Description
Technical Field
The utility model relates to an anti-drop device for window and possess its window.
Background
Windows have been widely used in various buildings in our lives, and windows used in living houses are almost always openable, and windows in some high-rise buildings are gradually enlarged. These windows are required to be highly safe and can have a significant impact if the window is dropped.
In general, a window mainly includes a window frame installed on an opening of a wall body, and a window sash openably and closably installed on the window frame, and the window sash mainly includes a window sash frame and a panel (the panel is mostly glass).
In order to prevent the window sash from falling off the window frame, a device for preventing the window sash from falling off is disclosed in chinese utility model application No. 200720172584.6. Specifically, as shown in fig. 1, the device for preventing the window sash from falling off includes fixing blocks 52 and 54 and a metal cord 53, the fixing blocks 52 and 54 are respectively fixed to the window frame 1 and the window sash 2, and the metal cord 53 is connected between the fixing blocks 52 and 54, so that when the window sash 2 itself falls off from the window frame 1, the window sash 2 that falls off can be pulled by the device.
However, for some large window sashes, the panels are made of glass, and the weight of the panels is quite large. At the moment that the window sash falls to be hung by the metal rope of the anti-falling device, the force applied to the metal rope is large, so that the metal rope is likely to break, and the anti-falling function is lost.
As a method for solving the above problem, generally, a metal cord is thickened or a plurality of drop-off prevention means are provided. However, the window sash needs to be opened when in use, the thick metal rope obviously makes the opening and closing operation of the window become heavy, and the plurality of anti-falling devices also affect the appearance.
In addition, when the window sash is in an open state, the connection distance of the metal rope may be increased due to the absence of the limiting device, which may cause certain influence.
Furthermore, when the window sash is closed, the metal cord is not provided with an auxiliary device, so that the storage of the metal cord has a certain influence on the operation of closing the window sash, and the window sash cannot be smoothly closed.
