Abstract
The utility model belongs to the field of automotive spare parts and particularly provides a heat-shrinkable tubing for an automotive oil pipe, which is used for communicating an oil way for an automobile. The heat-shrinkable tubing comprises a tubular reducer pipe and a socketed pipe, wherein the reducer pipe is used for shrinking; the socketed pipe extends out from two ends of the reducer pipe and is integrated with the reducer pipe; the diameter of the reducer pipe is greater than that of the socketed pipe; the reducer pipe and the socketed pipe are integrated through conical transition pipes; a plurality of shrinkable reinforcing components are axially arranged in the reducer pipe. The heat-shrinkable tubing has the advantages that the reducer pipe is tightened on a copper pipe through heating, the socketed pipe can be fixed on the copper pipe through the reinforcing ribs arranged inside the reducer pipe, and meanwhile, the tenacity and strength of the socketed pipe are improved.
Description
Technical field
The utility model belongs to auto parts machinery field, specifically a kind of for giving the heat-shrinkable T bush for automobile oil pipe of automobile conducting oil circuit.
Background technique
Automobile oil pipe has three kinds substantially, and gasoline pipe is to connect petrol pump and engine nozzle, is used to provide fuel oil.Also have power-assisted oil pipe, for steering box provides power-assisted oil, thereby reach the object that alleviates steering drag.Brake oil pipe is to connect brake pump and brake block fore-set, and when we step on brake, brake pump can be by brake oil to brake block pressure, two brake block extruding brake discs, thus reach the object that car deceleration stops.
At present, environment protection thermal Heat-Shrinkable Tubings is widely used in automobile pipeline aspect, especially as the oil pipe of oil circuit.The material contracting with heat of heat-shrinkable T bush has utilized macromolecular material elastic memory function, be that shaped semi-crystalline polymer can be after high-energy ray crosslinking with radiation, more than being heated to fusing point, be deformed under external force the shape needing, cold definite type again, when using, it is heated to fusing point again and reverts to again above the front shape of distortion.Most widely used heat-shrinkable T bush in current heat-shrinkable product; for the protection of refrigeration industry Cu-Al connecting pipe or automobile connecting tube, oil pipe etc.; prevent that surface from occurring closing pool and smooth degree is poor; in high-temperature operation situation, in contraction process, easily bubble, air-prevention oxidation effectiveness is not good, affected sleeve pipe safety and stability in use.
Summary of the invention
The utility model, for the shortcoming existing in above-mentioned technology, proposes a kind of heat-shrinkable T bush for automobile oil pipe of long service life simple in structure.
The utility model provides following technological scheme:
Heat-shrinkable T bush for automobile oil pipe, it comprise tubulose for the reducer pipe that shrinks and be located at the socketed pipe that reducer pipe two ends are made into integration with it, the diameter of described reducer pipe is greater than socketed pipe, transition tube one by taper between reducer pipe and socketed pipe is connected, and is axially arranged with some contraction stiffening elements in reducer pipe.
Described stiffening element is the stiffening rib that is axially disposed within reducer pipe inwall.
The cross section of described stiffening rib is triangle or trapezoidal or circular arc.
The utility model has the advantages that by the heating of reducer pipe is tightened up on copper pipe, inner stiffening rib can be fixed on sleeve pipe on copper pipe well, has improved toughness and the intensity of sleeve pipe simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to schematic diagram.
Embodiment,
As shown in Figure 1 and Figure 2, heat-shrinkable T bush for automobile oil pipe, copper pipe 3 is through this sleeve pipe, it comprise tubulose for the reducer pipe 1 that shrinks and be located at the socketed pipe 2 that reducer pipe 1 two ends are made into integration with it, the diameter of described reducer pipe 1 is greater than socketed pipe 2, transition tube one by taper 4 between reducer pipe 1 and socketed pipe 2 is connected, and is axially arranged with some contraction stiffening elements in reducer pipe.
Wherein, stiffening element is the stiffening rib 5 that is axially disposed within reducer pipe inwall, reducer pipe 1 on copper pipe 3 after heat shrink the existence due to stiffening rib 5 can improve tightness and stability.
Wherein, the cross section of stiffening rib is triangle or trapezoidal or circular arc.
Claims (3)
1. for the heat-shrinkable T bush of automobile oil pipe, it comprise tubulose for the reducer pipe that shrinks and be located at the socketed pipe that reducer pipe two ends are made into integration with it, it is characterized in that: the diameter of described reducer pipe is greater than socketed pipe, transition tube one by taper between reducer pipe and socketed pipe is connected, and is axially arranged with some contraction stiffening elements in reducer pipe.
2. the heat-shrinkable T bush for automobile oil pipe according to claim 1, is characterized in that: described stiffening element is the stiffening rib that is axially disposed within reducer pipe inwall.
3. the heat-shrinkable T bush for automobile oil pipe according to claim 2, is characterized in that: the cross section of described stiffening rib is triangle or trapezoidal or circular arc.
