Abstract
The utility model relates to a metal soft pipe specially used for an automobile air conditioner, belonging to the technical field of connecting soft pipe; the pipe body of the metal soft pipe consists of an internal layer and an external layer; the internal layer is a metal corrugated pipe and the external layer is a metal screen sleeve; the end of the metal corrugated pipe is a straight edge section; the internal end of the connecting pipe is inserted in the straight edge section; the metal screen sleeve is buckled on the external round of the connecting pipe by a pressing ring which is sheathed outside the metal screen sleeve; the straight edge section of the corrugated pipe, the connecting pipe, the steel screen sleeve and the pressing ring are welded together; the structure type of the metal soft pipe is characterized in that: a transition area is arranged between the joint (hard pipe) and the corrugated pipe (soft pipe) and can effectively transmit the vibration to the whole corrugated pipe so as to lead the vibration to be absorbed; the welding part is arranged on the hard pipe and basically bears no vibration, thus greatly prolonging the fatigue life of the product.
Description
Technical field
The utility model relates to a kind of metallic hose, and especially a kind of car air conditioner special-purpose metal flexible pipe belongs to the connection technical field of hoses.
Background technique
The used for automobile air conditioning flexible pipe is mainly used in the car air conditioner pipeline, and an end connects air condition compressor, and an end connects air-conditioning duct, and major function is that displacement etc. is installed in absorbing, compensation.Manyly in the past use rubber hose, because there is non-refractory in rubber hose, and defective such as easily wear out, now substituted by metallic hose gradually.The structure of existing this metal-like hose is that bellows, net and joint directly weld.Since vibration source normally from joint to the bellows transmission, and joint is a rigid pipe, bellows is a flexible member, the shortcoming of therefore existing bellows structure is that joint and bellows joint are that weld seam and welding heat affected zone can bear bigger vibrations, flexible pipe causes flexible pipe lower working life usually at weld seam and welding heat affected zone fatigue cracking.
The model utility content
The purpose of this utility model is: at the shortcoming that above existing used for automobile air conditioning metallic hose exists, proposes a kind of structure that weld seam and welding heat affected zone bear vibrations, raising product car air conditioner special-purpose metal flexible pipe of fatigue life that reduces.
In order to reach above purpose, the body of car air conditioner special-purpose metal flexible pipe of the present utility model is by inside and outside two-layer the composition, and described internal layer is a metal bellows, and described skin is the wire net.The termination of described metal bellows is a straight section, the inner that plug-in mounting is taken in the described straight section, described metal net is withheld on the adapter cylindrical by being enclosed within its outer crimp rings, and described bellows straight section, adapter, wire sets and crimp rings are welded each other and be connected.
The characteristics of this structural type are to form transition zone between joint (hard tube) and bellows (flexible pipe), can effectively shock transfer be absorbed to whole bellows, the weld seam position is on the hard tube, does not bear vibrations substantially, thereby has improved the anti-fatigue life of product greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an embodiment's of the utility model a structural representation.
Embodiment
Embodiment one
The car air conditioner special-purpose metal flexible pipe of present embodiment as shown in Figure 1, body is by inside and outside two-layer the composition, internal layer is a stainless steel metal bellows 1, skin is a stainless steel wire sets 2.What bellows 1 adopted is the helical fissure pipe of termination band straight section, and rigidity is taken in the straight section that the inner of 3 is inserted into the bellows termination and supported the bellows straight flange, and crimp rings 4 is tightly withheld wire sets 2 and bellows straight section and taken on 3.At last, bellows 1 straight section, adapter 3, wire sets 2, crimp rings 4 quaternities are welded to connect, and the weld seam of this welding is on the excircle of rigidity adapter 3, ringwise.
The joint that is connected with air-conditioning duct can directly weld with taking over, also can directly be connected by taking over air-conditioning duct, therefore, being connected to being connected of rigid pipe and rigid pipe herein.
Facts have proved that the car air conditioner special-purpose metal flexible pipe of present embodiment has advantage simple in structure, that damping property good, fatigue life is high, compare to have significant substantive distinguishing features with existing general-utility car idle call metallic hose.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
1. car air conditioner special-purpose metal flexible pipe, body is by inside and outside two-layer the composition, described internal layer is a metal bellows, described skin is the wire net, it is characterized in that: the termination of described metal bellows is a straight section, the inner that plug-in mounting is taken in the described straight section, described metal net is withheld on the adapter cylindrical by being enclosed within its outer crimp rings, and described bellows straight section, adapter, wire sets and crimp rings are welded each other and are connected.
2. according to the described car air conditioner special-purpose metal of claim 1 flexible pipe, it is characterized in that: described bellows is the spirality corrugated stainless steel tubing of band straight section, and described skin is the stainless steel wire sets.
3. according to the described car air conditioner special-purpose metal of claim 1 flexible pipe, it is characterized in that: described adapter is inserted in the bellows straight flange, described wire netting is enclosed within outside the bellows and is pressed in bellows straight flange and the adapter by latch closure, and described bellows straight section, adapter, wire sets and crimp rings quaternity each other are welded to connect.
