Description

Universal wheel component

Technical field

The utility model relates to universal wheel component.

Background technology

Existing roll wheel assembly comprises holder, support, wheel, wheel is connected with support by a transverse axis, realize each other rotation by the structure that similar bearing is installed between holder and the support, and the structure of this similar bearing generally is made up of a plurality of iron shots and iron wash, concrete structure is in the support upper end groove to be set to be used to place iron shot, on iron shot, place iron wash again, the iron wash upper end is connected with holder, the adapter shaft that also needs to open riveting by two between holder and the support fixes vertical direction, such structure more complicated, big in installation difficulty, when particularly after installing iron shot and iron wash, adapter shaft being opened riveting, need use punch press and open the riveting adapter shaft, in opening the process of riveting,, the impact of punch press forms pit because making support be impacted by iron shot easily, thereby influence the rotation alerting ability of roll wheel assembly, and riveting is opened at adapter shaft two has also increased work efficiency, the existence of a plurality of iron shots and iron wash has also increased productive costs, also not shock-resistant in practical process, service life is also shorter.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, productive costs is low, easy for installation, work efficiency is high, rotation is flexible, the roll wheel assembly of shock-resistant, long service life.

To achieve these goals, technical solution of the present utility model is such: a kind of universal wheel component comprises holder, support, wheel, wheel is connected with support by a transverse axis, connect by a vertical pivot between wherein said support and the holder, captive joint with holder in the top of described vertical pivot, vertical pivot bottom outside is provided with axle sleeve, and rotatable cooperation the between axle sleeve and the vertical pivot, match with axle sleeve in the axle mounting hole that support top is provided with.

Because in the above-mentioned technical solution, connect by a vertical pivot between support and the holder, captive joint with holder in the top of described vertical pivot, outside, vertical pivot bottom is provided with axle sleeve, the rotatable cooperation between axle sleeve and the vertical pivot, match with axle sleeve in the axle mounting hole that support top is provided with, such structure is very simple, productive costs is low, because rotatable cooperation the between axle sleeve and the vertical pivot, the rotation of universal wheel component realizes by the rotation between axle sleeve and the vertical pivot, only need when mounted vertical pivot assembled to reinstall in the axle mounting hole with axle sleeve to get final product, install very convenient; And the iron deposit pearl is not to the impact of support with impact the pit that forms, so the universal wheel component that the utility model provides has the characteristics flexible, shock-resistant, long service life of rotating.

The specific embodiment

Below in conjunction with embodiment the utility model is described in further detail.

As Fig. 1, shown in Figure 2, the utility model provides a kind of universal wheel component to comprise holder 1, support 2, wheel 3, wheel 3 is connected with support 2 by a transverse axis 4, described support 2 and hold in the palm 1 between connect by vertical pivot 5, captive joint with holder 1 in the top of described vertical pivot 5, outside, vertical pivot 5 bottoms is provided with axle sleeve 8, the rotatable cooperation between axle sleeve 8 and the vertical pivot 5, match with axle sleeve 8 in the axle mounting hole 6 that support 2 tops are provided with, this universal wheel component has simple in structure, productive costs is low, easy for installation, the work efficiency height, rotate flexibly, shock-resistant, the characteristics of long service life.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, described vertical pivot 5 middle and lower parts are provided with annular notch 7, described axle sleeve 8 is provided with annular boss 9, annular boss 9 matches with the annular notch 7 of vertical pivot 5, axle sleeve 8 outsides also are provided with barb 10 and cooperate with axle mounting hole 6 barb draw-in groove 12 clampings all around of support 2, annular boss 9 on the axle sleeve 8 matches with annular notch 7 on the vertical pivot 5, can prevent to throw off on axle 8 and vertical pivot 5 vertical directions, axle sleeve 8 exterior barbs 10 cooperate with axle mounting hole 6 barb draw-in groove 12 clampings all around of support 2, can prevent to throw off on axle sleeve 8 and support 2 vertical directions, thereby make the fixing of universal wheel component in the vertical direction, axle sleeve 8 with the embodiment that cooperates between the vertical pivot 5 can be: axle sleeve 8 adopts slightly elastomeric plastic material to make, and by external force vertical pivot 5 is clamp-oned in the axle sleeve 8 by force; Also can be: the annular boss 9 of axle sleeve 8 be made up of multi-disc sheet lug; and these lugs are the downward conical distribution of conehead; can either conveniently vertical pivot 5 be packed into and can prevent that vertical pivot 5 and axle sleeve 8 from throwing off in the sleeve 8 again effectively; therefore these are provided with, the fit system of annular boss 9 and annular notch 7 or be provided with barb realize between axle sleeve 8 and the vertical pivot 5 on the vertical direction what fix all should be protection domain of the present utility model.

As shown in Figure 1 and Figure 2, described vertical pivot 5 bottom end faces curved surface shape spherical in shape, such structure can be so that the friction between vertical pivot 5 and axle sleeve 8 bottoms be stressed more even, and is wear-resistant and friction force is little, thereby makes the long service life of universal wheel component and rotate flexibly.

As Fig. 1, Fig. 2, shown in Figure 3, described vertical pivot 5 bottoms cooperate with axle sleeve 8 bottom butts, vertical pivot 5 middle and upper parts are provided with boss 11, the upper table surface 11-1 of boss 11 matches with holder 1, boss 11 following table 11-2 add the degree of depth of the wall thickness of Upper shaft sleeve 8 bottoms greater than the axle mounting hole 6 on the support 2 to the distance between vertical pivot 5 bottom end faces, such structure setting is for when vertical pivot 5 bottom end faces abut to axle sleeve 8 bottoms, the holder 1 of the following table 11-2 of the boss 11 on the vertical pivot 5 and upper table surface 11-1 upper end breaks away from the support upper end, the friction force of whole universal wheel component only occurs in vertical pivot 5 bottom end faces and axle sleeve 8 bottoms, has avoided support 2 and holder 1 to also have friction between support 2 and the vertical pivot 5 following table 11-2 to have influence on the rotation alerting ability of universal wheel component.

As Fig. 1, Fig. 3, shown in Figure 4, described axle sleeve 8 is made up of two identical semi-circular axle sleeve sheets 13, like this when packing vertical pivot 5 into axle sleeve 8, only need get 2 identical semi-circular axle sleeve sheets 13 covers in vertical pivot 5 outsides from both direction respectively and gets final product, again axle sleeve 8 is packed in the axle mounting hole 6 of support 2 together with vertical pivot 5, very simple and fast is installed, and it is more simple that while axle sleeve 8 is formed the processing that can make axle sleeve 8 by two identical semi-circular axle sleeve sheets 13, and the tooling cost also axle sleeve 8 than integral type is low.
