Description

Mandrel type casing hanger Technical Field The utility model relates to the technical field of hangers, in particular to a mandrel type casing hanger. Background A hanger is a mechanical device for securing, supporting or connecting long-term components such as pipes, bushings, cables, etc., commonly used in petroleum, natural gas, construction, electrical and industrial piping systems. The prior patent (publication number: CN 219993663U) discloses a mandrel type casing hanger convenient to maintain, which comprises a hanger I and a hanger II, wherein the surfaces of the hanger I and the hanger II are respectively provided with a connecting mechanism, the interiors of the hanger I and the hanger II are respectively provided with a fixing mechanism, the connecting mechanism comprises a fixing frame, and the left side surface and the right side surface of the interior of the fixing frame are fixedly connected with the surface of the hanger II.
