New description: [New technical field] This creation is about the improvement of the scroll structure of a roller blind, especially the at least one support ring on the return spring, which is quieter and silent when used. An innovative design for the improvement of the scroll structure of the roller blind. [Prior Art] - After the curtains or louvers are installed on the window or floor-to-ceiling windows, the curtains or louvers can be properly shaded after being pulled down to prevent excessive temperature in the room. B Subsequently, a "roller blind" was developed, which can be pulled up and down vertically. When the "roller blind" is pulled down, it has a suitable shading effect to prevent the building from being exposed to excessive sunlight. Irradiation, damage to indoor items, or feeling uncomfortable for people in the room, "roller blinds" are gradually loved by the masses of consumers and then purchased and used. There is a reel structure of a roller blind, please refer to the fourth and fifth figures. The fourth figure is an exploded perspective view of the reel structure of the existing roller blind, and the fifth figure is a front cross-sectional view of the reel structure of the existing roller blind. An outer tube t (91) is disposed, a return force spring (92) is disposed in the outer tube (91), and a brake (93) and a head group (94) are respectively disposed at two ends of the outer tube (91); The tube (91) is a hollow circular tube body, and a corresponding inner inner rib (911) is protruded inwardly from the circumference of the tube body; the return spring (92) is provided with a snap ring (921) at one end, and The other end is provided with a fixing block (922); the outer periphery of the snap ring (921) is provided with a notch (9211) corresponding to each inner rib (911) of the outer tube (91), respectively The corresponding inner ribs (911) of the outer tube (91) are in combination with each other, so that when the outer tube 5 M321939 (91) is rotated, the card drive transmission ring (921) can be rotated to rotate, and the return spring (92) is twisted; The fixing block (922) has a set position hole (9221), and one end thereof protrudes to both sides to form a block (9222), and can be sleeved with the fixed shaft (931) of the brake (93). Further, the return spring (92) is internally disposed with a shaft (923) which, in addition to supporting the weight of the return spring (92), can maintain the return spring (92) on the shaft (923) The same line is twisted without offset, the shaft (923) is pivoted through the snap ring (921), and the other end is coupled to the fixed block (922); the brake (93) includes a certain axis (931), and a toothed disc (not shown) pivotally mounted on the fixed shaft (931); the fixed shaft (931) has a socket (9311) for inserting a plug (932) And a fixed sleeve hole (9312) is formed at the end of the fixed shaft (931), and two sides of the horizontal sleeve hole (9312) respectively form a card slot (9313) corresponding to the block (9222) of the fixing block (922). When the horizontal sleeve (9312) is inserted into the fixing block (922), the block (9222) of the fixing block (922) can just click on the card slots (9313) and utilize the insertion tip ( 932) correspondingly inserting the positioning hole (9221) of the fixing block (922) and the receiving hole (9311) of the fixed shaft (931), so as to prevent improper connection between the fixing block (922) and the brake (93) Relative rotation; the chainring is provided A bead chain (933) for pulling by the hand, the toothed disc can be connected with a rotating block (934), and the inner protruding strips (911) of the outer tube (91) are respectively formed on the rotating block (934). Corresponding to the embedded recessed groove (9341); the inner end of the head group (94) is also formed with a corresponding recessed groove (941) at each inner rib (911) of the outer tube. When the brake (93) pulls the bead chain (933) on the toothed disc, the rotating block (934) on the toothed disc can be rotated, and the groove (9341) of the rotating block (934) is attached to the outer tube ( 91) The rib (911) is embedded in the card, so that the outer tube (91) is followed by the 6 M321939 movement. At the same time, due to the outer tube (91), the return spring (92) is connected to the end of the snap ring (921). The gaps (9211) are just combined with the inner ribs (911) of the outer tube (9), so that the snap ring 021) can be rotated and the return spring (92) is twisted inward or toward External rotation. However, the above-mentioned conventional roller blind reel structure, when it is actually used, has a downward weight and a curved shape due to the return weight, and is easily touched with the inner circumference of the outer tube during the rotation, so noise is generated. It is unpleasant, especially in that the width of the roller blind is wider, and the longer the length of the return spring is, the more serious the above situation is, and thus it is in need of improvement. In the light of this, the creators have provided an innovative roller shutter structure improvement with the help of many years of relevant industry experience in the design and manufacturing of the industry, with a view to assisting in solving the above problems. [New content] The present invention relates to a scroll structure improvement of a roller blind, the reel structure comprising a tube having an inner circumference protruding from the inner rib, a rebounding elastic yoke disposed in the outer tube, and respectively disposed outside a brake and a head group at both ends of the tube; the return spring has a snap ring which can be combined with the inner convex strip of the outer tube, and the other end is provided with a solid block, and the inner part of the return spring is horizontally disposed with a shaft The shaft-end pivots through the snap ring, and the other end is coupled to the fixed block; the brake includes a certain shaft and a toothed disc pivoted on the fixed shaft, the fixed shaft system and the foregoing The fixing block is combined with a bead chain, and the toothed disc can be coupled with a rotating block which can be combined with the inner convex strip of the outer tube, and the main part is sleeved with at least one elastic material on the return spring. The support ring is formed; accordingly, the return spring can be supported by the support ring, and the return spring is prevented from coming into contact with the outer tube to generate noise, and the use is quieter and silent. [Embodiment] 7 M321939 The technical content of the creation, the purpose of creation and the figure of the figure that can be achieved and the details of the two are disclosed. Please refer to the drawings and roller blinds: see the first, second and third figures. The first figure shows the three-dimensional decomposition of the reel of the creation curtain. The second and third are the scroll structure i of the creation scroll. Before: the two-sided diagram, the creation is related to a roller blind.
