Definitions

  • the invention relates to a sealing arrangement, comprising a plug and a seal, for installation in a bore, wherein the plug is constructed substantially cylindrical, with a lower recess provided at the foot, and wherein the seal is constructed substantially tubular cylindrical, with a protruding, in assembly position, the bore cross-head and a protruding inner tooth.
  • a sealing arrangement comprising a plug and a seal, for installation in a bore, wherein the plug is constructed substantially cylindrical, with a lower recess provided at the foot, and wherein the seal is constructed substantially tubular cylindrical, with a protruding, in assembly position, the bore cross-head and a protruding inner tooth.
  • a tubular-cylindrical seal In a bore, an outlet opening of a pipe, a tubular-cylindrical seal is first inserted and then introduced a cylindrical plug.
  • the seal has at the bottom a bead-like edge with an inner tooth.
  • the inner tooth engages in the recess on the plug and the bead-like edge is spread by the plug. In this way, the resistance for removing the plug from the seal is increased and the plug is secured against falling out.
  • the holder of the seal Over a radially extending along the bead-like edge spring, the holder of the seal is reinforced on the plug.
  • the invention is based on the object to reduce the force in the installation of the seal assembly in a bore and to increase the resistance when removing the plug from the bore and to improve the mounting safety and the sealing property of the seal assembly on.
  • This object is achieved according to the invention in that the stopper has an upper recess arranged between the foot end and a head end of the stopper, in a partial assembly position the inner tooth of the seal bears against the lower recess of the stopper in a final assembly position of the inner tooth of the seal rests against the upper recess of the plug, and that the seal at least one upper, protruding sealing ring on the outside, at least one lower, protruding securing means on the outside, at least one upper, protruding sealing ring on the inside, and at least one radial section at the bottom the seal, which extends axially at least to the inner tooth has.
  • the invention teaches a seal assembly comprising a plug and a seal for installation in a bore, wherein the plug is constructed substantially cylindrical, with a first recess and a second recess, and wherein the seal is constructed substantially tubular cylindrical, with a projecting head portion, at least one upper, outer annular sealing ring, at least one outer lower securing means on the outer side, at least one upper projecting inner sealing ring, a protruding inner tooth / inner step, with at least one radial cut at the bottom of the gasket extending axially at least to the inner tooth / inner step.
  • the gasket 1 is substantially cylindrical. It is preferably made of an elastic material, such as rubber. At the top is a head portion 2 to prevent the gasket from slipping into the bore as the plug is pressed into the bore.
  • the head part preferably has a larger diameter than the bore.
  • Sealing rings 3 are arranged on the upper outer diameter side to ensure the sealing effect to the bore.
  • Sealing rings 4 are arranged on the inner diameter side to ensure the sealing effect for plugging.
  • Locking means 5 are disposed on the lower outside diameter side to ensure resistance when the plug is released from the bore.
  • An inner tooth 6 or inner step allows the seal to lock in a desired position over the plug while the seal is being mounted on the plug and while being pressed into the bore while plug and seal.
  • the shape of the tooth or step allows the seal to slip over the plug, lock in place, and increase the outer diameter of the seal in the lower region (foot area). Furthermore, the shape of the seal prevents the seal from sliding over the plug, and the shape of the seal provides sufficient resistance when a force is applied to the plug to release it from the bore.
  • a radial cut 7, machined or formed on the underside of the seal, allows the seal to open as it slides over the plug, thereby reducing the force to be applied when installing the seal on the plug.
  • the cut also allows the bottom (foot) of the gasket to open when the plug and gasket are pressed into the bore, and the cut also permits that the seal increases the outside diameter in a manner that properly counteracts the applied force for extracting the plug from the bore.
  • FIGS. 2A, 2B, 2C, 2D Function description fv ⁇ l.
  • FIG. 2A all components, plugs 21, seal 22, bore 23, are shown prior to assembly.
  • the plug has a head end 24, an upper recess 25 and a lower recess 26 at the foot end 27.
  • FIG. 2B shows how the seal 22 is installed on the plug 21.
  • the inner tooth 6 snaps into the first recess or into the lower recess 26 on the plug 21.
  • a seal assembly comprising a cylindrical plug 21 and a tubular cylindrical seal 22 is installed in a bore 23 in two assembly steps.
  • an inner tooth 6 of the seal 22 engages in a lower recess 26 of the plug 21; in the Final assembly position engages the inner tooth 6 of the seal 22 in an upper recess 25 of the plug 21 a.
  • the resistance for removing the plug 21 from the bore 23 is increased.
  • the force required to install the sealing arrangement in a bore 23 is reduced and the assembly safety and the sealing property of the sealing arrangement are improved.
  • the securing effect ie the property that does not allow the stopper to be easily pulled out
  • the securing means such as circlips, securing levels, locking teeth and / or locking knobs, is caused at the bottom of the seal on the outer diameter, said securing means of the inner surface (the lower edge) of the bore while the lower part of the seal opens due to a radial cut and through the inner tooth / inner step (on the inner surface) acting on the upper recess of the plug.
  • the present invention includes both the above-described gasket in isolation, as well as the above-described seal assembly comprising a plug and a seal.

Abstract

L'invention concerne un système d'étanchéité qui comprend un bouchon (21) cylindrique et un joint (22) en forme de cylindre tubulaire, et est installé en deux étapes de montage dans un orifice (23). En position de montage partiel, une dent interne (6) du joint (22) s'accroche à un creux (26) inférieur du bouchon (21). En position de montage final, la dent interne (6) du joint (22) s'encliquette dans un creux (25) supérieur du bouchon (21). La dent interne (6) de la face interne du joint (22) et un moyen de sécurité de la face externe du joint (22) permettent d'augmenter la résistance pour empêcher que le bouchon (21) ne sorte de l'orifice (23). Grâce au système d'étanchéité selon l'invention, la force nécessaire lors de l'installation du système d'étanchéité dans un orifice (23) est réduite tandis que la sécurité du montage et la propriété d'étanchéité du système d'étanchéité sont améliorées.
