Multi-purpose stainless steel door and window corner device

Abstract

The invention discloses a multipurpose stainless steel window and door corner device, which comprises a 90-degree bent housing and a corner transmission mechanism arranged inside the housing, wherein the housing is formed by cold bending of stainless steel belts; the corner transmission mechanism comprises a first connection mechanism, a transmission belt and a second connection mechanism made of stainless steel, the upper end of the transmission belt is connected with the first connection mechanism, the lower end of the transmission belt is connected with the second connection mechanism, the first connection mechanism is arranged at the horizontal part of the housing in a sliding connection manner, the second connection mechanism is arranged at the vertical part of the housing in a sliding connection manner, the first connection mechanism is used for connecting a diagonal tension rod component in an internal flat-opening lower suspending system of an European standard aluminum alloy window or an internal flat-opening lower suspending system of a U-type notched plastic steel window, and the second connection mechanism is used for connecting an internal opening transmission rod component in the internal flat-opening lower suspending system of the European standard aluminum alloy window or the internal flat-opening lower suspending system of the U-type notched plastic steel window. The multipurpose stainless steel window and door corner device is integrally made of stainless steel, is simple in structure, convenient to install, high in strength, long in service life and good in generality.

Description

technical field [0001] The invention relates to a door and window hardware fitting, in particular to a multi-purpose stainless steel door and window corner. Background technique [0002] The corner device is one of the commonly used hardware accessories for doors and windows. It is usually installed at the corner of the window sash. It is used to connect other hardware on the two sides of the window sash to realize the linkage of the door and window hardware system and complete the opening of the window sash. At present, the inner swing and lower suspension system of the door and window hardware industry generally includes the inner swing and lower suspension system of the European standard aluminum alloy window and the inner swing and lower suspension system of the U-shaped notch plastic steel window. The device is made of zinc alloy, and the corner device of the U-shaped notch plastic steel window is made of ordinary iron plate, and the zinc alloy and iron have poor surfac...

AI Technical Summary

Problems solved by technology

At present, the swing and hang system in the door and window hardware industry generally includes the swing and hang system for the European standard aluminum alloy window and the swing and hang system for the U-shaped plastic steel window. The device is made of zinc alloy, and the corner device of the U-shaped notch plastic steel window is made of ordinary iron plate, and the zinc alloy and iron have poor surface tolerance due to their own characteristics. Under the erosion of water, defects such as corrosion, rust, and strength reduction will occur

Especially in coastal cities, due to the high humidity and salt content in the air, the corner fittings are easily corroded and their strength is greatly reduced, which shortens the service life of the entire door and window hardware system

In addition, due to the influence of the structural characteristics of European standard aluminum alloy windows and U-shaped notch plastic-steel windows, the European standard aluminum alloy windows can only use special corners for European standard aluminum alloy windows. Plastic-steel window inner casement and down-hung system can only use special corners for U-shaped notch plastic-steel windows. Different corners cannot be used universally, which affects its scope of use and installation operation. It can be seen that the existing corners have certain applications. limitations on
