Utility model content

It is mentioned above in the background art due to work to solve that the utility model provides a kind of novel Air-tight piston ring Plug ring after mounting, due to being provided with opening, reduces, while the hull shape of piston ring becomes so as to cause the air-tightness of piston ring entirety Property, the technical issues of causing piston ring whole with the connection of piston groove loosening more.

To achieve the goals above, the utility model uses following technical scheme: a kind of novel Air-tight piston ring, packet Piston ring body is included, first sliding groove is equipped on the outside of the piston ring body, multiple location holes are equipped on the inside of the first sliding groove, and The piston ring body is equipped with opening, and the opening, the piston ring body both ends are detachably connected the first sealing block.

Preferably, the first sliding groove is located in the middle part of the piston ring body, and multiple location hole interval settings.

Preferably, the arc-shaped setting of the first sealing block, and first sealing block both ends are symmetrically arranged with two first Convex block, the piston ring body both ends are symmetrically arranged with two second sliding slots, and two first convex blocks are slidably connected described second Sliding slot.

Preferably, the first convex block horizontal cross width is less than the piston ring body width, and the second sliding slot Horizontal cross width be less than the piston ring body width, and first convex block be equipped with the first positioning bolt, described first Positioning bolt is detachably connected the piston ring body.

Preferably, two L-shaped settings of the first convex block, and two first convex blocks are set in rotational symmetry It sets, and two first convex block sides are in same level, and the second sliding slot is correspondingly arranged.

Preferably, and on the inside of first sealing block two the first notches, the piston ring body both ends pair are correspondingly provided with It should set there are two the second convex block, corresponding two first notches that are slidably connected of two second convex blocks, and described second convex Block one end is equipped with elastomer block, and elastomer block setting in a rectangular trapezoid, and the long side of the elastomer block is set to outside.

Compared with prior art, the utility model has the beneficial effects that

The utility model is provided with first by being provided with opening in piston ring body, also, on the outside of piston ring body Sliding slot, first sliding groove is interior to be equipped with location hole, the connection of piston ring body and piston groove is carried out using location hole, and installing In first sealing block that is slidably connected after, so that piston ring body is in whole installation, also, by the first sealing block to work Plug ring ontology is limited, i.e., closely, while air-tightness is more preferable.
