Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1-7, the integrated multi-cavity frame tube includes a straight tube 1, an upper bent tube 2 and a lower bent tube 3, the two ends of the straight tube 1 are respectively and integrally provided with the upper bent tube 2 and the lower bent tube 3, the lower end of the inside of the straight tube 1 is provided with a first cavity 4, and the upper end of the inside of the straight tube 1 is provided with a plurality of second cavities 5.

When specifically setting up, integrated into one piece multicavity structure bicycle frame pipe is still including supplementary stop gear 6, and supplementary stop gear 6 locates one side about No. two cavity 5's both ends respectively, and supplementary stop gear 6 is including a limiting plate 601 and No. two limiting plates 602. Carry out spacing fixed to the inside circuit of No. two cavitys 5 through limiting plate 601 and No. two limiting plates 602 to avoid producing the circuit and produce the condition such as winding in the inside of No. two cavitys 5, the later stage of being convenient for more overhauls the condition such as circuit, more convenient.
