The invention discloses a double-position adjusting type traction seat which comprises a base and a saddle installed on the base, and a locking structure is arranged on the saddle. The base comprises two lower supports which are oppositely arranged left and right, a transverse rotating shaft which is rotationally mounted between the two lower supports, and a longitudinal rotating shaft which is rotationally connected to the middle part of the transverse rotating shaft; two supporting plates are oppositely arranged at the bottom of the saddle front and back, strip-shaped through grooves extending in the vertical direction are formed in the middles of the two supporting plates correspondingly, side supports are arranged on the opposite outer sides of the lower ends of the supporting plates correspondingly, and two lead screws symmetrically arranged on the two sides of the strip-shaped through grooves are rotationally installed between the bottom of the saddle and the side supports on the two sides. The four lead screws can be driven by a driving mechanism to rotate synchronously, the two ends of the longitudinal rotating shaft extend out of the strip-shaped through grooves in the two sides respectively and are fixedly provided with adjusting blocks, and the adjusting blocks on each side are in threaded connection with the two lead screws on the corresponding side respectively. The installation height of the traction seat can be adjusted more conveniently, flexibly and accurately.
本发明公开了一种双位调节式牵引座,包括底座以及安装在底座上的鞍座,鞍座上设有锁止结构;底座包括两个左右相对设置的下支座、转动安装于两个下支座之间的横向转轴以及转动连接于横向转轴中部的纵向转轴;鞍座的底部前后相对设置有两块支撑板,两块支撑板的中部均设置有沿竖向延伸的条形通槽,各支撑板下端的相对外侧均设置有侧支座,鞍座的底部与每侧的侧支座之间转动安装有两根对称设置于条形通槽两侧的丝杆,四根丝杆能够在驱动机构的驱动下同步转动,纵向转轴的两端分别伸出两侧的条形通槽并固定有调节块,每侧的调节块分别与对应侧的两根丝杆螺纹连接。本发明可使牵引座安装高度的调节更加方便、灵活和精确。
