[0016] In order to better understand the above objects, features and advantages of the present utility model, the following will further illustrate the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0018] Embodiment 1, as Figure 1 shown, a cartridge vial seal non-destructive testing device includes a test chamber 1, a test bottom chamber 2 is arranged inside the test chamber 1, a test top chamber 3 is arranged above the test bottom chamber 2, a positioning cover 4 is arranged inside the test top chamber 3, a cartridge vial sleeve 5 is arranged on one side of the positioning cover 4, a vacuum hole 6 is arranged on one side of the cartridge vial sleeve 5, a sealing ring 7 is arranged on one side of the vacuum hole 6, and a positioning pad 8 is arranged inside the cartridge vial sleeve 5.

[0019] The test chamber 1 is divided into two parts, namely, the test bottom chamber 2 and the test top chamber 3. The test chamber 1 is made of high-strength, corrosion-resistant materials, so as to ensure the stability of the air pressure inside and outside the test chamber 1 under high negative pressure conditions. The test chamber 1 is also the core part of the device, and a high-precision pressure sensor is arranged inside it, so as to cooperate with the device to detect the pressure changes inside it. A positioning cover 4 is arranged inside the test top chamber 3, and the positioning cover 4 can fix the cartridge bottle in the sleeve in the detection device to ensure that the bottle body will not move or displace during the test. This helps to improve the accuracy and consistency of the detection and avoid false positive misjudgment caused by the unstable position of the cartridge bottle. A cartridge bottle sleeve 5 is arranged on one side of the positioning cover 4. The cartridge bottle sleeve 5 is a replaceable modular structure, and cartridge bottle sleeves 5 of different specifications can be replaced according to the different sizes of the cartridge bottle. In this way, only one cavity can adapt to cartridge bottles of different sizes to prevent leakage during the test. In addition, the inner wall of the cartridge bottle sleeve 5 is smooth and has a certain elasticity to ensure a good seal with the cartridge bottle, thereby increasing the accuracy of the test.

[0020] A vacuum hole 6 is provided on one side of the cartridge sleeve 5, and a sealing ring 7 is provided on one side of the vacuum hole 6. The vacuum hole 6 is used to connect a vacuum pump to establish a vacuum environment inside the detection chamber by extracting the gas inside the cartridge sleeve 5. The vacuum degree can be adjusted and monitored through the vacuum hole 6 to ensure that the negative pressure required during the detection process reaches a predetermined value. After the test is completed, the vacuum hole 6 can be used to discharge the vacuum environment in the detection chamber and restore the normal air pressure. This process usually involves releasing the control of the vacuum pump to facilitate subsequent operations and retesting. The main function of the sealing ring 7 is to ensure the sealing between the vacuum hole 6 and the cartridge sleeve 5. During the detection process, the sealing ring 7 can prevent air or gas from leaking through the contact surface, thereby maintaining the vacuum state inside the detection chamber. A self-locking structure 11 is provided between the positioning cover 4 and the cartridge sleeve 5, and the self-locking structure 11 can help the positioning cover 4 to be sealed and connected with the test top chamber 3.

[0021] A positioning pad 8 is provided inside the cartridge bottle sleeve 5, and the positioning pad 8 is used to fix the position of the cartridge bottle to prevent displacement in a negative pressure environment. At the same time, the positioning pad 8 cooperates with the positioning cover 4 to fix the cartridge bottle, thereby increasing the accuracy of the test. A connector 9 is provided on one side of the test cavity 1, and the connector 9 is used to connect the test bottom cavity 2 and the test top cavity 3. Locking caps 10 are provided on the upper and lower sides of the test cavity 1. The number of locking caps 10 is 2, and a threaded structure is adopted, which is convenient for users to quickly install and disassemble, and can make the test bottom cavity 2 and the test top cavity 3 more tightly connected to prevent air leakage during testing.
