The invention discloses an easy self-locking lifting stand column which comprises a stand column inner pipe, a stand column outer pipe, a motor and a transmission assembly, the stand column inner pipe is sleeved with the stand column outer pipe, the stand column outer pipe is connected with the stand column inner pipe in a sliding mode, and the motor and the transmission assembly are arranged in the stand column inner pipe. The output end of one side of the double-end motor is connected with the transmission assembly, the output end of the other side of the double-end motor is provided with a first self-locking device, and the first self-locking device comprises a first worm connected with the output end of the double-end motor, a first worm wheel matched with the first worm and a first torsional spring which is connected to the first worm wheel in a sleeving mode and rotates through the first worm wheel to tightly hold the first worm wheel. The first torsion spring tightly holds the outer wall of the first worm wheel to prevent the first worm wheel from rotating, so that the lifting stand column is self-locked by the first self-locking device, the outer pipe of the lifting stand column is prevented from automatically descending due to insufficient locking force, the stability of the lifting stand column is guaranteed, the self-locking effect is good, and the safety is high.
本发明公开了一种易自锁的升降立柱,包括立柱内管、套接在立柱内管外并与立柱内管滑动连接的立柱外管、设于立柱内管内的电机以及传动总成,电机通过传动总成驱动立柱外管升降,电机为双头电机,双头电机一侧的输出端与传动总成相连,另一侧的输出端设有第一自锁装置,第一自锁装置包括与双头电机的输出端相连的第一蜗杆、与第一蜗杆配合的第一蜗轮以及套接在第一蜗轮上通过第一蜗轮转动以抱紧第一蜗轮的第一扭簧。本发明通过第一扭簧抱紧第一蜗轮的外壁,阻止第一蜗轮转动,以实现第一自锁装置对升降立柱的自锁,防止升降立柱的外管因锁紧力不足而自动下降,保证升降立柱的稳定性,自锁效果好,安全性高。
