Automotive antiskid device

Abstract

The invention provides an automotive antiskid device which comprises a plurality of antiskid blocks, wherein each antiskid block adopts the structure of an n-shaped framework, the inner side of each n-shaped framework corresponds to the inner side of a tire, the outer side of each n-shaped framework corresponds to the outer side of the tire, a fixing bolt is further arranged outside the outer side of each n-shaped framework, an open type foot piece is arranged below the outer side of each n-shaped framework, the fixing bolts on the outer sides of the multiple antiskid blocks are peripherally connected through connecting pieces, the open type foot pieces are connected with a nut tray towards the center of a circle through screws I, and the antiskid blocks are connected around the tire to form a whole. The n-shaped framework structures of the antiskid blocks are firstly clamped on the outer surface of the tire, then the screws I and the nut tray are used for fixing and tightening the antiskid blocks, and finally the antiskid blocks are further connected into a whole through the connecting pieces. The antiskid device is durable and universal, the tire is not damaged, the structure is simple, and the antiskid device can be mounted or dismounted by one adjustable spanner and one flat head screwdriver or only one adjustable spanner.

Description

technical field [0001] The invention relates to a snow and ice anti-skid device for vehicles. Background technique [0002] At present, the known vehicle snow and ice anti-skid devices are dominated by beef tendon anti-skid chains, rubber anti-skid chains, steel or iron anti-skid chains. However, beef tendon anti-skid chains are easy to break with changes in temperature; the anti-skid steel nails of beef tendon anti-skid chains and rubber anti-skid chains wear out quickly on ice and snow roads and normal dry roads, and the anti-skid performance will be greatly reduced; steel or iron anti-skid chains Chains are easy to damage tires; snow chains are troublesome to install and disassemble, and generally require jacks or support blocks. [0003] Another kind of anti-skid chain is generally only suitable for a certain type of tire and is not universal. Contents of the invention [0004] In order to overcome the shortcomings of the existing anti-skid chains such as poor durabi...
