Abstract
The utility model provides a roller wheel for a box, which comprises a supporting base and a tyre, wherein the supporting base comprises a pivot rotationally connected with the body of the box and a support frame connected with the lower part of the pivot; the tyre is mounted on the support frame through a wheel axle; and the support frame is positioned on one side of the axis of the pivot. By adopting the roller wheel for the box, when an operator pulls the box on the ground, the ground is hard to be in contact with the body of the box, so that the possibility of friction between the ground and the body of the box is reduced, the abrasion of the box is reduced and the strength and the flexibility are increased by adopting the vertical structure of a medial axis, thereby greatly prolonging the service life, the flexibility and the convenience of the box.
Description
Technical field
The utility model relates to the roller that is used for case and bag, relate in particular to a kind of be used for case and bag drag case and bag on the ground the time can reduce the roller of ground and case and bag body friction possibility.
Background technology
Fig. 1-5 shows the existing two-wheeled type roller that is used for case and bag.As shown in Fig. 1-5, the existing two-wheeled type roller that is used for case and bag, comprise supporting seat 1 and tire 2, supporting seat 1 comprises the pivot 3 of the casing (not shown) that rotatably is connected in case and bag and is connected the support 4 of pivot 3 bottoms that tire 2 is installed on the support 4 by the wheel shaft (not shown).Figure 11-15 shows the existing single-wheel type roller that is used for case and bag.As shown in Figure 11-15, the existing single-wheel type roller that is used for case and bag, comprise supporting seat 9 and tire 10, supporting seat 9 comprises the pivot 11 of the casing (not shown) that rotatably is connected in case and bag and is connected the support 12 of pivot 11 bottoms that tire 10 is installed on the support 12 by the wheel shaft (not shown).For case and bag are turned to conveniently when dragging walking, generally all make tire be offset to a side of pivotal axis.Though the existing roller tire that is used for case and bag is offset to a side of pivotal axis, support has occupied the both sides of pivotal axis.Because support has occupied the both sides of pivotal axis, when the user drags case and bag on the ground, ground is easy to rub with case and bag body (the case and bag body is meant the part of case and bag except that the tire of roller), thereby the wearing and tearing of case and bag have been accelerated, shortened the service life of case and bag greatly, and friction the time can produce unpleasant to hear sound.
The utility model content
The purpose of this utility model provides a kind of roller that is used for case and bag, be connected the clamping support of pivot bottom by change, a side that is placed on pivotal axis will be propped up, make that ground was difficult to contact with the case and bag body when operator dragged case and bag on the ground, thereby reduce the possibility of ground and case and bag body friction and reach the raising smooth degree, the effect of gaining in strength.
In order to address the above problem, the utility model provides a kind of roller that is used for case and bag, comprise supporting seat and tire, described supporting seat comprises the pivot of the casing that rotatably is connected in case and bag and is connected the support of described pivot bottom, described tire is installed on the described support by wheel shaft, and described support is positioned at a side of described pivotal axis.
As preferably, described support is an one chip, and described tire is two, the both sides of the described support monolithic that is placed in.
As preferably, described support is a double-disk, and described tire is one, places between the biplate of described support.
The roller that is used for case and bag that the utility model provides has following beneficial effect at least: ground was difficult to contact with the case and bag body when operator dragged case and bag on the ground, thereby reduce the possibility of ground and case and bag body friction, reduce the wearing and tearing of case and bag, changed frame mode, thereby the smooth degree and the intensity of wheels itself have been promoted, prolong the service life of case and bag greatly, and can not produce unpleasant to hear friction sound, make case and bag use more hommization.

The specific embodiment
Describe embodiment of the present utility model with reference to the accompanying drawings in detail.
Accompanying drawing shows exemplary embodiment of the present utility model.Yet exemplary embodiment can be presented as different forms, and should not think the embodiment that it is confined to illustrate in the accompanying drawing.Exactly, it is in order to make the disclosure more thorough to one skilled in the art and complete that these embodiments are provided, and expresses scope of the present utility model fully.
Therefore, example in this specification sheets and the structure shown in the accompanying drawing are a kind of preferred exemplary of the present utility model, do not represent all technological thoughts of the present utility model.The utility model can have various equivalents and modification when application.
Fig. 6-10 shows the two-wheeled type roller that is used for case and bag of the present utility model.
Shown in Fig. 6-10, the two-wheeled type roller that is used for case and bag of the present utility model comprises supporting seat 5 and tire 6, described supporting seat 5 comprises the pivot 7 of the casing (not shown) that rotatably is connected in case and bag and is connected the support 8 of described pivot 7 bottoms, described tire 6 is installed on the described support 8 by the wheel shaft (not shown), and described support 8 is positioned at a side of described pivot 7 axis.Described support 8 is an one chip, and described tire 6 is two, the both sides of described support 8 monolithics that are placed in.
Figure 16-20 shows the single-wheel type roller that is used for case and bag of the present utility model.
Shown in Figure 16-20, the single-wheel type roller that is used for case and bag of the present utility model comprises supporting seat 13 and tire 14, described supporting seat 13 comprises the pivot 15 of the casing (not shown) that rotatably is connected in case and bag and is connected the support 16 of described pivot 15 bottoms, described tire 14 is installed on the described support 16 by the wheel shaft (not shown), and described support 16 is positioned at a side of described pivot 15 axis.Described support 16 is a double-disk, and described tire 14 is one, places between the biplate of described support 16.
The two-wheeled type roller of case and bag or single-wheel type roller all is positioned at pivotal axis owing to support the side of being used for of the present utility model, so under angle of inclination A2 in use or A4 and the existing two-wheeled type roller that is used for case and bag or the single-wheel type roller angle of inclination A1 or A3 situation about equating in use, the nadir of its supporting seat and ground-surface distance H 2 or H4 are substantially equal to the twice of H1 or H3; Equal under the situation of H1 or H3 at H2 or H4, angle of inclination A2 or A4 then go out A1 greatly or A3 is many.So just reduced the possibility of ground and the contact friction of case and bag body, thereby reduced the wearing and tearing of case and bag, prolonged the service life of case and bag greatly, thereby promoted the smooth degree and the intensity of wheels itself, and can not produce unpleasant to hear friction sound.
