[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 - Figure 4 As shown, this embodiment provides a vacuum pipe measuring device, including a vacuum pipe body 1 and a threaded groove 15, a pair of first arc-shaped movable plates 10 are sleeved on the outer wall of the vacuum pipe body 1, a second arc-shaped movable plate 11 is hinged on the rear side of the first arc-shaped movable plate 10, a first sealing gasket 12 is fixedly connected to the inner wall of the second arc-shaped movable plate 11, a second sealing gasket 13 is provided on the inner wall of the first arc-shaped movable plate 10, a bellows 14 is fixedly connected between the two first arc-shaped movable plates 10, the inner wall of the threaded groove 15 is fitted with the vacuum pipe body 1, a threaded ring 16 is connected to the inner thread of the threaded groove 15, a gas leakage measuring instrument body 17 is installed on the upper end of the threaded ring 16, and the vacuum pipe body 1 is respectively fitted with the inner walls of the first sealing gasket 12 and the second sealing gasket 13.

[0021] The above working principle: when it is necessary to perform an airtightness test on the vacuum pipe body 1, firstly, the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11 are respectively mounted on the vacuum pipe body 1, and then the distance between the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11 is adjusted, and at the same time, the bellows 14 between the two first arc-shaped movable plates 10 can seal the vacuum pipe body 1, and the first sealing gasket 12 on the first arc-shaped movable plate 10 and the second sealing gasket 13 on the second arc-shaped movable plate 11 can seal both sides of the vacuum pipe body 1, and finally, the gas leaked in the vacuum pipe body 1 can enter the threaded ring 16 through the thread groove 15 and then pass through the gas leakage measuring instrument body 17 to perform an airtightness test on the vacuum pipe body 1, thereby reducing the situation where it is impossible to determine whether there is a gas leak in the vacuum pipe during use, and the staff needs to slowly check the pipe.

[0022] In order to enable the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11 to be fixed after being moved during use, a hole groove for the rotation of the limiting threaded rod 18 is opened in the first arc-shaped movable plate 10, and a limiting hole threadedly connected to the limiting threaded rod 18 is opened in the second arc-shaped movable plate 11. By rotating the limiting threaded rod 18, the limiting threaded rod 18 is threadedly connected to the limiting hole on the second arc-shaped movable plate 11, so as to fix the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11.

[0023] Taking into account that the second sealing gasket 13 needs to fit tightly against the vacuum pipe body 1 during use, a pushing threaded column 19 is fixedly connected to the outer wall of the second sealing gasket 13, and a through hole threadedly connected to the pushing threaded column 19 is opened inside the first arc-shaped movable plate 10. The second sealing gasket 13 is driven to fit tightly against the vacuum pipe body 1 by rotating the pushing threaded column 19.

[0024] The device will need to be supported and kept stable during use, so the outer wall of the second curved movable plate 11 on the right is fixedly connected to the first supporting rod 2, and the outer wall of the second curved movable plate 11 on the left is fixedly connected to the second supporting rod 20. A reserved groove for the sliding of the second supporting rod 20 is provided inside the first supporting rod 2. The device is supported by the first supporting rod 2 and the second supporting rod 20, so that the device can remain stable during use.

[0025] In the process of adjusting the first supporting rod 2 and the second supporting rod 20 during operation, it is necessary to limit them, so a plurality of L-shaped limit rods 21 are provided on the upper side of the first supporting rod 2, and a plug-in groove slidably connected to the L-shaped limit rod 21 is provided on the outer wall of the first supporting rod 2, and the plug-in groove is connected to the reserved groove; a plug-in hole slidably connected to the L-shaped limit rod 21 is provided on the outer wall of the second supporting rod 20, and the plug-in groove is connected to the plug-in hole, and the adjusted first supporting rod 2 and the second supporting rod 20 are limited by the L-shaped limit rod 21.

[0026] In addition, during the use of the first sealing gasket 12 and the second sealing gasket 13, the gas in the pipeline may corrode them, so the surfaces of the second sealing gasket 13 and the first sealing gasket 12 are coated with a corrosion-resistant coating. The corrosion-resistant coating coated on the surfaces of the first sealing gasket 12 and the second sealing gasket 13 protects them and extends the service life of the device.

[0027] When the vacuum pipe measuring device in this embodiment is used specifically, when it is necessary to perform an airtightness test on the vacuum pipe body 1, the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11 are respectively mounted on the vacuum pipe body 1, and then the distance between the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11 is adjusted. At the same time, the bellows 14 between the two first arc-shaped movable plates 10 can seal the vacuum pipe body 1, and the first sealing gasket 12 on the first arc-shaped movable plate 10 and the second sealing gasket 13 on the second arc-shaped movable plate 11 can seal both sides of the vacuum pipe body 1. Finally, the gas leaked in the vacuum pipe body 1 can enter the threaded ring 16 through the threaded groove 15 and then pass through the gas leakage measuring instrument body 17 to perform an airtightness test on the vacuum pipe body 1. When it is necessary to adjust the first sealing gasket 12, rotate and push the threaded column 19 to make the first sealing gasket 12 cooperate with the second sealing gasket 13 to seal both sides of the vacuum pipe body 1; when the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11 are moved to appropriate positions, the limiting threaded rod 18 can be rotated to fix the first arc-shaped movable plate 10 and the second arc-shaped movable plate 11; when it is necessary to transport the device, the first supporting rod 2 and the second supporting rod 20 can be used to support the device, so that the device is more stable during use; at the same time, the L-shaped limiting rod 21 can limit and fix the first supporting rod 2 and the second supporting rod 20, thereby solving the problem that during the use of the vacuum pipe, it is impossible to determine whether there is a gas leak in the pipe, and the staff needs to slowly check the pipe.
