DESCRIPTION OF THE EMBODIMENTS

[0021] The invention is further described below in detail in combination with drawings and embodiments.

[0022] Embodiment I: as shown in drawings, a skateboard wheel tyre, including an annular cover tyre 1, embedded parts 2 and a first connector 4 for connecting with a hard wheel buckle 3, wherein the first connector 4 is located on the inner side of the annular cover tyre 1, and a cavity is formed therebetween; n second connectors 5 are disposed in the cavity, wherein n is an integer greater than or equal to 1, and each of the second connectors 5 is connected to the annular cover tyre 1 and the first connector 4; the annular cover tyre 1, the first connector 4 and the n second connectors 5 are integrally formed through any one material of rubber, polyurethane (PU), a thermoplastic elastomer (TPE) and thermoplastic polyurethane (TPU); and the embedded parts 2 are embedded into gaps among the annular cover tyre 1, the first connector 4 and the n second connectors 5 to fill the gaps among the annular cover tyre 1, the first connector 4 and the n second connectors 5, and the embedded parts 2 are made from a material which is the same as the annular cover tyre 1 in type but different in color and hardness.

[0023] In the embodiment, the hardness of the embedded parts 2 is higher than that of the annular cover tyre 1.

[0024] Embodiment II: the embodiment is substantially same as the embodiment I, and the difference only lies in that in the embodiment, the hardness of the embedded parts 2 is lower than that of the annular cover tyre 1.

[0025] When the skateboard wheel tyre of the invention is produced, if the tyre and the hard wheel buckle 3 are integrally formed, a liquid material is poured into a die and the material is taken out after being cured. At the time, the hard wheel buckle 3, the annular cover tyre 1, the first connector 4 and the n second connectors 5 are integrally formed to obtain a formed body. Then the integrally formed tyre is mounted on a secondary injection die, the liquid material is poured into the die to fill the gaps in the annular cover tyre 1, the first connector 4 and the n second connectors 5 to form the embedded parts 2 after being cooled, so processing of the skateboard wheel tyre is finished; if the tyre and the hard wheel buckle 3 are of the split structure, the hard wheel buckle 3 is mounted in the die first, then the liquid material is poured into the die, the annular cover tyre 1, the first connector 4 and the n second connectors 5 are integrally formed after the cured material is taken out and are fixedly connected to the hard wheel buckle 3 to obtain a formed body, then the formed body is mounted in the secondary injection die, the liquid material is poured into the die to fill the gaps in the annular cover tyre 1, the first connector 4 and the n second connectors 5 to form the embedded parts 2 after being cooled, so processing of the skateboard wheel tyre is finished.

[0026] In the skateboard wheel tyre of the invention, the annular cover tyre 1, the first connector 4 and the n second connectors 5 are integrally formed, the embedded parts 2 are poured and formed, and the two-time forming materials can be different in color, so that color matching of the skateboard wheel tyre is improved, and the appearance attractiveness is improved. The two-time forming materials are different in hardness, which can consider shock absorption and duration performance both into consideration.
