[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1, please refer to Figures 1-5 A stretcher strap includes a tightening structure 1, which includes a protective sleeve 101. Both ends of the protective sleeve 101 are equipped with transmission structures, each connected to a rotating shaft 104. One end of the rotating shaft 104 extends into the protective sleeve 101, and two rollers 105 are fixedly fitted onto the outer surface of the rotating shaft 104. Strap assemblies 2 are wound onto each of the two rollers 105, and the strap assemblies 2 are positioned on opposite sides of the protective sleeve 101. Rotating the transmission structure drives the rotating shaft 104 and the rollers 105 to rotate, and the rollers 105 wind up the strap assemblies 2 to tighten them. Compared to traditional strapping methods, medical personnel can more quickly secure the injured person. Because of the winding method, the strap assemblies 2 do not have excess material exposed and drag on the ground, eliminating the potential risk of medical personnel slipping and falling, reducing the probability of secondary accidents, and ensuring the safety of emergency medical work.

[0028] Furthermore, the strap assembly 2 includes a strap body 203 with one end fixedly connected to the roll 105. The other end of the strap body 203 extends out of the protective sleeve 101 and extends to the outside of the protective sleeve 101 and is fixedly connected to a connecting ring 201. A spring buckle 202 is connected to the connecting ring 201. The spring buckle 202 is used to fasten to the stretcher. The method of connecting the stretcher with the spring buckle 202 is not only convenient and quick, but also has strong stability after connection and is not easy to fall off.

[0029] Furthermore, a protective shell 102 is connected to the end of the protective sleeve 101, the outer surface of the rotating shaft 104 passes through the protective shell 102, and a bearing is provided at the connection between the rotating shaft 104 and the protective shell 102.

[0030] Furthermore, the transmission structure includes a worm gear 107 rotatably connected to the protective shell 102 via a bearing. The worm gear 107 is connected to a worm wheel 106 located inside the protective shell 102. The worm wheel 106 is fixedly sleeved on the outer surface of the rotating shaft 104. When the worm gear 107 rotates, it can drive the rotating shaft 104 to rotate through the worm wheel 106, and then drive the drum 105 to rotate through the rotating shaft 104 to wind up or release the strap body 203. The worm wheel 106 and the worm gear 107 adopt a self-locking design so that the strap body 203 can maintain its fixed state on the injured person after being wound up.

[0031] Furthermore, one end of the worm gear 107 extends to the outside of the protective housing 102 and is fixedly connected to a handwheel 108, which facilitates manual rotation of the worm gear 107.

[0032] Furthermore, a protective plate 103 is provided on the side of the protective shell 102 away from the protective sleeve 101. The protective plate 103 is used to protect the worm gear 106 and the worm 107.

[0033] Furthermore, a base 109 is fixedly installed at the bottom of the protective sleeve 101, and a protective component 110 is provided at the bottom of the base 109. The protective component 110 is used to isolate the base 109 from the upper body of the injured person.

[0034] Furthermore, the protective component 110 is made of flexible rubber, flexible silicone, or an air cushion. Flexible rubber, flexible silicone, or an air cushion are all flexible components that have a good isolation effect.

[0035] Example 2 further optimizes the stretcher straps provided in Example 1. Specifically, the protective component 110 is glued to the bottom of the base 109, resulting in high stability.

[0036] Example 3 further optimizes the stretcher straps provided in Example 1. Specifically, the protective component 110 and the base 109 are detachably connected by Velcro for easy replacement.

[0037] The usage process of the stretcher straps provided by this utility model is as follows:

[0038] Place the protective piece 110 on the patient's chest, then fasten the spring buckle 202 to the stretcher, turn the handwheel 108 to drive the worm gear 107 to rotate, the worm gear 107 drives the rotating shaft 104 to rotate through the worm wheel 106, and then drives the drum 105 to rotate through the rotating shaft 104 to wind up the main body 203 of the strap, so that the strap assembly 2 is tightened to fix the injured person;

[0039] Reverse rotation of handwheel 108 releases the drum 105 from the strap body 203, and then releases spring clip 202 to separate the application from the stretcher and the injured person.
