Push-and-pull open-type door or window

Abstract

The invention relates to a push-and-pull open-type door or window, mainly solves the technical problems that the existing push doors or windows are difficult to be assembled and do not have inward-falling using function. The push-and-pull open-type door or window comprises a framework and a movable sash, the movable sash is assembled on the framework through an upper slide gear and a lower slide gear and can be pushed and pulled to open far from the framework plane; the upper slide gear comprises an upper sliding part and an upper swing arm; the lower slide gear utilizes a vehicle-type self-locking door and window mechanism and comprises a front pulley and a back pulley which are respectively hinged with the front ends of a front swing arm and a back swing arm; and the back ends of the upper swing arm, the front swing arm and the back swing arm are respectively hinged with the upper frame and the lower frame of the movable sash. The push-and-pull open-type door or window has the advantages of compact structure, strong integrity, fast assembly and labor saving when in use, and is difficult to deform. Moreover, the inward-falling function of the movable sash is reasonably realized to ensure that the push-and-pull open-type door or window can be opened for ventilation at original close position.

Description

technical field [0001] The invention belongs to the technical field of doors and windows in the construction industry, in particular to a push-pull door and window with an inward-turning function. Background technique [0002] The installed doors and windows of existing buildings are generally outward-opening or inward-opening doors and windows, namely casement doors and windows. This kind of door and window adopts the installation structure such as side shaft (such as hinge) and the opening method of rotating around the side shaft. There are structural defects such as door and window sashes drooping, easy to deform, and opening takes up a large space, and the integrity is relatively poor. Difference. [0003] Based on the above situation, various push-pull doors and windows have been launched on the market now. Generally be to install pulley on door, sash lower frame, slide to realize its push-pull function by pulley. Such doors and windows only unilaterally overcome the...

Problems solved by technology

[0005] The present invention mainly solves the technical problems that the existing various sliding doors and windows are laborious to open and close and are easily deformed, and the assembly and installation are difficult and the assembly is not in place; in addition, the existing sliding windows must be pushed and pulled away from the window sash The technical problem of ventilation and other functions can only be realized in the original closed position; and then provide a push-pull door or window with high safety performance, accurate and fast assembly, and the movable fan is always in the parallel frame plane when opening or closing and push-pull opening or push-pull closing And push-pull opening doors or windows with inversion function
