Abstract

The utility model discloses a kind of gasket seal.The gasket seal includes：Steel ring, its inner circumferential has caulking groove in multiple；And rubber inner ring, its section is rhombus, and the periphery of the rubber inner ring is laid with multiple embedded projections corresponding with the interior caulking groove of the steel ring, the rubber inner ring by it is described it is embedded it is raised with the cooperation of interior caulking groove so as to be embedded in the inner circumferential of the steel ring.The inner ring of the gasket seal reduces rubber volume using the structure that diamond-shaped cross-section and multiple spot are fixed, so as to reduce filling rate and compression ratio, good airproof performance is difficult conquassation, and strong applicability, can be applied to various diesel engines.

Description

Gasket seal

Technical field

The utility model is related to engine assembly field, more particularly to a kind of gasket seal.

Background technology

Gasket seal is widely used on a diesel engine, and each system is required for using gasket seal.The effect of gasket seal Primarily to oil, the gas and water of sealing diesel engine, make these media normally be circulated in diesel engine, it is ensured that Oil, Water, Gas etc. Can play and work, so as to ensure the normal operation of diesel engine.

It is that filling rate and compression ratio are too big due to existing gasket seal conquassation, causes gasket seal often to occur squeezing Dabbing side, conquassation, and then cause sealing position the phenomenons such as permeability, infiltration occur, influence sealing effectiveness.

The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and It is not construed as recognizing or implying in any form that the information structure has been existing well known to persons skilled in the art Technology.

Utility model content

The purpose of this utility model is to provide a kind of simple and reasonable gasket seal, and the inner ring of the gasket seal is adopted The structure fixed with diamond-shaped cross-section and multiple spot reduces rubber volume, so that filling rate and compression ratio are reduced, good airproof performance, and no Easy conquassation, and strong applicability, can be applied to various diesel engines.

To achieve the above object, the utility model provides a kind of gasket seal, and the gasket seal includes：Steel ring, in it Week has caulking groove in multiple；And rubber inner ring, its section is rhombus, and the periphery of the rubber inner ring is laid with multiple with the steel The corresponding embedded projection of interior caulking groove of circle, the rubber inner ring is by described embedded raised described so as to be embedded in the cooperation of interior caulking groove The inner circumferential of steel ring.

Preferably, in above-mentioned technical proposal, multiple interior caulking grooves are along the circumferentially uniform of steel ring inner circumferential, the multiple embedded projection Circumference along the periphery of rubber inner ring is uniform.

Preferably, in above-mentioned technical proposal, multiple interior caulking grooves are rectangular channel, the multiple embedded raised for rectangle is convex Rise.

Preferably, in above-mentioned technical proposal, interior caulking groove is that the embedded projection is along rubber uniform four along the inner circumferential of steel ring Uniform four in the periphery of glue inner ring.

Compared with prior art, the utility model has the advantages that：The inner ring of the gasket seal is cut using rhombus The structure that face and multiple spot are fixed reduces rubber volume, so as to reduce filling rate and compression ratio, good airproof performance is difficult conquassation, And strong applicability, various diesel engines can be applied to.

Brief description of the drawings

Fig. 1 is the structural representation of gasket seal of the present utility model.

Fig. 2 is the cross section structure diagram of gasket seal of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality New protection domain is not limited by specific embodiment.

Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units Part or other parts.

As depicted in figs. 1 and 2, the concrete structure of the gasket seal according to the utility model specific embodiment includes：Steel Circle 1 and the rubber inner ring 2 for being laid in the inner circumferential of steel ring 1, wherein, the section of rubber inner ring 2 is rhombus, and steel is embedded in using multiple spot In circle 1, rubber volume is reduced, with suitable filling rate and compression ratio, good airproof performance is difficult conquassation, and strong applicability, Various diesel engines can be applied to.

Specifically, steel ring 1 is laid in the periphery of the gasket seal as the skeleton of gasket seal.The inner circumferential of the steel ring 1 With caulking groove in multiple, for embedding rubber inner ring.Preferably, multiple interior caulking grooves are along the circumferential uniform of the inner circumferential of steel ring 1.In multiple Caulking groove is rectangular channel.

The section of rubber inner ring 2 is rhombus, and its periphery is laid with multiple corresponding with the interior caulking groove of steel ring 1 embedded raised 3, Rubber inner ring 2 coordinated so as to be embedded in the inner circumferential of steel ring 1 by the embedded raised interior caulking groove with steel ring 1, and rubber inner ring 2 cuts Face is rhombus, reduces rubber volume, and with suitable filling rate and compression ratio, good airproof performance is difficult conquassation, and applicability By force, various diesel engines can be applied to.Preferably, multiple embedded raised peripheries along rubber inner ring 2 is circumferential uniform.In multiple It is embedding raised for rectangular preiection.

Preferably, interior caulking groove is that, uniform four along the inner circumferential of steel ring 1, accordingly, embedded projection is along the outer of rubber inner ring 2 Four of Zhou Junbu.Rubber inner ring 2 is fixed with steel ring 1 by 4 structures, improves the setting-in jail of rubber inner ring 2 and steel ring 1 Solidity.

To sum up, the inner ring of the gasket seal reduces rubber volume using the structure that diamond-shaped cross-section and multiple spot are fixed, from And filling rate and compression ratio are reduced, good airproof performance is difficult conquassation, and strong applicability, can be applied to various diesel engines.

The foregoing description to specific illustrative embodiment of the present utility model be in order to illustrate and illustration purpose.These Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining certain principles of the present utility model And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the present utility model Property embodiment and a variety of selections and change.Scope of the present utility model is intended to by claims and its waits similar shape Formula is limited.
