  • Fig. 20 shows a bag nut with a structure in which one of the seating surfaces of the intermediate insertion nut is closed.

  • a saw-shaped groove (7) is provided so that the bolt does not come off during insertion and the screw thread of the bolt can move in parallel.
  • a large groove mountain is necessary to increase the strength, so inevitably bolt piles (10) and valleys
  • a saw-tooth shape following (1 1) is desirable. At that time, the boundary between the groove and the thread of the intermediate insertion nut is almost continuous (12). Even if the tightening operation is performed in this state, the screw at the end of the insertion direction in the intermediate insertion nut ⁇ and the screw thread of the bolt will be pushed out of each other by tightening and will be displaced from the helical axis of the intermediate insertion nut. . Therefore, when the above-mentioned method is used to form an intermediate insertion nut, a groove that can be screwed into the bolt is provided.
  • an intermediate insertion nut with an angle of inclination (1 3) in a saw-shaped groove is also conceivable so that the distance from the object to be fixed is closer during insertion than when screwing. In that case, in order for the intermediate insertion nut to come off, it must be further in close contact with the object to be fixed. In other words, the structure cannot be removed unless it moves up the slope. Also, in this intermediate insertion nut, if the diameter of the threaded part is made smaller than the bolt diameter, when tightening work, the bolt will be moved to the back when entering the back while changing the posture. Because the force to push in is applied, even if the diameter of the threaded part is smaller than the bolt diameter, it can reach the back while pushing the nut apart. Therefore, it also functions as a locking nut.
  • an intermediate insertion nut with a saw-shaped groove arranged in an arc (14) can be considered. Insertion starts at an angle such that the screwed portion is farther away from the object to be fixed than the insertion path, and becomes almost parallel to the object to be fixed at the time of screwing. This also functions as a locking nut under the conditions described above.
  • the insertion path is twisted about the bolt insertion direction (15), or that the insertion path is twisted around the saw groove and the bolt insertion direction (16 ) Can also be considered. It also functions as a locking nut under the conditions described above.
  • FIG. 9 shows a single peak when the nut is cut off so that the bolt can slide up and down. Since this nut has no orientation on the mounting surface, it does not matter which is the seating surface.
  • FIG. 9 A simplified version of FIG. 9 is shown in FIG. The front is a saw-shaped groove and the back is a saw-shaped groove with an insertion path.
  • FIG. 14 is a half cross-sectional view of the front of the insertion path. The left half shows a cross-sectional view of the bolt core.
  • a step (2 0) or an inclination or a height difference between the groove surface (1 8) of the insertion path and the groove surface (19) that can be screwed or screwed with the bolt becomes higher on the groove surface side of the insertion path.
  • An object with protrusions is also conceivable.
  • the thread (1) or the groove that can be screwed with the bolt as long as it can be screwed without drawing a helix, a short straight line assembly or a projection assembly can be used. ,.
  • the diameter of the threaded portion will be described a little more below.
  • a taper (2 4) is added, it is screwed together (Fig. 17), and when tightening is performed, the slide (2 5)
  • the threaded part diameter also becomes smaller, and the force to spread out acts as a locking nut (Fig. 1).
  • the seating surface of the intermediate insertion nut may be hexagonal or octagonal, but the quadrangle seems to be a reasonable shape. It is desirable to chamfer each side to reduce the distance from the bolt shaft.
  • an intermediate insertion type long nut can be obtained by adding the nut to the bolt shaft direction.

Abstract

L’invention porte sur un écrou de type insertion intermédiaire comprenant un écrou général dont la face latérale est découpée afin d’obtenir une forme en C grossière et dont la portion coupée sert de passage d’insertion pour un boulon. Une rainure cannelée est formée dans le passage d’insertion permettant aux filetages d’un boulon d’être déplacés latéralement dans le passage d’insertion. En outre, un gradin apparaît à la limite entre le passage d’insertion formé par la rainure cannelée et les filetages femelles de l’écrou afin d’empêcher le boulon de sortir de l’écrou.
