Technical Field

[0001] The utility model relates to the technical field of drip irrigation, in particular to a PVC drip irrigation pipe which is convenient to install. Background Art

[0002] Drip irrigation is to use a plastic pipe to send water to the root of crops through orifices or drippers on a capillary tube with a diameter of about 10 mm for local irrigation. It is the most effective water-saving irrigation method in arid and water-scarce areas, and the water utilization rate can reach 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation. At the same time, fertilization can be combined to increase the fertilizer efficiency by more than one time. It is applicable to fruit trees, vegetables, cash crops and greenhouse irrigation, and can also be used for field crop irrigation in arid and water-scarce areas.

[0003] The drip irrigation system includes components such as a water pump, a water tank, a drip irrigation water pipe, and a drip irrigation head. By connecting multiple drip irrigation water pipes to each other, a drip irrigation water pipe network is formed on the ground to achieve irrigation of a large-area planting area. When laying the drip irrigation water pipe, it is necessary to ensure the sealing performance of the connection of the drip irrigation water pipe to avoid unnecessary waste caused by water leakage.

[0004] However, in the prior art, when connecting drip irrigation water pipes, clamps or water pipe connectors are required, and tools are needed during assembly, and the operation time is relatively long, resulting in a reduction in the construction efficiency of the drip irrigation water pipe and an increase in the laying time of the drip irrigation water pipe. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that when connecting drip irrigation water pipes, clamps or water pipe connectors are required, and tools are needed during assembly, and the operation time is relatively long, resulting in a reduction in the construction efficiency of the drip irrigation water pipe and an increase in the laying time of the drip irrigation water pipe. For this reason, a PVC drip irrigation pipe which is convenient to install is provided.

[0006] In order to solve the above technical problem, the technical solution of the utility model is as follows:

[0007] A PVC drip irrigation pipe which is convenient to install, including a PVC drip irrigation water pipe, rotary connection rings are rotatably installed at both ends of the PVC drip irrigation water pipe, a plurality of plug-in positioning grooves are opened at both ends of the PVC drip irrigation water pipe, and the plurality of plug-in positioning grooves are distributed in a circular array around the axis of the PVC drip irrigation water pipe. A metal connecting piece is slidably inserted into the inner side of the plug-in positioning groove. The metal connecting piece is made of aluminum alloy and the two ends thereof are bent into a U shape toward one side. The end of the plug-in positioning groove is detachably connected to the rotary connection ring.

[0008] Preferably, the rotary connection ring includes a rotary ring, the outer diameter of the rotary ring is the same as the outer diameter of the PVC drip irrigation water pipe, and a plurality of filling strips distributed in a circular array around its axis are fixed to the inner side of the rotary ring.

[0009] Preferably, an interface is provided between two adjacent filling strips, and a limiting arc rod is fixed at one end of the filling strip, and the limiting arc rod is inserted into the inner side of the end of the metal connector.

[0010] Preferably, the limiting arc rod is arc-shaped and its length is half of the length of the interface, and the length dimension of the limiting arc rod is less than or equal to the width dimension of the metal connector.

[0011] Preferably, the bending radius of the end of the metal connector is the same as the outer diameter of the limiting arc rod, and both sides of the metal connector are arc-shaped and the bending radian is the same as the radian of the limiting arc rod.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. By rotating the rotating ring, the limiting arc rod is misaligned with the insertion positioning groove, and then the end of the metal connector is inserted into the insertion positioning groove. After the metal connector is inserted and the ends of the two PVC drip irrigation water pipes are spliced together, when the rotating ring and the limiting arc rod are rotated, the limiting arc rod is used to catch the end of the metal connector, so that the metal connector connects and fixes the metal connectors at the ends of the two PVC drip irrigation water pipes, thereby realizing the assembly of the two PVC drip irrigation water pipes. Tools are not required during the assembly process, and the operation steps are simple and the operation time is short, improving the assembly and construction efficiency of the drip irrigation water pipes;

[0014] 2. When the drip irrigation water pipe is damaged, only need to rotate the rotating ring, so that the rotating ring drives the limiting arc rod to rotate and the limiting arc rod is misaligned with the insertion positioning groove. At this time, the limiting arc rod is separated from the end of the metal connector layer, and then the two metal connectors are easily disassembled, which is convenient for replacing the damaged PVC drip irrigation water pipe.

