Abstract

The invention discloses an automatic fireproof window closer, comprising a first body installed on a window frame, a second body installed on a side frame of a window, and a telescopic arm, wherein the two ends of the telescopic arm are respectively connected with the first body and the second body; the first body is provided with an elastic recovery mechanism; the telescopic arm is provided witha connecting rod, one end of the connecting rod is connected with the elastic recovery mechanism by means of a first rotating shaft, and the other end of the connecting rod is connected with the telescopic rod by means of a second rotating shaft; the second body is provided with a first sliding groove, and the first sliding groove is internally provided with a sliding seat; one end of the telescopic arm is connected with the first body by means of a third rotating shaft, and the other end of the telescopic arm is connected with the sliding seat by means of a fourth rotating shaft; the slidingseat is provided with an unlocking piece, and a temperature sensing element capable of fixing the unlocking piece; the unlocking piece is rotatably connected with the sliding seat by means of the elastic recovery mechanism; a cam part is arranged on the unlocking piece. The automatic fireproof window closer is simple in structure and small in volume, and can realize hidden installation; a mechanical mechanism of the automatic fireproof window closer is stable, reliable and high in sensitivity.

Description

technical field [0001] The invention relates to the technical field of fire prevention equipment, in particular to an automatic fire prevention window closer. Background technique [0002] A fire-resistant window refers to a window that, together with the frame, can meet the requirements of fire-resistant stability and fire-resistant integrity within a certain period of time. Fire windows should be used when lighting and ventilation are required on the outer walls of two buildings with insufficient fire separation distance, or between spaces separated by firewalls. Part of the fireproof window lies in its glass and frame, and part of its performance lies in the window closer. Since the window needs to be opened, in the event of a fire after opening, the window closer must be automatically closed to ensure the fire prevention effect. The existing window closers are generally electric, which have the problems of bulky structure, inconvenient installation, and affect the appea...
