AI Technical Summary
Technical Problem
Existing manhole covers are prone to making abnormal noises during use, which affects the environment, causes noise pollution, and distracts drivers, posing a risk of traffic accidents.
Method used
A manhole cover assembly was designed. By setting a support block on the base and inserting a post on the manhole cover, the stability of the connection is enhanced. The friction between the limiting sleeve and the post improves the support effect of the manhole cover and the base, and reduces the risk of abnormal noise.
Benefits of technology
It improves the structural stability of the manhole cover and base, enhances support capacity, reduces abnormal noise and noise pollution, and reduces the risk of traffic accidents.

Abstract
This utility model discloses a manhole cover assembly, comprising: a base, which is a cylindrical structure open at both ends, with at least three mounting parts on the outer surface of the base for installation on a manhole seat; a manhole cover, which closes the opening at the top of the base, with several rainwater holes on the top surface of the manhole cover; wherein, the inner surface of the base is provided with several support blocks arranged at equal angles around its central axis, with insertion holes penetrating through the support blocks, the insertion holes being shaped like inverted frustums, and the top surface of the manhole cover having insertion posts adapted to the insertion holes, with limiting sleeves embedded in the insertion holes. This utility model can improve the stability of the structural connection between the manhole cover and the base, as well as the supporting effect of the base on the manhole cover, reducing the risk of abnormal noise caused by collision between the manhole cover and the base.
