Angle positioning temperature control closer for automatic closing of fireproof window

Abstract

The invention discloses an angle positioning temperature control closer for automatic closing of a fireproof window. The angle positioning temperature control closer comprises a main arm and a guide rail provided with a sliding groove, wherein a positioning mechanism and a sliding mechanism are arranged in the sliding groove; one end of the main arm is connected to a door closer body, and the other end of the main arm is connected with the sliding mechanism; the positioning mechanism comprises a positioning block, an adjusting block and a temperature control pin; the end, facing the sliding mechanism, of the positioning block is provided with a lock hook matched with the sliding mechanism, and the positioning block is further provided with an adjusting hole; the adjusting block is rotationally arranged in the adjusting hole through a pin shaft; the temperature control pin abuts against the upper end of the adjusting block, and a locking screw on the adjusting block is rotated to lock the positioning mechanism to the sliding groove of the guide rail; and the positioning mechanism can be matched with the sliding mechanism. When the environment temperature is abnormal, the temperaturecontrol pin automatically bursts, locking of the positioning mechanism and the guide rail is relieved, the sliding mechanism drives the positioning mechanism to slide at the same time, and accordingly automatic door closing is completed.

Description

technical field [0001] The invention relates to the technical field of doors and windows, and more particularly, to an angle-positioning temperature-controlled closer for automatic closing of fire windows. Background technique [0002] The fire department requires modern buildings to be equipped with fireproof doors and windows. In the event of a fire, they can prevent air circulation, control the fire and block the spread of the fire; most of the fireproof doors and windows installed in existing buildings are directly fixed with hinges or hinges , In the event of a fire emergency, it needs to be manually closed, which cannot ensure safety and practicability; therefore, it is urgent to install a closer on the fireproof doors and windows that can automatically close in the event of a fire emergency. [0003] Door and window closer is a kind of door and window accessories that should be used in movable doors and windows to locate doors and windows and automatically close doors...

Problems solved by technology

[0002] The fire department requires modern buildings to be equipped with fireproof doors and windows. Once a fire breaks out, it can prevent air circulation, control the fire and block the spread of fire; most fireproof doors and windows installed in existing buildings are directly fixed by hinges or hinges. , in an emergency situation of fire, it needs to be closed manually, which cannot guarantee safety and practicability; therefore, it is urgent to install a closer that can automatically close in case of fire emergency on fire doors and windows

[0003] Door and window closers are a kind of door and window accessories that should be used in movable doors and windows to position doors and windows and automatically close doors and windows in case of fire emergency; door and window closers on the existing market often use springs and other accessories to solve the problem of door and window positioning , its structure is unstable, and the positioning effect is not good; in the event of a fire, the response is not sensitive, and the automatic closing function is often not realized, causing immeasurable losses
