Description

Technical Field

[0001] The utility model belongs to the technical field of drip irrigation connectors, and more specifically, particularly relates to a novel pipeline connector structure. Background Art

[0002] When performing drip irrigation operations on farmlands, greenhouses, etc., the water pipes often break. When the existing drip irrigation pipes are damaged, generally, the damaged position of the pipe is cut, and then a straight-through joint is used to connect the pipes.

[0003] The existing drip irrigation adapter with the application number: CN200820086900.2 is composed of a drip irrigation adapter main body, a rubber cable ring, and a drip irrigation internal thread. One end of the rubber cable ring is a limiting surface, and the other end is a limiting ring with a limiting surface inside. One end of the drip irrigation adapter main body is provided with elastic claws and a limiting protrusion ring, which can pass through the inner cavity of the rubber cable ring and be limited by the limiting surface of the rubber cable ring. The limiting protrusion ring is limited by the inner limiting surface of the rubber cable ring. The other end is provided with a locking step and a thread, and the thread is connected in cooperation with the internal thread of the drip irrigation internal thread. The advantages of the utility model are as follows: The rubber cable ring and the drip irrigation adapter main body are used to connect with the PVC hard pipe, so the installation is convenient and the sealing performance is high. The drip irrigation internal thread and the drip irrigation adapter main body are used to connect with the drip irrigation belt and are tightened by reverse threads, preventing the drip irrigation internal thread and the drip irrigation belt from falling off. The installation is convenient and fast, the sealing performance is high, and the auxiliary products required in the installation process are omitted.

[0004] Based on the above, when using a straight-through joint to connect drip irrigation pipes, since the existing drip irrigation pipes are mostly made of PVC material, generally a hot melt machine is needed for connection. When using a hot melt machine for connection, the water stored in the pipe needs to be drained before the connection operation can be carried out, resulting in a low installation efficiency of the pipe joint.

The inward movement of the first locking connecting rod drives the second locking connecting rod to rotate. At this time, under the combined action of the second locking connecting rod and the first locking connecting rod, the two groups of connection and locking plates move towards each other to clamp the drip irrigation connecting pipe, facilitating the installation of the entire joint, improving the efficiency of joint docking, avoiding the use of a hot melt machine to connect the pipes, and facilitating the docking of the pipes.
