Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a field training protective and medical transport device and its usage method. Background Technology

[0002] In field training, protective equipment and medical transport equipment play a crucial role. Soldiers undergo high-intensity training in complex and ever-changing battlefield environments, thus requiring comprehensive protective equipment to safeguard themselves from injury. Simultaneously, if a soldier is injured during training, efficient medical transport equipment can quickly transport them to a safe area for treatment.

[0003] The existing field training protective and medical transport equipment has the following shortcomings in use:

[0004] 1. In existing technologies, during field training, trainees mostly wear protective training suits for protection, but the protective effect of these suits is limited. When trainees fall while training on slopes or uneven terrain, their arms and legs are extremely vulnerable to impacts from branches and rocks, leading to injuries.

[0005] 2. When it is necessary to transfer injured trainees to a medical facility for treatment, relying solely on medical personnel to manually carry stretchers back and forth will not only significantly prolong the treatment waiting time, but also increase the physical burden on medical personnel due to the weight of the stretchers, resulting in low rescue efficiency and increasing the uncertainty and risks in the rescue process.

[0006] To address the aforementioned problems, this invention proposes a field training protective and medical transport device and its usage method. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing equipment that cannot effectively protect the arms and legs and is inconvenient for transporting trainees, and to propose a field training protective and medical transport device and its usage method.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A field training protective and medical transport device includes two first protective plates and a second protective plate. A first rotating shaft is fixed to the side of each of the two second protective plates that is far apart from each other. The two first protective plates are respectively rotatably sleeved on the outer wall of the corresponding first rotating shaft. A second rotating shaft is rotatably passed through the inside of each of the two second protective plates. A waist protective plate is fixed to the side of each of the two second rotating shafts that is close to each other for waist protection. A protective back plate is fixed to the top of the waist protective plate for back protection of the user.

[0010] The wearable structure is provided on the first protective plate, the second protective plate, and the waist protective plate, for wearing the first protective plate, the second protective plate, and the waist protective plate on the user's body;

[0011] A positioning structure is provided between the first protective plate, the second protective plate, and the waist protective plate to fit together the first protective plate, the second protective plate, and the waist protective plate to form a whole.

[0012] A transport structure is provided on the first protective plate and the protective back plate to transport the first protective plate, the second protective plate and the waist protective plate that form a whole.

[0013] In one possible design, the wearable structure includes a first groove on one side of both the first and second protective plates, with a first fixing shaft fixed within the first groove. A restraint strap is fixed to one side of both the second and first protective plates, and the restraint strap engages with the adjacent first fixing shaft. Two interlocking Velcro straps are provided on one side of each restraint strap for securing the user's legs to the corresponding first and second protective plates. Second fixing shafts are fixed to both ends of the waist protective plate. A first connecting strap is fitted onto the outer wall of each of the two second fixing shafts. A first male buckle and a first female buckle are fixed to the adjacent ends of the two first connecting straps, and the first male buckle and the first female buckle interlock to secure the waist protective plate to the user's waist. Two shoulder straps are fixed to the top of the waist protective plate, with a second male buckle fixed to the bottom of each shoulder strap. A second female buckle is fixed to the top of each of the two restraint straps. The buckle engages with the corresponding second male buckle to increase the stability of the restraint strap. A second connecting strap is fixed to the side of each shoulder strap that is close to each other. A third male buckle and a third female buckle are fixed to the ends of the two second connecting straps that are close to each other, and the third male buckle and the third female buckle engage with each other to limit the position of the two shoulder straps. The first protective plate and the second protective plate are respectively attached to the calf and thigh. One end of the corresponding restraint strap extends to the first groove and passes through the first fixing shaft. The first and second protective plates are then fixed to the user's calf and thigh via Velcro fasteners. Next, the first male buckle and the first female buckle engage to restrain the waist protection plate around the user's waist. Then, the second male buckle and the second female buckle are used to drape the shoulder straps over the user's shoulders, allowing the user to carry the waist protection plate, the first protective plate, and the second protective plate on their back. Additionally, the third male buckle and the third female buckle engage to limit the position of the two shoulder straps, preventing them from detaching from the shoulders.

