[0014] Preferably, a fixing strap installation opening is fixedly connected to the upper surface of the life-saving stretcher body, and the outer wall of the second fixing seat can conflict with the outer wall of the second cross bar.

[0015] Working principle: when in use, the pulling block is pulled to cause the pulling block to drive the first sliding column to slide inside the fixed cylinder. When the first sliding column slides in the fixed cylinder, it will drive the sliding block to slide on the inner wall of the fixed cylinder and pull the cross block to slide out from the inner wall of the cross slot. In this process, the first spring slidably connected to the outer wall of the first sliding column will be forced to shrink and slide on the outer wall of the first sliding column. At this time, the first cross bar and the support rod drive the first cross bar to rotate ninety degrees, so that the first cross bar drives the rotating column to rotate inside the first fixed seat. When the second cross bar and the support rod are adjusted to be parallel to the life-saving stretcher body, the pulling block is no longer pulled at this time, so that the first spring in the contracted state is reset, and then the sliding block is reset and slides on the inner wall of the fixed cylinder, so that The cross block is reset and slides into the inner wall of the cross slot opened at one end of the rotating column. At this time, the first cross bar will no longer rotate. At this time, the support rod and the second cross bar are parallel to the life-saving stretcher body. This situation is suitable for use in water. Since the outer wall of the support rod is fixedly connected with the second side floating air bag, the outer wall of the second cross bar is fixedly connected with the first side floating air bag, when used in water, the contact area with the water surface is increased, the shaking amplitude of the stretcher in the water is reduced, the stability of the stretcher is improved, and the risk of rollover is reduced. When the second cross bar is adjusted to the lower side of the life-saving stretcher body and perpendicular to the horizontal plane of the life-saving stretcher body, it is suitable for use on flat land. When the second cross bar is adjusted to the lower side of the life-saving stretcher body, the second cross bar The moving wheels arranged inside the stretcher will directly contact the ground, and then the life-saving stretcher body can be moved by directly pushing the stretcher body. When the second cross bar is adjusted to the upper side of the stretcher body and is perpendicular to the horizontal plane of the stretcher body, it is suitable for rugged land terrain. The user can lift the stretcher body by the handle to adapt to rugged terrain conditions. When the first side floating airbag is adjusted to the upper side of the stretcher body, the support rod and the second cross bar will also be located on the upper side of the stretcher body, so that the second side floating airbag fixedly connected to the outer wall of the support rod and the first side floating airbag fixedly connected to the outer wall of the second cross bar can provide additional protection for the injured. After use, the second L-shaped block is pressed to cause the second L-shaped block to slide on the first The outer wall of the L-shaped block drives the clamping column to slide out from the inner wall of the clamping hole. During this process, the second sliding column fixedly connected to the outer wall of the second L-shaped block will also slide on the inner wall of the limiting groove, and the second spring will be forced to shrink and slide on the inner wall of the circular groove. When the clamping column completely slides out from the inner wall of the clamping hole opened in the outer wall of the third L-shaped block, the second cross bar can be moved horizontally to cause the support rod to rotate simultaneously on the outer walls of the third fixed seat and the second fixed seat to fold the second cross bar and the support rod. When the outer wall of the second fixed seat and the outer wall of the second cross bar collide with each other, the folding of the second cross bar and the support rod is completed, which is conducive to saving space, facilitating carrying and transportation, and improving mobility. It can also be quickly deployed and used according to different rescue scenarios, thereby improving flexibility of use.

[0016] The present invention provides a multifunctional amphibious life-saving stretcher. It has the following beneficial effects:

[0017] 1. In the present invention, by pulling the pulling block, the fixed tube drives the sliding block to slide on the inner wall of the fixed tube and pulls the cross block to slide out from the inner wall of the cross slot, and then the first cross bar is driven to rotate 90 degrees by the second cross bar and the support rod as needed, the life-saving stretcher can be quickly and conveniently adjusted to a use state suitable for use in water, flat land or rugged land terrain as needed, and the use state can be quickly and conveniently adjusted according to different environments, thereby improving the rescue efficiency, and the rescue personnel can quickly engage in rescue operations to gain precious treatment time for the injured.

[0018] 2. In the present invention, by adjusting the support rod and the second cross bar to be parallel to the life-saving stretcher body, due to the second side floating airbag fixedly connected to the outer wall of the support rod and the first side floating airbag fixedly connected to the outer wall of the second cross bar, when used in water, the contact area with the water surface is increased, the shaking amplitude of the stretcher in the water is reduced, the stability of the stretcher is improved, and the risk of rollover is reduced.

[0019] 3. In the present invention, the second L-shaped block is pressed to cause the clamping column to slide out from the inner wall of the clamping hole, and then the second cross bar can be moved horizontally to cause the support rod to rotate simultaneously on the outer walls of the third fixed seat and the second fixed seat to fold the second cross bar and the support rod, which is beneficial to saving space, facilitating carrying and transportation, improving maneuverability, and can also be quickly unfolded and used according to different rescue scenarios, thereby improving flexibility of use.

