Description

Technical Field

[0001] This utility model relates to a rescue air cushion, and more particularly to a rapid inflation docking device for a rescue air cushion. Background Technology

[0002] In scenarios such as fire rescue and high-altitude emergency rescue, rescue air cushions are key equipment to ensure the safety of trapped personnel. Their rapid inflation capability is directly related to rescue efficiency and personnel safety. Especially in emergency situations such as fires and falls from heights, rescuers need to deploy and inflate the rescue air cushion in a very short time to form a safe buffer zone. At this time, the rapid and stable connection between the air pump and the air cushion inflation interface becomes the core link affecting the progress of the rescue.

[0003] With existing technology, docking usually requires manual fixing of the air pump and the connecting pipe, which is not only slow but also increases the complexity of operation and delays rescue time. In addition, the air pressure output by the air pump at the moment of inflation is relatively large. Traditional docking structures lack a reliable locking mechanism, which can easily cause the air pump and the connecting pipe to suddenly separate due to the instantaneous high pressure. This will not only interrupt the inflation process but may also cause secondary safety risks due to the detachment of parts, seriously affecting rescue efficiency and safety. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid inflation docking device for rescue air cushions, which can achieve rapid locking and stable connection between the air pump and the docking pipe, solving the problems of slow speed and easy separation in traditional docking methods.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rapid inflation docking device for rescue air cushions is provided, comprising a docking tube. The outer wall of the docking tube has multiple grooves, and the interior of each groove has a telescopic groove. A locking block is provided inside each telescopic groove. A protrusion is fixedly connected to the end of the locking block away from the docking tube. Two springs are fixedly connected to the outer wall of the protrusion facing the telescopic groove. Two spring grooves are provided inside each groove. One end of each spring is fixedly connected to the inner wall of the spring groove. A movable component is fitted onto the outer wall of the docking tube. The movable component includes a movable ring. The inner wall of the movable ring has a threaded opening and an annular opening. The threaded opening is threadedly connected to the outer wall of the docking tube. An insertion port is provided at one end of the docking tube. An air pump is provided on the right side of the docking tube. An insertion tube is fixedly connected to the air delivery end of the air pump. The insertion tube is located inside the insertion port. A locking groove is provided on the outer wall of the insertion tube, and the locking block extends from the end inside the docking tube into the locking groove. Optionally, the groove and the telescopic groove are arranged perpendicularly to each other, the protrusion and the locking block are arranged perpendicularly, the cross-section of the locking block and the locking groove is triangular, the inner wall of the annular opening is inclined, and the inner wall of the annular opening is tightly fitted with the top of the protrusion.

[0006] Optionally, the outer wall of the insertion tube is fixedly connected with a limiting strip, and there are multiple limiting strips. The inner wall of the insertion port is provided with a limiting groove, and there are multiple limiting grooves. The limiting strip is located inside the corresponding limiting groove.

[0007] Optionally, a sealing gasket is installed inside the socket, and the sealing gasket is located between the insert and the left inner wall of the socket.

[0008] Optionally, a positioning ring is fixedly connected to the outer wall of the connecting pipe, the outer diameter of the left end of the connecting pipe is smaller than the outer diameter of the right end, and the positioning ring is located on the outer wall of the right end of the connecting pipe.

[0009] Optionally, the outer wall of the movable ring is provided with anti-slip texture, and the positioning ring is located on the left side of the movable ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves a rapid locking function for the air pump tube by setting a groove, telescopic groove, and locking block structure on the outer wall of the connecting pipe, in conjunction with the threaded drive mechanism of the moving ring. When the moving ring rotates and moves, the inclined surface of its inner wall squeezes the protrusion, causing the locking block to telescopically move, so that the triangular locking block is accurately locked into the locking groove of the tube. This not only greatly shortens the docking time, but also ensures a stable connection during inflation through the mechanical self-locking structure, solving the problem of easy separation in traditional manual docking, and significantly improving rescue efficiency and safety. The combination of the limiting strip and the limiting groove further ensures the accuracy of docking and the anti-torsion ability.

