The middle-section pipe body of the connecting pipe for the air conditioner is connected with the pipe heads by adopting the pipe joints, thus the characteristics of flexible operation, reliable connection and good sealing property are achieved; the middle-section pipe body can be conveniently disassembled when needing to be replaced during ageing; and the middle-section pipe body is the metal composite pipe, and the pipe joints are made of copper alloys, thus the copper quantity is greatly reduced and the product cost is lowered.
Description
Technical field
The utility model relates to a kind of connecting tube, especially a kind of connecting tube that is used for indoor apparatus of air conditioner and outdoor unit.
Background technique
Existing split-type air conditioner comprises indoor set and outdoor unit, is connected through connecting tube between indoor set and the outdoor unit, and refrigerant circulates between indoor set and outdoor unit through connecting tube, realizes exchange heat, reaches refrigeration.Present air conditioner connecting pipe mainly adopts red copper to process, and red copper has superior corrosion resistance, but cost is higher; Some manufacturers adopt metal composite pipe to replace the stage casing body of existing air conditioner connecting pipe in order to reduce manufacture cost, effectively reduce the copper consumption; Save cost, be called the patent of " air conditioner connecting pipe " like Patent Office in the disclosed patent No. on May 18 " 201020596760.0 ", name in 2011, the stage casing body adopts aluminum pipe; Tube head adopts copper pipe, adopt welding technique to be connected between aluminum pipe and the copper pipe, but situation such as leakage weldering, rosin joint appears in welding unavoidably; Cause coolant leakage, and also inconvenient when body aging needs in stage casing are changed.
Summary of the invention
The utility model problem to be solved just provides a kind of air conditioner connecting pipe, has simple in structure, reliable performance, characteristics easy to connect.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of air conditioner connecting pipe, comprise stage casing body and the tube head that is located at body two ends, said stage casing, and said stage casing body is a composite pipe, said stage casing body is connected through pipe joint with tube head.
Further, said pipe joint comprises outer cutting ferrule and interior cutting ferrule, said in the cutting ferrule one end said tube head that is tightly connected, the end tube wall of said stage casing body is clamped between said outer cutting ferrule and the said interior cutting ferrule.
Further, said outer cutting ferrule with said in be connected for screw-thread fit between the cutting ferrule.
Further, said pipe joint also comprises the core of the card that is located between said outer cutting ferrule and the said interior cutting ferrule, and the end tube wall of said stage casing body is clamped between said the core of the card and the said interior cutting ferrule.
Further, said the core of the card is provided with inner conical surface, and said interior cutting ferrule is provided with male cone (strobilus masculinus), and the end tube wall of said stage casing body is clamped between said inner conical surface and the said male cone (strobilus masculinus).
Further, be provided with the damping structure that the stage casing body is increased chucking power between said inner conical surface and the said male cone (strobilus masculinus).
Further, said damping structure comprises the latch that is located on said inner conical surface and the said male cone (strobilus masculinus).
Further, said stage casing body is a metal composite pipe.
Further, said pipe joint is processed by Cuprum alloy.
The beneficial effect of the utility model: adopt pipe joint to connect the stage casing body and the tube head of air conditioner connecting pipe, have flexible operation, connect characteristics reliable, good seal performance, and the stage casing body is aging when needing to change, also can very easily it be disassembled; The stage casing body adopts metal composite pipe, pipe joint to adopt Cuprum alloy, reduces copper consumption greatly, reduces product cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
Embodiment
With reference to Fig. 1, a kind of air conditioner connecting pipe comprises stage casing body 1 and the tube head 5 that is located at stage casing body 1 two ends; Stage casing body 1 is a composite pipe, can plate anticorrosive coat by aluminum pipe, perhaps copper aluminum composite pipes; Tube head 5 can still adopt red copper or Cuprum alloy to replace, and stage casing body 1 and tube head 5 are connected through pipe joint.
Embodiment one: pipe joint comprises outer cutting ferrule 2 and interior cutting ferrule 3; The end tube wall of stage casing body 1 is clamped in outer cutting ferrule 2 and interior cutting ferrule 3, and an end of interior cutting ferrule 3 then is tightly connected with tube head 5, can step be set at an end of interior cutting ferrule 3; Tube head 5 inserts this step, fixes through viscose or welding; , for convenience detach between outer cutting ferrule 2 and the interior cutting ferrule 3 for screw-thread fit is connected.
Embodiment two: and embodiment's one difference is: pipe joint also comprises the core of the card 4 that is located between outer cutting ferrule 2 and the interior cutting ferrule 3; The end tube wall of stage casing body 1 is clamped between the core of the card 4 and the interior cutting ferrule 3, increases chucking power through the core of the card 4, more has preferred; The core of the card 4 one ends are provided with inner conical surface 41; Interior cutting ferrule 3 corresponding end are provided with male cone (strobilus masculinus) 31, and the end tube wall of stage casing body 1 is clamped between inner conical surface 41 and the male cone (strobilus masculinus) 31, utilize tapering to change; The chucking power that provides degree of tightness not wait is fit to the clamping of unlike material tubing.In addition, the damping structure that stage casing body 1 is increased chucking power can be set also between inner conical surface 41 and the male cone (strobilus masculinus) 31, damping structure is the latch that is located on inner conical surface 41 and the male cone (strobilus masculinus) 31, utilizes latch to increase chucking power, perhaps adopts brake pad will possess same effect.
During use, earlier the end tube wall of stage casing body 1 is put between the core of the card 4 and the cutting ferrule 3, put outer cutting ferrule 2 again, simultaneously outer cutting ferrule 2 is spun with interior cutting ferrule 3, in the process that spins, the core of the card 4 promotion of cutting ferrule 2 outside constantly tightens stage casing body 1 down.
