At this time, the two non-slip arms 400 coupled to the rotating discs 330a and 330b of the plurality of non-slip arms 400 are positioned to be in contact with the road surface, and are coupled to the tire T by opening them to both sides. do.

Next, after fitting the locking plate 500 on the outside of the support plate 300 by rotating the locking plate 500 clockwise or counterclockwise to bind to the fixed plate 200, the mounting is completed quickly and easily. Done.

Although a preferred embodiment of the anti-skid device for mounting a tire according to the present invention has been described above, the present invention is not limited thereto, and various modifications are made within the scope of the claims and the detailed description of the invention and the accompanying drawings. It is possible to implement and this also belongs to the present invention.

According to the tire anti-skid device of the present invention as described above, first, in the anti-skid device mounted on the tire in order to safely drive the snow road or the ice road, the installation is easy, tires of various sizes It can be widely used in the road conditions of various conditions, there is an advantage to ensure a stable driving performance.

Second, in the case of attaching the anti-slip arm to the support plate, by designing a plurality of fitting adjusting holes, by selecting the fitting adjusting hole according to the size of the tire and attaching the anti-slip arm, the flexibility to easily and appropriately fit various tires There is an advantage that can be provided.

Third, by forming inclined surfaces at both edges of the contact portion of the non-slip arm and forming reinforcing ribs at various angles on the outer surface of the contact portion, the overall strength of the contact portion can be reinforced and the contact force with the eye can be increased as much as possible. There is this.

Fourth, by mounting a plurality of spikes arranged in a zigzag form in the contact portion of the anti-slip arm, there is an advantage that can maximize the braking force by increasing the area of the scratch on the ice road.

Fifth, by combining the anti-slip arm by forming only the fitting adjustment hole without the rotating disc on the other mating plate other than the pair of the engaging plate protruding from the support plate, it is effective to prevent the anti-slip arm from twisting on the tire when driving on snow road or ice road There is an advantage that can be prevented.

Sixth, by forming a hole having a certain size penetrating the contact portion on one side of the contact portion of the non-slip arm, and by forming a 'U' shaped groove at the end of the contact portion, further improve the grounding force on the snow-covered road surface There is an advantage to this.
