Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy window technology, specifically to a novel screen window frame. Background Technology

[0002] With rapid modern economic development, people's demands for quality of life are increasing. In the home decoration industry, aluminum alloy doors and windows have gradually become a market trend. Regarding aluminum alloy window products, and considering market demand, some high-end residential projects require ultra-high mesh windows, such as... Figure 1 As shown, for larger window screens, the central section tapers, resulting in an unsightly overall appearance and even causing the screen mesh to loosen. For windows with a screen size exceeding 1000mm, the tautness of the steel (screen) mesh determines user acceptance; window screens with loose steel (screen) mesh will have less market appeal. Figure 2 As shown, in current practices, a middle waist 3 is usually added in the middle of the screen window frame to ensure the screen window tightens, but the setting of the middle waist 3 will affect the aesthetics. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a solution.

[0004] The objective of this utility model is achieved through the following technical solution: A novel screen window frame, comprising a horizontal frame and a vertical frame, which are assembled together, with the vertical frame being an arched section protruding in the middle.

[0005] Preferably, the vertical frame includes transition bars at both ends and an arched section in the middle.

[0006] The arc-shaped section on the vertical frame protrudes outwards, and the transition bar is perpendicular to the horizontal frame.

[0007] The bow-shaped segment is a rolled bow-shaped segment.

[0008] The beneficial effects of this utility model are: The screen frame provided by this utility model is suitable for window sashes with a size of 1000mm or more. It can tighten the steel (screen) mesh of the window sash more tightly, eliminating the need to cut the steel (screen) mesh at the waist of the sash, resulting in a more aesthetically pleasing product.

[0010] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0011] See Figure 3-5 This utility model provides a technical solution: A novel screen window frame, comprising a horizontal frame 21 and a vertical frame 22, is assembled from the horizontal frame 21 and the vertical frame 22. The vertical frame 22 includes transition rails 23 at both ends and an arched section 24 in the middle. The arched section 24 on the vertical frame 22 protrudes outward, and the transition rails 23 are perpendicular to the horizontal frame 21. In use, the screen mesh 1 is simply inserted into the screen frame 2.

[0012] Instructions for use Material cutting and pre-processing: First, the mesh fan profile is cut to the required dimensions. For extra-long materials exceeding 1000mm in length, a side roll bend is performed immediately after cutting. Specifically, at the starting point of the roll bend, 400mm from the end of the profile, pressure is applied to the side using mechanical equipment to create a slight arc bend in the profile. This step aims to introduce pre-tension in preparation for subsequent mesh stretching.

[0013] Assembly and temporary fixing: Assemble the pre-processed profiles into the frame of the screen. After the frame is assembled, use F-clamps (F-clamps) for temporary fixation and adjustment: At the starting point of the roll bend, an F-clamp is used for outward support, applying an outward force to prevent the frame from shrinking inward. As a preferred embodiment, the F-clamp is used for outward support at a distance of 400mm from the end.

[0014] At the highest point of the roll bend (i.e. the apex of the bend), tighten the F-clamp inward to apply an inward force to counteract the deformation caused by the bend.

[0015] This two-way adjustment ensures that the edge of the gauze fan remains in a straight line before the netting is stretched, avoiding the "waist-cinching" phenomenon.

[0016] Netting and tension release: While keeping the frame of the mesh screen straight, tighten and secure mesh 1. After tightening, release all F-clamps. At this point, due to the pre-tension generated by the side roll bending process, the profile will naturally spring back and deform slightly in the opposite direction, further tightening the mesh and achieving a straightening effect. The entire process utilizes the elastic properties of the profile and requires no additional tools or complex operations.

[0017] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
