Window system

Abstract

The invention discloses a window opening system which comprises connecting ropes, a window, automatic window opening mechanisms and a manual window opening mechanism. The window can be opened and closed by the connecting ropes. Each automatic window opening mechanism comprises a window opener, a retractable rod and a guide rail fixed on a keel. The retractable rods are positioned in the window openers. One end of each retractable rod is fixed on the corresponding wind opener while the other end of the same is connected with a hinge ring. Each hinge ring is fixed on a guide sliding sleeve. The guide sliding sleeves sleeve the guide rails respectively. The manual window opening mechanism comprises a manual winch. The upper ends of the connecting ropes are connected with the window after the upper portions of the connecting ropes wind second deflecting pulleys, the lower ends of the connecting ropes are connected to the manual winch after the lower portions of the connecting ropes wind first deflecting pulleys, and the middles of the connecting ropes penetrate the hinge rings. The window opening system has the advantages that the window can be opened normally in a normal or abnormal state, and the window opening system is simple in structure, low in cost and small in occupied space.

Description

technical field [0001] The invention relates to the technical field of construction devices, in particular to a window opening system. Background technique [0002] A large number of fire cases at home and abroad show that among the many factors leading to death, smoke poisoning and suffocation account for the majority. For this reason, there have been some automatic smoke exhaust windows that can be opened automatically when a fire takes place. For example, the Chinese invention patent whose notification number is CN101818609A: fire-fighting automatic smoke exhaust window and the Chinese utility model patent whose notification number is CN202073461U: electric natural smoke exhaust window all disclose the related technology of automatic window opener. However, although the above-mentioned technology can solve the problem of opening the smoke exhaust window under normal conditions, under abnormal conditions, such as abnormal fire signal, abnormal fire power supply, and mecha...

AI Technical Summary

Problems solved by technology

However, although the above-mentioned technology can solve the problem of opening the smoke exhaust window under normal conditions, under abnormal conditions, such as abnormal fire signal, abnormal fire power supply, and mechanical and electrical obstacles of the equipment itself, the smoke exhaust window may appear. The opening is not normal or even can not be opened at all

Even though there are currently smoke exhaust windows that can be opened under abnormal conditions, most of the smoke exhaust windows have complex structures and greatly affect the indoor space, thereby hindering the promotion of technology
