Description

Soft and hard bi-polar connection structure of stable connection Technical Field The utility model belongs to the field of joint manufacturing, and particularly relates to a soft and hard double-end connecting structure for stable connection. Background In various fluid delivery systems, the performance of the water connection joint as a key component directly influences the operation effect of the whole system. The traditional water pipe connection joint has various forms, and common welding, threaded connection, clamp connection and the like. Under the general static and stable environment, the connectors can meet the basic connection and sealing requirements, and ensure that the water pipe system normally conveys fluid media such as water. However, as engineering application scenarios become increasingly complex, existing connection joints expose a number of problems. In connection scenarios involving switching of rigid and flexible pipes, existing joints do not provide a good way of adaptation. Hard tubes are hard in texture and stable in shape, while flexible tubes have flexibility and bendability, which differ greatly in physical properties. The common joint is difficult to ensure sealing, and simultaneously, the rigid connection requirement of the hard pipe and the flexible adaptation of the hose are considered, so that the joint is easy to leak, and the normal operation of the system is influenced. The lack of stability is also a major drawback of the existing connection joints. Particularly in areas where earthquakes are frequent, intense vibrations can subject the pipe system to continuous and complex stresses. Under such a vibration environment, it is difficult to ensure stable connection with conventional connection joints. The joint is likely to loosen, displace and even fall off due to vibration, so that the water pipe is broken, serious water disaster is caused, water resource waste is caused, damage to surrounding building structures, electrical equipment and the like is also likely to be caused, and huge threat is brought to life and property safety of people. For joints provided with grounding bolts, the existing designs do not guarantee sufficient strength. In some places where electrical safety is required, such as in the chemical and electronic industries, the water pipe system needs to be grounded by a grounding bolt to conduct static electricity or to be a part of a grounding circuit of the electrical equipment. However, in actual working conditions, when the pipeline bears the influence of internal fluid pressure, external mechanical stress and possible vibration, the grounding bolt is often broken or deformed due to insufficient strength, so that the effectiveness of grounding is damaged, the electrical safety standard cannot be met, and the potential safety risk is increased.
