Detailed Description

Fig. 1 shows the main technical content of the present embodiment, and a waterproof plastic manhole cover comprises a cover body 1, a preformed hole 2 and a handle 3, wherein the handle 3 is arranged on the outer surface of the cover body 1, the preformed hole 2 is arranged at the edge of the cover body 1, and a waterproof ventilating screw 4 is connected to the preformed hole 2 through a thread.

Fig. 2 and fig. 3 show the concrete structure of waterproof ventilative screw 4, nut 5 radially opens has many through holes, nail body 6 is hollow structure, and separate waterproof ventilated membrane 8 between the radial through hole on the nut 5, waterproof ventilated membrane is commonly called breathing membrane, it is more ripe prior art, when guaranteeing that the radial through hole that the air passes through nut 5 gets into the cavity passageway of nail body 6 and then get into the plastics inspection shaft, can be fine again prevent the outside hydrone of plastics inspection shaft well lid to get into the well body, during the use, through the screw-thread fit between nail body 6 and preformed hole 2, firm screwing is to the well lid surface, in order to prevent outside water from the clearance seepage inflow of waterproof ventilative screw 4 and well lid contact surface, sealing washer 7 has still been cup jointed at the surface of nut 5 and the junction of nail body 6, reach waterproof ventilative effect with this mode.

Further, in order to prevent the vent holes of the waterproof ventilating screws 4 from being blocked accidentally, two waterproof ventilating screws 4 are specially arranged and are symmetrically arranged on two sides of the handle 3.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
