[0028] Finally, the movable plate 104 has a protruding rod 115 , and the detection water tank 102 has a concave hole 116 . The protruding rod 115 is inserted into the concave hole 116 , so as to achieve the purpose of limiting the detection water tank 102 and the movable plate 104 .

[0029] When using the utility model, the corresponding bottle body 106 is selected according to the bottle cap 107 to be detected, and then the connecting block 111 is pushed into the fixing block 110 from top to bottom. When the connecting block 111 reaches the inner bottom of the fixing block 110, the through hole of the fixing block 110 will be aligned with the through hole of the connecting block 111.

At this time, the external air storage tank is connected to the three-way pipe 108, so that the air stored in the external air storage tank can be transmitted to the detection water tank 102 through the three-way pipe 108, so that the air pressure inside the detection water tank 102 rises, and then maintains the pressurized state, so that the bottle body 106 and the bottle cap 107 are completely submerged. The bottle cap 107 is kept underwater for 1-3 minutes, and the test results are observed at the end. During the pressurized time, whether bubbles are generated in the water or whether there is water in the bottle body 106 is detected to determine the leakage of the bottle cap 107, so as to detect the sealing of the bottle cap 107. When the air is transmitted to the detection water tank 102, the opening and closing degree of the three-way pipe 108 can be adjusted by the pressure adjustment display 109, so that the air pressure entering the detection water tank 102 can be adjusted, and at the same time, the air pressure in the detection water tank 102 can be displayed in real time.

[0032] Since the bottle bodies 106 of different sizes can be installed between the two fixing frames 105, the bottle caps 107 of different sizes can be installed between the two fixing frames 105, so as to detect the sealing performance of the bottle caps 107 of different sizes, thereby improving the application scope of the detection device and solving the technical problem that the detection bottle body of the existing detection device is fixedly installed, resulting in the size specifications of the bottle caps 107 that can be adapted on the detection bottle body being limited, thereby reducing the application scope of the detection device.
