The present invention relates to a tightening nut that can be attached to an arbitrary position of a bolt. 2. Description of the Related Art Conventionally, various techniques of a nut which can be attached to an arbitrary position of a long bolt have been disclosed, but almost all of them have been disclosed after attaching a plurality of divided nuts to the bolt. Thus, it is rotated and fixed so as to have the original nut shape, and is formed by combining a plurality of members. [0003] In the above conventional method,
Although there is no problem in function and strength, there is a problem that the cost is increased due to a plurality of members constituting the nut, which is very uneconomical. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to reduce the cost by simplifying the structure of the nut, to simplify the mounting, and to reduce the strength. It is intended to provide a tightening nut which can be reliably obtained. [0005] As a means, on one side of a plurality of nut body consisting of an outer surface formed a substantially internal thread portion in the middle to form an opening cut open so slightly larger than the outer diameter of the mounting bolts, the opening At least on both sides of the part
On one side, a fastening tool is applied to the side with the opening.
Opening stopper protruding outward from the outer surface so that it does not come out
And a notch is formed in the female screw portion facing the opening, and the female screw is screwed to the bolt by tightening the opening in the closing direction. . [0006] According to the above structure, since the member constituting the nut is only the nut main body, the cost can be suppressed by simplifying the structure. An opening is formed in one side surface of the nut body, and a cut portion is formed in the female thread portion facing the opening, and the female thread portion is screwed into the bolt by tightening the opening portion of the nut body in the closing direction. In addition, the bolt can be attached to an arbitrary position, and the deformation of the female screw portion can be suppressed when the opening is tightened by the cut portion. Further, since the opening-stopping pieces of the opening are formed on at least one side of both sides forming the opening of the nut main body, a tool such as a spanner used when tightening the nut to the bolt does not catch on the side surface where the opening is formed. You can do so. That is, after the nut is attached to the bolt, when the nut is tightened with a tool, when the tool is tightened by applying the tool from the direction shown in FIG. The object of the present invention is to solve the above-mentioned conventional problem, for example, since it is possible to re-open, it is possible to regulate the direction in which the tool is applied so that the tool does not hang on the side surface. Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a plan view showing an embodiment of the present invention, and FIG. 3 is a perspective view showing a state where an opening is tightened. Reference numeral 1 denotes a nut body, and reference numeral 2 denotes an opening formed so as to be slightly larger than an outer diameter of a bolt to be attached. Reference numeral 3 denotes a notch formed in the female screw portion 4, which is formed at a position substantially opposed to the opening 2. The outer shape of the nut body may be formed so as to be substantially hexagonal when the opening 2 is tightened in the closing direction as shown in FIG. 3, or may be formed in a square shape (not shown). There is no limitation. Reference numeral 5 denotes an opening stopper formed on one of both sides 6, 6 of the opening 2, and projects outward from the outer side of the side surface so that a fastening tool is not applied. As another method for preventing the fastening tool from hanging on the side surface having the opening, as shown in FIG. 4, the outside surface of both sides 16, 16 of the opening 12 is removed. A method of forming a shape, a method of coloring both sides of the opening with a paint or the like to give a warning (not shown), and the like can be easily inferred. FIG. 5 is a diagram showing a use state of the embodiment of the present invention. With the opening 2 of the nut body 1 fitted in the desired position of the bolt A, using a tool such as pliers, it is securely tightened and fixed in the direction in which the opening 2 is closed, and then tightened with a spanner or the like. It can be tightened by rotating the nut body 1 with a tool. As described above in detail, according to the tightening nut of the present invention, since the nut constituting only the nut body, the cost can be suppressed by simplifying the structure. It is very economically advantageous. An opening is formed on one side of the nut body, a cut is formed in the female thread facing the opening, and the female thread is screwed into the bolt by tightening the opening of the nut body in the closing direction. , Can be attached to an arbitrary position of the bolt, and the deformation of the female thread portion can be suppressed when the opening is tightened by the cut portion. That is, the labor and time required to move the nut while turning it from the end of the bolt to the desired position can be saved, and the nut is not deformed at the time of work, so that reliability and reliability are improved. Further, by forming the opening-stopping pieces on at least one side of both sides forming the opening of the nut main body, a practically useful tightening nut such as further improving the reliability of operation can be obtained.
