Detailed Description

The following further describes the embodiments of the present invention. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

In the description of the present invention, the terms "right", "front", "rear" and "inner" indicate the position or positional relationship based on the position or positional relationship shown in the drawings, which is only for convenience of description of the present invention and does not require the present invention to be constructed and operated in a specific position, and thus, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "rotated," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; they may be mechanically coupled, directly coupled, or indirectly coupled through intervening media, such that there is communication between the two elements or there is an interaction between the two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1 to 8, it is a square manhole cover for preventing theft and falling, comprising a manhole cover 1, a manhole cover frame 2 and a bottom frame 3; well lid frame 2 covers on underframe 3 and fixes a position, but 1 pivoted of well lid covers on well lid frame 2 and the bearing is on underframe 3, and the inner wall leanin of 2 right-hand members of well lid frame forms first inclined plane 21, leans out at the right-hand member outer wall of well lid 1 and forms second inclined plane 12, forms third inclined plane 13 at the left end outer wall leanin of well lid 1, first inclined plane 21 and second inclined plane 12 mutually support and make things convenient for well lid 1 to upwards rotate.

When the manhole cover is used, the manhole cover 1 is rotatably connected with the manhole cover frame 2, then the manhole cover frame 2 is arranged on the bottom frame 3 and is positioned through the positioning convex edge 21, and the manhole cover 1 is supported on the bottom frame 3 when closed; when the well lid 1 needs to be opened, a constructor only needs to rotate the well lid, the rotated well lid is abutted against the inner wall of the well lid frame 2, the well lid 1 inclines rightwards to prevent toppling, and the well lid 1 is convenient to open; when severe heavy rainfall weather such as heavy rain occurs, the well cover cannot be washed away, the risk of falling into the well cannot occur, and the well cover 1 is rotatably connected with the well cover frame 2 and is not easy to be stolen; simple structure and convenient installation.
