电动执行器及其快速释放机构

Electric actuator and fast releasing mechanism thereof
Abstract:
In an electric actuator (100), a fast releasing mechanism (30) includes a rotary base (31), a coupling ring (32), a sleeve (34), and a clutch device (36). The coupling ring (32) rotates with the rotary base (31). Locking slots (322) are disposed on the coupling ring (32). The rotary base (31) can rotate with respect to the sleeve (34). Chain slots (343) communicating with the locking slots (322) are disposed on the sleeve (34). The clutch device (36) is correspondingly sleeved around the sleeve (34). Raised ribs (361) slidably connected to the locking slots (322) and the chain slots (343) are disposed on the clutch device (36). The sleeve (34) can be selected to move together with or move separately with the rotary base (31) by means of the axial movement of the clutch device (36).
Abstract(Chinese):

在电致动器（100）中，快速释放机构（30）包括旋转底座（31），联接环（32），套筒（34）和离合器装置（36）。 联接环（32）与旋转底座（31）一起旋转。 锁定槽（322）设置在联接环（32）上。 旋转底座31可以相对于套筒34旋转。 与锁定槽（322）连通的链槽（343）设置在套筒（34）上。 离合器装置（36）相应地围绕套筒（34）套管。 可滑动地连接到锁定槽（322）的凸肋（361）和链槽（343）设置在离合器装置（36）上。 可以选择套筒（34）通过离合器装置（36）的轴向运动与旋转底座（31）一起移动或与之分开移动。
