Description

Technical Field

[0001] The invention belongs to the technical field of tire storage, and in particular relates to a tire storage and transporting device. Background Art

[0002] Tires are circular, ground-engaging, rolling elastic rubber products installed on various vehicles or machinery. They are usually installed on metal rims and can support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. In daily use, manufacturers, dealers, or users often need to store tires. Typically, people stack tires horizontally or vertically on shelves for storage. Horizontal stacking is only suitable for short-term storage due to excessive pressure on the bottom tire. Long-term storage is generally carried out by vertical stacking. Vertical storage can effectively prevent the upper tires from squeezing the lower tires, but it also has shortcomings. Vertically stacked shelves usually place tires on a support frame composed of two flat crossbars. The tires are fixed between the crossbars by gravity, which will cause compression at the contact point between the outer wall of the tire and the shelf. Long-term storage will cause the tires to deform, wear, or even crack. The outer wall of the tire is the part that directly contacts the ground during driving. If it wears, it will affect tire performance, may lead to reduced grip, increased fuel consumption, and even affect driving safety. Therefore, a tire storage device that can reduce tire wear is needed. Summary of the Invention

[0026] The arc plate 1 601 is arranged between the arc plates 302, and the curvature of the arc plate 1 601 matches the curvature of the ring body 1 301.

[0027] When in use, first remove the extension plate 2 105, install the inner support mechanism 2 on the cylindrical gear 103 through the cylindrical gear ring 504, and the operator fixes the cylindrical gear 103 so that it cannot rotate. The cylindrical gear 103 limits the cylindrical gear ring 504. Then, the operator pulls the handle 403, the insertion rod 1 402 slides away from the slot 1 303, and the insertion rod 2 606 slides away from the slot 2 605, thereby adjusting the distance between the outer ring 1 3 and the outer ring 2 4 according to the tire width, so that the inner edge of the tire can be placed on the ring body 1 301. The distance between the support block 603 of the outer expansion mechanism 6 and the ring body 2 401 is adjusted at the same time to adapt to the tire width of different tires. Then, the outer ring 2 4 is rotated by the handle 403, and the outer ring 2 4 drives the outer ring 1 3 to rotate through the insertion rod 1 402. The outer ring 1 3 and the outer ring 2 4 rotate around the inner ring 5. During this process, the hinge point between the arc plate 3 604 and the reserved groove 502 gradually moves toward the support block 603, thereby gradually increasing the angle between the arc plate 3 604 and the arc plate 1 601, so that the arc plate 1 601 moves away from the inner support mechanism 2 The arc plate 1 601 is stretched in the direction of the axis, and at the same time, the arc plate 2 602 is turned together under the limitation of the slot 2 605 and the insertion rod 2 606, until the arc plate 1 601 and the support block 603 at the end of the arc plate 2 602 are in contact with the inner wall of the tire, supporting the tire from the inside. The outward expansion mechanism 6 arranged in the circumferential array can make the inner support more uniform, distribute the pressure between the support point and the tire, reduce wear and deformation, and the elastic buckle 304 and the card hole 503 can be used to initially limit the outer ring 1 3, and then tighten the fixing screw 40 5. The end of the fixing screw 405 is fitted into the side wall of the cylindrical gear ring 504 to fix it. Then the current inner support mechanism 2 is pushed toward the extension plate 102 and the next tire is installed until the tire is installed. After the installation and storage are completed, the extension plate 2 105 is reinstalled. During the storage process, the motor 108 continuously outputs and drives the incomplete gear 109 to rotate slowly, thereby controlling the cylindrical gear 103 to drive the inner support mechanism 2 to rotate slowly, so that the tire rotates. Each support point circulates and distributes the pressure to reduce tire wear.
