Embodiment Construction

[0022] Such as figure 1 As shown, an automatic closing device for a fireproof window includes a driving device 1 and a supporting device 2, and the driving device 1 and the supporting device 2 are respectively arranged between the sash 3 and the window frame 4 of the fireproof window, The drive device 1 is used to automatically turn or retract the window sash 3 into the window frame 4, and the support device 2 is used to support the open state of the window sash 3 and prevent the window sash 3 from being pushed by external force or by the drive device. 1 automatically rotates or retracts to close into the window frame 4; the support end of the support device 2 is made of a heat-sensitive element, so that the support end of the support device 2 does not move at a temperature below 60°C, and The supporting end of the supporting device will melt within 60s-120s when the temperature is above 70°C, causing the supporting device 2 to lose its supporting force, so that the sash 3 wil...

Abstract

The invention discloses an automatic closing device for a fireproof window. The automatic closing device comprises a driving device and a supporting device, wherein the driving device and the supporting device are both arranged between a sash and a window frame, the driving device is used for making the sash automatically rotate or retract into the window frame in a closed mode, and the supporting device is used for supporting the open state of the sash and preventing the sash from automatically rotating or retracting into the window frame in a closed mode; the supporting end of the supporting device is made of a heat sensitive element so that the supporting end can not move at a temperature below 60 DEG C, the supporting end of the supporting device can be molten at a temperature above 70 DEG C within 60-120 s to make the supporting device lose supporting capacity, and then the sash automatically rotates or retracts into the window frame in a closed mode under the action force of the driving device. The automatic closing device is simple in structure, convenient to install, and capable of realizing multiple functions including supporting the open state of the sash and automatically closing the fireproof window at a temperature around 70 DEG C when a fire occurs.

Description

technical field [0001] The invention relates to the technical field of fireproof windows, in particular to an automatic closing device for fireproof windows. Background technique [0002] The current fire-proof windows need a thermostat and a door closer to automatically close the fire-proof windows when a fire breaks out. The aesthetics of the fireproof window is greatly reduced, and the vulnerability is high, so there is a hidden danger of being demolished by others. Contents of the invention [0003] The purpose of this invention is to provide an automatic closing device for fireproof windows, which has a simple structure, is easy to install, and has multiple functions. Automatically shuts off. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] An automatic closing device for a fireproof window, comprising a driving device and a supporting device, the driving device and...