[0014] In one possible design, the positioning structure includes two fixing blocks, each fixed to one side of the two first protective plates away from each other. Each fixing block has a first bolt threaded through it. The outer walls of the two ends of the two first rotating shafts away from each other are provided with multiple first positioning holes, which engage with the first bolts to brake the first rotating shafts and the first protective plates. Each end of the two second rotating shafts away from each other is fixed with a fixing plate, and each fixing plate has a fourth bolt threaded through it. The waist protective plates have second positioning holes on their opposite sides, and the fourth bolts engage with these holes to brake the waist and second protective plates. Tightening the first bolt inserts it into the first positioning hole to brake the first and second protective plates. Tightening the fourth bolt inserts it into the second positioning hole to brake the waist and second protective plates, thus forming a single unit with the first, second, and waist protective plates and the protective backplate, facilitating the later transfer of injured personnel.

[0015] In one possible design, the transport structure includes two second grooves, each located on the side of the two first protective plates away from the first groove. A fixing post is fixed to the inner wall of one side of each of the two second grooves. A damping shaft is slidably fitted onto the outer wall of each of the two fixing posts. A lead screw is fitted onto the outer wall of each of the two damping shafts. A threaded cylinder is threaded onto the outer wall of one of the lead screws to connect the two lead screws as a whole. Each of the two lead screws has a rope hole for connecting a pull rope to the lead screw. Pulling the lead screw out of the second groove and rotating it causes one end of the two lead screws to align with each other. Rotating the threaded cylinder connects the two lead screws as a whole, ensuring the stability of the user's legs during transport. Furthermore, the pull rope passing through the rope hole allows other trainees to lift the lead screw.

[0016] In one possible design, the transport structure further includes a storage slot located on the side of the protective backplate away from the restraint straps. A rotating column is rotatably connected within the storage slot. A head support plate for supporting the user's head is fixedly fitted onto the outer wall of the rotating column. The top of the protective backplate has two circular holes. Both ends of the rotating column extend into the two circular holes and are fixed with gears. A lifting rod is slidably connected within each of the two circular holes. A rack is fixed to one side of each of the two circular holes, and the rack meshes with the gear to drive the head support plate out of the storage slot. Pulling the lifting rod outward causes the rotating column to rotate through the engagement of the rack and gear, thus rotating the head support plate out of the storage slot. The head support plate can then support the user's head. Subsequently, other trainees can use the lifting rod and the rope passing through the rope hole to use the first protective plate, second protective plate, waist protective plate, and protective backplate as a stretcher to transport the injured person.

[0017] In one possible design, a magnetic ring is fixedly sleeved on the outer wall of the fixed column, and an iron block is fixed to one end of the damping shaft. The iron block and the magnetic ring generate a magnetic attraction force to stably house the lead screw and the damping shaft in the second groove.

[0018] In one possible design, a storage pouch is fixed to the side of the second protective plate away from the restraint strap.

[0019] In one possible design, the bottom of the waist protection plate is fixed with two bases, and a common storage rod is rotatably inserted through the two bases. Two coil springs, fixedly connected to one side of adjacent bases, are fitted onto the outer wall of the storage rod. The ends of the two coil springs, close to each other, are fixedly connected to the outer wall of the storage rod. A canvas is wrapped around the outer wall of the storage rod, positioned between the two coil springs. A connecting plate is fixed to the bottom end of the canvas, and two connectors are fixed to one side of the connecting plate. Connecting buckles are fixed to one side of each of the two second protection plates, and the connectors and connecting buckles are inserted into each other. A third bolt is threaded through the internal thread of the connecting buckle, with one end of the third bolt passing through the connector, used to fix the connector and connecting buckle. The canvas is pulled by the connecting plate, inserting the connector into the connecting buckle, and the third bolt secures the connector and connecting buckle. The canvas protects the injured person's buttocks, preventing injury from branches, rocks, and insects in the wild during transport.

