A sliding window emergency opening system

Abstract

An emergency opening system for a sliding window provided by the present invention includes an emergency opening device and an opening master control device; the first rotating shaft in the emergency opening device is rotatably installed on a first base; The shaft and one end are connected with the movable fan of the sliding window; the first ratchet is fixedly connected with the first rotating shaft; the first elastic member is compressed so that the first pawl is engaged with the first ratchet; the second rotating shaft in the master control device can be opened It is rotatably installed on the second base; one end of the master control traction cable is connected with the second rotating shaft, and the other end is connected with the first pawl; when the second rotational shaft rotates, the master control traction cable is wound to make the first pawl Break away from the first ratchet; because of the gravity effect of the sliding fan in the movable window, the first traction cable drives the first rotating shaft to rotate and the movable fan is opened. In practical application, the opening master control device can be set at a position away from the emergency opening device, and the movable fan can be opened by remotely controlling the emergency opening device.

Description

technical field [0001] The invention relates to the technical field of sliding windows, in particular to an emergency opening system for sliding windows. Background technique [0002] Sliding window is a new type of window that can realize the opening of sash in the vertical direction, and it is gradually applied in the field of engineering construction. The sliding window mainly includes a movable fan, a window frame and an opening device. The traction cable in the opening device is connected with the movable fan, and the traction cable drives the movable fan to move up and down along the direction-changing guide of the window frame. The power part in the opening device is a drive motor, and the rotation of the drive motor drives the action of the traction cable to realize the opening and closing of the movable window. [0003] In the event of an emergency such as a fire in a building, it is necessary to open the vertical sliding window to discharge the fire smoke. In the...

AI Technical Summary

Problems solved by technology

In the event of an emergency such as a fire, it is generally accompanied by a power outage, so the drive motor in the vertical sliding window cannot work normally.

Although the sliding window has been equipped with a mechanical emergency opening device in the prior art, due to risk factors such as fire and high-temperature smoke, it is very dangerous for the operator to enter the fire scene to activate the emergency opening device.
