Description

Technical Field

[0001] This utility model relates to the field of water supply pipe technology, and in particular to a connection structure for HDPE water supply pipes. Background Technology

[0002] HDPE pipe is a type of pipe made of high-density polyethylene. During pipe installation, multiple pipe sections need to be reliably connected through a connection structure. Its sealing performance and ease of installation directly affect the operational safety and service life of the pipeline network.

[0003] Currently, common HDPE water supply pipe connection methods include heat fusion, electrofusion, and mechanical connection. However, existing mechanical connection structures still have the following problems: First, the sealing performance is insufficient, and after long-term use, leakage at the joints is prone to occur due to material aging, vibration, and other factors; second, the installation process is complex, often requiring specialized tools or multiple people to cooperate, resulting in low construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for HDPE water supply pipes, which can improve the sealing effect after the water supply pipes are connected, facilitate installation, and improve construction efficiency.

[0005] To achieve the above objectives, a connection structure for HDPE water supply pipes is provided, including two water supply pipe bodies. A connecting mechanism is installed at the opposite ends of the two water supply pipe bodies, with one end of each water supply pipe body inserted into the connecting mechanism. Each water supply pipe body comprises a fixing sleeve, a connecting plate, connecting bolts, and nuts. Two fixing sleeves are provided, located at the opposite ends of the two water supply pipe bodies, with the water supply pipe bodies extending into the fixing sleeves. The connecting plate is fixedly connected to the surface of the fixing sleeve. The connecting bolts pass through the connecting plates on both fixing sleeves in sequence, and are slidably connected to the connecting plates. The nuts are fitted onto the surface of the connecting bolts and are threadedly connected to them, ensuring tight contact between the two fixing sleeves through the connecting plates. This structure improves the sealing effect after the water supply pipe connection, facilitates installation, and increases construction efficiency.

[0006] According to the connection structure of the HDPE water supply pipe, a sealing ring is provided between the two fixed jackets. The sealing ring improves the sealing performance at the connection between the two fixed jackets.

[0007] According to the aforementioned connection structure for an HDPE water supply pipe, the fixing sleeve comprises a fixing plate, a housing, a hinge, and a locking bolt. The housing has a semi-circular arc structure and consists of two units, forming a cylindrical structure. The two housings cooperate to enclose the water supply pipe. The hinge is installed on one side of the housing, and the two housings are rotatably connected via the hinge. The fixing plate is fixedly connected to the ends of the two housings away from the hinge. A locking bolt is located in the center of the fixing plate, and the locking bolt cooperates with the fixing plate to lock the two housings. A semi-circular arc-shaped sealing gasket is embedded in the inner wall of the housing, and the sealing gasket has an interference fit with the surface of the water supply pipe. During the installation of the fixing sleeve, the hinge allows the housing to be rotated to enclose the water supply pipe, and the locking bolts are used to fix the housing.

[0008] According to the aforementioned connection structure for an HDPE water supply pipe, a limiting groove is formed at one end of the shell, and the limiting groove is located at the opposite ends of two fixed sleeves. The limiting grooves on the two shell surfaces form a ring. The sealing ring has a cross-shaped cross section, and its two ends are respectively embedded in the limiting grooves on the two fixed sleeves. The sealing ring improves the sealing effect on the water supply pipe when the shell wraps around it, and increases the friction on the shell surface, preventing the water supply pipe from detaching from the pipe body.

[0009] According to the aforementioned HDPE water supply pipe connection structure, one end of the shell is provided with a connection port, and two fixing sleeves are connected through the connection port. The end of the shell away from the connection port is provided with an installation port, and the installation port is connected to the connection port. The water supply pipe body is located in the installation port. This allows water from the water supply pipe to enter another water supply pipe through the installation port.

[0010] According to the aforementioned connection structure for an HDPE water supply pipe, the diameter of the connection port is the same as the inner diameter of the water supply pipe body, and the diameter of the installation port is the same as the outer diameter of the water supply pipe body. This reduces the resistance encountered by water flow when passing through the two fixed jackets.

[0011] According to the connection structure of the HDPE water supply pipe, the shell is made of high-density polyethylene. Using the same material as the HDPE water supply pipe, it possesses resistance to chemical corrosion, aging, and wear.

[0012] According to the connection structure of the HDPE water supply pipe, the inner wall of the shell is provided with anti-slip patterns. This increases the friction of the inner wall of the shell and improves the fixing effect of the shell on the water supply pipe.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. By rotating the housing around the hinge, the fixing sleeves are respectively installed to the connection ends of the two water supply pipes. The connecting bolts are used to fix the housing and to tightly connect the two fixing sleeves, thereby completing the connection of the water supply pipes. This allows the connection of the water supply pipes to be operated by a single person, making installation convenient.

