Friction hinge installed and connected with window frame

Abstract

The invention relates to a friction hinge installed and connected with a window frame. The friction hinge installed and connected with the window frame comprises a hinge plate and a linkage assembly,wherein the hinge plate is fixed onto a C-shaped groove of the window frame, and comprises a sinking seat; the sinking seat is arranged in the C-shaped groove and is fixed through a screw; two symmetrical sliding seats are arranged on two sides of the top end of the sinking seat; two sides of the C-shaped groove extend to form shoulder parts for load-bearing the two sliding seats; and a sliding chute is formed in each sliding seat. According to the structure, when a wider hinge plate is installed on the window frame, a groove wall on one side of the C-shaped groove has no need to be cut off, the friction hinge can be applied to the window frame with any C-shaped groove width, and the installation speed of the hinge can be accelerated, so that the time and the labor are saved, the firmnessin installation is realized, and the structure firmness of the window frame can be protected.

Description

technical field [0001] The invention relates to the field of friction hinges, in particular to a friction hinge installed and connected with a window frame. Background technique [0002] Today's windows can be turned around the vertical axis through hidden hinges. In the window frame structure, the window frame is composed of multiple standard aluminum materials, and each aluminum material has multiple C-shaped concave holes of standard width. The groove is convenient for window manufacturers to install friction hinges. However, since the width of the C-shaped groove is fixed, friction hinges can only use hinges with narrower hinge plates. Therefore, traditional hinges can only be installed on windows with lower weight. When the window is heavy, the manufacturer needs to install a hinge with a wider hinge plate.

[0002] Today's windows can be turned around the vertical axis through hidden hinges. In the window frame structure, the window frame is composed of multiple standard aluminum materials, and each aluminum material has multiple C-shaped concave holes of standard width. The groove is convenient for window manufacturers to install friction hinges. However, since the width of the C-shaped groove is fixed, friction hinges can only use hinges with narrower hinge plates. Therefore, traditional hinges can only be installed on windows with lower weight. When the window is heavy, the manufacturer needs to install a hinge with a wider hinge plate. Therefore, when installing the hinge, the groove wall on one side of the C-shaped groove must be cut off so that the hinge can be installed at the bottom of the C-shaped groove. This method is difficult to install. Removing the groove wall is time-consuming and laborious, and it will damage the original structure of the window frame and reduce the installability of the window frame. In order to facilitate the friction adjustment screw on the hinge to press against the hinge plate, when the hinge is installed, it can only be installed at both ends of the hinge plate. The upper part is fixedly connected with the window frame through fasteners. Fasteners cannot be installed in the middle part of the hinge that bears most of the weight of the window and door to facilitate the sliding of the friction adjustment screw, so that the middle part of the hinge bears a large force. When repeated for a long time It is easy to cause damage and deformation of the hinge, reduce the service life of the hinge, and cause the safety accident of the window falling
