Technical Field
[0001] This utility model relates to the field of water supply pipe technology, and in particular to a PE water supply pipe that is easy to disassemble and assemble. Background Technology
[0002] In water supply engineering, PE water supply pipes are widely used due to their advantages such as corrosion resistance and good toughness. However, existing PE water supply pipe connection methods have many problems. For example, heat fusion connection is complex, requires specialized equipment and personnel, and is difficult to disassemble for maintenance and replacement; flange connection structure is relatively complex, costly, and has low installation efficiency. In addition, existing water supply pipes lack real-time monitoring of the connection status, making it impossible to detect abnormalities such as loosening or leakage in a timely manner, which may lead to serious water waste and engineering accidents. Therefore, there is an urgent need for a PE water supply pipe that is both easy to install and disassemble and can monitor the connection status in real time.
[0003] Therefore, it is necessary to develop a PE water supply pipe that is easy to install and disassemble to address the above-mentioned defects. Utility Model Content
[0004] The purpose of this invention is to provide a PE water supply pipe that is easy to install and disassemble. By rotating the locking sleeve and the threaded engagement of the elastic claw, the elastic claw can be driven to radially contract or expand simply by rotating the locking sleeve during installation or disassembly. No complicated tools or operating procedures are required, which greatly saves installation and disassembly time and improves work efficiency.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] This utility model discloses a PE water supply pipe that is easy to assemble and disassemble, comprising a first pipe body, a second pipe body, and a connecting assembly, wherein the connecting assembly includes:
[0007] The elastic clamp assembly is threadedly connected to the second pipe body. The outer side of the elastic clamp assembly is provided with multiple elastic claws distributed circumferentially, and each elastic claw has a threaded section on its outer wall.
[0008] The rotating locking sleeve has an internal thread on its inner wall that matches the threaded section on the outer wall of the elastic claw. When the rotating locking sleeve is rotated, the rotating locking sleeve moves axially, thereby driving the elastic claw to contract or expand radially.
[0009] The first limiting ring is fixed to the front end of the first tube body near the second tube body by a threaded connection;
[0010] The second limiting ring is fixed to the front end of the second pipe body near the first pipe body by a threaded connection, and the adjacent end faces of the first limiting ring and the second limiting ring abut tightly to limit the relative displacement of the first pipe body and the second pipe body in the axial direction.
[0011] A positioning ring is fixedly installed at the end of the first tube body near the second tube body. The end of the second tube body near the first tube body is provided with a groove that matches the shape of the positioning ring. The positioning ring is embedded in the groove to achieve circumferential positioning of the first tube body and the second tube body, and the positioning ring abuts axially with the groove.
[0012] Preferably, the elastic clamp assembly further includes a retaining ring threadedly connected to the second pipe body. The retaining ring is located on the outer side of the second limiting ring away from the first pipe body, and the retaining ring and the second limiting ring are elastically abutted by a fastening washer. The elastic claw is located near the front end of the retaining ring close to the first pipe body, and the second limiting ring is located inside the elastic claw. The front end of the elastic claw is engaged with the outer end face of the first limiting ring away from the second pipe body, thereby limiting and fixing the first pipe body and the second pipe body in the axial direction.
[0013] Preferably, the elastic claw has a locking block at its front end, and the locking block is connected to the locking ring by a connecting rib. The connecting rib can elastically deform when subjected to external force. When the rotating locking sleeve moves axially, the elastic deformation of the connecting rib can assist the elastic claw in radial contraction or expansion. The outer wall of the connecting rib has a threaded section, and the rotating locking sleeve is installed on the outside of the elastic claw through the threaded section. When the rotating locking sleeve rotates, it can move axially along the connecting rib. The upper and lower ends of the locking block protrude from the connecting rib. The lower end of the locking block has a locking structure that matches the shape of the outer end face of the first limiting ring and locks onto the first limiting ring. The upper end of the locking block abuts against the rotating locking sleeve. When the rotating locking sleeve moves axially, it can push the locking block to further lock onto the first limiting ring.
[0014] Preferably, the mating surface of the positioning ring and the groove is tapered, and sealing rings are provided between the mating surfaces and between the abutting bottom surfaces.
[0015] Preferably, the outer surface of the rotating locking sleeve is provided with anti-slip ridges, and the cross-section of the anti-slip ridges is an inverted triangle.
[0016] Preferably, a protective sleeve is provided at the connection between the first tube and the second tube. The protective sleeve is fitted over the outside of the connecting assembly and is made of an elastic material.
