Description

Technical Field

[0001] This utility model relates to a drip irrigation tape connecting buckle and a special tool. Background Technology

[0002] Drip irrigation technology is one of the most widely used water-saving planting techniques, especially in arid regions where its application area is very large.

[0003] In drip irrigation systems, the splicing of drip tape breaks is unavoidable. Currently, snap-on connectors or similar straight-through connectors are commonly used for splicing drip tape breaks.

[0004] The connectors disclosed in CN203215166U, CN202419012U, CN203176590U, and CN202091684U all use socket-type straight pipe fittings and matching locking devices to lock the drip irrigation tape onto the connector in either the forward or reverse direction. Their main drawbacks are complex structure and high cost, which directly increases planting costs. Secondly, they are inefficient to install. In addition, because the connector body is large, it cannot be used before the laying machinery is laid and can only be used after it is laid in the farmland. In actual laying, when encountering a break in the drip irrigation tape, a surplus is left to prevent insufficient length when connecting. However, it is not easy to determine the right surplus length, and too much will result in waste.

[0005] Therefore, a drip irrigation tape connector and special tools that allow for quick connection on seeders or drip irrigation tape laying machines have emerged. Summary of the Invention

[0006] The purpose of this invention is to provide a drip irrigation tape connecting buckle and a special tool that allows for quick connection on seeders or drip irrigation tape laying machines.

[0007] The purpose of this utility model is achieved through the following structure: the drip irrigation tape connecting buckle includes a female buckle (11) and a female buckle (13), characterized in that: the female buckle (11) and the female buckle (13) are a pair of annular cylindrical bodies, the outer diameter of the female buckle (13) is less than or equal to the inner diameter of the female buckle (11), an annular groove (12) or a protrusion (14) is provided on the inner wall of the female buckle (11), and an annular protrusion (14) or a groove (12) is provided on the outer wall of the female buckle (13).

[0008] Furthermore, the aforementioned female buckle (11) and female buckle (13) are preferably cylindrical bodies with an elliptical cross-section.

[0010] Furthermore, in the aforementioned female buckle (11) and female buckle (13), at least one side of the annular groove (12) on the inner wall of the female buckle (11) is an inwardly inclined surface, which makes the cross-section of the groove (12) larger inside and smaller outside in the shape of a swallowtail.

[0011] In the female buckle (11) and the female buckle (13), one side of the protrusion (14) on the female buckle (13) is inclined to the same angle as the inclined surface of the groove (12) on the inner wall of the female buckle (11).

[0012] In the female buckle (11) and the female buckle (13), at least one side of the annular protrusion (14) on the inner wall of the female buckle (11) is an inwardly inclined surface, which makes the cross-section of the protrusion (14) larger inside and smaller outside in the shape of a swallowtail.

[0013] One side of the groove (12) on the female buckle (13) is inclined in a manner corresponding to the inclined surface of the protruding ridge (14) on the inner wall of the female buckle (11).

[0014] Furthermore, preferably, the annular groove (12) or protrusion (14) on the inner wall of the female buckle (11) is symmetrical from the center to both ends, and the annular protrusion (14) or groove (12) on the outer edge of the female buckle (13) is symmetrical from the center to both ends.

[0016] Furthermore, at least one end of the aforementioned pliers (33) is provided with a tapered expansion head (34).

[0017] Furthermore, the opening at the front end of the aforementioned card slot (32) is preferably a wedge-shaped opening that is larger on the outside and smaller on the inside.

