Description

Technical Field

[0001] This utility model relates to the field of gauze curtain technology, and in particular to a gauze curtain winding structure based on a roll-up gauze curtain. Background Technology

[0002] Sheer curtains are usually made of transparent or semi-transparent gauze. The weave of sheer curtains is also diverse, including plain weave, twill weave, and jacquard, and they come in a variety of colors. They can be used alone as curtains or combined with curtains as sheer curtains.

[0003] Nowadays, most sheer curtains are controlled by pull cords. This control structure is subject to wear and tear during adjustment, and the pull cord may break after prolonged use. Furthermore, the pull cord can be damaged by children pulling and playing with it. In addition, the aesthetics of the window structure where the pull cord and sheer curtain are combined are not satisfactory.

[0004] Based on this, a curtain winding structure based on a roll-up curtain is proposed. Utility Model Content

[0005] The purpose of this utility model is to propose a curtain winding structure based on a roll-up curtain in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The gauze curtain based on the roller blind includes a window frame, an installation plate connected to the upper end of the window frame, a winding drum connected to the installation plate through a connector, a rotating roller rotatably connected inside the winding drum, a lifting bar connected to the rotating roller through the gauze curtain, and an adjustment mechanism for controlling the opening and closing degree of the gauze curtain connected to the installation plate.

[0008] The adjustment mechanism includes a screw end, one end of which is connected to a worm gear. A disc groove is provided on the mounting plate. One end of the rotating roller is connected to a coil spring through a groove shaft. A hollow worm wheel is connected to the outside of the coil spring.

[0009] Preferably, symmetrical rollers are rotatably connected to the take-up drum.

[0010] Preferably, a protective cover is connected to the lower end of the lifting bar.

[0011] Preferably, the lifting bar has a telescopic groove, and an abutment frame is slidably connected in the telescopic groove. The abutment frame is connected to a spring block through an abutment spring, and the spring block is connected to the lifting bar. The window frame has a sliding groove.

[0012] Preferably, the hollow worm gear and the worm cooperate with each other, the hollow worm gear is rotatably connected in the disc groove, and the two ends of the coil spring are respectively engaged with the groove shaft and the hollow worm gear.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application adopts a coil spring structure, which utilizes the interaction between the coil spring and the abutment frame to balance the force on the curtain structure. The opening and closing degree of the curtain can be controlled by rotating the worm gear, eliminating the need for adjustment by pull cord. The structure is symmetrical and aesthetically pleasing.

[0015] 2. This application adopts a symmetrical roller structure, which uses symmetrical rollers to limit the position of the gauze curtain, thereby protecting the gauze curtain structure, avoiding wear between structures, and also playing a guiding role to prevent the gauze curtain from folding, thus ensuring the flatness of the gauze curtain.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] The gauze curtain based on the roller blind includes a window frame 1, an installation plate 2 connected to the upper end of the window frame 1, a winding drum 5 connected to the installation plate 2 via a connector 4, a rotating roller 14 rotatably connected inside the winding drum 5, a lifting bar 6 connected to the rotating roller 14 via the gauze curtain, and an adjustment mechanism for controlling the opening and closing degree of the gauze curtain connected to the installation plate 2.

[0024] Specifically, such as Figure 3 As shown, a symmetrical roller 13 is rotatably connected to the winding drum 5. By setting the symmetrical roller 13, the winding of the gauze curtain is limited, which protects the gauze curtain and ensures the flatness of the gauze curtain.

[0025] Specifically, such as Figure 3 As shown, the lower end of the lifting bar 6 is connected to a protective cover 9. The protective cover 9 protects the structure of the abutting spring 19 and hides part of the structure, thus improving the overall aesthetics of the structure.

[0026] Specifically, such as Figure 3 As shown, the lifting bar 6 has a telescopic groove 17, and an abutment frame 18 is slidably connected in the telescopic groove 17. The abutment frame 18 is connected to a spring block 16 through an abutment spring 19. The spring block 16 is connected to the lifting bar 6. The window frame 1 has a sliding groove 3. The abutment spring 19 can push one side of the abutment frame 18 to abut against the sliding groove 3, thereby stabilizing the height position of the lifting bar 6.

[0027] Specifically, such as Figure 1 and Figure 3 As shown, the adjustment mechanism includes a screw end 7 with a cross-shaped screw hole, allowing the operator to adjust the structure using a screwdriver. One end of the screw end 7 is connected to a worm gear 11. A disc groove 8 is provided on the mounting plate 2. One end of the rotating roller 14 is connected to a coil spring 10 via a groove shaft 15. The coil spring 10 stabilizes the position of the hollow worm wheel 12. The hollow worm wheel 12 is connected to the outside of the coil spring 10. The hollow worm wheel 12 and the disc groove 8 fit together, thereby improving the structural stability when the hollow worm wheel 12 rotates.

[0028] Specifically, such as Figure 3 As shown, the hollow worm gear 12 and the worm 11 cooperate with each other. The hollow worm gear 12 is rotatably connected in the disc groove 8, and the two ends of the coil spring 10 are respectively snapped onto the groove shaft 15 and the hollow worm gear 12.

[0029] In summary, the curtain winding structure based on a roller blind provided in this embodiment allows for easy adjustment of the curtain's opening degree by simply rotating the screw end 7 with a screwdriver. This causes the worm gear 11 to rotate, which in turn drives the hollow worm wheel 12. When the hollow worm wheel 12 rotates, it can adjust the tension of the coil spring 10 connected to it. One end of the abutment frame 18 abuts against the slide groove 3. When the lifting bar 6 moves up and down, it needs to overcome the friction between the abutment frame 18 and the slide groove 3. When the adjusted coil spring 10's retraction force is balanced with the friction force and the weight of the lifting bar 6's connecting structure, the curtain structure remains unchanged, thus achieving the effect of adjusting the curtain's opening degree.

[0030] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
