SIMPLE, GLUE-FREE MOVABLE TRACK MODEL WITH DUAL-PIN STRUCTURE

摘要

A simple, glue-free movable track model with a dual-pin structure comprises an intermediate connecting component (1), a track shoe (2), elastic pin bushes (58) and an auxiliary clamp, an elastic opening (50) is formed on a rotating shaft hole of the intermediate connecting component (1), and the intermediate connecting component (1) is spliced , in a snap-fit manner, with an intermediate rotating shaft (51) of the track shoe (2) through the elastic opening (50) back-off dowels (21) are arranged at the both ends of the track shoe (2) and are spliced with the elastic pin bushes (58) so that the elastic pin bushes (58) can be fit into the back-off dowels (21) and then securely engaged. The movable track model can realize one-time assembly, reduce manufacturing difficulty and improve manufacturing efficiency.
