Problems solved by technology

[0002] With the improvement of living standards, universal wheels have widely appeared in people's daily life, but ordinary universal wheels have only one wheel, and the wheel diameter of ordinary universal wheels is usually small for reasons of beauty, resulting in The contact area with the floor is too small, the contact surface pressure is too large, it is easy to cause the floor to wear and shorten the service life of the floor, and at the same time, the ability to overcome obstacles is insufficient, and it is difficult to move when encountering a small step

Embodiment Construction

[0029] 1. Set the combined wheel (A) with four wheels under the fixed piece (C) and the rotating shaft (B). The rotating shaft (B) deviates from the central axis (D) of the combined wheel (A), and the combined wheel (A) It is connected with the fixed part (C) through the rotating shaft (B).

[0030] 2. Set the combined wheel (A) including four sprockets or pulleys (E) and the chain belt (F) under the fixed piece (C) and the rotating shaft (B), and the rotating shaft (B) deviates from the combined wheel (A) The central axis (D), the combined wheel (A) is connected with the fixed piece (C) through the rotating shaft (B).

[0031] 3. Set the combined wheel (A) including four wheels and an obstacle-breaking wheel (G) lifted off the ground under the fixed piece (C) and the rotating shaft (B), and the rotating shaft (B) deviates from the combined wheel (A) The central axis (D), the combined wheel (A) is connected with the fixed piece (C) through the rotating shaft (B).

Abstract

The invention discloses a combined universal wheel. According to the combined universal wheel, a combined wheel comprising two or more wheels or chain wheels or belt pulleys is arranged below a fixing piece and a rotary shaft, obstacle crossing wheels or obstacle crossing chain wheels or obstacle crossing belt pulleys and a belt-shaped object such as a chain belt or a belt are arranged in the combined wheel when it is necessary, the contact area between the universal wheel and the floor and the like is increased, the pressure intensity of the contact face is reduced, so that abrasion of the floor and the like is avoided or reduced, the service life of the combined universal wheel is prolonged, and the combined universal wheel can pass through an uneven section more easily.

Description

technical field [0001] The invention relates to a universal wheel, especially a combined universal wheel, which combines a combined wheel comprising a plurality of wheels, a rotating shaft and a fixing piece. The front of the combined wheel may include an obstacle-crossing wheel or an off-road Sprockets or pulleys, the wheels can be surrounded by belts such as chain belts or belts, which solves the problem that ordinary universal wheels have too small a grounding area, excessive pressure on the grounding surface causes soft floors such as wood to wear and the wheel diameter is too small and the ability to overcome obstacles is insufficient Reduce or avoid floor wear and prolong the service life of the floor. technical background [0002] With the improvement of living standards, universal wheels have widely appeared in people's daily life, but ordinary universal wheels have only one wheel, and the wheel diameter of ordinary universal wheels is usually small for reasons of be...
