Description

Technical Field

[0001] This utility model relates to the field of gas ultrasonic flow meter transducers, and in particular to a fixing structure for a gas ultrasonic flow meter transducer. Background Technology

[0002] The transducer of a gas ultrasonic flow meter is a key component of the ultrasonic flow meter, used to measure gas flow. Thanks to its structural design and technological advantages, the gas ultrasonic flow meter transducer plays a vital role in gas flow measurement and is widely used in flow measurement and control of various gas equipment. The ingeniously designed mounting structure of the gas ultrasonic flow meter transducer ensures its stability and accuracy within the gas ultrasonic flow meter, while simultaneously reducing costs and extending its service life.

[0003] In the existing technology, the gas ultrasonic flow meter transducer needs to be disassembled when it needs to be replaced or repaired. However, disassembling the transducer by removing the nut requires tools, which is troublesome and inconvenient to use. Therefore, it is necessary to improve the fixing structure of the gas ultrasonic flow meter transducer to solve the above problems. Utility Model Content

[0004] To overcome the problem that gas ultrasonic flow meter transducers need to be disassembled when they need to be replaced or repaired, but disassembling the transducer by removing the nut requires tools and is troublesome to install and disassemble.

[0005] The technical solution of this utility model is as follows: a fixed structure for a gas ultrasonic flow meter transducer, including a frame, a fixed semicircular block, a first sliding shaft, a sliding semicircular block, and an adjustment component. The adjustment component is provided on the outside of the frame, the fixed semicircular block is fixedly connected to the top of the frame, the first sliding shaft is slidably connected inside the fixed semicircular block, the sliding semicircular block is fixedly connected to the outside of the first sliding shaft, and the sliding semicircular block is slidably connected inside the frame, so that the sliding semicircular block slides inside the frame through the first sliding shaft.

[0006] Preferably, by rotating the limiting block 90 degrees, it can pass through the corresponding side groove of the base, allowing the sliding semicircular block and the first sliding shaft to slide inside the frame. Then, by placing the gas ultrasonic flow meter transducer body at the fixed semicircular block, its convex strip contacts the corresponding convex strip of the fixed semicircular block. The limiting block is then slid through the sliding semicircular block, allowing it to pass through the groove into the base. Rotating the limiting block 90 degrees prevents the sliding semicircular block from moving. Thus, by rotating the limiting block, the gas ultrasonic flow meter transducer body can be replaced, improving the efficiency of replacing the transducer body and saving time. Through the extension frames fixed on both sides of the frame, the second sliding shaft is driven by pushing the dial outwards, and then extended through the extension tubes on both sides. A spring returns the second sliding shaft to the corresponding groove of the extension tube, preventing movement of the extension tube and fixing it. This allows the two flanges on the outside of the extension tube to adjust the extension length of the gas ultrasonic flow meter transducer according to the distance between the pipes, improving the practicality and working efficiency of the gas ultrasonic flow meter transducer.

[0007] Preferably, the frame has a groove at the corresponding position of the sliding semicircular block, and the sliding semicircular block slides in the groove. The groove limits the sliding semicircular block and prevents it from falling off.

[0008] Preferably, a base is fixedly connected to the top of the frame, a rotating shaft is rotatably connected inside the first sliding shaft, a limit block is fixedly connected to the end of the rotating shaft away from the sliding semicircular block, a first sealing strip is fixedly connected inside the frame, and a gas ultrasonic flow meter transducer body is movably connected inside the frame. The gas ultrasonic flow meter transducer body is movably connected inside the fixed semicircular block and the sliding semicircular block, and a protruding strip is fixedly connected to the outside of the gas ultrasonic flow meter transducer body. By rotating the limit block 90 degrees, it can pass through the corresponding side groove of the base, allowing the sliding semicircular block and the first sliding shaft to slide inside the frame. Then, by placing the gas ultrasonic flow meter transducer body at the fixed semicircular block, its protruding strip contacts the corresponding convex strip of the fixed semicircular block. By sliding the sliding semicircular block, the limit block passes through the groove of the base. Then, by rotating the limit block 90 degrees, it prevents the sliding semicircular block from moving. Thus, by rotating the limit block, the gas ultrasonic flow meter transducer body can be replaced, improving the efficiency of replacing the gas ultrasonic flow meter transducer body and saving time.

