[0024] 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.

[0025] According to an embodiment of the present invention, a device for detecting the sealing performance of a shock-absorbing rubber airbag is provided. Example

[0026] like Figures 1-4As shown, the shock-absorbing rubber airbag sealing performance testing device according to an embodiment of the present invention includes a workbench 1, a placement groove 2 inside the workbench 1, an air pump 3 inside the placement groove 2, an output end of the air pump 3 connected to an air supply pipe 4, a pressure regulating valve 5 on the air supply pipe 4, one end of the air supply pipe 4 rotatably connected to a connector 6, a first pressure sensor 7 and a solenoid valve on the air supply pipe 4, the first pressure sensor 7 being electrically connected to a processor 8, the processor 8 being located inside the placement groove 2, an opening 9 on the workbench 1, one end of the air supply pipe 4 being placed inside the opening 9, a support frame 10 above the workbench 1, and an electric extension device at the top of the support frame 10. Telescopic rod 11 is electrically connected to processor 8. The bottom end of the telescopic rod 11 is connected to pressure plate 12. Connector 6 has clamping plates 13 on both sides. The opening 9 has a slot 14 inside, and the clamping plates 13 and slots 14 match. The bottom end of pressure plate 12 has a second pressure sensor 15, which is electrically connected to processor 8. An alarm 16 is located above processor 8 and is electrically connected to processor 8. A control switch 27 is located on one side of workbench 1 for controlling the electrical components of the device. Casters 28 are connected to the bottom end of workbench 1 for easy adjustment of the position of workbench 1. Using the above scheme, when testing the sealing performance of the shock-absorbing rubber airbag, the connector 6 is connected to the airbag, and the airbag is placed on the workbench 1. The air pump 3 is activated, supplying gas to the airbag through the air supply pipe 4. A pressure regulating valve 5 is installed on the air supply pipe 4 to precisely control the gas pressure entering the airbag. Simultaneously, a first pressure sensor 7 is equipped to monitor the pressure changes inside the airbag in real time and transmit the data to the processor 8. When inflation is complete, the solenoid valves on the air pump 3 and air supply pipe 4 are closed, and the electric telescopic rod 11 is activated, causing the pressure plate 12 to press down, bringing it into contact with the airbag. During the pressing process, a second pressure sensor 15 detects the pressure applied to the airbag to prevent excessive pressure. During the pressing phase, the processor 8 continuously receives data from the first pressure sensor 7 and the second pressure sensor 15 and processes and analyzes it. When the pressure plate 12 reaches a predetermined value, the processor 8 issues a command to stop the pressing action of the electric telescopic rod 11. This ensures that the pressure applied to the airbag does not exceed a safe range, preventing damage. Simultaneously, the processor 8 records the current pressure value and compares it to a preset value to determine if the airbag's sealing performance meets requirements. If the value recorded by the first pressure sensor 7 exceeds the expected range, it indicates a leak or poor sealing performance in the airbag. In this case, the processor 8 can trigger the alarm 16 to sound an alarm, alerting personnel to take action. When the value from the first pressure sensor 7 falls within the expected range, the processor 8 will control the electric telescopic rod 11 to automatically move upwards, facilitating the inspection of the next airbag.

[0027] like Figures 1-4As shown, a fixed plate 17 is provided on one side of the support frame 10. The fixed plate 17 has a threaded hole 18 inside, and a threaded rod 19 is threadedly connected inside the threaded hole 18. One end of the threaded rod 19 is connected to the display screen 20 through a bearing. The display screen 20 is electrically connected to the processor 8. A driven gear 21 is fixedly connected to the threaded rod 19. One side of the driven gear 21 meshes with the driving gear 22. The driving gear 22 is connected to the output end of the servo motor 23 through a rotating shaft. The servo motor 23 is mounted on a fixed block 24. One side of the fixed block 24 is connected to a limiting plate 25, and the other side is fixedly connected to the display screen 20. A limiting groove 26 is provided on the fixed plate 17. The limiting plate 25 matches the limiting groove 26 to prevent rotation during the movement of the display screen 20. Through the above scheme, during the testing process, operators can observe the values ​​of the first pressure sensor 7 and the second pressure sensor 15 on the display screen 20. By activating the servo motor 23, the drive gear 22 can be rotated. The rotation of the drive gear 22 drives the driven gear 21 and the threaded rod 19 to rotate. The rotation of the threaded rod 19 allows it to move within the threaded hole 18, adjusting the height of the display screen 20. Operators can flexibly adjust the height of the display screen 20 according to their height and viewing angle, ensuring clear observation of the data on the display screen 20 under any circumstances. This reduces operator fatigue and improves the accuracy and reliability of the testing work.

[0028] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting a pressure regulating valve 5 and a first pressure sensor 7 on the gas supply pipe 4, the gas pressure entering the airbag under test can be precisely controlled, and the pressure changes inside the airbag can be monitored in real time. This design ensures the consistency and accuracy of each test condition, greatly improving the reliability of the test results. Furthermore, by setting an electric telescopic rod 11 and a pressure plate 12, the load conditions in actual applications can be simulated, allowing for a more realistic evaluation of the airbag's sealing performance under pressure. Additionally, by connecting the display screen 20 via a threaded rod 19 and using a servo motor 23 to drive the driven gear 21 system, the height of the display screen 20 can be automatically adjusted, facilitating observation of test results by personnel of different heights and improving the ease of use and comfort of the equipment.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
