It is closely related to the national economy, national defense, and scientific research, and plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially now, with the energy crisis and the increasing automation of industrial production, the status and role of flow meters in the national economy are even more prominent. A flow meter is an instrument that indicates the measured flow rate and the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow rate of fluid in pipes or open channels.

[0003] In existing technologies, most flow meters are fixed and installed using screws. This requires installers to carry a large number of screws, which are often sharp and could cause injury. Over time, the screws are prone to rusting and are difficult to disassemble. Furthermore, the mounting plate is close to the flow meter's dial, making it inconvenient to reach the wrench to tighten the nut or rotate it 360 degrees, hindering quick and easy bolt fixation. This process is time-consuming and labor-intensive, making the flow meter installation process overly cumbersome and causing significant inconvenience for both installation and daily maintenance.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5 A flow meter device that is easy to install and maintain includes a meter body 1, an installation mechanism 2 and an access pipe 3. The installation mechanism 2 is fixedly installed at both ends of the meter body 1, and the meter body 1 is movably connected to the access pipe 3 through the installation mechanism 2.

[0028] The installation mechanism 2 includes a protective shell 4. A fixing ring 5 is fixedly installed inside the protective shell 4 by a support rod 6. Three movable rods 7 are movably inserted into the inner side of the fixing ring 5. Springs are provided on the outer side of the movable rods 7. The inner sides of the three movable rods 7 overlap with the surface of the access pipe 3. Rollers 16 are rotatably connected to the outer side of the movable rods 7.

[0029] The inner wall of the protective shell 4 is slidably connected to a movable ring 11. A pressing block 15 is fixedly installed on the inner side of the movable ring 11. The side of the pressing block 15 away from the movable ring 11 overlaps with the roller 16. A through hole 14 is opened inside the movable ring 11. The support rod 6 is fixedly connected to the inner wall of the protective shell 4 through the through hole 14.

[0030] A push rod 18 is fixedly installed on the outer side of the movable ring 11, and a slide rail 17 is provided on the inner wall of the protective shell 4. The push rod 18 extends to the front side of the protective shell 4 through the slide rail 17.

[0031] By setting up the installation mechanism 2, the rotatable movable ring 11 drives the squeezing block 15 to gradually contact the movable rod 7, causing the movable rod 7 to drive the clamping plate 8 to effectively clamp the access pipe 3 located in the fixed ring 5. This allows the meter body 1 to connect the two access pipes 3 through the installation mechanism 2. Moreover, the entire installation process does not use bolt and nut connections, thus avoiding the inconvenience of bolt and nut installation. This makes the installation of the meter more convenient and provides many benefits to the staff for installation and daily maintenance.

[0032] As a specific technical solution in this embodiment, an anti-slip pad is provided at the connection between the access pipe 3 and the inner side of the protective shell 4. The anti-slip pad is an elastic rubber pad.

[0033] In this embodiment, the use of anti-slip pads makes the connection between the access pipe 3 and the protective shell 4 more stable.

[0034] As a specific technical solution in this embodiment, clamping plates 8 are fixedly installed on the opposite ends of the three movable rods 7. A wear-resistant pad is provided on the other side of the clamping plate 8. The wear-resistant pad is a soft rubber elastic pad. The clamping plate 8 overlaps with the access tube 3 through the wear-resistant pad.

[0035] In this embodiment, the use of wear-resistant pads can make the overlap relationship between the clamping plate 8 and the access pipe 3 more stable.

[0036] As a specific technical solution of this embodiment, a guide wheel 10 is fixedly installed on the outer side of the clamping plate 8, and a guide plate 9 is fixedly installed on the inner side of the fixing ring 5. The other end of the guide wheel 10 extends into the interior of the guide plate 9 and is slidably connected to the inner wall of the guide plate 9.

[0037] In this embodiment, during the movement of the movable rod 7, the guide wheel 10 slides together with the movable rod 7, so that the guide wheel 10 slides inside the guide plate 9, thereby improving the movement stability of the movable rod 7.

[0038] As a specific technical solution of this embodiment, a pulley 13 is fixedly installed on the outer side of the movable ring 11, and a groove 12 is opened on the inner wall of the protective shell 4. The pulley 13 extends into the interior of the groove 12 and is slidably connected to the inner wall of the groove 12.

