Description

Technical Field

[0001] This utility model relates to the field of lifting air cushion technology, and in particular to a high-pressure lifting air cushion for rescue. Background Technology

[0002] A high-pressure lifting air cushion is a portable lifting device that uses the rapid expansion of high-pressure gas to generate lifting force. It typically consists of a high-pressure resistant rubber airbag, an inflation connector, a control valve, and an air supply device. By injecting high-pressure air into the air cushion, it generates a large vertical lifting force in a short time, which is used to lift heavy components or cover objects.

[0003] High-pressure lifting air cushions for rescue are inflatable lifting equipment used in emergency rescue, accident handling, and rescue in confined spaces. In existing technologies, the base is usually connected to the air cushion or mounting plate by bolts and nuts to provide stable support. However, this method often requires the use of external tools for installation or disassembly, and the operation steps are cumbersome, which cannot meet the needs of rapid deployment in emergency rescue environments. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-pressure lifting air cushion for rescue, which aims to improve the problem that the connection between the air cushion and the mounting plate via bolts and nuts requires the use of external tools for installation or disassembly, resulting in cumbersome operation steps.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A high-pressure lifting air cushion for rescue includes an air cushion body. An air inlet pipe is fixedly connected inside the air cushion body, and a cap is provided on the outer wall of the air inlet pipe. A load-bearing plate is provided on the upper surface of the air cushion body, and an installation ring is fixedly connected to the lower surface of the air cushion body. A base is provided inside the installation ring, and a hollow block is fixedly connected inside the installation ring. A U-shaped rod is slidably connected inside both the installation ring and the hollow block. A slider is fixedly connected to the outer wall of the U-shaped rod, and a spring is fixedly connected to the outer wall of the slider. The outer wall of the spring is fixedly connected inside the hollow block. A transmission plate is slidably connected to the outer wall of the slider, and a support shaft is rotatably connected inside the transmission plate. A limit block is slidably connected inside the transmission plate, and the outer wall of the limit block is located inside the base. A positioning component is provided on the lower surface of the installation ring.

[0006] The above technical solution allows for the convenient removal of the cap when inflating the air cushion, enabling the air inlet pipe to connect to the inflation component. The inflation component then inflates the air cushion, which contacts the ground via the mounting ring, providing support. The expansion of the air cushion causes the load-bearing plate to move upwards, lifting any object it contacts and thus providing support. The U-shaped rod and its connecting structure facilitate the limiting or releasing of the base, allowing for replacement when the base becomes worn, ensuring the continued usability of the air cushion.

[0007] Preferably, the positioning component includes a positioning rod, the top end of which is fixedly connected to the lower surface of the mounting ring, and the bottom end of which is disposed inside the base.

[0008] Preferably, the outer wall of the slider is slidably connected to the inside of the hollow block, both ends of the support shaft are fixedly connected to the inside of the hollow block, and the outer wall of the limiting block is slidably connected to the inside of the hollow block and the mounting ring.

[0009] Preferably, handles are fixedly connected to both sides of the air cushion body, and a connecting plate is provided on the upper surface of the load-bearing plate, the connecting plate and the base being matched.

[0010] Preferably, the cap has a sealing sleeve inside, the inside of which is fixedly connected to the outer wall of the air intake pipe, and a sealing ring is provided between the cap and the sealing ring.

[0011] Preferably, an L-shaped plate is fixedly connected to the outer wall of the cap, and a fixing block is slidably connected to the outer wall of the L-shaped plate. The outer wall of the fixing block is fixedly connected to the outer wall of the air intake pipe.

[0012] Preferably, a concave block is slidably connected inside the fixed block, the interior of the concave block is disposed on the outer wall of the L-shaped plate, and an L-shaped block is fixedly connected to the right outer wall of the concave block, the outer wall of the L-shaped block being slidably connected inside the fixed block.

[0013] Preferably, a second spring is fixedly connected to the left outer wall of the concave block, and the outer wall of the second spring is fixedly connected to the inside of the fixed block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the base can be installed or disassembled without tools through the cooperation between the U-shaped rod, hollow block, slider, spring, transmission plate, support shaft and limit block, making the operation more convenient. When the base is worn or damaged, only the base needs to be replaced instead of the entire air cushion, which reduces the maintenance cost during use. At the same time, the replaceable base makes it easier to improve the ground adaptability of the air cushion.

