Abstract
The utility model provides an empty filter gag structure of overhead that can effectively prevent that the screw from corroding and whole outward appearance is pleasing to the eye. Empty filter gag structure of overhead, including the body, the body lower surface is provided with the recess that matches with the head shape of screw, the whole shape of body matches with the shape of the heavy platform of screw hole. The plug cover is assembled after the screw of the upper shell of the air filter is screwed down, so that the corrosion of rainwater to the screw can be effectively prevented, the appearance consistency of the upper shell can be improved, and the whole body is attractive.
Description
Technical Field
The utility model relates to a gag structure especially relates to an use and improves gag structure of the whole outward appearance uniformity of high altitude filter on the empty filter of overhead that adopts the screw connection.
Background
At present, on an overhead air filter connected by screws, the overhead air filter is directly exposed in the air after being connected by the screws, rainwater is gathered at the screw mounting position of a shell on the air filter, the screws are easily corroded, and the appearance shape of the overhead air filter is lack of the integral beautifying effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an empty filter gag structure of overhead that can effectively prevent that the screw from corroding and whole outward appearance is pleasing to the eye is provided.
The utility model provides a technical scheme that technical problem adopted is: empty filter gag structure of overhead, including the body, the body lower surface is provided with the recess that matches with the head shape of screw, the whole shape of body matches with the shape of the heavy platform of screw hole.
Further, the height of the groove of the body is consistent with the height of the head of the screw.
Further, the height of the body is consistent with the depth of the sunken table of the screw hole of the upper shell.
Furthermore, the upper surface of the body is a curved surface, and the curved surface is consistent with the appearance curved surface of the upper shell.
Furthermore, the edge of the upper surface of the body is provided with a smooth fillet.
Further, the body and the sunken table of the screw hole of the upper shell have an interference fit amount of 0.2 mm.
Further, the body is made of rubber materials.
