Description

Technical Field

[0001] This utility model relates to the technical field of water meter connection equipment, and in particular to a quick-connect fitting for water meters. Background Technology

[0002] In water supply systems, water meters are key devices for measuring water usage, and their connection method with the water supply pipeline directly affects the installation efficiency, sealing performance, and ease of maintenance of the entire system. Traditional water meter connection methods mainly include threaded connections, welded connections, and flange connections, but these methods have many limitations in practical applications.

[0003] However, in existing technologies, common water meter connection methods mostly use threaded connections, flange connections, or thermofusion connections. Threaded connections are cumbersome to install, requiring the use of specialized tools for tightening, and are prone to leakage due to thread wear or aging of the sealing tape. Flange connections have a complex structure with many parts, resulting in high installation costs, large space requirements, and low installation efficiency. Thermofusion connections require highly skilled operators, involve heating during the connection process, pose certain safety hazards, and once connected, subsequent maintenance and replacement of the water meter are extremely inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a quick-connect fitting for water meters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect fitting for a water meter, comprising a connector body, a water meter connecting pipe, and a pipeline connecting pipe. A first sealing ring is fixedly installed inside the connector body and near the edges of both side walls. A second sealing ring is provided at one end of each of the two sets of first sealing rings. A quick-release mechanism is provided at both ends of the connector body, and a reinforcement mechanism is provided at one end of each quick-release mechanism.

[0006] The quick-release mechanism includes two sets of annular seats. Two sets of limiting blocks are fixedly installed on the outer walls of the water meter connecting pipe and the pipe connecting pipe. Annular grooves are opened on the inner walls of both sets of annular seats. A convex groove is opened at the bottom of the inner end of the annular groove. A convex block is slidably installed inside the convex groove of each set. A blocking block is slidably installed inside the annular groove of each set. Two sets of vertical holes are opened through one end of both sets of annular seats.

[0007] Preferably, the inner walls of both sets of annular seats are fixed to the outer wall of the connector body, and the protruding ends of the four sets of convex blocks are respectively fixed to one end of the four sets of blocking blocks.

[0008] Preferably, the four sets of limiting blocks are respectively disposed inside the two sets of annular grooves.

[0009] Preferably, a portion of both the water meter connecting pipe and the pipeline connecting pipe are located at both ends of the connector body, and the other ends of the two sets of No. 2 sealing rings are respectively fixed to one end of the water meter connecting pipe and the pipeline connecting pipe.

[0010] Preferably, the reinforcement mechanism includes multiple sets of cylinders and annular plates. One end of each set of cylinders is inserted through a limit post, and one end of each set of limit posts is fixedly installed with a support spring. The other end of each set of cylinders is inserted through a pull rod, and one end of each set of limit blocks and two sets of annular plates is provided with three sets of limit holes.

[0011] Preferably, one end of each of the multiple sets of cylinders is fixed to the other end of each of the two sets of annular seats, and one end of each of the multiple sets of limiting posts passes through the interior of multiple limiting holes at the other end of each of the two sets of annular seats, and each contacts one end of each of the four sets of blocking blocks.

[0012] Preferably, both sets of the annular plates are sleeved on the outer wall of the connector body, the other ends of the multiple sets of support springs are respectively fixed to the inner ends of the multiple sets of cylinders, and the other ends of the multiple sets of pull rods are respectively fixed to one end of the two sets of annular plates.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, through the unique design of the quick-release mechanism, when the water meter connecting pipe and the pipeline connecting pipe are inserted into the connector body, the cooperation of the limiting block, the annular groove and the blocking block can achieve quick positioning and initial connection without complicated tools. Compared with traditional threaded connection or flange connection, it greatly shortens the installation time and significantly improves construction efficiency. When disassembling, it is only necessary to reverse the operation to easily separate the components, which facilitates the inspection and replacement of the water meter and reduces maintenance time and cost.

[0015] 2. In this utility model, the No. 1 sealing ring and the No. 2 sealing ring inside the connector body form a double sealing structure. The No. 1 sealing ring forms the first sealing line inside the connector body, and the No. 2 sealing ring fits tightly with the water meter connecting pipe and the pipeline connecting pipe to form the second seal. The double protection effectively prevents water leakage. Even under large water pressure fluctuations, it can maintain good sealing performance, ensure the stable operation of the water supply system, and avoid water waste and facility damage caused by water leakage.

