The quality of a fastener screw from a hardware fastener manufacturer provides more than just fasten
A stainless steel screw manufacturer's anti-loosening screw provides not only tightening, but also a guarantee of safety! A murder caused by a screw? Let us first look at these examples.
On January 31, 2000, Alaska Airlines Flight 261 crashed due to a fatal problem with the retractable screw nut of the rear wing level of tranquility. At the time, all 88 people (including 3 children) were killed. In March 2008, a Boeing 757 airliner of American Airlines performed a frightening moment over the Atlantic Ocean: A screw loosened, causing the heater in the cockpit to catch fire, and there were several cracks on the windshield. The aircraft slammed down. Fortunately, it did not happen. Casualties.
At 16:45 on June 29, 2010, the "Space Trek" amusement project in the Grand Canyon in the eastern Chinese city of Shenzhen collapsed in a safety accident, resulting in 6 deaths and 10 injuries, of which 5 were slightly injured, forming the secondary cause of the accident A 16mm screw is loose and damaged.
At about 1 p.m. on September 13, 2012, a serious accident occurred at a construction site at the junction of Wuhan Yangtze River Erqi Bridge and Happy Trail. A construction lift fell from the 30th floor, resulting in the unfortunate death of 19 people. It is preliminarily determined that the accident was caused by the overload of the elevator and the loosening of the elevator screws.
In the event of a safety accident, a hardware and electrical screw can determine life and death. Regarding the brand and the product, the details are extremely fatal. Tomorrow, Mr. Speed will talk to you about the unknown details on the car special screws.
For mid-drive power-assisted bicycles, the most central component is the mid-mounted motor located at the bottom of the body. Affected by the status of the device, the mid-mounted motor not only needs to accept the impact of external forces such as soil and flying rocks, but also the vibration of the motor during its operation. Therefore, the central motor has higher requirements for protection and stability. Secrets in the screw Interpreting the details of the devil of the double-speed travel booster bicycle
A shield can be added to improve the protection, but it is necessary to use some special wrists for the external stability of the motor. Because the high-speed electrical timing is affected by the pedaling force, high-frequency vibration, temperature fluctuation and other factors, how to avoid the screw loosening. This solves a major problem in the assembly process of mid-mounted motors. At the beginning of the design, the engineer chose high-quality anti-drop screws, but the rubber material for the anti-drop screws is very complicated. If you can't choose the right rubber, it will be difficult to produce satisfactory results.
After several twists and turns, Speed Travel found Nailuo Group. The anti-falling screw is known as the best screw-proof product in the world, and even the space shuttle uses it to stop reinforcement. According to the introduction, the anti-falling screw is sprayed with a patented engineering resin on the surface of the fastener. During the locking process, the engineering resin is squeezed to produce a weak reaction force, thereby increasing the friction between the threads and preventing the screw from loosening. Specially formulated engineering resin is added to the screw thread, which can prevent the screw from falling out and extend the service life of the screw. Dexin hardware fastener manufacturers provide us not only fastening, but also a guarantee of life and safety.
