Roller shutter sunshade without rewinding impact force
The invention discloses a roller shutter sunshade without rewinding impact force, which retains components such as a storage box, a left end cover of the storage box, a right end cover of the storage box, a reel, a handle, a channel and the like in the prior art, abandons a springback pre-stressing torsion spring in the prior art, and is provided with springback impact force eliminating devices at two ends of the roller shutter sunshade. The roller shutter sunshade comprises a rope wheel, a balance torsion spring, a pulley block, a pull rope and other components, so friction resistance is reduced when a sunshade curtain is opened, the impact force is greatly weakened when the sunshade curtain is rewound, and the sunshade cloth of the roller shutter sunshade curtain can stay at any position.
本发明公开了一种无回卷冲击力的卷帘遮阳帘，保留现有技术中的收纳盒、收纳盒左右端盖、卷轴、拉手、槽道等组件，并舍弃了现有技术中的回弹预加力扭簧，在卷帘遮阳帘的两端设置了消除回弹冲击力装置，包括绳轮、平衡扭簧、滑轮组、拉绳等构件，使得遮阳帘在开起时摩擦阻力减小，在回卷时冲击力被极大程度削弱，而使得卷帘遮阳帘的遮阳布能够停留在任意位置。
