[0002] As an important instrument for measuring water flow, water meters are widely used in fields such as households, industries, and agriculture. In order to ensure that water can flow accurately through the water meter for measurement, the connection between the water meter and the water pipe must be firm and well-sealed.

[0003] In the prior art, the water meter needs to be connected to the water pipes at both ends. However, in the actual building construction process, due to the uneven technical levels of construction workers, different measuring tools, etc., the laying positions of the water pipes are not precise enough. As a result, even a slight deviation in the reserved position may cause difficulties in smoothly installing the water meter. Even if the installation is smooth, there are still significant problems with the sealing performance, increasing the construction difficulty and cost. Therefore, in view of the above problems, we propose a new water meter connector structure. Summary of the Utility Model

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figures 1-4 shown, the present invention provides a water meter joint structure, including a connecting pipe 11 and an inlet pipe 3. A threaded sleeve 2 is threadedly connected to the outer surface of the connecting pipe 11 near the left side. A movable sleeve 31 is slidably connected to the outer surface of the inlet pipe 3 near the middle. A mounting sleeve 4 is threadedly connected to the outer surface of the movable sleeve 31 near the left side. A second anti-slip ring 32 is fixedly connected to the outer surface of the movable sleeve 31 near the right edge. A first anti-slip ring 21 is fixedly connected to the outer surface of the threaded sleeve 2 near the left edge. The inner wall of the threaded sleeve 2 is threadedly connected to the outer surface of the inlet pipe 3. A rubber ring 41 is fixedly connected to the outer surface of the inlet pipe 3 near the left side. The outer surface of the rubber ring 41 is not in contact with the inner wall of the mounting sleeve 4. A fixing ring 35 is fixedly connected to the outer surface of the inlet pipe 3 near the left edge. The left surface of the rubber ring 41 cooperates with the right surface of the fixing ring 35. The right surface of the rubber ring 41 cooperates with the left surface of the movable sleeve 31. A plurality of anti-slip lines are provided on the outer surfaces of the first anti-slip ring 21 and the second anti-slip ring 32. The right surface of the connecting pipe 11 is fixedly communicated with a water meter body 1. The right surface of the water meter body 1 is fixedly communicated with an outlet pipe 14.

[0023] The effect achieved by the entire Embodiment 1 is that when using this device, by aligning and inserting the right end part of the water inlet pipe 3 into the left end interior of the connecting pipe 11, and through the rotation of the threaded sleeve 2, the inner wall of the threaded sleeve 2 is tightly thread - connected to the outer surface of the water inlet pipe 3. During this process, the anti - slip pattern of the first anti - slip ring 21 increases the friction during rotation, facilitating operation and preventing slippage. Then, through the rotation of the mounting sleeve 4, the movable sleeve 31 thread - connected inside the mounting sleeve 4 moves to the left. After moving to a certain position, it will squeeze the rubber ring 41. Since the rubber ring 41 is located between the fixed ring 35 and the movable sleeve 31 and is made of nitrile rubber material, when subjected to external pressure, the rubber ring 41 made of nitrile rubber material can undergo obvious elastic deformation, thereby forming an effective sealing layer between the mounting sleeve 4 and the water inlet pipe 3 to prevent water leakage. The elasticity of the rubber ring 41 ensures that the sealing effect can be maintained even when the pressure changes. At the same time, the movable sleeve 31 is fixed on the water inlet pipe 3 through the threaded connection of the mounting sleeve 4, further stabilizing the structure of the entire joint. The joint point of the mounting sleeve 4 and the movable sleeve 31, as well as the anti - slip pattern of the second anti - slip ring 32, enhance the stability of the connection and the convenience of operation. When water flows into the water meter system through the water inlet pipe 3, it first passes through the sealing layer of the rubber ring 41, then flows into the connecting pipe 11, and then enters the water meter body 1 for metering. Finally, the metered water flows out through the outlet pipe 14 to complete the entire process. The design of the first anti - slip ring 21 and the second anti - slip ring 32 not only improves the convenience of operation during installation and disassembly but also increases the safety during use, preventing loosening or falling off caused by accidental touch or vibration. The entire water meter joint structure ensures its stability and durability in various usage environments through multi - level connection and fixation. Whether it is for daily water use or in the face of sudden high water pressure situations, it can maintain stable performance and reliable sealing effect. The entire design simplifies the installation steps, improves the installation efficiency, reduces the technical requirements for construction workers. Its multi - layer sealing structure enhances the sealing performance, effectively preventing water leakage, and at the same time reducing the construction and post - maintenance costs. In addition, this structure also improves the construction safety and avoids potential safety hazards.

