Door and window frame material structure

Abstract

The invention discloses a door and window frame material structure, which mainly comprises a first frame strip, a second frame strip and a third frame strip. Ends of the same sides of the first frame strip and the second frame strip are respectively connected with two ends of the third frame strip, and the first frame strip is longer than the second frame strip. Due to the structural arrangement, the door and window frame material structure has the advantages that an assembling process of a door and window frame material can be simplified, gaps generated during usage of the door and window frame material can be covered, external dust and mosquitoes can be stopped from entering an indoor environment via the gaps, and the like.

Description

technical field [0001] The invention relates to a door and window frame material structure, in particular to a door and window frame material structure that can be assembled on a door and window outer frame in various ways such as external hanging or built-in. Background technique [0002] Existing window (door) structure usually can be provided with a plurality of slidable window (door) leaves on the inner edge of its outer frame, and barrier (such as glass etc.) is installed in the described window (door) leaf. ), so that when the window (door) leaf is moved to open and close the window (door) door, it can provide a variety of different performances such as airtightness and ventilation; however, once the existing window (door) door is opened, the outdoor Dust and mosquitoes are easy to enter the room from the open space of the window (door) door; and in order to improve this problem, many window (door) door structures will add a gauze on it. , to prevent outdoor dust and ...

Problems solved by technology

[0007] However, no matter what kind of known assembly method is used, what is often faced is that the openings of many buildings are often skewed due to factors such as poor quality of cement construction and other factors, resulting in the subsequent installation of windows. (Door) Outer frame 2 and screen window frame 1 are also in a skewed shape, so when the movable frame material 12 of screen window frame 1 is pushed to slide to the other side 114 of door and window frame 1 and the screen net 13 is unfolded, it often occurs. The movable frame material 12 cannot completely fit on the other side 114 of the skewed door and window frame 1 and there is a gap. Or there is a gap in the lower section but the upper section does not fit and there is a light transmission, so that external dust and mosquitoes can enter the room through the aforementioned gap, and the screen window frame 1 loses its original function. affect the appearance of the product
