Description

Rubber wheel

Technical Field

The utility model relates to the technical field of rubber wheels.

Background

Rubber wheels are widely used in various industries. The existing rubber wheel consists of a wheel core and an outer cladding rubber tyre, wherein the wheel core is tightly combined through a high-temperature vulcanization process of the rubber tyre, or the joint of the rubber tread and the wheel core is bonded by using glue. However, the combination mode of the high-temperature vulcanization process has the defects of complex production process and lower efficiency; after aging, the glue is used for bonding, so that the situation of degumming easily occurs, and the outer cladding rubber tire and the wheel core are loosened.

Although the utility model patent with the publication number of CN110901292A in the prior art discloses a rubber wheel for a handcart, the rubber wheel comprises a rubber wheel body, the rubber wheel body comprises a rubber outer ring and a wheel hub, the rubber outer ring is wrapped on the outer side of the wheel hub, the inner hollow of the rubber outer ring is annular, the inner hollow is provided with an elastic rod, the outer circumferential end surface of the wheel hub is provided with a groove, a stud is arranged in the groove, the stud is contacted with the rubber outer ring, and the surface of the groove contacted with the rubber outer ring is provided with a layer of adhesive layer. Although the hub and the rubber outer ring of the prior art are not easy to separate and separate through the anti-skid nails and the adhesive layer, the prior art still has the defect of lower production efficiency, the prior art still needs to be adhered by using the adhesive layer, and the adhesive surface needs to be polished and leveled for better adhesion.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a reliable rubber wheel with high production efficiency.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a rubber wheel, includes the wheel core to and the rubber circle of cladding in the outer lane of wheel core, the rubber circle combines together with the wheel core through the hasp structure.

Further, the locking structure comprises a T-shaped clamping groove arranged on the outer ring of the wheel core and a T-shaped buckle arranged on the inner ring of the rubber ring, the clamping groove is matched with the buckle in shape, and the buckle is locked in the clamping groove.

Further, a plurality of notches are formed in the circumferential direction of the buckle, and a plurality of notch arrays are arranged at intervals.

Further, the bottom surface of the clamping groove is an arc-shaped surface with a raised middle part.

Further, the edges of the two sides of the outer ring of the wheel core are higher than the middle part.

Further, the wheel core is in interference fit with the rubber ring.

The beneficial effects of the utility model are as follows: the wheel core and the rubber ring are directly locked together through the locking structure. Compared with the prior art, the process steps of using glue and polishing to clean the bonding surface are omitted, and the process steps of wrapping the wheel core by rubber and vulcanizing at high temperature are not needed. The utility model has firm combination, simple production process and high efficiency, reduces the production cost and avoids the condition of glue degumming. And the thickness of the middle part of the rubber ring is thicker, the elasticity is better and the grabbing force is stronger by arranging the arc-shaped surface. And the circular arc angle is arranged to play a certain limiting role on the rubber ring, so that the rubber ring is limited to transversely shift.

Detailed Description

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1, a rubber wheel includes a wheel core 1, and a rubber ring 2 coated on an outer ring of the wheel core 1. In this embodiment, the wheel core 1 and the rubber ring 2 may be manufactured separately and formed separately. The rubber ring 2 is then combined with the wheel core 1 through a locking structure. In this embodiment, the wheel core 1 and the rubber ring 2 are directly locked together through a locking structure. Compared with the prior art, the process of using glue and polishing to clean the bonding surface is omitted, and the process steps of wrapping the wheel core 1 by rubber and vulcanizing at high temperature are not needed. The embodiment has firm combination, simple production process and high efficiency, reduces the production cost and avoids the condition of glue degumming.

Further, the locking structure comprises a T-shaped clamping groove 3 arranged on the outer ring of the wheel core 1, and a T-shaped buckle 4 arranged on the inner ring of the rubber ring 2. The clamping groove 3 is matched with the buckle 4 in shape, and the buckle 4 is locked in the clamping groove 3. The T-shaped clamping groove 3 and the clamping buckle 4 can limit the displacement and the separation of the rubber ring 2 from the longitudinal direction and the transverse direction. The structure of the embodiment is more reliable and the combination is more compact.

Further, a plurality of notches 7 are arranged in the circumferential direction of the buckle 4, and a plurality of notches 7 are arranged at intervals in an array. The notch 7 is arranged in the embodiment, so that materials can be saved, manufacturing cost can be reduced, and circumferential sliding of the rubber ring 2 and the wheel core 1 can be prevented.

Further, the bottom surface of the clamping groove 3 is an arc-shaped surface 5 with a raised middle part. By the design, the middle part of the rubber ring 2 can be thicker, the elasticity is better, and the grabbing force is stronger.

Further, the edges of the two sides of the outer ring of the wheel core 1 are higher than the middle part. Specifically, the two side edges of the outer ring of the wheel core 1 are provided with outward arc angles 6. The circular arc angle 6 can play a certain limiting role on the rubber ring 2, and limit the rubber ring 2 to transversely shift.

Further, the wheel core 1 and the rubber ring 2 are in interference fit. In particular, the rubber ring 2 is arranged larger at the assembly point of the wheel core 1. The rubber ring 2 and the wheel core 1 are tightly locked together, so that looseness between the rubber ring 2 and the wheel core 1 in the embodiment can not occur.

The above embodiments do not limit the protection scope of the utility model, and those skilled in the art can make equivalent modifications and variations without departing from the whole inventive concept, and they still fall within the scope of the utility model.