[0011] 2. This utility model achieves complete sealing of the inflation channel by setting a sealing gasket structure inside the connector, preventing high-pressure gas leakage. The positioning ring on the right end of the connector and the small outer diameter design on the left end cooperate to ensure the correct stroke positioning of the moving ring and facilitate quick alignment and installation. The anti-slip texture design on the outer wall of the moving ring plays an anti-slip role, enabling rescuers to quickly complete the docking operation in emergency situations.

[0019] Reference Figure 1-7 The present invention provides a quick-inflation docking device for a rescue air cushion. The device includes a docking tube 1. The outer wall of the docking tube 1 has multiple grooves 3, which are arranged perpendicularly to each other and to telescopic grooves 2. Telescopic grooves 2 are formed inside the multiple grooves 3. Locking blocks 4 are provided inside the telescopic grooves 2. A protrusion 5 is fixedly connected to the end of the locking block 4 away from the docking tube 1. The protrusion 5 is arranged perpendicularly to the locking block 4. Two springs 6 are fixedly connected to the outer wall of the protrusion 5 facing the telescopic groove 2. Spring grooves 7 are formed inside the grooves 3, and two spring grooves 7 are provided. One end of each spring 6 is fixedly connected to the inner wall of the spring groove 7. A moving component 8 is fitted onto the outer wall of the docking tube 1. The moving component 8 includes a moving ring 801. The inner wall of the moving ring 801 has a threaded opening 802 and an annular opening 803. The inner wall of the port 803 is inclined, and the inner wall of the annular port 803 fits tightly with the top of the protrusion 5. The threaded port 802 is threadedly connected to the outer wall of the connecting pipe 1. One end of the connecting pipe 1 is provided with a socket 9. An air pump 10 is provided on the right side of the connecting pipe 1. The air supply end of the air pump 10 is fixedly connected to a tube 11. The tube 11 is located inside the socket 9. The outer wall of the tube 11 is provided with a locking groove 12, and there are multiple locking grooves 12. The cross-section of the locking block 4 and the locking groove 12 is triangular. The end of the locking block 4 located inside the connecting pipe 1 extends into the interior of the locking groove 12. The outer wall of the tube 11 is fixedly connected with a limiting strip 13, and there are multiple limiting strips 13. The inner wall of the socket 9 is provided with a limiting groove 14, and there are multiple limiting grooves 14. The limiting strip 13 is located inside the corresponding limiting groove 14.

[0020] In use, insert the tube 11 of the air pump 10 into the inlet 9 of the connecting tube 1. The limiting strip 13 and the limiting groove 14 work together to ensure precise alignment. Then, rotate the moving ring 801 to move it to the right. The inclined surface of its annular opening 803 presses against the protrusion 5, causing the locking block 4 to overcome the elastic force of the spring 6 and retract into the telescopic groove 2 and lock into the locking groove 12 of the tube 11. At this time, the spring 6 is in a compressed state, and the triangular cross-section locking block 4 and the locking groove 12 are tightly engaged to form a stable connection. The sealing gasket 15 ensures airtightness. During inflation, this locking structure can resist the impact of high-pressure airflow. When separation is required, rotate the moving ring 801 in the opposite direction to move it to the left. The moving ring 801 releases the pressure on the protrusion 5, the spring 6 rebounds, and pushes the locking block 4 to disengage from the locking groove 12, allowing the tube 11 to be pulled out. The positioning ring 16 is used to limit the movement of the moving ring 801. The anti-slip texture design provides anti-slip function and facilitates operation. The entire mechanism achieves fast and reliable docking and separation.

[0021] In another embodiment of this utility model, please refer to Figure 7 A sealing gasket 15 is installed inside the socket 9. The sealing gasket 15 is located between the insertion tube 11 and the left inner wall of the socket 9, which realizes the complete sealing of the inflation channel and prevents high-pressure gas leakage.

[0022] In another embodiment of this utility model, please refer to Figure 1 A positioning ring 16 is fixedly connected to the outer wall of the connecting pipe 1. The outer diameter of the left end of the connecting pipe 1 is smaller than that of the right end. The positioning ring 16 is located on the outer wall of the right end of the connecting pipe 1, which ensures the correct stroke positioning of the moving ring 801.

[0023] In another embodiment of this utility model, please refer to Figure 1 The outer wall of the moving ring 801 is provided with anti-slip texture, and the positioning ring 16 is located on the left side of the moving ring 801.
