Description

heavy-duty bicycle tire

technical field

The invention relates to a bicycle tire, in particular to a heavy-duty bicycle tire.

Background technique

At present, when commercially available bicycles are loaded, the tires are not rigid enough to withstand the pressure generated by the excessive weight, causing them to burst from the center overlap; Wheel hub friction causes tires to burn, etc., because the limited ability of the heavy-duty tires produced by the prior art to resist external forces leads to a high tire damage rate, and the replacement of tires increases the cost of use.

Contents of the invention

The technical problem to be solved by the invention is to provide a heavy-duty bicycle tire with strong resistance to external force.

In order to achieve the above object, the technical scheme adopted by the present invention is: provided

A heavy-duty bicycle tire, including a tire body, the tire body is composed of a high-density layer, a reinforcement layer and a tread layer in sequence from the inside to the outside, and the high-density layer and the reinforcement layer are sequentially surrounded to form a circle, the The reinforcement layer is placed on the periphery of the high-density layer, and the tread layer is placed on the periphery of the reinforcement layer. The tread layer is a 68SA rubber layer with a thickness increased by 5mm and patterns on its surface.

The surface of the preferred tread layer is symmetrically provided with multiple groups of block patterns, each group of block patterns is composed of four ribs and six polygonal pattern blocks.

Preferably, grooves are formed between adjacent polygonal blocks.

A preferred reinforcing layer is a nylon interlaced ply.

The preferred high density layers are folded and overlapped in the center.

Adopting the technical scheme of the present invention, the tread layer is a 68SA rubber material layer, and the thickness is increased by 5 mm, which avoids foreign matter on the road surface such as glass and sharp stone flakes from being pierced; the tire reinforcement layer uses nylon interwoven cord yarn to cover the entire tire , not only disperses the weight and pressure of the tire body, but also enhances the anti-puncture ability of the bicycle tire tread layer, avoids the friction and burnt edge of the bead lip, and enhances the ability of the tire to resist external forces; the tire tread layer is equipped with block pattern blocks, It has good anti-slip effect in rainy days, and also increases the aesthetic feeling of its appearance.

Description of drawings

The following is a brief description of the content expressed in the drawings of this manual and the marks in the drawings:

Fig. 1 is a sectional view of a heavy-duty bicycle tire of the present invention;

Fig. 2 is a partial schematic view of the tread layer of a bicycle heavy-duty tire shown in Fig. 1 according to the present invention.

The marks in the figure are: 1. tread layer; 2. reinforcement layer; 3. high-density layer; 4. strip-shaped rib; 5. polygonal pattern block; 6. groove.

Detailed ways

Referring to the accompanying drawings, through the description of the embodiments, the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the function and working principle of each part, and the manufacturing process And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

Example 1

Fig. 1 is a sectional view of a heavy-duty bicycle tire of the present invention; as shown in the figure, a heavy-duty bicycle tire of the present invention includes a tire body, and the tire body is sequentially composed of a high-density layer 3, a reinforcing layer 2 and a tread layer from the inside to the outside 1 composition, the high-density layer 3 and the reinforcement layer 2 encircle in turn to form a circle, the reinforcement layer 2 is placed on the outer periphery of the high-density layer 3, the tread 1 is placed on the outer periphery of the reinforcement layer 2, and the tread layer 1 is 68SA glue The thickness of the material layer is increased by 5mm; the reinforcement layer 2 is a nylon interwoven cord layer; the high-density layer 3 is folded and overlapped at the center; the technical scheme of the present invention is adopted, the tread layer 1 is a 68SA rubber layer, and the thickness is increased by 5mm, avoiding Foreign matter on the road surface such as glass and sharp stone flakes will puncture it; the tire reinforcement layer 2 uses nylon interwoven curtain yarn to cover the entire tire, which not only disperses the weight pressure on the tire body, but also enhances the puncture resistance of the bicycle tire tread layer 1 Ability to avoid the friction and burnt edge of the bead lip, and enhance the tire's ability to resist external forces;

Example 2

Fig. 2 is a partial schematic view of the tread layer of a heavy-duty bicycle tire of the present invention shown in Fig. 1. The surface of the tread layer 1 of the tire body is symmetrically provided with multiple groups of block patterns, and each group of block patterns is composed of four strip-shaped ribs. 4 and six polygonal pattern blocks 5; grooves 6 are formed between adjacent polygonal pattern blocks 5. The tire tread layer 1 is provided with polygonal pattern blocks 5, which has a good anti-slip effect in rainy days and also increases the aesthetic feeling of its appearance.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods, as long as various insubstantial improvements are adopted in the method concept and technical solutions of the present invention, or there is no improvement Directly applying the conception and technical solutions of the present invention to other occasions falls within the protection scope of the present invention.