[0015] 2. In this utility model, the L-shaped plate is limited or released by the cooperation between the L-shaped plate, the fixing block, the concave block, the spring, and the L-shaped block, which facilitates the locking or release of the connecting pipe of the cap or the inflatable component. This effectively prevents gas leakage during the inflation or static placement of the air cushion, ensures the stability of the internal pressure of the air cushion, and improves the safety of the lifting process. At the same time, the sealing sleeve and sealing ring ensure the sealing between the connecting pipe of the cap or the inflatable component and the air inlet pipe. Attached Figure Description

[0018] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this utility model provides: a high-pressure lifting air cushion for rescue, including an air cushion body 1, an air inlet pipe 2 fixedly connected inside the air cushion body 1, a cap 3 provided on the outer wall of the air inlet pipe 2, a load-bearing plate 4 provided on the upper surface of the air cushion body 1, an installation ring 5 fixedly connected to the lower surface of the air cushion body 1, a base 6 provided inside the installation ring 5, a hollow block 8 fixedly connected inside the installation ring 5, a U-shaped rod 7 slidably connected inside both the installation ring 5 and the hollow block 8, a slider 9 fixedly connected to the outer wall of the U-shaped rod 7, a spring 10 fixedly connected to the outer wall of the slider 9, the outer wall of the spring 10 fixedly connected inside the hollow block 8, a transmission plate 11 slidably connected to the outer wall of the slider 9, a support shaft 12 rotatably connected inside the transmission plate 11, a limit block 13 slidably connected inside the transmission plate 11, the outer wall of the limit block 13 is provided inside the base 6, and a positioning component is provided on the lower surface of the installation ring 5; Specifically, the air inlet pipe 2 provides a high-pressure gas input channel for the air cushion body 1. The cap 3 is fitted over the outside of the air inlet pipe 2 to mechanically seal and protect the air inlet. The load-bearing plate 4 serves as the contact platform with the object being lifted, while the mounting ring 5 serves as the mounting base for the bottom limiting mechanism. The base 6 is the support base for the overall force of the air cushion. The load-bearing plate 4 and the base 6 form a top-to-bottom force-aligned structure, ensuring that no bias or tilting occurs during lifting. Short rods are provided on the side of the slider 9 and the limiting block 13 near the transmission plate 11. The short rods are arranged on the upper and lower sides of the transmission plate 11 and slide inside the transmission plate 11, so that the slider 9 and the limiting block 13 can move in opposite directions due to the rotation of the transmission plate 11. The spring force of the spring 10 provides support for the limiting block 13 inside the base 6. The above components make the installation and disassembly of the base 6 more convenient, and make it easier to replace different bases 6 according to the ground conditions of different rescue sites. A control valve is provided at the connection between the air cushion body 1 and the air inlet pipe 2. Since the control valve is a common control component on the market, it will not be described in detail.

[0020] Reference Figure 2 The positioning assembly includes a positioning rod 14, the top end of which is fixedly connected to the lower surface of the mounting ring 5, and the bottom end of which is located inside the base 6. Specifically, the positioning rod 14 facilitates the positioning of the base 6 during installation and limits its movement after installation to prevent accidental displacement.

[0021] Reference Figure 2 and Figure 3 The outer wall of the slider 9 is slidably connected to the inside of the hollow block 8, both ends of the support shaft 12 are fixedly connected to the inside of the hollow block 8, and the outer wall of the limiting block 13 is slidably connected to the inside of the hollow block 8 and the mounting ring 5. Specifically, the movement of the slider 9 is offset and restricted by the interior of the hollow block 8, and the support shaft 12 is fixed, thereby supporting the connection structure of the support shaft 12. The movement of the limit block 13 is also offset and restricted by the interior of the hollow block 8.

