Hole plugging structure and casing hole plugging structure thereof

Abstract

The invention belongs to the technical field of casing hole plugging design, and particularly relates to a hole plugging structure. The hole plugging structure comprises a mounting cylinder, a plugging pin and a spring, wherein two axial guide grooves, two circumferential guide grooves and a limiting bulge are arranged on the inner wall of the mounting cylinder; one end of each circumferential guide groove is correspondingly communicated with one axial guide groove; and two guide bulges are arranged on the outer wall of the plugging pin. The hole plugging structure has a hole plugging state and a non-hole-plugging state; when the hole plugging structure is in the hole plugging state, each guide bulge is correspondingly clamped in one circumferential guide groove, one end of the plugging pin extends out of the mounting cylinder, one end of the spring abuts against the limiting bulge, and the other end of the spring abuts against one or two guide bulges; and when the hole plugging structure in the non-hole-plugging state, the plugging pin rotates, so that each guide bulge is separated from the corresponding circumferential guide groove, enters the corresponding axial guide groove andmoves along the corresponding axial guide groove under the pushing of the spring, and the end, extending out of the mounting cylinder, of the plugging pin retracts. In addition, the invention relatesto a casing hole plugging structure with the hole plugging structure.

Description

technical field [0001] The application belongs to the technical field of casing hole plugging design, and in particular relates to a hole plugging structure and a casing hole plugging structure thereof. Background technique [0002] In order to facilitate the inspection and maintenance of the compressor parts in the engine, a borescope hole is usually set on the casing. Carry out the borescope inspection. After the inspection is completed, take out the borescope and plug the hole of the borescope on the casing with a plug to ensure engine performance. [0003] The current plug can well block the hole of the borescope on the single-layer casing, effectively ensuring the performance of the engine, but its structure is complicated, disassembly and operation are difficult, and it requires high technical personnel. In addition, there are many There are springs that are difficult to remove and replace if damaged. [0004] In view of the existence of above-mentioned technical def...
