Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, and specifically relates to a water supply pipeline connector. Background Technology

[0002] Water supply pipeline systems are an indispensable component of modern buildings and urban infrastructure. Their main function is to transport water resources from water sources to various water usage points, including residential buildings, commercial buildings, and industrial facilities. Water supply pipeline systems typically consist of a series of pipes of different diameters to accommodate varying flow and pressure requirements, thereby ensuring a stable supply of water resources.

[0003] In water supply piping systems, connectors play a crucial role. They not only ensure a secure connection between pipes but also guarantee the sealing and stability of the entire system. Connectors allow pipe sections of different lengths and diameters to be interconnected, forming a complete water supply network.

[0004] Although water supply pipe fittings have made some technological progress, existing fittings still have some limitations when connecting water supply pipes of different diameters. On the one hand, fittings with good sealing performance are often non-removable or difficult to disassemble, which can cause difficulties when maintenance or pipe replacement is required. On the other hand, fittings that are easy to disassemble and install often have insufficient sealing performance, which may lead to leaks or other problems, affecting the stability and safety of the system. Utility Model Content

[0005] The purpose of this utility model is to provide a water supply pipe connector to solve the problem mentioned in the background art that existing connectors are difficult to balance the sealing performance and ease of disassembly for water supply pipes of different diameters.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A water supply pipe connector includes: a main water pipe and a branch water pipe, wherein the main water pipe and the branch water pipe are connected by a socket mechanism;

[0008] The socketing mechanism includes a first sleeve and a second sleeve that respectively fit against the inner and outer walls of the branch pipe. The front ends of the first sleeve and the second sleeve are fixedly connected by a connecting ring. The first sleeve is threaded onto the outer wall of the branch pipe. A fixed sleeve is fixedly fitted onto the end of the main pipe near the branch pipe. The front end of the fixed sleeve has a threaded groove. An adapter is threaded into the threaded groove. A slot is opened at the end of the adapter near the branch pipe. The annular inner wall of the slot has an external thread that matches the first sleeve. The first sleeve is threaded into the slot. The second sleeve fits against the inner wall of the adapter. A screw-in assembly is fixedly installed on the outer wall of the first sleeve. The screw-in assembly is connected to the main pipe through a calibration assembly.

[0009] Preferably, the screw-in assembly includes a transmission worm gear fixedly sleeved on the outer wall of the first sleeve, a drive worm gear meshing above the transmission worm gear, and a U-shaped mounting bracket rotatably mounted on both ends of the drive worm gear. A groove is formed on the arc-shaped inner wall of the mounting bracket, and the transmission worm gear is rotatably mounted in the groove.

[0010] Preferably, the calibration assembly includes a telescopic assembly symmetrically arranged along the diameter of the main water pipe and a docking assembly symmetrically arranged along the diameter of the branch water pipe. The telescopic assembly includes a telescopic rod fixedly arranged on the outer wall of the main water pipe, the end of which is connected to the docking assembly. The docking assembly is fixedly arranged on the outer wall of the mounting frame.

[0011] Preferably, the docking assembly includes a positioning plate fixedly mounted on the outer wall of the mounting frame. The positioning plate has a through hole, and the end of the telescopic rod has a threaded hole. The through hole and the threaded hole are opposite each other. A locking bolt is provided on the side of the positioning plate away from the telescopic rod. The locking bolt passes through the through hole and is threaded into the threaded hole.

[0012] Preferably, the branch pipe, the first sleeve, the connecting ring, the adapter, and the fixed sleeve are all fixedly provided with sealing rubber gaskets on their opposite end faces.

[0013] Preferably, one end of the drive worm gear has a hexagonal groove for engaging with an electric drill.

[0014] Preferably, the arc diameter of the mounting bracket is larger than the outer wall diameter of the first sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By using a screw-in assembly to drive the first sleeve, second sleeve, and adapter to perform threaded interlocking, a clever balance between sealing and ease of disassembly is achieved in the water supply pipe connection. This connection method not only ensures a tight fit between the components during installation, minimizing gaps at the connection points and effectively reducing the risk of leakage, but also allows for quick installation and disassembly, greatly facilitating maintenance and repair work. This method ensures efficient and stable connections between water supply pipes of different diameters, while providing a reliable self-locking function to ensure the long-term reliable operation of the water supply system.

[0017] (2) By using the telescopic components symmetrically arranged along the diameter of the main water pipe and the docking components symmetrically arranged along the diameter of the branch water pipe, the coaxiality and alignment of the first sleeve, the second sleeve and the adapter during the installation process are ensured, avoiding poor sealing or unstable connection caused by offset, and also ensuring the stability of the entire socket mechanism during operation.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0025] Example 1:

[0026] Please see Figures 1-4 As shown, a water supply pipe connector includes:

[0027] Main water pipe 1 and branch water pipe 4 are connected by a socket mechanism;

[0028] The socket mechanism includes a first sleeve 5 and a second sleeve 6 that are respectively fitted to the inner and outer walls of the branch pipe 4. The front ends of the first sleeve 5 and the second sleeve 6 are fixedly connected by a connecting ring 7. The first sleeve 5 is threaded onto the outer wall of the branch pipe 4. A fixed sleeve 2 is fixedly fitted onto one end of the main pipe 1 near the branch pipe 4. A threaded groove is opened at the front end of the fixed sleeve 2. An adapter 3 is threaded into the threaded groove. A slot is opened at one end of the adapter 3 near the branch pipe 4. An external thread that matches the first sleeve 5 is provided on the annular inner wall of the slot. The first sleeve 5 is threaded into the slot. The second sleeve 6 is fitted to the inner wall of the adapter 3. A screw-in assembly is fixedly installed on the outer wall of the first sleeve 5. The screw-in assembly is connected to the main pipe 1 through a calibration assembly.

