[0002] A stretcher is a piece of equipment used to transport patients. It is a common piece of equipment in medical institutions, used by doctors and nurses to move patients. Furthermore, stretchers are frequently used in other emergencies such as fires, earthquakes, and natural disasters. They can also be used to transport other items, such as packages and boxes. Because of their widespread use in medical institutions, stretchers can be considered a type of medical equipment. In national standards, stretchers are classified as medical instruments and equipment. In addition, stretchers can be categorized into different types based on their usage and functional requirements. For example, according to their materials and structure, stretchers can be divided into aluminum alloy stretchers, steel stretchers, and plastic stretchers.

[0003] Stretchers are essential items for ambulances in emergency rescue and disaster relief operations. They are often transported by vehicle to quickly reach the rescue site. However, existing stretchers are not easy to fold and unfold, require a lot of space during transportation, reduce the amount of goods that can be transported at one time, and squeeze the space of other equipment. Moreover, once they arrive at the rescue site, they cannot be quickly unfolded and used, which is inconvenient for rescuers to operate, reduces rescue efficiency, and threatens the life safety of the rescued. Therefore, it is necessary to propose a stretcher that is easy to unfold to solve the above problems. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes a stretcher that is easy to unfold, capable of quick folding and unfolding, which facilitates vehicle transportation and operation by rescue personnel, thereby increasing the survival rate of those being rescued.

[0005] To achieve the above objectives, the present invention proposes the following specific solutions:

[0006] A stretcher that is easy to unfold includes a connecting plate. The connecting plate has symmetrical first rotating holes on its sidewalls, which penetrate the connecting plate. A stretcher cloth is symmetrically arranged above the connecting plate. Folding plates are symmetrically fixed to the sidewalls of the stretcher cloth. A fixing block is fixed to the bottom edge of the folding plate. A first rotating shaft is fixed to the sidewall of the fixing block, which penetrates the first rotating hole. A second support plate is fixed to the other side of the bottom surface of the folding plate. The second support plate has a second rotating hole on its sidewall, which penetrates the second support plate. Support legs are symmetrically arranged below the folding plate, located on both sides of the second support plate. A second rotating shaft is fixed to the upper sidewall of the support leg, which penetrates the second rotating hole. A caster wheel is fixed to the lower end of the support leg. A handle is fixed to one end of the folding plate.

[0007] As a preferred technical solution for facilitating the unfolding of the stretcher according to the present utility model, a connecting hole is provided in the middle of one side wall of the second support plate. The connecting hole communicates with the inner side of the second rotating hole, and a plug rod is movably inserted into the inner side of the connecting hole. The plug rod passes through the connecting hole.

[0008] As a preferred technical solution for facilitating the unfolding of a stretcher according to this utility model, a spring is movably sleeved on the outer side of one end of the insertion rod, one end of the spring is fixed on the side wall of the second support plate, and the other end of the spring is fixedly connected to the insertion rod.

[0009] As a preferred technical solution for facilitating the unfolding of the stretcher according to the present invention, the outer wall of the second rotating shaft is provided with a plug hole, and the other end of the plug rod is movably plugged into the inner side of the plug hole.

[0010] As a preferred technical solution for facilitating the unfolding of a stretcher according to this utility model, a fixing plate is fixed in the middle of the top surface of the connecting plate, and an arc-shaped pad is fixed in the middle of the top surface of the fixing plate. The arc-shaped pad is made of flexible material.

[0011] As a preferred technical solution for facilitating the unfolding of the stretcher according to this utility model, the top surface of the fixing plate is symmetrically fixed with blocking blocks, and the blocking blocks are located on both sides of the arc-shaped pad.

[0012] As a preferred technical solution for facilitating the unfolding of a stretcher according to this utility model, a first support plate is fixed to the bottom surface of the folding plate, and the first support plate is located on one side of the second support plate.