[0018] Compared with the prior art, the advantages of this utility model are: it can quickly connect two sections of drip irrigation tape, is easy to install, saves labor, and especially after connection, it can be connected on a seeder or drip irrigation tape laying machine before laying. At the same time, this utility model can also be applied to the connection of other similar flexible pipelines. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Implementation Example 1: Refer to Figure 1-4 This is a schematic diagram of the structure of Embodiment 1 of the present invention, showing a drip irrigation tape connecting buckle, including a female buckle 11 and a female buckle 13. The female buckle 11 and the female buckle 13 are a pair of annular cylindrical bodies. In this embodiment, it is preferred that the female buckle 11 and the female buckle 13 are cylindrical bodies with elliptical cross-sections. The outer diameter of the female buckle 13 is smaller than the inner diameter of the female buckle 11. An annular groove 12 is provided on the inner wall of the female buckle 11 along the circumferential direction, and an annular protrusion 14 is provided on the outer wall of the female buckle 13 along the circumferential direction.

[0034] Furthermore, in this embodiment, in the female buckle 11 and the female buckle 13, one side of the annular groove 12 on the inner wall of the female buckle 11 is an inwardly inclined surface, and the other side of the annular groove 12 on the inner wall of the female buckle 11 is an outwardly inclined surface. The aforementioned inclined surfaces make the cross-section of the groove 12 a groove with a parallelogram shape. The two sides of the protruding ridge 14 on the female buckle 13 are inclined in a manner corresponding to the inclined surface of the groove 12 on the inner wall of the female buckle 11. The inclination angle of the inclined surface of the protruding ridge 14 on the female buckle 13 and the inclined surface of the annular groove 12 on the inner wall of the female buckle 11 can be the same, but preferably they are not the same.

[0035] Furthermore, of the aforementioned female buckle 11 and female buckle 13, at least one end of the female buckle 11 has a funnel-shaped opening that is wider on the outside and narrower on the inside, and one end of the female buckle 13 has a truncated cone-shaped opening that is narrower on the outside and wider on the inside.

[0036] In terms of material selection, the drip irrigation tape connecting buckle of this utility model is preferably made of a material with certain toughness and ductility, such as PVC, PE, engineering plastics, etc., which have certain strength and good deformation performance.

[0037] The present invention is used as follows: The two broken drip irrigation tapes, namely the first drip irrigation tape 21 and the second drip irrigation tape 22, are passed through the middle of the female buckle 11 and the female buckle 13 respectively. The head of the first drip irrigation tape 21 in the female buckle 11 is put on the head of the second drip irrigation tape 22 in the female buckle 13, so that the first drip irrigation tape 21 and the second drip irrigation tape 22 overlap. The female buckle 11 and the female buckle 13 are pressed against each other, so that the female buckle 11 and the female buckle 13 overlap each other, and the first drip irrigation tape 21 and the second drip irrigation tape 22 between the female buckle 11 and the female buckle 13 also overlap each other, thus completing the connection of the two drip irrigation tapes.

[0038] Implementation Example 2: Refer to Appendix Figure 5 The diagram below shows the structure of Embodiment 2 of this utility model. In this embodiment, the two sides of the annular groove 12 on the inner wall of the female buckle 11 are outwardly inclined surfaces. This inclined surface makes the cross-section of the groove 12 trapezoidal with a smaller inner side and a larger outer side. The inner walls on both sides of the groove 12 are funnel-shaped with a smaller inner side and a larger outer side. The two sides of the protruding ridge 14 on the female buckle 13 are inclined in a manner corresponding to the inclined surface of the groove 12 on the inner wall of the female buckle 11. In this embodiment, the inner wall of the female buckle 11 and the outer edge of the female buckle 13 are symmetrical, so the orientation of the female buckle 11 and the female buckle 13 does not need to be considered during use, which is more convenient.

[0039] Implementation Example 3: Refer to Appendix Figure 6The diagram below is a structural schematic of Embodiment 3 of this utility model. In this embodiment, the female buckle 11 and the male buckle 13 are provided with two annular grooves 12 on the inner wall of the female buckle 11 and two annular protrusions 14 on the outer wall of the male buckle 13. In the groove 12, one side is an outward inclined surface and the other side is a right angle surface. The two sides of the protrusions 14 on the male buckle 13 correspond to the inclined surface of the groove 12 on the inner wall of the female buckle 11, with one side being an outward inclined surface and the other side being a right angle surface.

