Specific embodiment
The concrete structure in this utility model is done with explanation with reference to Figure of description：
Embodiment 1
A kind of automobile-used air inlet pipe can be the air inlet in air inlet pipe, or air-conditioning assembly on engine charge assembly
Pipe, as depicted in figs. 1 and 2, the air inlet pipe 1 in the present embodiment is the rank that the not all equal some pipeline sections of caliber are connected and composed
Ladder-shaper structure, is coated with rubber sheath 2, the inner wall shape of the rubber sheath 2 and 1 outer wall of the air inlet pipe outside air inlet pipe 1
Mating shapes.In this utility model, rubber sheath 2 is coated with outside air inlet pipe 1, the presence of rubber sheath 2 can be played
The effect of sound insulation, and then inflow noise can be reduced to a certain extent, in addition, outside the pipeline near air inlet pipe and air inlet pipe
When rubber sheath collides, the abnormal sound very little (negligible) for sending so as to play a part of to reduce abnormal sound, and can also be played
The effect of protection air inlet pipe.The thickness at 2 each position of the rubber sheath is advisable for 3-4mm.
As further improving：The air inlet pipe 1 includes the first pipeline section 11, the second pipeline section 12 and the 3rd pipe being sequentially connected
Section 13, the external diameter of second pipeline section 12 are more than the external diameter of first pipeline section 11, also greater than the external diameter of the 3rd pipeline section 13,
The rubber sheath 2 is coated on the outside of first pipeline section 11, second pipeline section 12 and the 3rd pipeline section 13.
The tube wall of the air inlet pipe 1 is provided with the interface of evagination, corresponding with the interface on 2 side wall of the rubber sheath
Position forms perforation 3, reserves perforation for connecting pipeline.
Rubber sheath can directly be formed by sulfuration process when the material of air inlet pipe is metal, and work as the material of air inlet pipe
Matter directly can not vulcanize outside air inlet pipe when being plastics and form the rubber sheath, because high temperature during sulfuration can cause air inlet
Pipe deforms, and in turn results in product rejection, therefore can only be by being connected rubber sheath with air inlet pipe using assembling mode, for normal
For the grade external diameter pipeline of rule, it is possible to use strongly rubber sheath is enclosed within outside air inlet pipe, packaging technology is relatively easy, and easily
In realization, and if air inlet pipe is the step structure that the not all equal some pipeline sections of caliber are constituted, assembling difficulty is then increased, this
Art personnel can not use conventional methods installation rubber sheath, arrange the rubber sheath using having in the present embodiment
The high-temperature resistant rubber of elasticity is made, and is installed by the mode that axially (i.e. air inlet pipe axial direction, namely intake manifold length direction) is set with
Outside the air inlet pipe, specifically so can operate in practical operation：When the rubber sheath 2 is installed, will using instrument
Whole rubber sheath 2 is outwards strutted, and is internally formed cavity of the bore more than the air inlet pipe external diameter in rubber sheath, then will be entered
Trachea is inserted into rubber sheath internal cavities, when air inlet pipe is inserted in place, rubber sheath is tensed and is extracted instrument, rubber
Sheath loses support after-contraction and is tightly fitted in air inlet pipe, and this way is applied to conventional equal diameter pipe and stairstepping pipeline,
So as to the fastness that the convenience, aesthetic property and the laminating that improve rubber sheath installation are installed, effect is installed to further enhance laminating
Really, gluing is carried out at 2 each edge of rubber sheath after rubber sheath laminating is installed.
Further, the quantity at least two of the rubber sheath 2, adjacent two rubber sheath 2 one end close to each other
Between form girth joint 21, the structure installed using this stagewise can improve rubber sheath 2 and install in practice operation
Convenience.
In the present embodiment, the girth joint 21 is that adjacent two rubber sheath 2 one end close to each other socket-connects and formed,
As shown in Figure 3 and Figure 4；As another kind of structure：The girth joint 21 is adjacent two rubber sheath 2 one end pair close to each other
Connecing and being formed, the outside of the girth joint 21 is arranged with rubber adapter sleeve 4, annular is formed on the inside of the rubber adapter sleeve 4
Raised 5 or/and annular groove 6, the corresponding site of the adjacent rubber sheath 2 form be suitable to the annular protrusion 5 or/and
Annular groove 6 coordinate annular groove 6 or/and annular protrusion 5, as shown in Figure 5 and Figure 6, using said structure can avoid into
On trachea, position corresponding with girth joint is exposed, and is avoided that 2 edge of each rubber sheath shrinks sliding, so as to improve rubber shield
The using effect of set, and improve aesthetic property.
Further, have on second pipeline section 12 and be suitable to which is split into two-part releasable connection structure vertically,
The releasable connection structure is corresponding with girth joint described in one 21, and the releasable connection structure is screw connection structure.Using this
Structure is planted, if will be overhauled or be changed internal part to second inner tube segment, is conducive to the fractionation of the second pipeline section
And connection.
Embodiment 2
The present embodiment difference from Example 1 is：The rubber sheath 2 is radially docked by left and right halved body
And constitute, not shown in figure.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate this utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need to give to all of embodiment
It is exhaustive.And these belong to connotation of the present utility model it is extended obvious change or variation still fall within it is practical
New protection domain.
