[0002] At present, for the connection of relatively moving components with small size and circular cross-section, rubber hoses can be used to compensate; for the connection of relatively large-sized components with non-circular cross-sections, fasteners and rubber pads are generally used The way to connect, the compensation effect of this kind of connection is poor
Therefore, the existing connection method is not suitable for occasions where there are multi-directional relative movements between components and there is a need for sealing. For such special-shaped structural parts, it is necessary to design a new connection mechanism for connection

The invention discloses a connecting mechanism and connecting method for special-shaped structural members. The connecting mechanism comprises a member A, a member B and a rubber piece, wherein the inner surface size of the connecting section of the member A is slightly larger than the outer surface size of the connecting section of the member A, the connecting section of the member A is arrangedin the connecting section of the member B, and the rubber piece is arranged between the connecting section of the member A and the connecting section of the member B. The connecting method comprises the steps of inserting the connecting section of the member A into the connecting section of the member B, and achieving effective airtight connection between the member A and the member B through therubber piece. By adopting the connecting mechanism and the connecting method, the multi-direction relative movement between the two connecting members in the working process can be realized, and the connecting tightness can be met. The connecting structure and the connecting method are not only suitable for connecting members with large interface sizes and non-circular cross sections, but also suitable for connecting ports with any cross section, and have the advantages of the simple structure, installation convenience, safety and reliability.
Description
technical field [0001] The invention belongs to the technical field of connection between system design components, in particular to a connection mechanism and connection method for special-shaped structural parts. Background technique [0002] At present, for the connection of relatively moving components with small size and circular cross-section, rubber hoses can be used to compensate; for the connection of relatively large-sized components with non-circular cross-sections, fasteners and rubber pads are generally used The way to connect, the compensation effect of this kind of connection is poor. Therefore, the existing connection method is not suitable for occasions where there are multi-directional relative movements between components and there is a sealing requirement. For such special-shaped structural parts, it is necessary to design a new connection mechanism for connection. It is used for the connection of components that need to be sealed and there are multi-dir...
