Description

Technical Field

[0001] The invention relates to the technical field of water disaster relief equipment, and in particular to a rescue stretcher device used for water disaster relief. Background Art

[0002] Disaster relief on water is a crucial task, and the rescue stretcher device plays a key role in the rescue process. However, the existing rescue stretcher devices on water often have some shortcomings.

[0003] The current water rescue stretchers are relatively simple in structure and lack effective buffering design. In the actual water rescue and transportation process, due to the influence of water flow and the carrying action itself, the stretcher is prone to produce large vibrations; this vibration will not only cause discomfort to the rescued, but may also have an adverse effect on the rescued person's condition, especially for some rescued persons with serious injuries or in special physical conditions, which may cause the wound to worsen or cause other complications. For example, when transporting the rescued through water, the stretcher lacks a good buffering mechanism, and contact with the water surface or collision with other objects will cause strong vibrations to be transmitted to the rescued. This greatly reduces the quality and effectiveness of the rescue, and also brings potential risks to the subsequent rehabilitation of the rescued.

[0004] In addition, considering the special environment of water rescue, it is difficult to adjust the height of the existing stretcher according to needs, which easily causes the rescued person to contact with water, making it difficult to better protect the rescued person and also affecting the safety and effectiveness of the rescue.

[0005] Therefore, in order to improve the efficiency and quality of water rescue and ensure the safety and health of the rescued, it is urgently necessary to improve the structure of the existing water rescue stretcher device, increase buffer protection functions and adjustable height components to reduce the adverse vibration effects on the rescued during transportation.

[0011] As a further feature of the present invention, the buffer mechanism further includes a buffer air bag fixedly connected to the center of the bottom of the buffer connecting plate, and the bottom of the buffer air bag is fixedly connected to the bottom inner wall of the buffer box.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention is not only convenient for water rescue and transportation, but also, when the stretcher generates large vibrations due to the influence of water flow and excessive transportation action itself, a part of the excessive vibrations can be greatly consumed through the torsional deformation of the torsion buffer spring and the deformation of the vertical buffer spring.

[0019] 2. In the present invention, the compression buffering of the gas inside the buffer airbag can further play the role of air pressure buffering; when the vibration intensity is further too large, the buffer airbag will be further compressed and expanded on both sides, so that the buffer airbag can contact with the linkage block after expansion and make the two linkage blocks move away from each other. When the two linkage blocks move away from each other, the transverse buffer spring is squeezed, and the outer end of the transverse guide rod is driven to move toward the outer end of the through hole, thereby causing the elastic buffer to be stretched and deformed. In this way, the deformation of the transverse buffer spring and the elastic buffer can further play the role of buffering and energy absorption;

[0020] 3. In the present invention, through the mutual cooperation of multiple buffer mechanisms, the vibration of the entire stretcher during the actual water rescue and transportation process can be greatly reduced, avoiding discomfort to the rescued person due to excessive vibration, and even causing the wounds of some seriously injured people to worsen. This greatly improves the quality and effect of the rescue, and is also conducive to reducing the potential risks brought by the rescued person in the subsequent rehabilitation, ensuring better use effect.

[0021] 4. In the present invention, by providing a foam plastic float, the entire stretcher device can float on the water surface through the foam plastic float, and the rescuer can rotate it without manual carrying, and only needs to control the floating direction of the stretcher on the water, so as to reduce the burden of the rescuer in the water.

[0022] 5. In the present invention, air is inflated into the airtight space in the "V"-shaped foldable sealed airbag, and the "V"-shaped foldable sealed airbag can expand upward and form a supporting effect during the inflation process, so that the support plate and the buffer pad can be adjusted upward as a whole. In this way, by adjusting the overall height of the support plate and the buffer pad, it is helpful to avoid contact with the water surface during the rescue process. At the same time, the gas filled in the "V"-shaped foldable sealed airbag can further play a buffering effect during use, which further makes the overall use effect better; in this way, the rescued person can be better protected, the safety and effectiveness of the rescue can be improved, the efficiency and quality of water rescue can be improved, and the safety and health of the rescued person can be guaranteed.

[0023] In summary, the present invention is not only convenient for water rescue, but also improves the overall structure of the existing water rescue stretcher device, and not only increases the buffer protection function to reduce the adverse vibration effect on the rescued during the transportation process, but also effectively reduces the impact of vibration on the rescued. In addition, taking into account the special environment of water rescue, the design allows the stretcher to float on the water and adjust the height as needed to avoid contact between the rescued and the water; this can better protect the rescued, improve the safety and effectiveness of the rescue; ensure that the performance of the entire stretcher is better, greatly meet the needs of water rescue, and is suitable for promotion and application.

