Straight rack type spherical adjustable universal wheel

Abstract

The invention discloses a straight rack type spherical adjustable universal wheel, including a rolling ball, an inner barrel body coated with the rolling ball, a plurality of guiding balls in contactwith the surface of the rolling ball and arranged above the inner part of the inner barrel body, an outer barrel body, and a rocking bar connecting gears. Fixing bolts are installed on the top of theouter barrel body used for connecting with other devices, the side wall of the outer barrel body is provided with a gear opening, a gear frame is arranged on the gear opening, the gears are mounted onthe gear frame, racks are arranged on the barrel wall of a corresponding gear in the inner barrel body, the racks are meshed with the gears, and the barrel body inner height of the outer barrel bodyis higher than that of the inner barrel body combined with the rolling ball. According to the straight rack type spherical adjustable universal wheel, the rolling ball, the balls and the inner barrelbody are regarded as a universal wheel, the outer barrel body is regarded as a lifting supporting leg, the gears are matched with the racks, the lifting is controlled through the rocking bar, the structure is simple to manufacture, easy to achieve, and convenient to use, all functions of the universal wheel can be retained, and when the movement is not needed, the universal wheel is the same as ageneral table leg.

Description

technical field [0001] The invention relates to a universal wheel, in particular to a straight rack type spherical adjustable 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 i...

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.

Visible, existing universal wheel can't solve these technical problems
