At this time, when the bayonet 15 is resisted by the inner wall of the feed port 102, the bayonet 15 drives the fixing block 14 to compress the spring 18 through the cooperation of the slider 16 and the slide groove 19. When the bayonet 15 moves to the slot 5, the spring 18 uses its own elastic structure to drive the fixing block 14 and the bayonet 15 to engage with the inside of the slot 5, thereby fixing the mounting cover 2. The first sealing ring 4 and the second sealing ring 21 fit tightly together to greatly enhance the sealing effect of the integrated three-compartment plastic septic tank, thereby improving the sealing of the septic tank body 101 during use. When the installation cover 2 needs to be disassembled, open the cover plate on the top of the installation cover 2, and then rotate the control rod 7, the control rod 7 drives the installation plate 8 to rotate, the installation plate 8 drives the rotating rod 9 to rotate, the rotating rod 9 drives the connecting rod 10 to rotate, and the connecting rod 10 drives the sliding rod 13 to move inside the installation cover 2 through the positioning rod 12. At the same time, the sliding rod 13 drives the pin 15 to disengage from the inside of the slot 5 under the cooperation of the slider 16 and the slide groove 19 through the fixed block 14, so that the pin 15 and the slot 5 are disengaged from the locking structure, and the installation cover 2 can be quickly disassembled and assembled, which greatly improves the convenience during the disassembly and assembly of the installation cover 2, thereby increasing the work efficiency during the disassembly and assembly of the installation cover 2, and thus meets the requirements of high-sealing ecological integrated three-compartment plastic septic tank.
