Element is respectively connected with, and the metal net cover and flexible member 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 flexible member.
It is preferred that, the metal net cover is stainless steel net.
It is preferred that, the connection weld-ring is connected with flexible member by being welded and fixed.
It is preferred that, the flexible member is often roll type spring of the circle with identical form diameter.
It is preferred that, the connection weld-ring and the distance between the metal net cover are freely long less than or equal to the spring
Degree, the one end of the spring away from the metal net cover is resisted against on the connection side end of weld-ring one, the connection side of weld-ring one
The anti-drop device for preventing the spring with being connected weld-ring disengaging is additionally provided with portion.
It is preferred that, the anti-drop device is two circles from prolonging away from the metal net cover to the direction close to the metal net cover
The flanging stretched, end of the spring away from metal net cover side is between two circle flangings.
It is preferred that, the two circle flangings are coaxially disposed.
The utility model tool has the advantage that：
The utility model proposes scalable flexible vacuum pipe between welding point and metal net cover the company of setting
Weld-ring and flexible member are connect, flexible member not only can stretch but also can bend, and enhance the scalability and bendable of vacuum pipe
Qu Xing, flexible member and metal net cover are set in bellows periphery, it is therefore prevented that bellows expansion bursts.Compared with prior art, originally
The scalable flexible vacuum pipe that utility model is proposed has the advantages that telescopicing performance is good and good bending property.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belongs to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model proposes a kind of scalable flexible vacuum pipe, including bellows
1st, welding point 2, connection weld-ring 3, flexible member 4 and metal net cover 5, the two ends of bellows 1 are connected with welding point 2 respectively,
The two ends of metal net cover 5 are respectively connected with flexible member 4 respectively, and metal net cover 5 and flexible member 4 are respectively sleeved at outside bellows 1
Week, connection one end of weld-ring 3 is connected with welding point 2, and the connection other end of weld-ring 3 is connected with flexible member 4.Metal net cover 5 is not
Become rusty steel mesh set.
As shown in figure 1, in embodiment 1, connection weld-ring 3 is connected with flexible member 4 by being welded and fixed.So in vacuum tube
