[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. When using a water meter, both ends of the water meter need to be connected to the water pipe, and a clamp is required for the connection. A clamp is a connection device for connecting grooved pipes, valves, and pipe accessories. It is used to tighten the connection between quick connectors. Generally, the connector has gaskets, rubber, silicone, and PTFE. The clamp can be used to fix the water meter and the water pipe, thereby enabling the circulation of water and facilitating the measurement of water flow through the water meter.

[0025] Furthermore, the disassembly and assembly mechanism also includes a fixing rod 22, which is fixedly connected to one end of the first joint 12 away from the first clamp 1, and a first plug rod 23 is movably connected to the inner side of the fixing rod 22. A first spring 25 is fixedly connected to the surface of the first plug rod 23, and a second plug rod 26 is movably connected to the inner side of the fixing rod 22. A second slot 27 is provided on the surface of the first plug rod 23, and a third slot 28 is provided on the surface of the first plug rod 23. A second spring 29 is fixedly connected to the surface of the second plug rod 26, and the second plug rod 26 is movably connected to the inner side of the fixing rod 22. By engaging the second plug rod 26 with the second slot 27 or the third slot 28, the first plug rod 23 can be limited, so that the first plug rod 23 is not easy to slip.

[0026] Furthermore, the mounting blocks 2 are in two groups and connected correspondingly to the second joint 15, the mounting grooves 21 are in two groups and connected correspondingly to the first joint 12, the first plug rod 23 is in a rod-shaped movably connected to the inner side of the first joint 12, and the first plug rod 23 is movably connected to the inner side of the first joint 12. Through the engagement and separation of the first plug rod 23 and the first slot 24, it is convenient to fix and remove the first clamp 1 and the second clamp 13, and then the water meter and the water pipe can be quickly connected and disassembled.

[0027] Furthermore, one end of the first spring 25 is fixedly connected to the first joint 12, the other end of the first spring 25 is fixedly connected to the first plug rod 23, the second plug rod 26 is movably connected to the fixed rod 22 in two groups, one end of the second spring 29 is fixedly connected to the fixed rod 22, and the other end of the second spring 29 is fixedly connected to the second plug rod 26.

[0028] Furthermore, a positioning mechanism is provided on the inner side of the first joint 12, and the positioning mechanism includes a positioning rod 3, which is fixedly connected to the surface of the first joint 12, a positioning groove 31 is provided on the inner side of the second joint 15, and a movable groove 32 is provided on the surface of the positioning rod 3, and a third spring 33 is fixedly connected to the inner wall of the movable groove 32, and a clamping block 34 is fixedly connected to the end of the third spring 33 away from the movable groove 32, and the positioning rod 3 is fixedly connected to the surface of the first joint 12. Through the cooperation of the positioning rod 3 and the positioning groove 31, the first clamp 1 and the second clamp 13 can be positioned, and the first clamp 1 and the second clamp 13 can be prevented from being offset when fixed, thereby affecting the installation effect of the water meter and the water pipe.

[0029] Furthermore, the positioning rods 3 are formed into four groups and fixedly connected to the first joint 12, the positioning grooves 31 are formed into four groups and are opened on the surface of the second joint 15, the clamping block 34 is formed into an arc shape and fixedly connected to the third spring 33, and the clamping block 34 and the third spring 33 are fixedly connected.

[0030] Working principle: When in use, the second plug rod 26 is pulled outward, at this time the second spring 29 is in a contracted state, and then the first plug rod 23 is pulled outward, so that the first plug rod 23 moves to the outside of the first joint 12, and the first spring 25 is in a contracted state. By loosening the second plug rod 26, the second plug rod 26 is inserted into the inner side of the third slot 28 under the rebound action of the second spring 29, so as to limit the first plug rod 23, and then the water meter and the water pipe are connected, and the first clamp 1 and the second clamp 13 are sleeved on the surface of the water meter and the water pipe, and the mounting block 2 is inserted into the inner side of the mounting groove 21, and then the second plug rod 26 is pulled out to separate the second plug rod 26 and the third slot 28, and then The first plug rod 23 is inserted into the inner side of the first slot 24 under the rebound action of the first spring 25 to lock the mounting block 2, and then the second plug rod 26 is inserted into the inner side of the second slot 27 through the rebound action of the second spring 29 to limit the first plug rod 23, so that the first clamp 1 and the second clamp 13 can be fixed, thereby realizing the installation of the water meter and the water pipe; when it needs to be removed, the second plug rod 26 is pulled out to separate the second plug rod 26 from the second slot 27, the limitation of the first plug rod 23 is released, and then the first plug rod 23 is pulled out to separate the first plug rod 23 and the first slot 24, and then the first clamp 1 and the second clamp 13 are pulled to separate the mounting block 2 and the mounting groove 21.

[0031] When fixing the first clamp 1 and the second clamp 13, the first joint 12 and the second joint 15 are in contact, and the positioning rod 3 and the positioning groove 31 are aligned and inserted. When the clamp block 34 contacts the inner wall of the positioning groove 31, it will move toward the inner side of the movable groove 32 due to compression. At this time, the third spring 33 is deformed. At the same time, the resilience of the third spring 33 can make the clamp block 34 and the inner wall of the positioning groove 31 fit together, thereby realizing the fixing and positioning of the first clamp 1 and the second clamp 13.
