Abstract
The utility model relates to the field of a file containing tool, and particularly provides a road wheel used for a compact file shelf, which comprises a wheel body, and is characterized in that the cross section of a walking groove at the periphery of the wheel body is in an arc shape. Compared with the prior art, the road wheel of the compact file shelf disclosed by the utility model has the characteristics of reasonable design and the like, and the friction between the road wheel and a rail can be effectively reduced.
Description
Technical field
The utility model relates to the archives container field, and a kind of concentrated archive shelf road wheel specifically is provided.
Background technology
Concentrated archive shelf is used for industries such as each enterprise, public institution, bank, archive, museum and preserves file, archives and precious article.Intensive support body when mobile, be by handle shake generation strength, after strength being amplified, pass to the wheel shaft on chassis through the sprocket wheel on the transmission panel, the road wheel that wheel shaft drives on the chassis moves together.In the prior art, contacting of road wheel and track is plane contact, and area of contact is bigger, and friction force is big during walking, sticking easily dust, and easy to wear, the life-span is short.Shake the process of handle requires great effort especially at intensive at full load very much.
Summary of the invention
The utility model is at above-mentioned the deficiencies in the prior art, provides a kind of reasonable in design, can effectively reduce the concentrated archive shelf road wheel with the interorbital friction force.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of concentrated archive shelf road wheel, comprise wheel body, and be characterized in that the cross section of wheel body excircle walking groove is a circular arc.The contact surface that is wheel body and track is an arc surface.
Concentrated archive shelf of the present utility model is provided with circular section walking groove with road wheel, when fit circular arc face walking track uses, contact surface between walking track and the road wheel is improved to circular arc line point by in the past plane contact contacts, have following beneficial effect highlightedly:
(1) is not easy to stay dust, foreign material on the contact surface, can effectively reduces wearing and tearing, increase service life;
(2) can effectively reduce the friction force of contact surface, even in the time of intensive fully loaded, also can use very little strength that support body is moved.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model concentrated archive shelf with road wheel;
Accompanying drawing 2 is running condition scheme drawings of road wheel shown in Figure 1.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
As shown in Figure 1, concentrated archive shelf of the present utility model comprises wheel body 1 with road wheel.
The cross section of wheel body 1 excircle walking groove 2 is a circular arc, and promptly wheel body 1 is an arc surface with the contact surface of track.
As shown in Figure 2, concentrated archive shelf of the present utility model is used for being used with arc surface walking track 3 with road wheel.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
Claims (1)
