What is the tolerance range of precision screws?
Nuts on the market still have certain defects. The bolts rely on multiple nuts against each other to prevent loosening. This method cannot be completely locked. The bolts are easily loosened when subjected to huge pressure and vibration, which hides potential safety hazards and has a protective effect. Bad problem, for this, we propose a nut with self-locking function
The traditional dismantling of automobile girder rivets is mostly carried out manually, which has many defects such as long disassembly time, low disassembly efficiency, labor-intensive, time-consuming, labor-intensive, low operation safety, difficult protection, and easy injury.
At present, more rivets are used on car tires. Due to the long-term bumps of the car, traditional equipment is prone to loosening during the use process, which affects safety. The above problems need to be improved on traditional equipment, so how to design a Rivets on car tires, this becomes a problem we need to solve.
safety screw includes a screw rod, and is characterized in that: the two ends of the screw rod are respectively provided with notches for rotating a tool knife. Compared with the prior art, the advantage of Guangdong Yueluo Hardware Industry Co., Ltd. is that notches are provided at both ends of the screw, so that when the screw is in use, it can be tightened or loosened from both ends without installation. Due to the limitation of position and structure, when the installation space is small or the tool knife cannot be inserted, it is convenient for the operator to directly tighten or loosen the screw from the other end, which improves the efficiency of installation and disassembly, saves assembly time and reduces assembly difficulty.
