自动收缩桌
摘要：
本发明提供了自动收缩桌，该自动收缩桌包括升降桌面装置、支撑装置以及升降装置。本发明所述升降桌面装置设在支撑装置上，所述支撑装置设在升降装置上。所述支撑装置用于将升降桌面装置展开或合并，所述升降装置用于将支撑装置提升或是下降。本发明利用多节伸缩电动缸工作原理，即，电机经齿轮减速后，带动一对丝杆螺母，将电机的旋转运动带动推杆的往复直线运动；并结合现有技术中的机械结构展开或收缩升降桌面装置，并将升降桌面装置升降至适合的高度。
摘要（英）：

The invention provides an automatic retractable table. The automatic retractable table comprises a lifting table top device, a supporting device and a lifting device. The lifting table top device is arranged on the supporting device, and the supporting device is arranged on the lifting device. The supporting device is used for unfolding or folding the lifting table top device, and the lifting device is used for lifting or lowering the supporting device. The working principle of a multi-section telescopic electric cylinder is utilized, that is, a motor drives a pair of lead screw nuts after being decelerated by a gear, and the rotating motion of the motor drives a push rod to do reciprocating linear motion; and the lifting table top device is unfolded or folded by using a mechanical structure in the prior art, and is lifted to a proper height.
