[0027] When performing airtightness detection on a hose joint, the joint of the hose will be stuck in the connecting card slot 41 on the connecting seat 4. By pushing the rotating handle 23, the rotating bracket 22 can be rotated, so that the pushing plate 24 can push the sliding push rod 26 to slide along the guide sleeve 25, and the sliding push rod 26 can be positioned through the positioning mechanism 28 to prevent the sliding push rod 26 from retracting, so that the sealing cap 27 can be tightly fixed to the right end of the hose joint. Then, the hose and the tooling are placed in water, and air is inflated from the other end of the hose. By observing whether there are bubbles, it can be known whether the joint is leaking air, making the airtightness detection of the hose joint more convenient.

[0028] As shown Figure 3 in the figure, the utility model provides an airtightness detection tooling. The positioning mechanism 28 includes a sliding pull plate 281.

The right end of the plugging column 33 penetrates to the right end of the fixing slot 42 and is fixedly connected with a rotating baffle 35. The rotating baffle 35 is slidably clamped on the right side of the connecting seat 4. A fixing mechanism 36 is arranged on the outer surface of the plugging column 33. The fixing mechanism 36 includes two sliding pressing blocks 361. The two sliding pressing blocks 361 are respectively slidably connected to the upper two sides of the right side of the rotating baffle 35. An L-shaped clamping plate 362 is fixedly connected to the left end of the sliding pressing block 361. A sliding groove three is opened in the middle of the rotating baffle 35. The left end of the sliding groove three penetrates into the inside of the plugging column 33. The two L-shaped clamping plates 362 are respectively slidably connected to the upper and lower sides of the inner wall of the sliding groove three. Fixing grooves are opened on the upper and lower sides of the inner surface of the fixing slot 42. The end of the L-shaped clamping plate 362 away from the sliding pressing block 361 penetrates into the inside of the fixing groove. A guiding column 363 penetrating up and down is slidably connected in the middle of the two L-shaped clamping plates 362. The upper and lower ends of the guiding column 363 are respectively fixedly connected to the upper and lower sides of the inner wall of the sliding groove two.

The upper and lower ends of the third spring 364 are respectively fixedly connected to the opposite surfaces of the two L-shaped clamping plates 362;

[0031] When installing the connecting seat 4, by passing the rotating baffle 35 and the plugging column 33 through the fixing slot 42 and rotating the rotating baffle 35, the rotating baffle 35 can be blocked on the right side of the connecting seat 4. Under the pushing of the second spring 34, the sliding pressing plate 32 can tighten the connecting seat 4 through the rotating baffle 35 and the plugging column 33. At the same time, under the pushing of the third spring 364, the L-shaped clamping plate 362 can be clamped into the fixing groove, and the position of the plugging column 33 can be fixed, which facilitates the fixing of the connecting seat 4. At the same time, by only pressing the sliding pressing block 361, the L-shaped clamping plate 362 can be retracted from the inside of the fixing groove along the guiding column 363 and the rotating baffle 35 can be rotated back, and then the connecting seat 4 can be disassembled, making the disassembly and assembly of the connecting seat 4 more convenient and facilitating the airtightness detection of different models of hose joints by the airtightness detection tooling.

[0032] Next, the working principle of the airtightness detection tooling will be specifically described.

[0033] As Figure 1-5As shown in the figure, when performing airtightness detection on the hose joint, by passing the rotating baffle 35 and the insertion column 33 through the fixed slot 42 and rotating the rotating baffle 35, the rotating baffle 35 can be blocked on the right side of the connecting seat 4. Under the pushing of the third spring 364, the L-shaped clamping plate 362 can be clamped into the fixed clamping groove, so as to fix the position of the insertion column 33, which facilitates the fixation of the connecting seat 4. Then, the joint of the hose is clamped in the connecting clamping groove 41 on the connecting seat 4. By pushing the rotating handle 23, the pushing plate 24 can be made to push the sliding push rod 26 to slide, so that the sealing cap 27 can be tightly fixed at the right end of the hose joint. Then, the hose and the tooling are placed in water, and air is inflated from the other end of the hose. By observing whether there are bubbles, it can be known whether the joint leaks air, making the airtightness detection of the hose joint more convenient.

However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
