In the above-mentioned caster mounting structure that reduces screw fixation, as a further and more specific scheme, the location through interference fit can play certain fixed action.
Furthermore, the bottom of the moving part bottom plate is fixedly connected with at least one hollow column, and the top of the hollow column is provided with a first threaded hole.
In foretell a reduce truckle mounting structure of screw fixation, as further scheme, because the connecting plate is located the reference column, consequently there is certain distance between the bottom of connecting plate and moving part bottom plate, the hollow cylinder of spiro union department installation can make the height of connecting plate spiro union department keep unanimous with the height of location department, is favorable to the connecting plate installation stable.
Furthermore, the hollow column body comprises a hollow base column and a circular bottom plate, and the hollow base column is fixedly installed on the circular bottom plate.
In foretell truckle mounting structure who reduces screw fixation, as further scheme, because hollow cylinder is the main fixed position of connecting plate, circular bottom plate plays the reinforcement effect, improves hollow cylinder's structural strength.
Furthermore, a plurality of convex ribs are fixedly arranged at the bottom of the bottom plate of the moving part and support the connecting plate.
In foretell truckle mounting structure who reduces screw fixation, as further scheme, protruding muscle can share the pressure that reference column and hollow foundation bore bear, improves the life of truckle.
Furthermore, a plurality of gaps are formed in the convex ribs, and the connecting plate is positioned in the gaps.
In the caster wheel mounting structure for reducing screw fixation, as a further scheme, the notch plays a role in positioning and shares the stress in the horizontal direction on part of the positioning column and the hollow base column.
