Description

Technical Field

[0001] This utility model relates to the field of water conservancy and irrigation technology, specifically to a quick connector for drip irrigation tape used in water conservancy and irrigation. Background Technology

[0002] In the field of water conservancy and irrigation, drip irrigation technology is widely used due to its high efficiency and water-saving characteristics. As a core component, the reliability of the drip irrigation tape's connector directly affects the stability and service life of the irrigation system. Traditional drip irrigation tape connection methods mainly adopt threaded connections or simple plug-in structures.

[0003] For example, CN108571631A discloses a quick connector, relating to the field of automotive manufacturing technology. This invention provides a positioning platform on the female connector body, with a guide protrusion on the outer side of the positioning platform. The guide protrusion protrudes outwards in a manner that first increases and then decreases from the upper support surface to the lower end surface, facilitating the inward shift of the outer edge of the upper support surface and reducing the contact area between the positioning claw and the upper support surface.

[0004] Even when the extension of the male connector's outer leg is small, the positioning claw on the leg can smoothly slide from the upper support surface to the guide protrusion, allowing the worker to smoothly push the connecting lock downwards. The positioning claw of the connecting lock moves smoothly along the guide protrusion to the locking position. However, this quick connector is cumbersome and time-consuming to operate when used for irrigation, and is not suitable for rapid deployment and maintenance of large areas of farmland. Utility Model Content

[0005] The purpose of this utility model is to provide a quick connector for drip irrigation tape used in water conservancy irrigation, so as to solve the problem mentioned in the background art that the quick connector is cumbersome to operate, time-consuming and unsuitable for rapid deployment and maintenance of large areas of farmland.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a quick connector for drip irrigation tape used in water conservancy irrigation, comprising a connector body, one end of which is fixedly connected to a snap-fit ​​mechanism, the snap-fit ​​mechanism comprising a fixing body, the fixing body being movably disposed at one end of the connector body, the inner cavity of the fixing body having a groove, one end of the groove having a fixing post two movably disposed thereon, one end of the fixing post two being fixedly connected to a connecting post two, the outer side of the connecting post two being movably connected to a spring, and one end of the connecting post two and the spring being fixedly connected to a snap-fit ​​post one.

[0008] Furthermore, a connecting post is fixedly connected to the inner cavity of the connector body, a movable post is movably connected to the outer side of the connecting post, and a fixed post is fixedly connected to one end of the connecting post.

[0009] Furthermore, a sealing mechanism is fixedly connected to the outer side of the snap-fit ​​mechanism. The sealing mechanism includes a sealing post one, which is fixedly connected to the outer side of the fixing body. A snap-fit ​​post two is fixedly connected to the outer side of the sealing post one. A snap-fit ​​block one is fixedly connected to the inner cavity of the snap-fit ​​post two. A sealing ring one is fixedly connected to the inner cavity of the sealing post one.

[0010] Furthermore, a second sealing column is movably disposed on one side of the first sealing column, a third snap-fit ​​column is fixedly connected to the outer side of the second sealing column, and a second snap-fit ​​block is fixedly connected to the outer side of the second sealing column. Both the third snap-fit ​​column and the second snap-fit ​​block are fixedly disposed on the outer side of the second sealing column.

[0011] Furthermore, the second snap-fit ​​post and the second snap-fit ​​block are movably connected, and the first snap-fit ​​block and the third snap-fit ​​post are movably connected.

[0012] Furthermore, a second sealing ring is fixedly disposed in the inner cavity of the second sealing column, and the first sealing ring and the second sealing ring are respectively disposed in the inner cavities of the first sealing column and the second sealing column.

[0013] This utility model has the following beneficial effects:

[0014] I. This utility model is equipped with a snap-fit ​​mechanism. The connector body is inserted into the slot of the fixing body, and the snap-fit ​​post one is pushed to compress the spring. After the connector body is in place, the spring rebounds and the drip irrigation tape is fixed by the snap-fit ​​post one. When it is necessary to remove the connector body, press the snap-fit ​​post one to compress the spring and release the connector body to separate it. By setting up a linkage structure of fixing body, slot, fixing post two, connecting post two and spring, the quick assembly and disassembly of drip irrigation tape can be achieved. The operation can be completed without tools, which significantly improves the efficiency of field operation.

[0015] Second, based on the above-mentioned beneficial effects, a sealing mechanism is also provided. The sealing mechanism achieves efficient sealing through nested mechanical locking and the synergistic effect of double sealing rings. Specifically, sealing column one and sealing column two are tightly fastened by the inclined interlocking structure of locking column two, locking block one, locking column three and locking block two to form a seal. At the same time, the embedded sealing ring one and sealing ring two elastically deform after being compressed to fill the gap. The double sealing design not only resists the impact of high-pressure water flow, but also prevents the intrusion of mud and sand. When disassembling, the locking mechanism needs to be unlocked by applying reverse force to ensure stability and leak prevention during field operations. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-2 As shown, this utility model is a quick connector for drip irrigation tape used in water conservancy irrigation, including a connector body 1. One end of the connector body 1 is fixedly connected to a snap-fit ​​mechanism 2. The snap-fit ​​mechanism 2 includes a fixing body 24, which is movably disposed at one end of the connector body 1. The inner cavity of the fixing body 24 is provided with a groove 25. One end of the groove 25 is movably provided with a fixing post 26. One end of the fixing post 26 is fixedly connected to a connecting post 27. A spring 28 is movably connected to the outside of the connecting post 27. One end of the connecting post 27 and the spring 28 is fixedly connected to a snap-fit ​​post 29.

