[0002] A water meter is a metering tool used to measure and record the flow of water through a closed pipe. It plays a vital role in water resource management and water supply systems.

[0003] Water meters are usually installed deep in water pipes or in narrow spaces, making the disassembly and assembly process difficult, which not only increases the difficulty of repairing and replacing water meters, but also increases the maintenance cost of the water supply system. In order to solve the problem of inconvenient disassembly and assembly, many people have designed water meters that are easy to disassemble and assemble, such as the patent number: 202222949752.5, the patent name: A utility model patent for a smart water meter that is easy to disassemble and assemble. By setting a card slot, a card block, a pin rod and a plug hole, quick disassembly and assembly can be achieved, saving the workload of the operator. However, the sealing performance is poor during actual use, and water leakage often occurs. Therefore, it is necessary to consider quick disassembly and assembly while ensuring the sealing of the water pipe connection during design. Summary of the invention

[0004] To solve the above problems, the present application provides a water meter that can be quickly disassembled and assembled, comprising a water meter body and a connecting pipe, the water meter body being provided with a water inlet pipe and a water outlet pipe, the connecting pipe and the water inlet pipe being provided with matching locking units, the locking unit comprising a locking protrusion and a sealing ring arranged on the connecting pipe, the sealing ring being located on a side close to the connecting pipe port, the water inlet pipe being provided with a locking groove and an annular boss, the locking groove being located on a side close to the water inlet pipe port.

[0005] In one embodiment, the sealing ring includes a first sealing ring and a second sealing ring, a separation ring is arranged between the first sealing ring and the second sealing ring, the annular boss includes a first annular boss and a second annular boss, the first sealing ring matches the first annular boss, and the second sealing ring matches the second annular boss.

[0006] In one embodiment, the locking protrusion is in a barb shape, and the tail of the locking protrusion is raised.

[0007] In one embodiment, the side wall of the locking groove is sloped.

[0008] In one embodiment, an annular baffle is provided on a side of the separation ring close to the second sealing ring, and the annular baffle can be snapped onto the second annular boss.

[0009] The beneficial effects of the utility model are:

[0010] The present application provides a water meter that can be quickly disassembled and assembled. By providing a locking protrusion and a locking groove, the locking protrusion is stuck in the locking groove to form a stable mechanical lock. During installation, the connection between the connecting pipe and the water inlet pipe can be completed through a simple pushing action without using any tools, which greatly speeds up the installation speed and allows easy operation. By providing a sealing ring and an annular boss, when the connecting pipe is pushed into place, the sealing ring will be squeezed on the annular boss, thereby achieving the sealing of the water path.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] like Figure 1-5 As shown, a water meter that can be quickly disassembled and assembled is provided with a water meter body 1 and a connecting pipe 2, the water meter body 1 is provided with a water inlet pipe 3 and a water outlet pipe 4, the connecting pipe 2 and the water inlet pipe 3 are provided with matching locking units 5, the locking unit 5 includes a locking protrusion 51 and a sealing ring 52 arranged on the connecting pipe 2, the sealing ring 52 is located on the side close to the port of the connecting pipe 2, the water inlet pipe 3 is provided with a locking groove 53 and an annular boss 54, the locking groove 53 is located on the side close to the port of the water inlet pipe 3.

[0029] Specifically, when the connecting pipe 2 needs to be installed on the water inlet pipe 3 of the water meter body 1, align the port of the connecting pipe 2 with the port of the water inlet pipe 3, align the locking protrusion 51 with the locking groove 53, and in the process of continuing to push in, the locking protrusion 51 will be stuck in the locking groove 53, forming a stable mechanical lock. At the same time, since a sealing ring 52 is provided at the port of the connecting pipe 2, and an annular boss 54 is provided on the water inlet pipe 3, the sealing ring 52 is located on the side close to the port of the connecting pipe 2, and the outer diameter of the locking protrusion 51 is larger than the outer diameter of the sealing ring 52, the locking protrusion 51 can play a role in supporting the sealing ring 52. When the connecting pipe 2 is pushed into place, the sealing ring 52 will be squeezed on the annular boss 54, thereby achieving the sealing of the waterway; this design ensures both the stability of the connection and the sealing, and avoids the occurrence of water leakage; the connection between the connecting pipe and the water inlet pipe can be completed by a simple pushing action, without the use of any tools, which greatly speeds up the installation speed and can be easily operated; the use of the sealing ring and the annular boss ensures the sealing of the waterway at the connection, effectively preventing the occurrence of water leakage. The locking unit 5 can also be located at the position of the connecting pipe 2 and the water outlet pipe 5.