[0024] Embodiment 2: As Figures 1-4 shown, a first rubber pad 12 is fixedly connected to the left surface of the connecting pipe 11, a first meshing tooth 13 is arranged on the left surface of the first rubber pad 12, a second rubber pad 33 is fixedly connected to the right surface of the water inlet pipe 3, a second meshing tooth 34 is arranged on the right surface of the second rubber pad 33, and the first meshing tooth 13 cooperates with the second meshing tooth 34.

[0025] The effect achieved by the entire Embodiment 2 is that the mutual engagement between the first engaging teeth 13 on the first rubber pad 12 and the second engaging teeth 34 on the second rubber pad 33 can make the contact between the rubber pads closer. When under pressure, the tooth-like structures can be nested with each other, forming an effect similar to a labyrinth seal, increasing the resistance path of fluid leakage, further improving the sealing performance, and providing a more reliable sealing than rubber pads with ordinary smooth surfaces.

[0026] Working principle: When using this device, the right end part of the water inlet pipe 3 is aligned with and inserted into the left end interior of the connecting pipe 11. By rotating the threaded sleeve 2, the inner wall of the threaded sleeve 2 is tightly threadedly connected to the outer surface of the water inlet pipe 3. During this process, the anti-slip lines of the first anti-slip ring 21 increase the friction during rotation, facilitating operation and preventing slipping. Then, by rotating the mounting sleeve 4, the movable sleeve 31 internally threadedly connected to the mounting sleeve 4 moves leftward. After moving to a certain position, it will squeeze the rubber ring 41. When under external pressure, the rubber ring 41 can undergo obvious elastic deformation, thereby deforming to form an effective sealing layer between the mounting sleeve 4 and the water inlet pipe 3 to prevent water leakage. At the same time, the movable sleeve 31 is fixed on the water inlet pipe 3 through the threaded connection of the mounting sleeve 4, further stabilizing the structure of the entire joint. The joint point of the mounting sleeve 4 and the movable sleeve 31, as well as the anti-slip lines of the second anti-slip ring 32, enhance the connection stability and operation convenience. When water flows through the water inlet pipe 3 into the water meter system, it first passes through the sealing layer of the rubber ring 41, then flows into the connecting pipe 11, and then enters the water meter body 1 for measurement. Finally, the measured water flows out through the outlet pipe 14 to complete the entire process. The design of the first anti-slip ring 21 and the second anti-slip ring 32 not only improves the operation convenience during installation and disassembly but also increases the safety during use, preventing loosening or falling off caused by accidental touch or vibration. The entire water meter joint structure ensures its stability and durability in various use environments through multi-level connection and fixation. Whether it is for daily water use or in the face of sudden high water pressure situations, it can maintain stable performance and reliable sealing effect. The entire design simplifies the installation steps, improves the installation efficiency, reduces the technical requirements for construction personnel. Its multiple sealing structures enhance the sealing performance, effectively prevent water leakage, and at the same time reduce the construction and post-maintenance costs. In addition, this structure also improves the construction safety and avoids potential safety hazards. Moreover, the mutual engagement between the first engaging teeth 13 on the first rubber pad 12 and the second engaging teeth 34 on the second rubber pad 33 can make the contact between the rubber pads closer. When under pressure, the tooth-like structures can be nested with each other, forming an effect similar to a labyrinth seal, increasing the resistance path of fluid leakage, further improving the sealing performance, and providing a more reliable sealing than rubber pads with ordinary smooth surfaces.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
