Specific embodiment
As shown in Figure 1-3, a kind of automotive air-conditioning system exhaust hose, including sebific duct and connector 3, sebific duct include one synthesis
Sebific duct ontology 1 and connecting tube 2, the both ends of sebific duct ontology 1 be separately connected a connecting tube 2, the outer surface of connecting tube 2 is equipped with outer
Screw thread, connecting tube 2 are connected through a screw thread with connector 3, and connector 3 includes first interface 4 and second interface 5, first interface 4 and second
The inner wall of interface 5 is equipped with internal screw thread, and first interface 4 is connected to second interface 5, and the inner wall of first interface 4 is equipped with rubber layer 6, rubber
There are the gap of annular between glue-line 6 and the inner wall of first interface 4, gap forms jack 7, and when one end of connecting tube 2, insertion is inserted
When in hole 7, rubber layer 6 is filled with the inner wall of connecting tube 2 and is contacted.When the exhaust hose is connect with other pipelines (such as aluminum pipe)
When, it can directly be connect with other pipeline threads by the second interface 5 of connector 3.Rubber layer 6 on first interface 4 with connect
The tube wall of pipe 2 fills contact and is closely affixed, and avoids gas leakage, solves shielded layer poor flexibility in the prior art and will appear gas leakage
The problem of.
Specifically, the internal diameter of connecting tube 2 is greater than the internal diameter of sebific duct ontology 1, the end of rubber layer 6 can be with sebific duct ontology 1
The end of one end be closely affixed.If the internal diameter of connecting tube 2 is identical with the internal diameter of sebific duct ontology 1, rubber layer 6 can protrude sebific duct
The inner wall of ontology 1 makes the inner wall of rubber layer 6 when rubber layer 6 is inserted into sebific duct (specifically in connecting tube 2) as far as possible
It is flushed with the inner wall of sebific duct ontology 1, one comes for gas outlet, 6 end of rubber layer of protrusion is reduced by airflow scouring, and prolong
Long rubber layer 6 uses time, the air pressure change of two air-flows occurred to reduce the variation due to internal diameter.
Specifically, the outer surface of sebific duct ontology 1 is equipped with several retainer plates 8, retainer plate 8 and sebific duct ontology 1 pass through elastomer block 9
Connection, elastomer block 9 is circumferential to be set on sebific duct ontology 1.When sebific duct ontology 1 is fixed onboard, the fixed point meeting of sebific duct ontology 1
It is fixed, and hot gas or cold air can be discharged in air-conditioning exhaust hose in different season uses, and bring exhaust hose
Rising-heat contracting-cold, the mainly rising-heat contracting-cold of sebific duct ontology 1, and for that can be fixed at being fixed of sebific duct ontology 1, it limits
Its rising-heat contracting-cold, to influence its service life, the setting of retainer plate 8 can make retainer plate 8 as fixed point, in this way
Retainer plate 8 is fixed, and is connected between retainer plate 8 and sebific duct ontology 1 by elastomer block 9, and elastomer block 9 guarantees glue to provide space
The normal rising-heat contracting-cold of tube body 1.
Specifically, being coated with epoxy rubber coating in sebific duct ontology 1.It, can be with dirt in air due to air quality difference
Object is contaminated, the setting of epoxy rubber coating increases the antiseptic property of sebific duct ontology 1, improves its service life.
Specifically, being equipped with sound insulation chamber in the tube wall of sebific duct ontology 1, sound insulation is intracavitary to be filled with sound-proof material 10.Air-flow flows over
Cheng Zhonghui hits the inner wall of sebific duct ontology 1, generates noise, and the setting of sound-proof material 10 reduces noise.
It is worth noting that sebific duct one end jointing, the other end is not connect with connector 3 in Fig. 1, skill is understood to facilitate
Art scheme.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, although referring to before
Embodiment is stated the utility model is described in detail, it for those skilled in the art, still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features.It is all this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
