The poor problem of bendability.
To achieve the goals above, the technical proposal of the invention is realized in this way：
A kind of scalable flexible vacuum pipe, including bellows, welding point, connection weld-ring, elastic element and
Metal net cover, the bellows both ends are connected with the welding point respectively, the metal net cover both ends respectively with the elasticity
Element is respectively connected with, and the metal net cover and elastic element are respectively sleeved at the bellows periphery, described connection weld-ring one end
It is connected with welding point, the connection weld-ring other end is connected with elastic element.
Preferably, the metal net cover is stainless steel net cover.
Preferably, the connection weld-ring is connected with elastic element by being welded and fixed.
Preferably, the elastic element is the roll type spring that every circle has identical form diameter.
Preferably, connection the distance between the weld-ring and the metal net cover are less than or equal to freely growing for the spring
Degree, the spring are resisted against on connection one side end of weld-ring far from one end of the metal net cover, one side of connection weld-ring
The anti-drop device for preventing the spring with connecting weld-ring disengaging is additionally provided in portion.
Preferably, the anti-drop device is two circles from prolonging far from the metal net cover to the direction close to the metal net cover
The flanging stretched, the spring are set between two circle flangings far from the end of metal net cover side.
Preferably, the two circles flanging coaxial arrangement.
Present invention tool has the advantage that：
Connection weldering is arranged in scalable flexible vacuum pipe proposed by the present invention between welding point and metal net cover
Ring and elastic element, elastic element not only can stretch but also can be bent, and enhance scalability and the flexible of vacuum pipe,
Elastic element and metal net cover are set in bellows periphery, it is therefore prevented that bellows expansion explosion.Compared with prior art, the present invention mentions
Scalable flexible vacuum pipe out has the advantages that telescopicing performance is good and good bending property.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the semi-cutaway of the embodiment of the present invention 1；
Fig. 2 is the semi-cutaway of the embodiment of the present invention 2.
In figure：1- bellows, 2- welding point, 3- connection weld-ring, 4- elastic element, 5- metal net cover, 31- anticreep dress
It sets.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor
Embodiment shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, the scalable flexible vacuum pipe of one kind proposed by the present invention, including bellows 1, weldering
Connector 2, connection weld-ring 3, elastic element 4 and metal net cover 5,1 both ends of bellows are connected with welding point 2 respectively, metal
5 both ends of net cover are respectively connected with elastic element 4 respectively, and metal net cover 5 and elastic element 4 are respectively sleeved at 1 periphery of bellows, even
It connects 3 one end of weld-ring to be connected with welding point 2, connection 3 other end of weld-ring is connected with elastic element 4.Metal net cover 5 is stainless (steel) wire
Set.
As shown in Figure 1, connection weld-ring 3 is connected with elastic element 4 by being welded and fixed in embodiment 1.In this way in vacuum tube
In flexible or bending, elastic element 4 is just moved with the movement of the bellows 1 of inside accordingly in road.