[0016] 3. In this utility model, the reinforcement mechanism makes the connection more stable. After the initial quick connection is completed, by pulling the ring plate, the limiting post is driven to press tightly against the blocking block. With the elastic force of the support spring, the water meter connecting pipe, the pipe connecting pipe and the connector body are firmly fixed together. This reinforcement method can effectively resist the impact of water flow impact, external vibration and other factors on the connection part, prevent the connection from loosening or falling off, extend the service life of the pipe fittings, and ensure the long-term stable and reliable operation of the water supply system.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a quick-connect fitting for water meters, including a connector body 1, a water meter connecting pipe 13, and a pipe connecting pipe 14. A first sealing ring 11 is fixedly installed inside the connector body 1 and near the edge of both side walls. A second sealing ring 12 is provided at one end of each of the two sets of first sealing rings 11. A quick-release mechanism 2 is provided at both ends of the connector body 1, and a reinforcing mechanism 3 is provided at one end of each quick-release mechanism 2.

[0025] The quick-release mechanism 2 includes two sets of annular seats 21. Two sets of limiting blocks 22 are fixedly installed on the outer walls of the water meter connecting pipe 13 and the pipe connecting pipe 14. Annular grooves 23 are opened on the inner walls of the two sets of annular seats 21. A convex groove 24 is opened at the bottom of the inner end of the annular groove 23. A convex block 25 is slidably installed inside each convex groove 24. A blocking block 26 is slidably installed inside each annular groove 23. Two sets of vertical holes 27 are opened through one end of each set of annular seats 21. The inner walls of the two sets of annular seats 21 are fixed to the outer wall of the connector body 1. The protruding ends of the four sets of convex blocks 25 are respectively fixed to one end of the four sets of blocking blocks 26. The four sets of limiting blocks 22 are respectively set inside the two sets of annular grooves 23.

[0026] A portion of the water meter connecting pipe 13 and the pipe connecting pipe 14 are both located at both ends of the connector body 1, and the other ends of the two sets of No. 2 sealing rings 12 are respectively fixed to one end of the water meter connecting pipe 13 and the pipe connecting pipe 14.

[0027] The specific settings and functions of this embodiment are described below. The connector body 1 is a hollow tube and is the core connecting component of the pipe fitting. Inside the connector body 1 and near the edges of both side walls, a first sealing ring 11 is fixedly installed by high-precision injection molding or hot pressing. The first sealing ring 11 is made of water-resistant and aging-resistant rubber material, which has good elasticity and sealing performance. At one end of each of the two sets of first sealing rings 11, a second sealing ring 12 is provided. The second sealing ring 12 is also made of high-quality sealing material. Its structural design complements that of the first sealing ring 11, further enhancing the sealing effect. Parts of the water meter connecting pipe 13 and the pipe connecting pipe 14 are respectively inserted into the two ends of the connector body 1, and the other ends of the two sets of second sealing rings 12 are respectively fixedly connected to one end of the water meter connecting pipe 13 and the pipe connecting pipe 14 by adhesive bonding or hot vulcanization process to ensure the reliability of the seal. The water meter connecting pipe 13 and the pipe connecting pipe 14 are pre-connected to the water meter connecting end and the pipe connecting end by threading or welding.

[0028] Two sets of limiting blocks 22 are fixedly installed on the outer walls of the water meter connecting pipe 13 and the pipe connecting pipe 14. Circular grooves 23 are formed on the inner walls of both sets of annular seats 21. These grooves accommodate the limiting blocks 22 and guide their sliding. A convex groove 24 is formed at the bottom of the inner end of each annular groove 23. A convex block 25 is slidably installed inside each convex groove 24. The design of the convex block 25 and the convex groove 24 restricts the movement direction of the convex block 25, allowing it to slide only along the length of the convex groove 24. A blocking block 26 is slidably installed inside each annular groove 23. Two sets of vertical holes 27 are formed through one end of each set of annular seats 21, facilitating the insertion of four sets of limiting blocks 22 into the interior of the two sets of annular grooves 23 through the four sets of vertical holes 27. The inner wall of connector 1 is fixed to the outer wall of connector 1 by welding, threaded connection or interference fit. The protruding ends of four sets of convex blocks 25 are fixed to one end of four sets of blocking blocks 26 by welding or bolting. Four sets of limiting blocks 22 are respectively set inside the two sets of annular grooves 23. When connection is required, water meter connecting pipe 13 and pipe connecting pipe 14 are inserted into connector 1. The limiting block 22 slides into the annular groove 23 through the vertical hole 27. The blocking block 26 is rotated to move, so that the convex block 25 rotates in the convex groove 24. The convex block 25 will push the blocking block 26 to move together in the annular groove 23. When the limiting block 22 reaches the predetermined position, the cooperation of the two sets of annular seats 21 and the two sets of annular grooves 23 will lock the limiting block 22, realizing the initial quick connection.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the reinforcing mechanism 3 includes multiple sets of cylinders 31 and annular plates 33. One end of each set of cylinders 31 is inserted through a limit post 32, and one end of each set of limit posts 32 is fixedly mounted with a support spring 34. The other end of each set of cylinders 31 is inserted through a pull rod 35. Each set of limit blocks 22 and one end of each set of annular seats 21 are provided with three sets of limit holes 36. One end of each set of cylinders 31 is fixed to the other end of each set of annular seats 21. One end of each set of limit posts 32 passes through the interior of the multiple sets of limit holes 36 at the other end of each set of annular seats 21 and contacts one end of each set of four blocking blocks 26. The two sets of annular plates 33 are sleeved on the outer wall of the connector body 1. The other end of each set of support springs 34 is fixed to the inner end of each set of cylinders 31. The other end of each set of pull rods 35 is fixed to one end of each set of annular plates 33.

