The invention belongs to the technical field of seat sliding rails, and particularly relates to a seat sliding rail adjusting device. The seat sliding rail adjusting device comprises a power device, a transmission mechanism and a sliding rail, the transmission mechanism comprises an inhaul cable, a worm gear, a worm, a separable threaded piece, a lead screw and a driving support, a first locking structure is arranged on the outer wall of the separable threaded piece axially fixed relative to the upper sliding rail, and the separable threaded piece comprises at least two sub threaded pieces; an elastic ring is arranged at the holding end of the separable threaded piece in a sleeving mode. The inhaul cable is used for pulling the driving support to move axially, and an elastic reset piece is arranged between the inhaul cable and the upper sliding rail. The worm gear is rotationally installed on the installation part of the driving support, a second locking structure is arranged on the worm gear, the separable threaded part can be inserted into an installation hole of the worm gear when the sub-threaded part is tightly held and is in threaded connection with the lead screw, and a conical structure is arranged on the side, facing the opening end, of the separation part of the driving support. The conical structure can be inserted into the inner threaded hole of the opening end so that the sub-threaded piece can be separated from the lead screw.

    本发明属于座椅滑轨技术领域,特别是涉及一种座椅滑轨调节装置。一种座椅滑轨调节装置包括动力装置、传动机构和滑轨,传动机构包括拉索、蜗轮、蜗杆、可分离螺纹件、丝杆和驱动支架,相对于上滑轨轴向固定的可分离螺纹件的外壁上设置有第一锁止结构,可分离螺纹件包括至少两个子螺纹件,可分离螺纹件的抱紧端上套设有弹性圈;拉索用于拉动驱动支架轴向移动,拉索与上滑轨之间设置有弹性复位件;蜗轮转动安装在驱动支架的安装部上,蜗轮上设置有第二锁止结构,可分离螺纹件能够在子螺纹件抱紧时插入蜗轮的安装孔内并与丝杆螺纹连接,驱动支架的分离部朝向张开端的一侧设置有锥形结构,锥形结构能够插入张开端的内螺纹孔中,以使子螺纹件脱离丝杆。