[0020] In one possible design, the waist protection plate has two hydraulic chambers, each connected to two second positioning holes. A piston plate is slidably connected to each of the second positioning holes, and the piston plate engages with a fourth bolt. A spring is fixed to one side of each piston plate, and one end of each spring is fixedly connected to the inner wall of one side of each hydraulic chamber. A pin is slidably inserted through the bottom inner wall of each hydraulic chamber. The outer wall of the threaded cylinder has two sets of braking components, each consisting of multiple pin holes, with the pins engaging with the pin holes to brake the retractable rod. During the tightening of the fourth bolt into the second positioning hole, the piston plate is moved, and under the action of hydraulic oil inside the hydraulic chamber, the pin is pushed downwards and inserted into the pin hole to brake the retractable rod, thus providing support for the injured person's legs with the canvas.

[0021] This application discloses a method for using a field training protective and medical transport device, comprising the following steps:

[0022] S1. Wearing protective equipment: The first and second protective plates are placed against the calves and thighs, secured with restraint straps, and the male and female buckles are used to restrain the waist protective plate. The male and female buckles of the shoulder straps are used to secure the shoulder straps, and the male and female buckles of the shoulder straps limit the shoulder straps.

[0023] S2. Connect the lead screw to stabilize the legs: Pull out and rotate the lead screw, connect it through the threaded cylinder after docking, and pass the rope through the rope hole for easy lifting.

[0024] S3. Brake all protective plates to form a whole: Tighten the first bolt and insert it into the first positioning hole, tighten the fourth bolt and insert it into the second positioning hole, and brake all protective plates.

[0025] S4. Rotate the head support plate and transfer the wounded: The lifting rod drives the rotating column through the cooperation of rack and pinion to rotate the head support plate, and the wounded are transferred by lifting rod and rope.

[0026] S5. Protect the injured person's buttocks and support their legs: Pull the canvas with the connecting plate, insert the connector into the connecting buckle and fix it with the third bolt, push the piston plate to move, and the pin rod moves down and inserts into the pin hole to brake the storage rod.

[0027] Beneficial effects: In this invention, a first rotating shaft is fixed to the side of each of the two second protective plates that are far apart from each other. The two first protective plates are respectively rotatably sleeved on the outer wall of the corresponding first rotating shaft. A second rotating shaft is rotatably passed through the inside of each of the two second protective plates. The same waist protective plate is fixed to the side of each of the two second rotating shafts that are close to each other. By fixing the first protective plate, the second protective plate and the waist protective plate to the user's calves, thighs and waist respectively, and at the same time, the protective back plate is close to the back, so as to protect the user's legs and back in a timely manner during training. The user still has a protective effect in harsh environments.

[0028] In this invention, a fixing post is fixed to one side of the inner wall of each of the two second grooves, and a damping shaft is slidably sleeved on the outer wall of each of the two fixing posts. A lead screw is sleeved on the outer wall of each of the two damping shafts, and a threaded cylinder is threaded onto the outer wall of one of the lead screws to form the two lead screws into a whole. The lead screw is pulled out of the second groove and rotated so that one end of the two lead screws is connected to each other. By rotating the threaded cylinder, the two lead screws are connected into a whole through the threaded cylinder, ensuring the stability of the user's legs during the transfer. Furthermore, by passing a rope through the rope hole, other trainees can pull the lead screw to quickly transfer the injured person.

