Safety hub against tire burst

A safety wheel against tire burst, comprising a rim body, wherein the rim body comprises an outer annular surface, a first side surface and a second side surface, wherein the first side surface and the second side surface are oppositely arranged on two sides of the outer annular surface, wherein a through hole for an automobile half shaft to pass through is defined on the second side surface, and a connecting seat adapted to the automobile half shaft is formed on the first side surface;

• the two sides of the outer annular surface are oppositely provided with a first wheel flange and a second wheel flange, wherein a tire mounting seat is formed between the first wheel flange and the second wheel flange, and an anti-detachment collar is provided on the tire mounting seat, wherein the anti-detachment collar is an annular protruding ring arranged along the outer annular surface, wherein the anti-detachment collar is concentric with the outer annular surface, wherein a surface of the anti-detachment collar is provided with a toothed structure which comprises a plurality of protruding teeth and gullets, wherein the protruding teeth and the gullets are alternately arranged, the protruding teeth are protrusions extending outward from the surface of the anti-detachment collar, and the gullets are grooves recessed inward from the surface of the anti-detachment collar, wherein an outside diameter of the protruding teeth is greater than a diameter of a tire bead adapted to be placed in the tire mounting seat, wherein the first wheel flange is located on the first side surface, the second wheel flange is located on the second side surface, and the automobile half shaft is directed through the second side surface and connected with the center of the first side surface;
• the anti-detachment collar is close to the first wheel flange, a first tire bead seat is formed between the anti-detachment collar and the first wheel flange, and a diameter of the first tire bead seat is smaller than a diameter of the surface of the anti-detachment collar;
• a first protruding ring is provided on the outer annular surface of the rim body, wherein the first protruding ring is close to the second wheel flange, and a second tire bead seat is formed between the first protruding ring and the second wheel flange, wherein the first tire bead seat and the second tire bead seat are symmetrically arranged with a centerline of a nominal width of the rim body as a symmetry axis, wherein a diameter of the first tire bead seat is equal to a diameter of the second tire bead seat;
• and
• a rim outer grooved surface is formed between the first protruding ring and the anti-detachment collar, wherein the protruding teeth are arranged on a side, close to the rim outer grooved surface, of the anti-detachment collar, wherein each gullet is a groove with one open end, and the open end of the gullet faces towards the rim outer grooved surface;
• an inner diameter of the bottom of the gullets is smaller than the diameter of the first tire bead seat;
• and
• the plurality of protruding teeth and the gullets are uniformly arranged on the surface of the anti-detachment collar.
