Shock-absorbing universal wheel for luggage

Abstract

The invention relates to a shock-absorbing universal wheel for a luggage. The shock-absorbing universal wheel for the luggage comprises a support, a supporting bracket, a roller and a driving support, wherein the roller is connected with the supporting bracket through a horizontal shaft; the supporting bracket and the support are connected through a vertical shaft; the upper part of the vertical shaft is fixedly connected with the support; the lower part of the vertical shaft is in rotatable fit with a shaft mounting hole formed on the upper part of the supporting bracket; a roller through hole and an installation through hole are formed in the driving support; the supporting bracket is connected with the driving support in a rotatable way through the installation through hole; the roller is connected with the driving support through a horizontal shaft which is arranged in the roller through hole; one side of the driving support, which is opposite to the roller through hole, is provided with a platform surface; and the platform surface is connected with an elastic device which stops the platform surface from moving downwards. Due to the stopping effect of the elastic device, the weight of the luggage and the acting force of the elastic device are balanced, so that the shock-absorbing effect is achieved; and the shock-absorbing universal wheel for the luggage has strong integral structural performance and excellent shock-absorbing performance, and can be interchanged with an ordinary universal wheel seat.

Description

technical field [0001] The invention relates to a case and bag accessory, in particular to a case and bag shock-absorbing universal wheel and a case that reduce the vibration of the case. Background technique [0002] The existing common special universal wheels for bags can make the bags move in any direction in the same plane, thereby saving people's physical strength and facilitating the transportation of luggage. Although there are many kinds of traditional universal wheels with different structures, they basically do not have the function of shock absorption, so it will cause discomfort caused by the vibration of the user's hand when dragging, especially when encountering steps. , It is easy to cause damage to the box and the contents of the box. In order to solve the existing defects, it is necessary to design a case and bag universal wheel with low noise, reliable performance and shock-absorbing function to solve the above-mentioned needs. There are shock-absorbing ...

AI Technical Summary

Problems solved by technology

There are shock-absorbing universal wheels that are widely used in other fields, that is, shock-absorbing universal wheels that are often encountered in our lives, such as luggage carts, baby carriages, carts, etc., this kind of shock-absorbing universal wheels Due to the complex structure and large size of the wheel, the production cost is correspondingly high, so it cannot be applied to luggage.

In the prior art, after searching, the shock-absorbing universal wheels for bags have not yet been found.
