[0025] The T-tube 5 is quickly fixed and positioned by the fixing mechanism 3 and the positioning mechanism 4, so as to facilitate the subsequent detection of the T-tube 5. After the T-tube 5 is fixed, the T-tube 5 is detected by the auxiliary mechanism 2.

[0026] like Figure 2 , Figure 3 As shown, the left end of the threaded rod 21 is rotatably connected to a connecting plate 22, the front and rear parts of the right end of the connecting plate 22 are fixedly connected to a guide rod 23, the outer wall of the guide rod 23 is slidably connected to the top of the mounting plate 11, the left end of the connecting plate 22 is overlapped with a sealing plug 24, and the inner wall of the sealing plug 24 and the inner wall of the connecting plate 22 are threadedly connected with bolts 25.

[0027] By rotating the threaded rod 21, the threaded rod 21 moves on the inner wall of the mounting plate 11, driving the connecting plate 22 to move synchronously, and the connecting plate 22 drives the guide rod 23 to slide synchronously on the inner wall of the mounting plate 11, and the guide rod 23 limits and guides the connecting plate 22, so that the connecting plate 22 can only move horizontally when moving. At the same time, the connecting plate 22 drives the sealing plug 24 to move synchronously, so that the outer wall of the sealing plug 24 is plugged with the inner wall of the side tube of the T-tube 5, thereby blocking the inner wall of the side tube of the T-tube 5. Subsequently, the through holes at both ends of the T-tube 5 are ventilated and then put into water to detect whether there is leakage at the opening position, which has the effect of detecting air tightness.

[0028] like Figure 2 , Figure 4As shown, the bottom of the support plate 31 is fixedly connected to the fixed plate 32, the inner wall of the fixed plate 32 is rotatably connected to the rotating rod 33, the outer wall of the rotating rod 33 is fixedly connected to the worm 34, the outer wall of the worm 34 is meshed with a worm wheel 35, the axis of the worm wheel 35 is fixedly connected to the sleeve 36, the bottom end of the sleeve 36 is rotatably connected to the inner cavity of the support plate 31, the inner wall of the sleeve 36 is threadedly connected to a threaded rod 37, the top of the threaded rod 37 is rotatably connected to a clamping plate 371, and the outer wall of the clamping plate 371 is overlapped with a T-tube 5.

[0029] By rotating the rotating rod 33, the rotating rod 33 drives the worm 34 to rotate, and the worm 34 meshes with the worm wheel 35, driving the sleeve 36 to rotate synchronously. When the sleeve 36 rotates, the threaded rod 2 37 moves downward on the inner wall of the sleeve 36, and the threaded rod 2 37 drives the clamping plate 1 371 to move upward synchronously. The clamping plate 1 371 drives the T-tube 5 to move synchronously. When moving, under the action of the gravity of the T-tube 5, the clamping plate 1 371 is restricted to prevent the clamping plate 1 371 from rotating. When the height of the T-tube 5 is appropriate, the rotating rod 33 can be stopped.

[0030] like Figure 2 , Figure 4 As shown, the left and right positions on the top of the support plate 31 are both threadedly connected with threaded rods 38, one end of the threaded rods 38 is rotatably connected with a clamping plate 2 381, and the outer wall of the clamping plate 2 381 overlaps the outer wall of the T-tube 5.

[0031] By rotating the threaded rod three 38, the threaded rod three 38 moves on the inner wall of the support plate 31, driving the clamping plate two 381 to move synchronously, so that the outer wall of the clamping plate two 381 overlaps the outer wall of the T-tube 5. When the outer wall of the clamping plate two 381 is in tight contact with the outer wall of the T-tube 5, the rotation of the threaded rod three 38 can be stopped.

[0032] like Figure 2 , Figure 5 As shown, the front and rear parts of the outer wall of the threaded rod 41 are threadedly connected with a slider 42, the outer wall of the slider 42 is slidably connected to the inner cavity of the bottom plate 1, the top of the slider 42 is rotatably connected to a movable rod 43, the top of the movable rod 43 is rotatably connected to a support seat 44, the inner wall of the support seat 44 overlaps the outer wall of the T-tube 5, the top of the support seat 44 is fixedly connected to a spring 45, one end of the spring 45 is fixedly connected to an auxiliary plate 46, and the outer wall of the auxiliary plate 46 overlaps the outer wall of the T-tube 5.

