[0021] It is necessary to point out here that the following specific embodiments are only used to further illustrate the application, and cannot be understood as limiting the protection scope of the application, and the skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0022] Example 1

[0023] As Figure 1 - Figure 3 As shown in the accompanying drawings, an aviation cleaning bag sealing degree detection structure comprises a vacuum sealing inspection instrument 1 and a detection barrel 2 arranged on the vacuum sealing inspection instrument 1, wherein the detection barrel 2 is provided with a barrel cover 3.

[0024] Further comprising:

[0025] A pressing plate 5 is slidingly arranged on the barrel cover 3.

[0026] A pressure sensor 6 is arranged at the bottom of the detection barrel 2, and the aviation cleaning bag is pressed by the pressing plate 5, so as to indirectly press the pressure sensor 6.

[0027] A sealing gasket 31 is arranged at the bottom edge of the barrel cover 3, and the barrel cover 3 is connected with the detection barrel 2 through the sealing gasket 31. A screw rod 4 is rotatably arranged on the barrel cover 3, and the detection barrel 2 serves as a bearing main body for detection and provides a stable detection space for the aviation cleaning bag. The structure design cooperates with the barrel cover 3 to effectively create a relatively independent and controllable pressure detection environment.

[0028] A sealing shaft 41 is arranged on the screw rod 4, which ensures that the screw rod 4 can be effectively rotatably arranged on the barrel cover 3 under the premise of ensuring the sealing of the detection barrel 2. The sealing shaft 41 is arranged on the barrel cover 3, and the screw rod 4 is provided with a sliding rod 42 on both sides.

[0029] A threaded cylinder 51 is arranged on the pressing plate 5, which is threadedly connected with the screw rod 4. The threaded cylinder 51 is provided with a sleeve 52 on both sides, which is sleeved on the sliding rod 42, so that the pressing plate 5 can stably slide on the barrel cover 3 to realize the pressing operation of the aviation cleaning bag. A plurality of holes are arrayed on the pressing plate 5, so that the air in the detection barrel 2 can flow quickly.

[0030] A gas pipe 11 is arranged on the vacuum sealing inspection instrument 1, and the other end of the gas pipe 11 is connected with the barrel cover 3. The vacuum sealing inspection instrument 1 serves as a core power source, and is connected with the barrel cover 3 through the gas pipe 11, so as to quickly and efficiently vacuum the inside of the detection barrel 2, to provide necessary conditions for detecting the sealing performance of the aviation cleaning bag in a low-pressure environment, and to be a key power support component for the operation of the entire detection structure.

[0031] It should be noted that the working principle of the aviation cleaning bag sealing degree detection structure is as follows: first, the aviation cleaning bag to be detected is sealed at both ends under the premise of being filled with air, and then it is placed in the detection barrel 2, the barrel cover 3 on the detection barrel 2 is tightly connected with the detection barrel 2 through the sealing gasket 31 at the bottom edge, so as to ensure the sealing of the detection environment. The vacuum sealing tester 1 is connected with the barrel cover 3 through the air pipe 11, and the inside of the detection barrel 2 can be vacuumized. The screw rod 4 is rotatably arranged on the barrel cover 3, and the slide rods 42 on both sides of the screw rod 4 serve as a guide. The threaded cylinder 51 on the pressing plate 5 is threadedly connected with the screw rod 4, the sleeve 52 is sleeved on the slide rod 42, and when the screw rod 4 is rotated, the pressing plate 5 can slide up and down on the barrel cover 3. Before detection, the screw rod 4 is rotated to make the pressing plate 5 descend, and the aviation cleaning bag is pressed. The multiple holes arranged on the pressing plate 5 are helpful to uniform force. During the pressing process, the pressure of the aviation cleaning bag is indirectly transmitted to the pressure sensor 6 at the bottom of the detection barrel 2, and the pressure data on the pressure sensor 6 is obtained. After the detection barrel 2 is vacuumized by the vacuum sealing tester 1, as the air pressure in the detection barrel 2 decreases, if the cleaning bag is sealed well, the cleaning bag sealed at both ends will be inflated, and the inflated cleaning bag will immediately generate pressure change to the pressure sensor 6 below, so as to make the pressure sensor 6 quickly respond. Compared with the traditional method, this detection method can obtain detection feedback in a very short time, the response speed is very fast, and the detection efficiency is greatly improved. At the same time, water can still be injected in the detection barrel 2, and the traditional water detection can be used. When the water detection method is used, the adjustable pressing plate 5 does not need to inject a large amount of water in the detection barrel 2, and the pressing plate 5 can realize effective pressing.

[0032] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
