Combined transition slider and its included external louver control assembly, external louver glass window

By using the staggered design of the combined transition slider, the first and second transition sliders are respectively attached to the louver traction slider and the inner control slider, which solves the problem of insufficient magnetic attraction and achieves smooth operation of the triple-glazed, double-cavity louver.

AI Technical Summary

Technical Problem

In the existing technology, the transition slider of the triple-glazed double-cavity hollow venetian blind has insufficient magnetic attraction due to the limited thickness of the magnet, which makes it impossible to effectively control the opening and closing of the venetian blind. Especially when it is installed in the outdoor cavity, the magnetic attraction between the inner control slider and the venetian traction slider is difficult to achieve smooth operation.

Method used

A combined transition slider is adopted. The first and second transition sliders are snapped together and staggered to attach to the louver traction slider and the internal control slider respectively. The two sliders are attracted by permanent magnets on opposite sides to achieve overall linkage and meet the magnetic force requirements.

Benefits of technology

It achieves smooth control of the venetian blinds in the outer cavity of the triple-glazed, double-cavity blinds, avoiding the space limitations caused by thickening the magnets, and ensuring sufficient magnetic force and smooth operation.

Abstract

This utility model discloses a combined transition slider and an external louver control assembly and an external louvered glass window containing it. The combined transition slider includes a first transition slider and a second transition slider that snap together. Both the first and second transition sliders include a strip-shaped body with rollers rotatably connected to both ends. A mounting groove is formed in the middle of the body, and a permanent magnet is installed in the mounting groove. One end of the first transition slider is connected to a buckle, and one end of the second transition slider has a groove that matches the outline of the buckle. The buckle is movably engaged in the groove, connecting the first and second transition sliders end to end. The permanent magnets on the first and second transition sliders are on opposite sides. When this combined transition slider is installed on a triple-glazed, double-cavity external louvered glass window, the first and second transition sliders only individually attract the louver traction slider and the internal control slider, respectively. The magnetic force is sufficient, and the two sliders work together to achieve a transition traction effect.
