背景技术Background technique
管路连接系统在工业中的诸多领域承担着重要的作用，传统的接头一般采用螺栓紧固的方式，其最大的缺点在于安装速度慢，装配时空间要求高，装配难度大，无法提高生产效率，另外，用螺栓紧固方式的结构，密封性和牢固性能都不是很理想。基于此，人们设计出了快速接头，但是，现有的快速接头只是可以将管路快速的连接起来，却“看”不见装配的是否到位，从而造成泄漏；并且，大多需要额外的部件，容易造成不必要的丢失，结构复杂，不易操作。The pipeline connection system plays an important role in many fields in the industry. The traditional joints are generally fastened by bolts. The biggest disadvantage is that the installation speed is slow, the space required for assembly is high, the assembly is difficult, and the production efficiency cannot be improved. , In addition, with the structure of the bolt fastening mode, the sealing and firm performance are not very ideal. Based on this, people have designed quick connectors, but the existing quick connectors can only quickly connect the pipelines, but can't "see" whether the assembly is in place, resulting in leakage; and most of them require additional parts, which are easy to Cause unnecessary loss, complex structure, difficult to operate.
