Abstract
The utility model discloses a roller. The roller comprises a cylindrical roller body; one side surface of the roller body is fixedly connected with a cylindrical connection bulge; a central axial hole is formed in the roller body and the connection bulge in the thickness direction; the thickness of the connection bulge is greater than the thickness of the roller body; the outer profile surface of the roller body is provided with overlapping curves; the side surface of the connection bulge further has a conical hole communicated with the central axial hole; the size of the conical hole is greater than the size of the central axial hole. The thickness of the connection bulge is greater than the thickness of the roller body, and the intensity between the connection bulge and the roller body is increased; the outer profile surface of the roller body is provided with the overlapping curves, therefore, the anti-slip performance is enhanced while the intensity is improved.
Description
Technical field
The utility model relates to a kind of roller.
Background technique
Roller of the prior art, comprise cylindrical roller wheel body, one side of described roller wheel body is fixedly connected with columniform connection bump, be provided with central shaft hole along its thickness direction on described roller wheel body and described connection bump, usually the too small join strength that makes of thickness of connection bump is inadequate, the outer surface of roller wheel body is smooth arc surface in addition, and its surface strength is not high, and cling property is poor.
The model utility content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of roller is provided, and improves intensity, and skid resistance is good.
For achieving the above object, the technical solution of the utility model has been to provide a kind of roller, comprise cylindrical roller wheel body, one side of described roller wheel body is fixedly connected with columniform connection bump, be provided with central shaft hole along its thickness direction on described roller wheel body and described connection bump, the thickness of described connection bump is greater than the thickness of described roller wheel body, the outer surface of described roller wheel body is provided with reticulate pattern, the side of described connection bump also offers the cone shape hole be connected with described central shaft hole, the size of described cone shape hole is greater than the size of described central shaft hole.
As preferably, described reticulate pattern is grid-like.
As preferably, on described central shaft hole, offer keyway.
As preferably, described keyway is rectangle groove or dovetail groove.
As preferably, the surface of described central shaft hole is provided with wearing layer.
Advantage of the present utility model and beneficial effect are: the thickness that the thickness of connection bump is greater than roller wheel body increases its join strength, and on the outer surface of roller wheel body, reticulate pattern is set, and is carrying the high-intensity while, increases its cling property.
The accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is side view of the present utility model.
In figure: 1, roller wheel body; 2, connection bump; 3, central shaft hole; 4, keyway; 5, cone shape hole.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 2, a kind of roller, comprise cylindrical roller wheel body 1, one side of described roller wheel body 1 is fixedly connected with columniform connection bump 2, be provided with central shaft hole 3 along its thickness direction on described roller wheel body 1 and described connection bump 2, the thickness of described connection bump 2 is greater than the thickness of described roller wheel body 1, and the outer surface of described roller wheel body 1 is provided with reticulate pattern.Described reticulate pattern is grid-like, and the side of described connection bump 2 also offers the cone shape hole 5 be connected with described central shaft hole 3, and the size of described cone shape hole 5 is greater than the size of described central shaft hole 3.
As shown in Figure 1, on described central shaft hole 3, offer keyway 4, described keyway 4 is rectangle groove, processes more convenient.
Without diagram, the surface of described central shaft hole 3 is provided with wearing layer, increases wear resistance, reduces wear.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
