Abstract
The utility model relates to an automotive air-conditioner refrigerating pipeline structure, which comprises an integrated pressure plate. A high-pressure connector and a low-pressure connector are respectively arranged on one lateral surface of the integrated pressure plate, and a high-pressure pipeline and a low-pressure pipeline are respectively welded on the other lateral surface of the integrated pressure plate to form an integrated structure; an integrated block is welded on the middle part of the high-pressure pipeline; a nut is arranged at the tail end of the high-pressure pipeline; a profile is arranged between the nut and the integrated block; a hard pipe is arranged on the profile; a high-pressure injection valve is arranged at one end of the hard pipe; and a low-pressure pressure plate is arranged at the tail end of the low-pressure pipeline. Compared with the conventional structure, the integrated structure formed by the high-pressure pipeline, the low-pressure pipeline and parts through the integrated pressure plate has the advantages of reducing two connecting points and eliminating the hidden trouble of refrigerant leakage produced at the two connecting points; and the work efficiency during production and assembly is improved by integrated design.
Description
Technical field
The utility model relates to the air conditioning for automobiles field, relates in particular to a kind of automobile air conditioner refrigerating pipe line structure.
Background technology
The effect of air conditioning for automobiles is that realization is to air in a car compartment refrigeration, heating, ventilation and purification, for the personnel that ride provide comfortable environment by bus.Traditional air conditioning for automobiles pipeline structure is respectively parts such as high pressure hard tube and low pressure hard tube, lean on two independent pipeline pressing plates to be threaded, but there is following shortcoming in this structure:
(1) high pressure hard tube and low pressure hard tube respectively with the pipeline pressing plate on connector be tightly connected, during installation, need binding thread, pipeline is reversed, and receives the pipeline of torsional shear stress to be prone to premature fatigue and damages, and causes that cold-producing medium leaks.
(2) independent pipeline pressing plate increases operation with the connected mode of pressure duct, low pressure line when the assembling respectively, influences manufacturing schedule.
The utility model content
The applicant provides a kind of simple in structure, easy-to-install automobile air conditioner refrigerating pipe line structure to these shortcomings in the above-mentioned existing production.
The technical scheme that the utility model adopted is following:
A kind of automobile air conditioner refrigerating pipe line structure comprises an integrated pressing plate, and a side of said integrated pressing plate is respectively equipped with high pressure connector and low pressure connector; The another side of integrated pressing plate welds pressure duct respectively and low pressure line constitutes integral structure; At the middle part of pressure duct welding integrated package, at the end of pressure duct nut is installed, between nut and the integrated package section bar is installed; Hard tube is installed on the section bar, and an end of hard tube is installed high pressure and is filled valve; End at low pressure line is installed the low pressure pressing plate.
It is further characterized in that:
The caliber of said low pressure line is greater than the caliber of pressure duct.
The beneficial effect of the utility model is following:
Through the structure of integrated pressing plate with pressure duct and low pressure line and parts formation integral type, compare with existing structure, reduce by two tie points, eliminate this two places tie point and produced the hidden danger that cold-producing medium leaks; And the design of integral type has improved the operating efficiency when producing assembling, has saved after-sales service man-hour, has reduced cost of transportation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 1; A kind of automobile air conditioner refrigerating pipe line structure; Comprise an integrated pressing plate 1; One side of integrated pressing plate 1 is respectively equipped with high pressure connector 1-2 and low pressure connector 1-1, welds pressure duct 2 and low pressure line 3 formation integral structures respectively with integrated pressing plate 1 adjacent another side, and the caliber of low pressure line 3 is greater than the caliber of pressure duct 2.At the middle part of pressure duct 2 welding integrated package 4, these integrated package 4 integrated ternary pressure switch and liquid-sighting glass.At the end equipment nut 9 of pressure duct 2, fabricated structural shape 5 between nut 9 and the integrated package 4 is installed hard tube 6 on the section bar 5, and an end of hard tube 6 is installed high pressure and dashed notes valve 7.End at low pressure line is installed low pressure pressing plate 8.Arrow is represented the flow direction of high pressure draught and low-pressure air current among the figure., compare the structure of pressure duct 2 through integrated pressing plate 1, reduce by two tie points, eliminated this two places tie point and produced the hidden danger that cold-producing medium leaks with existing structure with low pressure line 3 and other parts formation integral type; And the design of integral type has improved the operating efficiency when producing assembling.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the basic structure of the utility model, the utility model can be done any type of modification.
