Stretchable rotating wheel

Abstract

The invention discloses a stretchable rotating wheel. The stretchable rotating wheel comprises a column body (1) and a plurality of arc-shaped plates (2) which are arranged outside the column body (1), moreover, the plurality of arc-shaped plates (2) can be connected to form a circular ring-shaped wheel hub, the outer surface of the column body (1) is sleeved with a sleeve body capable of slidingin the axial direction of the column body (1), moreover, the outer surface of the column body (1) is provided with a plurality of grooves (3) which are arranged in the circumferential direction, the plurality of grooves (3) are formed in the axial direction of the column body (1) in an extending mode, the sleeve body can be embedded in the grooves (3), the exterior of the sleeve body is connectedwith the arc-shaped plates (2) through connecting rods (4) correspondingly, and stretchable rods (5) capable of stretching and retracting in the axial direction are further connected between the end surface of the column body (1) and the arc-shaped plates (2). According to the stretchable rotating wheel, the effects that the diameter of the stretchable rotating wheel can be adjusted according to requirements to a certain extent, the use efficiency is improved, and the use cost is reduced are achieved.

Description

technical field [0001] The present invention relates to the field of runner structures, in particular, to telescopic runners. Background technique [0002] As a commonly used rotating structure, the runner has a wide range of applications. In some equipment, it often plays a certain guiding and supporting role, and products of different models and specifications are often processed on the same equipment, which makes it possible to choose different specifications of runners according to the actual situation of the workpiece to be processed. , and sometimes the production company often adjusts according to the customer's order. If there is a certain difference between each batch of products of the customer, it is often necessary to prepare runners of different specifications all the time, resulting in an increase in cost and a waste of resources. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a telescopic runner that can adjust it...
