Novel upper suspension window air brace

Abstract

The invention relates to the technical field of air braces, and discloses a novel upper suspension window air brace. The air brace comprises a window sash, a supporting plate, a window cabinet and a long plate, wherein the front surface of the window cabinet is fixedly connected with a supporting plate, the inner side wall of the supporting plate is in sliding connection with a sliding piece, theupper part of the front surface of the sliding piece is rotatably connected with a first metal strip, one side of the first metal strip is rotationally connected with a second metal strip, and one side of the second metal strip is rotationally connected with a third metal strip; and a fixing block is added between two sliding rails, the fixing block is fixed on the sliding rails, a convex plate isadditionally arranged on the front surface of the sliding plate, the convex plate is fixed with the sliding plate, and the convex plate slips relative to the sliding rails, when the sliding plate isstressed to slide, the convex plate can be attached to one side of the fixing block, the convex plate can define the position of the sliding plate, the fixing block abuts against the convex plate, when the window sash is opened, the sliding plate can be prevented from being separated from the sliding rails, and the using effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of wind braces, in particular to a novel top-hung window wind brace. Background technique [0002] The wind brace is also called the two-linkage, which connects two independent things to fix, stabilize or limit the position. The wind brace has a wide range of uses. For example: make the window sash open to a certain angle as required, and limit the window sash to swing freely due to wind pressure. There are two types of sliding stays, one is for casement windows, also known as four-bar linkage in the industry, which plays the role of load-bearing and position-limiting; the other is for hanging windows, which plays the role of load-bearing. In the tie-arch bridge, wind braces are used to connect the main arches on both sides to maintain the integrity and stability of the main arches. [0003] There are following problems in existing technology: [0004] (1) When the device supports the opening of the sash,...

AI Technical Summary

Problems solved by technology

[0004] (1) When the device supports the opening of the sash, the sliding plate slides out in the slide rail. Sometimes when the user uses too much force to open the sash, the sliding plate is easy to detach from the slide rail, which affects the use of the device;

[0005] (2) When the window sash is closed...