[0009] Preferably, the fixed semicircular block and the sliding semicircular block are provided with convex strips at corresponding positions of the convex strips. The convex strips contact each other, and the contact between the convex strips fixes the transducer body of the gas ultrasonic flow meter, preventing it from moving.

[0010] Preferably, the base has a groove at the corresponding position of the limiting block, and the limiting block moves in the groove. The groove allows the limiting block to fix or slide the sliding semicircular block, improving practicality.

[0011] Preferably, the adjustment assembly includes an extension frame, which is fixedly connected to the outside of the frame. An extension tube is slidably connected inside the extension frame, and a flange is fixedly connected to the outside of the extension tube. A second sealing strip is fixedly connected inside the extension frame, and a second sliding shaft is slidably connected inside the extension frame. A dial is fixedly connected to the end of the second sliding shaft away from the extension tube. A spring is fixedly connected between the dial and the extension frame. By moving the dial outward, the second sliding shaft is driven, and then extended through the extension tubes on both sides. The spring returns the second sliding shaft to the corresponding groove of the extension tube, preventing the extension tube from moving and fixing the extension tube. Thus, the two flanges on the outside of the extension tube can adjust the extension length of the ultrasonic flow meter transducer according to the distance between the pipes, thereby improving the practicality of the gas ultrasonic flow meter transducer.

[0012] Preferably, the extension frame has a groove at the corresponding position of the extension tube, and the extension tube moves in the groove, allowing it to slide and improving stability.

[0013] Preferably, the extension tube has a groove at the corresponding position of the second sliding shaft. The second sliding shaft moves in the groove, and the spring of the groove can reset the second sliding shaft to contact the corresponding groove of the extension tube, so as to fix the extension length of the extension tube and prevent it from sliding.

[0014] The beneficial effects of this utility model are:

[0015] 1. Compared to installing and removing the transducer by removing the nut, this method involves sliding a semicircular block inside the frame, placing the transducer body of the ultrasonic gas flow meter onto the fixed semicircular block, ensuring that its convex strip contacts the corresponding convex strip of the fixed semicircular block, and then sliding the semicircular block to allow the limiting block to pass through the base from the groove. Rotating the limiting block 90 degrees prevents the sliding semicircular block from moving. This allows for easy replacement of the ultrasonic gas flow meter transducer body by rotating the limiting block, improving the efficiency of transducer replacement, saving time, and avoiding the problems of needing tools to remove the transducer when it needs replacement or maintenance.

[0016] 2. By moving the dial outward, the second sliding shaft is driven, and then extended through the extension tubes on both sides. The second sliding shaft is reset to the corresponding groove of the extension tube by the spring, so as to prevent the extension tube from moving and fix the extension tube. Thus, the two flanges on the outside of the extension tube can adjust the extension length of the ultrasonic flow meter transducer according to the distance between the pipes, thereby improving the practicality of the gas ultrasonic flow meter transducer.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of a fixing structure for a gas ultrasonic flow meter transducer, including a frame 1, a fixed semicircular block 21, a first sliding shaft 23, a sliding semicircular block 24, and an adjustment component. The adjustment component is provided on the outer side of the frame 1, and the fixed semicircular block 21 is fixedly connected to the top of the frame 1. The first sliding shaft 23 is slidably connected inside the fixed semicircular block 21, and the sliding semicircular block 24 is fixedly connected to the outside of the first sliding shaft 23. The sliding semicircular block 24 is slidably connected inside the frame 1, and slides inside the frame 1 through the first sliding shaft 23. The frame 1 has a groove at a corresponding position of the sliding semicircular block 24, and the sliding semicircular block 24 slides in the groove. The groove limits the sliding semicircular block 24 and prevents it from falling off.