[0035] The buffer mechanism includes a plurality of mounting grooves 101 evenly arranged on the top of the rescue stretcher body 1, a buffer support 9 is fixedly installed in the mounting groove 101, a buffer cavity 901 is provided on the buffer support 9, a buffer support rod 12 is movably installed in the buffer cavity 901, and the top of the buffer support rod 12 is fixedly connected to the bottom of the rescue stretcher body 1; a movable block 13 is movably installed in the buffer cavity 901, and the top of the movable block 13 is fixedly connected to the bottom end of the buffer support rod 12; a rotating shaft 15 is rotatably installed in the buffer cavity 901 below the movable block 13 through a bearing 17, a symmetrically arranged cam 14 is fixedly sleeved on the rotating shaft 15, and the top side of the cam 14 is rollingly connected to the bottom side of the movable block 13; a torsion buffer spring 16 is sleeved on the rotating shaft 15 located on the outer side of the cam 14, one end of the torsion buffer spring 16 is fixedly connected to the side wall of the buffer cavity 901, and the other end of the torsion buffer spring 16 is fixedly connected to the outer side of the cam 14.

[0036] Furthermore, the buffer mechanism also includes a buffer box 19 fixedly mounted on the bottom inner wall of the buffer cavity 901, and the buffer box 19 is located between the inner sides of the two cams 14, and a buffer connecting plate 191 is movably mounted in the buffer box 19, and a buffer connecting rod 18 is fixedly connected to the top of the buffer connecting plate 191, and the top of the buffer connecting rod 18 movably passes through the top of the buffer box 19 and is fixedly connected to the bottom side of the movable block 13, and the buffer connecting rod 18 is also located on the front side of the rotating shaft 15; a vertical buffer spring 192 is also fixedly connected between the buffer connecting plate 191 and the top inner wall of the buffer box 19.

[0037] like Figure 6 As shown, as a further feature, the buffer mechanism also includes a buffer airbag 193 fixedly connected to the bottom center of the buffer connecting plate 191, and the bottom of the buffer airbag 193 is fixedly connected to the bottom inner wall of the buffer box 19; linkage blocks 194 are slidably installed in the horizontal direction on the bottom inner walls of the buffer box 19 on both sides of the buffer airbag 193, and the ends of the two linkage blocks 194 that are away from each other are fixedly connected to a transverse buffer spring 195, and the other end of the transverse buffer spring 195 is fixedly connected to the side wall of the buffer box 19.

[0038] like Figure 6 As shown, as a further step, the ends of the two linkage blocks 194 that are away from each other are also fixedly connected to a transverse guide rod 196, and the transverse buffer spring 195 is movably mounted on the transverse guide rod 196 in the horizontal direction; through holes 197 are provided on the inner walls on both sides of the buffer box 19, and the outer ends of the transverse guide rods 196 are also movably inserted into the through holes 197; grooves 198 are provided on the top inner wall and the bottom inner wall of the through hole 197, and the inner walls of the two grooves 198 are fixedly connected with inclined elastic buffers 199, and the other ends of the elastic buffers 199 are fixedly connected to the outer end portions of the transverse guide rods 196; the elastic buffers 199 are specifically any one of rubber strips, silicone strips, and polyurethane strips.

[0039] like Figure 5 As shown, the protruding part of the cam 14 is set upward, and a rolling groove 131 is provided at the bottom of the movable block 13. A roller 132 is rollingly installed in the rolling groove 131. The bottom of the movable block 13 is rollingly connected to the top of the cam 14 through the roller 132, which can reduce the friction between the movable block 13 and the cam 14, so as to buffer the rotation of the cam 14 and the torsional deformation of the torsion buffer spring 16.

[0040] like Figure 5 As shown, a movable hole 902 is provided on the top inner wall of the buffer cavity 901, and the buffer support rod 12 movably passes through the movable hole 902; fixed guide sliders 903 are fixedly connected to the inner walls on both sides of the movable hole 902, and guide grooves 904 are provided on both sides of the buffer support rod 12, and the two sides of the buffer support rod 12 are slidably connected with the fixed guide sliders 903 in the vertical direction through the guide grooves 904 to play a guiding role.

