Sealing ring structure with high applicability

The invention discloses a sealing ring structure with high applicability. The sealing ring structure with the high applicability comprises a shaft member (1), a first half ring body (2), a second halfring body (3), a third half ring body (4) and an outer sleeve ring (5), wherein the first half ring body (2), the second half ring body (3) and the third half ring body (4) are joined with each otherto form a complete sealing ring body, limit devices are arranged at the junctions of the first half ring body (2), the second half ring body (3) and the third half ring body (4), and in a one-way rotation state of the shaft member (1), the limit devices perform axial limit and radial limit on two of the adjacent first half ring body (2), the second half ring body (3), and the third half ring body(4) separately. The sealing ring structure has good assembling property and is suitable for the situation that axially inserting is not easy. 本发明公开了一种适用性强的密封圈结构，包括轴件(1)、第一半圈体(2)、第二半圈体(3)、第三半圈体(4)及外套圈(5)，所述第一半圈体(2)、第二半圈体(3)及第三半
