Description
Technical field
The utility model belongs in the door and window hinge uses gum cover, is specifically related to a kind of door and window supporting hinge side gum cover.
Background technology
The hinge that is used in prior art above the door and window bin is the hinge that is made of two metals, and the hinge of using on recent door and window is a design plastics gum cover between hinge axle and rachis hole, cut off the potential difference of hinge axle and hinge metal and the sassafras that directly rubs each other, reach anticorrosion, the effect of antifriction sassafras.The support-side of hinge is equipped with gum cover.A kind of gum cover is the gum cover of two-part hinge, and the shaped core of injection mold is the overhanging beam structure normally, makes shaped core inevitable crooked because the directionality and the pressure of glue are advanced in injection moulding, causes coaxiality error.When hinge used, the sash arrisdefect directly influenced door and window and opens and closes.Another kind of core is a tube girder construction, becomes core to run through the front and back mold cavity and overlap, but gum cover has seepy question, has both made the increase waterproof cover, because in the outdoor application process, four seasons temperature difference influence, waterproof cover can come off voluntarily.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned defective, the door and window supporting hinge side gum cover of the good energy of a kind of axiality waterproof being provided.
For realizing purpose of the present invention, technical scheme of the present invention is: a kind of door and window supporting hinge side gum cover, gum cover body front end is uncovered, the bottom is closed, it is characterized in that: the end face of bottom is concave station, boss in the form of a ring around concave station, there is a core hole at the center, and is stamped and the plug bottom of concave station, annular boss and core hole kissing is welding.
Advantage of the present utility model: the good concentricity of gum cover, safe and reliable, there is not the problem of leaking and needing waterproof.
