Abstract
The invention discloses an eccentric shaft type clearance adjusting mechanism. The eccentric shaft type clearance adjusting mechanism comprises an outer door frame, a bottom plate assembly, eccentric shaft assemblies and wheels. Sliding trolley vertical plates are symmetrically arranged on the two sides of the outer door frame. The first wheels, the first eccentric shaft assemblies, the second eccentric shaft assemblies and the second wheels are arranged on the sliding trolley vertical plates from left to right in sequence. The centers of the first wheels and the centers of the second wheels are located on the same horizontal plane. The centers of the first eccentric assemblies are slightly higher than the first wheels. The centers of the second eccentric assemblies are slightly lower than the first wheels. The front end of the bottom plate assembly is provided with a left C-shaped guide rail and a right C-shaped guide rail which are symmetric. The first wheels, the first eccentric shaft assemblies, the second eccentric shaft assemblies and the second wheels on the two sides are located in the left C-shaped guide rail and the right C-shaped guide rail respectively. According to the eccentric shaft type clearance adjusting mechanism, the clearances between the first wheels and the second wheels and the upper surfaces and the lower surfaces of the C-shaped guide rails can be adjusted by adjusting the positions of the eccentric shaft assemblies, and the reliability of a door frame system is improved.