[0029] In this invention, a rotating column is rotatably connected inside the storage slot. A head support plate is fixedly sleeved on the outer wall of the rotating column. Gears are fixed at both ends of the rotating column. A lifting rod is slidably connected inside each of the two circular holes. A rack is fixed on one side of each of the two circular holes. When the lifting rod is pulled outward, the lifting rod drives the rotating column to rotate through the cooperation of the rack and gear. The rotating column rotates the head support plate out of the storage slot, so that the head support plate can support the user's head. Afterward, other trainees can use the lifting rod and the rope passing through the rope hole to use the first protective plate, the second protective plate, the waist protective plate, and the protective back plate as a stretcher to complete the transfer of the wounded.

[0030] In this invention, the lower legs and thighs can be protected during field training, reducing the risk of leg injury to the user during rolling. When it is necessary to transfer the wounded, the first protective plate, the second protective plate and the first fixed shaft are integrated to form a simple stretcher, which can easily complete the transfer of the wounded and save the physical exertion of medical personnel.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] Example 1: Refer to Figures 1-7 The transfer equipment relates to the field of medical device technology. The equipment mainly includes two first protective plates 1, two second protective plates 3, a waist protective plate 9, a protective back plate 10, a wearing structure, a positioning structure, and a handling structure.

[0046] Reference Figure 1 and Figure 2 Each of the two second protective plates 3 has a first rotating shaft 2 fixed to its opposite side. The two first protective plates 1 are rotatably mounted on the outer wall of their respective first rotating shafts 2, allowing the first protective plate 1 to rotate relative to the second protective plate 3. A second rotating shaft 8 rotatably passes through each of the two second protective plates 3. A common waist protective plate 9 is fixed to the side of the two second rotating shafts 8 that is close to each other. A protective back plate 10 is fixed to the top of the waist protective plate 9. Thus, the waist protective plate 9 and the protective back plate 10 can protect the user's waist and back.

[0047] Reference Figure 2 , Figure 5 and Figure 6 The wearable structure includes a first groove 4 located on one side of the first protective plate 1 and the second protective plate 3, with a first fixing shaft 5 fixed within the first groove 4. A restraint strap 6 is fixed to one side of both the second protective plate 3 and the first protective plate 1, and the restraint strap 6 engages with the adjacent first fixing shaft 5. Two interlocking Velcro straps are provided on one side of the restraint strap 6 for securing the user's corresponding legs to the corresponding first protective plate 1 or second protective plate 3. Second fixing shafts 11 are fixed to both ends of the waist protective plate 9, and first connecting straps 12 are fitted onto the outer walls of both second fixing shafts 11. A first male buckle 13 and a first female buckle 14 are fixed to the ends of the two first connecting straps 12 that are close to each other, respectively, and the first male buckle 13 and the first female buckle 14 engage to secure the waist protective plate 9 to the user's waist. Two shoulder straps 15 (50mm ± 1mm ​​wide) are fixed to the top of the waist protection plate 9. A second male buckle 16 is fixed to the bottom end of each shoulder strap 15. A second female buckle 17 is fixed to the top of each of the two restraint straps 6. The second female buckle 17 engages with the corresponding second male buckle 16 to increase the stability of the restraint straps 6. A second connecting strap 18 is fixed to the side of each shoulder strap 15 that is close to each other. A third male buckle 19 and a third female buckle 20 are fixed to the end of each second connecting strap 18 that is close to each other. The third male buckle 19 and the third female buckle 20 engage with each other to limit the movement of the two shoulder straps 15.

[0048] In actual use, the user places the first protective plate 1 against their calves and the second protective plate 3 against their thighs. One end of the restraint strap 6 extends to the first groove 4 and passes through the first fixing shaft 5, where it is secured to the user's calves and thighs via Velcro fasteners. Next, the waist protection plate 9 is secured to the user's waist using the first male buckle 13 and the first female buckle 14. Then, the shoulder straps 15 are draped over the user's shoulders using the second male buckle 16 and the second female buckle 17, allowing the waist protection plate 9, the first protective plate 1, and the second protective plate 3 to be carried on the user's back. Furthermore, the third male buckle 19 and the third female buckle 20 limit the movement of the two shoulder straps 15, preventing them from slipping off the shoulders.

