Anti-loosening screw technology "Good-resistant" anti-loosing screw technology

Screws are a common term for fasteners, a daily spoken word. Screws are indispensable industrial necessities in daily life: such as very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws are used , Nuts; transportation equipment, airplanes, trams, cars, etc. are used for both large and small screws. Screws have important tasks in industry. As long as there is industry on the earth, the function of screws is important.

　　 Screw loosening has always been a serious problem in industrial manufacturing and industrial products, and even a fatal hidden danger. This accidental accident has caused unpredictable harm to our daily life, work, transportation, national defense and military. Therefore, engineers and scientists from all over the world have put into in-depth research on screw anti-loosening for a long time, praying for a solution.

The anti-loose and drop-resistant screw was invented in the United States more than 30 years ago. The anti-loose and drop-resistant screw is a special technology to attach special engineering plastics to the threads, so that the engineering plastics are squeezed during the locking process of the internal and external threads. It produces a strong reaction force, which better increases the friction between the internal and external threads, and provides resistance to vibration. The anti-loosening and anti-dropping screws provide this resistance, which is completely distributed throughout the meshing section of the internal and external threads. It has nothing to do with the locking pressure between the internal and external threads. Once the anti-loosening and anti-falling screws are locked in, the friction force is generated and existing immediately. Even if the anti-loosing and anti-falling screws are not locked, they will not loosen, which is different from the previous stopping methods. , Relying on the friction force generated by the pressure after the screw is locked to stop the retreat. Once the screw is slightly loosened and the pressure is reduced, the friction quickly disappears and loses the retreat effect, causing the screw to loosen.

　　 Because this special engineering plastic on the anti-loose and drop-proof screw has strong elasticity and memory ability, the anti-loose and drop-proof screw can be disassembled repeatedly 5 to 50 times, and the anti-loose function of the anti-loose and drop screw still exists. Because this kind of anti-loose engineering plastic is environmentally friendly, lightweight, and reproducible, it has become a more reliable anti-loose and drop-resistant screw product today. Moreover, the special engineering resin on the anti-loose and drop-resistant screws has the advantage of very high chemical stability, is resistant to acids, alkalis, and other solvents, and will not cause oxidation and corrosion to metals, so the anti-loose and drop-resistant screws will not rust, The peeling phenomenon of the electroplating film contributes to the requirements of product lightweight, weather resistance and quality. This special engineering plastic-commonly known as anti-falling glue, is suitable for bolts and nuts of various shapes and various metal materials as an anti-loosening treatment. Screws that have undergone anti-loosening treatment are called anti-loose and drop-proof screws, which are suitable for the fastening of moving parts. Anti-loose and drop-proof screws were used in American aerospace aircraft as early as, and later anti-loose and drop screws were promoted to the American automobile manufacturing industry. With the maturity of manufacturing technology and the reduction of cost, anti-loose and drop-resistant screws are widely used in 3C, bicycles, skating and ski equipment, furniture, sports equipment, medical equipment and other industries, replacing traditional non-return washers, which fully demonstrates The reliability of the anti-loosening and anti-loosening screw tightening and anti-loosening effect.
