High-wind-preventing self-closing center-pivoted window

Abstract

The invention discloses a high-wind-preventing self-closing center-pivoted window. The high-wind-preventing self-closing center-pivoted window comprises a window frame and a window body, wherein a notch is formed in the inner wall of one side of the window frame; the notch and the inner wall of the window frame are rotatably connected with a rotary shaft; the back part of the window body is fixedly connected with the rotary shaft; threads are arranged on the outer wall of the rotary shaft in the notch; and the threaded part of the rotary shaft is in threaded connection with a rolling ball nut.The high-wind-preventing self-closing center-pivoted window has the advantages that: a wind wheel is driven by strong wind, so that power is transmitted to an outer slide block through a disc-shapedcam, a groove, a rolling ball and a rod body; under action of a magnetic attraction mechanism, the outer slide block transmits power to an inner slide block, and air in a slide cavity is gradually charged into a telescopic bag body through a gas inlet channel; the telescopic bag body drives a lower connecting plate and the rolling ball nut fixedly connected to the lower connecting plate to linearly motion, so that the rotary shaft drives the window body to perform rotary window closing action, and therefore, a scene described in the background technology of gale weather is avoided, the indoorenvironment is protected, and property loss is avoided.

Description

technical field [0001] The invention relates to the technical field of hanging windows, in particular to a self-closing central hanging window for strong wind protection. Background technique [0002] Hung windows refer to windows that open along the horizontal axis. According to the position of the hinge and the rotating shaft, they are divided into top-hung windows, bottom-hung windows, and middle-hung windows. Among them, the centrally hung window: the horizontal shaft is installed in the middle of both sides of the window sash, which has the advantages of convenient opening and closing, labor saving and rainproof. Hanging windows are widely used especially in high-rise buildings. However, in the long-term use process, it has been found that in windy weather, because the hanging windows are not closed, strong winds blow into the room, blowing down indoor paper documents, and even causing air convection. The main reason is that it floats out of the room, leading to the po...

Hanging windows are widely used especially in high-rise buildings. However, in the long-term use process, it has been found that in windy weather, because the hanging windows are not closed, strong winds blow into the room, blowing down indoor paper documents, and even causing air convection. The main reason is that it floats out of the room, leading to the possibility of file loss; if it is still raining, the raindrops will splash into the room, causing water to enter the floor, or even damage the floor, resulting in economic losses
