Description
Technical field
The present invention relates to air-conditioning technical field, more particularly to a kind of shock absorbing pipe and the air conditioner with the shock absorbing pipe.
Background technology
The application of current convertible frequency air-conditioner is more and more extensive, with the lifting of air-conditioning converter technique, the running frequency of compressor
Scope is more and more wider, and the Oscillation Amplitude of pipe arrangement increases therewith, causes the vibration stress on pipe arrangement to exceed limit value, influence air-conditioning
Normal operation.To solve the problem, can connect shock absorbing pipe in air conditioner piping in the prior art.Shock absorbing pipe generally comprises ripple
Pipe and net, bellows stiffness are smaller, are easily deformed upon under ambient pressure effect, and net is wrapped in into the outer of bellows
Portion, to limit the deformation quantity of bellows and then form mechanical protection to bellows.However, there is following defect in net：
1st, net is typically formed by braided steel wire, and steel wire is in tensioned state during pressure-bearing inside shock absorbing pipe, braiding structure
There is larger contact and frictional force between levels steel wire, the flexibility of shock absorbing pipe can be significantly reduced, influence shock absorbing pipe
Damping effect；
2nd, shock absorbing pipe bending or when vibrating, net and bellows contact with each other and can cause the abrasion of bellows, in addition, outside
Mechanical shock also indenture in bellows surface can be left by net, cause the mechanical strength of bellows to decline so that shock-absorbing
The service life of pipe shortens.
The content of the invention
The main object of the present invention is to provide a kind of shock absorbing pipe, it is intended to realize preferable shock-proof effect while having longer make
Use the life-span.
To achieve the above object, shock absorbing pipe proposed by the present invention, including bellows and it is connected to the bellows two
First connection ring and the second connection ring at end, the shock absorbing pipe also include at least two flexible strands, one end of each flexible strand
