[0026] The inner wall of the first interface is connected to a retaining ring, which is in a locked state in its natural state and is used to lock the irrigation water pipe inserted into the first interface.

[0027] The outer wall of the first interface is provided with a limiting protrusion;

[0028] The second interface is used to connect external pipes to an external irrigation device;

[0029] The screwing component includes a bottom wall, an inner annular wall forming a third inner cavity, and an outer annular wall, with an annular groove formed between the inner and outer annular walls; an arc-shaped groove that mates with the limiting protrusion is provided on the outer annular wall; the arc-shaped groove is inclined along the height direction of the outer annular wall to form a lower first position and a higher second position; the third inner cavity is used to insert the irrigation water pipe;

[0030] The limiting protrusion moves back and forth between the first position and the second position to switch the release or locking state of the retaining ring, thereby unlocking or locking the irrigation water pipe.

[0031] A further preferred embodiment of this utility model is: the outer wall of the second interface is provided with external threads for screwing into the outer pipe section of the irrigation device;

[0032] The inner side of the retaining ring is provided with a water-sealing component. When the irrigation water pipe is inserted into the first interface, the water-sealing component is tightly fitted to the outer wall of the irrigation water pipe to achieve a sealed connection.

[0033] A further preferred embodiment of this utility model is: the bottom wall is provided with a radially outwardly extending protrusion to serve as a rotating handle;

[0034] Rotate the rotating handle in the forward direction to move the limiting protrusion from the first position of the arc-shaped groove to the second position. The inner annular wall presses against the retaining ring, causing the retaining ring to deform from the locked state to the released state. At this time, the irrigation water pipe can be inserted into the first interface.

[0035] Rotate the rotating handle in the opposite direction to move the limiting protrusion from the second position of the arc groove to the first position. The inner annular wall retracts, causing the retaining ring to return from the released state to the locked state, thereby securely connecting the irrigation water pipe into the first interface.

[0036] Compared with existing technologies, the advantages of this invention are: traditional irrigation water pipe connectors present an irreconcilable contradiction between connection strength and ease of operation, while this technical solution cleverly balances these two aspects through a specific locking and releasing mechanism. Users can easily and quickly connect and disconnect irrigation water pipes simply by rotating the screw in both directions, without the need for complex tools or cumbersome procedures. This technology not only significantly reduces operational difficulty but also substantially improves the maintenance efficiency of the irrigation system, making irrigation operations more efficient and convenient.

[0037] Specifically, on the one hand, the locking and releasing mechanism of the retaining ring ensures the firmness and sealing of the irrigation water pipe during connection, effectively preventing water waste and poor irrigation effect caused by loose connection or leakage; on the other hand, through the cooperation of the arc groove and the limiting protrusion, users only need to rotate the screw in the forward and reverse directions to easily complete the connection and disassembly of the water pipe, which significantly reduces the difficulty of operation and time cost.

[0038] In summary, this utility model's irrigation water pipe connector not only optimizes the balance between connection strength and operational difficulty but also significantly improves connection repeatability. Users experience clear operational feedback when installing and disassembling irrigation water pipes, reducing operational difficulty and time costs. Simultaneously, the locking and releasing mechanism of the retaining ring ensures the connection's strength and sealing, effectively preventing irrigation water leakage and improving water resource utilization efficiency. This, in turn, enhances the overall performance of the irrigation system. Attached Figure Description

[0049] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0050] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0051] The irrigation system includes an irrigation water pipe p, an irrigation water pipe connector 100, and an irrigation device. The irrigation water pipe connector 100 enables an efficient and reliable connection between the irrigation water pipe p and the irrigation device.

[0052] The irrigation water pipe connector 100 consists of a main connector 10 and a screwing component 20. The main connector 10 includes a first interface 11, a transition section 13, and a second interface 12. The first inner cavity h1 of the first interface 11 is connected to the second inner cavity h2 of the second interface 12 through the flow channel of the transition section 13, ensuring that water can flow smoothly.

