Abstract

The utility model discloses an antiskid device. A disc (Figure 1-5) of which the inner side is provided with 6-8 dovetail-groove slide ways is adopted, the inner sides of the slide ways are used for placing 6-8 sickle-shaped claws (Figure 1-1) of the antiskid device, each claw and a claw slide bar handle (Figure 1-2) are hinged through a through pin (Figure 1-3), can move inwards and can be supported outwards to keep the shapes thereof unchanged, the end part of the claw slide bar handle (Figure 1-2) is provided with a triangular centripetal component with a slope, and the claw slide bar handles (Figure 1-2) are placed in the dovetail-groove slide ways of the dovetail-groove disc (Figure 1-5). When in use, the antiskid device is squeezed downwards through a fastening bolt (Figure 1-9); through oppositely squeezing and sliding a pressure disc (Figure 1-7) of which the upper part is provided with 6-8 inner slide ways and the triangular components at the end parts of the claw slide bar handles (Figure 1-2) at a ramp angle of over 45 DEG, the 6-8 sickle-shaped claws (Figure 1-1) are forced to simultaneously move transversely in parallel to the center of the dovetail-groove disc (Figure 1-5), so that the outer diameter of the antiskid device is gradually reduced; with the gradual screwing of the fastening bolt (Figure 1-9), antiskid sharp-beak teeth (Figure 1-4) of the claws are tightly fastened on a tire; by using sharp-beaks and the teeth to be in contact with the ground, the friction force and the traction force are increased. A currently known existing automotive antiskid device is implemented in a manner that iron hoops are mutually connected to form an iron chain, and after being restructured, the iron chain is bonded on an automotive tire to achieve an antiskid purpose. Therefore, the antiskid device effectively solves the problem that traditional automotive antiskid chains are inconvenient to install, easy to fall off, and poor in antiskid effect.
