A subframe with adjustable width

Abstract

The invention discloses a width-adjustable auxiliary frame. A plurality of frames are connected to form a sealed rectangular frame through corner connectors. Each frame comprises a first component, a second component, at least one third component and a fourth component from an outdoor side to an indoor side in sequence. The first component, the second component, the third component and the fourth component are connected with each other. A first clamping buckle connected with an adjacent third component is arranged on one side of the third component. A second clamping buckle connected with the adjacent third component or the fourth component is arranged on the other side of the third component. The width-adjustable auxiliary frame is convenient to mount and ingenious in design, the width of the auxiliary frame can be adjusted according to the width of the section of a mounting door frame, the problems caused by the fact that the door window section width is not matched with the auxiliary frame width are solved, sectional material waste is avoided, great water blocking and heat preservation effects are achieved, and great practicability is achieved.

Description

technical field [0001] The invention relates to a window subframe, in particular to an adjustable width subframe. Background technique [0002] With the improvement of people's quality of life, the requirements for housing are getting higher and higher, and relatively high-end doors and windows generally use sub-frames, so that people can easily replace the original doors and windows according to their preferences without It will cause damage to the wall itself, and the current sub-frames are all fixed in size, and their width cannot be adjusted accordingly with the change of the section width of doors and windows, which will cause inconvenience in actual installation and application. Changing the section thickness of doors and windows according to the requirements of use will cause a mismatch between the section width of doors and windows and the width of the sub-frame, resulting in waste of profiles and increased workload, and because the sub-frame is usually made of alumi...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an adjustable width sub-frame whose width can be adjusted accordingly with the change of the section width of the door and window, so as to solve the problem caused by the difference between the section width of the door and window and the width of the sub-frame. The problem caused by matching avoids the waste of profiles, adopts a heat-breaking bridge, and has a first baffle, which can achieve heat insulation and prevent rainwater leakage
