Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to a screen window structure. Background Art

[0002] Window screens are devices installed on windows for ventilation and to block mosquitoes. They consist of a frame and a screen stretched across it. Current window screen frames are typically constructed from four framed sections, with the screen mesh snapped onto the edges. This results in a complex manufacturing process, difficult assembly, and low production efficiency. Furthermore, the frames lack any elasticity, making it difficult to tighten the screen mesh and causing it to wrinkle easily. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an elastic screen window structure which has simple manufacturing process, high production efficiency and the function of automatically tightening the screen, so as to overcome the deficiencies in the prior art.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An elastic screen window structure includes a frame and a screen connected to the frame at four edges. The frame is formed by bending and connecting an elastic steel bar wrapped with a plastic layer. The edges of the screen are welded to the plastic layer on the surface of the frame.

[0006] In the above technical solution, the present invention wraps a plastic layer around an elastic steel bar, directly bends the elastic steel bar into a frame, and directly welds the edges of the gauze to the frame. This elastic gauze structure uses elastic steel bars as the frame material, making the final frame elastic and able to tighten the gauze. Furthermore, this elastic gauze structure has a simple manufacturing process and high production efficiency.

[0007] In a specific implementation manner of the present invention, the frame is a rectangular frame.

[0008] In a specific embodiment of the present invention, the seams of the frame are connected by welding.

[0009] In a preferred embodiment of the present invention, the cross section of the elastic steel strip is rectangular. Such a cross section of the elastic steel strip makes the surface of the plastic layer smooth and has more areas that can contact the gauze, which not only facilitates welding with the gauze but also helps to improve welding strength.

[0010] In a preferred embodiment of the present invention, the thickness of the plastic layer on the steel strip is 0.5-1 mm. This thickness ensures that the plastic layer on the elastic steel strip has sufficient strength to ensure a strong weld to the screen, while also providing sufficient support for the tension between the frame and the screen, making the screen durable.

[0011] It can be seen from the above detailed introduction that the elastic screen window structure of the present invention has the advantage of automatically tightening the screen, and the manufacturing process of the structure is simple and the production efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 Schematic diagram of the elastic screen structure of the present invention;

[0013] Figure 2 for Figure 1 Middle AA section view;

[0014] Figure 3 This is a schematic diagram of the structure of the frame before the mesh is welded. DETAILED DESCRIPTION

[0015] like Figure 1 and Figure 2 As shown, the elastic window screen structure of the present invention comprises a rectangular frame 100 and a screen 200. The frame 100 is formed by bending a flexible steel bar 101, which is then wrapped with a plastic layer 102. The seams of the frame 100 are welded. The screen 200 is made of plastic and its edges are bonded to the plastic layer 102 on the frame surface.

[0016] In this embodiment, the thickness of the plastic layer is 0.5-1 mm, preferably 0.6-0.8 mm.

[0017] The above is the elastic screen window structure of the utility model, and its manufacturing method is:

[0018] S101. Wrap the surface of the elastic steel bar with a plastic layer.

[0019] In this step, the plastic layer is applied to the surface of the elastic steel strip using the same process used to coat cable conductors with insulation. This process is a mature and automated process, so this step of coating the surface of the elastic steel strip with a plastic layer can also be automated.

[0020] S102 , according to the size of the screen window to be manufactured, the elastic steel strip wrapped with the plastic layer is cut into predetermined lengths and bent into a quadrilateral frame, and the seams 103 of the frame are welded.

[0021] Since the steel bar is elastic, pay attention to the direction of the elastic force of the elastic steel bar when bending it, so that the four frame edges 110 of the frame 100 formed after bending are all in an outward convex arc shape under the elastic force of the elastic steel bar itself, as shown in the following example. Figure 3 shown.

[0022] S103, connecting the edges of the plastic mesh cut into a rectangular shape to the plastic layers on the four frame side surfaces by gluing. After gluing, the frame becomes rectangular under the constraint of the mesh.

[0023] During the production process of the present invention, special attention should be paid to the specific matching of elastic steel strips of different thicknesses and elastic forces for screens of different sizes, so that the four edges of the frame formed after bending naturally form an appropriate outward convex curvature. This appropriate curvature ensures that the frame, after being bonded to the screen, forms a rectangular shape under the restraint of the screen. The rectangular frame, in turn, tightens the screen without causing damage. The matching of the elastic steel strips can be verified through multiple trials.

[0024] In this step, the bonding method preferably adopts hot melt welding, which has the advantage of high welding efficiency. Of course, other welding methods can also be adopted, for example, ultrasonic welding can also be adopted.

[0025] The specific hot melt welding method is: place the quadrilateral frame that completes step S102 in a constrained mold, first constrain the frame to a rectangle in the mold, then lay the gauze on the frame so that the edges of the gauze are placed on the four frame sides of the frame, and finally use a hot ironing device to heat press the edges of the gauze so that the edges of the gauze are finally hot-ironized and bonded to the plastic layer on the surface of the four frame frames.
