Description
Technical field
The utility model belongs to automobile air conditioner accessories technical field, is related to a kind of wear-resisting type pipelines of automobile air conditioner.
Background technology
Air-conditioning system connecting line is in the layout of vehicle, in the status of a comparative disadvantage, i.e. air-conditioner pipe
The arrangement on road needs to avoid other parts on vehicle, is inevitably close to other parts of surrounding sometimes either from it
It is passed through between its parts.Because connecting line is all disposed near engine mostly, it will usually bear to work from engine
When vibration, cause the abrasion of pipeline and other parts, now at present mostly using outside pipeline sebific duct increase a PP material
Manufactured corrugate sheath, since PP materials do not have good wearability, sebific duct part is ground in long-time, pipeline
Damage is destroyed, secondary refrigerant leakage, and air-conditioning whole system is caused to fail under serious conditions.
Utility model content
The purpose of this utility model is to provide a kind of wear-resisting type pipelines of automobile air conditioner, solves sky in the prior art
The sebific duct of connecting line is adjusted easily to be worn destruction problem.
The technical solution of the utility model is a kind of wear-resisting type pipelines of automobile air conditioner, including air conditioner connecting pipe, air-conditioning connection
The outer surface of pipe is socketed with sebific duct, and the outer surface of sebific duct is socketed with nylon shield spring.
The utility model is also characterized by
The side of nylon shield spring is provided with multiple radiating grooves being mutually parallel, and nylon protects side opposite with radiating groove on spring
It is provided with symmetrical card teeth.
Nylon shield spring is buckled in by the clearance fit between a pair of of card teeth on sebific duct.
Radiating groove is strip structure, and card teeth is arc dentalation.
Sebific duct is adhered to the outer surface of air conditioner connecting pipe.
The beneficial effects of the utility model are a kind of wear-resisting type pipelines of automobile air conditioner of the utility model, simple in structure, performance
Well, facilitate installation, protect sebific duct part in air conditioning for automobiles connecting line, so as to make air conditioning for automobiles normal operation.

In figure, 1. air conditioner connecting pipes, 2. sebific ducts, 3. nylon shield spring, 4. radiating grooves, 5. card teeths.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of wear-resisting type pipelines of automobile air conditioner of the utility model, structure as depicted in figs. 1 and 2, including air conditioner connecting pipe 1,
The outer surface of air conditioner connecting pipe 1 is socketed with sebific duct 2, and the outer surface of sebific duct 2 is socketed with nylon shield spring 3.
As shown in figure 3, the side of nylon shield spring 3 is provided with multiple radiating grooves 4 being mutually parallel, nylon is protected on spring 3 with dissipating
The opposite side of heat channel 4 is provided with symmetrical card teeth 5.
Nylon shield spring 3 is buckled in by the clearance fit between a pair of of card teeth 5 on sebific duct 2.
Radiating groove 4 is stated as strip structure, card teeth 5 is arc dentalation.
Sebific duct 2 is adhered to the outer surface of air conditioner connecting pipe 1.
As shown in figure 4, nylon shield spring 3 it is axially expanded after structure in the form of sheets, the appearance of sebific duct 2 can be directly wrapped in
Then face is fastened by card teeth 5, both ends are tied up securely again with band, manufacturing process very simple, the radiating groove of strip
4 can help sebific duct 2 to radiate in time, prevent the temperature of the sebific duct 2 during use is excessively high to be damaged.
A kind of wear-resisting type pipelines of automobile air conditioner of the utility model uses nylon in the external socket one of air-conditioning duct sebific duct 2
Nylon made of PA66 protects spring 3, because nylon has good mechanical strength, rigidity, toughness, there is very strong mechanical shock absorption and resistance to
Mill property, one side nylon PA66 can keep stronger strength and stiffness at a higher temperature；On the other hand have good wear-resisting
Property nylon shield spring 3 can protect sebific duct 2, be in direct contact the not direct sheet metal component with vehicle body of sebific duct 2, so as to protect sebific duct
2 are not worn destruction, increase the service life on air conditioner connecting pipe road, improve the stability of entire air-conditioning system.
