Abstract

The utility model discloses a rotating mechanism applicable to while-drilling coring and belongs to the field of design and manufacture technology of well drilling coring tools. The rotating mechanism comprises a bearing box, a mandrel and an adjusting cap. The upper end of the mandrel is fixed in the bearing box through a bearing. The lower end of the mandrel is arranged in the adjusting cap and is connected with the adjusting cap through threads. A single-current valve seat, a plum blossom baffle and a brake ring are arranged at the lower end of the mandrel in the adjusting cap. The brake ring is fixed by a press cap. A steel ball is arranged on the single-current valve seat. The adjusting cap is connected with an elastic clamping mechanism. The rotating mechanism can realize independent rotation of an inner barrel at coring time. When an outer barrel is driven by a rotating disk to rotate, due to the fact that a rotation assembly enables the inner barrel to rotate independently at coring time, the coring inner barrel can not rotate along the outer barrel. Consequently, rock cores can enter conveniently.