[0049] Reference Figure 1 , Figure 2 and Figure 5The positioning structure includes two fixing blocks 21, which are respectively fixed to the opposite sides of the two first protective plates 1. Each fixing block 21 has a threaded first bolt 22. The outer walls of the opposite ends of the two first rotating shafts 2 are provided with multiple first positioning holes 23, which cooperate with the first bolts 22 to brake the first rotating shafts 2 and the first protective plates 1. Each of the opposite ends of the two second rotating shafts 8 is fixed with a fixing plate 50, and each fixing plate 50 has a threaded fourth bolt 51. The opposite sides of the waist protective plates 9 are provided with second positioning holes 47, which cooperate with the fourth bolts 51 to brake the waist protective plates 9 and the second protective plates 3.

[0050] When it is necessary to fix the first protective plate 1, the second protective plate 3, the waist protective plate 9, and the protective back plate 10 into a whole, the first bolt 22 can be tightened so that the first bolt 22 is inserted into the first positioning hole 23 to brake the first protective plate 1 and the second protective plate 3. At the same time, the fourth bolt 51 is tightened so that the fourth bolt 51 is inserted into the second positioning hole 47 to brake the waist protective plate 9 and the second protective plate 3. In this way, the first protective plate 1, the second protective plate 3, the waist protective plate 9, and the protective back plate 10 form a whole, which facilitates the subsequent transfer of injured personnel.

[0051] The handling structure can be installed on the first protective plate 1 and the protective back plate 10 to facilitate the handling of the entire equipment when needed.

[0052] Reference Figure 3 and Figure 4 The transport structure includes two second grooves 24 respectively provided on the side of the two first protective plates 1 away from the first groove 4. These two second grooves 24 are used to accommodate and secure subsequent transport components. A fixing post 25 is fixed to the inner wall of each of the two second grooves 24. A damping shaft 26 is slidably sleeved on the outer wall of the fixing post 25. A lead screw 28 is sleeved on the outer wall of the damping shaft 26. The damping shaft 26 allows the lead screw 28 to rotate on the shaft and have a certain damping force to maintain its positional stability. A threaded sleeve 29 is threaded onto the outer wall of one lead screw 28. This threaded sleeve 29 is used to connect the two lead screws 28 into a whole. Each lead screw 28 has rope holes 30 for connecting a pull rope to the lead screw 28, so that other trainees can pull the lead screw 28 by pulling the rope, thereby assisting in the transfer of the wounded.

[0053] In use, the lead screw 28 can be pulled out from the second groove 24 and rotated to align one end of the two lead screws 28 together. Then, the threaded cylinder 29 is rotated, and the two lead screws 28 are tightly connected into a whole through the thread action of the threaded cylinder 29. This ensures that the user's legs remain stable during transport and will not be injured due to swaying. At the same time, by pulling the rope through the rope hole 30, other trainees can easily lift the lead screw 28 to assist in the transport of the injured. According to the tensile test (GB / T 3923.1-2013), the rope hole 30 (hole diameter Φ6mm) can withstand a maximum instantaneous tensile force ≥800N, which meets the strength requirements for two people to lift and transport together.

[0054] Reference Figure 6 and Figure 7 In addition, a storage slot 31 is provided on the side of the protective back panel 10 away from the restraint strap 6. A rotating column 32 is rotatably connected inside the storage slot 31, and a head support plate 33 for supporting the user's head is fixedly fitted on the outer wall of the rotating column 32. The top of the protective back panel 10 has two round holes 34, and both ends of the rotating column 32 extend into the two round holes 34 respectively and are fixed with gears 37. A lifting rod 35 is slidably connected inside each of the two round holes 34, and a rack 36 is fixed to one side of each of the two round holes 34, and the rack 36 meshes with the gear 37.

