Abstract

A frictional hinge comprises a frame fixing plate, a support plate, a sash fixing plate, a middle support plate, a sliding support plate, a sliding block, a hinged shaft and a spring, wherein the sash fixing plate is right-angled; a locking column of the sliding support plate is arranged on a horizontal support plate of the sash fixing plate; a vertical shaft sleeve is arranged on the vertical fixing plate of the sash fixing plate and articulated with the support plate; the other end of the support plate is articulated with the frame fixing plate; the support plate is provided with an open slot internally provided with a positioning and locking surface; the horizontal support plate of the sash fixing plate is articulated with one end of the sliding support plate; the end part of the sliding support plate is provided with a locking push plate matched with the shape of the positioning and locking surface of the support plate; a locking slot is arranged at the middle part of the sliding support plate; the other end of the sliding support plate is articulated with the sliding block in the frame fixing plate; one end of the middle support plate is articulated with the frame fixing plate; the other end of the middle support plate is articulated with the middle part of the sliding support plate; when the frictional hinge is closed, the support plate and the right-angled sash fixing plate, the sliding support plate and the middle support plate are in linked and articulated deformation, the locking column of the sliding support plate on the horizontal support plate of the sash fixing plate enters the locking slot at the middle of the sliding support plate; the locking push plate at the end part of the sliding support plate enters the open slot of the support plate; the locking push plate is pressed on the positioning and locking surface of the support plate; and the other end of the sliding support plate drives the sliding block to move along the frame fixing 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 fixing 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 rectang...
