Abstract

The invention provides a trundle with a height adjustment function. The trundle comprises a circular base, a U-shaped trundle rack is rotatably connected to the lower surface of the circular base, anda wheel shaft is fixedly installed on the U-shaped trundle rack; a rolling wheel rotatably sleeves the wheel shaft, a base column is fixedly installed on the upper surface of the circular base and isvertical to the circular base, and a glaze segment and a thread segment are arranged on the surface of the base column; multiple positioning grooves are formed in the glaze segment, a sleeve sleevesthe thread segment, and first thread holes are formed in the outer wall of the sleeve; first positioning screws are arranged in the thread holes, the ends of the first positioning screws are insertedin the positioning grooves, and a first connection plate is fixedly connected to the top of the sleeve and fixedly connected to the bottom of a cart body. Through the base column in threaded connection with the sleeve, the trundle has the height adjustment function, therefore, compared with the prior art, the height adjustment function of the trundle is achieved, the related structure is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of casters, in particular to a height-adjustable caster. Background technique [0002] Casters are a general term, including movable casters and fixed casters. Swivel casters are what we call universal wheels, and its structure allows 360-degree rotation; fixed casters are also called directional casters, which have no rotating structure and cannot be rotated. Usually, the two kinds of casters are used together. For example, the structure of the trolley is two directional wheels on the front, and two universal wheels near the push armrest on the back. [0003] At present, casters are widely used in trolleys, mobile scaffolds, workshop trucks, etc. The installation heights of casters used in different industries are often different, and the cost of producing casters with different heights for different usage methods is relatively high. Contents of the invention [0004] In view of this, the present invention accura...
