Abstract
The utility model relates to a hose assembly for automobile air conditioners, which is formed by that on the basis of an existing hose assembly composed of a hose and hose connecting heads installed at both ends of the hose assembly, O-shaped sealing rings are additionally installed between the hose and core pipes in the hose connecting heads. The utility model can effectively improves the sealing performance and can overcome the problem that an original hose assembly is easy to generate the leakage of refrigeration agents to influence the refrigerating effect of an air conditioner. The utility model has the advantages of reasonable design, firm structure, high productive efficiency, favorable sealing performance, long service life, etc. and is suitable for being used as a connecting hose for conveying and circulating refrigeration agents in automobile air conditioners.
Description
The utility model relates to a kind of flexible pipe of delivery cycle refrigeration agent, particularly a kind of rubber hose assembly of automotive air-conditioning system delivery cycle refrigeration agent.
Be used for automotive air-conditioning system and be connected vaporizer, condenser, rubber hose assembly between the parts such as compressor, mainly form by the hose coupling at flexible pipe and flexible pipe two ends, hose coupling wherein comprises the core pipe, overcoat and attaching nut, core pipe top has a boss to be contained among the attaching nut, core pipe bottom has annular groove and is inserted in the flexible pipe port, overcoat is fitted on the flexible pipe port wall, during assembling, need flexible pipe is being withheld between core pipe and overcoat with the machine of withholding again after the coated with adhesive inside and outside the flexible pipe port, because band glue assembling, be not easy to operation, simultaneously, because the thermoplastic soft tube that flexible pipe has selected for use the good C type fabric of anti-seepage property to strengthen, make the hardness of flexible pipe bigger, between core pipe and flexible pipe, produce easily and leak, particularly be used on the car air conditioner, owing to be given a shock for a long time and under the condition of High Temperature High Pressure, move, cause the refrigeration agent seepage easily and influence the refrigeration of air-conditioning.
The purpose of this utility model is design a kind of good seal performance, long service life and the high automotive air conditioning hose assembly parts of manufacturing efficiency.
Automotive air conditioning hose assembly parts of the present utility model comprises flexible pipe and is installed in the hose coupling at flexible pipe two ends, described hose coupling comprises core pipe, overcoat and attaching nut, core pipe top has a boss to be contained among the attaching nut, core pipe bottom has annular groove and is inserted in the flexible pipe port, overcoat is fitted on the flexible pipe port wall, wherein, on the annular groove of tube core bottom the O RunddichtringO is housed.
Accompanying drawing is the structural representation of hose coupling of the present utility model.
Referring to accompanying drawing, the top of core pipe 3 has a boss 2 to be contained among the attaching nut 1, and the bottom of core pipe 3 has annular groove 5 and is inserted in the port of flexible pipe 7, and overcoat 4 is fitted on the port wall of flexible pipe 7, on the annular groove 5 of tube core 3 bottoms wherein O RunddichtringO 6 is housed.During assembling, after packing into O RunddichtringO 6 in the annular groove 5 of core pipe bottom, after attaching nut 1 and overcoat 4 are inserted in from the lower end of core pipe 3, port with flexible pipe 7 is inserted between core pipe 3 and the overcoat 4 again, adopt that segmentation is withheld, one-time formed technology is withheld overcoat on the flexible pipe port withholding on the machine at last, the flexible pipe port is pressed between tube core and the overcoat.Owing between core pipe and flexible pipe, installed the O RunddichtringO additional, can improve the sealability of joint effectively, do not need coating adhesive again, also be convenient to assembly operation, the manufacturing efficiency height.
The utlity model has reasonable in design, sound construction, production efficiency height, good seal performance and service life The advantages such as length are adapted at doing in the air conditioner for automobile connecting hose use of delivery cycle cold-producing medium.
