Description

A track-changing horizontal push-closed door and window

technical field

The invention relates to a rail-changing flat-push closed door and window.

Background technique

Most of the traditional doors and windows are hinged to realize the opening and closing of the doors and windows. The hinged way makes the doors and windows closed not tight enough, and the wind resistance is poor. The hinged way is easy to cause the doors and windows to fall off, especially the windows, which are very unsafe to use in high-rise buildings. , and the hinged doors and windows are more laborious to push and pull, and the installation is troublesome.

For this reason, in the authorized notification number CN 204186236 U, in the Chinese utility model titled "broken bridge heat-insulating aluminum alloy track window", a broken bridge heat-insulated aluminum alloy track window is disclosed, which includes a window frame and multiple A window, the window frame is provided with a guide rail assembly, the window is matched and installed on the guide rail assembly, the guide rail assembly includes a main rail and a plurality of auxiliary guide rails, and the plurality of auxiliary guide rails are connected to the main rail, And the central axes of the multiple auxiliary guide rails are on the same straight line, the window moves between the main guide rail and the auxiliary guide rail, and slides reciprocally on the main guide rail.

Another example, application publication number CN 105003169 A, in the Chinese invention patent application titled "A Door and Window Opening and Closing Structure", discloses a door and window opening and closing structure, including a first window frame, a window sill and a second window frame , the surface of the window sill is provided with a first U-shaped slide rail, the window sill includes a left table, a middle table and a right table, the middle table is located between the left table and the right table, and the surface of the middle table is provided with a second Two U-shaped slide rails, and the bottom of the first U-shaped slide rail communicates with the bottom of the second U-shaped slide rail, the inner cavity of the first window frame is inlaid with first glass, and the first window frame A first pulley and a second pulley are respectively provided on both sides of the bottom of the second window frame, the inner cavity of the second window frame is inlaid with a second glass, and a third pulley and a fourth pulley are respectively provided on both sides of the bottom of the second window frame .

The above-mentioned type of track-changing doors and windows mainly also has the following problems: 1. The pulley is installed in the chute, and the pulley turns in the arc-shaped chute. The wheel surface of the pulley is in surface contact with the bottom of the chute. During the process, the side of the pulley may also rub against the side wall of the chute, resulting in a relatively large walking resistance of the pulley. 2. The setting of the arc-shaped chute is not reasonable enough. After the window or door leaves change planes, they are easy to shake, have poor strong wind resistance, and poor sealing performance. 3. When used on high-altitude windows, its safety performance is poor, and children may open the windows at will and climb out from the windows.
