Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

Referring to fig. 1-3, a stand wear and tear retaining ring, including base ring 1, ring channel 2 has been seted up at the top of base ring 1, the inner wall of ring channel 2 is fixed with collar 3, installing port 4 has been seted up at the top of collar 3, the internal rotation of installing port 4 installs roller bearing 5, the top of collar 3 is equipped with go-between 6, the top of go-between 6 is fixed with external ring 7, the department side of external ring 7 passes through stop gear 8 and ring channel 2's inner wall swing joint.

Wherein, installing port 4 is the rectangle mouth, the installation of the roller bearing 5 of being convenient for, and the quantity of installing port 4 is a plurality of, and a plurality of installing port 4 distributes at the even equidistance in the 3 tops of collar for 3 each positions homoenergetic of collar are distributed to roller bearing 5, thereby the atress is balanced.

Wherein, the border of external ring 7 is along with base ring 1 looks parallel and level, and the top of external ring 7 is evenly fixed with a plurality of antiskid ribbed tile 12, can remain stable when being convenient for external contact and external ring 7 contact.

Wherein, stop gear 8 is including seting up the spacing annular 9 in the external ring 7 outside, and the inside activity joint of spacing annular 9 has spacing ring 10, and spacing ring 10 is fixed mutually with the inner wall of ring channel 2 to play the connecting action between base ring 1 and the external ring 7, prevent that separation from appearing in base ring 1 and external ring 7.