[0030] The overall effect of this embodiment is that the reinforcing mechanism 3 further enhances the stability of the connection. Multiple sets of cylinders 31 are evenly distributed along the circumference of the annular seat 21. One end of each set of cylinders 31 is penetrated by a limiting post 32. A support spring 34 is fixedly installed at one end of the limiting post 32. The support spring 34 is a high-strength spring with good elastic restoring force. A pull rod 35 is penetrated at the other end of each set of cylinders 31. Three sets of limiting holes 36 are opened at one end of each set of limiting blocks 22 and two sets of annular seats 21. One end of each set of cylinders 31 is fixed to one end of each set of annular seats 21 by welding or threaded connection. One end of each set of limiting posts 32 passes through the interior of the multiple sets of limiting holes 36 at the other end of each set of annular seats 21 and contacts one end of each of the four sets of blocking blocks 26. Two sets of annular plates 33 are sleeved on the outer wall of the connector body 1 and can move along the connector body. The outer wall of 1 slides, and the other end of multiple sets of support springs 34 is fixed to the inner end of multiple sets of cylinders 31 respectively. The other end of multiple sets of tie rods 35 is fixed to one end of two sets of annular plates 33 by welding or bolt connection. After the initial connection is completed, the limiting post 32 presses tightly against the blocking block 26 under the action of the support spring 34. When the two sets of limiting blocks 22 move to the multiple sets of limiting posts 32 and the multiple sets of limiting holes 36 are aligned with the limiting post 32, the support spring 34 will push the limiting post 32 to move, so that the limiting post 32 is inserted into the interior of the limiting hole 36, further strengthening the connection and preventing the limiting block 22 from loosening. Conversely, pulling the annular plate 33, the annular plate 33 drives the limiting post 32 to move through multiple sets of screw tie rods 35, so that the multiple sets of limiting posts 32 are moved out from the interior of the multiple sets of limiting holes 36, which can release the fixing of the limiting block 22 and facilitate the disassembly of the limiting block 22.

[0031] The usage method and working principle of this device are as follows: When performing the connection operation, the water meter connecting pipe 13 and the pipe connecting pipe 14 are respectively aligned with the two ends of the connector body 1 and inserted. At this time, the limiting block 22, which is fixedly installed on the outer wall of the water meter connecting pipe 13 and the pipe connecting pipe 14, begins to enter the annular groove 23 on the inner wall of the annular seat 21 through the vertical hole 27. Then, the limiting block 22 is rotated, which causes the blocking block 26 to move along the annular groove 23. Since the blocking block 26 is fixedly connected to the convex block 25, the convex block 25 also slides in the convex groove 24.

[0032] As the water meter connecting pipe 13 and the pipe connecting pipe 14 are continuously inserted, when the limiting block 22 reaches the predetermined position, the limiting block 22 is limited inside the annular seat 21 by two sets of blocking blocks 26, thus realizing the initial rapid connection between the water meter connecting pipe 13, the pipe connecting pipe 14 and the connector body 1.

[0033] Finally, after the initial connection is completed, under the elastic force of multiple sets of support springs 34, the support springs 34 will push the limiting post 32 to move, so that the limiting post 32 is inserted into the interior of the limiting hole 36, further strengthening the connection and preventing the limiting block 22 from loosening.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