[0030] Specifically, the life-saving stretcher body 1 is used to carry patients, and the bottom floating airbag 2 is used to provide a certain buoyancy to the life-saving stretcher body 1 when the life-saving stretcher body 1 is in water, thereby allowing the life-saving stretcher body 1 to be used in water. At the same time, it can provide a certain buffering effect to the life-saving stretcher body 1 when used on land, and can play a certain buffering role for the injured when impacted. The first fixing seat 3 can be used to fix the first fixing seat 3. The rotating column 4 can be rotated inside the first fixing seat 3 through the first fixing seat 3, so that the first cross bar 5 drives the support rod 7 and the second cross bar 9 to rotate to adjust the position according to actual usage. When the support rod 7 and the second cross bar 9 are adjusted to be horizontally parallel to the life-saving stretcher body 1, it is suitable for use in water. The support rod 7 and the second cross bar 9 extend a distance, and the outer wall of the support rod 7 The second side floating airbag 12 fixedly connected to the outer wall of the second cross bar 9 can effectively increase the contact area with the water surface, reduce the shaking amplitude of the stretcher in the water, improve the stability of the stretcher, and reduce the risk of rollover. When the second cross bar 9 is adjusted to the lower side of the life-saving stretcher main body 1, the moving wheels 10 arranged inside the first side floating airbag 11 will directly contact the ground, so that the life-saving stretcher main body 1 can be easily moved. When the second cross bar 9 is adjusted to the upper side of the life-saving stretcher main body 1, it is suitable for terrain that cannot be passed by the moving wheels 10.

When the pull block 20 is no longer pulled, the first spring 21 in the contracted state will rebound and drive the cross block 18 to reset through the sliding block 17 and slide into the inner wall of the cross slot 14 opened at one end of the rotating column 4. The cross design of the cross block 18 and the cross slot 14 can ensure that the rotating column 4 always maintains a ninety-degree rotation.

[0033] Reference Figure 3 and Figure 4 One end of the first spring 21 is fixedly connected to one end of the sliding block 17 close to the first sliding column 19, and the other end of the first spring 21 is fixedly connected to the inner wall of the fixed cylinder 16; the outer wall of the second cross bar 9 is fixedly connected to the first L-shaped block 22, and the outer wall of the first L-shaped block 22 is provided with a limiting groove 23; the outer wall of the first L-shaped block 22 is slidably connected to the second L-shaped block 24, and the outer wall of the second L-shaped block 24 is fixedly connected to the second sliding column 25, and the outer wall of the second sliding column 25 is slidably connected to the inner wall of the limiting groove 23;

[0034] Specifically, one end of the first spring 21 is fixedly connected to one end of the sliding block 17 close to the first sliding column 19, and the other end of the first spring 21 is fixedly connected to the inner wall of the fixed cylinder 16, which can prevent the sliding block 17 from rotating when sliding on the inner wall of the fixed cylinder 16, thereby preventing the cross block 18 from rotating. The second cross bar 9 can fix the first L-shaped block 22, and the second sliding column 25 can slide on the inner wall of the limiting groove 23 opened on the outer wall of the first L-shaped block 22 to limit the second L-shaped block 24, thereby ensuring that the second L-shaped block 24 moves in the horizontal direction when moving.

[0035] Reference Figure 4 - Figure 6 , a circular groove 26 is formed on the outer wall of the second L-shaped block 24, and a clamping column 28 is fixedly connected to the outer wall of the second L-shaped block 24; referring to the figure, one end of a second spring 27 is fixedly connected to the inside of the second L-shaped block 24, and the other end of the second spring 27 is fixedly connected to the outer wall of the second cross bar 9, and the outer wall of the second spring 27 is slidably connected to the inner wall of the circular groove 26; referring to the figure, a third L-shaped block 29 is fixedly connected to the outer wall of the support rod 7, and a clamping hole 30 is formed on the outer wall of the third L-shaped block 29;

[0036] Specifically, the second L-shaped block 24 can be used to fix the clamping column 28. When the second spring 27 is subjected to force, the second spring 27 will shrink and slide on the inner wall of the circular groove 26. One end of the second spring 27 is fixedly connected to the inside of the second L-shaped block 24, and the other end is fixedly connected to the outer wall of the second cross bar 9, so as to connect the second L-shaped block 24 and the second cross bar 9. The third L-shaped block 29 can be fixed by the support rod 7, so as to ensure that the third L-shaped block 29 remains fixed in a fixed position.

[0037] Reference Figure 4 - Figure 6 The outer wall of the clamping column 28 is slidably connected to the outer wall of the third L-shaped block 29, and the outer wall of the clamping column 28 is slidably connected to the inner wall of the clamping hole 30; the upper surface of the life-saving stretcher body 1 is fixedly connected with a fixed belt installation port 31, and the outer wall of the second fixing seat 6 can conflict with the outer wall of the second cross bar 9;

[0038] Specifically, in the process of extending the second cross bar 9 in the folded state, the second cross bar 9 will drive the second L-shaped block 24 to move, thereby making the clamping column 28 slide on the outer wall of the third L-shaped block 29. When the outer wall of the clamping column 28 slides to the inner wall of the clamping hole 30, the extension of the second cross bar 9 is completed. At this time, the clamping column 28 is in contact with the inner wall of the clamping hole 30, which can ensure that the support rod 7 and the second cross bar 9 remain in a vertical state, and also ensure that the support rod 7 and the second cross bar 9 remain in a vertical state without shaking. The fixing strap installation port 31 is used to tie the strap to fix the injured person to prevent the patient from tipping over and falling off during the movement. When the second cross bar 9 is in the folded state, the outer wall of the second fixing seat 6 conflicts with the outer wall of the second cross bar 9.
