Variable-speed lifting simulation device for climbing machine

The utility model relates to a variable-speed lifting simulation device for a climbing machine. The variable-speed lifting simulation device comprises a male rod, a female rod, a speed reduction assembly and a lifting screw rod, the lower end of the male rod is linked with a speed reduction assembly, the speed reduction assembly is located at the end away from the male rod and linked with a lifting screw rod, and a first sliding block is in threaded linkage with the periphery of the lifting screw rod. The upper end part of the female rod is synchronously linked with the male rod in a steering manner, and the female rod can slide back and forth relative to the male rod along the axis direction of the male rod; two sets of threads are distributed on the periphery of the lifting lead screw and distributed in a staggered mode, and the screwing directions of the two sets of threads are opposite. The speed-variable lifting simulation device for the climbing machine has the advantages that the climbing simulation ef
