[0032] As shown in Figure 5 , 6 , an easy-to-install noise-reducing sunshade curtain reel, both ends of the reel torsional spring 10 are connected with a torsional spring L-shaped hook 10-1 integrally arranged with the reel torsional spring 10; the torsional spring L-shaped hook 10-1 at one end of the reel torsional spring 10 is clamped and connected with the torsional spring tail fixing seat 6, and the torsional spring L-shaped hook 10-1 at the other end is clamped and connected with the rotating end cover 9 or the rotating iron core module 12; the torsional spring tail fixing seat 6 is provided with an L-shaped hook clamping groove matched with the torsional spring L-shaped hook 10-1; the torsional spring L-shaped hook 10-1 is clamped in the L-shaped hook clamping groove to realize the clamping connection between the torsional spring tail fixing seat 6 and the reel torsional spring 10; and the rotating end cover 9 or the rotating iron core module 12 is provided with an L-shaped hook mounting hole matched with the torsional spring L-shaped hook 10-1; the torsional spring L-shaped hook 10-1 is inserted into the L-shaped hook mounting hole to realize the clamping connection between the rotating end cover 9 or the rotating iron core module 12 and the reel torsional spring 10.

[0033] As shown in Figure 5 , 6As shown in Figure 7, an easy-to-install and noise-reducing sunshade roller has a fixing pin hole at the connection between the rotating end fixing seat 8 and the rotating end cover 9, and a fixing pin 11 is installed in the fixing pin hole; a fixing pin hole is also provided at the connection between the rotating end fixing seat 8 and the rotating iron core module 12, and a fixing pin 11 is installed in the fixing pin hole.

The rotating plastic shell 12-2 is wrapped around the outer surface of the small iron core 12-1, and the fixing pin hole on the rotating iron core module 12 passes through the small iron core 12-1 and the rotating plastic shell 12-2.

[0035] When working, first install the sunshade roller. Figure 1 As shown in the diagram, install the reel spring pin 2, return spring 4, and reel O-ring 5 from the opening at one end of the reel, and combine them with the spring pin fixing seat 3 to form a damping elastic assembly. Align the two ends of the reel torsion spring 10 with the torsion spring tail fixing seat 6 and the rotating end cover 9 respectively. The torsion spring L-shaped hooks 10-1 are snapped into the L-shaped hook mounting slots to achieve a snap-fit ​​connection between the torsion spring tail fixing seat 6 and the reel torsion spring 10. The torsion spring L-shaped hooks 10-1 are inserted into the L-shaped hook mounting holes to achieve a rotating end cover 9 or rotating core mold. Block 12 is snapped into the torsion spring 10 to form a moving assembly; the damping elastic assembly and the rotating end fixing seat 8 are installed and fixed to the groove inside the inner tube 1 of the reel to form a static assembly; a rubber silencing tube 7 is installed on the moving assembly and installed with the static assembly to form a reel; the rotating end of the reel is rotated to store corresponding force, and the torsion spring 10 of the reel is controlled by the rubber silencing tube 7 during the force storage process to generate noise due to the lengthening and twisting of the force storage.
