Problems solved by technology

[0002] Among the existing window closers, most of them are suitable for fire-resistant windows, but not for fire-resistant windows. Now most of the public areas (schools, communities, hospitals, office areas, etc.) are mostly used Fire-resistant windows, and the high frequency of fires occurs in these public areas with a large number of people. When a fire occurs, among the many factors that affect the size of the fire, the fluidity of indoor and outdoor air often affects the size of the fire. Therefore, in order to prevent In the event of a fire, the fire will increase due to the opening of the window. To design a window closer suitable for aluminum alloy fire-resistant windows

Abstract

The invention discloses a window closing device for an aluminum alloy fire-resistant window. According to the window closing device, a limiting block and a folding block are punched on a small sliding plate at the same time through the integrated punching technology, a square hole is reserved, a blasting bead fixing block is placed in the square hole and a square hole formed in a sliding groove, when a fire disaster occurs and a certain temperature is reached, an arranged temperature sensing glass ball explodes, When the window is opened, the blast bead fixing block falls from the two square holes, a tension spring pulls the small sliding plate to drive s window sash to be closed, indoor air circulation is rapidly reduced, and the situation that the fire behavior is increased due to flowing of indoor air and air outside the window is prevented.

Description

technical field [0001] The invention belongs to the field of door and window structures, and in particular relates to an aluminum alloy fire-resistant window closer. Background technique [0002] Among the existing window closers, most of them are suitable for fire-resistant windows, but not for fire-resistant windows. Now most of the public areas (schools, communities, hospitals, office areas, etc.) are mostly used Fire-resistant windows, and the high frequency of fires occurs in these public areas with a large number of people. When a fire occurs, among the many factors that affect the size of the fire, the fluidity of indoor and outdoor air can often affect the size of the fire. Therefore, in order to prevent In the event of a fire, the fire will increase due to the opening of the window, so a window closer suitable for aluminum alloy fire-resistant windows is designed. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present inventio...
