Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in attached figures 2-4, the self-locking damping block is used for connecting a shaft rod 6 and comprises an outer ring 1, a metal ring 2 and an inner ring 3, wherein the outer ring 1 and the inner ring 3 are made of rubber materials. The outer ring 1 is coated on the periphery of the metal ring 2, the inner ring 3 is arranged in the inner cavity of the outer ring 1, and the outer wall of the inner ring 3 extends towards the inner wall of the outer ring 1 to form a first reinforcing rib 4 and a second reinforcing rib 5; the first reinforcing ribs 4 are uniformly distributed along the circumference of the left side of the axis L of the inner ring 3, the second reinforcing ribs 5 are uniformly distributed along the circumference of the right side of the axis L of the inner ring 3, and the first reinforcing ribs 4 and the second reinforcing ribs 5 are arranged in a staggered manner; the shaft lever 6 is connected with the inner wall of the inner ring 3 in an interference fit manner, the inner diameter of the inner ring 3 is 22.5 +/-0.3 mm, and the diameter of the shaft lever 6 is 27 +/-0.15 mm.

As shown in fig. 2, the number of the first reinforcing ribs 4 is three (three in the present embodiment, or other numbers), and an angle formed between adjacent first reinforcing ribs 4 is 120 °; the number of the second reinforcing ribs 5 is three (three in the present embodiment, and other numbers are also possible), and the angle formed between adjacent second reinforcing ribs 5 is 120 °. The angle formed between adjacent first 4 and second 5 reinforcing ribs is 60 °. Preferably, the width of the first reinforcing rib 4 and the length of the second reinforcing rib 5 are both 4 +/-1 mm, and the length of the first reinforcing rib 4 and the length of the second reinforcing rib 5 are both 15 +/-1 mm.
