Abstract
The utility model discloses a pipe joint for connecting an air inlet manifold of an engine with a vacuum pipeline. The pipe joint consists of a fixing ring, an internal ring and a sealing ring, wherein the sealing ring and the fixing ring are arranged inside the air inlet manifold; the sealing ring is positioned on the inner side of the fixing ring; the internal ring is inserted into an internal hole in the fixing ring; the vacuum pipeline is inserted into an internal hole in the internal ring; the outer wall of the sealing ring is tightly attached to the air inlet manifold; and the inner wall of the sealing ring is tightly attached to the vacuum pipeline. The pipe joint has a simple structure and low cost, and realizes functions of connecting and dismounting the vacuum pipeline.
Description
Technical field
The utility model relates to a kind of pipe joint, especially a kind of pipe joint that connects engine intake manifold and vacuum line.
Background technique
Usually can leave vacuum tube joint on the engine intake manifold, be used for connecting vacuum line, provide vacuum to the element that needs vacuum on the vehicle.Because the requirement to the close performance of this joint is sealed is high, needs vacuum line to dismantle from joint easily simultaneously.So general vacuum line joint design more complicated, cost is also very high.
Summary of the invention
The utility model purpose is: propose a kind of pipe joint that is used to connect engine intake manifold and vacuum line, this pipe joint structure is simple, with low cost, satisfy that vacuum line connects and the function of dismounting.
The technological scheme of the utility model is: a kind of pipe joint that is used to connect engine intake manifold and vacuum line; It is made up of retaining ring, interior ring and seal ring; Wherein seal ring and retaining ring all are loaded on the inside of intake manifold and the inboard that seal ring is positioned at retaining ring, and interior ring is inserted in the endoporus of retaining ring, in the endoporus that encircles in vacuum line is inserted into; And the outer wall and the intake manifold of seal ring fit tightly, and the inwall and the vacuum line of seal ring fit tightly.
Have on the outer wall of said retaining ring and be embedded in the intake manifold, to fix the tinsel I of this retaining ring.
But thereby said in the ring an end be shaped on the spring section that several gap form a radial dilatation, and should in the ring inwall on have oblique layout, the tinsel II to prevent that vacuum line from coming off.
The utility model has the advantages that: the pipe joint of the utility model only is made up of retaining ring, interior ring and three parts of seal ring, and the structure of these three parts is all fairly simple, and assembly and disassembly are got up very easy, and can satisfy sealing requirements, and cost is lower.
Description of drawings
Combine accompanying drawing and embodiment that the utility model is done further to introduce at present:
Fig. 1 is the utility model embodiment's a explosive view;
Fig. 2 is the utility model embodiment's an installation process schematic representation;
Fig. 3 is model utility embodiment's a longitudinal section;
Fig. 4 is the structural representation of retaining ring;
Fig. 5 is the structural representation of interior ring;
Wherein: 1 intake manifold, 2 seal rings, 3 interior rings, 3-1 gap, 3-2 tinsel II, 4 retaining rings, 4-1 tinsel I, 5 vacuum lines.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the pipe joint of present embodiment is used for intake manifold 1 and vacuum line 5 are coupled together, and it is made up of retaining ring 4, interior ring 3 and seal ring 2.
As shown in Figure 3; After assembling was accomplished, said seal ring 2 and retaining ring 4 all were installed in the inside of intake manifold 1, and seal ring 2 to be positioned at the inboard of retaining ring 4 (as shown in Figure 2; So-called " inboard " is meant that seal ring is arranged in the sidepiece of retaining ring and is not the endoporus of retaining ring).Interior ring 3 is inserted in the endoporus of retaining ring 4, and vacuum line 5 is inserted in the endoporus of interior ring 3.The outer wall of seal ring 2 and intake manifold 1 closely connected closing, the inwall of seal ring 2 and vacuum line 5 fit tightly.
As shown in Figure 4, have on the outer wall of retaining ring 4 be embedded in the intake manifold 1, to fix the tinsel I 4-1 of this retaining ring, this tinsel I 4-1 embeds in the intake manifold 1, makes retaining ring 4 firmly be fixed on the intake manifold 1.
As shown in Figure 5, thus but an end of interior ring 3 is shaped on the enlarged portion that several gap 3-1 forms a radial dilatation.Also have oblique tinsel II 3-2 on the inwall of interior ring 3,, can make vacuum line 5 from interior ring 3, to come off automatically through the effect of this tinsel II.
Refer again to Fig. 2 and shown in Figure 3, the installation process of present embodiment is as follows:
The part of 1) earlier seal ring 2 being packed into and being used to install this pipe joint on the intake manifold 1.
2) adopt pressure unit that retaining ring 4 is pressed in the intake manifold 1 again.Be pressed in the process of intake manifold 1 at retaining ring 4, the tinsel I 4-1 on the retaining ring can embed in the intake manifold, makes retaining ring be fixed on the intake manifold firmly.
3) then interior ring 3 is inserted in the endoporus of retaining ring 4, this moment, this pipe joint possessed the function of use.
4) when needs connect vacuum line 5; The endoporus of ring 3 gets final product in only need firmly inserting vacuum line 5; Because the spring section of interior ring 3 has certain elasticity; When in insert on vacuum tube road 5, encircling 3 endoporus, spring section will radial dilatation become big, and the extruding force that makes vacuum line 5 receive increases.Tinsel II 3-2 simultaneously on the ring 3 makes vacuum line 5 from interior ring 3, to come off automatically.The vacuum line 5 of this moment need pass seal ring 2; Seal ring outer wall and intake manifold 1 fit tightly; Seal ring inwall and vacuum line 5 fit tightly; So just can seal whole vacuum system, simultaneously vacuum line itself also is fixed, thereby has realized the fixedly effect of vacuum line and sealed vacuum system.If desired vacuum line 5 is extracted, need be by external force.
Certainly, the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
