Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0026] refer to Figure 1-Figure 5 As shown, the present invention discloses a fireproof window closer, which includes a fixing frame 10, a telescopic arm 20 and a temperature-sensitive elastic component. One end of the telescopic arm 20 is axially connected with the fixed frame 10, and the other end of the telescopic arm 20 is a telescopic end. The temperature-sensing elastic component includes an elastic recovery element 32 , a temperature-sensing element 33 , a sliding rail 3630 and a sliding block 31 . The sliding block 31 is arranged in cooperation with the sliding rail 3630 and the sliding block 31 can move along the sliding rail 3630 . One end of the slider 31 is axially ...

Abstract

The invention discloses a fire-retardant window closing device. The fire-retardant window closing device comprises a fixing frame, a telescopic arm and a temperature sensing elastic assembly; one endof the telescopic arm is connected with the fixing frame in a shaft mode, and the other end of the telescopic arm is a telescopic end; the temperature sensing assembly comprises an elastic recovery element, a temperature sensing element, a sliding rail and a sliding block; one end of the sliding block is connected with the telescopic end in a shaft mode, and the elastic recovery element is arranged between the other end of the sliding block and the sliding rail; a limiting groove is formed in the sliding rail, a locking and buckling piece which is matched with the limiting groove is arranged on the sliding block, one end of the temperature sensing element is connected with the sliding block in an abutting mode, and the other end of the temperature sensing element is connected with the locking and buckling piece in an abutting mode to enable the locking and buckling piece to be connected with the limiting groove in a clamping mode; and when the temperature sensing element bursts, the locking and buckling element is separated from the limiting groove, and the elastic recovery element pulls the sliding block to move. According to the fire-retardant window closing device, automatic window closing can be realized during a fire disaster, the structure is exquisite, the size is small, and practicability and convenience are achieved.

Description

technical field [0001] The invention relates to the field of window closers, in particular to a fireproof window closer. Background technique [0002] In the prior art, there are mainly two types of window closers: one is an electric window closer, and the other is a movable window closer controlled by a mechanical principle. It is mainly used for various movable fire windows, and its main functions are reflected in two aspects: on the one hand, it can open and position the fire windows in a limited way to improve ventilation and lighting effects; on the other hand, when a fire occurs, It can automatically close the windows to prevent the circulation of air, thereby controlling the spread of fire. [0003] However, the window closers currently on the market have a main body cylinder, which has a large volume and takes up a lot of space; and, during installation, the window frame and the sash need to be slotted, the manufacturing cost is high, and the sash profiles are damag...
