[0029] The working principle of the above embodiment is:

[0030] The disassembly and assembly structure of the cast iron manhole cover is as follows: when in use, first put your hand into the through groove 501, lift the whole device through the through groove 501, hook the pull ring 12 with your fingers to stretch it, pull the pull ring 12 to drive the connecting plate 11 to move, the connecting plate 11 drives the slider 8 and the limit block 10 to move, the slider 8 moves on the fixed shaft 6 and compresses the telescopic spring 7, thereby driving the limit rod 13 to shrink, and then put the manhole cover bottom plate 2 into the sewer wellhead on the inner side of the concrete body 1, and align the limit rod 13 with the slot on the inner side of the concrete body 1, and then release the pull ring 12, the telescopic spring 7 starts to reset automatically, and the reset of the telescopic spring 7 drives the slider 8 to reset and move on the fixed shaft 6, and the movement of the slider 8 drives the connecting plate 11 in turn The limit block 10 and the slider 8 can move the connecting plate 11 to move smoothly in a straight line, so that the connecting plate 11 drives the limit rod 13 to be accurately inserted into the slot of the concrete main body 1, thereby fixing the bottom plate 2, the support plate 4 and the top plate 5 of the manhole cover to the surface of the concrete main body 1. Similarly, the pull ring 12 is pulled to drive the connecting plate 11 and the limit rod 13 to shrink, so that the limit rod 13 is separated from the limit fixation of the concrete main body 1, and then the entire device is removed from the surface of the concrete main body 1 through the through groove 501, which is conducive to quick installation and disassembly. When it rains during use, rainwater flows downward and can intercept tree leaves and impurities when passing through the interception net 3, which is conducive to improving the practicality of the device.
