Description

Technical Field

[0001] The utility model relates to the technical field of screen window yarn winding rods, in particular to a yarn winding structure with the function of quickly pressing yarns to remove deflection. Background Art

[0002] Invisible screens are popular among consumers due to their aesthetics and the convenience of opening and closing. They have been widely used in major construction companies. Invisible screens are screens with automatically retracted screens, mainly used for ventilation and mosquito prevention. The frame is tightly attached to the window frame. When in use, the screen is pulled down, and when not in use, the screen will automatically retract into the screen box. The screen can effectively block foreign mosquitoes and debris when the window is open, and can be rolled up when the window is closed to prevent dust and damage, and to ensure the transparency of the window. At the same time, it does not take up space and has strong sealing, which is coordinated with high-end home decoration.

[0003] However, the existing invisible screens have defects in the design of the winding structure. In order to maintain the structural strength, the winding rods are often designed to be relatively large and thick, so that the screen boxes for placing various parts are often relatively wide, which affects the overall aesthetics of the invisible screen and the lighting effect of the window; the current traditional winding rods mostly use round hollow profiles. When the screen is large and the amount of winding is large, the winding rods often bend and deform, deflect too much, run unstable, and shake due to length, weight and other problems, which causes the two sides to be unbalanced when the gauze is rewound, the two sides to run unstable, and the gauze appears to be stripped; in addition, the winding rods and gauze of the popular invisible screens on the market at this stage mostly use a direct bonding connection method. Although this method is relatively low in cost, The production process is relatively complicated, with long working hours and many steps, and it is not easy to flatten. The gauze is prone to wrinkles. The most important thing is that it is easy to fall off after long-term use, causing damage to the screen and affecting its use. The winding rod with a penetration connection is also prone to gauze wrinkles and is not easy to flatten. In addition, the plastic connector inserted into the winding rod is prone to breakage, causing the gauze to fall off. In addition, the penetration connection often requires reserving connection slots on the winding rod, so that the winding rod is non-standard circular, further increasing the deflection problem when winding the yarn, and further increasing the force imbalance when the gauze is rewound, jamming and gauze delamination. In order to solve the above problems, a winding structure with a function of quickly pressing the yarn to remove the deflection is proposed. Utility Model Content

[0004] According to the above existing technical problems, the utility model provides a yarn winding structure with the function of quickly pressing the yarn to remove the deflection, which is characterized by comprising a yarn winding rod, a pressure cover is arranged above the yarn winding rod, a yarn pressing groove is arranged on the upper surface of the yarn winding rod, a connecting hole is arranged inside the yarn winding rod, an anti-slip groove is arranged on the surface of the yarn winding rod, a high-definition yarn net is arranged between the yarn winding rod and the pressure cover, a rotating eccentric shaft is arranged on the connecting hole, and a coupling sleeve is arranged on the rotating eccentric shaft;

[0005] Further, the yarn winding rod is an elongated cylindrical shape, the yarn pressing groove is fixedly arranged on the upper surface of the yarn winding rod, the yarn pressing groove is an elongated strip, the pressure cover is an elongated strip, the vertical cross section of the pressure cover is π-shaped, the cross section of the yarn pressing groove is a groove shape with protrusions on both sides of the top, the bottom protrusion of the π-shaped pressure cover is engaged with the groove of the yarn pressing groove, the connecting hole is located in the middle of the yarn winding rod and passes through the yarn winding rod, and the cross section of the connecting hole is a waist drum shape;

[0006] Furthermore, the anti-skid groove is located on the outer surface of the yarn winding rod, the anti-skid groove is arc-shaped, there are a plurality of anti-skid grooves, which are evenly distributed on the outer surface of the yarn winding rod, and the yarn pressing groove and the pressure cover on the yarn winding rod are engaged to clamp the high-definition yarn net;

[0007] Further, the shaft cross section of the rotating eccentric shaft is waist-drum-shaped, the middle part of the rotating eccentric shaft has an annular protrusion, one end of the rotating eccentric shaft extends into the connecting hole, one end of the rotating eccentric shaft and the coaxial shaft is connected to the coupling sleeve, the middle part of the coupling sleeve has a waist-drum-shaped opening, and the other end of the coupling sleeve is connected to the rotating shaft;

[0008] Furthermore, the yarn winding rod is formed by metal integration.

[0009] Beneficial effects of the utility model:

[0010] The utility model adopts a unique π-shaped yarn pressing structure, and the pressing cover and the yarn pressing groove are separate structures. When assembling, the high-definition yarn net is placed flat on the yarn pressing groove, and the pressing cover and the yarn net are directly pressed into the yarn pressing groove by tools such as hammers, so as to achieve the effect of rapid installation. At the same time, the high-definition yarn net can be quickly flattened without wrinkles by using the pressing cover, thereby realizing rapid yarn pressing. This design does not require a large amount of equipment, parts, tools, adhesives, etc., and basically only needs a hammer to complete the installation. While achieving rapid yarn pressing, the flatness of the yarn net and the firmness of the connection are guaranteed;

[0011] By improving the winding rod, the above-mentioned pressure cover and the yarn pressing groove are combined into a winding rod, and the winding rod is a reinforced structure, so the strength and force of the winding rod structure are greatly increased, and the occurrence of the winding rod breakage, aging deformation and the like is avoided. At the same time, the reliability and stability are increased, so that the problem of excessive deflection when winding the yarn is avoided, thereby ensuring the stability of the screen window when it is rolled back and the balance of the forces on both sides, avoiding the occurrence of jamming, yarn mesh delamination and the like;

[0012] In addition, by adding a number of anti-skid groove structures on the winding rod structure, it can effectively play an anti-skid and fixing role, and at the same time can increase the contact area of ​​the winding rod, increase the winding amount, and at the same time increase the strength of the winding rod, reduce the deflection during rotation, and improve the stability of the winding;

[0013] By improving the structure of the winding rod, the strength of the winding rod can be increased while the diameter and size of the winding rod can be greatly reduced, which can be nearly half the size of the ordinary winding rod currently on the market, thereby greatly reducing the size of the screen box equipped for this purpose, and realizing the invisible screen window design of the ultra-thin screen box, which not only improves the overall aesthetics of the screen window, but also reduces the obstruction of the window, greatly increasing the lighting area of ​​the screen window.
