An easy-to-install and stable universal wheel for a shopping cart

Abstract

The invention relates to the technical field of wheels, in particular to a convenient and stable universal wheel for shopping carts. The technical problem to be solved by the present invention is that when using a shopping cart, it feels very strenuous and does not have the function of damping, so the situation that the wheels are likely to break and the distance between the universal wheels are fixed. In order to solve the problems of the above-mentioned technologies, the present invention provides an easy-to-install and stable universal wheel for shopping carts. The present invention is mainly composed of a supporting column, a supporting telescopic mechanism, a moving mechanism, and a vibration-reducing protection mechanism, and has the ability to adjust the width. When there are obstacles or ditches in the forward direction, the shopping cart can pass through quickly and effectively, and the micro-generator supplies power to the motor to boost the shopping cart, making the user feel very relaxed and very convenient when using the shopping cart and has the function of vibration reduction. Function, when subjected to a large impact force, it is not easy for the wheel to break, which protects the safety of the universal wheel and the user.

Description

technical field [0001] The invention relates to the technical field of wheels, in particular to a convenient and stable universal wheel for shopping carts. Background technique [0002] The swivel wheel is the so-called movable caster, which is a traditional circumferential wheel with many rollers, and the roller plate is in a plane parallel to the wheel rotation axis. Mobile, its structure allows horizontal 360° rotation. Casters are a general term, including movable casters and fixed casters. Fixed casters have no rotating structure and cannot be rotated horizontally but can only be rotated vertically. These two types of casters are generally used together, such as trolleys. The structure is two fixed wheels on the front, and two movable universal wheels near the push armrest on the rear. The universal wheel refers to the bracket installed on the caster wheel that can rotate 360 ​​degrees horizontally under dynamic load or static load. There are many kinds of materials, t...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of shopping cart universal wheel that is easy to install and stable, by setting support column, support expansion and contraction mechanism, moving mechanism and shock-absorbing protection mechanism, in order to solve the problem of using the shopping cart in the above-mentioned background technology If it is laborious and does not have the function of vibration reduction, it will easily break the wheel and the distance between the universal wheels is a fixed problem.
