[0021] See also Figures 1 to 4The utility model provides a technical solution: an anti-sinking manhole cover, including an annular seat 5, a connecting pipe 15 is coaxially fixedly connected inside the annular seat 5, the top of the annular seat 5 is coaxially connected to the support 4 and the limit seat 6 in sequence from the inside to the outside, the outer wall of the connecting pipe 15 is coaxially connected to a plurality of inclined plates 16 with their ends extending downward from top to bottom, the outer edge of the bottom of the annular seat 5 is coaxially connected to the reinforcement seat 7, and the inner wall of the reinforcement seat 7 is an outward extending inclined surface, such as Figure 2 、 3 , 5, when actually installed and used, the annular seat 5 is placed on the reserved base ( Figure 5 At this time, the bottom of the connecting pipe 15 is connected to the municipal drainage pipe ( Figure 5 The reinforcing seat 7 and the inclined plate 16 are coaxially connected and fixed with cement on the base. The cement fills the bottom of the reinforcing seat 7 and the inclined plate 16 and is flush with the top of the limiting seat 6. The stable installation of the annular seat 5 and the connecting pipe 15 can be achieved. The reinforcing seat 7 and the inclined plate 16 increase the contact area between the bottom of the annular seat 5 and the outer wall of the connecting pipe 15 and the cement, thereby improving the stability of the overall installation and effectively avoiding settlement.

[0022] like Figure 2 、 3 As shown in Figure 4, the height of the support 4 is lower than the height of the limiting seat 6, and a top cover 3 is coaxially arranged on the top of the support 4. A leakage hole 2 for drainage and an anti-slip protrusion 19 for improving the anti-slip performance of the top are provided on the top of the top cover 3. At the same time, a plurality of first openings 10 are circumferentially opened on the top of the support 4, and a second opening 14 is extended from the bottom of the first opening 10. An L-shaped structure is formed between the second opening 14 and the first opening 10. The side wall of the fixing seat 9 is fixedly connected to a limiting plate 8 matched with the first opening 10. When the top cover 3 is installed, it is placed on the top of the support 4. At this time, the limiting plate 8 is located in the first opening 10, and the top cover 3 is rotated to drive the limiting plate 8 to move into the second opening 14, further improving the stability of the top cover 3 installed on the top of the support 4, and avoiding settlement caused by shaking of the top cover 3 during long-term use.
