Straight tube pin hook type spherical omnidirectional wheel

Abstract

The invention discloses a straight tube pin hook type spherical omnidirectional wheel which comprises a rolling sphere, an inner tube body covering the rolling sphere, a plurality of movement-guidingrolling balls and an outer tube body, wherein the movement-guiding rolling balls are arranged at the inner upper part of the inner tube body and in contact with the surface of the rolling sphere; a fixing bolt is mounted on the top of the outer tube body and used for connecting to other devices; pin hook assemblies are arranged on the outer circumference of the outer tube body; the pin hook assemblies comprise fixing frames and pin hooks; the pin hooks are mounted on the fixing frames and pivoted on the fixing frames; a pin hook groove is arranged in the outer tube body; hooks of the pin hooksare utilized to penetrate into the pin hook groove and to be pressed against the top surface of the inner tube body; and the tube body inner height of the outer tube body is greater than the height of the inner tube body and the rolling sphere after combination. In the straight tube pin hook type spherical omnidirectional wheel, the rolling sphere, the rolling balls and the inner tube body are used as the omnidirectional wheel; the outer tube body is used as a lifting support leg and supported by a compression spring; and a guide protrusion cooperates with a guide groove. By virtue of the pinhook assemblies, the straight tube pin hook type spherical omnidirectional wheel can not only preserve all functions of the omnidirectional wheel but also realize the same function of an ordinary table leg when movement is not required. The structure is simple to manufacture, easy to implement and convenient to use.

Description

technical field [0001] The invention relates to a universal wheel, in particular to a straight pin hook type spherical universal wheel. Background technique [0002] The swivel caster is a movable caster. Its structure allows 360-degree rotation horizontally. It is often used on tables, chairs, counters, equipment and other institutions that require movement. The structure of universal wheel has the combination of fixed frame, movable frame and wheel, and wheel has roller and ball etc. The purpose of these structures is to make the universal wheel freely realize 360 ​​degree rotation. However, its movement is too flexible, causing it to move when it is not needed. In order to solve this problem, in the prior art, a locking mechanism is provided on the wheel to lock the wheel so that it does not move, but in fact, because the wheel is easy to move, this locking mechanism cannot realize the desired Effect. For example, after a counter, table or equipment is placed in place...

However, its movement is too flexible, causing movement when it is not needed

In order to solve this problem, in the prior art, a locking mechanism is provided on the wheel to lock the wheel so that it does not move, but in fact, because the wheel is easy to move, this locking mechanism cannot realize the desired Effect

For example, after a counter, table or equipment is placed in place, the user does not want it to move. However, a simple external force may cause it to move, and it is easy to cause damage to the locking mechanism.
