Abstract

The utility model relates to a rolling wheel. A wheel body (3) which is formed by fairly rigid elastic materials is arranged at the radial middle of a supporting body (2), and the supporting body (2) is provided with a shaft hole (1). The utility model has the advantages that the simple structure is realized; not only the fault which is caused by a bearing can be avoided, but the defect that rolling wheel is formed by the homogenous material can also be avoided; smaller frictional force can be guaranteed, the long service life is realized, the low cost and the small noise are realized, and the production process is simple; thus, the utility model is novel rolling wheel.

Description

Roller

The utility model relates to a kind of all kinds of accessories that need the article of roll displacement, particularly a kind of roller that rolls of can be used on guide rail.

The application of roller is very extensive, for example curtain, drawer or all kinds of push-pull door and window, and generally the roller of Shi Yonging is an affixed elastic sleeve outside a bearing, or the roller in the homogenous material tape spool hole of making.The former roller effect is pretty good, but cost is higher, simultaneously easily advances dirt in the bearing or the temperature bearing oil viscosity that causes on the low side is bigger than normal, is to cause rolling not smooth, causes the inconvenience of use.Latter's relative cost is easy to control, the copper material of use as usual, and cost height, noise are big, but long service life, as making with nylon material, cost is low, noise is little, but working life is short, and therefore all kinds of rollers that use at present all exist deficiency separately.

Goal of the invention of the present utility model is that to disclose a kind of cost low, simple in structure, the roller that the life-span is long.

Realize that technical solution of the present utility model is as follows: at the radially middle wheel body that is provided with the elastic material formation of the suitable rigidity of tool of the support that has axis hole.The material that only need consider support during making has suitable rigidity and wear resistance, and and places in the future between the material of axle of axis hole and have less surface friction drag to get final product.

Structure of the present utility model is very simple, avoid the defective of using bearing to bring, avoid the shortcoming of the roller that homogenous material constitutes again, can use metal as support and axle, as not luring steel, as long as keep certain machining accuracy, can guarantee existing less surface friction drag, can guarantee quite long working life again, wheel body can adopt nylon, reduce cost, reduced noise again, but the while simple production process.

See also Fig. 1-Fig. 9, embodiment's of the present utility model structure is as follows: at the radially middle wheel body 3 that is provided with the elastic material formation of the suitable rigidity of tool of the support 2 that has axis hole 1; Support 2 is preferably metallic material and makes, for example do not lure steel or copper or through the general steel of antirust processing, described wheel body 3 should use than the elastic material of rub resistance to be made, as nylon or rubber-plastics material, also can use metallic material, for further improving the join strength between support 2 and the wheel body 3, particularly when wheel body 3 is nylon or rubber-plastics material, surface of contact at support 2 and wheel body 3 is to have suitable roughened surface, as have a plurality of rules or an irregular projection, or a plurality of rules or irregular indenture, when both pressure injections are one, can improve join strength between the two; Connect the strong end between support 2 and the wheel body 3 for further improving, the area of contact that increases between the two also is one of approach of considering, promptly one or more scrobicular ring 4 is arranged on the surface of the support 2 that contacts with wheel body 3, it not only can increase join strength, with the mode moulding of colding pressing, can also reduce the metal use amount as support 2, when particularly being its material with copper, reduce the use amount of copper, can further reduce cost; In long-term the use, do not cause the connection between support 2 and the wheel body 3 loosening for further improving roller, or support 2 is driven in the whole rolling process, between support 2 and the wheel body 3 bigger driving force is arranged, section configuration in the scrobicular ring 4 at support 2 middle parts is a polygonal, as quadrilateral or triangle, shape as shown in Figure 5 because the existence at polygonal angle is arranged, can not produce the possibility of the slip of structure as shown in Figure 6 between support 2 and the wheel body 3.The rolling surface of described wheel body 3 is the plane, also can be a groove 5, to adapt to different guide rail situations.For improving the intensity of whole roller, on the surface of the support 2 that contacts with wheel body 3 one or more annular projection 6 is arranged, as Fig. 8-shown in Figure 9, above-mentioned annular projection 6 can go deep into the inside of wheel body 2, both increased the area of contact between wheel body 3 and the support 2, increase frictional force, also can play the intensity that increases wheel body 3 simultaneously; At the outward edge of annular projection 6 breach 7 more than 2 is arranged, the part of wheel body 3 embeds again in the annular projection 6 like this, and both mutual interlocks increase the driving force between support 2 and the wheel body 3, same purpose, and above-mentioned projection 6 can also be a polygonal or square.

Of the present utility model simple in structure, be skillfully constructed, can adapt to multiple guide rail and multiple requirement of strength, the life-span is long, noise is little, rolling is steady.
