At this time, the container can be inspected by the testing mechanism 4 and the support mechanism 3. At the same time, by detecting multiple positions, the accuracy of the container can be improved, thereby improving the detection effect of the device.

[0028] Specifically, two first protective doors 9 are rotatably connected to the surface of the protective shell 6, and a first handle 10 is installed on the surface of the first protective door 9.

At the same time, the setting of the first handle 10 and the second handle 12 facilitates the movement of the first protective door 9 and the second protective door 11.

[0030] Specifically, the supporting mechanism 3 includes a movable pallet 301 installed on the surface of the movable block of the movable electric cylinder 2, a test lower shell 302 is installed on the surface of the movable pallet 301, a first folding plate 303 is installed on the surface of the movable pallet 301, a second buffer 304 is installed on the surface of the first folding plate 303, a second folding plate 305 is installed on the surface of the movable pallet 301, a third buffer 306 is installed on the surface of the second folding plate 305, a first electric telescopic rod 307 is installed on the surface of the movable pallet 301, and a first pressure sensor 308 is installed on the surface of the extended end of the first electric telescopic rod 307.

[0032] Specifically, two limiting rails 13 are installed on the surface of the movable electric cylinder 2 , and the movable support plate 301 is slidably connected to the surfaces of the limiting rails 13 .

[0033] In a specific embodiment of the present invention, the positioning rail 13 is provided to increase the stability of the movable support plate 301 during movement, while reducing the probability of the test lower shell 302 being offset due to movement.

[0034] Specifically, a plurality of first buffers 14 are installed on the surface of the movable electric cylinder 2 , and a buffer plate 15 adapted to the first buffers 14 is installed on the bottom of the movable support plate 301 .

[0035] In a specific embodiment of the present invention, through the coordinated use of the first buffer 14 and the buffer plate 15, the movable pallet 301 drives the buffer plate 15 to move when it moves. At this time, the first buffer 14 can block the buffer plate 15, thereby reducing the probability of the movable pallet 301 falling from the surface of the limit rail 13.

[0036] Specifically, the testing mechanism 4 includes a fixed plate 401 installed on the surface of the mounting base 1, a second electric telescopic rod 402 is installed on the surface of the fixed plate 401, a test tray 403 is installed on the surface of the extended end of the second electric telescopic rod 402, a plurality of second pressure sensors 404 are installed at the bottom of the test tray 403, a test upper shell 405 adapted to the test lower shell 302 is installed at the bottom of the second pressure sensor 404, and the detection head of the second pressure sensor 404 extends to the interior of the test upper shell 405, a boosting pump 406 is installed on the surface of the test upper shell 405, a pressure relief valve 407 is installed on the surface of the test upper shell 405, a plurality of reinforcement rods 408 are installed at the bottom of the fixed plate 401, and the reinforcement rods 408 are fixedly connected to the surface of the movable electric cylinder 2.

[0037] In a specific embodiment of the present utility model, when the second electric telescopic rod 402 is started, it drives the test tray 403, the second pressure sensor 404 and the test upper shell 405 to move, and then closes the test upper shell 405 and the test lower shell 302. At this time, multiple second pressure sensors 404 will record the pressure inside the test upper shell 405 and the test lower shell 302, and then increase the pressure inside through the booster pump 406. After the pressure is increased, it will remain stationary for a period of time. The pressure condition and air tightness of the container can be checked through the values detected by the second pressure sensor 404.

[0038] Specifically, the controller 5 is electrically connected to the control button 7 , the movable electric cylinder 2 , the second electric telescopic rod 402 , the second pressure sensor 404 , the booster pump 406 and the pressure relief valve 407 , respectively.

[0040] Working principle: The container can be placed through the test lower shell 302, and the second buffer 304 and the third buffer 306 can assist the test upper shell 405 to align with the test lower shell 302, and then the pressure inside the test lower shell 302 can be detected through the first pressure sensor 308. Then, the support mechanism 3 is moved to the bottom of the test mechanism 4 by moving the electric cylinder 2. When the second electric telescopic rod 402 is started, it drives the test tray 403, the second pressure sensor 404 and the test upper shell 405 to move, and then the test upper shell 405 and the test lower shell 302 are closed. At this time, multiple second pressure sensors 404 will record the pressure inside the test upper shell 405 and the test lower shell 302, and then the internal pressure is increased by the booster pump 406. After the pressure is increased, it is kept still for a period of time. The pressure condition and airtightness of the container can be checked through the value detected by the second pressure sensor 404. At the same time, the position detection of multiple second pressure sensors 404 can improve the accuracy of the container, thereby improving the detection effect of the device.