[0053] The inner wall of the first interface 11 is connected to a retaining ring 14, which is in a locked state in its natural state. This retaining ring securely holds the irrigation water pipe p inserted into the first interface 11, effectively preventing the water pipe from loosening or falling off during use, thereby ensuring the stable operation of the irrigation system. The outer wall of the first interface 11 is provided with a limiting protrusion 15, which cooperates with the arc-shaped groove 24 of the screwing component 20 to switch between the release and locking states of the retaining ring 14.

[0054] The screwing component 20 includes a bottom wall 21, an inner annular wall 22 forming a third inner cavity h3, and an outer annular wall 23. An annular groove f is formed between the inner annular wall 22 and the outer annular wall 23 to accommodate the first interface 11 of the main connector 10. The arc-shaped grooves 24 on the outer annular wall 23 are distributed obliquely along the height direction, forming a lower first position s1 and a higher second position s2. The first position s1 is the initial state, at which time the retaining ring 14 is in a locked state to ensure that the irrigation water pipe p will not be accidentally loosened when not in operation; while the second position s2 is the released state, allowing the irrigation water pipe p to be inserted or removed.

[0055] By rotating the screwdriver 20 in either the forward or reverse direction, the limiting protrusion 15 moves back and forth between the first position s1 and the second position s2 of the arc-shaped groove 24, thereby releasing or locking the retaining ring 14, and thus completing the unlocking or locking operation of the irrigation water pipe p. This technique is not only simple to operate but also reliable in connection, greatly improving the practicality and convenience of the irrigation system.

[0056] Furthermore, the second interface 12 of the main connector 10 is used to connect to an external pipe on the irrigation device. Its outer wall is provided with an external thread k. This thread allows the second interface 12 to be tightly connected to the external pipe section of the irrigation device, ensuring the connection's firmness and sealing of the entire irrigation system. This threaded connection not only provides extremely high connection firmness, ensuring that it will not loosen or fall off even under high water pressure during irrigation, but also effectively prevents leakage through the sealing performance of the thread, greatly improving the overall sealing of the irrigation system. Moreover, the threaded connection simplifies the installation process and enhances the system's reliability and stability.

[0057] Preferably, to further improve the sealing performance and ease of installation of the irrigation water pipe joint 100, a water-sealing element 30 is provided on the inner side of the retaining ring 14. The outer side of the water-sealing element 30 has a bevel 31, which not only guides the irrigation water pipe p to be smoothly inserted into the first interface 11, but also automatically adjusts the fit between the water-sealing element and the outer wall of the water pipe during the insertion process.

[0058] When the irrigation water pipe p is fully inserted into the first interface 11, the inclined surface 31 of the water sealing component 30 will fit tightly against the outer wall of the water pipe, forming a reliable sealing barrier, effectively preventing leakage of irrigation water during transmission, and ensuring that the water flow can be efficiently and without damage to the irrigation area.

[0059] In the actual operation of the irrigation system, the irrigation water pipe p and the main connector 10 can be quickly connected and disconnected by rotating the handle 211 in both directions. The specific operation steps are as follows:

[0060] When the irrigation water pipe p needs to be connected to the main connector 10, the operator rotates the rotary handle 211 clockwise. At this time, the limiting protrusion 15 smoothly moves along the arc groove 24 from the lower first position s1 to the higher second position s2. As the limiting protrusion 15 moves, the inner annular wall 22 of the screwing part 20 gradually presses the retaining ring 14 inward. Under the action of the inner annular wall 22, the retaining ring 14 deforms from the initial locked state and changes to the released state, as shown. Figure 5 As shown. At this point, the constraint force of the retaining ring 14 on the irrigation water pipe p disappears, providing sufficient space for the irrigation water pipe p to be smoothly inserted into the first interface 11. The operator can easily insert the irrigation water pipe p into the first interface 11 to complete the initial connection operation.