[0055] In use, the lifting rod 35 can be pulled outwards, driving the rotating column 32 to rotate via the engagement of the rack 36 and gear 37. The rotation of the rotating column 32 causes the head support plate 33 to rotate out of the storage slot 31, thus providing head support for the user. This not only improves user comfort but also further ensures stability during transport. Afterwards, other trainers can use the lifting rod 35 and the rope passing through the rope hole 30 to use the first protective plate 1, second protective plate 3, waist protective plate 9, and protective back plate 10 as a stretcher to transport the injured.

[0056] Reference Figure 4 To further improve the stability of the lead screw 28 and the damping shaft 26 within the second groove 24, a magnetic ring 27 can be fixedly sleeved on the outer wall of the fixing post 25, and an iron block can be fixed to one end of the damping shaft 26. In this way, a magnetic attraction can be generated between the iron block and the magnetic ring 27, thereby stably housing the lead screw 28 and the damping shaft 26 within the second groove 24, preventing them from shaking or falling off when not in use.

[0057] Reference Figure 1 and Figure 2On the side of the second protective plate 3 away from the restraint strap 6, a storage pouch 7 is fixedly connected by means of sewing or gluing. The storage pouch 7 is used to store first aid supplies or other necessities for quick access during field training or medical transport.

[0058] Through the specific implementation methods described above, it can be ensured that the equipment provides comprehensive protection for the injured during field training or medical transport, and avoids secondary injuries that may occur during transport. At the same time, the equipment has a simple structure, is easy to operate, and has high practicality and feasibility.

[0059] Example 2: Reference Figures 8-10 At the bottom of the waist protection plate 9, two bases 38 are fixed by welding or bolting. A common storage rod 39 rotatably passes through both bases 38, allowing free rotation within the bases 38. Two coil springs 40 are fitted onto the outer wall of the storage rod 39. One end of each coil spring 40 is fixedly connected to one side of an adjacent base 38, and the other end is fixedly connected to the outer wall of the storage rod 39. The coil springs 40 ensure that the storage rod 39 maintains a certain tension when no external force is applied. The preload of the coil springs 40 (1.2mm wire diameter, 65Mn steel material) is set to 5-8 N·m, ensuring that the static torque deviation of the storage rod 39 in its free state is ≤0.3 N·m, meeting the self-locking requirement of the canvas 41 without external force. A layer of canvas 41 is wound around the outer wall of the storage rod 39, located between the two coil springs 40, to protect the injured person's buttocks. A connecting plate 42 is fixed to the bottom end of the canvas 41 by sewing or other means. Two connectors 43 are fixed to one side of the connecting plate 42 by welding or bolting. On one side of each of the two second protective plates 3, a connecting buckle 44 is fixed by welding or bolting, and the connectors 43 can be inserted into the connecting buckles 44. A third bolt 45 is threaded through the connecting buckle 44, and one end of the third bolt 45 can pass through the connector 43, thereby fixing the connector 43 and the connecting buckle 44.

[0060] In use, the canvas 41 is pulled by the connecting plate 42 to unfold the canvas 41, and then the connector 43 is inserted into the connector buckle 44. The connector 43 and the connector buckle 44 are fixed by tightening the third bolt 45. The canvas 41 protects the buttocks of the injured person and prevents the buttocks from being injured by branches, stones and insects in the wild during the transportation process.

[0061] refer to Figure 10Two hydraulic chambers 46 are provided within the waist protection plate 9, and these two hydraulic chambers 46 are respectively connected to two second positioning holes 47. A piston plate 49 is slidably connected to each of the two second positioning holes 47, and the piston plate 49 can cooperate with the fourth bolt 51. A spring 48 is fixed to one side of each piston plate 49 near each other by welding or other means, and one end of the spring 48 is fixedly connected to one inner wall of the hydraulic chamber 46. The spring 48 allows the piston plate 49 to maintain a certain position when no external force is applied. A pin 52 is slidably passed through the bottom inner wall of each of the two hydraulic chambers 46. Two sets of braking components are provided on the outer wall of the threaded cylinder 29. These two sets of braking components consist of multiple pin holes 53, and the pin 52 can be inserted into the pin holes 53 to brake the receiving rod 39.