[0039] In this embodiment, the pulley 13 slides along the direction of the slide groove 12 together with the movable ring 11, thereby improving the movement stability of the movable ring 11.

[0040] As a specific technical solution in this embodiment, the protective shell 4 has a cover 19 hinged to its front and a drive mechanism 20 fixedly installed thereon. The drive mechanism 20 and the push rod 18 are both located inside the cover 19, and the drive mechanism 20 and the push rod 18 are movably installed. The drive mechanism 20 includes a drive box 21, and a brake motor 22 is fixedly installed on the inner wall of the drive box 21. The output shaft of the brake motor 22 is fixedly connected to a cam 23. A deflection rod 24 is rotatably connected to the inner wall of the drive box 21. The other end of the deflection rod 24 is fixedly connected to the push rod 18. The upper surface of the deflection rod 24 overlaps with the cam 23. The lower surface of 4 is movably connected to the bottom of the inner wall of the drive box 21. A follower wheel 25 is fixedly installed inside the deflection rod 24. A directional groove 26 is opened in the inner wall of the drive box 21. The other end of the follower wheel 25 extends into the inner wall of the directional groove 26 and slides in connection with the inner wall of the directional groove 26. An abutment wheel 27 is fixedly connected to the top of the deflection rod 24. The top of the abutment wheel 27 overlaps with the bottom of the cam 23. A telescopic sleeve rod 28 is fixedly installed at the bottom of the inner wall of the drive box 21. A spring is provided on the outer side of the telescopic sleeve rod 28. The top of the telescopic sleeve rod 28 extends into the inner wall of the deflection rod 24 and slides in connection with the inner wall of the deflection rod 24.

[0041] In this embodiment, by setting up a drive mechanism 20, the brake motor 22 can drive the cam 23 to rotate and the automatic rebound of the spring attached to the telescopic sleeve 28 can cause the deflection rod 24 to rotate in a meandering manner. This causes the deflection rod 24 to drive the push rod 18 to move automatically inside the slide rail 17, so that the installation process of the meter and the connection pipe 3 is an automated process, thereby avoiding manual installation and making the installation of the meter more convenient.

[0042] The working principle and usage process of this invention are as follows: When in use, first insert the two access pipes 3 into the interiors of the two mounting mechanisms 2 respectively, then start the drive mechanism 20, so that the brake motor 22 starts to rotate, causing the brake motor 22 to drive the cam 23 to rotate, so that the cam 23 starts to squeeze the contact wheel 27. At the same time, the telescopic sleeve 28 is squeezed when the deflection rod 24 rotates, so that the automatic rebound of the spring on the telescopic sleeve 28 will give the deflection rod 24 a certain reaction force, causing the deflection rod 24 to perform a meandering deflection motion, so that the deflection rod 24 drives the push rod 18 to move synchronously inside the directional groove 26.

[0043] As the push rod 18 moves, it causes the movable ring 11 to rotate, so that the squeezing block 15 gradually engages with the roller 16 on the outside of the movable rod 7. As the movable ring 11 rotates, the squeezing block 15 gradually pushes the movable rod 7 into the inside of the fixed ring 5, so that the three clamping plates 8 on the inside of the same fixed ring 5 clamp the inlet tube 3, thus completing the connection between the metering surface body and the two inlet tubes 3.

[0044] In summary, this convenient and easy-to-install flow meter device, through the installation mechanism 2, utilizes the rotatable movable ring 11 to drive the pressing block 15 to gradually contact the movable rod 7, causing the movable rod 7 to drive the clamping plate 8 to effectively clamp the inlet pipe 3 located in the fixed ring 5. This allows the meter body 1 to connect the two inlet pipes 3 through the installation mechanism 2, and the entire installation process does not use bolt and nut connections, thus avoiding the inconvenience of bolt and nut installation, making the meter installation more convenient and providing many benefits to the staff for installation and daily maintenance. Through the drive mechanism 20, the brake motor 22 can drive the cam 23 to rotate and the automatic rebound of the spring attached to the telescopic sleeve 28 can cause the deflection rod 24 to rotate in a meandering manner, causing the deflection rod 24 to drive the push rod 18 to move automatically inside the slide rail 17. This makes the installation process of the meter and the inlet pipe 3 an automated process, thus avoiding manual installation and making the meter installation more convenient.