[0061] After the irrigation water pipe p is inserted into place, the operator rotates the handle 211 in the opposite direction. At this time, the limiting protrusion 15 moves smoothly back from the second position s2 to the first position s1 along the arc groove 24. As the limiting protrusion 15 moves, the inner annular wall 22 of the screwing part 20 gradually retracts. The retraction of the inner annular wall 22 causes the retaining ring 14 to lose the constraint of external force, thus returning from the released state to the locked state. In the locked state, as... Figure 4 As shown, the retaining ring 14 tightly engages with the outer wall of the irrigation water pipe p, generating strong friction and clamping force to firmly fix the irrigation water pipe p within the first interface 11. This robust connection not only withstands the water pressure generated during irrigation but also effectively prevents the irrigation water pipe p from loosening or falling off due to external forces, ensuring the stable operation of the irrigation system. Through the cooperation of the screw-on part 20 and the retaining ring 14, the irrigation water pipe connector 100 achieves quick, convenient, and reliable connection and disassembly functions. The operation of rotating the handle 211 in both directions is simple and easy, requiring no complex tools or cumbersome steps, greatly improving the installation and maintenance efficiency of the irrigation system.

[0062] Meanwhile, the switching between the locking and releasing states of the retaining ring 14 ensures the sealing and firmness of the irrigation water pipe p during the connection process, effectively preventing leakage of irrigation water, improving the utilization efficiency of water resources, reducing irrigation costs, and thus enhancing the overall performance of the irrigation system.

[0063] Preferably, such as Figure 8 and Figure 9 As shown, where Figure 8 This is a schematic diagram showing the card ring 14 in the released state. Figure 9This diagram illustrates the initial locked state of the retaining ring 14 teeth v. It should be noted that, in this technical solution, the definitions of the locked and released states of the retaining ring 14 are based on its actual effect on the irrigation water pipe p. Specifically, the locked state refers to the retaining ring 14 applying sufficient constraint force to the water pipe p to ensure its secure and stable operation during irrigation; while the released state refers to the release of the constraint force of the retaining ring 14 on the water pipe p, facilitating the insertion or removal of the water pipe p.

[0064] The retaining ring 14 includes an annular connecting portion 141 and an annular toothed portion 142. The annular toothed portion 142 is connected to the inner side of the annular connecting portion 141, and the outer side of the annular connecting portion 141 is welded to the inner wall of the first interface 11. The annular connecting portion 141 is fixed to the inner wall of the first interface 11 by welding. This firm connection method ensures that the retaining ring 14 will not loosen or shift due to external force or water pressure during use.

[0065] The annular toothed part 142 is located inside the retaining ring 14 and directly contacts the outer wall of the irrigation water pipe p. The toothed design increases the friction with the outer wall of the water pipe, allowing the retaining ring 14 to more firmly engage with the water pipe in the locked state, preventing the water pipe from loosening or falling off due to water pressure or external force during irrigation.

[0066] The annular toothed portion 142 includes multiple teeth v, with gaps between the teeth v. The gaps between the teeth v give the annular toothed portion 142 a certain elastic deformation capacity, enabling it to better adapt to irrigation water pipes p with different outer diameters. Even if the outer diameter of the water pipe has certain tolerances or irregular shapes, the toothed portion can still fit tightly against the outer wall of the water pipe through its own elastic adjustment, thereby achieving a reliable sealing connection.

[0067] like Figure 9 As shown, the locking state of the retaining ring 14 is that the annular teeth 142 are in a horizontally extended state, with the teeth v gripping the surface of the irrigation water pipe p, as shown. Figure 5 As shown; Figure 8 As shown, the released state of the retaining ring 14 is that the annular tooth 142 is in a downward retracted state, and the tooth v relaxes the surface of the irrigation water pipe p, as shown. Figure 4 As shown.

