Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a high temperature resistant air intake hose for automobiles. Background Art

[0002] The internal threaded molded intake neoprene hose is a rubber hose with specific specifications and characteristics. It is mainly used in automobile intake manifolds, embedded nuts, and computer display screen frames. The material of this hose is usually chloroprene rubber. This material has a wide range of uses in various industrial applications due to its good oil resistance, heat resistance, acid and alkali resistance, and wear resistance.

[0003] The air intake hose of a car is usually connected to the engine's supercharger or directly to the engine. The vibration generated by the engine when it is working will also affect the hose. Although the hose has good toughness, after the vehicle has been used for too long, the engine components and the shock-absorbing structure under the engine will age, causing the engine vibration to intensify. Over time, the hose will be frequently subjected to the pulling force exerted by the engine's directional vibration, which will cause the hose to be easily affected by the pulling force and fatigue, resulting in local fractures, so that external dust can enter the engine without passing through the air filter and participate in combustion, aggravating engine wear and affecting the engine's service life.

[0032] Embodiment 1:

[0033] A high temperature resistant air intake hose for automobiles, such as Figure 1-Figure 4As shown, it includes an inner hose 1, the outer surface of the inner hose 1 is connected with a mesh cloth 6, the mesh cloth 6 is made of steel wire weaving and then spot welding, and has good tensile resistance; the outer surface of the mesh cloth 6 is connected with an outer hose 2, the inner hose 1 and the outer hose 2 are both made of chloroprene rubber, and the mesh cloth 6 is clamped by the inner and outer hoses 2, so as to extend the service life of the hose, and effectively avoid the phenomenon of fatigue fracture caused by frequent pulling of the hose; tightening openings 4 are provided at both ends of the inner hose 1 and the outer hose 2, and the outer surface of the tightening opening 4 is connected with a clamping ring 5, the clamping ring 5 is plum blossom-shaped, and two groups of clamping rings 5 ​​and tightening openings 4 are provided, and two clamping rings 5 ​​are placed on the tightening openings 4 at both ends of the hose. At this time, the staff uses pliers or stamping equipment to press the clamping ring 5 into a plum blossom shape, so that the inner hose 1, the outer hose 2 and the mesh cloth 6 are firmly fixed, and the loosening and falling off of the structure are effectively avoided.

[0034] See also Figure 1-Figure 4 In the above embodiment, a thread 3 is provided on one side of the inner rubber hose 1 to facilitate the connection of the air intake hose with the accessories on the car.

[0035] Embodiment 2:

[0036] On the basis of the above-mentioned embodiment 1, although the service life of the hose can be effectively extended by providing an outer hose 2, a tightening mouth 4, a clamping ring 5 and a mesh cloth 6; however, the temperature inside the engine compartment is relatively high, which has a certain impact on the service life of the hose; now, by providing a heat insulating jacket 7, a heat insulating hoop sleeve 8, a clamp 9 and a bolt 10, the heat resistance and service life of the hose can be improved.

[0037] See also Figure 1 , Figure 2 and Figure 4 In the above embodiment, the outer surface of the outer hose 2 is connected with a heat insulating jacket 7, and the outer side of the heat insulating jacket 7 is sleeved with a heat insulating hoop 8. Two heat insulating hoop 8 are provided, and the two heat insulating hoop 8 are vertically distributed. The hose is wrapped by the heat insulating jacket 7 and the heat insulating hoop 8, and the influence of the heat in the engine room on the hose is reduced, thereby improving the heat resistance and service life of the hose; the outer surface of the heat insulating jacket 7 is connected with a clamp 9, and the outer surface of the clamp 9 is penetrated by bolts 10. Two groups of clamps 9 and bolts 10 are provided. The heat insulating jacket 7 is detachably connected to the outer hose 2 through the clamp 9 and the bolts 10.

[0038] The implementation principle of the utility model is as follows: first, an inner hose 1 is made by using a mold. After demoulding, the staff wraps the mesh cloth 6 around the outer ring of the inner hose 1 and puts it into another mold for injection molding, thereby forming a sandwich structure of the inner hose 1 and the outer hose 2 sandwiching the mesh cloth 6, reducing the phenomenon of the mesh cloth 6 falling off. After the inner hose 1 and the outer hose 2 are made, the staff can directly take out the mold core at the top of the inner hose 1, and since there is a thread 3 at the right end of the inner hose 1, the mold core at the right end is taken out by rotation, and then the staff places two clamping rings 5 ​​on the tightening openings 4 at both ends of the hose. At this time, the staff uses pliers or stamping equipment to press the clamping ring 5 into a plum blossom shape, thereby firmly fixing the inner hose 1, the outer hose 2 and the mesh cloth 6, effectively preventing the structure from loosening and falling off, and then the staff directly covers the heat insulation jacket 7 on the outside of the outer hose 2, and then the staff pulls open the heat insulation hoop sleeve 8 and uses the clamp 9 and bolts 10 to fix the heat insulation jacket 7 to the outer hose 2;

[0039] When the hose is in use, the inner and outer hoses 2 are clamped with a mesh cloth 6, which is made of spot-welded steel wire and has good tensile resistance. The mesh cloth 6 withstands the tensile force applied to the hose during engine vibration, thereby extending the service life of the hose and effectively avoiding fatigue fracture caused by frequent pulling of the hose. At the same time, the hose is wrapped by the provision of a heat-insulating jacket 7 and a heat-insulating hoop 8 to reduce the impact of heat in the engine compartment on the hose, thereby improving the heat resistance and service life of the hose. At the same time, the two heat-insulating hoop sleeves 8 are provided to shield the interface position of the intake hose and the clamp 9 to reduce the impact of high temperature in the engine compartment on it.
