Description

High-base hinge fixing opened angle for steel window

The utility model relates to the High-foot hinge of the steel sash the fixed opening angle that uses on a kind of steel sash, belongs to accessories for windows and doors.

Generally replace timber window on the building at present with steel sash, during unlatching, in order to prevent that external force from close sash voluntarily, on sash, fixed support bar with holes, support bar is inserted on the bearing pin of window frame, sash is fixed on the angle of unlatching, but in Steel window with double layer, easily the glass of interior sash is broken up during support bar improper use on the outer leaf, support bar is corrosion easily also, rotate dumbly, make troubles to screen window is installed summer simultaneously.

The purpose of this utility model is to provide a kind of High-foot hinge of fixedly steel sash opening angle.

The High-foot hinge of fixedly steel sash opening angle of the present utility model comprises two pages and the bearing pin that two pages are flexibly connected, and it is characterized in that processing respectively on two pages porose, is installed with an arc in the described hole.The distance in the hole that the gyroaxis that the arc radius of arc equals the page is processed to the page, be processed with groove on the lower surface of arc, arc is fixed on a slice page with bearing pin, and another sheet page can rotate along arc around its gyroaxis, also can be clamped in the groove of arc.During use, with the fixing a slice page fix of arc on window frame, can be on sash along the rotating a slice page fix of arc.When sash was opened, sash drove the page fixed thereon and turns round along arc, and when having the position of groove on being turned back to arc, arc is fallen in that the self gravitation effect is following, the page is sticked in the groove of arc, with the sash fixed-site.If close sash, then only need lift arc slightly, the page and the groove that are stuck in the groove are broken away from, then sash can be closed.

The utility model has the advantages that simple in structurely, easy to process, flexible operation can be saved great deal of steel, is convenient to install summer screen window simultaneously.
