The invention discloses a switch machine indication rod adjusting mechanism which comprises a mounting base, a worm, a worm gear and a lead screw. The worm is rotationally mounted on the mounting seat; the worm gear is rotationally mounted on the mounting seat and meshed with the worm, and a screw hole is formed in the worm gear; the lead screw is arranged in the screw hole in a penetrating mode and matched with the screw hole in a threaded mode, and the lead screw is suitable for being connected with an indication rod. The worm and gear structure is mainly used for replacing an original shaft sleeve structure with a buckle or without a buckle, the worm and gear structure has the large transmission ratio, the bearing capacity is high, transmission is stable and reliable, and particularly, the self-locking performance is achieved, so that the structural stability and safety are improved, and mechanical parts are simplified.

    本发明公开了一种转辙机表示杆调整机构,包括:安装座、蜗杆、蜗轮和丝杆;所述蜗杆转动安装在所述安装座上;所述蜗轮转动安装在所述安装座上并与所述蜗杆啮合,所述蜗轮上设有螺孔;所述丝杆穿设在所述螺孔内并与所述螺孔螺纹配合,所述丝杆适于与表示杆相连。本发明主要利用蜗轮蜗杆结构替换原来的有扣、无扣轴套结构,蜗轮蜗杆结构具有很大的传动比,而且承载能力强,传动平稳可靠,尤其是具有自锁性,使得结构稳定性、安全性得到提高,且精简了机械部件。
