Abstract

The utility model provides a roller, by the direct nestification of cover tire constitute on the wheel core, the wheel core surface is the gear face, the internal surface of cover tire inner circle be with wheel core surface complex gear face. The inner side of the roller cover tire is provided with a buckle, and the roller core is provided with an arc-shaped hole groove corresponding to the bayonet. The gear surfaces are respectively arranged on the periphery of the wheel core of the roller and the inner side of the outer tire, and the wheel core is tightly matched with the outer tire through the nesting of the gears, so that the problem that the wheel core and the outer tire easily slide relatively is solved, and the use efficiency of the roller is improved.

Description

A kind of roller

Technical field

The utility model relates to a kind of roller, is specifically related to a kind of roller of slip-skid prevention better performances.

Background technology

Early stage roller core wheel periphery of using is smooth surface, and the cover tire inboard also is a smooth surface, and core wheel and cover tire are nestedly captiveed joint by direct, and friction force is less between cover tire and the core wheel, and slide relative easily takes place.

The utility model content

The technical problems to be solved in the utility model provides a kind of antiskid capability roller preferably.

For solving the problems of the technologies described above, a kind of roller of the present utility model directly is nested on the core wheel by cover tire to be formed, and its innovative point is: the described core outer surface of taking turns is a face of gear, and the inside face of cover tire inner ring is the face of gear that cooperates with the wheel core outer surface.

Also be provided with buckle around the described roller cover tire inboard.

Be provided with the arc hole slot with the bayonet socket opposite position on the described roller core wheel.

The advantage of above structure is: described core wheel periphery and cover tire inboard are provided with face of gear respectively, and core wheel closely cooperates by gear is nested with cover tire, have solved the problem that slide relative easily takes place between core wheel and the cover tire, have improved the service efficiency of roller.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model cover tire.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described

As shown in Figure 1, 2, the outside is provided with face of gear 2 on the core wheel 1, cover tire 3 inboards are mate gear face 4, have arc hole slot 5 around between described core wheel 1 and the face of gear 2, the cover tire 3 inboard buckles 6 that also are provided with all around, when cover tire 3 cooperates with core wheel 1, cover tire 3 inboard buckles 6 just insert around the core wheel 1 in the set arc hole slot 5, embed gradually in the hole slot 5 by the buckle 6 of exerting pressure, described core wheel 1 face of gear 2 is in contact with one another with cover tire 3 internal tooth wheel faces 4, mutually nested by pushing gear face 2 with mate gear face 4, captive joint.

Claims (3)

1, a kind of roller directly is nested on the core wheel by cover tire and forms, and it is characterized in that: the described core outer surface of taking turns is a face of gear, the face of gear that the inside face of cover tire inner ring is and the wheel core outer surface cooperates.

2, a kind of roller according to claim 1 is characterized in that: also be provided with buckle around the described roller cover tire inboard.

3, a kind of roller according to claim 1 is characterized in that: be provided with the arc hole slot with the bayonet socket opposite position on the described roller core wheel.
