Hidden type fireproof window

Abstract

The invention relates to a hidden type fireproof window. The hidden type fireproof window comprises a window frame and an openable window sash and further comprises door closers for controlling the window sash to be automatically closed when a fire disaster occurs, the door closers comprise a driving door closer and a driven door closer, a window shaft is arranged on the driven door closer, the window sash rotates around the window shaft to be opened and closed, a window sash groove is formed in the outer wall of the window sash, a window frame groove is formed in the inner wall of the windowframe, a concave cavity is defined by the window sash groove and the window frame groove when the window is closed, and the door closer is hidden in the concave cavity; the driving door closer comprises a shell, a swing cross rod rotationally connected to the shell, a hydraulic press connected into the shell and driving the swing cross rod to rotate and a cross rod sliding block connected to the end, away from the hydraulic press, of the swing cross rod, a limiting sliding groove matched with the cross rod sliding block is formed in the fireproof window, and the cross rod sliding block is connected into the limiting sliding groove in a sliding mode. The fireproof window has the effects of hiding the door closer, improving the aesthetic degree of the fireproof window and protecting the doorcloser.

Description

technical field [0001] The invention relates to the technical field of fireproof windows, in particular to a hidden fireproof window. 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. There are two types of fire windows sold in China: one is the fire window that not only maintains integrity within a specified time, but also has a heat insulation function; the other type maintains integrity within a specified time, but does not have insulation Thermally functional fire windows. From the fixed method, fire windows can be divided into: fixed fire windows and movable fire windows. Movable fireproof windows refer to fire...

AI Technical Summary

Problems solved by technology

Most of the existing door closers are external. If it is installed on a fireproof window, the installation box will protrude from the window sash, which will affect the aesthetics of the window.

[0004] The existing Chinese patent CN203160962U discloses a temperature-controlled release device for a fire-proof window, which breaks the positioning by melting and blasting the temperature-sensing element in the fuse, and realizes the automatic closing of the fire-proof window sash through the closing force of the door closer, but the above-mentioned patent application documents The middle door closer is an external type. When the window sash is closed, the aesthetics will be affected. In daily life, it is also not conducive to the protection of the door closer.

[0005] The above-mentioned existing technical solutions have the following defects: the door closer is placed outside the fireproof window, which makes the overall aesthetics of the fireproof window poor, and is also not conducive to the protection of the door closer, affecting the stability of the door closer
