[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] The preferred embodiment of the airtightness detection device provided by the present utility model is as follows: Figures 1 to 6As shown: the air tightness detection equipment includes a water tank 1, the top of the water tank 1 is fixedly connected to a side plate 5, the surface of the side plate 5 is fixedly connected to a servo motor 2, the output end of the servo motor 2 is fixedly connected to a screw 3 rotatably connected to the side plate 5, the surface of the screw 3 is threadedly connected to a lifting plate 4 slidably connected to the side plate 5, the top of the lifting plate 4 is fixedly connected to a blowing device 6, the bottom air outlet of the blowing device 6 is fixedly connected to a conduit 7, the bottom of the conduit 7 is fixedly connected to a connecting pipe 8 fixedly connected to the lifting plate 4, the bottom of the connecting pipe 8 is fixedly connected to an insertion pipe 9, the surface of the insertion pipe 9 is fixedly connected to a first connecting plate 10, a bolt 11 is inserted into the inside of the first connecting plate 10, a nut 12 is threadedly connected to the surface of the bolt 11, the bottom of the first connecting plate 10 is fitted with a second connecting plate 13 slidably connected to the bolt 11, the bottom of the second connecting plate 13 is fixedly connected to a connecting pipe 14, the bottom of the connecting pipe 14 is fixedly connected to a sealing head 15, and the surface of the sealing head 15 is sleeved with a pipe fitting 16.

[0030] In this embodiment, the screw 3 is arranged at the center line of the lifting plate 4, and the lifting plate 4 is lifted and lowered horizontally along the side plate 5 through the screw 3. The movement of the lifting plate 4 can drive the pipe fitting 16 to move to a position in contact with the rubber pad 18.

[0031] In this embodiment, the conduit 7, the connecting tube 8, the insertion tube 9, the connecting tube 14 and the sealing head 15 are interconnected. The blowing device 6 is turned on so that the gas it blows out passes through the connecting tube 8, the connecting tube 14 and the sealing head 15 and enters the interior of the pipe fitting 16.

[0032] In this embodiment, the catheter 7 and the insertion tube 9 are steel tubes. The bottom of the insertion tube 9 is embedded in the interior of the connecting tube 14. Under the transmission of the lifting plate 4, the pipe fitting 16 will be controlled to fit tightly with the bottom of the rubber pad 18, thereby sealing the top of the pipe fitting 16.

[0033] In this embodiment, the first connecting plate 10 and the second connecting plate 13 are parallel to each other. When the insertion tube 9 is embedded in the connecting tube 14, the first connecting plate 10 and the second connecting plate 13 are tightly fitted. Since the pipe fittings 16 to be inspected are of different sizes, the sealing head 15 cannot fit tightly with different pipe fittings 16. At this time, the nut 12 on the surface of the bolt 11 can be unscrewed, and the second connecting plate 13 can be removed from the bottom of the first connecting plate 10 to achieve the purpose of replacing the sealing head 15.

[0034] Example 2

[0035] On the basis of Example 1, a preferred embodiment of the airtightness detection device provided by the present invention is as follows: Figures 1 to 6As shown: a water filling port 17 is provided on the right side of the water tank 1, a rubber pad 18 is fixedly connected to the inside of the water tank 1, an electric push rod 19 is fixedly connected to the top of the water tank 1, the output end of the electric push rod 19 is fixedly connected to a transmission plate 20, two groups of transmission rods 21 are fixedly connected to the side of the transmission plate 20, a socket 25 located at the top of the water tank 1 is provided below the transmission plate 20, and slides 22 that are slidably connected to the water tank 1 are provided on both sides of the socket 25, and one end of the two groups of slides 22 close to the socket 25 is fixedly connected to a fixed head 23, and the top of the two groups of slides 22 is fixedly connected to a control plate 24 that is slidably connected to the transmission rod 21.

[0036] In this embodiment, the centers of the jack 25 and the sealing head 15 are located at the same point, and the jack 25 is larger than the pipe 16 . The slightly larger size of the jack 25 facilitates the insertion of pipes 16 of different sizes into the water tank 1 .

[0037] In this embodiment, the transmission rod 21 and the transmission plate 20 are perpendicular to each other, and the transmission rod 21 fits tightly with the internal inclined groove of the control plate 24. When the electric push rod 19 is turned on, it pushes the transmission plate 20 to descend, and the transmission rod 21 also descends. Since the transmission rod 21 is embedded in the internal inclined groove of the slide plate 22, when the transmission rod 21 descends, it will drive the two sets of fixed heads 23 closer to each other through the inclined surface.

[0038] In this embodiment, the two sets of fixing heads 23 are both arranged on the central axis of the jack 25. The two sets of fixing heads 23 slide in opposite directions through the transmission rod 21. By setting the fixing heads 23, the undetected parts of the pipe 16 can be tightened.

[0039] In this embodiment, the rubber pad 18 completely covers the bottom of the water tank 1. Under the transmission of the lifting plate 4, the pipe fitting 16 will be controlled to fit tightly with the bottom of the rubber pad 18. At this time, the top and bottom of the pipe fitting 16 are sealed by the sealing head 15 and the rubber pad 18 respectively.

[0040] The working principle and use process of the utility model are as follows: First, the pipe fitting 16 to be tested is engaged with the sealing head 15, so that the sealing head 15 is tightly fitted with the inside of the pipe fitting 16, and then the servo motor 2 is turned on to control the rotation of the screw 3. When the screw 3 rotates, the lifting plate 4 is driven to descend, thereby driving the pipe fitting 16 to descend and pass through the jack 25 into the water tank 1. Under the drive of the lifting plate 4, the pipe fitting 16 is controlled to fit tightly with the bottom of the rubber pad 18. At this time, the top and bottom of the pipe fitting 16 are respectively blocked by the sealing head 15 and the rubber pad 18, and the blowing device 6 is turned on. , so that the blown gas passes through the connecting pipe 8, the connecting pipe 14 and the sealing head 15 into the interior of the pipe fitting 16. At this time, observe the surface of the pipe fitting 16 through the water tank 1. If bubbles appear on the surface of the pipe fitting 16, it means that there are cracks on the surface of the pipe fitting 16 and the air tightness is poor. Since the pipe fittings 16 to be tested are of different sizes, the sealing head 15 cannot fit tightly with different pipe fittings 16. At this time, the nut 12 on the surface of the bolt 11 can be unscrewed, and the second connecting plate 13 can be removed from the bottom of the first connecting plate 10 to achieve the purpose of replacing the sealing head 15.

[0041] When the pipe fitting 16 is being inspected, the electric push rod 19 can be turned on to push the transmission plate 20 downward, and the transmission rod 21 will then descend. Since the transmission rod 21 is embedded in the internal inclined groove of the slide plate 22, when the transmission rod 21 descends, it will drive the two sets of fixing heads 23 closer to each other through the inclined surface, thereby tightening the uninspected parts of the pipe fitting 16.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
