Embodiment
Fig. 1 and Fig. 2 illustrates the link 1 as target of the present utility model.
Described link is preferably annular, has tubular outer part 11; Especially, two elastic tongue pieces 15 are incorporated on exterior section, and each described tongue piece has the tooth 14 on the outer surface that is positioned at for the axis X of link; Each described tongue piece 15 axially extends the end away from link 1 to be provided with assurance device 155 on free terminal, namely, and this assurance device preferably has corrugated surface; Alternatively, equal assurance device can be adopted to replace the mentioned above and device shown in figure, such as co-molded rubber terminal, groove of special shape etc.
Preferably, at each described tongue piece 15 from the region that described link 1 is incorporated to, be provided with two slots 156,156 ' at each tongue piece towards the length that described link extends, therefore make the whole side 153,154 of described tongue piece be separated with described link 1.
Because such structure, after applying active force towards the axis X of described link 1 to the assurance device 155 be arranged on described link 1, described tooth 14 also can move to link axis.
According to the utility model, even if pipeline 2 is assembled on described link, described tooth 14 also can move.As depicted in figs. 1 and 2, described link 1 inside is provided with through hole 12, and bore 13; The size of described bore is greater than the diameter of described through hole; Therefore, the diameter of described seat is configured such that this pipeline 2 can insert, until the axial end 22 of pipeline 2 abuts against shoulder in axle, in this axle, shoulder is limited by the diameter difference between hole seat 13 and through hole 12.
Preferably, as Fig. 4 and Fig. 6 is visible, when having an augular offset for tongue piece 15, be provided with chute 131, for receiving the radial protuberance 21 be arranged on pipeline; Especially, the preferable shape of radial protuberance is made up of middle wheel shaft 211, and pipeline 2 and the enlarged portion 212 be arranged on the outer radial free end of described protuberance couple together by this middle wheel shaft 211; Therefore, the Thickness Ratio chute 131 of described enlarged portion 212 is larger in the radial height of its closed end 132; In other words, the tolerance limit of described chute 131 and described radial protuberance 21 makes on assembling position, and this pipeline 2 is locked on link pipeline seat 13; Interchangeable embodiment also may be used for described locking, such as simple protuberance on the one element, and the respective recess on other elements, and/or welding two parts, and/or is threaded, etc.
As mentioned above, even if when described link 1 and described pipeline 2 fit together, described briar tooth 14 also can move towards described link axis X; In the preferred embodiment shown, by means of the active force be applied on the free terminal 144 of tongue piece 15, by means of the interior shape 157 of described tongue piece, and rely on their elasticity, this movement is possible.
According to a preferred embodiment of the present utility model, the elasticity of described tongue piece comes from the elasticity of link, and the material coming from link is elastic type, and this of such as plastics or rubber is true; Other the alternative mode realizing tongue piece movement can by pivot/spring (in this case, described tongue piece is not forming of showing in the embodiment as described above) composition between described tongue piece and described link.
With regard to the interior shape of the internal surface 157 of each tongue piece 15, the inner radial of each tongue piece must be made to move not by the interference of pipeline external surface; Such as, described interior shape 157 can be circular, and ideally, the line limited with the axial obstacle of pipeline is tangent.
The assembly obtained by described link 1 and described pipeline 2 removably can be connected with the link seat 31 be arranged on function element 3; For function element, it is defined as any device of removably demand conduit assembly, preferably guarantees those devices of the sealing between described pipeline and described device; The example of function element can be air filtering chamber, resonator, flowermeter etc.
As shown in the figure, particularly Fig. 3 to Fig. 8, on described function element, namely on the filter housings being suitable for combustion air suction loop, be provided with link seat 31, this link seat 31 is made up of cylindrical casing group, and the inside diameter of this cylindrical casing is suitable for the tubular cylinder shape part 11 inserting described link 1; On described link seat 31, be provided with two recesses 312, described recess 312 has such size: once described link is positioned at it on the mounting point of function element 3, then the size of this recess makes briar tooth 14 insert.Due to the elasticity of described link, its outer surface and internal surface can have such size: guarantee described link seat and the corresponding interference of described pipeline, guarantee the sealing between the inner space that pipeline 2 limits and external environment condition.
According to alternative embodiment, one or more pad can be provided with on link, on function element, on pipeline, to guarantee the sealing of described parts.
During work, by the end of described pipeline 2 is pushed to be arranged on the pipeline seat 13 on described link 1, pipeline 2 can be assembled on described link 1; More particularly, described pipeline 2 is aimed at angularly with described link seat, radial protuberance 21 is aimed at described chute 131, thus when described pipeline axial pushes described link to, each protuberance 21 slides along described chute 131 respectively, until due to its tolerance limit, and the interference between described two parts, described protuberance is engaged on described chute.
Then, the described pipeline 2 fitted together with described link 1 can with function element 3, that is, be applicable to the filtering chamber of vehicle, fit together; By being inserted in by the tubular cylinder shape exterior section 11 of described link on the link seat 31 that is arranged on described filtering chamber, until the tooth 14 be arranged on described link is engaged with the recess be arranged on link seat 31 respectively, complete this assembling.As mentioned above, the sealing between described link 1 and described link seat 31 is guaranteed by the elasticity/elasticity of described link and about the relevant tolerance limit of the mechanical interface of pipeline 2 and function element 3, and the sealing between described pipeline 2 and described link.
If pipeline 2 must be separated from function element 3 for some reason, so just enough towards the axis X direction applying active force of described link 1/ pipeline 2 to the assurance device 155 be arranged on each tongue piece 15 of described link 1, described tooth is moved towards the axis X of these parts, until it unclamps from respective recess 312, thus described link 1 and pipeline 2 axially can be extracted from described link seat 311; As mentioned above, described tooth 14 is configured to: even if described link 1 and described pipeline 2 fit together, due to interior shape 157 and the elasticity due to described tongue piece, described tooth also can move towards the axis X of described link.
The utility model can have various modifications and variations, and all modifications and modification all belong to category of the present invention.In addition, all details can by other technically equivalence element substitute.
In practice, the material of all uses, and shape and possible size, can change according to demand, not depart from the protection domain of claim.