[0029] Depend on Figure 4 It is known that the screw-in assembly includes a transmission worm gear 10 fixedly sleeved on the outer wall of the first sleeve 5. A drive worm 9 is meshed above the transmission worm gear 10. Both ends of the drive worm 9 are rotatably mounted with a U-shaped mounting bracket 8. A groove is opened on the arc-shaped inner wall of the mounting bracket 8. The transmission worm gear 10 is rotatably mounted in the groove. In this way, the mounting bracket 8 will not affect the rotation of the transmission worm gear 10, and the drive worm 9 and the transmission worm gear 10 can always be meshed together, thus ensuring the rotation of the first sleeve 5.

[0030] One end of the drive worm gear 9 has a hexagonal groove for connecting to an electric drill.

[0031] As can be seen from the above, there is usually a certain gap between the main water pipe 1 and the branch water pipe 4. Conventional connectors are designed in a half-and-half form for easy assembly and disassembly, making it convenient to assemble on the water supply pipe. However, this makes it difficult to guarantee the sealing performance. In this utility model, the adapter 3 is first placed between the main water pipe 1 and the branch water pipe 4. Then, the adapter 3 is threaded onto the threaded groove at the front end of the fixed sleeve 2. At this time, the construction worker inserts the drill bit of the electric drill into the hexagonal groove of the drive worm 9, driving the drive worm 9 to rotate, thereby driving the transmission worm wheel 10 and the first sleeve 5 to rotate together. Because the first sleeve 5 is threaded onto the outer wall of the branch water pipe 4, when the first... When the first sleeve 5 rotates, the thread forces the first sleeve 5 to move back and forth, which also drives the drive worm 9 and the mounting bracket 8 to approach the main water pipe 1. Under the action of the calibration component, the first sleeve 5 rotates and approaches the adapter 3 until the first sleeve 5 is threaded into the slot of the adapter 3. The first sleeve 5 and the adapter 3 abut against each other. A part of the adapter 3 is also inserted between the first sleeve 5, the second sleeve 6 and the connecting ring 7. Because the worm gear has self-locking properties and the first sleeve 5 is threaded on the outer wall of the branch water pipe 4, it is ensured that the first sleeve 5 and the second sleeve 6 can be tightly connected to the adapter 3 without external driving force, thus ensuring the sealing of the connection.

[0032] Conversely, when the connection needs maintenance, the worm 9 is driven to rotate in the opposite direction by the electric drill, which drives the transmission worm wheel 10 and the first sleeve 5 to rotate and move away from the main water pipe 1. The adapter 3 will also be driven to rotate out of the fixed sleeve 2 until enough clearance is left. Then the adapter 3 is rotated off the first sleeve 5 to complete the disassembly of the connector.

[0033] Specifically, regarding the above, please refer to... Figure 2 and Figure 3 As shown, the branch pipe 4, the first sleeve 5, the connecting ring 7, the adapter 3, and the fixed sleeve 2 are all fixedly equipped with sealing rubber gaskets on their opposite ends.

[0034] As can be seen from the above, the gasket at the end of the branch pipe 4 ensures the sealing between it and the first sleeve 5 and the second sleeve 7. The gaskets at the ends of the first sleeve 5, the connecting ring 7 and the adapter 3 ensure the sealing when they are plugged into each other. The gasket at the end of the fixed sleeve 2 ensures the sealing between it and the adapter 3.

[0035] Specifically, regarding the above, please refer to... Figure 1 As shown, the arc diameter of the mounting bracket 8 is larger than the outer wall diameter of the first sleeve 5.

[0036] As can be seen from the above, the rotation of the first sleeve 5 will not affect the movement of the mounting bracket 8.

[0037] Example 2:

[0038] refer to Figure 1 As shown, the calibration assembly includes a telescopic assembly symmetrically arranged along the diameter of the main water pipe 1 and a docking assembly symmetrically arranged along the diameter of the branch water pipe 4. The telescopic assembly includes a telescopic rod 11 fixedly arranged on the outer wall of the main water pipe 1, and the end of the telescopic rod 11 is connected to the docking assembly. The docking assembly is fixedly arranged on the outer wall of the mounting frame 8.

[0039] As can be seen from the above, ensuring that the first sleeve 5 can maintain correct alignment during the process of rotating it towards the main water pipe 1, that is, ensuring the coaxiality between the first sleeve 5, the adapter 3, and the branch water pipe 4, can ensure the sealing and stability of the connector after installation, avoid water leakage or other problems caused by eccentricity or misalignment, and also provide necessary mechanical support and guidance for the entire socket mechanism.

[0040] Preferred, Reference Figure 4 As shown, the docking assembly includes a positioning plate 12 fixedly mounted on the outer wall of the mounting bracket 8. The positioning plate 12 has a through hole, and the end of the telescopic rod 11 has a threaded hole. The through hole and the threaded hole are opposite each other. A locking bolt 13 is provided on the side of the positioning plate 12 away from the telescopic rod 11. The locking bolt 13 passes through the through hole and is threaded in the threaded hole.

[0041] As can be seen from the above, the positioning plate 12 and the locking bolt 13 together ensure the stable connection, accurate positioning and effective fixation between the mounting bracket 8 and the telescopic rod 11. At the same time, the locking bolt 13 enables the disassembly between the screw-in assembly and the calibration assembly.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
