Obviously, the specific implementation mode described is only a part of the implementation mode of the utility model, rather than all styles.

[0032] Embodiment 1:

[0033] See also Figure 1 and Figure 4 The utility model provides a technical solution: an electromagnetic water meter sealing structure, including a water meter body 1, one end of the water meter body 1 is a water inlet end 2, and the other end is a water outlet end 3; a measuring tube 4 is connected inside the water meter body 1, and the measuring tube 4 cooperates with the water body of the water meter; both ends of the measuring tube 4 are connected to a first annular sleeve 5, and the other sides of the two first annular sleeves 5 are connected to a water delivery hose 6 with an inner diameter that can be expanded; the other ends of the two water delivery hoses 6 are connected to a second annular sleeve 8; the water delivery hose 6 cooperates with the first annular sleeve 5 and the second annular sleeve 8 respectively; the water inlet end 2 and the water outlet end 3 of the water meter body 1 are connected to an annular seat 11, and the two annular seats 11 are provided with mounting sleeves 14.

[0034] Specifically, a plurality of "ring-shaped" support blocks 7 are provided on the two water hoses 6 to provide support when the inner diameter of the water hose 6 is expanded during water delivery. The inner walls of the two water hoses 6 are connected with a plurality of guide plates 9, and the plurality of guide plates 9 are evenly distributed on the water hose 6. The other sides of the two second annular sleeves 8 are connected with fixed rings 10, and cooperate with the measuring tube 4 to keep the water hose 6 in an extended state. By adopting the above technical solution, the water hose 6 is supported by the support blocks 7 during the water delivery operation. When the water hose 6 is propped up, it can fit the inner wall of the pipeline to provide support, thereby achieving a sealing effect. The water flow is blocked by the guide plates 9, so that the inner diameter of the water hose 6 can be smoothly propped up. The fixed ring 10 is used in cooperation with the water hose 6 to allow the water flow in the pipeline to smoothly enter the water hose 6.

[0035] Embodiment 2:

[0036] Based on Example 1, please refer to Figure 2 and Figure 3 .

[0037] Specifically, the surfaces of the two annular seats 11 are provided with external threads 12, and the inner walls of the two mounting sleeves 14 are provided with internal threads 15, the external threads 12 cooperate with the internal threads 15, and the mounting sleeves 14 are threadedly connected to the annular seats 11, and the other sides of the two annular seats 11 are connected to multiple clamping plates 13, and the multiple clamping plates 13 are evenly distributed on the annular seats 11, and the multiple clamping plates 13 are all inclined 30 degrees away from the water meter body 1, and one side of the two mounting sleeves 14 is connected to a fixing sleeve 16, and the mounting sleeve 14 is a trapezoidal cylindrical shape, and the fixing sleeve 16 on one side of the mounting sleeve 14 cooperates with the clamping plate 13 on one side of the annular seat 11, and the inner walls of the two annular seats 11 are connected to sealing gaskets 17. By adopting the above technical solution, the installation sleeve 14 is screwed on the annular seat 11 so that the installation sleeve 14 is gradually sleeved on the annular seat 11, and due to the special structure of the installation sleeve 14, when the component is sleeved on the annular seat 11, the internal clamping plate 13 is pushed close to the outer surface of the pipe. In the process of gradual screwing, the clamping plate 13 fits the surface of the pipe, clamps the pipe and limits it, which is convenient for use. The sealing gasket 17 contacts the end of the pipe to be inserted, thereby assisting the sealing operation.

[0038] The working principle of the utility model is as follows: when in use, the staff places the water meter body 1 between two pipes, first sleeves the fixing sleeve 16 on the water outlet pipe, aligns one end of the installation sleeve 14 with the water inlet end 2 of the water meter body 1, puts the fixing ring 10 at one end of the measuring tube 4 of the water inlet end 2 of the water meter body 1 into the pipe, and pushes the water meter body 1 to make the water delivery hose 6 smoothly enter the pipe until the pipe passes between a plurality of clamping plates 13 and enters the annular seat 11. After one end of the pipe contacts the sealing gasket 17, the movement stops. The staff can align the installation sleeve 14 with the annular seat 11, and screw the installation sleeve 14 so that the internal thread 15 on the inner wall of the installation sleeve 14 meshes and rotates on the external thread 12 on the surface of the annular seat 11, so that the installation sleeve 14 is in the annular seat 1 1 is rotated to approach the water meter body 1. In the process of gradually approaching, due to the special shape of the installation sleeve 14, the multiple clamping plates 13 are moved inward until the fixing sleeve 16 on one side of the installation sleeve 14 is close to the clamping plate 13, thereby expanding the clamping range of the clamping plate 13. When the screwing is continuously turned, the multiple clamping plates 13 are close to the outer surface of the pipe inserted into the annular seat 11. The multiple clamping plates 13 are close to the pipe surface, thereby clamping and fixing the pipe to prevent the pipe from falling off during use. After the clamping plate 13 is completely attached to the pipe and limited, the installation sleeve 14 is no longer screwed, thereby avoiding the situation of connecting the water meter and the pipe by bolts in the traditional way. The same is true for the other end. The above steps are repeated to install one end of the other pipe on the water outlet end 3 of the water meter body 1.

[0039] When delivering water, the fixing ring 10 is located in the pipeline, and the fixing ring 10 and the measuring tube 4 provide support for the water hose 6, so that the water hose 6 remains in an extended state, and due to the multiple support blocks 7 arranged on the water hose 6, when the water in the pipeline is released, it will pass through the fixing ring 10 and enter the water hose 6, and the water pressure entering the water hose 6 is increased by blocking the guide plate 9 arranged on the inner wall of the water hose 6, so that the water hose 6 is slightly propped up, so that the outer surface of the water hose 6 contacts the inner wall of the pipeline, and the sealing gasket 17 in contact with one end of the pipeline cooperates to make the connection and sealing effect of the water meter body 1 and the pipeline better.
