The invention discloses an electric lifting column with a release function, which comprises a first cover plate, an inner pipe fixedly connected with the first cover plate, a second cover plate, an outer pipe fixedly connected with the second cover plate, and a driving mechanism for driving the inner pipe and the outer pipe to stretch out and draw back relatively, the nut is connected with the second cover plate; the motor assembly can be in transmission connection with the lead screw assembly so as to drive the lead screw to rotate; the buffer component is connected with the first cover plate and the second cover plate; the releasing mechanism is used for connecting or separating the lead screw assembly and the motor assembly; when the lead screw assembly is separated from the motor assembly, the lifting column is in a release state, and the inner pipe and the outer pipe are driven by the buffering component to stretch out and draw back relatively. The electric lifting column provided by the invention can realize quick lifting under the condition of no electric power.
本发明公开了一种带释放功能的电动升降柱,包括第一盖板、与所述第一盖板固定连接的内管、第二盖板、与第二盖板固定连接的外管,以及驱动内管与外管相对伸缩的驱动机构,驱动机构包括:丝杆组件,包括丝杆及与丝杆螺纹连接的螺母,螺母与第二盖板相连接;电机组件,其可与丝杆组件传动连接,以带动丝杆转动;缓冲部件,其连接第一盖板与第二盖板;释放机构,其用于连接或分离丝杆组件与电机组件;当丝杆组件与电机组件相分离,升降柱处于释放状态,内管与外管在所述缓冲部件带动下相对伸缩。本发明提供的电动升降柱,可在没有电力情况下实现快速升降。
