fixing groove, and a buffer foam pad 240 is fixed to the inner side of the head limiting plate.

[0033] like Figure 4 As shown, in this embodiment, the arc-shaped head stop plate 230 can be used to press down the lower end of the head stop plate 230 after the head of the injured person is placed, so that the upper part of the arc-shaped head stop plate 230 is pushed inward, so that the patient's head is more stable and can adapt to the head contours of different injured people. In addition, the present invention fixes a buffer foam pad 240 on the inner side of the head stop plate to buffer the pressure of the head stop plate on the head.

[0034] The bracket is hingedly connected to the upper part and the trolley, and the bracket and the side of the trolley also have a penetrating locking pin. The locking pin can ensure the vertical setting of the bracket to facilitate transportation in a flat area. The bottom surface of the bearing platform has an air cushion 40, and the lifting bar 130 has an annular recess 131 for tying a rope. A rubber layer 410 is fixed to the bottom of the air cushion 40.

[0035] like Figure 5 As shown, in areas such as mudflats and beaches, the pulley may sink, and thus it is necessary to drag it on the ground through an air cushion, and the tether tied to the annular recess 131 assists in pulling, so as to facilitate sliding on special ground. The bottom of the air cushion 40 is fixed with a rubber layer 410 to improve wear resistance and prevent the air cushion from rupture.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
