Detailed Description

The following will make a clear and complete description of the water tank molded tensile reinforced manhole sealing cover of the present invention with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the invention.

As shown in fig. 1 and 2, the utility model provides a water tank mould pressing tensile reinforced manhole sealing cover, which comprises a manhole cover body 1, wherein the manhole cover body 1 comprises a supporting body 11, a top cover 12 and an annular flanging 13, wherein the top cover 12 and the supporting body 11 are integrally formed; the support body 11 is cylindrical, a cavity 111 matched with the water tank manhole is arranged inside the support body 11, and the height of the cavity 111 is consistent with that of the water tank manhole. When the water tank manhole cover is used, the support body 11 is buckled on the outer side of the water tank manhole, at the moment, the inner side wall of the support body 11 is completely attached to the outer side wall of the water tank manhole, and the opening end of the water tank manhole is completely covered with the inner side surface of the upper end of the support body 11; thereby having good sealing function to the manhole of the water tank.

The middle part of the upper end of the support body 11 protrudes upwards to form the top cover 12, the top cover 12 is arranged into an inverted bowl-shaped structure, the maximum diameter of the top cover 12 is four fifths of the diameter of the cavity 111, and the top cover 12 is communicated with the cavity 111; the upper end of the top cover 12 is a plane, the upper end of the top cover 12 is fixedly connected with a handle 2 through a bolt 3, the handle 2 is in an inverted U shape, fixing plates 21 are symmetrically arranged on the left side and the right side of the handle 2, the fixing plates 21 and the handle 2 are integrally formed, a positioning hole 211 is formed in the fixing plate 21, and a bolt 3 hole is formed in the position, corresponding to the positioning hole 211, of the top cover 12; in addition, in order to avoid water leakage at the connection between the handle 2 and the top cover 12, a waterproof gasket (not shown) is additionally arranged between the fixing plate 21 of the handle 2 and the top cover 12; when fixing handle 2, use bolt 3 to pass from up down in proper order top cap 12, waterproof gasket and locating hole 211 use the nut to fix at last.
