Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Referring to fig. 1-3, a movable ring structure with easy replacement includes a movable ring 200 and a stationary ring 300;
wherein the rotating ring 200 is installed on the rotating ring base 100, the rotating ring base 100 and the rotating ring 200 are both installed on the rotating shaft,
the left end of the rotating ring base 100 is provided with a rotating ring connecting groove 110, the right end face of the rotating ring 200 is provided with a rotating ring connecting ring 210, the rotating ring connecting groove 110 and the rotating ring connecting ring 210 are arranged in a matching manner, namely, the rotating ring connecting ring 210 is inserted into the rotating ring connecting groove 110, wherein the end face of the rotating ring base 100, which is in contact with the rotating ring 200, is also provided with a plurality of concentrically arranged sealing ring mounting grooves 120, the cross section of each sealing ring mounting groove 120 is semicircular, a sealing ring 130 is mounted in each sealing ring mounting groove 120, and the inner wall of the rotating ring base 100 is also provided with a key;
the side wall of the movable ring connecting ring 210 of the movable ring 200 is further provided with a locking groove 220, the cross section of the locking groove 220 is in an inverted right trapezoid shape, the top part of the movable ring connecting groove 110 of the movable ring base 100 is further provided with a threaded hole 150 matched with the locking groove 220, the threaded hole 150 is a countersunk hole, a locking screw 160 is connected to the threaded hole 150 in a threaded manner, the centricity of the threaded hole 150 is intersected with the oblique edge of the right trapezoid cross section of the locking groove 220, and the bottom of the locking screw 160 is abutted to the oblique edge of the right trapezoid cross section of the locking groove 220;
