[0002] At present, the application of screen window is very extensive. The most common screen window is composed of high-definition screen, screen window frame and screen window pressure strip. Before using the screen window, the high-definition screen needs to be installed on the screen window, and the screen window pressure strip and the high-definition screen are pressed into the screen window groove together to complete the installation. However, the common pressure strips are mostly sponge or rubber pressure strips. Such pressure strips are relatively cheap, but the sealing effect is not good. When subjected to force, the screen is easy to pop out from the pressure screen groove, causing the screen to fall off; in addition, the pressure strip generally requires tools such as a pressure wheel to be pressed into the screen window screen groove. The production is more cumbersome, and there are more processes. Professional workers are required to operate, which increases the cost of use and replacement; moreover, the screen is easy to wrinkle when the pressure strip is pressed, and pulling the net too tight will cause the screen to deform and the mesh to be uneven. Workers are prone to fatigue after long-term manual labor, which will inevitably cause problems such as loose pressure strips, excessive screen residues, and skewed screens, which directly lead to low installation quality and affect the use effect. In order to solve the above problems, an S-shaped pressure screen positioning mechanism with a flattening function is proposed. Utility Model Content

The yarn pressing groove 1 has a cavity 4, the left limiting portion 2 is arranged above the yarn pressing groove 1, the right limiting portion 3 is arranged above the yarn pressing groove 1, the S-shaped yarn pressing strip 5 is arranged on the cavity 4, and the gauze 12 is arranged between the yarn pressing groove 1 and the S-shaped yarn pressing strip 5;

[0017] Further, the S-shaped pressing yarn strip 5 is composed of a C-shaped portion 6, a right fixing portion 7, a left fixing portion 8, a positioning portion 9, a pressing yarn portion 10, and an adjusting portion 11. The positioning portion 9 is arranged outside the C-shaped portion 6, the C-shaped portion 6 and the positioning portion 9 are connected as a whole, the right fixing portion 7 is arranged below the C-shaped portion 6, the C-shaped portion 6 and the right fixing portion 7 are connected as a whole, the pressing yarn portion 10 is arranged below the right fixing portion 7, the right fixing portion 7 and the pressing yarn portion 10 are connected as a whole, the adjusting portion 11 is arranged above the pressing yarn portion 10, the left fixing portion 8 is arranged above the pressing yarn portion 10, and the left fixing portion 8 and the pressing yarn portion 10 are connected as a whole;

[0018] Further, the positioning portion 9 is located outside the yarn pressing groove 1, the positioning portion 9 is located above the right limiting portion 3, the C-shaped portion 6 is located on the left side of the right limiting portion 3, a gauze 12 is provided between the C-shaped portion 6 and the right limiting portion 3, the right fixing portion 7 is in contact with the gauze 12 and the inner wall of the cavity 4 in sequence, the yarn pressing portion 10 is spaced from the lower portion of the cavity 4, the left fixing portion 8 is in contact with the gauze 12 and the inner wall of the cavity 4 in sequence, and the left fixing portion 8 is located below the left limiting portion 2;

[0019] Furthermore, the right fixing portion 7 and the yarn pressing portion 10 form a triangular structure with the left fixing portion 8, the distance between the right fixing portion 7 and the left fixing portion 8 plus the thickness of the yarn mesh 12 on both sides is greater than the distance between the left limiting portion 2 and the right limiting portion 3, the adjusting portion 11 is located between the right fixing portion 7 and the left fixing portion 8, the adjusting portion 11 has convex columns, one of which is located on the rear side of the right fixing portion 7, and the other is located on the rear side of the left fixing portion 8, the two convex columns are symmetrically arranged, and there is a gap between the two convex columns.

[0020] Example 2

[0021] When in use, first place one side of the gauze 12 flat on the gauze pressing groove 1 of the profile notch, then place the gauze pressing portion 10 of the S-shaped gauze pressing strip 5 on the gauze 12, the S-shaped gauze pressing strip 5 is located above the gauze pressing groove 1, and then use a hammer or other tool to hammer the S-shaped gauze pressing strip 5 and the gauze 12 into the gauze pressing groove 1. At this time, a part of the gauze 12 is located in the gap between the gauze pressing portion 10 and the lower part of the cavity 4 of the gauze pressing groove 1. The gauze pressing portion 10 can press in more gauze 12 through its own length, thereby facilitating the flattening of the gauze 12. The space between the gauze pressing portion 10 and the bottom of the gauze pressing groove 1 can accommodate these extra gauze 12.

[0022] In the unstressed state, the right fixing part 7 of the S-shaped yarn pressing strip 5 and the inner wall of the cavity 4 hold the yarn mesh 12 against the right wall of the cavity 4, the left fixing part 8 and the cavity 4 and the left limiting part 2 hold the yarn mesh 12 at the junction of the left limiting part 2 and the cavity 4, and the C-shaped part 6 and the right limiting part 3 hold the yarn mesh 12. At this time, the yarn mesh 12 is fixed by the S-shaped yarn pressing strip 5 and the yarn pressing groove 1 at three points to form a stable fixing surface to ensure that the yarn mesh 12 will not fall out;

[0023] When the gauze 12 and the yarn pressing structure are stressed, the S-shaped yarn pressing strip 5 will move in a small range, and the S-shaped yarn pressing strip 5 will undergo a slight displacement. At this time, the positioning part 9 is pressed down, and the end of the positioning part 9 and the upper end of the yarn pressing groove 1 clamp the gauze 12, the upper end of the C-shaped part 6 and the upper end of the right limiting part 3 hold the gauze 12, and the left fixing part 8 and the cavity 4 and the left limiting part 2 hold the gauze 12 at the junction of the left limiting part 2 and the cavity 4. The gauze 12 is still fixed at three points by the S-shaped yarn pressing strip 5 and the yarn pressing groove 1 to prevent the S-shaped yarn pressing strip 5 and the gauze 12 from popping out of the mouth of the yarn pressing groove 1;

[0024] When the gauze 12 and the yarn pressing structure are under stress, the distance between the two protrusions can be adjusted through the adjustment part 11 between the right fixing part 7 and the left fixing part 8, so that the distance between the two ends of the yarn pressing strip can be adjusted. Firstly, it is convenient for pressing the yarn. When the hammer hits, the distance can be compressed by deformation so that the whole can enter the yarn pressing groove 1. Secondly, it is convenient to adapt to the needs of various yarn meshes 12 with different thicknesses. By adjusting the distance, it can prevent the yarn mesh 12 from being too thick and causing too tight contact with each contact point, thereby breaking the yarn mesh 12.
