Safety shutter

Abstract

The invention discloses a louver security window, which is made up of window outer frame, window sash, and lock, the window sash includes side frame, louver, louver spindle, louver position limiting component and louver adjusting component. The invention uses louver spindle and position limiting component to bond the louver and the outer frame together, when the louver is acted by the external force, the external force is changed into pulling force and transmitted to the side frame through the louver spindle and the position limiting device, and the louver spindle will not disengage from the side frame, thus the whole window sash can resist the external force. The position limiting component restrains the movement of the louver spindle, and it does not affect its rotation, the gear on each louver spindle engages with the gear rack or gear belt, toggling one piece of louver can make all the louvers rotate with any angle.

Description

Technical field [0001] The invention relates to a safety protection component for building windows, in particular to an openable 100-page safety protection window. Background technique [0002] At present, all kinds of buildings use welded steel mesh cages for window opening safety protection. Although it can prevent outsiders from entering and leaving, it also has problems of blocking sight and affecting the appearance of building facades, especially in emergency situations such as fires. The problem that it is difficult for people in the lower room to escape through the window hole and hinder external rescue is prominent. There is a kind of commercialized safety roller blind in foreign countries. The louver sheet is composed of an alloy or plastic outer layer and an inner filling insulation sandwich layer. It has the characteristics of labor-saving opening, simple appearance, and heat insulation. The rear curtain cannot be rotated, which completely blocks the light, and t...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of existing safety protection windows in the market that cannot be opened or fully opened, single function, and the louver of the safety roller blind cannot be rotated and adjusted, and provide a simple structure, convenient and flexible regulation, and fully openable window sash. The 100-page sheet can adjust the angle arbitrarily, and has a safety protection window that integrates functions such as sunshade, light and air volume control, and noise isolation and noise reduction.
