The invention relates to a center control handrail mechanism capable of hovering at will, which is characterized in that before a handrail body is controlled to turn over, a wedge block is used for extruding and moving a friction wheel to be staggered with a friction plate, and then the handrail body is turned over, so that no friction loss exists in the whole turnover process, and the service life of the mechanism is prolonged; on one hand, the control rod can prop against the wedge-shaped block to enable the friction wheel to be staggered from the friction plate so as to turn over the handrail body conveniently, on the other hand, the elastic force borne by the control rod is matched with the wedge-shaped block and the clamping piece to generate pulling force on the friction plate, and the static friction force between the friction plate and the friction wheel is enhanced when the handrail is suspended.
本发明涉及一种可任意悬停的中控扶手机构,本发明在操控扶手本体进行翻转前,利用楔形块将摩擦轮挤压移动使得其与摩擦片错开,而后进行翻转,使得翻转全程不存在摩擦损耗,从而提高了机构的使用寿命;控制杆一方面可以顶撑楔形块使得摩擦轮错开摩擦片便于对扶手本体进行翻转操控,另一方面利用控制杆受到的弹力,配合楔形块以及夹片产生对摩擦片产生拉拽力,在扶手悬停是增强摩擦片与摩擦轮之间的静摩擦力。
