Damping universal wheel for luggage

Abstract

The invention relates to a damping universal wheel for luggage. The damping universal wheel comprises a mounting plate, wherein mounting holes are formed in the two sides of the upper part of the mounting plate; connecting columns are connected to the interiors of the mounting holes in an inserting manner; a fixed block is arranged at one end, extending out of the each mounting hole, of the each connecting column; a shaft is arranged between the other ends, extending out of the mounting holes, of the connecting columns; traveling wheels are arranged on the shaft in a sleeving manner; a dampingpad I is arranged on the outer side face of the each connecting column and is positioned between the corresponding fixed block and the mounting plate in a sleeving manner; a stop block is arranged onthe outer side face of the each connecting column and is positioned between the mounting plate and the shaft; a damping pad II, a damping spring and a damping pad III are sequentially arranged on theouter side face of the each connecting column and are positioned between the stop blocks and the mounting plate in a sleeving manner; and through holes are formed in the two sides of the upper part of the mounting plate and are positioned outside the mounting holes; a universal wheel shaft is arranged in the middle of the mounting plate; and a bearing seat is arranged on the universal wheel shaftin a sleeving manner. The damping universal wheel disclosed by the invention has the advantages that a damping effect is improved and noise is reduced.

Description

technical field [0001] The invention relates to the technical field of universal wheels, in particular to a shock-absorbing universal wheel for bags. Background technique [0002] The universal wheel is the so-called movable caster, and its structure allows horizontal 360-degree rotation. The universal wheel is often used under the luggage to rotate 360 ​​degrees horizontally under dynamic load or static load. When the luggage is walking, the road surface is uneven, and the walking wheels will cause bumps. If there are fragile products in the luggage, the walking process will be very difficult. It is easy to shatter these fragile products and cause losses. The existing shock-absorbing universal wheels basically only use springs for shock absorption. Although the springs can slow down the bumps, they tend to resonate with bags during high-frequency operation. The effect is not optimal.
