The invention discloses a vertical shaft hovering assembly of a sample injector. The upper end and the lower end of a sliding shaft are respectively fixed with a rack; the linear sliding bearing is slidably arranged outside the sliding shaft in a sleeving manner; a bearing seat is fixedly sleeved outside the linear sliding bearing; the spring is arranged outside the sliding shaft in a sleeving mode and located above the linear sliding bearing. The upper end of the spring abuts against the rack, and the lower end abuts against the bearing seat. The fixed pulley assembly is fixed to the rack, the movable pulley assembly is rotatably installed on the movable pulley assembly fixing piece, and the movable pulley assembly fixing piece is fixedly connected with the bearing seat. One end of the synchronous belt is fixed on the rack; and the other end of the synchronous belt bypasses the movable pulley assembly and the fixed pulley assembly and then is fixed with a load of the vertical shaft assembly of the sample injector. According to the invention, the installation occupied space is reduced, and the overall quality of the equipment can be greatly reduced.

    本发明公开了一种进样器垂直轴悬停组件,滑动轴的上端和下端分别与机架固定;直线滑动轴承可滑动地套设在滑动轴的外部;直线滑动轴承的外部固定套设有轴承座;弹簧套设于滑动轴的外部并位于直线滑动轴承的上方;弹簧的上端与机架相抵,下端与轴承座相抵;定滑轮组件固定于机架,动滑轮组件可转动地安装于动滑轮组件固定件,动滑轮组件固定件与轴承座固定连接;同步带的一端固定于机架;同步带的另一端绕过动滑轮组件和定滑轮组件后与进样器垂直轴组件的负载相固定。本发明减少了安装占用空间,并且可使得设备整机质量大幅度下降。
