The linear actuator includes elongate first and second belts that cooperate to form an extractable and retractable post. Rotatable first and second belt guide members guide the turns of the first and second belts in entangled engagement, respectively. A powered actuator causes rotation of the first and second belt guide members such that the withdrawable and retractable post can be withdrawn or retracted. The base carries the powered actuator, the first and second belts, and the first and second belt guide members. The anti-rotation mechanism includes a first anti-rotation member attached to the base and a complementary second anti-rotation member attached to at least one of the first belt and the second belt, where the first anti-rotation member and the second anti-rotation member engage each other in the post to prevent rotation of the post relative to the base. The engagement of the first and second anti-rotation members around the perimeter of the post is non-punctiform.

    线性致动器包括细长的第一带和第二带,它们协作以形成可引出且可缩回的柱。可旋转的第一带引导构件和第二带引导构件相应地将第一带和第二带的各圈引导成交缠接合。动力致动器引起第一带引导构件和第二带引导构件的旋转,使得该可引出且可缩回的柱可被引出或缩回。基部承载动力致动器、第一带和第二带以及第一带引导构件和第二带引导构件。防旋转机构包括附接到基部的第一防旋转构件以及附接到第一带和第二带中的至少一个的互补的第二防旋转构件,其中第一防旋转构件和第二防旋转构件在该柱中彼此接合,以防止该柱相对于基部旋转。围绕该柱的周边第一防旋转构件和第二防旋转构件的接合是非点状的。
