[0040] The working principle of this utility model:

[0041] When pipe 2 needs to be installed, place pipe 2 in a suitable position, align the connection hole of flange 5 with the positioning pin 4 on the front side of connecting plate 3, and then push pipe 2 backward so that positioning pin 4 enters the inner cavity of connection hole of flange 5. Then rotate one side control component 806 to drive pulley 804 and double-ended screw 801 to rotate synchronously. One side pulley 804 will drive the other side pulley 804 and double-ended screw 801 to rotate synchronously through toothed belt 805. During the rotation of double-ended screw 801, it will drive the first connecting sleeve 802 and the second connecting sleeve 803 to move closer to each other. When the first connecting sleeve 802 and the second connecting sleeve 803 move... When the device reaches the appropriate position, the inner walls of the first connecting sleeve 802 and the second connecting sleeve 803 will contact the connecting plate 3 and the flange 5. At the same time, the opposite sides of the first connecting sleeve 802 and the second connecting sleeve 803 will contact each other, stopping the rotation of the control component 806. The first connecting sleeve 802 and the second connecting sleeve 803 will no longer move. Then, the control switch 905 will be turned to drive the control screw 903 to rotate synchronously. The control screw 903 will drive the limit plate 904 and the limit post 906 to move synchronously. The limit post 906 will drive the locking block 902 to move, so that the locking block 902 contacts the tooth groove of the control component 806, fixing the control component 806 and completing the installation.

[0042] In summary, this leak-proof liquid source delivery device, through the coordinated use of connecting plate 3, positioning column 4, flange 5, fixing ring 6, support frame 7, fixing device 8, and control device 9, solves the problem that existing magnetic pumps and pipelines typically require aligning the pipeline flange with the flange at the front connection port of the magnetic pump body, and then tightening bolts to fix the pipeline, making the installation and disassembly process inconvenient.
