120: flange 122: edge

130: thread portion 132: top thread

The present invention relates to a washer-shaped flange bolt, and more particularly, to a washer-shaped flange bolt that can maintain the binding force and assembly torque, even if the combined nut does not occur even when used in thin panels and components It is about.

In general, a vehicle is equipped with a large number of components, and when mounting the components, many bolts of various types are used and fixed.

Many of the bolted parts are flanged bolts, as shown in Figs. 1A and 1B, in order to be able to maintain their cohesion until the vehicle is dismantled and to apply an appropriate assembly torque to the bolt outer diameter. A separate spring washer 13 or conical washer 14 or the like which is brought into contact with the flange 12 of 10 is used.

However, when the thickness of the panel portion to which the parts are assembled is thin, and the thickness of the parts is thin, the spring washer 13 or the conical washer 14 cannot be used.

The reason for this is that the flange bolt 10, which is integrally formed by separately coupling the spring washer 13 or the conical washer 14, is usually about 3 to 4 millimeters (mm) because the thread 15 is formed only to the end of the washer. Is the part without the thread (15) exists.

Therefore, if the panel part to which the parts are assembled and the thickness of the parts do not exceed 4 millimeters (mm), when the nut 15 (not shown) that is assembled with the part that is not threaded is processed, the flange bolt 10 Badness will occur.

Thus, although the flange bolt 10 is used in thin panels and components, there is an urgent need for the development of a new bolt that can maintain the coupling force and the assembly torque.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a washer-shaped flange bolt that can maintain sufficient coupling force and assembly torque even when used in thin panels and components without using separate spring washers or conical washers. To provide.

In the washer-shaped flange bolt that can maintain the coupling force and the assembly torque even when the thin panel and components according to the present invention for achieving the above object, the shape of the head and the flange of the bolt is integrally coupled Characterized in that consisting of.

According to an embodiment of the present invention, the lower portion of the flange is inclined to a predetermined depth inward to be coupled with the threaded portion.

According to an embodiment of the invention, it is preferable that the edge and the top thread of the lower outer side of the flange are formed in a straight line with each other.

According to an embodiment of the present invention, it is preferable not to form a thread between the uppermost thread of the threaded portion and the threaded portion coupled to the inner side of the flange.

Hereinafter, a preferred embodiment of a washer-shaped flange bolt according to the present invention will be described with reference to the accompanying drawings.

Figure 2 is a perspective view showing a washer-shaped flange bolt according to the present invention, Figure 3 is a cross-sectional view showing a washer-shaped flange bolt according to the present invention.

As shown in the figure, the washer-shaped flange bolt 100 to maintain the coupling force and the assembly torque even when used in thin panels and components according to the present invention, easy fastening operation using a fastener (not shown) In order to do this, a head portion 110 having a polygonal shape, a flange 120 having an outer diameter larger than the outer diameter of the head portion 110, and a threaded portion 130 formed at the lower portion of the flange 120. It is composed of

Here, the flange bolt 100 according to the present invention is to be made in a shape in which the head 110 and the flange 120 is integrally coupled when forming.

The flange 120 of the bolt 100 is different from the generally formed flat flange so that its lower portion is inclined to a predetermined depth inwardly to be coupled with the threaded portion 130.

That is, when processing the flange 120 of the bolt 100, the planar portion of the flange is processed into the conical washer (see Fig. 1b) shape toward the inside, preferably into a depth of about 1 millimeter (mm) The part can act as a washer.

As described above, the flange 120 of the flange bolt 100 may be processed integrally with the head 110 to provide an effect of reducing the cost of the flange bolt 100.

In addition, since the flange bolt 100 and the washer do not need to be separately separated from each other, the flange bolt 100 and the washer do not need to be combined, thereby saving the time required for the joining operation.

In addition, the lower outer edge portion 122 and the top thread 132 of the flange 120 is formed to be in a straight line with each other.

The thread 132 is not formed between the upper thread 132 of the flange bolt 100 and the thread part 130 coupled to the inner side of the flange 120.

This is to make the same as the shape of the conical washer that is generally used, when the nut (not shown), or when the fastening member is fastened to contact the edge portion 122 of the lower outer side of the flange 120 Since the nut is not fastened to the inner side, there is no need to form a thread.

That is, when the flange bolt 100 is fastened to the fastening member, the edge portion 122 is in contact with and no longer tightened, so that the thread from the lower inner side of the flange 120 to the uppermost thread 132 is formed. This does not need to be processed, which results in saving the cost and time required for thread processing.

Brief description of the operation of the washer-shaped flange bolt according to the present invention and the effect thereof as follows.

First, the user inserts the flange bolt 100 to the perforation of the fastening member (not shown) to be fastened.

At this time, a separate washer does not need to be interposed between the flange bolt 100 and the fastening member.

After the flange bolt 100 is inserted into the perforation part, the lower outer edge portion 122 of the flange 120 contacts the upper end portion of the fastening member by using an appropriate fastener, and then clamps until no further rotation occurs. do.

Although the above has been illustrated and described with respect to the preferred embodiments of the present invention, the present invention is not limited to the above-described embodiments, but in the art to which the present invention pertains without departing from the spirit of the invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such changes will fall within the scope of the claims set forth.

According to the washer-shaped flange bolt according to the present invention as described above, the thin panel by solving the troublesome problem of using a separate washer as well as preventing the phenomenon of the nut is coupled to the portion that is not threaded processing And it can be used in parts to provide the effect of maintaining the bonding force and the assembly torque.
