Each bar shaped gear piece outer surface is fixed in the rubber tube head vulcanization, and one end of the nearly seat ring of rubber tube head rest infilters each infiltration hole and ring
In groove.
Further, the radial arrangement for penetrating into hole along seat ring is in the outside of reducing supporting part；Correspondingly may be used in each hole of penetrating into
One end of reducing supporting part bearing of trend is equipped with radial direction deep gouge between circumference where reducing supporting part；The rubber tube head
Close to one end of seat ring radially deep gouge infilter it is corresponding penetrate into hole and rubber tube head be located at part in each radial direction deep gouge with
Seat ring corresponding end-faces are equal.
Further, the inner headed face of the seat ring is fixed with radially inwardly projecting annular flange；Set in the annular flange
There are the multiple vias along the circumferential direction arranged；One end of the nearly seat ring of rubber tube head rest is coated on outside annular flange and infiltered
In each via.
Further, the seat ring, annular flange and reducing supporting part are integrally formed and are plastic material.
The beneficial effects of the invention are as follows：The plastic inlet pipe joint of the present invention, its rubber tube head are fixed on air inlet tube bracket
On, the intensity of rubber tube head is improved, beneficial to improving the steady of attachment structure between engine air inlet tube and electronic throttle joint
Qualitative, durability is good, requirement when reducing assembling to control card band tightener power, cost-effective.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
Fig. 1 is the structural representation of the present invention；Fig. 2 is Fig. 1 A-A sectional views, as shown in the figure：The plastics of the present embodiment enter
Gas-tpe fitting, including air inlet tube bracket and the rubber tube head 2 for being fixed on air inlet tube bracket；The air inlet tube bracket includes seat ring 1
With reducing supporting part；The reducing supporting part is fixed on seat ring 1 and extended to the axial side of seat ring 1；The rubber tube
First 2 are fixed on the outer surface of reducing supporting part；I.e. rubber tube head 2 is coated on the outside of reducing supporting part, passes through reducing
The supporting role of supporting part improves the structural strength of rubber tube head 2, therefore engine air inlet tube is connected with electronic throttle joint
When can suitably increase fastening force, improve the stability of attachment structure, durability is good, reduce assembling when to control card band tightener power
It is it is required that cost-effective.
In the present embodiment, the reducing supporting part includes multiple bar shaped gear pieces 3；The bar shaped gear piece 3 is along the circumference of seat ring 1
Direction arranges；Bar shaped gear piece 3 has certain deformation behavior, therefore by that can produce certain bending during radial load, enters
And the reducing performance of reducing supporting part is realized, when multiple bar shaped gear pieces 3 bend, with the gap between each bar shaped gear piece 3
As bit space is allowed, avoid producing and extrude and damage structure.
In the present embodiment, the seat ring 1 is provided with the multiple infiltration holes 4 along the circumferential direction arranged；In the infiltration hole 4
The diameter parallel of heart line and seat ring 1；The part-structure of rubber tube head 2 makes rubber tube head 2 and air inlet tube bracket knot through stretching into hole
Conjunction is more firm, and structure is more stable.
In the present embodiment, the seat ring 1 is provided with what is communicated with each infiltration hole 4 backwards to a side end face of reducing supporting part
