Description

Flexible fastener construction with multiple snap-fit configurations

The invention relates to a multi-fastening type flexible fastener which can be assembled according to the requirements of different butt pipelines during production and manufacture.

At present, the pipeline for transporting fluid or gas is generally used. At each end of the pipeline that is connected to each section, a flange is respectively arranged, so that the flanges at the two ends of the pipeline are aligned with each other and reused. After the plurality of screws are passed through the flange, a nut is screwed in, so that the two pipes can be tightly joined to prevent leakage and danger, and the length of the pipe conveying path can be extended. However, since the mounting flanges must be symmetrically locked with a plurality of screws, they are quite cumbersome, time consuming, and relatively bulky and heavy in assembly or disassembly, which is inconsistent with work efficiency.
