Description

Locking mechanism for automatically closing window in outdoor fire

Technical Field

The utility model relates to a fire-resistant window, fire prevention window's special parts, specifically speaking are outdoor meet automatic window locking mechanism that closes of fire.

Background

According to the provisions of the content of the national fire window GB16809-2008 standard 8.13.2, the fire window sash is required to be opened, when a fire test is carried out, if the fire window sash is reliably and automatically closed within 60s (including 60s) of the beginning of the fire test, the fire test is continuously carried out, otherwise, the fire test can be stopped.

The automatic window closing can be realized by products with the following two structures in the current market:

one product is that the reducing version of door closer is directly applied to the window, and its shortcoming is that when opening and closing the window, the window must be used for normal opening and closing with the damping force that is greater than the door closer, and women and children will receive certain use restriction. Secondly, the internal structure of the window closer generally contains grease, and the fire is large and easy to cause combustion or explosion; thirdly, the self-closing device in case of fire cannot meet the living needs of the window sashes opened at any angle in daily practical use, only can be opened to a set opening angle (only one angle), and the self-closing mechanism can only act when the window sashes are opened to the specific angle and in case of fire outside the window. Fourthly, the structure can not be applied to the window type with inward opening, inward reversing and outward opening and downward suspension, and has certain limitation.

Although the other product adopts a spring energy storage structure, the secondary combustion and explosion in fire are avoided, but the excitation device of the temperature sensor is limited to be arranged in the window frame, and the fire temperature cannot be transmitted to the excitation device of the temperature sensor in time, so that the window can be closed automatically in time when the fire outside the window is met, and the window can be closed untimely or fails to close.

In summary, the existing automatic locking structure for fire outside the window in the market has the following disadvantages: after the window is automatically closed, the self-existing locking structure of the window is not utilized, but a special latch structure is utilized, if the latch structure meets the tight and tight effect of the closed window, the timely window closing rate is not one hundred percent, which is caused by structural defects, if the window closing rate is one hundred percent, the compactness between a window frame and a window sash is sacrificed, and thus, smoke and fire can be caused to flow into a room from an unclosed gap.

When the window is closed in case of fire in the current market, the phenomena of untight closing and untight sealing generally exist after the window is closed in case of fire, and the defects that smoke and fire still enter the room through a gap which is not tight enough still exist, so that the defects are caused because products in the current market do not have a locking mechanism which can effectively utilize the window.