[0062] In use, when the canvas 41 needs to support the injured person's legs, the fourth bolt 51 can be tightened, inserting it into the second positioning hole 47 and pushing the piston plate 49 to move. The movement of the piston plate 49 compresses the hydraulic oil in the hydraulic chamber 46, causing the pin 52 to move downward under the action of the hydraulic oil and insert into the pin hole 53, braking the retractable rod 39. In this way, the retractable rod 39 can no longer rotate, thus keeping the canvas 41 in an unfolded state, providing support for the injured person's legs.

[0063] A method for using a field training protective and medical transport device includes the following steps:

[0064] S1. When worn, the first protective plate 1 and the second protective plate 3 are respectively attached to the lower leg and the thigh. One end of the corresponding restraint strap 6 extends to the first groove 4 and passes through the first fixing shaft 5. The first protective plate 1 and the second protective plate 3 are fixed to the user's lower leg and thigh by the Velcro that matches them. Then, the waist protection plate 9 can be restrained to the user's waist by the cooperation of the first male buckle 13 and the first female buckle 14. Then, the shoulder strap 15 is placed on the user's shoulders by the second male buckle 16 and the second female buckle 17, so that the user can carry the waist protection plate 9, the first protective plate 1 and the second protective plate 3 on his back. In addition, the cooperation of the third male buckle 19 and the third female buckle 20 can limit the two shoulder straps 15 to prevent the shoulder straps 15 from coming off the shoulders. Therefore, when the user falls and rolls on the slope, the first protective plate 1 and the second protective plate 3 can protect the legs, while the protective back plate 10 can protect the back.

[0065] S2. When a user is injured and needs to be transferred to the treatment area, pull the lead screw 28 out of the second groove 24 and rotate it so that one end of the two lead screws 28 are connected to each other. Rotate the threaded cylinder 29 to connect the two lead screws 28 into a whole through the threaded cylinder 29, ensuring the stability of the user's legs during the transfer. And by passing the rope through the rope hole 30, other trainees can lift the lead screw 28.

[0066] S3. Next, the user lies flat on the ground and the first bolt 22 is tightened. The first bolt 22 is inserted into the first positioning hole 23 to brake the first protective plate 1 and the second protective plate 3. The fourth bolt 51 is tightened and inserted into the second positioning hole 47 to brake the waist protective plate 9 and the second protective plate 3. This makes the first protective plate 1, the second protective plate 3, the waist protective plate 9 and the protective back plate 10 form a whole, which is convenient for the later transfer of the injured person.

[0067] S4. Additionally, pull the lifting rod 35 outward. The lifting rod 35 drives the rotating column 32 to rotate through the cooperation of the rack 36 and the gear 37. The rotating column 32 rotates the head support plate 33 out of the storage slot 31, so that the head support plate 33 can support the user's head. Afterward, other trainees can use the lifting rod 35 and the rope passing through the rope hole 30 to use the first protective plate 1, the second protective plate 3, the waist protective plate 9 and the protective back plate 10 as a stretcher to complete the transfer of the wounded.

[0068] S5. In addition, before the injured person lies flat, the canvas 41 is pulled by the connecting plate 42 and the connector 43 is inserted into the connector buckle 44. The connector 43 and the connector buckle 44 are fixed by the third bolt 45. The canvas 41 protects the injured person's buttocks to prevent injury from branches, stones and insects in the wild during the transfer. Then, when the fourth bolt 51 is tightened and inserted into the second positioning hole 47, the piston plate 49 is pushed to move. Then, under the action of the hydraulic oil in the hydraulic chamber 46, the pin 52 is pushed down and inserted into the pin hole 53 to brake the storage rod 39, so that the canvas 41 supports the injured person's legs.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
