Plastic-steel door and window assembly plug-in connector

Abstract

The invention discloses a plastic-steel door and window assembly plug-in connector which comprises a random main connector, two random waterproof positioning connectors, steel reinforcing sheets and fixing screws. The shapes of the cross sections of two ends of the random main connector are matched with those of the cross sections of assembly profiles, the insides of the two ends of the random main connector are hollow, the two ends of the random main connector are inserted into the profiles on two sides and closely connected in a seamless manner, the two random waterproof positioning connectors are opposite in direction and arranged on two sides of the middle of the random main connector, projections matched with internal structures on two sides of the assembly profiles are arranged on the random waterproof positioning connectors, waterproof positioning of the assembly profiles on two sides is realized, the steel reinforcing sheets are embedded into side faces of the two ends of the random main connector, and holes formed in the corresponding steel reinforcing sheets outside the profiles are fixed by the screws after the assembly profiles on the two sides are connected in an inserted manner. The plastic-steel door and window assembly plug-in connector is applicable to assembly of plastic-steel sashes, window frames, mullions and window frames, and is simple in structure and strong in universality. Angular strength is improved, and assembly parts are small in occupied space and convenient to transport and mount.

Description

technical field [0001] The invention relates to the field of installation of plastic-steel doors and windows, in particular to an assembly plug-in for plastic-steel doors and windows. Background technique [0002] At present, plastic steel doors and windows are recognized by the majority of users for their advantages such as heat preservation, sound insulation, and good sealing effects. Therefore, most users will prefer plastic steel when choosing door and window profiles. At present, there are 9 processing procedures for plastic steel doors and windows, which are material cutting, milling, lining steel cutting, lining steel assembly, fan welding, fan corner cleaning, frame welding, frame corner cleaning, assembly, and quality inspection. There are certain defects in this kind of processing procedure. For example, there is no lining steel at the welding angle of the window sash and the window frame, resulting in poor angle strength, and the surface of the welding angle needs...
