Abstract

The invention discloses a fireproof window closing device. The fireproof window closing device comprises a swing rod, a first assembly and a second assembly, wherein the first assembly and the second assembly are hinged to the two ends of the swing rod correspondingly; the first assembly and the second assembly are further connected with a window sash and a window frame correspondingly; the first assembly comprises a base, a first sliding block in interaction fit with the base, and a temperature control window closing mechanism driving the first sliding block to slide; a rack is formed on the first sliding block, and meanwhile a gear engaged with the first sliding block is formed at the end of the swing rod; the temperature control window closing mechanism is provided with a temperature sensing unit; and when the temperature sensing unit bursts, the temperature control window closing mechanism drives the first sliding block to slide so as to drive the swing rod to swing in the window sash closing direction.

Description

technical field [0001] The invention relates to the technical field of building hardware accessories, in particular to a fireproof window closing device. Background technique [0002] For building doors and windows, when a fire occurs, fireproof windows play an important role in preventing major losses in the event of a fire, slowing down the spread of fire, including open flames, high temperatures, and dense smoke, and buying time for fire rescue. The windows of many buildings are equipped with ordinary hinges without fire-proof automatic window closing components; after the existing fire-proof automatic window closing components on the market are installed, the windows have resistance to opening, and the elderly and children need a lot of effort to open them. window. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a fireproof window closing device with a novel and reliable structure that...
