The present invention relates to a non-fixed tire wearing hole having a snow chain function, and more particularly, to be firmly fixed by simply inserting and tightening from the outer ring side of the tire so that anyone can be easily mounted on the tire without a separate tool. And it relates to a non-fixed tire wearing mouth having a snow chain function that can greatly reduce the wearing time.

In general, a conventional snow chain that increases the frictional force of a tire to easily drive a snow road or an ice road has a ring-type friction straps that cross the outer circumferential surface of the tire, and a ring is attached to the tire inner ring side to fix the friction straps. The inner ring fixing ring (chain or spring) to be formed and fastened and the outer ring fixing ring (chain or spring) to form a ring is fastened to the outer ring side of the tire.

Accordingly, the user first releases the inner ring fixing ring and the outer ring fixing ring which are unhooked to the ground in the direction of the tire, and the friction straps connecting them, and then boards the car again to move the car for a predetermined distance. The snow chain was fixed to the tire in a very cumbersome way by getting out of the car and putting the hand deeply in the tire inner ring direction to fix the inner ring fixing ring first and then fix the outer ring fixing ring.

In addition, a snow chain has been developed to improve the structure of the inner ring fixing ring and the outer ring fixing ring so that the chain can be fixed while the vehicle is not moving. Nevertheless, the inner ring fixing ring is inserted deep into the inner ring side of the tire. Similarly, it has to be fixed, and the work is very cumbersome, and there are many problems such as discarding the arm sleeves by foreign matters on the tires.

In order to solve this conventional inconvenience, a fully fixed tire assembly has been developed which functions as a snow chain and at the same time removes the wheel cover of the car and is directly fixed to the outer ring of the car by bolts.

However, such a fully fixed tire assembly must always run in an assembled state in preparation for snow or ice even when not driving on snow or ice, and suddenly heavy snow falls because a separate tool such as a wrench or spanner is required. It was difficult to prepare for the case of meeting with the road or the ice, and it was difficult for the elderly and women to easily attach and detach the fixed work to fix it to the car's outer ring when it was detached. There was a problem that was difficult to store and carry.

In addition, the conventional snow chain or fully fixed tire assembly has a problem that could not be universally applied to tires of various sizes.

An object of the present invention for solving the above problems is not fixed to any of the fasteners on the outer ring of the vehicle, but firmly fixed only by the gripping force of the finger by tightening the nut member to the car tire without moving the car. The present invention provides a non-fixed tire wear opening having a snow chain function that can be easily attached and detached by only inserting and tightening or releasing the nut member.

In addition, another object of the present invention, because it is a finger foldable, it is possible to greatly reduce the volume during storage / portable, can be applied to a variety of tires of various sizes, do not loosen while driving the car, to prevent theft The present invention provides a non-fixed tire wearing device having a snow chain function.