[0033] The outer wall of the side tube of the T-tube 5 is overlapped with the inner wall of the support seat 44, so that the outer wall of the side tube of the T-tube 5 is overlapped with the outer wall of the auxiliary plate 46. Under the action of the elastic force of the spring 45, the side tube of the auxiliary T-tube 5 is quickly positioned. Then, according to the size of the T-tube 5, the device is adjusted, and the threaded rod four 41 is rotated to make the slider 42 slide on the outer wall of the threaded rod four 41. The slider 42 drives the movable rod 43 to move synchronously, so that the movable rod 43 rotates, driving the support seat 44 to move upward synchronously, and the support seat 44 drives the side tube of the T-tube 5 to move synchronously. When the height of the T-tube 5 is appropriate, the threaded rod four 41 can be stopped from rotating, thereby quickly positioning the T-tube 5, achieving a positioning effect.

[0034] The working principle of the utility model is as follows: when in use, the T-tube 5 is placed on the support plate 31, so that the outer wall of the T-tube 5 overlaps with the outer wall of the tight plate 371, and then the outer wall of the side tube of the T-tube 5 overlaps with the inner wall of the support seat 44, so that the outer wall of the side tube of the T-tube 5 overlaps with the outer wall of the auxiliary plate 46, and under the action of the elastic force of the spring 45, the side tube of the auxiliary T-tube 5 is quickly positioned, and then the device is adjusted according to the size of the T-tube 5. First, the center position of the T-tube 5 is determined so that it is on the same horizontal line with the center point of the sealing plug 24, and the rotating rod 33 is rotated to make the rotating rod 33 drive the worm 34 to rotate, and the worm 34 The threaded rod 37 is meshed with the worm gear 35 to drive the sleeve 36 to rotate synchronously. When the sleeve 36 rotates, the threaded rod 37 moves downward on the inner wall of the sleeve 36, and the threaded rod 37 drives the clamping plate 371 to move upward synchronously. The clamping plate 371 drives the T-tube 5 to move synchronously. When moving, under the action of the gravity of the T-tube 5, the clamping plate 371 is restricted to prevent the clamping plate 371 from rotating. At the same time, the threaded rod 41 is rotated to make the slider 42 slide on the outer wall of the threaded rod 41. The slider 42 drives the movable rod 43 to move synchronously, so that the movable rod 43 rotates, driving the support seat 44 to move upward synchronously, and the support seat 44 drives the T-tube 5 The side tubes move synchronously. When the height of the T-tube 5 is appropriate, the rotation of the rotating rod 33 and the threaded rod four 41 can be stopped, thereby quickly positioning the T-tube 5 and achieving a positioning effect. Subsequently, the threaded rod three 38 is rotated to make the threaded rod three 38 move on the inner wall of the support plate 31, driving the clamping plate two 381 to move synchronously, so that the outer wall of the clamping plate two 381 overlaps the outer wall of the T-tube 5. When the outer wall of the clamping plate two 381 is tightly against the outer wall of the T-tube 5, the rotation of the threaded rod three 38 can be stopped, thereby fixing the T-tube 5 and achieving a fixing effect. Subsequently, the airtightness test can be started, and the threaded rod one 21 is rotated to make the threaded rod three 38 move on the inner wall of the support plate 31, driving the clamping plate two 381 to move synchronously, so that the outer wall of the clamping plate two 381 overlaps the outer wall of the T-tube 5. The rod 21 moves on the inner wall of the mounting plate 11, driving the connecting plate 22 to move synchronously, and the connecting plate 22 drives the guide rod 23 to slide synchronously on the inner wall of the mounting plate 11, and the guide rod 23 limits and guides the connecting plate 22, so that the connecting plate 22 can only move horizontally when moving. At the same time, the connecting plate 22 drives the sealing plug 24 to move synchronously, so that the outer wall of the sealing plug 24 is plugged into the inner wall of the side tube of the T-tube 5, thereby sealing the inner wall of the side tube of the T-tube 5. Subsequently, the through holes at both ends of the T-tube 5 are ventilated and then put into water to detect whether there is any leakage at the opening position, which has the effect of detecting air tightness, thereby greatly improving the user experience.
