Problems solved by technology

[0003] The disadvantage of this structure is that due to the small connection diameter between the rotating shaft and the spokes, a small radius of curvature is formed, resulting in faster mutual wear, reducing the working life of the entire walking wheel, and ultimately reducing the trouble-free working time of the entire vacuum cleaner

Embodiment Construction

[0014] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0015] The walking wheel of the vacuum cleaner which uses steam to heat food of the present invention is as figure 1 , 2 , 3, including: wheel rim 3, wheel spoke 2 and gland 4, wherein, wheel rim 3 is a ring structure, and the inner ring side of the wheel rim is provided with a descending step 31 facing the vacuum cleaner body; wheel spoke 2 is circular The plate structure (the middle part can be hollowed out) is embedded in the depression formed by the rim step 31, and the axial end surface and surface of the spoke form a clearance fit with the surface of the step 31 of the rim, so that the rim 3 rotates around the spoke 2 The spokes are made of polyoxymethylene (POM) to ensure the wear resistance of the spokes. The end ...

Abstract

The invention discloses a walking wheel of a dust collector. The walking wheel comprises a wheel rim, a wheel spoke and a gland, wherein the wheel rim is of a circular ring structure; one side face, facing a dust collector body, of the inner ring of the wheel rim is provided with a descending ladder; the wheel spoke is of a round plate structure which is embedded in a pit formed by the ladder of the wheel rim; the axial end face and the surface of the wheel spoke are in clearance fit with the ladder surface of the wheel rim, so that the wheel rim can rotate around the wheel spoke; screw holes are formed in the end face of the wheel spoke, and the wheel spoke is fastened with and connected to the dust collector body by virtue of screws; the gland is of a round thin-wall structure; the diameter of the gland is more than the diameter of the wheel spoke and is less than the diameter of the outer ring of the wheel rim; the gland and the wheel rim are connected by virtue of fasteners or screws; the wheel rim and the gland, restricted by the wheel spoke, can rotate around the wheel spoke; and by connecting the wheel spoke and the wheel rim in an embedded mode, the curvature of rotating connection between the wheel rim and the wheel spoke is reduced, so that the rotating connection between the wheel rim and the wheel spoke is more reliable; therefore, the working service life of the entire walking wheel is prolonged and the failure-free operating time of the entire dust collector is finally prolonged.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a walking wheel of the vacuum cleaner. Background technique [0002] At present, the existing vacuum cleaners are usually equipped with walking wheels. Under the rolling support of the walking wheels, the vacuum cleaner can be smoothly pushed or dragged to the working position; the existing walking wheels usually include rims, spokes and axles; . [0003] The disadvantage of this structure is that due to the small connection diameter between the rotating shaft and the spokes, a small radius of curvature is formed, resulting in faster mutual wear, reducing the working life of the entire walking wheel, and ultimately reducing the trouble-free working time of the entire vacuum cleaner. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned defects in the prior art. The present invention provides a traveling wheel of a vacuum cleaner without a...