[0020] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] As shown in Figure 1 and Figure 2 , rotary connection rings 3 are rotatably installed at both ends of the PVC drip irrigation water pipe 1. A plurality of insertion positioning grooves 4 are opened at both ends of the PVC drip irrigation water pipe 1. The plurality of insertion positioning grooves 4 are distributed in a circular array around the axis of the PVC drip irrigation water pipe 1. A metal connector 2 is slidably inserted inside the insertion positioning groove 4. The metal connector 2 is made of aluminum alloy and the two ends thereof are bent in a U shape to one side. The end of the insertion positioning groove 4 is detachably connected to the rotary connection ring 3. The two rotary connection rings 3 are connected by the metal connector 2 inserted in the insertion positioning groove 4, so as to fix the ends of the two PVC drip irrigation water pipes 1.

[0022] As a preferred technical solution of this embodiment, as shown in Figure 3 and Figure 4 , the rotary connection ring 3 includes a rotary ring 31. The outer diameter of the rotary ring 31 is the same as the outer diameter of the PVC drip irrigation water pipe 1. A plurality of filling strips 32 distributed in a circular array around its axis are fixed inside the rotary ring 31. An interface 34 is provided between two adjacent filling strips 32. One end of the filling strip 32 is fixed with a limiting arc-shaped rod 33. The limiting arc-shaped rod 33 is inserted inside the end of the metal connector 2. The position of the end of the metal connector 2 is restricted by the limiting arc-shaped rod 33, so that the metal connector 2 connects the two rotary connection rings 3.

[0023] The limiting arc-shaped rod 33 is arc-shaped and its length is half of the length of the interface 34. The length dimension of the limiting arc-shaped rod 33 is less than or equal to the width dimension of the metal connector 2. The bending radius of the end of the metal connector 2 is the same as the outer diameter of the limiting arc-shaped rod 33. Both sides of the metal connector 2 are bent in an arc shape and the bending radian is the same as the radian of the limiting arc-shaped rod 33, ensuring that the limiting arc-shaped rod 33 can be smoothly inserted inside the end of the metal connector 2 when rotating with the rotary ring 31 and the filling strip 32, and separating from the end of the metal connector 2 when the limiting arc-shaped rod 33 rotates reversely.

[0024] Working principle: First, rotate the rotating ring 31 at the end of the two PVC drip irrigation water pipes 1. The rotating ring 31 drives the filling strip 32 and the limiting arc-shaped rod 33 to rotate, ensuring that when looking into the insertion positioning groove 4 from the end of the PVC drip irrigation water pipe 1, the limiting arc-shaped rod 33 cannot be seen in the insertion positioning groove 4. At this time, insert one end of the metal connector 2 into the inner side of the insertion positioning groove 4, align and fit the ends of the two insertion positioning grooves 4 with each other. At this time, the insertion positioning grooves 4 at the ends of the two PVC drip irrigation water pipes 1 completely cover the metal connector 2. Then, rotate the rotating ring 31 in the reverse direction. When the rotating ring 31 rotates reversely, it drives the filling strip 32 and the limiting arc-shaped rod 33 to rotate simultaneously. At this time, the limiting arc-shaped rod 33 rotates and resets along with the rotating ring 31. After rotation and reset, the limiting arc-shaped rod 33 is inserted into the inner side of the bent end of the metal connector 2, and the end of the filling strip 32 contacts the side surface of the end of the metal connector 2. At this time, the limiting arc-shaped rod 33 restricts the end of the metal connector 2 and the metal connector 2 cannot be separated from the insertion positioning groove 4. By clamping the end of the metal connector 2 with the limiting arc-shaped rod 33, the metal connector 2 connects and fixes the metal connectors 2 at the ends of the two PVC drip irrigation water pipes 1, thus realizing the assembly of the two PVC drip irrigation water pipes 1. During the assembly process, no tools are required, and the operation steps are simple and the operation time is short, improving the assembly and construction efficiency of the drip irrigation water pipes.

[0025] The above has described the embodiments of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