[0013] As a preferred technical solution for facilitating the unfolding of the stretcher according to this utility model, a reinforcing plate is fixed to the lower side wall of the outrigger.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention allows for easy folding and storage by flipping the stretcher fabric so that its top surface faces down. This flips the outriggers, causing the second rotating shaft to rotate inside the second rotating hole. Once the reinforcing plate contacts the folding plate, the outriggers can be laid flat for folding and storage. Then, the folding plate is flipped 90 degrees, and the first rotating shaft rotates synchronously inside the first rotating hole, causing the folding plate to rotate along with the outriggers, bringing the stretcher fabrics on both sides closer together, thus completing the folding and storage process. This reduces the space occupied by half. Unfolding is simply the reverse of the above steps, which facilitates transportation and reduces the space required for transport. More rescue equipment can be transported at once, and the quick unfolding during use improves rescue efficiency.

[0016] When this utility model is deployed, the outrigger is fixed by inserting a connecting rod into the inner side of the connecting hole on the outer wall of the second rotating shaft, preventing the second rotating shaft from rotating inside the second rotating hole, thus preventing the outrigger from folding and ensuring stability during rescue use. Simply pull the connecting rod to move it out of the connecting hole, and the outrigger can be flipped and folded. The operation is simple and greatly improves the speed of folding and unfolding.

[0024] Example 1

[0025] Please refer to Figures 1-4. The present invention provides the following technical solution: a stretcher that is easy to unfold, including a connecting plate 1, a fixing plate 11 fixed in the middle of the top surface of the connecting plate 1, and an arc-shaped pad 111 fixed in the middle of the top surface of the fixing plate 11. The arc-shaped pad 111 is made of flexible material. The arc-shaped pad 111 can improve the flexible support at the gaps in the stretcher fabric 2 on both sides, which is conducive to maintaining the comfort of the rescued person when using it.

[0026] Referring to Figures 1, 2, and 3, specifically, one end of the folding plate 21 is fixed with a handle 24 for rescuers to grip and push the person being rescued. The sidewall of the connecting plate 1 is symmetrically provided with first rotating holes 12 for the rotation of the first rotating shaft 221. The first rotating holes 12 penetrate the connecting plate 1. A stretcher cloth 2 is symmetrically provided above the connecting plate 1 to provide support for the person being rescued. The sidewall of the stretcher cloth 2 is symmetrically fixed with folding plates 21 to stabilize the stretcher cloth 2 and allow the overall structure to fold. A fixing block 22 is fixed to the bottom edge of the folding plate 21 to fix the first rotating shaft 221. The sidewall of the fixing block 22 is fixed with the first rotating shaft 221 for the folding plate 21 to be flipped and folded. The first rotating shaft 221 passes through the first rotating hole 12. The top surface of the fixing plate 11 faces... The device is equipped with a fixed blocking block 112 to prevent the folding plates 21 on both sides from flipping upwards during use, thus maintaining stability. The blocking block 112 is located on both sides of the arc-shaped pad 111. The bottom surface of the folding plate 21 is fixed with a first support plate 23 to support the stretcher cloth 2 and enhance its performance. The first support plate 23 is located on one side of the second support plate 25. In this solution, the stretcher cloth 2 is flipped so that the top surface of the stretcher cloth 2 faces down, and then the folding plates 21 on both sides are flipped. The first rotating shaft 221 rotates synchronously inside the first rotating hole 12, and the stretcher cloth 2 on both sides can gradually become vertical and move closer to each other to complete the overall folding. This can reduce the space occupied by half, improve the space utilization rate in the rescue and transportation process, and unfolding is also convenient, which is conducive to improving rescue efficiency.

