Abstract
The invention relates to the technical field of engine parts, in particular to a sealing gasket of a plastic intake manifold of an engine. The sealing gasket comprises a body, wherein the upper end and the lower end of the body are respectively provided with a flange, the body and the flanges are connected in a split mode, a supporting ring is arranged between the body and each flange, clamping rails are arranged at the upper ends and the lower ends of the supporting rings, the section of each clamping rail is of a T shape or a cross shape, the inner wall of each flange and the outer wall of the body are both provided with clamping grooves which are connected with the clamping rails in a matched mode, and the supporting rings are connected with the body and the flanges in a clamped mode. According to the sealing gasket, since the supporting rings with the clamping rails are arranged between the body and the flanges, the body and the flanges can be connected detachably; when the flanges or the body is squeezed and damaged, replacement is convenient, and therefore the service life can be prolonged while the sealing effect is guaranteed.
Description
Technical field
The present invention relates to engine component technical field, especially relate to a kind of sealing gasket of plastics air inlet manifold branch of engine.
Background technique
When ring structure between designed engines plastic air intake manifold and closure, prior art is by orthogonal seal ring Cross section Design, but in fact because plastics tracheae itself exists micro-strain, nut inserts also has the variation of height tolerance, this rectangular seal Cross section Design lost efficacy sometimes, cause gas leakage, the Sealing of existing a kind of plastics air inlet manifold branch of engine, it is to be provided with flange on the basis of original Sealing, although can play the effect that prevents gas leakage, but because flange and Sealing are integrated, therefore can increase stress surface in the time of overall pressurized, but this stressed be not equally distributed, so easily there is local deformation, even squeezed situation of damaging by pressure, necessary integral replacing when can affecting working life and damaging, can cause waste.
Summary of the invention
For the deficiency of above-mentioned prior art existence, the object of this invention is to provide a kind of sealing gasket of plastics air inlet manifold branch of engine, it has sealing effect, and it is convenient to change, the feature of long service life.
To achieve these goals, the technical solution adopted in the present invention is: a kind of sealing gasket of plastics air inlet manifold branch of engine, comprise body, body upper/lower terminal is equipped with flange, described body is connected with flange split, between body and flange, is provided with support ring, and support ring upper/lower terminal is provided with the card rail of cross section one-tenth " T " font or " ten " font, flange inner wall and body outer wall all offer and the draw-in groove that blocks rail and be connected, clamping between described support ring and body and flange.
Wherein, the both sides of described body are provided with flange, and described inner body wall offers the chute that can make support ring slide, and the cross section of described flange is triangle or semicircle.
Adopt after said structure, the advantage that compared to the prior art the present invention had is: comprise body, on body, lower two ends are equipped with flange, described body is connected with flange split, between body and flange, be provided with support ring, on support ring, lower two ends are provided with the card rail of cross section one-tenth " T " font or " ten " font, flange inner wall and body outer wall all offer and the draw-in groove that blocks rail and be connected, clamping between described support ring and body and flange, the present invention by being provided with the support ring of band card rail between body and flange, can make body and flange removably connect, when flange or body are squeezed while damaging, conveniently replaced, can in ensureing sealing effect, increase the service life like this.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Embodiment
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
As shown in Figure 1: a kind of sealing gasket of plastics air inlet manifold branch of engine, comprise body 1, on body 1, lower two ends are equipped with flange 2, described body 1 is connected with flange 2 splits, between body and flange, be provided with support ring 3, on support ring 3, lower two ends are provided with the card rail 4 of cross section one-tenth " T " font or " ten " font, flange 2 inwalls and body 1 outer wall all offer and the draw-in groove that blocks rail 4 and be connected, clamping between described support ring 3 and body 1 and flange 2, also the both sides of described body 1 can be provided with to flange 2, described body 1 inwall offers the chute that can make support ring slide, the cross section of described flange 2 is triangle or originally semicircle, invention by being provided with the support ring 3 of band card rail 4 between body 1 and flange 2, the card rail 4 of support ring 3 coordinates with the draw-in groove clamping of flange 2 and body 1, can make body 1 and the detachable clamping of flange 2, when flange 1 or body 2 are squeezed while damaging, conveniently replaced, can in ensureing sealing effect, increase the service life like this.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
