Method for making a device to prevent window sash from falling off
Technical field:
This utility model relates to casement windows, mainly a device for casement windows Device to prevent window sashes from falling off.
Background technology:
It is known that a casement window is composed of a window frame and a window sash. The window sash is connected to the window frame through a folding, hinge or connecting rod structure. If the window sash is not installed, it will fall off due to rust or looseness of the connecting parts, which is not safe and can easily cause injury to people at high altitudes.
The traditional method is to connect a chain or thin steel wire rope between the window frame and the window sash, and fix both ends of the chain or thin steel wire rope to the window frame and window sash respectively. When the window sash slips, the chain or thin steel wire rope will The wire rope can hold the window sash for safety. However, this connection structure directly exposes the chain or thin steel wire rope to the outside, which has the disadvantages of being unsightly, preventing the window sash from opening, and being easy to rust and break. Summary of the invention
The purpose of this utility model is to provide a device to prevent the window sash from falling off. The device is built-in. When the window sash is closed, the thin steel wire rope connecting the window frame and the window sash enters the casing, and the entire device It is hidden between the window frame and the frame of the window sash and cannot be seen. When the window sash is opened, the thin steel wire rope is pulled out from the casing as the window sash and moves freely, thus overcoming the shortcomings of the chain or thin steel wire rope of the existing casement windows. .
The device structure for realizing the present utility model is that this device is used to connect between the window sash and the window frame, and includes a sash fixed block, a window frame fixed block, an elastic metal wire, and a sleeve, wherein the elastic metal wire The sash fixing block and the window frame fixing block are connected together. The sash fixing block is provided with a through hole, and a sleeve is inserted into the through hole. One end of the elastic metal wire is fixed with the window frame fixing block, and the sash fixing block is fixed with the window frame fixing block. The other end passes through the through hole of the window sash fixing block and enters the sleeve. A limit block is fixed at the end of the elastic wire passing through the through hole. The diameter of the limit block is larger than the diameter of the through hole.
The structure of the device also includes that the connection between the window sash and the window frame means that the window sash fixing block is fixed on the window sash, and the window frame fixing block is fixed on the window frame.
The window sash fixing block is provided with a through hole, a sleeve is inserted into the through hole, and the other end of the sleeve is fixed on the window sash.
The sash fixed block is provided with a through hole, the upper end of the through hole is provided with an enlarged hole, the aperture of the enlarged hole is larger than the aperture of the through hole, and the sleeve is inserted into the enlarged hole. .
The elastic metal wire includes thin steel wire rope or steel wire.
The utility model has the beneficial effects of good safety, simple structure, low cost, and convenient installation and use.
