The invention discloses an automatic opening and closing pawl ratchet wheel which comprises a ratchet wheel body, a pawl body and an action piece, the pawl body is arranged close to the ratchet wheel body, and the pawl body is constructed to be in a rotating state through a rotating shaft; the acting piece comprises a machine body and an acting rod, a shifting piece connected with the acting rod is arranged on the pawl body, and a spring piece used for pushing away the pawl body when the ratchet wheel body rotates forwards is further arranged between the shifting piece and the acting rod. The technical scheme has the beneficial effects that the arranged action piece can provide power except the ratchet wheel body, so that the pawl body can be driven by the action piece to be in an open state and kept, the ratchet wheel body can reversely rotate after the pawl body is opened, and then the purpose of automatically releasing the cable is achieved.
本发明公开了一种自动开合棘爪棘轮,包括棘轮本体、棘爪本体以及动作件,所述棘爪本体靠近所述棘轮本体设置,所述棘爪本体通过一转轴构造为转动状态;所述动作件包括机体和动作杆,所述棘爪本体上设置有与所述动作杆相连的拨片,所述拨片和所述动作杆之间还设置有供所述棘爪本体被所述棘轮本体正转时推开的弹簧件。上述技术方案的有益效果为:设置的动作件能够提供除棘轮本体之外的动力,使得棘爪本体能够被动作件驱动至打开状态并保持,这就使得棘轮本体能够在棘爪本体被打开后反向转动,进而实现自动放缆绳的目的。
