Combined type window frame

Abstract

The invention discloses a combined type window frame. The combined type window frame comprises a window frame body. A sliding track is arranged on the window frame body, and a window is arranged on the sliding track. The sliding track is formed by combining a plurality of sliding blocks, a rotating shaft is arranged on the sliding blocks, a connecting arm with a through-hole is arranged on the window frame body, and the rotating shaft rotates in the through-hole. A channel with the position changing along with the rotating of the rotating shaft is formed between the rotating shaft and the side wall of the through-hole. A groove is formed in the bottom of the rotating blocks, a vent hole is formed in the side face of the upper end of the groove, a first magnet is arrange in the groove, a spring is arranged at the upper end of the first magnet, a one-way valve for air inlet is arranged at the bottom of the groove, and an air channel is formed between the bottom of the groove and the connecting arm. The air channel is disconnected with the channel when the rotating blocks are attached to the window frame body, and the air channel communicates with the channel when the rotating blocks are separated from the window frame body. A second magnet matched with the first magnet is arranged at the bottom of the window. By adoption of the combined type window frame, automatically dumping of dust in the sliding track is achieved, and thus dust and impurities are prevented from accumulating in the sliding track of the window fame body.

Description

technical field [0001] The invention belongs to the technical field of alloy window frames, in particular to a combined window frame. Background technique [0002] The window frame is the transition layer between the wall and the window, which plays a role in fixing and preventing the surrounding walls from collapsing. There is a slide rail at the bottom of the window frame, and the window slides in the slide rail. Since the slide rail is isolated into multiple areas, it is difficult to remove the dust and impurities in the slide rail. In the long run, it is necessary to manually remove the impurities in the slide rail, otherwise the It will cause the window to not open and close smoothly. The existing window frame slide rails are all integrated, and the dust in the slide rails cannot be poured out by turning over. Contents of the invention [0003] The invention provides a combined window frame for the deficiencies of the prior art, and the structure can automatically d...

Problems solved by technology

There is a slide rail at the bottom of the window frame, and the window slides in the slide rail. Since the slide rail is isolated into multiple areas, it is difficult to remove the dust and impurities in the slide rail. In the long run, it is necessary to manually remove the impurities in the slide rail, otherwise the Can cause the window to open and close poorly

The existing window frame slide rails are all one-piece, and the dust in the slide rails cannot be poured out by flipping
