[0036] like Figure 1 , 2 As shown, the utility model provides an installation device for a bead curtain, comprising: a top beam 1, provided with a first end 1.1 and a second end 1.2 opposite to each other; a reel 2, located below the top beam 1, provided with a third end 2.1 and a fourth end 2.2 corresponding to the first end 1.1 and the second end 1.2 respectively; a transmission part 3, connecting the second end 1.2 and the fourth end 2.2; a connecting part 4, connecting the first end 1.1 and the third end 2.1; a bead module 5, arranged in the top beam 1, and transmitting the reel 2 through the transmission part 3, the bead module 5 and the reel 2 is not arranged in a different axis, but adopts a structure arranged separately from top to bottom, and drives the reel 2 to rotate through the transmission part 3 on the side. This structure arranges the bead module 5 separately from the reel 2, and the driving force of the bead module 5 is transmitted to the reel 2 through the transmission part 3 on the side, which can not only realize power transmission, but also does not occupy the end installation space of the reel 2, so that the two ends of the reel 2 can contact the connecting part 4 and the transmission part 3 respectively without any gap, so that the gaps from the two sides of the curtain body installed on the reel 2 to the two sides of the corresponding window frame are uniform and small, preventing light leakage from the edge and achieving better shading effect.

[0037] Among them, see Figure 3 , 45. The bead pulling module 5 comprises a housing 5.1, a bead 5.2 and a bead plate 5.3. The bead plate 5.3 is rotatably arranged in the housing 5.1. The bead 5.2 is wound around the bead plate 5.3. An opening 5.1.1 is provided on the side wall of the housing 5.1 for the bead 5.2 to pass through. A transmission shaft 5.3.1 is provided on the bead plate 5.3. The transmission shaft 5.3.1 extends out of the housing 5.1 and is transmission-connected to the transmission part 3. The bead plate 5.3 is driven to rotate by pulling the bead 5.2. The bead plate 5.3 transmits the power through the transmission shaft 5.3.1. The force is given to the transmission part 3, and the transmission part 3 transmits the power to the reel 2, thereby driving the reel 2 to rotate, realizing parallel power transmission up and down, and the bead module 5 does not occupy the installation space at the end of the reel 2, so that the two ends of the reel 2 can contact the connecting part 4 and the transmission part 3 respectively without any gap, so that the curtain body installed on the reel 2 can better block light and prevent light leakage from the edge. In addition, the shape of the outer shell 5.1 fits with the inner wall of the top beam 1, which is convenient for installation and positioning. A window for the bead 5.2 to pass through is provided at the corresponding position on the top beam 1.

[0038] Among them, see Figure 2 The third end 2.1 of the reel 2 is connected to a first rotating wheel 6, and the fourth end 2.2 of the reel 2 is connected to a second rotating wheel 7. The first rotating wheel 6 is connected to the connecting part 4, and the second rotating wheel 7 is connected to the transmission part 3. The power transmitted by the second rotating wheel 7 through the transmission part 3 drives the reel 2 to rotate, and the first rotating wheel 6 plays a driven role. Since the curtain will select reels 2 of different thicknesses according to different sizes, the setting of the first rotating wheel 6 and the second rotating wheel 7 is convenient for replacement during assembly to adapt to reels 2 of different thicknesses, which is more convenient and low-cost than replacing the connecting part 4 and the transmission part 3, and is more flexible in use and assembly.

[0039] Preferably, see Figure 6 The transmission part 3 includes at least two gears meshing with each other, namely a first gear 3.1 and a second gear 3.2. The first gear 3.1 is connected to the transmission shaft 5.3.1, and the second gear 3.2 is connected to the second rotating wheel 7. The bead plate 5.3 is driven to rotate by pulling the beads 5.2. The transmission shaft 5.3.1 on the bead plate 5.3 drives the first gear 3.1 to rotate coaxially. The first gear 3.1 meshes with the second gear 3.2, and the second gear 3.2 drives the second rotating wheel 7 to rotate coaxially. The second rotating wheel 7 drives the reel 2 to rotate , thereby realizing the transmission of driving force from axial direction to radial direction and then to axial direction, which can not only realize that the bead pulling module 5 drives the reel 2 to rotate, but also can install the bead pulling module 5 separately from the reel 2, and does not occupy the installation space at the end of the reel 2 to affect the shading, wherein the transmission part 3 also includes a third gear 3.3, which is meshed between the first gear 3.1 and the second gear 3.2. When the axial distance between the first gear 3.1 and the second gear 3.2 is too large, the third gear 3.3 can play the role of transitional transmission of power.

