Description

Technical Field

[0001] The utility model relates to the technical field of supporting structures, in particular to a vacuum bellows retaining frame. Background Art

[0002] A vacuum bellows is an axisymmetric tubular shell with a corrugated busbar and a certain degree of bendability, so it is also called a flexible tube or a flexible tube. Due to the characteristics of its geometric shape, the bellows can change its axial length under the action of pressure, axial force, lateral force, and bending moment. The length of the bellows is extended under the action of tensile force; the length of the bellows is shortened under the action of compression force. The difference between it and a bare tube (plate tube) is that in addition to having a certain strength and rigidity, it also has greater flexibility and high fatigue resistance, which makes the bellows have a very wide range of applications.

[0003] During the assembly process of the vacuum bellows, in order to ensure the stable connection of the end portion when bending and changing in length, the end portion of the vacuum bellows needs to be fixed and retained. However, the traditional fixing and retaining method generally directly uses a fixing ring for clamping, and the structural dimensions are fixed, which makes it difficult to adapt to the assembly of vacuum bellows of different sizes. For this reason, the present application proposes a vacuum bellows retainer. Utility Model Content
