Bolts each having a plurality of resin receiving grooves formed at equal intervals along the circumference of the pin to communicate with each other; And a circumference is formed in an angular shape, and a through hole is formed at a central portion thereof in a diameter through which the pin portion of the bolt can pass. A thread is formed on the side wall of the through hole to a size corresponding to the thread of the bolt. It includes a nut each formed with a plurality of resin receiving grooves at equal intervals along the inner wall circumference of the through-hole so as to pass in the vertical direction.

In another aspect, both objects are passed through the bolt, and the nut is fastened on the back surface thereof, the molten resin is poured through the contact portion of the bolt and the nut, and then dried to dry the thread of the bolt and the thread of the nut. As the gap between the resin receiving grooves of the bolt, the resin receiving grooves of the nut are respectively solidified to fasten the two objects.

The present invention fills the resin receiving groove of the bolt and the resin receiving groove of the nut while the molten resin moves through the gap between the thread of the bolt and the nut of the nut by tightening the molten resin after tightening the bolt and nut between the two objects. After a certain period of time, the molten resin is hardened so that the bolt and nut are firmly held together so that the bolt and nut are not separated from each other, so that the bolt-nut structure is not separated even if any external force is generated, thereby ensuring safety.

2 is a cross-sectional view of the bolt-nut structure in accordance with the present invention.
Figure 3 is a flow chart when fastening the object using the bolt-nut structure according to the invention.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the attached drawings.

The present invention is to more firmly fasten both objects using a bolt-nut structure.

The bolt 10 applied to the present invention has a general shape in which a thread 13 is formed at the tip of the pin portion 12 while being composed of an angled head portion 11 and a pin portion 12 fixed integrally with the central portion thereof. A bolt is applied to the plurality of resin receiving grooves at equal intervals along the circumference of the pin portion 12 so as to pass from the distal end portion of the pin portion 12 to the head portion 11 in the thread 13 of the bolt 10. 14) are formed respectively.

The resin receiving groove 14 of the bolt 10 may be configured such that its position varies depending on the pitch, but each of the resin receiving grooves 14 passes from the distal end portion of the pin portion 12 in the direction of the head portion 11 in consideration of manufacturing convenience. Each pitch is formed at the same position.

The nut 20 applied to the present invention has a circumferentially angular shape, and a through-hole 21 is formed at a diameter through which the pin 12 of the bolt 10 can pass, and the through-hole 21 The general nut is applied to the side wall of the thread 23 is formed in a size corresponding to the thread 13 of the bolt 10, the through-hole through such a thread 23 of the nut 20 in the upper and lower directions A plurality of resin receiving grooves 24 are formed at equal intervals along the inner wall circumference of the 21.

The resin receiving groove 24 of the nut 20 may also be configured such that its position varies depending on each pitch, similarly to the resin receiving groove 14 of the bolt 10. It is formed at the same position for each pitch to pass in the vertical direction.

In addition, it is apparent that the resin receiving groove 14 of the bolt 10 and the resin receiving groove 20 of the nut 20 may be configured at the same number and at the same position, or may be configured at different numbers and at different positions. .

When the resin receiving groove 14 of the bolt 10 and the resin receiving groove 24 of the nut 20 are formed, the bolt 10 and the nut 20 are manufactured in a general shape, and then using equipment such as an end mill. Resin receiving grooves 14 and 24 may be formed in the thread 13 of the bolt 10 and the thread 23 of the nut 20, respectively. It is also possible to form threads laterally after equally spaced grooves, and the manufacturing method is not particularly limited.

In this state, the holes of both objects (not shown) are drilled, and the threads of the nut 20 are screwed to the threads 13 of the pins 12 while the pins 12 of the bolts 10 are passed through the holes. 23) by engaging and rotating both ends of the object to the bolt 10 and the nut 20 is fastened.
