Skidproof chain

The embodiment of the utility model discloses a skidproof chain. The chain comprises an upper side chain and a lower side chain, wherein a triangle chain mechanism is arranged between the upper side chain and the lower side chain, and the triangle chain mechanism is formed by connecting the heads and the tails of a plurality of triangle chain rings uniformly distributed; twisted chains at two base angle positions of the triangle chain rings are respectively and fixedly connected with the upper side chain and the lower side chain through connecting twisted chains with double hooks; fastening buckles are arranged at one end part of the upper side chain and at one end part of the lower side chain, buckle rings are arranged at positions, which are two to three side chain rings away from the fastening buckles, of side chain rings, and an upper tail chain and a lower tail chain are respectively arranged at the other end part of the upper side chain and at the other end part of the lower side chain. According to the skidproof chain provided by the utility model, the triangle chain mechanism is arranged between the upper side chain and the lower side chain, so that a contact area between a wheel and the ground is reduced, and at the same time, effective contact of the skidproof chain with the ground is promoted, and the skidproof effect of the skidproof chain is improved.