[0025] Please see Figures 2-3 In this embodiment, a base 22 is fixedly connected to the top of the frame 1. A rotating shaft 25 is rotatably connected inside the first sliding shaft 23. A limiting block 26 is fixedly connected to the end of the rotating shaft 25 away from the sliding semicircular block 24. A first sealing strip 27 is fixedly connected inside the frame 1. A gas ultrasonic flow meter transducer body 29 is movably connected inside the frame 1. The gas ultrasonic flow meter transducer body 29 is movably connected inside the fixed semicircular block 21 and the sliding semicircular block 24. A protrusion 28 is fixedly connected to the outside of the gas ultrasonic flow meter transducer body 29. By rotating the limiting block 26 ninety degrees, it can pass through the corresponding side groove of the base 22, allowing the sliding semicircular block 24 and the first sliding shaft 23 to slide inside the frame 1. Then, by placing the gas ultrasonic flow meter transducer body 29 at the fixed semicircular block 21, the protrusion 28 and the fixed semicircular block 21 are aligned. Corresponding convex strips contact each other, and the sliding semicircular block 24 slides to make the limiting block 26 pass through the groove into the base 22. The limiting block 26 is rotated ninety degrees to prevent the sliding semicircular block 24 from moving. Thus, by rotating the limiting block 26, the gas ultrasonic flow meter transducer body 29 can be replaced, which improves the efficiency of replacing the gas ultrasonic flow meter transducer body 29 and saves time. The fixed semicircular block 21 and the sliding semicircular block 24 are provided with convex strips at the corresponding positions of the convex strip 28. The convex strips contact each other with the convex strip 28. The contact between the convex strips and the convex strip 28 fixes the gas ultrasonic flow meter transducer body 29 and prevents it from moving. The base 22 has a groove at the corresponding position of the limiting block 26. The limiting block 26 moves in the groove. The groove allows the limiting block 26 to fix or slide the sliding semicircular block 24, which improves practicality.

[0026] Please see Figures 4-5In this embodiment, the adjustment assembly includes an extension frame 31, which is fixedly connected to the outside of the frame 1. An extension tube 32 is slidably connected inside the extension frame 31, and a flange 33 is fixedly connected to the outside of the extension tube 32. A second sealing strip 34 is fixedly connected inside the extension frame 31, and a second sliding shaft 35 is slidably connected inside the extension frame 31. A dial 36 is fixedly connected to the end of the second sliding shaft 35 away from the extension tube 32. A spring 37 is fixedly connected between the dial 36 and the extension frame 31. By moving the dial 36 outward, the second sliding shaft 35 is driven, and then extended through the extension tubes 32 on both sides. The spring 37 returns the second sliding shaft 35 to the corresponding groove in the extension tube 32, preventing the extension tube 32 from extending. 2. The extension tube 32 is fixed, so that the two flanges 33 on the outside of the extension tube 32 can adjust the extension length of the ultrasonic flow meter transducer according to the distance between the pipes, thereby improving the practicality of the gas ultrasonic flow meter transducer. The extension frame 31 has a groove at the corresponding position of the extension tube 32, and the extension tube 32 moves in the groove. The groove allows the extension tube 32 to slide, improving stability. The extension tube 32 has a groove at the corresponding position of the second sliding shaft 35, and the second sliding shaft 35 moves in the groove. The groove allows the spring 37 to reset the second sliding shaft 35, so that the second sliding shaft 35 contacts the corresponding groove of the extension tube 32, thereby fixing the extension length of the extension tube 32 and preventing it from sliding.

[0027] During operation, by rotating the limiting block 26 ninety degrees, it can pass through the corresponding side groove of the base 22, allowing the sliding semicircular block 24 and the first sliding shaft 23 to slide inside the frame 1. Then, by placing the gas ultrasonic flowmeter transducer body 29 onto the fixed semicircular block 21, its convex strip 28 contacts the corresponding convex strip of the fixed semicircular block 21. By sliding the sliding semicircular block 24, the limiting block 26 passes through the groove into the base 22. Rotating the limiting block 26 ninety degrees prevents the sliding semicircular block 24 from moving. Thus, by rotating the limiting block 26, the gas ultrasonic flowmeter transducer body 29 can be replaced, improving the gas replacement efficiency. The efficiency of the transducer body 29 of the gas ultrasonic flow meter is improved, saving time. Through the extension frames 31 fixed on both sides of the frame 1, the second sliding shaft 35 is driven by the outward movement of the dial 36, and then extended through the extension tubes 32 on both sides. The second sliding shaft 35 is reset into the corresponding groove of the extension tube 32 by the spring 37, so as to prevent the extension tube 32 from moving and fix the extension tube 32. Thus, the two flanges 33 on the outside of the extension tube 32 can adjust the extension length of the gas ultrasonic flow meter transducer according to the distance between the pipes, thereby improving the practicality and working efficiency of the gas ultrasonic flow meter transducer.

[0028] Through the above steps, the sliding semicircular block 24 is made to slide inside the frame 1 by the first sliding shaft 23, so as to solve the problem that the gas ultrasonic flow meter transducer needs to be disassembled when it needs to be replaced or repaired, but the transducer needs to be disassembled with tools when the nut is removed, which is troublesome to install and disassemble.
