Detailed Description
In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
As shown in fig. 1 and 2, the embodiment of the present invention provides a quick opening and closing manhole cover device, including: the device comprises a short section 1, a first support 2, a second support 10, an outer gland 5, an inner gland 6 and a cover plate 3.
The short section 1 is welded on the access hole; the short section 1 is adaptive to the shape of the access hole; one end of the short section 1 is provided with a first support 2, and the other corresponding end is provided with a second support 10;
articulated interior gland 6 on the first support 2, specifically, interior gland 6 is connected through first rotation axis 9 to first support 2. One end of the inner gland 6 far away from the first rotating shaft 9 is provided with an arc-shaped bulge. The inner side of the inner gland 6 is provided with a cover plate 3; the cover plate 3 is matched with the nipple 1 in shape, the sealing gasket 4 is circumferentially arranged on the inner side of the cover plate 3, and a good sealing effect is guaranteed under the pressing state of the cover plate 3. Specifically, the inner gland 6 is provided with the cover plate 3 through an adjusting chain bolt 7 and a nut 8. And a sealing ring is arranged between the nut 8 and the cover plate 3. One end of the adjusting chain bolt 7 is welded on the inner gland 6, one end of the adjusting chain bolt uses the nut 8 to clamp and fix the cover plate 3, and the distance between the cover plate 3 and the inner gland 6 can be adjusted by adjusting the installation position of the nut 8, so that the pressing force of the cover plate 3 can be adjusted.
