[0020] In this embodiment, flanges 2 are respectively provided at the left and right ends of the connecting pipe 1 , and a plurality of through holes 3 are provided on the two flanges 2 for fixing bolts to pass through.

[0021] In this embodiment, the lifting assembly includes a limit assembly, a rack 10, a rotating column 11, a gear 12 and a fixed assembly. The limit assembly is arranged on the rear side of the inner cavity of the fixed box 7, and the rack 10 is arranged at the front end of the limit assembly. One end of the rotating column 11 is rotatably connected to the left side of the inner cavity of the fixed box 7 through a bearing, and the other end of the rotating column 11 extends to the right side of the fixed box 7 and is connected to the fixed assembly. The gear 12 is fixedly sleeved on the outer wall of the rotating column 11 and meshes with the rack 10. The top end of the rack 10 extends to the top end of the fixed box 7 and is fixedly connected to the flow meter 6. By rotating the rotating column 11, it drives the gear 12 rotates, and since the rack 10 is meshed with the gear 12, when the gear 12 rotates, the rack 10 can slide up and down along a straight line under the limiting action of the slide groove 8 and the slide bar 9, so that the height of the flow meter 6 can be adjusted, and the height of the flow meter 6 can be conveniently adjusted according to actual usage conditions, thereby improving the practicability and flexibility of the device when in use, and solving the problem that the height of the flow meter 6 in the prior art is fixed during actual use, and the distance between the flow meter 6 and the pipeline cannot be adjusted, and when the pipeline is at a higher position, it is inconvenient for the user to check the count on the flow meter 6.

[0022] In this embodiment, the limit assembly includes a slide groove 8 and a slide bar 9. The slide groove 8 is opened on the rear side of the inner cavity of the fixed box 7. The slide bar 9 can be slidably inserted in the inner cavity of the slide groove 8 and fixedly connected to the rack 10. Under the joint action of the slide groove 8 and the slide bar 9, the flow meter 6 can always slide up and down along a straight line, and the rack 10 and the gear 12 can always remain in meshing. The inner cavity of the slide groove 8 and the outer wall of the slide bar 9 are adapted to each other and are both in a "T" shape, so that the slide bar 9 can always remain inserted in the inner cavity of the slide groove 8 to prevent the slide bar 9 from escaping from the inner cavity of the slide groove 8.

[0023] In this embodiment, the fixing assembly includes a fixing hole 13, a fixing rod 14, a rotating cylinder, a limiting plate 15, a spring 16 and a connecting assembly. Several fixing holes 13 are opened in an arc shape on the right side of the fixing box 7. Two fixing rods 14 are respectively detachably inserted into the inner cavities of two of the fixing holes 13. The rotating cylinder can be slidably sleeved on the right end of the rotating column 11 and fixedly connected to the two fixing rods 14. The limiting plate 15 can be slidably embedded in the inner cavity of the fixing cylinder 19 and fixedly connected to the right end of the rotating column 11. The spring 16 is sleeved on the right end of the rotating column 11. One end of the spring 16 is fixedly connected to the left side of the inner cavity of the fixing cylinder 19, and the other end of the spring 16 is fixedly connected to the limiting plate 15. The two connecting assemblies are respectively arranged on the upper and lower sides of the inner cavity of the fixing cylinder 19 and are both fixed to the limiting plate 15. The plate 15 is fixedly connected, and the fixing cylinder 19 is pulled to make the fixing rod 14 disengage from the inner cavity of the fixing hole 13, and the limiting plate 15 squeezes the spring 16, so that the spring 16 produces corresponding elastic deformation, and then generates corresponding elastic force. At this time, the fixing cylinder 19 is rotated to make the fixing cylinder 19 drive the limiting plate 15 and the rotating column 11 to rotate through the connecting block 18 and the connecting groove 17. After the flow meter 6 is adjusted to a suitable height, the fixing cylinder 19 is released. Under the elastic force of the spring 16, the fixing cylinder 19 can be reset, and then the fixing rod 14 can be inserted into the corresponding inner cavity of the fixing hole 13. Under the joint action of the fixing rod 14 and the fixing hole 13, the angle of the fixing cylinder 19 can be fixed, and then the angle of the rotating column 11 can be fixed, so that the height of the rack 10 and the flow meter 6 is fixed.

[0024] In this embodiment, the connecting component includes a connecting groove 17 and a connecting block 18. The connecting groove 17 is opened on one side of the inner wall of the fixed cylinder 19. The connecting block 18 can be slidably embedded in the inner cavity of the connecting groove 17 and fixedly connected to one side of the outer wall of the limiting plate 15. Under the interaction between the connecting groove 17 and the connecting block 18, the limiting plate 15 and the rotating column 11 can be driven to rotate when the fixed cylinder 19 rotates. The inner cavity of the connecting groove 17 and the outer wall of the connecting block 18 are adapted to each other and are both dovetail-shaped.

[0025] In this embodiment, a plurality of anti-slip grooves 8 are provided on the outer circumference of the fixing cylinder 19, which can increase the roughness of the outer circumference of the fixing cylinder 19, thereby preventing the fixing cylinder 19 from slipping out of the hand when rotating, thereby improving the stability of the device when in use.

[0026] The use method and advantages of the utility model: When in use, the working process is as follows:

[0027] By setting the flange 2 and the through hole 3 opened on the flange 2, it is convenient to use fasteners such as bolts to connect the connecting pipe 1 to the pipeline for flow monitoring, detect the flow in the connecting pipe 1 through the probe 4, and transmit the flow information to the flow meter 6 for display through the wiring harness 5. When adjusting the height of the flow meter 6, pull the fixing cylinder 19 to make the fixing rod 14 disengage from the inner cavity of the fixing hole 13, and make the limiting plate 15 squeeze the spring 16, so that the spring 16 produces corresponding elastic deformation and then generates corresponding elastic force. At this time, rotate the fixing cylinder 19 so that the fixing cylinder 19 drives the limiting plate 15 and the rotating column 11 to rotate through the connecting block 18 and the connecting groove 17, thereby making the gear 12 rotate synchronously. Since the rack 10 is meshed with the gear 12, when the gear 12 rotates, the rack 10 can be limited by the slide groove 8 and the slide bar 9. The height of the flow meter 6 can be adjusted by sliding up and down along a straight line. The height of the flow meter 6 can be conveniently adjusted according to actual usage conditions, which improves the practicability and flexibility of the device when in use. It solves the problem that the height of the flow meter 6 in the prior art is fixed during actual use, and the distance between the flow meter 6 and the pipeline cannot be adjusted. When the pipeline is at a higher position, it is inconvenient for the user to check the count on the flow meter 6. After the flow meter 6 is adjusted to a suitable height, the fixing cylinder 19 is loosened. Under the elastic force of the spring 16, the fixing cylinder 19 can be reset, and then the fixing rod 14 can be inserted into the corresponding inner cavity of the fixing hole 13. Under the joint action of the fixing rod 14 and the fixing hole 13, the angle of the fixing cylinder 19 can be fixed, and then the angle of the rotating column 11 can be fixed, and the height of the rack 10 and the flow meter 6 can be fixed.
