Anti-skid device for automobile

Abstract

The invention discloses an anti-skid device for an automobile, which comprises an automobile wheel shaft, a telescopic device and an annular component, wherein the height of the annular component is equal to that of an automobile wheel; the annular component is fixed at the peripheral part of the automobile wheel; a plurality of punching holes are formed in the annular component at intervals; the telescopic device is formed by telescopic rods and hydraulic cylinders; the telescopic rods are arranged inside the hydraulic cylinders; the hydraulic cylinders are arranged on the side wall of the automobile wheel taking the automobile wheel shaft as the center; an arc-shaped plate is connected to the top end of each telescopic rod; anti-skid nails regularly arrayed are arranged on each arc-shaped plate, correspond to the punching holes in the annular component, and can stretch out and retract under the adjustment of the hydraulic cylinders. According to the invention, the anti-skid nails can firmly grasp the ground through the annular component, and the friction between the anti-skid nails and the ground is increased; besides, in the unnecessary situation, the anti-skid nails can retract and the normal driving of the automobile wheel is not influenced.
