The small hard lock nut represents the spirit of unremitting efforts of domestic scientific research workers

By the end of 2019, the total mileage of my country's high-speed rail has exceeded 35,000 kilometers, building the world's most developed high-speed rail network. However, for a long time, the vibration caused by high-speed railway running on the track has a great influence on the stability of parts and components, and it also directly threatens the safety of trains. Therefore, the non-moving parts made of hard lock nuts also play a vital role in the safety of high-speed rail. Before, everyone would question how there is a nut that never moves. In this regard, our country has also conducted experiments with hard lock nuts, and found that this kind of nut, which is called never moving, does have very powerful performance. Therefore, hard lock nuts will be widely used in my country's high-speed rail field.

Our country has long been known as a global factory, and the products manufactured in our country have gone through years of unremitting efforts, from the previous impression of low cost and low quality to the image of high quality and low price. Today's my country's manufacturing industry has won a global reputation and won wide acclaim and honors from many countries. my country's manufacturing industry has experienced setbacks and challenges again and again. In fact, for our country, a small nut can be overcome sooner or later.

In recent years, with the continuous improvement of my country's economic strength and science and technology, especially the continuous acceleration of high-speed railway network construction, the key component of the never-moving nut has become the top priority of my country's manufacturing industry. After 10 years of research and hard work by scientists and technicians, this model was eventually declared by Japan as "a nut that can never be replicated" or was broken by China. It is reported that the nuts produced in my country are even better than those produced by Japanese companies, further breaking the record held by Japanese nuts. This kind of anti-loosening component, called "Tang nut", uses two kinds of nuts with different rotation directions to change the thrust force into the tightening force. When using, tighten the fastening nut first, and then tighten the lock nut. When the fastening nut slides, the locking nut can prevent the fastening nut from loosening in time, thereby ensuring the stability of the fastening nut.

In fact, a small hard lock nut also represents the unremitting efforts of many domestic scientific researchers. For a long time, due to the technological blockade of our country by Europe, America and other countries, our country has had to rely on its own independent research and hard manufacturing in the field of scientific and technological manufacturing. Without the hard work of many scientific and technological workers, the current manufacturing level still cannot reach such a high level.

Of course, objectively speaking, my country's current manufacturing level still has a certain gap with the global advanced level in many aspects. The spirit of continuous improvement of product quality and continuous innovation embodied by Japanese companies is also worth learning from Chinese companies. Therefore, the future development of the manufacturing industry still has a long way to go in Renzhong. Only through unremitting efforts can the country's technological level and the development of the manufacturing industry be in the forefront of the world.
