Abstract

This utility model relates to the field of doors and windows, and more particularly to a grooved screen sash. The screen sash includes a profile frame and a screen installed within the profile frame. The edges of the screen are pressed and fixed to the window surface of the profile frame. A groove for pressing the screen is formed along the length of the profile frame on the window surface. Correspondingly, the screen sash has strip-shaped pressing members along the length of the profile frame to press and fix the edges of the screen within the pressing groove. Because the edges of the screen are pressed and fixed within the pressing groove of the profile frame by the strip-shaped pressing members, the pressure area of ​​the area pressed by the strip-shaped pressing members is large, the pressure is low, and the fine filaments of the screen are not easily broken.

Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a grooved screen door. Background Technology

[0002] A window screen consists of a window frame fixed to the wall and a screen panel movably mounted on the frame. The screen panel comprises a frame movably mounted to the window frame and a mesh screen fixed within that frame. The mesh screen is woven from fine wires, preferably made of stainless steel, which is strong, corrosion-resistant, and has a long service life. The stainless steel mesh screen is secured to the window frame using multiple screws, pressing its edges firmly against the frame. To improve the light transmittance of the stainless steel mesh, thinner wire diameter stainless steel mesh has appeared on the market, with its edges also secured to the screen panel using multiple screws. This type of mesh has thinner wires, and the area where the screws press against the edges is small, resulting in high pressure and making the stainless steel wires at the pressure points prone to breakage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a grooved mesh fan in which the edge of the mesh is pressed and fixed to the profile frame, and the fine mesh filaments are not easy to break.

[0004] To solve the above problems, this utility model provides a grooved screen fan, including a profile frame and a screen installed in the profile frame. The edge of the screen is pressed and fixed to the window surface of the profile frame. The window surface of the profile frame has a screen pressing groove along the length of the profile frame. The screen fan is provided with a strip-shaped pressing member along the length of the profile frame to press and fix the edge of the screen in the screen pressing groove. Furthermore, the strip-shaped clamping component specifically clamps and fixes the edge of the mesh to the side wall of the mesh pressing groove. Further still, the side wall of the mesh pressing groove is provided with a buckle, and the side wall of the strip-shaped clamping component is correspondingly provided with a locking element. The buckle and the locking element interlock with each other across the edge of the mesh, thereby clamping and fixing the edge of the mesh.

[0005] Furthermore, there are two buckles: a proximal buckle located on the side wall of the mesh pressing groove near the window and a distal buckle located on the side wall of the mesh pressing groove away from the window; correspondingly, there are two locking pieces: a proximal locking piece corresponding to the proximal buckle and a distal locking piece corresponding to the distal buckle, with the distal locking piece being smaller than the proximal locking piece.

[0006] Furthermore, the top of the strip-shaped clamping member extends radially outward with a stop portion that blocks the portion of the mesh located on both sides of the mesh pressing groove opening to prevent bulging in that portion.

[0007] Furthermore, the strip clamping element is made of an elastic material.

[0008] Furthermore, the strip-shaped clamping component is specifically a rubber strip.

[0009] Furthermore, the cross-section of the strip clamping element is U-shaped.

[0010] Beneficial effects: The edges of the mesh are pressed and fixed in the mesh pressing groove of the profile frame by the strip clamping parts. The area of ​​the pressure area pressed by the strip clamping parts is large, the pressure is small, and the fine mesh filaments are not easy to break. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] gauze fan Figure 1 As shown, the device includes a profile frame 1 formed by four profile edges and a stainless steel mesh 3 installed within the profile frame 1. The window surface 5 of the profile frame 1 has a mesh-pressing groove 4, which forms a four-sided frame along the length of the profile frame 1. The mesh sash is equipped with four adhesive strips 2 (only the adhesive strip 2 located on the right side of the window surface 5 of the profile frame 1 is shown in the figure), corresponding to the four sides of the mesh-pressing groove 4. The four edges of the stainless steel mesh 3 are pressed and fixed within the mesh-pressing groove 4 by these four adhesive strips 2. The pressure area is large, and the pressure is small, so the fine wires of the stainless steel mesh 3 in the pressure area are not easily broken. The adhesive strips 2 are made of PVC and will not cause galvanic corrosion with the stainless steel mesh 3.

[0018] When making a gauze fan, see Figure 2The operator first places the profile frame 1 horizontally on the workbench of the pressing equipment (not shown in the attached diagram), then lays the stainless steel mesh 3 horizontally on the window surface 5 of the profile frame 1, and cuts off the four corners of the stainless steel mesh 3. A pad 10, with a height equal to that of the profile frame 1, is fixed to the workbench at the window of the profile frame 1. A horizontal pressing cylinder 11, facing backward, radially clamps and fixes the front edge of the profile frame 1 together with the pad 10. A downward pressing cylinder 12, facing downward, axially clamps and fixes the stainless steel mesh 3 together with the pad 10. The operator can then perform edge fixing treatment on the stainless steel mesh 3: using a mesh shaping pressing roller 13 (the width of the mesh shaping pressing roller 13 is smaller than the width of the pressing groove 4), the operator presses the front edge of the stainless steel mesh 3 into the pressing groove 4 and rolls it back and forth along the front edge of the pressing groove 4 to shape it. After shaping, take the corresponding adhesive strip 2 from the front of the mesh pressing groove 4 and place it on the front of the mesh pressing groove 4. Use a rubber mallet to tap the beginning of the adhesive strip 2 into the mesh pressing groove 4. Then, use an adhesive strip pressing roller (not shown in the attached diagram, the roller width is larger than the groove width of the mesh pressing groove 4) to roll from the beginning to the end of the adhesive strip 2 until the adhesive strip 2 is completely pressed into the front of the mesh pressing groove 4. The adhesive strip 2 then acts as a strip-shaped clamping element, pressing and fixing the front edge of the stainless steel mesh 3 into the front of the mesh pressing groove 4. The other three adhesive strips 2 are used in the same way to press and fix the other three edges of the stainless steel mesh 3 into the mesh pressing groove 4, and the mesh fan is completed.

[0019] See Figure 3 The mesh pressing groove 4 has a near-side buckle 41 on the side wall near the window and a far-side buckle 42 on the side wall away from the window. The outer wall of the adhesive strip 2 has a near-side clip 61 corresponding to the near-side buckle 41 and a far-side clip 62 corresponding to the far-side buckle 42. The adhesive strip 2 is pressed into the mesh pressing groove 4. The near-side buckle 41 and the near-side clip 61 are locked together through the edge of the stainless steel mesh 3, and the far-side buckle 42 and the far-side clip 62 are locked together through the edge of the stainless steel mesh 3. In this way, the edge of the stainless steel mesh 3 is clamped and fixed.

[0020] See adhesive strip 2 Figure 4 Its cross-section is U-shaped, with a stop 7 extending radially outward at the top to block the stainless steel mesh 3 located on both sides of the groove opening of the mesh pressing groove 4 to prevent bulging in that area. Because the distal clamp 62 is smaller than the proximal clamp 61, the clamping force between the adhesive strip 2 and the distal buckle 42 is weaker, making it easy to disassemble and replace.

[0021] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
