Lifting mechanism for preventing shutters from self-falling
The invention discloses a lifting mechanism for preventing shutters from self-falling. The lifting mechanism comprises a lifting shell and a plurality of magnetic sheets arranged on the lifting shell,and further comprises a pulley arranged at one end of the lifting shell, wherein grooves are formed in the two ends of the lifting shell, elastic mechanisms are arranged in the grooves, and each elastic mechanism comprises rollers, a baffle plate and a spring, the rollers are arranged on the two sides of the corresponding baffle plate through short shafts, and each spring is arranged under the corresponding baffle plate; and an anti-slip strip convenient to push is arranged on the side face of the lifting shell, a plurality of first protrusions are evenly arranged on the back face of the lifting shell at intervals, and the first protrusions are matched with second protrusions arranged on the front face of an anti-slip bottom plate. The lifting mechanism is reasonable in structural design,economical and practical, the mutually embedded state between the first protrusions on the back face of the lifting shell and the second protrusions on the front face of the anti-slip bottom plate isadjusted through the elastic mechanisms so as to stably ascend and descend, and self-falling damage caused by overweight of the shutters is avoided.
本发明公开一种防止百叶自坠的升降机构，包括升降壳体、设置在升降壳体上的若干磁片，还包括设置在升降壳体一端的滑轮，所述升降壳体两端设有凹槽，所述凹槽内设置弹性机构，所述弹性机构包括滚轮、挡板和弹簧，所述挡板通过短轴将滚轮设置在两侧，挡板正下方设置弹簧；所述升降壳体侧面设置便于推动的防滑条，升降壳体背面均匀间隔设置若干凸起一，所述凸起一和防滑底板正面设置的凸起二相互配合；本发明结构设计合理、经济适用，利用弹性机构调节升降壳体背面凸起一与防滑底板凸起二之间相互嵌入的状态，以此来稳固升降，避免百叶过重而自坠损坏。
