Abstract
The utility model belongs to the technical field of insulin needle heads, and particularly relates to a retractable insulin needle head which comprises an insulin needle head body, a rotating block is arranged on the insulin needle head body, a moving groove, a sliding groove and a through hole are formed in the insulin needle head body, and a sleeve and a limiting block are arranged in the insulin needle head body. A sleeve is arranged in the sleeve and connected with the rotating block, a lifting seat is arranged at the inner end of the sleeve, threads on the inner wall of the sleeve are matched with threads on the outer wall of the upper end of the lifting seat, a limiting groove and a needle seat are formed in the lifting seat, a needle tube is arranged on the needle seat, a cover plate is arranged in a moving groove, and the cover plate is movably connected with the moving groove. After the insulin needle head is used, the needle tube can be directly retracted into the insulin needle head body for storage, the recovery difficulty can be reduced, the recovery safety can be improved, and the risk that the needle cap is relatively sleeved with the needle tube when the needle cap is sleeved back to avoid exposure of the needle tube is avoided.