[0027] Example 2

[0028] In another embodiment of this solution, referring to Figures 1, 2, and 4, specifically, a second support plate 25 is fixed to the other side of the bottom surface of the folding plate 21 to provide support for the stretcher fabric 2. The side wall of the second support plate 25 is provided with a second rotating hole 251 for the rotation of the second rotating shaft 263. The second rotating hole 251 passes through the second support plate 25. Support legs 26 are symmetrically arranged below the folding plate 21 to support the folding plate 21. The support legs 26 are located on both sides of the second support plate 25. The upper side wall of the support leg 26 is fixed with a second rotating shaft 263 for the folding and turning of the support leg 26. The second rotating shaft 263 passes through the second rotating hole 251. The lower end of the outrigger 26 is fixed with a caster wheel 261, which can facilitate the movement of the rescued person by the rescuer. The lower side wall of the outrigger 26 is fixed with a reinforcing plate 262 to enhance the lateral strength of the outrigger 26. In this solution, the outrigger 26 can be flipped over so that the second rotating shaft 263 rotates inside the second rotating hole 251, and the outrigger 26 can be flipped flat so that the reinforcing plate 262 contacts the folding plate 21 to complete the storage of the outrigger 26. To unfold, the outrigger 26 can be flipped in the opposite direction. The operation is simple and convenient and helps to improve efficiency.

[0029] Example 3

[0030] In another embodiment of this solution, referring to Figures 1, 2, and 4, specifically, a connecting hole 252 is provided in the middle of one side wall of the second support plate 25 for connecting the insertion rod 27. The connecting hole 252 communicates with the inner side of the second rotating hole 251. The insertion rod 27 is movably inserted into the inner side of the connecting hole 252, which can restrict the rotation of the second rotating shaft 263. The insertion rod 27 passes through the connecting hole 252. A spring 271 is movably sleeved on the outer side of one end of the insertion rod 27, which can apply an elastic tension to the insertion rod 27. One end of the spring 271 is fixed to the side of the second support plate 25. On the wall, the other end of the spring 271 is fixedly connected to the plug rod 27. The outer wall of the second rotating shaft 263 is provided with a plug hole 264, which is used to cooperate with the plug rod 27 to restrict the rotation of the second rotating shaft 263. The other end of the plug rod 27 is movably inserted into the inside of the plug hole 264. In this solution, the support leg 26 can be flipped and folded simply by pulling the plug rod 27 out of the plug hole 264, which facilitates the storage of the support leg 26. When in use, the plug rod 27 is inserted into the inside of the plug hole 264, which can keep the support leg 26 stable and prevent the support leg 26 from shaking during use.

[0031] The working principle and usage process of this utility model:

[0032] When in use, rescuers can place the person being rescued on the stretcher cloth 2 and move the person by grasping the handle 24. The outriggers 26 and casters 261 can save the rescuers' physical exertion. The flexible arc-shaped pad 111 on the top surface of the fixing plate 11 can provide support for the person being rescued in the gap between the two stretcher cloths 2, enhancing comfort. In addition, the two blocking blocks 112 on the top surface of the fixing plate 11 are located between the folding plates 21 on both sides, which can prevent the folding plates 21 from flipping upward, thereby maintaining the overall stability of the stretcher.

[0033] When folding is required for transport, first rotate the stretcher cloth 2 180 degrees so that the top surface of the stretcher cloth 2 is facing down. Then pull the plug rod 27 to stretch the spring 271. The plug rod 27 moves out of the plug hole 264, and the support leg 26 can be rotated so that the second rotating shaft 263 rotates inside the second rotating hole 251. When the reinforcing plate 262 contacts the folding plate 21, the support leg 26 is flattened and stored. Finally, rotate the folding plates 21 on both sides so that the first rotating shaft 221 rotates inside the first rotating hole 12. The two stretcher cloths 2 come closer to each other, and the overall folding and storage is completed, reducing the space occupied by half and making it convenient for loading and transport.

[0034] When unfolding for use, the opposite is true. First, flip the two folding plates 21 on both sides to separate them so that the top surface of the stretcher cloth 2 is facing down and is on the same horizontal plane as the arc-shaped pad 111. Then, flip the outrigger 26 ninety degrees so that the outrigger 26 is perpendicular to the second support plate 25. Under the tension of the spring 271, the insertion rod 27 automatically inserts into the inside of the insertion hole 264 to fix the outrigger 26. Then, flip the stretcher cloth 2 one hundred and eighty degrees so that its top surface is facing up. The unfolding work is now complete and rescue operations can be carried out.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