[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0018] This utility model presents an easily assembled and disassembled PE water supply pipe. Through the threaded engagement of a rotating locking sleeve and elastic claws, installation and disassembly are achieved simply by rotating the locking sleeve, which drives the elastic claws to radially contract or expand. This eliminates the need for complex tools and procedures, significantly saving installation and disassembly time and improving work efficiency. The front end of the elastic claw is engaged with the outer end face of the first limiting ring, while the adjacent end faces of the first and second limiting rings abut against each other. The positioning ring axially abuts against the groove. This multi-layered limiting and fixing structure ensures the robust connection between the first and second pipe bodies, effectively withstanding internal pressure and external forces, preventing loosening or leakage at the pipe connection. The mating surface between the positioning ring and the groove is tapered and fitted with a sealing ring. The tapered fit ensures a tighter seal, and the sealing ring further enhances the sealing effect, effectively preventing liquid leakage from the water supply pipe, ensuring the normal operation of the water supply system, and avoiding water waste and environmental pollution. The outer surface of the rotating locking sleeve features anti-slip ribs with an inverted triangular cross-section, increasing friction between the operator's hand and the sleeve. This makes it easier to apply force during installation or removal, improving operational convenience and comfort. A newly added protective sleeve, made of elastic material, is fitted over the connecting component. This protects the component from damage caused by external factors such as impact and corrosion, extending its lifespan and enhancing the overall aesthetics of the water pipe connection.

[0024] The core of this utility model is to provide a PE water supply pipe that is easy to install and disassemble. By rotating the locking sleeve and the elastic claw in a threaded engagement, the elastic claw can be driven to radially contract or expand simply by rotating the locking sleeve during installation or disassembly. No complicated tools or operating steps are required, which greatly saves installation and disassembly time and improves work efficiency.
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] Refer to the attached diagram. Figure 1 This is a schematic diagram of the main structure of the PE water supply pipe of this utility model that is easy to assemble and disassemble; Figure 2 This is a top view of the PE water supply pipe of this utility model, which is easy to assemble and disassemble. Figure 3 This is a left-side view of the PE water supply pipe of this utility model, which is easy to assemble and disassemble.
[0028] In one specific implementation, such as Figures 1-3 As shown, a PE water supply pipe that is easy to assemble and disassemble includes a first pipe body 1, a second pipe body 2, and a connecting component, through which the first pipe body 1 and the second pipe body 2 are connected.
[0029] The connecting assembly includes: an elastic clamp assembly 3, which is threadedly connected to the second pipe body 2. The elastic clamp assembly 3 has multiple circumferentially distributed elastic claws 31 on its outer side, and each elastic claw 31 has a threaded section on its outer wall. To ensure installation stability, it is preferable to have 4-6 elastic claws 31.
[0030] The rotating locking sleeve 4 has an internal thread on its inner wall that matches the threaded section on the outer wall of the elastic claw 31. When the rotating locking sleeve 4 is rotated, it moves axially, thereby driving the elastic claw 31 to contract or expand radially. Rotating the rotating locking sleeve 4 causes it to move axially, pushing the elastic claw 31 to contract radially, so that the front end of the elastic claw 31 is engaged with the front end of the elastic claw 31, thus completing the connection between the first tube body 1 and the second tube body 2. During disassembly, rotating the rotating locking sleeve 4 in the opposite direction causes it to move axially in the opposite direction, driving the elastic claw 31 to expand radially, so that the front end of the elastic claw 31 disengages from the first limiting ring 5, thereby separating the first tube body 1 and the second tube body 2.
[0031] The first limiting ring 5 is fixed to the front end of the first tube 1 near the second tube 2 by a threaded connection.
[0032] The second limiting ring 6 is fixed to the front end of the second tube 2 near the first tube 1 by a threaded connection, and the adjacent end faces of the first limiting ring 5 and the second limiting ring 6 are tightly abutted to limit the relative displacement of the first tube 1 and the second tube 2 in the axial direction.
[0033] The positioning ring 101 is fixedly installed at the end of the first tube 1 near the second tube 2. The end of the second tube 2 near the first tube 1 is provided with a groove 201 that matches the shape of the positioning ring 101. The positioning ring 101 is embedded in the groove 201 to achieve circumferential positioning of the first tube 1 and the second tube 2, and the positioning ring 101 abuts against the groove 201 axially.
[0034] The engagement of the elastic claw 31 and the rotating locking sleeve 4 enables rapid assembly and disassembly of the pipe body without the need for complex tools and operating procedures, saving installation and disassembly time and improving work efficiency. The mating structure of the first limiting ring 5, the second limiting ring 6, the positioning ring 101, and the groove 201 limits and fixes the pipe body axially and circumferentially, ensuring the firmness of the connection, and enabling it to withstand internal pipe pressure and external forces, preventing loosening or leakage.
[0035] In one specific implementation, such as Figures 1-3 As shown, the elastic clamp assembly 3 also includes a retaining ring 32 threadedly connected to the second pipe body 2. The retaining ring 32 is located on the outer side of the second limiting ring 6 away from the first pipe body 1, and the retaining ring 32 and the second limiting ring 6 are elastically abutted by a fastening washer. The fastening washer serves as a buffer and seal. The elastic claw 31 is located near the front end of the retaining ring 32 close to the first pipe body 1, and the second limiting ring 6 is located inside the elastic claw 31. The front end of the elastic claw 31 is engaged with the outer end face of the first limiting ring 5 away from the second pipe body 2, thereby limiting and fixing the first pipe body 1 and the second pipe body 2 axially.