[0025] For example, when connecting a single drip irrigation tape, the locking post 29 needs to provide a locking force of 50-150N (adjusted according to the diameter of the drip irrigation tape). The elastic coefficient of 10-30N / mm can control the compression of the spring 28 to 5-15mm, which is in line with the ergonomic operating range (the finger pressing stroke is usually ≤20mm). The elastic reset function of the spring 28 ensures that the locking post 29 can automatically lock the drip irrigation tape, avoiding accidental detachment due to vibration or water pressure changes. By setting up the linkage structure of the fixing body 24, the slot 25, the fixing post 26, the connecting post 27 and the spring 28, the quick assembly and disassembly of the drip irrigation tape can be achieved without tools.

[0026] The inner cavity of the connector body 1 is fixedly connected to a connecting post 21, the outer side of the connecting post 21 is movably connected to a movable post 22, and one end of the connecting post 21 is fixedly connected to a fixed post 23.

[0027] For example, the movable column 22 can slide along the connecting column 21 to adapt to drip tapes of different diameters, thus increasing compatibility. The fixed column 23 restricts the range of motion to prevent excessive displacement from causing seal failure.

[0028] Working principle: Insert the connector 1 into the slot 25 of the fixing body 24, push the snap-fit ​​post 29 to compress the spring 28. After the connector 1 is in place, the spring 28 rebounds and the drip irrigation tape is fixed by the snap-fit ​​post 29. When it is necessary to remove the connector 1, press the snap-fit ​​post 29 to compress the spring 28 and release the connector 1 to separate it. By setting up the linkage structure of the fixing body 24, the slot 25, the fixing post 26, the connecting post 27 and the spring 28, the quick assembly and disassembly of the drip irrigation tape can be achieved without tools, which significantly improves the efficiency of field operations.

[0029] This step, through the snap-fit ​​mechanism 2, allows users to quickly install the connector body 1 when a quick connection is needed. The operation is simple and improves practicality.

[0030] Please see Figure 3 As shown, this embodiment, based on the above embodiment, further includes a sealing mechanism 3.

[0031] A sealing mechanism 3 is fixedly connected to the outer side of the snap-fit ​​mechanism 2. The sealing mechanism 3 includes a sealing post 31, which is fixedly connected to the outer side of the fixing body 24. A snap-fit ​​post 32 is fixedly connected to the outer side of the sealing post 31. A snap-fit ​​block 33 is fixedly connected to the inner cavity of the snap-fit ​​post 32. A sealing ring 34 is fixedly connected to the inner cavity of the sealing post 31.

[0032] For example, sealing column 1 31 and sealing column 2 35 form a double sealing structure through the nested design of snap-fit ​​column 2 32, snap-fit ​​block 1 33, snap-fit ​​column 36 and snap-fit ​​block 2 37, which effectively prevents high-pressure water leakage.

[0033] A sealing post 35 is movably provided on one side of the sealing post 31. A snap-fit ​​post 36 is fixedly connected to the outside of the sealing post 35. A snap-fit ​​block 37 is fixedly connected to the outside of the sealing post 35. Both the snap-fit ​​post 36 and the snap-fit ​​block 37 are fixedly provided on the outside of the sealing post 35.

[0034] The second snap-fit ​​post 32 and the second snap-fit ​​block 37 are movably connected, and the first snap-fit ​​block 33 and the third snap-fit ​​post 36 are movably connected;

[0035] For example, the second snap-fit ​​block 37 of the sealing post 2 35 engages with the second snap-fit ​​post 32 of the sealing post 1 31, while the first snap-fit ​​block 33 and the third snap-fit ​​post 36 are interlocked.

[0036] A sealing ring 38 is fixedly installed in the inner cavity of the sealing column 35. The sealing ring 34 and the sealing ring 38 are respectively installed in the inner cavities of the sealing column 31 and the sealing column 35.

[0037] For example, sealing ring 34 and sealing ring 38 are made of nitrile rubber (NBR). Nitrile rubber has good oil resistance and a certain resistance to common pesticide and fertilizer solutions; it has high elasticity and can adapt to the compression deformation during joint assembly to a certain extent, achieving a good initial seal; it has a relatively low cost and is suitable for large-scale application in drip irrigation systems with general water quality and operating conditions. Sealing ring 34 and sealing ring 38 are embedded in the inner cavity of the sealing column to further block the leakage path and extend the service life.

[0038] Working principle: The sealing mechanism 3 achieves efficient sealing through nested mechanical locking and the synergistic effect of double sealing rings. Specifically, sealing column 1 31 and sealing column 2 35 are tightly engaged by the inclined interlocking structure of locking column 2 32, locking block 1 33, locking column 3 36 and locking block 2 37 to form a seal. At the same time, the embedded sealing ring 1 34 and sealing ring 2 38 elastically deform after being compressed to fill the gap. The double sealing design resists the impact of high-pressure water flow and prevents the intrusion of mud and sand. When disassembling, the locking mechanism 2 needs to be unlocked by applying reverse force to ensure stability and leak prevention during field operations.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
