As a further arrangement of the utility model, the water retaining ring of the well seat is provided with a pair of hook portions which are arranged at intervals and concave towards the center. The escalator can be conveniently hooked on the water retaining ring by arranging the hooking part which is concave inwards towards the center, so that the escalator can be conveniently hooked up and down by people.

As the utility model discloses a further setting, well seat appearance outline and manger plate circle shape are the rectangle, the seat circle mouth of well seat is circular, seat circle mouth diameter is less than manger plate circle diagonal length, four bights are equipped with the connection screw in the manger plate circle, one side and the articulated connection of well seat of well lid body, the opposite side of well lid body is equipped with lock core and locking brake mechanism. According to the well lid, the connection screw holes are formed in the four corners in the water retaining ring, the well base is fixedly connected with the oil storage tank or the manhole operation well through the connection screw holes, the well lid body is covered and locked by the locking mechanism for protection, a person stealing oil is difficult to steal directly by detaching the fixing nut and the bolt, and the anti-theft performance is improved.

As a further setting of the utility model, be equipped with the air spring between well lid body and the well seat. The gas spring is arranged, so that the function of assisting in opening the well cover can be achieved, and the well cover can be opened conveniently; provide certain damping force when closing, prevent to make well lid body and well seat bump and send the noise or lead to damaging because well lid dead weight or power reason excessively.

As a further arrangement of the utility model, the well seat is provided with an annular shoulder which is arranged in a high-inside and low-outside inclined manner. The annular shoulder of the well seat is obliquely arranged with a high inside and a low outside, so that drainage can be accelerated, and water resistance is facilitated.

The invention will be further described with reference to the accompanying drawings and specific embodiments.