[0036] In one specific implementation, such as Figures 1-3As shown, the elastic claw 31 has a locking block 311 at its front end. The locking block 311 is connected to the locking ring 32 by a connecting rib 312, which can elastically deform under external force. When the rotating locking sleeve 4 moves axially, the elastic deformation of the connecting rib 312 can assist the radial contraction or expansion of the elastic claw 31. The outer wall of the connecting rib 312 has a threaded section, and the rotating locking sleeve 4 is installed on the outside of the elastic claw 31 through the threaded section. When the rotating locking sleeve 4 rotates, it can move axially along the connecting rib 312. The upper and lower ends of the locking block 311 protrude from the connecting rib 312. The lower end of the locking block 311 has a locking structure that matches the shape of the outer end face of the first limiting ring 5 and is locked onto the outer side of the first limiting ring 5. The upper end of the locking block 311 abuts against the rotating locking sleeve 4. When the rotating locking sleeve 4 moves axially, it can push the locking block 311 to further lock onto the first limiting ring 5. The elastic deformation of the connecting rib 312 makes the radial contraction or expansion of the elastic claw 31 smoother, improving the convenience of assembly and disassembly. The snap-fit structure between the locking block 311 and the first limiting ring 5, as well as the pushing action of the rotating locking sleeve 4 on the locking block 311, further enhances the stability and reliability of the connection, preventing loosening at the connection point. During the locking process between the rotating locking sleeve 4 and the elastic claw 31, the rotating locking sleeve 4 and the elastic claw 31 are threadedly connected. Even if loosening occurs between the rotating locking sleeve 4 and the elastic claw 31 during the locking process, the locking block will not disengage from the end face of the first limiting ring 5, and the first tube body 1 and the second tube body 2 will not be affected by the loosening of the rotating locking sleeve 4.
[0037] In one specific implementation, such as Figures 1-3 As shown, the mating surfaces of the positioning ring 101 and the groove 201 are tapered, utilizing the self-locking property of the taper to ensure a tighter fit. Furthermore, sealing rings are provided between the mating surfaces and between the mating bottom surfaces. The elastic deformation of these sealing rings fills the gaps, achieving a seal. This effectively prevents liquid leakage from the water supply pipe, ensuring the normal operation of the water supply system and avoiding water waste and environmental pollution.
[0038] In one specific implementation, such as Figures 1-3 As shown, the outer surface of the rotating locking sleeve 4 is provided with anti-slip ribs, the cross-section of which is an inverted triangle. When the operator's hand comes into contact with the rotating locking sleeve 4, the inverted triangular anti-slip ribs increase the friction between the hand and the rotating locking sleeve 4, preventing hand slippage and facilitating the application of force.
[0039] In one specific implementation, such as Figures 1-3As shown, a protective sleeve 7 is also provided at the connection between the first pipe body 1 and the second pipe body 2. The protective sleeve 7 is fitted onto the outside of the connecting component and is made of an elastic material. The elastic material is made of rubber, which has increased elasticity. Fitted onto the outside of the connecting component, it protects the connecting component and prevents the rotation locking sleeve 4 from loosening. It also prevents damage to the connecting component from external environmental factors such as collisions and corrosion, thus extending the service life of the connecting component.
[0040] The operation process of this utility model's easy-to-assemble and disassemble PE water supply pipe is as follows: The elastic clamp assembly 3 is threaded onto the front end of the second pipe body 2, and then fixed onto the second pipe body 2 by the second limiting ring 6. The elastic claw 31 is in a naturally expanded state initially. The first limiting ring 5 is threaded onto the front end of the first pipe body 1. The first pipe body 1 and the second pipe body 2 are brought close together, aligning the positioning ring 101 of the first pipe body 1 with the groove 201 of the second pipe body 2. The positioning ring 101 is slowly inserted into the groove 201 until the adjacent end faces of the first limiting ring 5 and the second limiting ring 6 are tightly abutted. As the first pipe body 1 and the second pipe body 2 approach each other, the elastic claw 31 at the front end of the elastic clamp assembly 3 opens outward under the action of the first limiting ring 5 until the inner side of the locking block 311 at the front end of the elastic claw 31 abuts against the outer side of the first limiting ring 5. Holding the rotating locking sleeve 4, rotate it clockwise. The rotating locking sleeve 4 moves axially along the threaded section of the outer wall of the elastic claw 31, gradually pushing the elastic claw 31 to retract radially. Until the front end of the rotating locking sleeve 4 abuts against the side of the locking block 311, as the elastic claw 31 retracts, the locking block 311 at the front end of the elastic claw 31 is locked onto the outer end face of the first limiting ring 5. During disassembly, holding the rotating locking sleeve 4, rotate it counterclockwise. The rotating locking sleeve 4 moves axially in the opposite direction along the threaded section of the outer wall of the elastic claw 31. As the rotating locking sleeve 4 moves, the elastic claw 31 gradually expands radially under its own elasticity and the action of the connecting rib 312, and the locking block 311 at the front end of the elastic claw 31 separates from the outer end face of the first limiting ring 5. When the elastic claw 31 is fully expanded, it separates the first tube 1 and the second tube 2, completing the disassembly operation.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
[0042] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
