Abstract

PURPOSE: A loosening prevention nut forming a screw thread by obliquely passing through is provided to enhance a loosening prevention function of bolts when joining a structure and to stabilize the structure. CONSTITUTION: A loosening prevention nut forming a screw thread by obliquely passing through comprises a nut body(2). A through-hole(1) is obliquely formed around a central part of the nut body at an angle of 0.001 degree to 60 degree and a screw thread(3) is formed in the inner side of the through-hole. If the nut is loosened over than a half cycle from a right position where the nut is fastened, the nut body becomes inclined as much as the angle in which the through-hole is inclined so that the inclined nut body is easily checked out with the unaided eye.

Description

Loosen nut, threaded through perforation at oblique angle

The present invention is an anti-loosening nut formed by threading through a beveled angle. Bolts and nuts are widely used for joining devices and structures or mechanical elements, and the main role of the bolts is to prevent the bolts and nuts fastened to the joined structure from being loosened. To keep

In general, bolts, nuts and washers used as a means for conventional coupling are designed to prevent self-release due to frictional force generated at the mating contact surface, but when the vibration and shock are applied, the contact pressure decreases instantaneously and the frictional force almost disappears. If this phenomenon is repeated, the bolts are loosened and the combined structures and devices are dismantled.

In addition, the nut, which has a general pulley prevention function, has a large disadvantage in that the structure is complicated and the manufacturing cost and the selling cost are high.

The present invention eliminates possible eye elements in order to solve the above-mentioned conventional problems,

The present invention is to provide a loosening nut formed by threading through a beveled angle to prevent the bolts and nuts from loosening by lightly deriving the structure while the cost cost is small to combine the structure that is not loosened by vibration. For sake

The anti-loosening nut formed by threading through the oblique angle of the present invention is a through hole (1) at an oblique angle of 60 degrees or less at an angle of 0.001 degrees or more, based on the center of the nut body (2), and a screw thread (3) inside the through hole (1). Shaping

Produces and provides an anti-loosening nut that is threaded through the oblique angle.

The present invention provides a nut that prevents loosening through a bevel angle to form a thread

When joining the structure, the bolt and bolt's loosening prevention function is excellent and the stability of the structure is excellent.

In addition, the structure is simpler than the conventional spring-embedded bolts or anti-locking bolts, the manufacturing cost is significantly reduced, lighter, and the tightening is simpler.

In addition, the anti-loosening nut formed by the threaded hole (3) by the oblique angle (1) is loosened more than half a turn at the exact position where the nut is tightened, the nut body (2) is inclined much by the angle given to the through hole (1) easily with the naked eye. It is confirmed that it has the advantage of preventing safety accidents.

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

1 is a structural diagram schematically illustrating an anti-loosening nut through which a thread is formed through the oblique angle according to the present invention.

The anti-loosening nut formed by threading through the oblique angle of the present invention is a through hole (1) at an oblique angle of 60 degrees or less at an angle of 0.001 degrees or more, based on the center of the nut body (2), and a screw thread (3) inside the through hole (1). Will form

Thread (3) formed inside the through hole (1) at an oblique angle of 60 degrees or less at the angle of 0.001 degrees or more, by inserting the bolt into the member and tightly tightened with a tool, the friction between the screw thread of the bolt and the thread of the nut Making the cotton bigger

Like lifting the bolt shaft to the lever, the force of vibration is transferred to the eccentric load, leading to a more powerful wedge action, thereby preventing the loosening function.

In addition, the structure is simpler than conventional spring-embedded bolts or anti-locking bolts, so the manufacturing cost is greatly reduced, lighter, and concise.

In addition, the anti-loosening nut formed by the threaded hole (3) by the oblique angle (1) is loosened more than half a turn at the exact position where the nut is tightened, the nut body (2) is inclined much by the angle given to the through hole (1) easily with the naked eye. It is confirmed and prevents safety accidents

In addition, the anti-loosening nut formed by threading through the oblique angle of the present invention is hexagonal, pentagonal, octagonal, square, circular, butterfly nut, flange nut, other special nuts

It is made by forming a through hole (1) at a comb angle of more than 60 degrees from an angle of 0.001 degrees or more with respect to the center of the nut body (2) and forming a screw thread (3) inside the through hole (1).

Figure 1 is a schematic structural view of the anti-loosening nut formed through the threaded through the oblique angle in accordance with the present invention
