Sealed sliding type casement window

Abstract

The invention discloses a sealing push-pull type side-hung window. The problems that an existing side-hung window is large in window opening radius and inconvenient to operate, parts are likely to be damaged, and the sealing effect needs to be improved are solved. According to the technical scheme, a window frame and a window sash are included, the end face of the window frame and the end face of the window sash are correspondingly connected through a sliding device, and the sliding device comprises a window frame slideway arranged on the window frame end face, a window sash slideway correspondingly arranged on the window sash end face, a window frame connecting rod and a window sash connecting rod; one end of the window frame connecting rod is hinged to one side of the window frame end face, and the other end of the window frame connecting rod is hinged to a sliding block inside the window sash slideway; one end of the window sash connecting rod is hinged to the other side of the window sash end face, and the other end of the window sash connecting rod is hinged to a sliding block inside the window frame slideway. The sealing push-pull type side-hung window is simple in structure, high in support strength, flexible in window opening and closing, small in window opening moving space, capable of achieving 180-degree full opening of the window sash, good in sealing effect, not likely to damage and long in service life.

Description

technical field [0001] The invention relates to a window structure, in particular to a casement window. Background technique [0002] The most common existing windows are casement windows and sliding windows, both of which have their own advantages and disadvantages: the window structure of a casement window is usually composed of a window frame and a sash, and one end of the sash is respectively connected to the upper part of the window frame through a connecting rod. The frame and the lower frame are hinged. This kind of casement window cannot achieve a full 180-degree open state. For high-rise inward-opening windows, there are insufficient support strength, excessive movement arc surface of the window, and occupying room space after the window is opened. The problem. In response to the above problems, there is also a method of connecting two connecting rods. The two ends of a short connecting rod are respectively hinged with one side of the window frame and sash, and the...

[0002] The most common existing windows are casement windows and sliding windows, both of which have their own advantages and disadvantages: the window structure of a casement window is usually composed of a window frame and a sash, and one end of the sash is respectively connected to the upper part of the window frame through a connecting rod. The frame and the lower frame are hinged. This kind of casement window cannot achieve a full 180-degree open state. For high-rise inward-opening windows, there are insufficient support strengths, excessively large motion arcs for opening windows, and occupying room space after opening. The problem

The above-mentioned structure can realize the full opening of the sash at 180°, and also improves the support strength to a certain extent, but there are still the following disadvantages: 1: The expansion radius of the sash is close to the length of the long connecting rod, and there is still a considerable arc of window movement, while Most of the window sashes of this type are inward opening windows, which still have the problem of occupying the space in the room.

2: Sealing problem: In order to achieve sealing, a gasket is usually added to the end face of the window frame, but on the one hand, this may cause excessive friction when opening the window and make it difficult to open. On the other hand, for windows with slideways As far as the end face of the frame is concerned, the gasket cannot be installed

And for the window sashes that require a large rotation to open, the angle change of the edge of the window sashes will cause the gasket on the window frame to be rubbed repeatedly, reducing the sealing effect

3: The supporting force needs to be further improved: when the window sash is opened, the long and short connecting rods are stressed unevenly, and the long connecting rod will be subjected to greater force. When used for a long time, it is prone to damage and reduces the service life.

However, when this kind of sliding window is in the closed state, there is an inevitable gap between the two sashes, the sealing and sound insulation effects are not good, and there is also the problem of inconvenient installation and maintenance when installed at high altitude.
