CONSTITUTION: An anti-releasing square spring nut is fixed to a bolt. The anti-releasing square spring nut cut passing through the thread(3) of a groove(2) from the half part of the nut(1), to an upper cutting line(8) and to a lower cutting line(9), thus the spring nut is formed in a spring coil(4) form.

Description

Loosening Square Spring Nuts {omitted}

The present invention is an anti-loosening floating nut for fixing to a bolt as a anti-loosening square spring 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. Not safe from cracks when applying force

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,

The anti-loosening square spring nut provides a rectangular nut body (1) of the anti-loosening square spring nut in the form of a spring coil (4) to absorb the vibrations and shocks from the outside to give a safe function to prevent the nut from loosening. To provide a nut

In addition, the anti-loosening square spring nut of the present invention has a low manufacturing cost and is easy to combine.

Friction force is generated strongly on the contact surface with the thread of the bolt that is coupled to the thread (3) formed in the groove (2) by absorbing the vibration and shock from the outside to the temperature, and close contact

This is to provide a release preventing square spring nut, which is characterized by the fact that the contact pressure is increased to give the nut a safe function.

The anti-loosening square spring nut of the present invention cuts through the thread 3 formed in the groove 2 in the half portion 7 of the square nut body 1.

Cut to the upper incision line (8) and at the same time to the lower incision line (9) to provide a square nut body (1) structured in the form of a spring coil (4).

Anti-loosening square spring nut of the present invention has the advantage that the square nut body (1) in the form of a spring coil (4) to excellently absorb the vibration and shock given from the outside.

The square nut body (1) is made of a spring coil (4) and flows while shrinking 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 square spring nuts, characterized by excellent performance without loosening

In addition, the anti-loosening square spring 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

It is advantageous to provide the anti-loosening square spring nut of the present invention which is secured more securely by tightening the anti-loosening square spring nut fastened to be fixed.

In addition, the anti-loosening square spring nut of the present invention eliminates the spring or Teflon synthetic resin coating, which is incorporated in the conventional anti-loosening nut, and provides a simplistic structure while providing excellent anti-loosening square spring nut, thereby greatly improving manufacturing and construction cost. Has the advantage of lowering

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

"In detail, it looks like this"

The present invention is an anti-loosening square spring nut for fixing to a bolt as an anti-loosing square 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 momentarily and the friction force almost disappears.If this phenomenon is repeated, the screw is loosened and joined. Since the structure and the device are dismantled, a large problem occurs, and thus, the present invention provides an anti-loosening rectangular spring nut for solving such a problem.

The anti-loosening square spring nut of the present invention cuts through the threaded portion 3 formed in the groove 2 from the half portion 7 of the square nut body 1 and cuts to the upper incision line 8 at the same time. The square nut body 1 is cut in the form of a spring coil 4 by cutting to the lower incision line 9.

The anti-loosening square spring nut of the present invention has a strong friction force on the contact surface of the thread of the bolt coupled to the thread (3) formed in the groove (2) by flowing while absorbing the vibration and shock from the outside excellently It is in close contact with the rectangular nut body (1) is formed in the form of a spring coil (4) shrinks and expands to the length of the spiral by the temperature given from the outside while flowing up to the gap in the upper incision line (8) or lower incision line (9) and the thread ( 3) It is a structure that continuously and excellently performs the function that the nut does not loosen by increasing the contact pressure with the screw thread of the bolt.

In addition, the square nut body (1) of the anti-loosening square spring 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) regardless of whether the left tightening screw or the right tightening screw is tightly contacted. Anti-loosening square spring nut, characterized in that the structure is provided to give an excellent function to prevent the nut from loosening due to the increased pressure.

Regardless of the shape of the nut body, such as the square nut body (1), the round nut, and the butterfly nut type, the present invention is structured in the form of a spring coil (4) on the square nut body (1) and coupled with a bolt. In order to move the square nut body (1) structured in the form of a spring coil (4) by the external pressure or temperature tightening the square nut body (1), the position of the thread (3) is changed so that the nut (3) of the nut is bolted. It is included in the claims of the present invention that the tightly coupled to the thread of the screw is added to the loosening prevention function
