The present invention relates to a material fastening device used to fix two or more materials, and more particularly, to an improved material fastening device to fix a material very easily and quickly in a narrow space.

In general, to fix two or more materials, fastening by bolts and nuts is common.

Fastening by bolts and nuts is a method of inserting bolts at the front of the material and fastening the nuts at the back of the material. Therefore, it is absolutely necessary to secure a large space for inserting bolts or fastening nuts at the front and back of the material. It should be tightened several times.

Therefore, when the space for fastening bolts and nuts is narrow, it is very difficult or impossible to fix the material.

In addition, when tightening the nut several times in a narrow space is very inconvenient and takes a long time to tighten because the space is small, causing a problem that productivity is reduced due to a long tightening work time when fastening a large number of materials do.

It is an object of the present invention to provide a material fastening device that can easily and quickly fix a plurality of materials even in a narrow space.

The present invention for achieving the above object, as a material fastening device for fixing a plurality of materials; Gildan long hole is formed in the material; Planar portions are formed on both sides to penetrate the long hole, and the gap between the plane portions is narrower than the width interval of the long hole, and the engaging portion is formed on a portion perpendicular to the flat portion, and the back side has numerous jagged protrusions to prevent loosening. A fastening member having a head portion having an ingling portion, an elongated shaft portion penetrating a long hole on the rear surface of the head portion, and a locking pin which is fixed to the middle portion of the shaft portion and protrudes to one side; A central hole into which the shaft portion is fitted, a fitting groove portion into which a locking pin is inserted in a longitudinal direction on one side of the central hole, an inclined groove portion extending from the rear side of the fitting groove portion to be pierced in a circumferential direction, and inclined in the direction of the tip portion, and the tip portion; It is characterized in that it comprises a rotational fastening member having a myriad in the form of a number of teeth projection for preventing loosening.

Referring to the material fastening apparatus of the present invention in more detail based on the accompanying preferred embodiments as follows.

1 is an overall perspective view of a material fastening apparatus of the present invention, Figure 2 is a perspective view shown to be separated.

1 and 2, the plurality of raw materials 1, 2 are separate raw materials 1, 2, respectively.

The present invention is a material fastening device for overlapping and fixing a plurality of the material (1,2) is a long hole (3) is drilled in the material (1,2).

In addition, the fitting fastening member 10 and the rotation fastening member 20 is provided.

The fastening member 10 is comprised to have the head part 11 and the shaft part 15 integrally formed in the back surface.

The head portion 11 allows the flat portions 12 and 12 'to be formed at both sides to penetrate the long holes 3 of the raw materials 1 and 2, but the spacing 12a of the flat portions 12 and 12' It is comprised so that it may have narrower space | interval than the width space | interval 3a of the long hole 3.

In addition, the portion perpendicular to the planar portions 12 and 12 'is configured to have engaging portions 13 and 13' formed wider than the width interval 3a of the long hole 3.

On the back of the head 11 is to have a myriad 14 of serrated protrusions for preventing loosening, there is an elongated shaft 15 penetrating the long hole 3 on the back of the head 11.

In addition, the locking pin 16 is fixed to the middle of the shaft portion 15 so as to protrude.

The pivot fastening member 20 has a central hole 21 into which the shaft portion 15 is fitted, and one side of the central hole 21 is fitted with a fitting groove 22 into which the locking pin 16 is inserted in the longitudinal direction. The inclined groove portion 23 extending from the rear side of the groove portion 22 is pierced in the circumferential direction, but is configured to have an inclined groove portion 23 that is inclined in the tip direction.

In addition, the front end of the rotational fastening member 20 is configured to have a myriad 24 in the form of a number of jagged protrusions for preventing loosening.

The present invention is to be fixed in a state where a plurality of raw materials (1, 2) are stacked as shown in Figure 1, the shaft portion 15 of the fitting fastening member 10 to the central hole 21 of the rotation fastening member 20 It is to be fastened in the fitted state but the locking pin 16 is fastened in the fitted state in the fitting groove (22).

Next, as shown in the solid line in Figure 3, the head 11 of the fastening member 10 is to be inserted into the long hole (3) at the rear side of the material (1, 2) to be fitted toward the flat portion (12, 12 ') When the head 11 is penetrated through the long hole 3 and rotated by 90 ° as shown by the arrow, the locking parts 13 and 13 'are caught by the material 1 as shown by the pseudo-line. 3) through the head 11 will not come out.

This state is a state in which the locking pin 16 is fitted into the fitting groove 23 as shown in FIG. 4. In this state, when the rotation fastening member 20 is rotated as shown by the arrow, the locking pin 16 as shown in FIGS. 5 and 6 ( 16 is rotated to reach the end of the inclined groove (23).

At this time, since the inclined groove 24 is formed to be inclined in the direction of the tip end, the rotation fastening member 20 is in a state of being moved in the direction of the tip end, that is, in the direction of the material 1 and 2, thereby strongly compressing the materials 1 and 2. In this case, the materials 1 and 2 are in a state of being fixed to each other by the head 11 and the rotational fastening member 20.

In the state in which the fixing of the raw materials 1 and 2 is completed, the knurling parts 14 and 24 are brought into close contact with the surfaces of the raw materials 1 and 2, and thus act as a spring washer, thus loosening the rotation fastening member 20. This will be prevented.

Since the material fastening device is mainly used as a means for fixing the materials 1 and 2 having a thickness of 2 to 3 mm, it can be very useful for fixing the materials 1 and 2 in the field of elevator manufacture.

And if there is no space for fastening at any one of the front or rear of the material (1, 2) and the other side is fastening is possible when the space for fastening is narrow.

In addition, since the fastening member 20 can be fastened by only half the rotation, fast fastening can be achieved.

According to the above description, the present invention not only provides a material fastening device which can fix the material very easily and quickly in a narrow space, but also when used as a fastening device for mass production, it is possible to fast fasten the productivity greatly. It is a useful invention that provides the effect to be made.
