Theft-proof plastic steel window

Abstract

The invention relates to the technical field of building windows, and discloses a theft-proof plastic steel window. The window comprises a plastic steel window frame, a movable groove is formed in thebottom of the plastic steel window frame, and a sliding groove penetrating through the upper end of the inner wall of the plastic steel window frame and communicated with the movable groove is formedin the upper surface of the inner wall of the plastic steel window frame; a first bearing is fixedly connected to the upper surface of the inner wall of the movable groove, a first round rod is fixedly connected with the inner wall of the first bearing, and the surface of the first round rod is movably connected with the inner wall of the sliding groove, and a first plastic steel window is fixedly connected with the upper surface of the first round rod. According to the theft-proof plastic steel window, a connecting block is pushed to make the first plastic steel window rotate by taking a second round rod as the circle center, the first plastic steel window cooperates with a second plastic steel window by taking a third round rod as the circle center to rotate so that the first plastic steel window and the second plastic steel window can be folded, and therefore the purposes of thievery prevention and large ventilating areas are achieved.

Description

technical field [0001] The invention relates to the technical field of building windows, in particular to an anti-theft plastic-steel window. Background technique [0002] Plastic-steel windows are a form of windows that were actively promoted by the state in the mid-1990s after wood, iron, and aluminum alloy windows. Because of its low price and relatively good performance and price, it is still widely used. The frame of this kind of window is made of polyvinyl chloride resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., extruded into materials; it is one of the most commonly used types of windows in modern buildings. [0003] Plastic steel doors and windows are made of polyvinyl chloride resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., extruded into profiles, and then made into doors and windows by cutting, welding or screwing. ...
