The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model. Embodiment 1

[0025] A high-pressure resistant valve core testing device, as Figures 1-4 shown, includes a pressure resistance testing component. The pressure resistance testing component includes a workbench 1. A protective frame 15 is fixedly arranged on the outer wall of the top of the workbench 1 through bolts. An installation frame 17 is fixedly arranged on one side of the protective frame 15 through bolts. An installation shaft 19 is installed through the installation frame 17. A protective door 16 is rotatably installed through the installation shaft 19. The protective door 16 is adapted to the protective frame 15. An inflatable cavity 20 is arranged on the top of the workbench 1. The position of the inflatable cavity 20 is adapted to the protective frame 15. A pressure sensor 23 is arranged on the inner wall of the inflatable cavity 20. An air nozzle 21 is connected to the top of the inflatable cavity 20. An air pump 18 is fixedly arranged on the outer wall of one side of the protective frame 15 through bolts. One end of the air pump 18 is connected with a connector 22. One end of the connector 22 is connected into the protective frame 15. An appearance detection component for performing appearance detection is arranged on one side of the workbench 1;

[0026] During use, after taking out the test sample from the processed valve core, it is installed on the air nozzle 21. The trachea is connected through the connector 22. One end of the trachea is connected to the air nozzle 21, and inflation is started through the air pump 18. The air pressure value can be monitored through the pressure sensor 23. After the air pressure value rises to a certain value, the trachea is disconnected. Whether there is air leakage can be checked by monitoring the pressure. After completion, it is tested whether it can deflate normally to complete the detection of the pressure resistance and function of the valve core. The high-pressure environment in actual use can be simulated to detect whether there is air leakage. At the same time, it can be tested whether it can inflate and deflate normally. After comprehensive detection, it can be tested whether the function of the valve core is normal, avoiding defective valve cores from flowing into the market and affecting product quality. Closing the protective door 16 to enclose the protective frame 15 can increase safety during testing, and it can avoid the situation that the inflation cavity 20 cracks due to excessive pressure and debris splashes and injures the tester or the valve core flies out due to improper installation;

[0027] The appearance detection component includes an electric lifting rod 7. The electric lifting rod 7 is fixed to the outer wall of the top of the workbench 1 by bolts. A placement tray 8 is installed at the top of the electric lifting rod 7. A support frame 9 is installed on the top of the workbench 1. A camera 10 is installed on one side of the support frame 9. The camera 10 is adapted to the placement tray 8;

[0028] During use, the valve core to be detected is placed in the placement tray 8. The valve core is photographed through the camera 10. The photographed image is enlarged to align for appearance detection. Whether there are cracks or other defects can be checked. The electric lifting rod 7 can drive the placement tray 8 to move to make the valve core closer to the camera 10, so that the photographing is clearer and the local observation is more detailed;

[0029] For supporting the device, as Figure 1 shown, support legs 2 are fixedly arranged on the outer wall of the bottom of the workbench 1 by bolts. There are multiple groups of support legs 2. Foot pads 3 are arranged at the bottom of the support legs 2;

[0030] During use, the device can be supported by the cooperation of the support legs 2 and the foot pads 3, and the stability of the device during use can be maintained;

[0031] To prevent the accidental opening of the protective door 16, as Figure 1 、 4 shown, a fixed block 12 is fixedly arranged on the outer wall of one side of the protective frame 15 by bolts. A fixed shaft 13 is installed on one side of the fixed block 12. A limit frame 14 is rotatably installed through the fixed shaft 13. The limit frame 14 is adapted to the protective door 16;

[0032] During use, after closing the protective door 16, by rotating the limit frame 14 so that one end thereof fits against the protective door 16, the protective door 16 can be clamped to limit it, avoiding the accidental opening of the protective door 16 during use. There is a certain damping between the limit frame 14 and the fixed shaft 13, which can prevent the limit frame 14 from rotating without being touched.

[0033] For the convenience of observation during testing, as Figure 1 shown, both the protective frame 15 and the protective door 16 are made of transparent materials.

[0034] During use, the protective frame 15 and the protective door 16 made of transparent materials can facilitate the observation of the internal situation without opening the protective door 16 during the testing process.

[0035] For the convenience of control, as Figure 1 shown, a fixed bracket 5 is fixedly arranged on the outer wall of the top of the workbench 1 through bolts, and a control panel 6 is installed on one side of the fixed bracket 5.

[0036] During use, the control panel 6 is connected to each component of the device through wires. Through the control panel 6, each component can be conveniently controlled. At the same time, the current test pressure value can be displayed for recording, and the captured image can also be displayed for viewing.

[0037] To prevent the device from sliding and displacing, as Figure 2 shown, an anti-slip pad 4 is provided at the bottom of the foot pad 3, and the anti-slip pad 4 is made of rubber material.

[0038] During use, the rubber anti-slip pad 4 can increase the friction when contacting the ground, thereby preventing the device from having unnecessary sliding and displacement. Embodiment 2

[0039] To increase lighting, referring to Figure 2 、 3 , for a high-pressure resistant valve core testing device, the following improvements are made in this embodiment compared with Embodiment 1. A lighting lamp 11 is provided on one side of the support frame 9.