[0068] Furthermore, it should be noted that the teeth (V) have multiple contact points with the outer wall of the water pipe, and each tooth (V) can apply a certain amount of pressure to the water pipe when locked. This multi-point contact method greatly increases the sealing area, effectively preventing leakage of irrigation water during transmission.

[0069] Furthermore, it should be noted that due to the gap between the teeth V, the retaining ring 14 can release the constraint force on the water pipe p more promptly and quickly when switching from the locked state to the released state. This allows the irrigation water pipe p to be inserted or pulled out more easily, improving the efficiency of water pipe installation and disassembly.

[0070] Preferably, the outer surface of the inner annular wall 22 has a bevel 221 to form a taper. The bevel 221 allows the inner annular wall 22 to guide the deformation of the retaining ring 14 more smoothly when pressing against it, reducing the resistance of the retaining ring 14 during the deformation process; moreover, the bevel 221 allows the inner annular wall 22 to distribute pressure more evenly when in contact with the retaining ring 14, reducing localized excessive wear.

[0071] When the screwing component 20 rotates forward, and the limiting protrusion 15 moves from the first position s1 to the second position s2 of the arc-shaped groove 24, the inclined surface 221 of the inner annular wall 22 gradually presses the retaining ring 14 inward. Due to the presence of the inclined surface 221, the inner annular wall 22 can apply pressure more evenly, causing the annular teeth 142 of the retaining ring 14 to deform from the locked state to the released state. This even force distribution not only ensures that the retaining ring 14 can firmly engage with the outer wall of the irrigation water pipe p in the locked state, but also reduces local stress concentration and extends the service life of the retaining ring 14.

[0072] When the screwing component 20 rotates in the opposite direction, and the limiting protrusion 15 moves from the second position s2 to the first position s1 of the arc-shaped groove 24, the inclined surface 221 of the inner annular wall 22 gradually retracts, and the retaining ring 14 returns from the released state to the locked state. The design of the inclined surface 221 allows the retaining ring 14 to quickly and smoothly return to the locked state.

[0073] In summary, the tapered structure of the inclined surface 221 makes the fit between the inner annular wall 22 and the retaining ring 14 tighter and more efficient, thus optimizing the locking and releasing performance of the retaining ring 11.

[0074] Preferably, the bottom wall 21 has a radially outwardly extending protrusion 211 as a rotating handle. The radial extension of the rotating handle allows the user to easily grasp the handle with their fingers or hand, providing a good grip; moreover, the radially extended outer end of the handle provides the user with a clear operating direction, reducing the possibility of misoperation.

[0075] In addition, the shape and position design of the rotating handle is intuitive and clear. Users can switch the position of the limiting protrusion 15 in the arc groove 24 by rotating the handle 211 without additional tools or complicated operating steps, thereby completing the connection and disconnection of the irrigation water pipe p.

[0076] Preferably, the first position s1 of the arc groove 24 is provided with a first positioning groove 01, and the second position s2 of the arc groove 24 is provided with a second positioning groove; the lower side of the limiting protrusion 15 is provided with a positioning protrusion 151.

[0077] The first positioning groove 01 and the second positioning groove correspond to the first position s1 and the second position s2 of the arc groove 24, respectively. When the limiting protrusion 15 moves to these two positions, the positioning protrusion 151 on its lower side can be accurately embedded in the corresponding positioning groove, thereby ensuring that the limiting protrusion 15 is accurately locked in the two key positions, so that the screwing part 20 can remain stable in both the locked and released states and will not move accidentally due to external force or vibration.

[0078] Preferably, two rotating handles 211 are symmetrically arranged on both sides of the bottom wall 21. This symmetrical arrangement allows the user to easily find the handles and operate the component from any direction when approaching it.

[0079] The protrusion transitions seamlessly into the bottom wall 21, and a stress-bearing arc wall is formed on one side of the protrusion and the bottom wall 21, providing a good point of leverage for manual twisting. During the twisting process, the user's fingers can naturally rest on the stress-bearing arc wall to twist.
