Technical Field

The utility model relates to the technical field of fireproof window accessories, in particular to a window closer capable of being controlled to be closed through temperature sensing.

Background

A window is architecturally defined as an opening made in a wall or roof to allow light or air to enter the room. With the development of technology, various types of windows have been derived, including fire windows, which are windows capable of isolating and preventing the spread of fire, and window closers are often installed on the fire windows.

Common window closer comprises the wind brace more, and the wind brace is fixed between fire prevention window and window frame, makes the casement open certain angle as required to prevent that the casement from swinging at will because of the wind pressure, but current wind brace is difficult to when the proruption conflagration self-closing window, prevent the circulation of air, control stretching of intensity of a fire, and traditional window closer's practicality remains to improve.

Therefore, a window closer capable of being closed through temperature-sensitive control is provided.

SUMMERY OF THE UTILITY MODEL
