Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not 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.

Referring to fig. 1-7, the present invention provides a technical solution: a combined chain wheel comprises a wheel body 1 and a wheel ring 7, wherein the outer side of the wheel body 1 is provided with the wheel ring 7, the bottom of the wheel ring 7 is fixedly connected with a first fixing plate 3, the bottom of the wheel ring 7 is fixedly connected with a second fixing plate 5, the inside of the first fixing plate 3 is provided with a sliding groove 9 matched with the second fixing plate 5, the sliding groove 9 can enable the first fixing plate 3 to be inserted into the second fixing plate 5, so that the first fixing plate 3 and the second fixing plate 5 are more firmly fixed, the inside of the wheel body 1 is symmetrically provided with slots 8, the slots 8 can be inserted into the first fixing plate 3 and the second fixing plate 5, so that people can conveniently fix the wheel ring 7, the first fixing plate 3 and the second fixing plate 5 are both in sliding connection with the slots 8, the inside of the wheel body 1 is symmetrically provided with a first threaded hole 4, the inside of the first fixing plate 3 is provided with a second threaded hole 11, and the inside of the second fixing plate 5 is provided with a third threaded hole 12, one side threaded connection of wheel body 1 has bolt 10, and bolt 10 can be used for fixing No. one fixed plate 3 and No. two fixed plates 5 and wheel body 1 to make the wheel ring 7 fixed more firmly.