[0022] Reference Figure 4 Handles 16 are fixedly connected to both sides of the air cushion body 1, and a connecting plate 15 is provided on the upper surface of the load-bearing plate 4. The connecting plate 15 matches the base 6. Specifically, the handle 16 allows users to easily move the air cushion by simply holding the handles 16 on both sides. The connecting plate 15 has a groove inside, and the lower surface of the base 6 has a connecting rod that matches the groove, making it easy to connect other air cushions to the upper side of the connecting plate 15 or the lower side of the base 6 for stacking.

[0023] Reference Figure 5 and Figure 6 The cap 3 has a sealing sleeve 17 inside, which is fixedly connected to the outer wall of the air intake pipe 2. A sealing ring 18 is provided between the cap 3 and the sealing ring 18. An L-shaped plate 19 is fixedly connected to the outer wall of the cap 3. A fixing block 20 is slidably connected to the outer wall of the L-shaped plate 19. The outer wall of the fixing block 20 is fixedly connected to the outer wall of the air intake pipe 2. A concave block 21 is slidably connected inside the fixing block 20. The concave block 21 is located inside the outer wall of the L-shaped plate 19. An L-shaped block 23 is fixedly connected to the right outer wall of the concave block 21. The outer wall of the L-shaped block 23 is slidably connected to the inside of the fixing block 20. A spring 22 is fixedly connected to the left outer wall of the concave block 21. The outer wall of the spring 22 is fixedly connected to the inside of the fixing block 20. Specifically, the cap 3 has a groove inside, and the inner side of the sealing sleeve 17 is conical and angled towards the cap 3. This allows the outer wall of the sealing sleeve 17 to slide into the groove of the cap 3 when the cap 3 slides towards the air intake pipe 2. The sealing sleeve 17 is arranged in two layers, with a conical inner side and a circular outer side. A sealing ring 18 is fixed between the two layers. The sealing ring 18 is made of rubber, which allows it to deform under external force, thereby reducing the gap between the cap 3 and the air intake pipe 2. The cap 3 is positioned by the fixing block 20 and the L-shaped plate 19. The fixing block 20 supports and restricts the movement of the concave block 21 and the L-shaped block 23. The elastic force of the spring 22 provides power for the concave block 21 to limit the L-shaped plate 19. When the L-shaped plate 19 needs to be pulled out, the L-shaped block 23 can be pushed.

[0024] Working principle: When using this lifting air cushion, remove the cap 3 and connect the air inlet pipe 2 to the inflation component to inflate the air cushion body 1, thereby expanding the air cushion body 1. The expansion of the air cushion body 1 is supported by the mounting ring 5 and the base 6. The load-bearing plate 4 and the connecting plate 15 move upward as the air cushion body 1 expands, thereby lifting the object contacted by the connecting plate 15. By pressing the U-shaped rod 7, the slider 9 moves towards the center of the mounting ring 5 inside the hollow block 8, compressing the spring 10. The short rod on the outer wall of the slider 9 slides inside the transmission plate 11, causing the transmission plate 11 to rotate under the limit of the support shaft 12. The short rod on the outer wall of the limiting block 13 also slides inside the transmission plate 11, causing the limiting block 13 to move in the opposite direction to the U-shaped rod 7. The limiting block 13 slides out of the interior of the base 6, no longer limiting the base 6. The base 6 can be installed and disassembled without additional tools, making it convenient for maintenance or replacement of the base 6. L-shaped plates 19 are provided on the connecting pipes of the cap 3 or the inflatable component, and a groove is provided on the side near the fixing block 20 to match the outer wall of the sealing sleeve 17. This allows the cap 3 or the connecting pipe of the inflatable component to be slid directly to the air inlet pipe 2. The sealing sleeve 17 and the sealing ring 18 seal the connection between the cap 3 or the inflatable component and the air inlet pipe 2. At the same time, the L-shaped plate 19 slides into the interior of the fixing block 20. The inclined surface of the L-shaped plate 19 pushes the concave block 21 to move, which compresses the second spring 22. After the L-shaped plate 19 moves to the appropriate position, the elastic force of the second spring 22 causes the concave block 21 to lock the L-shaped plate 19, thereby achieving locking when the cap 3 or the inflatable component is connected to the air inlet pipe 2.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