[0015] 2. The sealing effect between the fixed jacket and the water supply pipe is improved by the sealing gasket, the sealing ring improves the sealing effect at the connection of the two fixed jackets, and the groove limits the sealing ring to prevent the sealing ring from shifting due to vibration and causing water leakage at the interface.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5 This utility model discloses a connection structure for an HDPE water supply pipe, comprising a water supply pipe body 1, of which two water supply pipe bodies 1 are provided. A connection mechanism 2 is installed at the opposite ends of the two water supply pipe bodies 1, and one end of the water supply pipe body 1 is inserted into the connection mechanism 2. The water supply pipe body 1 is composed of a fixing sleeve 3, a connecting plate 4, a connecting bolt 5, and a nut 7. There are two fixing sleeves 3, which are respectively located at the opposite ends of the two water supply pipe bodies 1, and the water supply pipe body 1 extends into the fixing sleeve 3. The connecting plate 4 is fixedly connected to the surface of the fixing sleeve 3. The connecting bolt 5 passes through the connecting plate 4 on the two fixing sleeves 3 in sequence, and the connecting bolt 5 is slidably connected to the connecting plate 4. The nut 7 is sleeved on the surface of the connecting bolt 5 and threadedly connected to the connecting bolt 5. The nut 7 cooperates with the bolt to make the two fixing sleeves 3 in close contact through the connecting plate 4.

[0027] A sealing ring 6 is provided between the two fixed sleeves 3. The sealing ring 6 improves the sealing performance at the connection between the two fixed sleeves 3.

[0028] The fixing sleeve 3 consists of a fixing plate 8, a housing 9, a hinge 10, and a locking bolt 11. The housing 9 has a semi-circular arc structure and two housings are provided, forming a cylindrical structure. The two housings 9 cooperate to wrap around the water supply pipe 1. The hinge 10 is installed on one side of the housing 9, and the two housings 9 are rotatably connected via the hinge 10. The fixing plate 8 is fixedly connected to the ends of the two housings 9 away from the hinge 10. The fixing plate 8 has a locking bolt 11 in its middle, which cooperates with the fixing plate 8 to lock the two housings 9. A semi-circular arc-shaped sealing gasket 12 is embedded in the inner wall of the housing 9, and the sealing gasket 12 has an interference fit with the surface of the water supply pipe 1. When the fixing sleeve 3 is installed, the hinge 10 can be used to rotate the housing 9 to wrap around the water supply pipe, and the locking bolt 11 is used to fix the housing 9.

[0029] One end of the housing 9 has a limiting groove 13, which is located at the opposite ends of the two fixed sleeves 3. The limiting grooves 13 on the surfaces of the two housings 9 form a ring. The sealing ring 6 has a cross-shaped cross section, and both ends of the sealing ring 6 are respectively embedded in the limiting grooves 13 on the two fixed sleeves 3. The sealing ring 6 improves the sealing effect of the housing 9 on the water supply pipe when it wraps around the water supply pipe, and increases the friction on the surface of the housing 9 to prevent the water supply pipe from detaching from the pipe body.

[0030] One end of the housing 9 is provided with a connection port 14, and two fixing sleeves 3 are connected through the connection port 14. The end of the housing 9 away from the connection port 14 is provided with an installation port 15, and the installation port 15 is connected to the connection port 14. The water supply pipe body 1 is located in the installation port 15. This allows the water flow from the water supply pipe to enter another water supply pipe through the installation port 15.

[0031] The diameter of the connection port 14 is the same as the inner diameter of the water supply pipe body 1, and the diameter of the mounting port 15 is the same as the outer diameter of the water supply pipe body 1. This reduces the resistance encountered by the water flow when passing through the two fixed sleeves 3.

[0032] Shell 9 is made of high-density polyethylene. It uses the same material as HDPE water supply pipes, which has chemical corrosion resistance, aging resistance and wear resistance.

[0033] The inner wall of the housing 9 is provided with anti-slip patterns. This increases the friction of the inner wall of the housing 9 and improves the fixing effect of the housing 9 on the water supply pipe 1.

[0034] Working principle: When in use, place the connecting end of the water supply pipe body 1 into the housing 9, and make the connecting end of the water supply pipe body 1 contact the side of the mounting port 15 facing the connecting port 14. Then, rotate the housing 9 around the hinge 10 to wrap the fixing sleeve 3 around the surface of the water supply pipe body 1. Install the two fixing sleeves 3 onto the connecting ends of the two water supply pipes respectively. Then, use the connecting bolt 5 to fix the housing 9. Then, put the sealing ring 6 into the slot of one of the fixing sleeves 3. Finally, pass the connecting bolt 5 through the connecting plate 4, and use the connecting bolt 5 to tighten the two fixing sleeves 3 and clamp the sealing ring 6, thereby completing the connection of the water supply pipe.
