Description

Technical Field

[0001] The utility model relates to the technical field of screen window screens, in particular to a windproof sheet with a double-limiting structure. Background Art

[0002] Invisible screen window is a screen window with a screen that can be automatically rolled back. It is mainly used for ventilation and mosquito prevention. The frame is tightly attached to the window frame. When it is used, the screen is pulled down. When it is not used, the screen will automatically roll back into the screen box, which does not take up space and has strong sealing performance. It is coordinated with high-end home decoration. The existing invisible screen window is generally connected with a pull beam at the bottom of the screen, and the upper end of the screen is connected and fixed to the reel in the screen box. The screen is unfolded by pulling down and rolled up by the rotating elastic mechanism of the reel; the two sides of the screen are provided with longitudinal guide rails, and the sides of the screen slide up and down in the rails;

[0003] However, when the existing roller screen windows and screen doors are used in the southern coastal areas, they may encounter typhoons and other weather conditions. Due to excessive wind, the screen windows may be blown away. The reason is that general windproof sheets may be relatively simple single-piece plastic sheets, which are not firmly connected to the profiles and slide rails. During repeated use, especially when the wind reaches a certain intensity, the windproof ability is greatly weakened. The structural strength of the windproof sheet is insufficient and it is easy to deform, causing the windproof sheet and the screen to derail, thereby affecting the use function. In order to solve the above problem, a double-limit structure windproof sheet is proposed. Utility Model Content

[0004] According to the above existing technical problems, the utility model provides a double-limiting structure windproof sheet, which is characterized by comprising a limiting part, a sliding part, a yarn pressing positioning part, and a yarn pressing part, wherein the end of the limiting part is fixedly connected to the sliding part, the sliding part is fixedly connected to the yarn pressing positioning part, and the yarn pressing positioning part is fixedly connected to the yarn pressing part;

[0005] Further, the limiting part is fork-shaped, the middle part of the limiting part is connected to the sliding part, the yarn pressing positioning part is convex-shaped, the sliding part is connected to the middle part of the yarn pressing positioning part, and the lower part of the other end of the yarn pressing positioning part is connected to the yarn pressing part;

[0006] Furthermore, the entire windproof sheet is made of plastic or rubber.

[0007] Beneficial effects of the utility model:

[0008] The utility model inserts the limiting part into the slide rail, installs the slide rail in the profile, places the sliding part on the slide rail, places the gauze on the gauze pressing part and abuts against the upper half of the gauze pressing positioning part, sews the gauze and the gauze pressing part together by a sewing machine, installs windproof sheets on both sides of the gauze, installs the limiting part of the windproof sheet into the slide rail, and then fixes it with the profile to complete the installation, which can prevent the windproof sheet and the gauze from coming off the slide rail during repeated use and when the wind force is too strong, resulting in damage to the screen window;

[0009] Limiting part: adopts fork-type opening structure, which reduces weight and increases strength, effectively preventing the windproof sheet from falling out of the slide rail. Especially when dealing with typhoons that are prone to occur in the south, it can effectively prevent the windproof sheet and the gauze from falling out of the slide rail due to excessive typhoon winds;

[0010] Sliding part: The adjustment space reserved by the sliding part can meet the need for activity space when the screen window is pushed and pulled, so as to meet the adjustment needs of larger size screen windows;

[0011] Yarn pressing positioning part: it can make the operation of yarn pressing easier, and there is a better positioning point, which is convenient for positioning and installation of yarn net, and prevents the yarn net from being skewed or not straight during sewing;

[0012] The total length of the three parts of the limit part, the sliding part and the yarn pressing and positioning part is 6mm. The double convex points formed on the limit part and the yarn pressing and positioning part are used for positioning, so that the yarn winding has better balance, more uniform force and better smoothness when winding.

[0013] Through the space between the sliding part and the yarn pressing and positioning part, when the yarn mesh is sewn on the yarn pressing part, there is a certain space distance between it and the screen window profile and the slide rail, which can effectively prevent the yarn mesh from contacting and rubbing with the slide rail during use, thereby causing the phenomenon of yarn falling off, that is, the yarn mesh is separated by the yarn pressing and positioning part, completely avoiding friction and damage between the profile and the slide rail;

[0014] The limit part adopts a fork-shaped opening structure, which improves the balance and stability of the windproof sheet, increases the strength, and is convenient for winding yarn, reduces the tension of the coil spring when winding yarn, thereby increasing the service life of the screen window and improving the use effect;

[0015] The yarn pressing and positioning part adopts an asymmetrical design, that is, one side is thick and the other side is thin. When in use, the yarn net can be fixed on the thick side, which can prevent some thicker yarn nets from being higher than the protrusions of the yarn pressing and positioning part, and then rubbing against the slide rail or profile, causing yarn stripping. In addition, this design can also make the force more balanced when winding the yarn, the yarn net is closer to the center, and the screen window is smoother when winding back;

[0016] Compared with ordinary single-piece plastic windshields, the double-limit structure windshields have been improved in structural strength, stability, connectivity, etc. The integrated structure can effectively prevent the deformation and falling of the windshields caused by strong winds, thereby increasing the service life of the screen.
