90-degree side-hung hinge for heavy triple rod

Abstract

The invention discloses a 90-degree side-hung hinge for a heavy triple rod, and relates to hardware of doors and windows. The side-hung hinge comprises a U-shaped bottom plate connected with a windowframe, a starting connecting rod connected with a window sash, a long supporting connecting rod and a short supporting connecting rod, wherein the long supporting connecting rod and the short supporting connecting rod are riveted with the U-shaped bottom plate and the starting connecting rod correspondingly, and an opening and closing structure composed of four rivet shafts is formed. Through a riveting structure, the thickness of the connecting rods is increased, and in addition, a riveting connection structure is used, so that the bearing capacity of the 90-degree side-hung hinge is improved; all parts of the 90-degree side-hung hinge are made of metal materials, all functions of the 90-degree side-hung hinge do not fail even under the condition of high temperature, and fire safety is guaranteed; the window sash is driven to rotate through a rivet shaft, extra movement space does not need to be increased, screws can be driven at the U-shaped bottom plate, the U-shaped bottom plate and the window frame are fixed, and mounting and connection are firm; and therefore, the load-bearing, anti-theft, fire-fighting and mounting functions are greatly improved, and the safety guarantee isprovided for mounting and using by a user.

Description

technical field [0001] This application relates to door and window hardware accessories, in particular to a heavy-duty three-link 90° casement hinge. Background technique [0002] With the development of scientific and technological progress, many traditional door and window hardware accessories products on the market have begun to improve and innovate. For example, the hardware accessories used for windows on the market are sliding stays. There are various styles of sliding stay hinges on the market, and all of them realize the opening and closing of the window sash through the movement of linkages, sliders, and chutes. [0003] The above-mentioned structure limits the thickness of the connecting rod, which seriously affects the load-bearing strength of the window sash. The above-mentioned structure makes the installation of the chute also limited. Since the slider needs to move in the chute, screws cannot be installed in the chute to fix it with the window frame, resultin...

AI Technical Summary

Problems solved by technology

[0003] The above structure limits the thickness of the connecting rod, which seriously affects the load-bearing strength of the window sash

The above structure also restricts the installation of the chute. Since the slider needs to move in the chute, it is impossible to install screws in the chute to fix the window frame, resulting in safety hazards such as weak installation and connection.

Sliders are made of plastic, which can lead to failure at high temperatures

Therefore, there are deficiencies in load-bearing, anti-theft, fire protection, and installation problems in the existing sliding brace structure
