[0030] Working principle: Before using the pumping working pipeline connector of this double-well pumping unit, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, by docking the first pipe 1 and the second pipe 101, the baffle 102 and the connecting sleeve 103 are fitted together, so that the insertion rod 201 is inserted into the connecting sleeve 103, the limit box 202, and the fixed frame 209, and the moving plate 204 is driven downward by pressing the moving rod 203. At this time, the moving plate 204 squeezes the first contraction rod 206 and the first telescopic spring 207, and then the moving rod 203 is released, and the tension generated by the first telescopic spring 207 causes the insertion block 205 to engage with the insertion rod 201. The fixing of the limiting rod 201 can achieve the effect of quickly fixing the limiting rod 201, thereby achieving the effect of quickly connecting and fixing the first pipeline 1 and the second pipeline 101. Compared with the bolt fixing method in the prior art, it is more convenient, greatly improving the connection efficiency between the working pipe and the pumping unit, and the connection speed between the working pipes, which brings convenience to the staff when using it. When the rod 201 is inserted into the fixing frame 209, the rod 201 squeezes the fixing seat 210, so that the fixing seat 210 squeezes the second contraction rod 211 and the second telescopic rod 211.

When the insertion rod 201 releases the squeezing of the fixed seat 210, the restoring property of the second telescopic spring 212 is used to push the rotating rod 213 to rotate and the fixed seat 210 to reset, so that the insertion rod 201 can be automatically fixed and engaged. The stability between the baffle 102 and the connecting sleeve 103 is further improved, which brings practicality to the staff when using it. By rotating the rotating plate 216, the torsion spring 217 is stretched, and then by loosening the rotating plate 216, the contraction of the torsion spring 217 can make the rotating plate 216 quickly close with the connecting sleeve 103, thereby preventing external impurities from entering the interior of the connecting sleeve 103. The design of the pull ring 208 makes it easy for the staff to operate the moving rod 203, which brings practicality to the staff when using it.

[0031] By inserting the annular plate 301 into one side of the baffle 102 and then tightening the fixing knob 302, when the baffle 102 and the connecting sleeve 103 are fitted together, the annular plate 301 is inserted into the connecting sleeve 103, thereby squeezing and sealing the first annular sealing gasket 303 and the second annular sealing gasket 304, so that the sealing between the first pipe 1 and the second pipe 101 can be better, and leakage of the connecting part can be prevented. In addition, the design of the detachable annular plate 301 makes it easy for the staff to replace the first annular sealing gasket 303 and the second annular sealing gasket 304, which brings convenience to the staff when using it.
