The invention discloses a lifting telescopic device. The lifting telescopic device comprises a box body, a flange plate is movably installed above the box body, and ball covers are fixedly installed on the lower right portion of the flange plate. Three sets of ball joints are arranged, the flange plate and the ball joints are connected through the ball covers, the angle of the flange plate can be adjusted by changing the height of the ball joints so as to change the angle of connecting pieces installed on the flange plate, and through the connecting mode, end equipment can be lowered and adjusted, the angle can be adjusted, and the movement characteristic needed by the end equipment is met. Lead screws are arranged in the box body, the purpose of adjusting the height is achieved in the modes that one set of lead screws are sleeved with one set of lead screws and the positions of other lead screws are adjusted through ball screw pairs, and each ball screw pair is connected with an external telescopic column through one set of lubricating shaft sleeve, so that when the positions of the internal lead screws are adjusted, the lubricating shaft sleeves can drive the external telescopic columns to move to provide protection such as dust prevention for the internal lead screws.

    本发明公开了一种升降伸缩装置,包括箱体,所述箱体的上方活动安装有法兰盘,所述法兰盘的右下方固定安装有球罩;设置三组球关节,通过利用球罩将法兰盘与球关节连接,通过改变球关节的高度,即可调节法兰盘角度,以改变安装在法兰盘上的连接件角度,通过这种连接方式,使得端部设备实现可降可调,角度可调,满足端部设备所需的运动特性;箱体内部设置丝杠,通过一组丝杠套一组丝杠的方式,再利用滚珠丝杠副调节其他丝杠的位置,以达到调节高度的目的,而每组滚珠丝杠副均通过一组润滑轴套与外部的伸缩柱连接,使得调节内部丝杠位置时,也可通过利用润滑轴套带动外部的伸缩柱进行移动,对内部的丝杠提供防尘等保护。
