[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0014] See attached Figure 1-2 , an assembled rubber seal, including a seal consisting of an outer body 1 and an inner body 2, the inner body 2 is inserted in the outer body 1, and a meshing device is provided between the outer body 1 and the inner body 2, the meshing device includes an inner tooth group 3 opened in the inner ring of the outer body 1, and also includes an outer tooth group 4 opened in the outer ring of the inner body 2, the inner tooth group 3 and the outer tooth group 4 are both composed of a plurality of teeth distributed at equal intervals, and the two cooperate with each other, by providing a meshing device between the outer body 1 and the inner body 2, the inner body 2 is inserted into the outer body 1, so that the outer tooth group 4 and the inner tooth group 3 are meshed, so that the outer body 1 and the inner body 2 can be combined into a seal, and the two are combined by tooth meshing, which greatly improves the reliability of the combination, and is still convenient to replace, so that when the inner ring of the seal is damaged, only the inner body 2 needs to be replaced, which greatly reduces the maintenance cost.

[0015] In the present embodiment, it should be noted that the bottom of the outer body 1 is a lower cover 10, the top of the inner body 2 is an upper cover 9, and the cross-sectional diameters of the two are consistent, which ensures that when the outer body 1 and the inner body 2 are assembled, a three-dimensional cylindrical seal will be formed, which is convenient for installation and use. A first fixing component is provided between the upper cover 9 and the top of the outer body 1, and the first fixing component includes a plurality of equidistantly distributed first fixing holes 7 opened on the top of the outer body 1, and also includes a plurality of equidistantly distributed first fixing columns 8 fixed under the upper cover 9, and the two are consistent in number and mutually adapted, and a second fixing component is provided between the bottom of the inner body 2 and the lower cover 10, and the second fixing component includes a plurality of equidistantly distributed second fixing holes 11 opened on the lower cover 10, and also includes a plurality of equidistantly distributed second fixing columns 12 fixed at the bottom of the inner body 2, and the two are consistent in number and mutually adapted.
