[0024] The cord layer 1 is surrounded to form a circumference, the printed layer 2 is arranged on the outer periphery of the cord layer 1, the transparent glass rubber tread layer 3 is arranged on the outer periphery of the printed layer 2, and the surface of the transparent glass rubber tread layer 3 is provided with a pattern, such as Figure 3 and Figure 4 shown.

[0025] Of course, if Figure 1 As shown, it also includes: a wire ring 4, which is arranged on both sides of the inner surface of the cord layer 1 and is used to fix the cord layer 1.

[0026] The transparent glass glue tread with built-in printed colorful children's bicycle tire provided by the embodiment of the utility model is obtained by vulcanizing a tire body of a carcass layer 1, a printed layer 2 and a transparent glass glue tread layer 3, so that the printed layer 2 is located between the carcass layer 1 and the transparent glass glue tread layer 3, which can avoid the occurrence of rapid fading, discoloration and wear due to exposure to sunlight and ozone aging in the air.

[0027] In addition, by setting the tread layer to be transparent, the eyes can observe the printing through the tread layer, ensuring that the printing will not be blocked by the tread layer.

[0028] Hereinafter, the printed layer 2 and the transparent glass glue tread layer 3 will be described separately.

[0029] In one possible implementation, Figure 2 As shown, the printed layer 2 includes: a base color layer 201 and a logo pattern layer 202, wherein the base color layer 201 is closely attached to and covers the periphery of the cord layer 1, and the logo pattern layer 202 is formed on the base color layer by printing; in addition, the base color layer 20 is obtained by rolling a colored rubber material through a two-roll calender.
