In order to prevent loosening, the present invention is a bolt and nut, the nut 10 has a taper 12 which is narrowed toward the outside toward one side is formed protruding, the taper 12 has a plurality of incision grooves 14 and the inner thread 16 is characterized in that the extension is formed. Alternatively, the bolt 20 is characterized in that the taper 23 extending from the screw rod 24 to the bolt head 22 is formed.

Description

Fixing nut or bolt {NUT OR BOLT}

The present invention relates to bolts and nuts, and more particularly, when fastening a structure such as steel structures, panels, concrete, etc. (hereinafter referred to as "structures") as bolts and nuts, it is possible to firmly fasten and fix it at the correct position. It relates to a fixing nut or bolt that can prevent loosening.

In general, bolts and nuts which are mainly used in assembling and connecting the structure are fastened to each other through a bolt hole formed in the structure to fix the structure and the structure.

When the weight of such a structure is heavy or excessively large, it may be difficult to fasten the bolt and nut as the bolt holes are shifted from each other when one side is drooped during assembly, and this phenomenon may be referred to FIG. 5 or 5A. Will be more readily understood.

As such, when the structures P1 and P2 and the bolt holes H1 and H2 are displaced from each other, the worker inserts the bolt 1 into the hole H1 from one side and forcibly inserts the bolt 1 into the other hole H2 or beats it with a hammer or the like. Forced insertion, at this time, the screw is scratched or damaged, resulting in a reduction in the strength of the bolt, thereby causing a risk, such as broken. And, there was a problem that the nut is not assembled or the working time is delayed.

In addition, there is a disadvantage in that the assembled structures are separated from each other in position to increase the defect rate as the accuracy is lowered.

Alternatively, to prevent the nut from loosening due to vibration of the structure or external impact force, a washer or spring washer, a double nut, or a fixing pin may be used, which also requires a separate anti-loosening member as described above. There is a hassle to reduce work efficiency, such as the addition of parts processing and work processes.

Due to this, the present invention to solve the same problem as the prior art, when assembling the structure as well as the structure to guide the bolt holes to be placed in place, and fastening between the structures can be fastened precisely and firmly or Suggest a bolt.

Alternatively, the present invention provides a fixing nut or bolt that prevents the nut fastened to the bolt from being easily loosened by vibration or impact force of the structure.

The present invention is a bolt and nut, the nut 10 is formed on the one side tapered (12) narrowed toward the outside protruding, the taper 12 has a plurality of incision grooves 14, the inner circumference of the female screw ( 16) is characterized in that the extension is formed.

Alternatively, the bolt 20 of the present invention is characterized in that the taper 23 is extended from the screw rod 24 to the bolt head 22 is formed.

Fixing nut or bolt of the present invention having the features as described above to guide the structure and the structure to be placed in place with each other while the taper protruding in the nut is inserted into the bolt hole and the effect of improving the precision, fastening of the bolt and nut Since the work can be easily performed, there is an advantage of significantly shortening the working time.

In addition, the present invention has the advantage that the female taper is tightly fixed to the male screw tightly and firmly fixed by being tapered as the taper of the nut is inserted into the bolt hole, and prevented from loosening arbitrarily by vibration or impact force.

In describing the fixing nut or bolt of the present invention, it will be described in detail with reference to the accompanying drawings as follows.

First, Figure 1 is a perspective view showing the outer shape of the fixing nut according to a preferred embodiment of the present invention, Figure 2 is a longitudinal cross-sectional view of the nut according to the present invention.

The nut 10 of the present invention has a taper 12 which is narrowed toward the outside toward one side and protrudes, and the taper 12 has a plurality of cutout grooves 14 formed in the longitudinal direction. And the internal thread 16 is extended in the inner periphery. In addition, the outer circumference has a general shape that can form a multi-faceted surface and can be firmly rotated as a tool such as a spanner, and both ends of the female screw 16 is chamfered (C) to facilitate fastening with the bolt.

3 is a cross-sectional view illustrating a state in which the nut 10 and the bolt according to the present invention are fastened to the structures P1 and P2. When the nut 20 is engaged with the bolt 1, the end portion of the taper 23 is naturally inserted into the bolt hole H2, and then the nut 20 is tightened to be separated from the center of the bolt hole. It is seated in the correct position and tightened precisely. At this time, the taper 12 is gradually closed through the incision groove 14 while being in close contact with the corner portion of the bolt hole is pressed tightly with the male screw to be firmly fixed to prevent it from being arbitrarily released by vibration or impact force of the structure.

In addition, the cutting groove 14 may be engaged with the end edge of the bolt hole H2 so that the cutting groove 14 may be in close contact with each other, thereby preventing the phenomenon of loosening at random.

Figure 4 is a perspective view showing the appearance of the bolt according to another embodiment of the present invention. Referring to FIG. 4, the bolt 20 of the present invention has a taper 23 extending from the screw rod 24 to the bolt head 22. In other words, the edge portion where the bolt head 22 and the screw rod 24 are connected is gradually expanded to be positioned in the center while being in close contact with the bolt hole H1 according to the guide of the tape.

In addition, although not shown, it is also possible to form a groove recessed in the longitudinal direction in the taper 23 so that the groove is firmly fixed while engaging the end of the bolt hole H1, and the bolt 20 is also arbitrarily loosened. The phenomenon can be prevented.

1 is a perspective view showing the appearance of the fixing nut according to a preferred embodiment of the present invention.

2 is a longitudinal sectional view of a nut according to the present invention;

3 is a cross-sectional view illustrating a state in which the nut 10 and the bolt according to the present invention are fastened to the structures P1 and P2.

Figure 4 is a perspective view showing the appearance of the bolt according to another embodiment of the present invention.

Figure 5 is a plan view illustrating a fastening form of the bolt and nut according to the prior art.

FIG. 5A is a longitudinal cross-sectional view taken along the line "A"-"A" of FIG. 5; FIG.
