Transversely-installed longitudinal sealing plug

Abstract

The invention discloses a transversely-installed longitudinal sealing plug. The sealing plug comprises a plug body, an ejector rod, an inclined block, a sealing structure and a pressing structure, wherein a cross hole is formed in the plug body, the ejector rod is arranged in a longitudinal hole of the cross hole, the sealing structure is arranged at the end, corresponding to a hole needing to beplugged, of the ejector rod, the inclined block is arranged in a transverse hole of the cross hole, one end of the outer side of the inclined block is connected with the pressing structure, and the pressing structure is arranged outside the plug body; the inclined block transversely displaces to push the ejector rod to longitudinally displace; and rhombic quadrilateral grooves are formed in the two sides of a rod body of the ejector rod, and the joint between the inclined block and the ejector rod is of a double-trapezoid structure matched with the rhombic quadrilateral grooves in the two sides of the ejector rod. According to the sealing plug, by transversely installing the longitudinal sealing plug, the sealing problem can be actually solved, the leakage risk caused by the fact that a leakage test pipeline cannot be tested is avoided, and the plugging effect is good.

Description

technical field [0001] The invention belongs to the technical field of mechanical process equipment and relates to a sealing plug, in particular to a horizontally installed longitudinal sealing plug which solves the sealing problem of a hole in a hole (cross hole) or a hole in a cavity in a leak test of a seal. Background technique [0002] In many products that require air tightness test or oil pressure leak test, holes in holes (cross holes) often appear. The holes in the cavity need to be sealed, and the seal needs to be released according to the test process. The conventional plug is a one-way seal. Due to the structure, its working direction is on the same axis as the plugging hole. Therefore, limited by the space structure, the conventional plug has the problem of inconvenient installation, or the tightening mechanism cannot be placed and operated in special cases. Bring great difficulty to leak test. Contents of the invention [0003] In order to solve the above pr...

Problems solved by technology

[0002] In many products that require air tightness test or oil pressure leak test, holes in holes (cross holes) often appear. The holes in the cavity need to be sealed, and the seal needs to be released according to the test process. The conventional plug is a one-way seal. Its working direction is on the same axis as the plugging hole. Therefore, due to the limitation of the space structure, the conventional plug has the problem of inconvenient installation, or the tightening mechanism cannot be placed and operated under special circumstances.