[0030] like Figure 2-6As shown, in order to ensure the sealing performance, the sealing ring 52 includes a first sealing ring 521 and a second sealing ring 522, a separation ring 523 is arranged between the first sealing ring 521 and the second sealing ring 522, and the annular boss 54 includes a first annular boss 541 and a second annular boss 542, the first sealing ring 521 matches the first annular boss 541, and the second sealing ring 522 matches the second annular boss 542.

[0031] Specifically, the sealing performance is improved by a double sealing structure, that is, the first sealing ring 521 and the second sealing ring 522 on the connecting pipe 2 will correspond to and be squeezed onto the first annular boss 541 and the second annular boss 542 on the water inlet pipe 3. The first annular boss 541 and the second annular boss 542 provide a stable extrusion surface for the sealing ring 52, so that the first sealing ring 521 and the second sealing ring 522 can be closely fitted on the first annular boss 541 and the second annular boss 542, respectively, to form two independent sealing lines, thereby improving the reliability of the seal and reducing the risk of water leakage. A separation ring 523 is provided between the first sealing ring 521 and the second sealing ring 522 to ensure that the first sealing ring 521 and the second sealing ring 522 can act independently when under pressure, avoid mutual interference, and enable each sealing ring 52 to give full play to its sealing performance, further improving the sealing effect. In this embodiment, a double sealing structure is used, and the water meter realizes double sealing protection. Without falling off the concept of this embodiment, the use of a three-layer or multi-layer sealing structure is also within the scope of protection of this application.

[0032] like Figure 2 , 3 As shown, the locking protrusion 51 is in a barb shape, and the tail of the locking protrusion 51 is tilted.

[0033] Specifically, since the locking protrusion 51 is in the shape of a barb and the tail is tilted, when the connecting pipe 2 is gradually pushed into the water inlet pipe 3, the tail of the locking protrusion 51 will first contact the inner wall of the water inlet pipe 3, and the tail of the locking protrusion 51 will be compressed, causing it to be temporarily flattened or deformed inward; as the connecting pipe 2 continues to be pushed in, when the locking protrusion 51 reaches the position corresponding to the locking groove 53 on the water inlet pipe 3, the tail of the locking protrusion 51 will naturally restore its tilted state due to the lack of pressure from the inner wall of the water inlet pipe. At this time, the tail of the locking protrusion 51 will be stuck in the locking groove 53, thereby achieving the locking between the connecting pipe 2 and the water inlet pipe 3. By setting the locking protrusion 51 and the locking groove 53, rapid locking can be achieved without the need for additional operations or tools, forming a stable mechanical lock, and ensuring the stability and convenience of the connection.

[0034] like Figure 4 As shown, the side wall of the locking groove 53 is sloped.

[0035] Specifically, during the disassembly process, the connecting tube 2 is rotated. Since the side wall of the locking groove 53 is sloped, as the connecting tube 2 rotates, the tail of the locking protrusion 51 is guided and compressed by the slope, gradually slides along the slope, and finally escapes from the constraint of the locking groove 53. The sloped design of the locking groove 53 makes the disassembly process simpler and faster, and the disassembly can be easily achieved without using additional tools or applying excessive force.

[0036] like Figure 2 , 6 As shown, an annular baffle 524 is provided on one side of the separation ring 523 close to the second sealing ring 522 , and the annular baffle 524 can be snapped onto the second annular boss 542 .

[0037] Specifically, the annular baffle 524 is used to cooperate with the second annular boss 542. The annular baffle 524 can be snapped onto the second annular boss 542 to ensure that the separation ring 523 is accurately positioned. In addition, when the annular baffle 524 is snapped onto the second annular boss 542, the second sealing ring 522 is squeezed onto the annular baffle 524, and the sealing effect is better.

[0038] The present application provides a water meter that can be quickly disassembled and assembled. By setting a locking protrusion 51 and a locking groove 53, the locking protrusion 51 is stuck in the locking groove 53 to form a stable mechanical lock. During installation, the connection between the connecting pipe 2 and the water inlet pipe 3 can be completed by a simple pushing action without using any tools, which greatly speeds up the installation speed and allows easy operation. By setting a sealing ring 52 and annular boss 54, when the connecting pipe 2 is pushed into place, the sealing ring 52 will be squeezed on the annular boss 54, thereby achieving the sealing of the water path. The coordinated use of the sealing ring 52 and the annular boss 54 ensures the sealing of the water path at the connection, effectively preventing the occurrence of water leakage. The present application not only achieves the rapid disassembly and assembly of the water meter and the connecting pipe, but also improves the sealing effect of the connection.
