Abstract
The invention discloses a roller, comprising a cylindrical roller body. Two side faces of the roller body are coaxially provided with roller shafts, respectively. The middle part of the roller body is provided with a first annular groove which divides the roller body into two circular support parts. Each of the support parts is provided with a second annular groove. In the roller provided by technical scheme of the invention, the middle part of the roller body is provided with the first annular groove of which the width is at least half of the width of the roller body. Therefore, when the roller body rotates during the use, the contact area between the roller body and a support surface is small, thereby reducing the frictional resistance. Furthermore, the noise during the use can be reduced. Furthermore, the support parts are provided with one second annular groove, respectively, and the width of each second annular groove is lat least half of that of each support part, so that the frictional resistance and noise can be further reduced during the use, thereby constructing a preferable home environment.
Description
Technical field
The present invention relates to a kind of roller and improve the roller that particularly a kind of surface friction drag is little, noise is little.
Background technique
The roller that common roller, particularly household are used because it is stressed generally all smaller, adopts nylon to make usually, and described roller as shown in Figure 1, comprises roller body 1; The bi-side of described roller body 1 are provided with roller shaft 2 respectively coaxially; The roller of this structure, because roller body 1 is big with the area of contact of supporting surface when rolling, thereby surface friction drag is bigger, and is harder during use, and the noise during use is bigger.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art the roller that a kind of surface friction drag is little, noise is little.
For achieving the above object, the technical solution used in the present invention is: a kind of roller comprises roller body; Described roller body is cylindrical; The bi-side of described roller body are provided with roller shaft respectively coaxially; The middle part of described roller body is provided with first circular groove; Described first circular groove is divided into roller body the supporting portion of two rings; Be respectively arranged with second circular groove on described each supporting portion.
Preferably, the width of described first circular groove is at least half of roller body width.
Preferably, the width of described second circular groove is at least half of supporting portion width.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
The described roller of the present invention program is provided with first circular groove at the middle part of described roller body; The width of described first circular groove is at least half of roller body width; When roller body is rolled when using like this and the area of contact of supporting surface little, reduced surface friction drag; Also can reduce simultaneously the noise when using; Further be to be respectively arranged with second circular groove on the described supporting portion; The width of described second circular groove is at least half of supporting portion width; More can reduce surface friction drag and noise when using, can build domestic environment better.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the sectional view of the roller of prior art;
Accompanying drawing 2 is the sectional view of roller of the present invention;
Wherein: 1, roller body; 2, roller shaft; 11, roller body; 12, roller shaft; 13, first circular groove; 14, supporting portion; 15, second circular groove.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
The described roller of the present invention program is provided with first circular groove at the middle part of described roller body; The width of described first circular groove is at least half of roller body width; When roller body is rolled when using like this and the area of contact of supporting surface little, reduced surface friction drag; Also can reduce simultaneously the noise when using; Further be to be respectively arranged with second circular groove on the described supporting portion; The width of described second circular groove is at least half of supporting portion width; More can reduce surface friction drag and noise when using, can build domestic environment better.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