[0040] Implementation Example 4: Refer to Appendix Figure 7 The diagram below is a structural schematic of Embodiment 4 of the present invention. In this embodiment, the female buckle 11 and the female buckle 13 are provided with three annular grooves 12 on the inner wall of the female buckle 11 and three annular protrusions 14 on the outer wall of the female buckle 13. The grooves 12 have a semi-circular cross-section, and the protrusions 14 of the female buckle 13 have a semi-circular cross-section corresponding to the grooves 12.

[0041] Implementation Example 5: Refer to Appendix Figure 8 The diagram below shows the structure of Embodiment 5 of this utility model. In this embodiment, the female buckle 11 and the female buckle 13 have an annular protruding ridge 14 on the inner wall of the female buckle 11 and an annular groove 12 on the outer wall of the female buckle 13. The two sides of the groove 12 are outwardly inclined surfaces, and the two sides of the protruding ridge 14 correspond to the inclined surfaces of the groove 12 on the inner wall of the female buckle 11. The two outwardly inclined surfaces form a chamfer. The left and right chamfers of the inner wall of the female buckle 11 are symmetrical, and the left and right chamfers of the outer edge of the female buckle 13 are also symmetrical. In this embodiment, the orientation of the female buckle 11 and the female buckle 13 does not need to be considered during use, which is more convenient.

[0042] Implementation Example 6: Refer to Appendix Figure 9 The diagram below shows the structure of Embodiment 6 of this utility model. In this embodiment, the female buckle 11 and the female buckle 13 have three annular protruding ridges 14 on their inner wall, and the female buckle 13 has three annular grooves 12 on its outer wall. The cross-sections of the grooves 12 and the protruding ridges 14 are all semi-circular. Embodiment 7: Refer to the attached diagram. Figure 10 The diagram below is a structural schematic of embodiment 7 of this utility model. In this embodiment, the female buckle 11 and the female buckle 13 are provided with an annular protrusion 14 on the inner wall of the female buckle 11. One side of the groove 12 on the outer wall of the female buckle 13 is an outward inclined surface forming a chamfer, and the other side of the groove 12 extends outward to one end of the female buckle 13. The structure of the female buckle is relatively simple, but its orientation needs to be considered in use.

[0043] Implementation Example 8: Refer to Appendix Figure 11-12This is a structural schematic diagram of embodiment 9 of the present utility model. This embodiment is a special tool for connecting drip irrigation tape buckles, including a body composed of a jaw 31 and a handle 33. The feature is that a slot 32 is provided on the jaw 31. The slot 32 is a longitudinal through groove from the head end of the jaw 31 toward the handle 33. The front end of the slot 32 is an open opening.

[0044] Furthermore, both of the aforementioned clamp handles 33 are provided with tapered expansion heads 34 at their ends. These expansion heads can expand the inner diameter of the head of the first drip irrigation tape 21, making it easier to fit onto the second drip irrigation tape 22.

[0045] Furthermore, the opening at the front end of the aforementioned slot 32 is a wedge-shaped opening that is larger on the outside and smaller on the inside, which makes it more convenient to attach the two slots 32 of the special tool for connecting the drip irrigation tape to the first drip irrigation tape 21 and the second drip irrigation tape 22 on the outside of the female buckle 11 and the female buckle 13, respectively.

[0046] Using the special tool for connecting drip irrigation tapes of this utility model is more convenient and faster: the two slots 32 on the jaws 31 of the special tool for connecting drip irrigation tapes are respectively engaged on the first drip irrigation tape 21 and the second drip irrigation tape 22 on the outside of the female buckle 11 and the female buckle 13, and the female buckle 11 and the female buckle 13 are squeezed together until they overlap each other, thus completing the connection.

[0047] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model. Furthermore, this utility model is not limited to its application in the connection of drip irrigation tape, but can also be applied to the connection of other similar flexible pipelines, which should also be considered within the scope of protection of this utility model.
