[0025] In order to enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, and the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of implementation of the present invention.

[0026] Referring to the attached drawings, the utility model adopts the following technical scheme: a new light double-speed chain, comprising a plurality of chain links, wherein the plurality of chain links are hinged through a first chain plate 101, wherein the chain link comprises two first chain plates 101 and an axle pin 5 connected between the two first chain plates 101, wherein the axle pin 5 is provided with a first roller 2 on its outer sleeve, wherein at least one end of the first roller 2 is provided with a second roller 3, wherein the first roller 2 comprises an inner support 201 and an outer support 202, wherein at least one reinforcing rib 203 is provided between the inner support 201 and the outer support 202. The inner support 201 and the outer support 202 are cylindrical structures.

[0027] Through the above technical solution, the above arrangement of the first roller 2 can not only reduce its own weight, but also ensure its strength and extend its service life due to the arrangement of the reinforcing ribs 203.

[0028] There are a plurality of reinforcing ribs 203, and the angles between two adjacent reinforcing ribs 203 are consistent. The inner support member 201, the outer support member 202 and the reinforcing ribs 203 are integrally formed.

[0029] The second roller 3 includes an integrally formed first ring body 301 and a second ring body 302. The diameter of the second ring body 302 is smaller than that of the first ring body 301. The first ring body 301 is disposed close to or in contact with the reinforcing rib 203. The first ring body 301 is provided with an inclined surface 303.

[0030] A sleeve 4 is sleeved between the inner wall of the inner support 201 and the outer wall of the shaft pin 5. The length of the sleeve 4 is consistent with the length of the inner support 201.

[0031] The inner support member 201 is longer than the outer support member 202 .
