Description

Roll wheel assembly

Technical field

The utility model relates to roll wheel assembly, relates in particular to the roll wheel assembly of case and bag.

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 roll wheel assembly 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, the vertical pivot bottom turns with the axle mounting hole that support top is provided with and cooperates.

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, the vertical pivot bottom turns with the axle mounting hole that support top is provided with and cooperates, such structure is very simple, productive costs is low, cooperates because vertical pivot and axle mounting hole are rotatable, therefore only need when mounted to install very convenient getting final product with holding in the palm captive joint to reinstall in the axle mounting hole on the vertical pivot; And the iron deposit pearl is not to the impact of support with impact the pit that forms, so the roll wheel assembly 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, Fig. 2, shown in Figure 3, the utility model provides a kind of roll wheel assembly 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

5,6 rotatable cooperations of an axle mounting hole that vertical pivot 5 bottoms and support 2 tops are provided with, that this roll wheel assembly has is simple in structure, productive costs is low, easy for installation, work efficiency is high, rotation is flexible, the characteristics of shock-resistant, long service life.

As Fig. 1, Fig. 2, shown in Figure 3, described vertical pivot 5 middle and lower parts are provided with annular notch 7, support 2 is provided with pin-and-hole 8, described pin-and-hole 8 is corresponding with annular notch 7 positions of vertical pivot 5, be provided with a lateral pin 9 in the pin-and-hole 8, the part of lateral pin 9 snaps in the annular notch 7 and matches with annular notch 7, this structure can either play and prevent that vertical pivot 5 from deviating from the effect in axle mounting hole 6, can also play the function of flexible dismounting, in long use, general wheel 3 and transverse axis 4 the easiest damages and do not hold in the palm 1 fragile, roll wheel assembly in the past can only wholely be changed, and the roll wheel assembly that the utility model provides can come out 9 of lateral pins will hold in the palm 1 related vertical pivot 5 one to pull away from the axle mounting hole 6 of support 2 again, change the accessory of a new support 1 band transverse axis 4 and wheel 3, can re-assembly and obtain roll wheel assembly in working order, the characteristics that the roll wheel assembly that having embodied the utility model provides is easy to safeguard.

As Fig. 1, Fig. 2, shown in Figure 3, described 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 are to the degree of depth of the distance between vertical pivot 5 bottom end faces greater than the axle mounting hole 6 on the support 2, such structure setting is when abutting to 6 bottoms, axle mounting hole of support 2 at vertical pivot 5 bottom end faces, 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 roll wheel assembly only occurs in 6 bottoms, axle mounting hole of vertical pivot 5 bottom end faces and support 2, 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 roll wheel assembly.

As Fig. 1, Fig. 2, shown in Figure 3, 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 the axle mounting hole 6 be stressed more even, and is wear-resistant and friction force is little, thereby makes the long service life of roll wheel assembly and rotate flexibly.

As Fig. 1, Fig. 2, shown in Figure 3, the annular notch 7 upper recess surface 7-1 of described vertical pivot 5 to the distance between vertical pivot 5 bottom end faces greater than the distance of pin-and-hole 8 upper surfaces between 6 bottoms, axle mounting hole, less than the distance of pin-and-hole 8 lower surfaces between 6 bottoms, axle mounting hole, no matter such structure can avoid the upper recess surface 7-1 of lateral pin 9 with annular notch to the annular notch 7 concave surface 7-2 of vertical pivot 5 effectively when lateral pin 9 is installed or after installing lateral pin 9 to the distance between vertical pivot 5 bottom end faces, thereby the rotation alerting ability that friction has influence on roll wheel assembly takes place between the concave surface 7-2.

As shown in Figure 3, Figure 4, the another kind of embodiment that the utility model provides, be provided with annular iron wash 10 between vertical pivot 5 bottom end faces and 6 bottoms, axle mounting hole, annular iron wash 10 can play wear-resistant, impact-resistant effect, area of contact friction force littler, each other is littler between vertical pivot 5 and the iron wash 10 simultaneously, and the rotation of roll wheel assembly will be more flexible.
