CN203548882U - W-shaped exhaust pad structure - Google Patents

Abstract

The utility model discloses a W-shaped exhaust pad structure, which comprises a gasket body, wherein exhaust openings distributed in a W shape are respectively formed in the gasket body, outwards projected arc-shaped sealing convex ribs are respectively arranged at the exhaust opening part, in addition, kidney-shaped positioning holes are formed between the two rows of air holes positioned at the bottom end of the W shape, regulating holes are formed at the upper part of the kidney-shaped positioning holes, buffer convex ribs opposite to the positions of the arc-shaped sealing convex ribs are arranged at the regulating hole parts, the outer edges of the buffer convex ribs are intersected with the arc-shaped sealing convex ribs, and installing holes are also distributed in the gasket body. The W-shaped exhaust pad structure has the advantages that the gasket body is designed into the W shape matched with the distribution of the exhaust opening according to requirements, the appearance structure of the traditional gasket is changed, the stress surface of the gasket is reduced, through the matching with the structures of the sealing convex ribs at the exhaust opening parts and the buffer convex ribs in opposite positions at the regulating hole parts, a certain elasticity is realized, the W-shaped exhaust pad structure can be fast recovered after receiving the force and cannot be easily damaged after being used for a long time, the service life is long, the use cost is reduced, and the use requirements are met.

Description

A kind of W shape exhaust cushion structure

Technical field

The utility model relates to gasket structure technical field, relates in particular to a kind of W shape exhaust cushion structure.

Background technique

Vent pads is used for guaranteeing the excellent sealing between parts, and prevent that extraneous gas from entering, existing exhaust cushion structure is simple, its body mostly adopts rectangle structure, according to the position of relief opening, then on its position, have corresponding relief opening, remove relief opening position, remaining body structure is not removed, and will in the middle of invisible, increase the stress surface of pad, affect its elasticity, when it is subject to after atmospheric pressure for a long time, be difficult to recover, thereby reduced its working life, need often to change, increased user cost.

Model utility content

The purpose of this utility model is the deficiency in order to make up prior art, and a kind of W shape exhaust cushion structure is provided.

The utility model is achieved through the following technical solutions:

A kind of W shape exhaust cushion structure, include shim body, in described shim body, there is into respectively the relief opening that W shape distributes, described exhaust ports is respectively equipped with outwards outstanding arc seal bead, and wherein between two exhaust ports of W shape bottom, be provided with kidney-shaped positioning hole, the top of described kidney-shaped positioning hole is provided with adjustment hole, described adjustment hole place is provided with the buffering convex tendon with arc seal bead position opposite, the outward edge of described buffering convex tendon and arc seal bead intersect, and are also distributed with mounting hole in described shim body.

The utility model has the advantages that:

The utility model is designed to shim body and the relief opening W shape coordinating that distributes as required, changed traditional pad form structure, reduced the stress surface of pad, the structure that coordinates the buffering convex tendon of exhaust ports seal bead and adjustment hole place position opposite, makes it have certain elasticity, is subject to can recovering very soon after power, after long-term use, be not easy to damage, long service life, has reduced user cost, has met usage requirement.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Embodiment

Referring to accompanying drawing, a kind of W shape exhaust cushion structure, include shim body 1, in shim body 1, there is into respectively the relief opening 2 that W shape distributes, relief opening 2 places are respectively equipped with outwards outstanding arc seal bead 3, and wherein between two exhaust ports of W shape bottom, be provided with kidney-shaped positioning hole 4, the top of kidney-shaped positioning hole 4 is provided with adjustment hole 5, adjustment hole 5 places are provided with the buffering convex tendon 6 with arc seal bead 3 position opposite, outward edge and the arc seal bead 3 of buffering convex tendon 6 intersect, and are also distributed with mounting hole 7 in shim body 1.

Claims (1)

1. a W shape exhaust cushion structure, include shim body, it is characterized in that: in described shim body, have into respectively the relief opening that W shape distributes, described exhaust ports is respectively equipped with outwards outstanding arc seal bead, and wherein between two exhaust ports of W shape bottom, be provided with kidney-shaped positioning hole, the top of described kidney-shaped positioning hole is provided with adjustment hole, described adjustment hole place is provided with the buffering convex tendon with arc seal bead position opposite, the outward edge of described buffering convex tendon and arc seal bead intersect, and are also distributed with mounting hole in described shim body.
