Modular multi-layer heat insulation plastic-steel door and window

Abstract

The invention discloses a modular multi-layer heat insulation plastic-steel door and window, and belongs to the technical field of plastic-steel doors and windows. The modular multi-layer heat insulation plastic-steel door and window comprises an upper frame, a first door and window body, a second door and window body, a bottom frame, a mounting assembly, a sliding assembly and an oil coating assembly, wherein the first door and window body and the second door and window body are slidably installed between the upper frame and the bottom frame, a built-in oil box is fixedly installed in the upper frame, and pulley grooves are formed in the tops of the first door and window body and the second door and window body. According to the modular multi-layer heat insulation plastic-steel door and window, a track which can be quickly disassembled is installed inside, so that when the track is deformed or damaged, two moving shafts can be directly extruded to drive side connecting shafts to displace, so that the side connecting shafts are separated from connecting positioning holes, at the moment, connecting springs lose limiting force, a mounting plate can be automatically pulled back, therefore, mounting and positioning release of the track can be effectively and quickly completed, at the moment, the track can be quickly disassembled by directly laterally moving the track, the track is quickly overhauled or replaced, and the using effect of the whole door and window is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of plastic-steel doors and windows, in particular to a modular multi-layer heat-insulating plastic-steel door and window. Background technique [0002] 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. frame fan. [0003] Chinese patent discloses (CN202020041709.7) plastic-steel doors and windows with good lighting performance, including plastic-steel door and window frames, lighting glass is fixedly installed on the top of the plastic-steel door and window frames, and light-transmitting panels are fixedly installed on the bottom of the plastic-steel door and window frames. The outer surface of the frame is made of smooth material. The outer surface of the plastic steel door and wi...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the traditional plastic-steel doors and windows are not equipped with any heat insulation layer, resulting in poor overall internal heat insulation performance of the plastic-steel doors and windows At the same time, the slide rails of plastic steel doors and windows cannot be disassembled. If there is damage, it will cause the problem that the overall doors and windows are difficult to slide. A modular multi-layer heat-insulating plastic steel doors and windows is proposed