[0040] Preferably, see Fig.14 The transmission part 3 includes a first transmission wheel 3.4, a second transmission wheel 3.5 and a transmission belt 3.6 sleeved between the first transmission wheel 3.4 and the second transmission wheel 3.5. The first transmission wheel 3.4 is connected to the transmission shaft 5.3.1, and the second transmission wheel 3.5 is connected to the second rotating wheel 7. The bead plate 5.3 is driven to rotate by the bead pulling 5.2. The transmission shaft 5.3.1 on the bead plate 5.3 drives the first transmission wheel 3.4 to rotate coaxially. The first transmission wheel 3.4 drives the second transmission wheel 3.5 to rotate through the transmission belt 3.6. The second transmission wheel 3.5 drives the second rotating wheel 7 to rotate coaxially. The second rotating wheel 7 drives the reel 2 to rotate, thereby realizing the transmission of driving force from axial to radial and then to axial, which can not only realize the bead pulling module 5 driving the reel 2 to rotate, but also can install the bead pulling module 5 separately from the reel 2 without occupying the installation space at the end of the reel 2 to affect the shading.

[0041] Among them, see Figure 7 , 8 , 11, 12, the bead module 5 is also connected to a power module, the power module is arranged in the top beam 1, and the power module is provided with a power output shaft, see Figure 4 The bead plate 5.3 of the bead pulling module 5 is provided with a transmission hole 5.3.2 that cooperates with the power output shaft. The transmission hole 5.3.2 is located on the opposite side of the transmission shaft 5.3.1 and is coaxially arranged with the transmission shaft 5.3.1. The shell 5.1 is provided with a through hole 5.1.2 corresponding to the transmission hole 5.3.2. The setting of the power-assisting module can play an assisting role, making people more labor-saving when pulling the bead 5.2 and having a better sense of use.

[0042] As a preferred option, see Figure 7 , 8, 9, 10, the power assist module is a coil spring assembly 8, the coil spring assembly 8 includes a housing 8.1, a coil spring 8.2 and a power output shaft 8.3, a part of the power output shaft 8.3 is located in the housing 8.1, and the other part of the power output shaft 8.3 is located outside the housing 8.1 and is transmission-connected to the transmission hole 5.3.2 on the bead plate 5.3, the power output shaft 8.3 can rotate relative to the housing 8.1, the coil spring 8.2 is located in the housing 8.1 and is wound around the power output shaft 8.3, when the bead 5.2 is pulled to drive the reel 2 to release the curtain body downward, the gravity direction of the curtain body is the same as the unfolding direction of the curtain body, which can play an auxiliary role, It is relatively easy to release the curtain downward. During this process, the bead 5.2 pulls the bead plate 5.3 to rotate. The bead plate 5.3 accumulates winding force through the transmission hole 5.3.2 and the power output shaft 8.3. When the curtain needs to be rolled up, the bead 5.2 pulls the bead plate 5.3 to rotate in the opposite direction. At this time, the gravity direction of the curtain is opposite to the winding direction of the curtain, and it will be more difficult to pull the bead 5.2. The winding force accumulated by the spring 8.2 can assist the bead plate 5.3 to rotate through the cooperation of the power output shaft 8.3 and the transmission hole 5.3.2, so that people will not be so strenuous when pulling the bead 5.2 to roll up the curtain.

[0043] As another preferred option, see Fig.11 , 12 , 13, the power assist module is a motor 9, and the power output shaft 9.1 of the motor 9 is in transmission connection with the transmission hole 5.3.2 on the bead plate 5.3. When in use, the motor 9 can drive the bead plate 5.3 to rotate, thereby driving the reel 2 to retract and release the curtain body, which is effortless and realizes automatic control. There is no need to manually pull the bead 5.2 to roll up the curtain body. In addition, when the motor 9 is out of power, the reel 2 can also be driven to roll up and release the curtain body by manually pulling the bead 5.2, which is more flexible to use.

[0044] The utility model arranges the bead pulling module 5 in the top beam 1, separates the bead pulling module 5 and the drum 2 up and down, and drives the drum 2 to rotate through the transmission part 3, so that the two ends of the drum 2 can contact the connecting part 4 and the transmission part 3 respectively without any gap, so that the gaps from the two sides of the curtain body installed on the drum 2 to the two sides of the corresponding window frame are uniform and small, preventing light leakage from the edges and achieving better shading effect. Secondly, by adding an assisting module, that is, a coil spring assembly 8 or a motor 9, in the top beam 1, the assisting bead pulling module 5 drives the drum 2 to rotate, which is more labor-saving to use, and adopts a modular structure, so the assembly is more flexible, consumers have more choices, and it is also very convenient for consumers to assemble it by themselves and combine and install it according to specific needs.

[0045] Unless otherwise specified, the materials, reagents and experimental equipment involved in the embodiments of the present invention are all commercially available products in the field of curtains.
