Description
Technical field
The utility model is related to air conditioner connecting pipes, particularly a kind of full corrugated connecting tube.
Background technology
Split-type air conditioner is made of indoor unit and outdoor unit two parts machine, the larger compressor of noise, aerofoil fan etc.
It is placed in outdoor unit, electric control circuit component and indoor heat exchanger etc. is mounted in indoor unit, indoor unit and outdoor unit
Indoor and outdoors are separately mounted to, by refrigerant two unit actings are made to carry out heat exchange, refrigerant is in outdoor unit and interior
It is circulated between machine, it is necessary to which high leakproofness air conditioner connecting pipe is as flow channel, air conditioner connecting pipe is used to connect in air conditioning chamber
Machine and outdoor unit are the unique passages circulated between two units, therefore air conditioner connecting pipe plays an important role.Together
When, have to air conditioner connecting pipe in thermal conductivity, corrosion resistance, the stability of high temperature cryogenic mechanical performance etc. and accordingly
It asks.
, it is necessary to exert a force to air conditioner connecting pipe, especially during connecting tube connection air conditioner indoor unit and outdoor unit is used
It is the end of connecting tube, since the end of air conditioner connecting pipe is installation end, in installation process, easily makes the end of air conditioner connecting pipe
Flat deformation occurs for portion so that latus rectum reduces in the pipe of connecting tube, make a difference bore flow the problem of, on solving
Problem is stated, existing connecting tube uses reducing connecting tube, connecting tube is arranged to the reducing knot that both ends diameter is big, mid diameter is small
Structure, meanwhile, in order to which connecting tube is made to adapt to different installation sites and building structure, connecting tube is designed with to the knot of bellows segment
Structure, because when carrying out air-conditioning installation at the scene, since installation site is different with the position of room air conditioner preset hole, connecting tube needs
Different degrees of bending is carried out according to practical wiring mode, to adapt to the variation of installation site.Connecting tube is arranged to ripple
The structure of line section the problems such as can avoiding the occurrence of the flat deformation of connecting tube or bending deformation or even fracture, is effectively prevented because even
It takes over and fractures and cause happening for secondary refrigerant leakage, so as to achieve the purpose that protect connecting tube.
Although the structure of foregoing connecting tube effectively prevents the problem of connecting tube deforms, but since its structure is opposite
More complicated, relatively high to equipment and craftsmanship requirement during actual processing produces, process is also more various, system
Cause this big.Meanwhile when connecting tube is installed, although the characteristics of generally existing both ends stress is more slightly larger, installation difficulty is slightly higher than middle part,
But during practice of construction, one end of connecting tube is with after indoor unit or outdoor unit installation, installing the other end of connecting tube
When, the active force suffered by end first installed is substantially smaller, and the end only installed afterwards is just difficult to install, the end installed afterwards
The active force that portion is subject to also bigger, it is only necessary to connecting tube is arranged to one end and be relatively large in diameter, resulting in the prior art will be even
There are waste of material, high processing costs in the structure that the both ends diameter taken over is all provided with being set to than interlude diameter bigger.
Utility model content
The goal of the invention of the utility model is：Since the structure of reducing connecting tube of the prior art is both ends diameter
Greatly, interlude diameter is small, causes to there are problems that big manufacture difficulty, high processing costs, there are waste of materials, provides a kind of all-wave
Line connecting tube, the connecting tube are improved air conditioner connecting pipe according to actual installation demand, are meeting the feelings of performance requirement
Under condition, manufacture difficulty and processing cost can be reduced, while has saved material.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of full corrugated connecting tube, the full corrugated connecting tube is by the smaller path section of diameter and is arranged on the path section one
The major diameter section the being relatively large in diameter composition at end, the path section and major diameter section be an integral structure, and the path section and described big
Ripple is both provided in the section of footpath.Existing connecting pipe structure is big for both ends diameter, and interlude diameter is small, but is connected in actual installation
Guan Shi, the active force suffered by end first installed is substantially smaller, and the end only installed afterwards is just difficult to install, and installs afterwards
The active force that end is subject to also bigger, it is only necessary to connecting tube is arranged to one end and be relatively large in diameter, all-wave line of the invention connects
It takes over and path section and major diameter section is only set, in the fabrication process, to the of less demanding of process equipment, it is easier to meet processing technology
Requirement, greatly reduce manufacture difficulty, improve the work efficiency of operating personnel, reduce manufacture cost, while only one
It holds as major diameter section, has saved portion of material.When mounted, path section is first installed, then the major diameter section that installation difficulty is larger, it will even
The path section and major diameter section taken over are both provided with ripple, make it in connection procedure, achieve the purpose that protect connecting tube, make connection
Pipe meets performance, will not fracture there is a situation where connecting tube and cause secondary refrigerant leakage.
As the preferred embodiment of the utility model, changeover portion, the transition are provided between the path section and major diameter section
