Description
The present invention relates to a helical loosening nut, and more particularly to bolts and nuts, which are widely used for coupling mechanical elements to machines and structures, and to anti-loosening nuts due to vibration.
In general, bolts and nuts used as a means of conventional coupling are designed to prevent self-release due to frictional force generated on the mating screw contact surface, but the contact force decreases momentarily when subjected to vibrations and shocks, and the frictional force almost disappears. If this phenomenon is repeated, the screws are loosened and the combined structures and devices are dismantled, which causes a great problem.
In addition, the conventional loosening nut has been constructed by inserting a spring into the nut groove, but this structure is complicated, the manufacturing cost is high, and the contact surface is damaged when subjected to repeated external vibration.
In addition, the structure of combining Teflon synthetic resin has a big disadvantage that Teflon synthetic resin is distorted after long-term use and loses its inherent function, resulting in large-scale accidents.
The present invention eliminates possible eye elements in order to solve the above-mentioned conventional problems,
Spiral loosening nut of the present invention is easy to combine with a low manufacturing cost
In addition, when an object is combined, it flows while absorbing vibrations and shocks from the outside and generates a frictional force on the contact surface of the bolt thread coupled with the
It is to provide a helical loosening nut, which is characterized by providing a safe function that the nut does not loosen by increasing tension and contact pressure.
The helical loosening nut of the present invention is a screw thread (3) formed in the groove (2) in the form of a helical inclination angle starting from the nut body lower surface (5) of the nut body (1) to the nut body upper surface (6). The nut body (1) of the helical loosening nut is made in the form of a spiral spring coil (4) so as to absorb vibrations and shocks from the outside, and excellent in tension while flowing and formed inside the groove (2). The helical loosening nut of the present invention is characterized by a structure in which a friction force is strongly generated on the contact surface of the bolt coupled with the
