At this time, due to the relatively low center of gravity of the transparent water container 5 and the water inside, the rotation of the transparent water container 5 can be restricted by the rotation restraint shaft one 7, and the rotation of the outer frame 8 can be restricted by the rotation restraint shaft two 9, so that the transparent water container 5 can always be in a vertically hanging state. When in use, the exhaust mechanism is opened, and the bottom end of the sealed contact cover 1 can be attached to the detection position of the rubber boat. If there is an air leakage phenomenon, the exhausted gas will pass through the adjustment card 12 and act on the water in the rigid tube 3 to generate bubbles.

[0025] The strap mechanism includes a long connecting frame 10, straps 11, and adjustment cards 12. The front end of the rotation restraint shaft two 9 is connected to the middle of the rear end of the long connecting frame 10.

[0030] In summary, when a rubber boat airtightness detection device is in use, first, half of the water is filled in the transparent water container 5, and then the handle piece 19 is screwed to screw the inner-threaded cover 4 onto the outside of the external thread port 6. Then, the two sets of straps 11 are respectively wound around both sides of the forearm and tightened by adjusting the clamp 12, and the device can be connected through the long connecting frame 10. At this time, since the center of gravity of the transparent water container 5 and the water inside is relatively low, the rotation of the transparent water container 5 can be restricted by the rotation restraint shaft one 7, and the rotation of the outer frame 8 can be restricted by the rotation restraint shaft two 9, so that the transparent water container 5 can always be in a vertically hanging state. When in use, by turning the wrench 15, the valve plate 16 can be connected and moved to open and close through the rotating shaft 14. When the valve plate 16 is opened, the inside and outside of the transparent water container 5 can communicate with each other. By holding the rigid handle sleeve 20, the bottom end of the sealing contact cover 1 is attached to the detection position of the rubber boat. If there is an air leakage phenomenon, the discharged gas will pass through the adjusting clamp 12 and act on the water through the rigid pipe 3 to generate bubbles. In addition, under the connection of the connecting frame 17, the sealing contact cover 1 can be clamped by the clamping frame 18, which is convenient for storage when not in use.
