New description: [New technical field] This creation provides a roller blind with a damping device, especially a damping structure that slows the rebound speed of the roller blind. [Prior Art] Conventional roller blinds are disclosed in the new case of Bulletin No. 165270 "Improvement of Brake Roller Structure", Announcement No. 308851 "Improvement of Rolling Curtain Curtain Structure", including pivoting on both sides of the frame. a reel between one end, a curtain attached to the reel at one end, and a retracting device and a braking device installed in the reel; when the curtain is rolled down to a position, the braking device will The cloth curtain is automatically formed into a positioning; and when the cloth curtain is to be retracted, the user only needs to pull the cloth curtain with a short force to release the locking of the braking device, and at the same time, the winding device has a spring The elastic force will make the curtain automatically roll up, which is quite convenient in operation. Although the conventional roller blind structure has the advantage of being convenient to operate, the rebound process that is wound up in the past often has a problem that the speed is too fast to cause an impact track and generate noise. For this reason, there is also a structure which can slow down the rebound speed of the roller blind, as disclosed in the new patent No. 484,397 "Improvement of the curtain winding buffer device", which is composed of an outer casing, a sleeve, an outer casing, and a cover. The body and the rotating block are composed; wherein the center of one end of the outer casing is an engaging rod of the hole, the inner top edge of the outer end is provided with a concave annular surface, the concave annular surface and the inner portion are hollow sections, and the M305849 protruding rod is protruded from the center of the inner bottom edge. The center of the barrel-end is dug with a round hole, so that a slight gap is formed between the hollow sections of the sleeve end plate, and lubricating oil can be injected into the periphery of the sleeve and the hollow section; The hole is sleeved in the hollow end of the outer end of the outer casing, so that the convex rod of the inner bottom edge of the outer end of the outer casing is disposed, and the other end is provided with a flange that is higher than the end of the flange. The oil seal is sleeved to resist the flange stop. At the same time, the pressure ring body at one end of the cover body is resisted. 2. The shaft with a central hole at the center thereof is surrounded by a spring, so that the outer edge of the shaft is advantageous. One end sleeve of the outer casing; the outer body of the outer casing A channel is formed on the circumference of the body ring, and when the outer sleeve is sleeved into the sleeve section, the protruding rod of the inner bottom end is embedded in the central hole of the central shaft of the sleeve, and the end of the outer spring of the shaft is protruded. Extending the locking shape in the channel, so that when the outer casing rotates in the clockwise direction, the spring can be opened outwardly to facilitate the reduction, and the outer end of the guide block is provided with a long block. The central hole of the cover body is fixed by the sleeve; - one end of the cover body is provided with a seat ring body body. The inner diameter of the pressure ring body is resisted by the oil seal which is placed in the concave arc ring edge disposed at the other end of the sleeve, and the other end is sleeved on the outer casing. The concave annular surface of the body is integrated with the sleeve; the one end of the rotating block is provided with an elongated hole of the same shape for the outer end of the outer end of the outer guiding rod of the outer casing; When the curtain fabric is to be retracted, it will be hindered by the lubricating oil outside the sleeve, and the speed of the curtain fabric winding will be slowed down. 6

One end. According to the creation of the damper device 6, in the implementation, the rotation of the 243 (for example, clockwise direction) causes the curtain to be lowered: the housing 61 will be driven, and in this state, as shown in the tenth figure The coil spring 63, which is coupled to the positioning member, is outwardly loosened relative to the rotation of the outer casing, and is not clamped on the plunger 622 of the piston. Therefore, the rotation of the outer casing 61 is generated. a resistance sufficient to affect the rotation of the reel: force; and when the reel 43 is rotated (for example, counterclockwise) to cause the curtain 41 to be wound up, the ejection shell 61 is also driven, and in this state The rotation of the coil spring 63 3 relative to the outer casing 61 is inwardly contracted, so that it is clamped on the plug rod 622 of the piston, so that the piston cannot be smoothly driven by the outer casing 61, so the rotation of the outer casing 61 will be affected. The disturbance of the damping oil 67 results in a damping force that is sufficient for the speed of rotation of the reel to achieve an effect of avoiding impact and reducing operational noise. As shown in the second and fifth figures, in the present embodiment, the present roller blind assembly 4 further includes a one-way transmission device 7 so that the reel 43 is used for the upward winding process. The bead chain 34 that drives the rotation of the reel 31 is not subjected to the rotation. Because the one-way transmission 7 will be another 12
