The right side of the installation pipe 5 is fixedly connected with the first docking pipe 6. The design of the first docking pipe 6 is to cooperate with the second docking pipe 8 to dock the installation pipe 5 and the pressure measuring device 7.

[0034] The right side of the pressure measuring device 7 is fixedly connected with the second docking pipe 8. The inside of the second docking pipe 8 is slidably connected to the outside of the first docking pipe 6. The outside of the first docking pipe 6 is fixedly connected with a fixing ring 9. The design of the fixing ring 9 is to facilitate cooperation with the connecting seat 10 and the clamping ring 11 to make the connection between the pressure measuring device 7 and the first docking pipe 6 more stable.

[0035] The right side of the pressure measuring device 7 is fixedly connected with a connecting seat 10. The design of the connecting seat 10 is to connect the clamping ring 11. The right side of the connecting seat 10 is fixedly connected with two clamping rings 11. The design of the clamping ring 11 is to engage with the fixing ring 9. The right side of the pressure measuring device 7 is fixedly connected with a first spring 12. The design of the first spring 12 is to push the pressing ring 13 to restrain the connecting seat 10, so that the clamping ring 11 and the fixing ring 9 are more firmly engaged.

[0036] The right side of the first spring 12 is fixedly connected with a pressing ring 13. The inside of the installation pipe 5 is provided with a sealing assembly for sealing the installation pipe 5. One end of the external connection pipe 1 is fixedly connected with a limiting piece 21. The design of the limiting piece 21 is to limit the external connection pipe 1. The outside of the external connection pipe 1 is fixedly connected with a docking port 22. The design of the docking port 22 is to facilitate external connection to a ventilator.

[0037] The first spring 12 is sleeved on the outside of the connecting seat 10. The design of the first spring 12 is to push the pressing ring 13 to restrain the connecting seat 10, so that the clamping ring 11 and the fixing ring 9 are more firmly engaged. The inside of the pressing ring 13 is slidably connected to the outside of the connecting seat 10. The design of the pressing ring 13 is to restrain the connecting seat 10.

[0038] The outside of the fixing ring 9 is slidably connected to the inside of the connecting seat 10. The design of the fixing ring 9 is to facilitate cooperation with the connecting seat 10 and the clamping ring 11 to make the connection between the pressure measuring device 7 and the first docking pipe 6 more stable. The inside of the two clamping rings 11 is in contact with the outside of the first docking pipe 6. The design of the clamping ring 11 is to engage with the fixing ring 9.

[0039] As Figures 1 to 3 and Figure 4 shown, the sealing assembly includes a ventilation groove 14 and a sealing block 15. The ventilation groove 14 is opened inside the installation pipe 5. The outside of the sealing block 15 is slidably connected to the inside of the ventilation groove 14. The design of the ventilation groove 14 is to facilitate gas to enter the inside of the second inflatable bag 4 through it. The right side of the sealing block 15 is fixedly connected with a second spring 16.

[0040] The sealing block 15 is designed to seal the placement tube 5 under the push of the spring 16. The spring 16 is arranged inside the ventilation groove 14. The spring 16 is designed to push the sealing block 15. The sealing block 15 is made of silicone. The sealing block 15 made of silicone is relatively soft, can fit the inside of the placement tube 5, and also has good sealing performance.

[0041] The front side of the pressure measuring device 7 is rotatably connected to a knob 17, and the knob 17 is designed to facilitate cooperation with a marker 18 to adjust the state of the pressure measuring device 7. The front side of the pressure measuring device 7 is fixedly connected to three markers 18, and the markers 18 correspond to the three options of closing, pressure measuring and constant pressure inflation respectively. The left side of the pressure measuring device 7 is fixedly connected to an air inlet 19, and the air inlet 19 is designed to facilitate the entry of air into the interior of the pressure measuring device 7. The top of the pressure measuring device 7 is fixedly connected to a display panel 20, and the display panel 20 is designed to display the pressure in the inflatable bag 24.

[0042] Working principle: When the portable airbag is working, the pressure measuring device 7 will detect the air pressure in the airbag 2 4. When the air pressure in the airbag 2 4 is insufficient, the pressure measuring device 7 will start its internal air pump, and send the air through the docking tube 2 8 and the docking tube 1 6, and then send it into the interior of the airbag 2 4 through the placement tube 5. The airbag 2 4 sends the air into the interior of the hose 3 through the hose 3. When the air pressure remains constant, the spring 2 16 will push the sealing block 15 to allow the sealing block 15 to seal the placement tube 5, thereby reducing the leakage of air in the airbag 2 4, so that the air pressure inside the airbag 2 4 remains constant, the time of constant air pressure is extended, and the maintenance device runs more smoothly.

[0043] When the pressure monitoring and maintaining device needs to be docked with the airbag, the docking tube 2 8 is re-docked with the new docking tube 1 6, and the clamping ring 11 and the connecting seat 10 are matched to clamp the fixing ring 9. At this time, release the hand that is pushing the pressure ring 13, and the spring 12 will push the spring 12, so that the spring 12 binds the connecting seat 10, so that the clamping ring 11 can be more firmly engaged with the fixing ring 9, and the pressure ring 13 is pushed by hand to prevent the pressure ring 13 from squeezing the connecting seat 10. At this time, the clamping ring 11 will not be tightly engaged with the fixing ring 9, so that the docking tube 1 6 and the docking tube 2 8 can be separated, and the pressure measuring device 7 and the placement tube 5 can be separated. By allowing the connecting seat 10 and the clamping ring 11 to clamp with the fixing ring 9 under the pressure of the pressure ring 13, the docking of the docking tube 1 6 and the docking tube 2 8 can be made more stable, avoiding falling off or movement during use, which affects the pressure maintenance and monitoring of the airbag.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
