[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is equipped with an adjusting rod and a one-way valve. The pressure-resistant tank fixes the adjusting rod inside, and the adjusting rod is used to adjust the angle. After the adjustment is completed, the adjusting rod is fixed by the fastening nails inside the adjusting rod to ensure the stability of the adjusting rod, which is convenient for users to adjust the distance between the pressure sensor plate on the support plate according to needs, thereby improving the adaptability of the device.

The expansion of the sphere squeezes the pressure sensing plate, and the change in squeezing pressure is detected by the pressure sensing plate. When the sphere leaks, the squeezing pressure becomes smaller, so it is convenient to judge the sealing of the sphere. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The pressure tank 1 is fixed with the adjusting rod 2 on the inside, and the adjusting rod 2 is adjusted in angle. After the adjustment is completed, it is fixed by the fastening nail inside the adjusting rod 2 to ensure the stability of the adjusting rod 2, so that the user can adjust the distance of the pressure sensing plate 4 on the supporting plate 3 as needed, so that the pressure sensing plate 4 is against the outside of the sphere. Then the sealing cover 9 is installed on the inner side of the pressure tank 1 through the sealing 8 to ensure the sealing. Then the air pump 15 is operated to extract the air inside the duct 11, and the air inside the one-way valve 12 is extracted through the duct 11. The one-way valve allows air to only go out but not in, so that the inside of the pressure tank 1 is negative pressure. Since the inside of the pressure tank 1 is negative pressure, and the inside of the sphere is normal pressure, due to the difference in air pressure, the gas inside the sphere expands. Due to the expansion of the sphere, the pressure sensing plate 4 is squeezed. The change of the squeezing pressure is detected by the pressure sensing plate 4. When the sphere leaks, the squeezing pressure will become smaller, which is convenient for judging the sealing of the sphere.

[0025] The bottom of the vacuum pump 15 is installed with a bottom plate by bolts, and the bottom plate is installed at the bottom of the pressure tank 1;

[0026] The bottom plate fixes the vacuum pump 15 and the pressure tank 1 on the top to ensure the stability of the vacuum pump 15 and the pressure tank 1.

[0027] A sealing assembly is installed on the top of the pressure tank 1, and the sealing assembly includes a sealing cover 9 movably installed on the top of the pressure tank 1, a sealing ring 8 is installed on the bottom of the sealing cover 9, and the sealing ring 8 is against the top of the pressure tank 1, and a clamping plate 10 is installed on the outside of the sealing cover 9, and a groove is opened on one side of the clamping plate 10. A fixing plate 5 is installed on the outside of the pressure tank 1, and a pull rod 6 is movably connected to the inner side of the fixing plate 5 through a connecting shaft, and the pull rod 6 passes through the inner side of the groove, and a fastener 7 is installed on the outer side of the pull rod 6 through a thread, and the fastener 7 is against the inner side of the clamping plate 10;

[0028] The pressure tank 1 is movably assembled with the sealing cover 9 on the top, and the sealing performance of the device is improved by the sealing ring 8. The sealing cover 9 fixes the outer card plate 10 to ensure the stability of the card plate 10. The pressure tank 1 is fixed to the outer fixed plate 5, and the fixed plate 5 is connected to the inner pull rod 6. The pull rod 6 is against the groove of the card plate 10. Then the user puts the fastener 7 on the top of the card plate 10 and tightens it with the fastener 7 to ensure the tightness of the device and facilitate the user to control the opening and closing of the device.

[0029] A mounting frame 16 is installed on the top of the bottom plate, and the mounting frame 16 is located outside the air pump 15. A controller 17 is installed on the top of the mounting frame 16.

[0030] The mounting frame 16 fixes the controller 17 on the top, and the controller 17 controls the operation of the device.

[0031] Working principle: the pressure tank 1 fixes the adjusting rod 2 on the inside, and the adjusting rod 2 adjusts the angle. After the adjustment is completed, it is fixed by the fastening nail inside the adjusting rod 2 to ensure the stability of the adjusting rod 2, so that the user can adjust the distance of the pressure sensing plate 4 on the support plate 3 as needed, so that the pressure sensing plate 4 is against the outside of the sphere. Then the user puts the fastener 7 on the top of the card plate 10, and fastens it through the fastener 7 to ensure the tightness of the device, so that the user can control the opening and closing of the device. The air pump 15 runs to extract the air inside the conduit 11, and the air inside the one-way valve 12 is extracted through the conduit 11. The one-way valve allows air to only go out but not in, so that the inside of the pressure tank 1 is negative pressure. Since the inside of the pressure tank 1 is negative pressure, and the inside of the sphere is normal pressure, due to the difference in air pressure, the gas inside the sphere expands, and the expansion of the sphere squeezes the pressure sensing plate 4. The change in extrusion pressure is detected by the pressure sensing plate 4. When the sphere leaks, the extrusion pressure will become smaller, which is convenient for judging the sealing of the sphere.
