Heavy six-link 180-degree casement hinge

Abstract

The invention discloses a heavy six-link 180-degree casement hinge, and relates to hardware of doors and windows. The casement hinge comprises a groove-shaped bottom plate connected with a window frame, a starting connecting rod connected with a window sash, a long connecting rod, a short connecting rod, a long supporting connecting rod, a middle supporting connecting rod and a short supporting connecting rod, wherein the long connecting rod and the short connecting rod are riveted to the starting connecting rod, the long supporting connecting rod, the middle supporting connecting rod and theshort supporting connecting rod are riveted to the long connecting rod and the groove-shaped bottom plate respectively, and an opening and closing structure composed of nine rivet shafts is formed. According to the casement hinge, the thickness of the connecting rods is increased, and a riveting connection structure is used, so that the bearing capacity is improved; all parts are made of metal materials, and all functions of the hinge do not fail even under the condition of high temperature, so that the fire safety is guaranteed; and the window sash is driven to rotate through the rivet shaft,and extra movement space does not need to be increased, so that screws can be screwed at the groove-shaped bottom plate, the groove-shaped bottom plate is fixed to the window frame, and installationand connection are firm, and therefore, the load-bearing, anti-theft, fire-fighting and installation functions are greatly improved, and safety guarantee is provided for installation and use of a user.

Description

technical field [0001] This application relates to door and window hardware accessories, in particular to a heavy-duty six-link 180° 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, resulting...

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
