Abstract
The present invention is an anti-loosening flow nut for fixing to the bolt as an anti-loosening flow nut.
Bolts and nuts are widely used to couple mechanical elements to equipment and structures. The main role of nuts is to maintain the force in the bolt axis direction.
In particular, the coupling screw is designed to prevent self-release due to frictional force on the contact surface.However, when the vibration and shock are applied, the contact pressure decreases momentarily and the frictional force almost disappears.If this phenomenon is repeated, the screw is loosened and joined. The structure and the device is dismantled, so a large problem occurs to solve this problem is to provide an anti-loosening flow nut of the present invention.
The anti-loosening flow nut of the present invention cuts through the threaded portion 3 formed in the groove 2 from the half portion 7 of the hexagonal nut body 1 to the upper cut line 8 and simultaneously cuts the lower portion. Hexagon nut body (1) by cutting to the incision (9) is a loosening preventing flow nut, characterized in that it is structured in the form of a spring coil (4) to perform an excellent function
The anti-loosening flow nut of the present invention absorbs vibrations and impacts from the outside, and flows to the contact surface with the threads of the bolts coupled with the threads 3 formed in the grooves 2 so as to closely adhere to each other. And
The hexagon nut body (1) is made of a spring coil (4) in the form of a spring coil (4) and shrinks and expands in a spiral length while flowing to the upper incision line (8) or lower incision line (9) void while the thread (3) It is a structure that continuously performs the function that the nut does not loosen by increasing the contact pressure with the screw thread of the bolt.
In addition, the hexagon nut body (1) of the anti-loosening flow nut of the present invention generates a frictional force on the contact surface with the screw thread of the bolt coupled to the thread (3) without the left fastening screw or the right fastening screw tightly close contact pressure This is an anti-loosening flow nut characterized by providing a structure that gives an excellent function that the nut does not loosen.
Anti-loosening floating nut, spring coil (4), half part (7), hexagon nut body (1), excellent absorption of vibration and shock, strong friction force generated on the contact surface of the thread of the bolt coupled with the thread (3) Close contact, spring coil (4) in the form of a structure that continuously performs the function of flow, the nut does not loosen while shrinking and expanding to the length of the spiral by the temperature given from the outside,
Description
The present invention is an anti-loosening flow nut for fixing to the bolt as an anti-loosening flow nut.
Bolts and nuts are widely used to couple mechanical elements to equipment and structures. The main role of nuts is to maintain the force in the bolt axis direction.
Bolts and nuts, which are usually used as a means for conventional coupling,
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 momentarily and the friction force almost disappears.If this phenomenon is repeated, the screw is loosened and joined. There is a big disadvantage that structures and devices are dismantled, which causes great problems.
In addition, the conventional loosening prevention nut has a structure in which a spring is built in and a Teflon synthetic resin is combined in a 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. It is not safe from cracks when applying force. Also, the structure that combines Teflon resin has a big disadvantage that Teflon resin is crushed over a long period of time and loses its inherent function, resulting in large accidents.
The present invention eliminates possible eye elements in order to solve the above-mentioned conventional problems,
The hex nut body (1) of the anti-loosening flow nut is provided in the form of a spring coil (4) to absorb the vibrations and shocks from the outside so that the nut is not loosened. To provide
In addition, the loosening flow preventing nut of the present invention has a low manufacturing cost and is easy to combine, and is formed inside the groove 2 by flowing at a temperature while absorbing vibrations and shocks from the outside when the objects are combined. The purpose of this invention is to provide a loosening nut for preventing loosening, characterized in that the frictional force is strongly generated on the contact surface of the bolt coupled with the screw thread (3), and the contact pressure is increased to give a safe function to prevent the nut from loosening.
The anti-loosening flow nut of the present invention cuts through the threaded
The anti-loosening flow nut of the present invention has an advantage that the hexagon nut body 1 is made of a
The hexagon nut body (1) has a spring coil (4) shape and flows while contracting and expanding in a spiral length by the temperature given from the outside, and the contact pressure with the thread of the bolt coupled with the thread (3) is increased to release the nut. Advantages are anti-loosening floating nuts, characterized by excellent performance not to lose
In addition, the loosening prevention nut of the present invention is formed in the form of a spring coil (4), regardless of whether the tightening screw to the right or the tightening screw to the left
There is an advantage to provide the anti-loosening flow nut of the present invention excellent in the safe coupling of the object by tightening the fastening-fastening flow nut tightening screw fastened to be fixed.
In addition, the anti-loosening flow nut of the present invention eliminates the spring or Teflon synthetic resin coating incorporated in the conventional anti-loosening nut and provides a loosening nut with excellent function while simplifying the structure, thereby greatly reducing manufacturing and construction costs. There is this
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
