Abstract
The utility model discloses an air inlet cushion structure good in sealing property. The air inlet cushion structure comprises a spacer body. The spacer body is provided with two rows of air inlets distributed in a staggered mode, sealing protruding ribs are respectively arranged on the outer edges of the air inlets, and adjusting grooves intersecting with the sealing protruding ribs are respectively formed in the outer edges of the air inlets. The portions, on the inner sides of the sealing protruding ribs, of the air inlets are coated with rubber layers, sealing lip portions are arranged on the inner edges of the rubber layers and provided with glue filling holes, and the portions, on the peripheries of the air inlets, of the glue filling holes are coated with sealing silica gel layers. The spacer body is provided with installing holes and locating holes, and the portions of the installing holes and the locating holes are respectively coated with half-round nylon plastic layers. Round locating bosses are arranged on the diagonal line of the spacer body. The air inlet cushion structure does not deform easily after being stressed for a long time. In the use process of the air inlet cushion structure, air pressure is centralized near the air inlets through the structure of the sealing protruding ribs, the rubber layers and the sealing lip portions. The air inlet cushion structure is simple in structure, easy and convenient to manufacture and easy to produce, and guarantees the production efficiency.
Description
Technical field
The utility model relates to gasket structure technical field, relates in particular to a kind of air inlet mat structure of good seal performance.
Background technique
Air inlet pad is used for guaranteeing the excellent sealing between parts, and prevent that extraneous gas from entering, on motor, it,, between cylinder block and head, guarantees that pressurized gas do not leak, existing air inlet pad is mostly single layer structure, it has been fixed by welding on cylinder body, on the one hand easy stress deformation, and working life is low, second must make air pressure concentrate on suction port, thereby to production, brought difficulty, it is not easy to produce, and manufacturing efficiency is low.
Model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of air inlet mat structure of good seal performance is provided.
The utility model is achieved through the following technical solutions:
A kind of air inlet mat structure of good seal performance, include shim body, in described shim body, be distributed with the suction port that two line misregistrations are arranged, the outer edge of described suction port is respectively equipped with the regulating tank that seal bead and seal bead cross, on the suction port of described seal bead inner side, be coated with rubber layer, the inside edge of described rubber layer is provided with sealed lip, on described sealed lip, be distributed with and fill glue aperture, and at suction port periphery, apply sealed silicon glue-line along filling glue aperture position, in described shim body, be distributed with mounting hole and positioning hole, described mounting hole and positioning hole place are coated with respectively semicircular nylon plastic material layer, in the diagonal positions of described shim body, be also distributed with circular positioning boss.
The utility model has the advantages that:
The utility model is by the structure of the regulating tank that is communicated with suction port, can assist the stressing conditions that alleviates suction port place, after making it for a long time stressed, be not easy distortion, by the structure of seal bead, rubber layer and sealed lip, make its in use air pressure concentrate near suction port, its structure manufacture is simple, convenient, easily produces, and has guaranteed manufacturing efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of air inlet mat structure of good seal performance, include shim body 1, in shim body 1, be distributed with the suction port 2 that two line misregistrations are arranged, the outer edge of suction port 2 is respectively equipped with the regulating tank 4 that seal bead 3 and seal bead 3 cross, on the suction port of seal bead 3 inner sides, be coated with rubber layer 5, the inside edge of rubber layer 5 is provided with sealed lip 6, on sealed lip 6, be distributed with and fill glue aperture 7, and at suction port periphery, apply sealed silicon glue-line 8 along filling glue aperture 7 positions, in shim body 1, be distributed with mounting hole 9 and positioning hole 10, mounting hole 9 and positioning hole 10 places are coated with respectively semicircular nylon plastic material layer 11, in the diagonal positions of shim body 1, be also distributed with circular positioning boss 12.
