  • the present invention relates to a nut with a seal washer having a water stop function used in combination with a bolt.
  • a through hole is formed in the body, a bolt is inserted, and the part is fixed with a nut.
  • a washer with a water-stopping sponge attached is interposed on the surface to prevent water from entering from the gap between the bolt and the through hole. Examples thereof are shown in Patent Document 1 and Patent Document 2.
  • an object of the present invention is to provide a nut with a seal washer that solves the above-mentioned conventional problems, has no water sag, has a stable water stop function, and has a good fastening workability.
  • the present invention made to solve the above-mentioned problems is a nut with a seal washer in which a seal washer is attached to the seat surface side of the nut body, and the lower surface of the outer peripheral portion of the seal washer is lower than the lower surface of the inner peripheral portion.

  • the seal washer is caulked and fixed to the seat surface side of the nut body as in claim 2, and the nut body can be a flanged nut as in claim 3. .
  • the nut with a seal washer according to the present invention is used in combination with a fastener such as a bolt, and when an axial fastening force is applied to the seal washer by a bolt inserted through the center hole, The elastic seal material at the outer peripheral portion provided on the lower surface is compressed and adheres to the surface of the counterpart material. When an axial fastening force is further applied to the seal washer from this state, the lower surface of the inner peripheral portion of the seal washer is in a state of metal touch with the counterpart member.
  • the nut with a seal washer according to the present invention is in a state where the inner periphery of the seal washer is in metal contact with the mating member when the fastening is completed. . Moreover, unlike conventional ones, no further compressive load acts on the elastic seal material at the outer peripheral portion, so that the elastic seal material at the outer peripheral portion is not deformed so as to be crushed, and the water stop function is impaired. It will never happen.

As will be described later, the lower surface 8 of the inner peripheral portion becomes a metal touch surface with the mating member at the time of fastening.
  • the material of the elastic sealing material 10 is, for example, an olefin-based elastomer, but is not limited thereto, and a general sealing material such as rubber can be used. Further, the means for attaching the elastic sealing material 10 to the lower surface 7 of the outer peripheral portion of the seal washer 2 is arbitrary, and may be integrally formed by an insert molding method, or may be attached with an adhesive.
  • FIG. 3 shows a state in which the nut with seal washer of the first embodiment is combined with the bolt 20 and the two mating members A and B are fastened.
  • the elastic sealing material 10 projecting downward from the seal washer 2 first contacts the surface of the mating member A.
  • the elastic sealing material 10 is gradually compressed.
  • the lower surface 8 of the inner peripheral portion of the seal washer 2 is in a metal touch with the mating member A. If an axial force is applied to the bolt 20 in this fastened state, no loosening occurs. Further, since the elastic sealing material 10 is not further compressed, the elastic sealing material 10 is not deformed so as to be crushed. As a result, a stable water stop function can be maintained semipermanently.
  • the area of the lower surface 8 of the inner peripheral portion of the seal washer 2 is determined according to the required fastening axial force and the strength of the mating member. Further, the step between the lower surface 7 of the outer peripheral portion and the lower surface 8 of the inner peripheral portion is determined according to the required compressibility of the elastic sealing material 10.

  • 10 can be more reliably compressed. Since other points are the same as those of the first embodiment, description thereof is omitted.
  • the nut body 1 is a square nut, and has a structure that can be fixed to another member by using a recess 12 formed on a side surface thereof. Since other points are the same as those of the first embodiment, description thereof is omitted.
  • the bottom surface 8 of the inner peripheral portion of the seal washer 2 makes a metal touch with the mating member when the fastening is completed. . Moreover, since no further compressive load acts on the elastic sealing material 10 provided on the outer peripheral portion, the elastic sealing material 10 will not be deformed so as to be crushed, and the water stop function may be impaired. There are no advantages. Furthermore, since the nut body 1 and the seal washer 2 are integrated, the fastening workability can be improved.

Abstract

L'invention concerne un écrou muni d'une rondelle d'étanchéité, avec lequel le dévissage ne se produit pas, qui présente des caractéristiques stables en matière d'étanchéité à l'eau et d'excellentes propriétés de serrage. Cet écrou ayant une rondelle d'étanchéité comporte une rondelle d'étanchéité (2) fixée au côté de la surface d'appui d'un corps d'écrou (1). La rondelle d'étanchéité (2) présente une forme étagée dans laquelle la surface inférieure (7) d'une section périphérique externe est supérieure à la surface inférieure (8) d'une section périphérique interne. La surface inférieure (8) de la section périphérique intérieure sert de surface de contact métallique avec un autre élément lors du serrage, et un matériau d'étanchéité élastique (10), qui fait saillie vers le bas de manière plus prononcée que la surface inférieure (8) de la section périphérique interne, est installé sur la surface inférieure (7) de la section périphérique externe.
