Abstract
The utility model relates to a pipeline connector of an automobile air-conditioner system. The pipeline connector of the automobile air-conditioner system is particularly used in connection of pipelines in the automobile air-conditioner system and comprises an aluminum pipe fitting, an iron inner tooth nut used for connecting outer tooth connectors on the pipelines in the automatic air-conditioner system are embedded at one end of the aluminum pipe fitting in a sleeved mode, and the other end of the aluminum pipe fitting is provided with a reverse three-hook. A knurl threaded lining is etched at the tail portion of the reverse three-hook, and an aluminum sleeve is sleeved on the aluminum pipe fitting, pressed in a punching mode and covers an aluminum pipe connector. A rubber pipe is inserted into the reverse three-hook of the aluminum pipe fitting and clamped through a mold so that the knurl threaded lining can be embedded into the inner wall of the rubber pipe, and the main part aluminum sleeve of the pipe connector can be fully clamped. The pipeline connector of the automobile air-conditioner system has the advantages that the rubber pipe and the aluminum pipe fitting can be fully matched so as to enhance intensity and seal, leakage possibility is reduced, reworking is reduced and economical cost is saved.
Description
Technical field
The utility model relates to a kind of automotive air conditioning system pipeline joint.
Background technique
Car air conditioner has become the important component part of automobile, and the Placement of existing automotive air conditioning system pipeline is that aluminium matter pipe fitting connection rubber tube place directly adopts three hook techniques to add the form of aluminium cover.Such Placement can only reach cooperation by simple compression mode, can not guarantee to reach intensity and the sealing of appointment fully, and the pipe leakage rate is large thus, needs to increase to do over again the waste financial cost.
The model utility content
The purpose of this utility model provides a kind of automotive air conditioning system pipeline joint, connection especially for pipeline in the automotive air-conditioning system, can not guarantee to reach intensity and the sealing of appointment fully with the Placement that overcomes traditional pipeline, and cause the pipe leakage rate large, need to increase and do over again, the deficiency of waste financial cost.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of automotive air conditioning system pipeline joint comprises aluminium matter pipe fitting, one end of aluminium matter pipe fitting is nested with tooth nut in the irony, the afterbody of three hooks of the other end is carved with annular knurl screw thread liner, three hooks and annular knurl screw thread liner overcoat have sebific duct, and overlapping again on the sebific duct has the aluminium cover.
The beneficial effects of the utility model are: can clamp in the sebific duct leather sheath falling the annular knurl screw thread liner that the afterbody of three hooks engraves, sebific duct and aluminium matter pipe fitting are more fully cooperated strengthened intensity and the sealing that is connected, reduced leakage probability, reduced and done over again and then saved financial cost.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the described a kind of new tube joint of the utility model embodiment.
Among the figure: 1, tooth nut in the irony; 2, aluminium matter pipe fitting; 3, aluminium cover; 4, sebific duct; 5, annular knurl screw thread liner; 6, fall three hooks.
Embodiment
As shown in Figure 1, the described a kind of automotive air conditioning system pipeline joint of the utility model embodiment, comprise aluminium matter pipe fitting 2, one end of aluminium matter pipe fitting 2 is nested with tooth nut 1 in the irony, the other end is provided with down three hooks 6, the afterbody of three hooks 6 is carved with annular knurl screw thread liner 5, and three hooks 6 that fall have sebific duct 4 with annular knurl screw thread liner 5 overcoats, and sebific duct 4 outer again covers have aluminium to overlap 3.During concrete the use, tooth nut 1 in the irony on the aluminium matter pipe fitting 2 is used for connecting the upper outside tooth joint of automotive air-conditioning system pipeline.Aluminium cover 3 adopts impact style, is pressed into the specified position of aluminium matter pipe, sebific duct 4 is inserted three hooks, 6 places of aluminium matter pipe fitting 2, makes annular knurl screw thread liner 5 be inserted into sebific duct 4 inwalls, has reinforced sealability on original basis.Aluminium matter pipe joint is pressed into first aluminium cover 3 parcels, then compresses with specialized mould, is installed in the automotive air-conditioning system after after tested again, is used for the connection of system pipeline.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, all drops within the protection domain of the present utility model.
