The invention discloses an anti-freezing well cementing ring. The anti-freezing well cementing ring comprises an outer well ring, an inner well ring and a compression ring, wherein the outer well ring is mounted on an inspection well; the inner well ring is mounted on the outer well ring and provided with a well lid; the compression ring is arranged between the inner well ring and the outer well ring; the outer well ring is of a Z-shaped structure; the inner well ring is mounted on the outer well ring; one side of the outer well ring is provided with a limiting boss; the limiting boss is a slope and inclines towards a well hole; the well lid is connected to the edge of the inner well ring through arc-shaped supports in an overturning mode; eight reinforcing ribs are arrayed at the bottom of the well lid around the center of the well lid. By adopting the anti-freezing well cementing ring, the problem that a well ring freezes in winter is effectively solved.
