[0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet to the ground at every section. The section from the pipeline to the ground is called a manhole, but the existing manhole cover structure still has certain defects when in use.

[0003] The defects of the manhole cover structure in the prior art are:

[0004] At present, patent document CN219240629U discloses a manhole cover structure, including a manhole cover and a manhole seat, wherein a mounting cavity for placing the manhole cover is provided in the manhole seat, and a plurality of support blocks evenly arranged along the circumference of the manhole seat are fixedly connected in the mounting cavity, and an arc-shaped groove is provided on the side of the support block along the axial direction of the manhole seat, and a mounting hole is provided in the middle of the upper end surface of the manhole cover, and a locking mechanism is provided at the mounting hole, and the locking mechanism includes a round rod extending through the through hole into the mounting cavity, and an arc-shaped positioning rod that can be inserted into the arc-shaped groove is provided outside the round rod. The utility model fixes the arc-shaped positioning rod on the round rod, and then inserts the arc-shaped positioning rod into the arc-shaped groove by rotating the locking mechanism in the mounting hole, thereby locking the manhole cover and the manhole seat, thereby preventing the manhole cover from detaching from the manhole cover after being subjected to external force. Through the structure in this embodiment, the locking mechanism is located in the mounting cavity and the mounting hole, which can avoid affecting the passage of pedestrians and vehicles.

When the locking mechanism is used to lock and open the manhole cover body 13, the rotating bolt 14 is rotated by an external tool. When the rotating bolt 14 rotates, the engaging plate 16 can be driven to rotate by the transmission rod 15. When the engaging plate 16 rotates and is in a vertical state with the limiting groove 8, the manhole cover body 13 can be locked.
