Definitions
- the present invention relates to an intermediate mounting type or a nut which is inserted from a tip of a port and reaches a mounting surface without requiring screwing.
- FIG. 1 AD 3414 A quick-tightening nut (Fig. 1) that can be inserted from the tip of the port at an angle and arrives at the mounting surface without the need for screwing was invented (Fig. 1 AD 344) (Patent No. 1337051)). After reaching the mounting surface, the nut is screwed into the bolt while being tilted so that it is parallel to the member from a state of being slanted.However, this nut is laterally attached to the mounting member or bolt during screwing or after tightening. When the force in the direction acts, it may rarely come off. In addition, this nut has the shape of the inside of the thread of a high nut, which is obtained by adding three general nuts, and is expensive to implement, making practical use difficult.
- the one-part intermediate insertion nut (Fig. 3 and Fig. 4), which can be inserted and mounted from other than the end of the port, has the same compressive deformation as ordinary nuts, as can be seen from the appearance. It is designed to have the same number of threads as ordinary nuts and to have the same performance as ordinary nuts by having half the thread of ordinary nuts as a pair of upper and lower threads.
- the quick-tightening nut and the one-piece intermediate insertion nut described above are inserted from a posture that is perpendicular or oblique to the bolt axis so that they are parallel to the member when fixed and do not come off.
- the member fixing surface is horizontal with the member, only a vertical force acts on the port when tightening. For this reason, it can be easily removed if it is affected by uneven friction of the member fixing surface during tightening or unstable posture. Even if the mounting member is displaced sideways after fixing, it may come off.
- the present invention provides a fast-tightening nut and a one-piece intermediate insertion nut having a structure for securely maintaining the state even during screwing or after tightening. Disclosure of the invention
- An aperture (3) or a substantially U-shaped notch (4) with a groove (2) or projection that can be screwed into the port is provided at the edge (1) that contacts the port in the fixed state.
- the port By tilting the surface (5) in contact with the above-mentioned material to be fixed (9) or providing a step (10) or providing a projection (11), etc.
- the port When viewed from the material to be fixed (13), which has a horizontal positional relationship, the port can be screwed to the port at the surface (5) in contact with the material to be fixed if the position is relative to the port.

- the port (7) is screwed into the port (7) at a position 180 degrees far away from the groove that can be screwed into the port (2), the bolt is set in place. Seen from (16), it is deviated (17), creating an inclination. In the middle of screwing, if the position is set around the port due to inclination, etc., the groove (2) that can be screwed into the port or the side opposite to the side where the projection is provided comes into contact with the fixed material (1 3) first . At this time, a force is applied to try to make the nuts parallel (18), and a force is applied to the bolts where it is screwed (19).

- a nut consisting of a part with an edge (8) that abuts (6) or screws (7) on a bolt is a conventional fast-tightening nut (Figs. 1 and 5) and a one-piece intermediate insertion nut ( 3 and 4) as well as the shape shown in Fig. 17. It has a section (28) with an edge (8) that abuts (6) partially on the bolt. Shapes as shown in Fig. 18 or Fig.

- Surface in contact with the material to be fixed By tilting (5) to (9) or providing a step (10) or providing a projection (11) etc., in the temporarily fixed state (12), the horizontal positional relationship with the vertical port is established.
- the port (6) When viewed from the material to be fixed (13), the port (6) is positioned relative to the port, and a groove (2) or projection that can be screwed into the port at the surface (5) that contacts the material to be fixed is provided.

- Fig. 23 shows an example in which the thread can be omitted in the groove (2) that can be screwed.
- the female screw of a general nut is loose with respect to the port so that the screw can be screwed smoothly, but the groove (2) that can be screwed into the port in the present case should have a shape that fits more closely to the port . Or it could be more loose and could be used for 3 minutes with M 10 for example.
- the surface (5) in contact with the material to be fixed may be the same hexagon as a general nut.
- the same spanner as a general nut can be used.
- the side length is desirably less than 17 mm.
- the nut may be made of iron or stainless steel regardless of its material.
- the surface of the conventional fast-tightening nut and the one-piece intermediate insertion nut that comes into contact with the material to be fixed should be inclined.
- the manufacturing method is to use a wire rod and formally, in addition to the press. It is also conceivable to use iron, aluminum, and plastic to make the mold.
- the groove (2) that can be screwed into the porto it is also possible to use a press at the time of manufacturing with a press.
- a press at the time of manufacturing with a press.
- unevenness for reinforcement may be provided in the surface portion or the bent portion. The edges may be bent.
- the quick-tightening nut and the one-piece intermediate insertion nut can be press-formed with a thin material, so that they can be provided at low cost. Also, since it is possible to manufacture with thin steel plates, it is possible to perform additional work to prevent falling off at the time of pressing, thereby improving safety at low cost. Furthermore, due to the thin material, when tightened, the nut as a whole is twisted and deforms, storing torque, and as a result, the nut is loosened by only three degrees and the tightening torque is lost. Even if it was loosened by about 180 degrees, torque remained, and it also functioned as a nut to prevent loosening. Industrial applicability
- the intermediate insertion nut according to the present invention can be used in all cases where it is necessary to attach a nut to an intermediate portion of a bolt having no end into which the nut is screwed.
