Abstract

The invention discloses a frication hinge, which comprises a frame fixed plate, a supporting plate, a sash fixed plate, a middle supporting plate, a sliding supporting plate, a strip sliding block, a hinged shaft and a spring, wherein the sash fixed plate is right-angled, and a vertical shaft of the sash fixed plate is hinged with the supporting plate; the other end of the supporting plate is hinged with the frame fixed plate, the supporting plate is provided with an open slot, and a positioning inclined plane is arranged in the open slot; a horizontal supporting plate of the sash fixed plate is hinged with one end of the sliding supporting plate; the end of the sliding supporting plate is provided with a locking inclined plane, and the other end of the sliding supporting plate is hinged with the strip sliding block in a strip slot of the frame fixed plate; one end of the middle supporting plate is hinged with the frame fixed plate, and the other end of the middle supporting plate is hinged with the middle part of the sliding supporting plate; when the frication hinge is closed, the supporting plate, the sash fixed plate, the sliding supporting plate and the middle supporting plate are in linkage hinged deformation; and the end of the sliding supporting plate enters the open slot of the supporting plate, the locking inclined plane at the end of the sliding supporting plate is pressed on the positioning inclined plane of the supporting plate, and the other end of the sliding supporting plate drives the strip sliding block to move along the strip slot of the frame fixed plate.

Description

Technical field: [0001] The invention relates to a friction hinge for doors and windows. Background technique: [0002] The fan fixing part of the existing friction hinge is flat plate, the fan fixing part is fixed in the horizontal direction, and there is no vertical shaft in the vertical direction, the connecting hinge shaft is easily damaged, and the bearing capacity is small. [0003] One end of the existing friction hinge support plate is connected to the sliding piece, and one end of the long support plate is hinged to the frame connecting plate. The support plate has no positioning slope, and the end of the sliding support plate has no locking slope. When the friction hinge is closed, the friction hinge cannot Accurate positioning and locking. The existing friction hinge does not have a positioning mechanism for the window sash to stay in any position. Invention content: [0004] The purpose of the present invention is: 1, the fan fixing part is designed to be rec...