[0041] like Figure 1-8 The rescue stretcher device shown is used for water disaster relief. When in use, the rescued person is placed on the cushion pad 4 above the rescue stretcher body 1 and fixed by the fixing belt 5. Then the rescuer lifts the entire stretcher through the side U-shaped handle 6 and carries it for water rescue. And it has good buffering performance during transportation and use. When the stretcher vibrates greatly due to the influence of water flow and the excessive movement of the transportation action itself during actual water rescue transportation, the buffer pad 4 can move downward for buffering through the support plate 3, the "V"-shaped foldable sealing airbag 7, the buffer support plate 8 and the buffer support rod 12. When the buffer support rod 12 moves downward for buffering, it will cause the movable block 13 to move downward and prompt the protruding part of the cam to rotate downward, thereby causing the rotating shaft 15 and the torsion buffer spring 16 to twist and deform. In this way, the torsion buffer spring 16 can greatly consume a part of the excessive vibration force through the twisting deformation; and when the movable block 13 moves downward for buffering, it also drives the buffer connecting plate 191 to move downward through the buffer connecting rod 18 and stretches the vertical buffer spring 192. In this way, through the deformation of the vertical buffer spring 192, it can further play a role in shock absorption and energy dissipation.

[0042] like Figure 6As a further improvement, when the buffer connecting plate 191 moves down for buffering, the buffer airbag 193 can also be compressed, so that the compression buffering of the gas inside the buffer airbag 193 can further play the effect of air pressure buffering; when the vibration intensity is further too large, the buffer airbag 193 will be further compressed and expanded on both sides, so that the buffer airbag 193 can contact with the linkage block 194 after expansion and make the two linkage blocks 194 move away from each other (if the vibration intensity is small, they will not contact the linkage blocks 194), and when the two linkage blocks 194 move away from each other, they squeeze the transverse buffer spring 195 and drive the outer end of the transverse guide rod 196 at the same time. It moves toward the outer end of the through hole 197, which further causes the elastic buffer 199 to be stretched and deformed, so that the deformation of the lateral buffer spring 195 and the elastic buffer 199 can further play a role in buffering and absorbing energy; finally, through the mutual cooperation of multiple buffer mechanisms, the vibration of the entire stretcher during the actual water rescue and transportation process can be greatly reduced, avoiding discomfort to the rescued person due to excessive vibration, and even causing the wounds of some seriously injured people to worsen. This greatly improves the quality and effect of the rescue, and is also conducive to reducing the potential risks brought about by the rescued person in the subsequent rehabilitation, ensuring better use effect.

[0043] like Figure 4 , Figure 8 As shown, as a further improvement, by setting a foam plastic float 2, the entire stretcher device can be floated on the water surface through the foam plastic float 2, and the rescuer can rotate it without manual carrying, and only needs to control the floating direction of the stretcher on the water, so as to reduce the rescue burden of the rescuer in the water. At the same time, in order to prevent the patient from contacting the water surface, the air pump 10 can be controlled by the waterproof control switch 20 to inflate the airtight space in the "V"-shaped foldable sealed airbag 7 through the active air pipe 11, and the "V"-shaped foldable sealed airbag 7 can expand upward during the inflation process and form a supporting effect, so that the support plate 3 and the buffer pad 4 can be adjusted upward as a whole (such as Figure 8 As shown in ), by raising the overall height of the support plate 3 and the cushion 4, it is helpful to avoid contact with the water surface during the rescue process. At the same time, the gas filled in the "V"-shaped foldable sealed airbag 7 can further play a buffering effect during use, which further makes the overall use effect better. Finally, the stretcher can not only float on the water, but also adjust the height as needed to avoid contact between the rescued person and the water. At the same time, the gas filled can further play a buffering effect, which can better protect the rescued person, improve the safety and effectiveness of the rescue, improve the efficiency and quality of water rescue, and ensure the safety and health of the rescued person.

[0044] In summary, the present invention improves the overall structure of the existing water rescue stretcher device, not only by adding a buffer protection function to reduce the adverse vibration effect on the rescued during the transportation process, but also effectively reduces the impact of vibration on the rescued. In addition, taking into account the special environment of water rescue, the design allows the stretcher to float on the water and adjust the height as needed to avoid the rescued from contacting the water; this can better protect the rescued, improve the safety and effectiveness of the rescue; ensure that the performance of the entire stretcher is better, greatly meet the needs of water rescue, and is suitable for promotion and application.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
