Abstract
The utility model discloses a firmly installed thread cover plate which comprises a ring-shaped cover plate body, wherein a thread centre hole which back extends toward a filter installation base is arranged in the center of the cover plate body. A ring-shaped outer edge portion of the cover plate body is a straight flat open portion, an inclined transition portion is arranged between the flat open portion and the upper portion of the thread center hole, and filter holes are distributed in the transition portion. A compression-resisting layer is arranged on the upper surface of the cover plate body, and a ring-shaped shallow groove, corresponds to the edge of the filter installation base, is formed in the front face of the flat open portion of the cover plate body. The firmly installed thread cover plate is simple in structure, and reasonable in design. The ring-shaped groove is formed in the front face of the flat open portion, so that the filter installation base is firmly installed, and good in sealing, and improves compression resisting ability of the thread cover plate, and meets the use demand of an enterprise.
