Description
The present invention is a loosening spring-loaded spring nut
Nuts are widely used to couple mechanical elements to machines and structures. The main role of nuts is to maintain the force in the bolt axis direction.
In general, bolts and nuts used as a means of conventional coupling are designed so that the coupling screw does not loosen itself due to friction on the contact surface.However, when the vibration and shock are applied, the contact pressure decreases momentarily and the friction force is almost lost. Phenomenon occurs and if this phenomenon is repeated, the screw is loosened and the combined structure and the device are dismantled.
In addition, if you look at the conventional anti-loosening nut, there is a structure that combines the built-in spring and the Teflon synthetic resin inside the nut groove, but this structure is complicated and the manufacturing cost is high and the spring contact surface is damaged when subjected to repeated external vibration. The disadvantage is that it is not safe from cracking when
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.
In addition, there is a big disadvantage in that the nut assembled in the frictional heat of vibration is easily loosened.
The present invention eliminates the inner element as far as possible to solve the above-mentioned conventional problems, and forms a thread (3) through the inside of the groove (2) of the nut body (1)
The nut body (1) is cut from the proximal end of the nut (8) to the proximal part of the nut upper part (7) of the nut body (1) along the incision line (6), and cut in a winding shape.
It cuts through the lower surface of the nut (8) from the thread (3) inside the groove (2) to softly absorb vertical vibration, horizontal vibration, high frequency vibration and low frequency vibration.
The purpose of this invention is to provide an anti-loosening spring-loaded nut, which is characterized by preventing elasticity by maximizing the frictional force of the bolt and nut thread coupled by generating elasticity by flowing at temperature.
The present invention as a spring-loaded spring nut
Through the inside of the groove (2) of the nut body (1) to form a thread (3)
The nut body (1) is cut from the proximal end of the nut (8) to the proximal part of the nut upper part (7) of the nut body (1) along the incision line (6), and cut in a winding shape.
It cuts through the lower surface of the nut (8) from the thread (3) inside the groove (2) to softly absorb vertical vibration, horizontal vibration, high frequency vibration and low frequency vibration.
It provides an anti-loosing spring-type nut, which flows in temperature and generates elasticity to prevent loosening by maximizing the frictional force between the bolt and the nut thread.
Anti-loosening spring-type nut of the present invention is coupled to the thread (3) formed inside the groove (2) by flowing with high elasticity while presenting a spring structure to absorb the vibration, shock and temperature changes given from the outside excellently It has the advantage of continuously providing a safe function that the nut does not loosen by strongly generating friction force on the contact surface of the bolt with the thread.
In addition, the anti-loosening spiral flow nut of the present invention eliminates the internal spring or Teflon synthetic resin coating incorporated in the conventional anti-loosening nut and provides a loose anti-loosening spiral flow nut with excellent function while simplifying the construction and construction cost. There is a significant lowering advantage
In addition, the vibration is canceled and on the one hand, the vibration direction is changed to generate tension and maximize elasticity and frictional force.
In addition, there is an advantage to provide the anti-loosening spring-loaded nut of the present invention to excellently cancel the high frequency vibration, low frequency vibration
In addition, it has a structure in which atmospheric air is freely distributed between the
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As specifically illustrated below, as shown in FIG. 1 is a perspective view showing a loosening spring-loaded nut in accordance with the present invention.
The present invention is to be fixed to the bolt as a loosening spring-loaded spring nut
In particular, the coupling screw is designed to prevent self-release due to friction on the contact surface. However, when the vibration and shock are applied, the contact pressure decreases instantaneously and almost no friction occurs.
If this phenomenon is repeated, the screw is loosened and the combined structure and the device are dismantled so that a large problem occurs. Thus, the anti-loosening spiral flow nut of the present invention is provided to solve such a problem.

On the other hand, the loosening spring-loaded nut is characterized in that it prevents loosening by maximizing the frictional force between the bolt and nut screw thread which is generated by elasticity.
