Description

folding tires

technical field

The utility model relates to a tire, in particular to a tire which can be folded into a small volume and is convenient for storage and transportation.

Background technique

First please refer to Fig. 1, which is a schematic diagram of a conventional tire combined with a rim, wherein the tire 11 is covered with several steel wires 13 by using the bead 12 on both ends of the tire, so when the tire 11 is filled with gas, The bead 12 of the tire 11 can firmly lean against the inside of the rim 14 .

Since the bead 12 of the tire 11 needs to be reinforced by the steel wire 13, it can be made into a fixed ring shape, thereby bearing the gas pressure in the tire 11 and being fastened in the rim 14, so the tire of the existing tire 11 The lip 12 is covered with several steel wires 13 arranged together and located at the center of the bead 12 .

Because the bead 12 of the traditional tire 11 needs to be fastened inside the rim 14 by the steel wire 13 with excellent rigidity, so that the tire 11 is not easily deformed by force. The storage methods can only be stacked one by one from bottom to top, or arranged in a horizontal manner, but because the tire 11 is bulky and occupies a considerable amount of space, those storage methods cause inconvenience to the storage and transportation of the tire 11.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a folding tire which can be folded into a small volume tire which is convenient for storage and transportation.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A folding tire, which is different from traditional tires. The bead at both ends of the tire also includes a plurality of rings, and each ring is composed of a plurality of soft steel wires helically wound, and is wrapped by the bead of the tire. covered, and the diameter of the ring is between 0.5 and 2.0 mm, and the diameter of each soft steel wire is between 0.05 and 0.5 mm.

Due to the adoption of the above-mentioned technical scheme, the folding tire of the present invention can fold the tire into a small volume for storage and storage, and this case is different from the traditional tires that cannot be easily loaded and unloaded. Therefore, the utility model Folding tires can effectively improve storage, handling and transportation costs.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figures 2 and 3, the foldable tire of the present invention uses a ring 30 to be wound and arranged in a spiral manner by a soft steel wire 31, so that the ring 30 has the characteristics of a stable structure, so that the bead 21 is fixed in a ring shape, And can withstand the gas pressure filled in the tire 20, and can be fastened in the rim (the rim is not drawn in Fig. 2 and Fig. 3); Excellent toughness and flexibility allow the tire 20 to be folded into a small volume, so the folded tire 20 is not only convenient for storage and storage, but also has a shape that can be transported by a single vehicle (such as a vehicle, a ship). The highly regular loading and unloading efficiency is much higher than that of the existing non-foldable tire 11 (shown in FIG. 1 ), and the utility model can effectively reduce transportation and storage costs.

FIG. 4 is a schematic diagram of the arrangement of the rings in the bead of the tire. It is formed by two rings 30 arranged mutually and then circled twice (arranged in a rectangular shape), and completely covered by the bead 21 .

FIG. 5 is a schematic view showing the arrangement of the rings in the bead of the tire. It is composed of five rings 30 arranged with each other and circled around one another, and completely covered by the bead 21 .

FIG. 6 is a schematic view showing the arrangement of the rings in the bead of the tire. It is composed of three rings 30 arranged in a triangle and then circled around one circle, and completely covered by the bead 21 .

FIG. 7 is a schematic diagram of the arrangement of the rings in the bead of the tire. It is composed of seven rings 30 that are arranged with each other and circle around the circumference, and are completely covered by the bead 21 .

As shown in Figures 8 and 9, a reinforcing wire 40 can be spirally wound on the outermost side of the ring 30. The reinforcing wire 40 is used to increase the bonding strength of the ring 30, and the diameter of the reinforcing wire 40 is between 0.1 and 1.0 mm, and the reinforcing wire 40 can also be placed in the center of the soft steel wire 31 to increase its strength, wherein the reinforcing wire 40 can be made of cotton yarn or synthetic fiber soft steel wire; in addition, it can be added after the rings 30 are arranged mutually The reinforcing wire 40 is wound.

The ring 30 of the present utility model can also be wound around one circle independently, or can be changed into a spiral shape around several circles; the ring 30 in the embodiment is exemplified by the helical winding of nineteen flexible steel wires 31, and In addition, 2 to 30 soft steel wires 31 can be used, which are spirally wound and knitted into a ring 30, and the diameter of the soft steel wires 31 is between 0.05 and 0.5 mm.
