Detailed Description

To make the objectives, technical solutions and advantages of the present application more clear, the present invention will be further described with reference to the accompanying drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Examples

As shown in fig. 1 to 3, in the present embodiment, a mechanical limiting device for a platform gear train steering assembly is disclosed, and it should be noted that, in the present embodiment, the terms of "first", "second", and the like are only used for distinguishing similar components, and cannot be understood as a specific limitation to the protection range. In the present embodiment, the terms of orientation such as "bottom", "top", "peripheral edge", "center", and the like are explained based on the drawings

Specifically, the mechanical limiting device of the platform wheel train steering assembly of the embodiment includes a fixed disc 1 with a hollow circular center and a U-shape, positioning holes 6 symmetrically arranged along the front end of the central axis of the fixed disc 1, a limiting pin 2 arranged at the center front end of the positioning holes 6, a dish-shaped moving block 3 arranged on the central axis of the fixed disc 1, left and right symmetrically and in dish shape, a wave screw 7 arranged at the tail of the dish-shaped moving block 3 and matched with the positioning holes 6, a movable disc 4 arranged above the fixed disc 1 and connected with the fixed disc 1 through a bearing, and a trigger pin 5 arranged on the central axis of the movable disc 4 and vertically corresponding to the limiting pin 2.
