Definitions

  • the invention relates to a polygon socket wrench insert with an internal polygonal holder, in the wall of which there is at least one elastic element such as an O-ring, through the objects with an external polygon in the Polygonal socket can be fixed.
  • Nuts, cap screws, glow plugs, spark plugs or The like have outer polygon and can not only with the corresponding open-end wrenches, but also with polygonal socket wrenches to be assembled.
  • Polygonal socket wrenches are known in different embodiments. They exist generally from a tubular key insert that so-called nut, with an internal polygon for the recording the key surfaces of nuts, cap screws, glow plugs, Spark plugs or the like.
  • the drive can be manual or with a motor respectively.
  • Socket wrench inserts can also be used when assembling Objects at long distances or on for the fitter out of the way to be used, it being however, problems can arise because the objects are made of loosen the socket wrench insert without the fitter removing it can take. Will under the conditions mentioned for example, a mother loosened up, she cannot go together be moved with the key insert, since after loosening falls out of the key insert. For example a nut must be screwed on, it must be replaced by another Expensive means brought to the associated screw and there are held, so that the socket wrench can be attached and rotated.
  • the object of the invention is therefore a Socket wrench insert to provide the outer polygon objects such as nuts, cap screws, glow plugs, Spark plugs or the like fixed so that it is without additional effort not from the key insert dissolves.
  • this object is achieved in that the wall of the polygonal socket of a polygon socket wrench insert at least one elastic element the outer polygon of nuts, Cap screws, glow plugs, spark plugs or the like in the Fixed polygon mount.
  • the elastic element is preferably an inner circumferential O-ring.
  • the O-ring is there preferably made of an elastically deformable material.
  • a large number of substances are suitable for this, the A person skilled in the art preferably chemically and mechanically resistant Select materials. Elastomers are particularly preferred, especially Perbunan.
  • the material in unstressed condition a defined shape that it too after strong deformation in the elastic range up to if necessary, to the lowest possible Deformation (residual shape change) remains. It turned out to be proven expedient that the O-ring in the area of Polygonal socket is introduced, which for opening the Socket insert points.
  • the ring is positioned so that part of it Diameter in the wall of the key insert, while a part in the interior of the polygonal interior protrudes.
  • a circumferential groove is made in the wall introduced that receives the O-ring.
  • the key insert can now be used as with conventional ones Socket wrenches over the outer polygon of an object be plugged in, with pressure due to the elastic O-ring the key surfaces of the polygon is exercised, so that the object is fixed.
  • circumferential O-ring instead of the circumferential O-ring, other elastic ones can be used.
  • Elements are used.
  • Amount and Arrangement of the balls are variable and are the Adjusted the purpose of the key insert. You can at a distance from each other on at least one circumferential line attached or distributed arbitrarily.
  • the cutouts for Recording the balls are preferably in the angles that formed by the side walls of the polygonal interior become.
  • the fixation results in both loosening and compared to considerable advantages when tightening objects Key inserts without fixation.
  • the key insert is mounted on the screw Screw inserted and the insert with a suitable Drive device connected. This device can do so be designed so that the key insert on large Distances or positioned in hard to reach places can be.
  • the key insert can now be used together with the Screw to be moved to the place where the screw to be installed without the screw on the way dissolves there. After the screw has been tightened, the Key use through power transmission via the Drive device can be loosened from the screw.
  • FIG. 1 a particularly preferred embodiment of the polygonal socket wrench insert according to the invention for receiving nuts or cap screws is shown.
  • the particularly preferred embodiment of the polygon socket wrench insert according to the invention in FIG. 1 has on one side a receptacle 20 for connection to a drive device, while on the other side there is an inner polygonal receptacle 30 for the wrench surfaces of a screw 40 shown as an example.
  • the key insert is preferably tubular, but it can also be designed in other forms.
  • the cavity 70 shown between the receptacle 20 and the polygonal receptacle 30 can also be configured in different shapes and sizes.
  • the key insert according to the invention is preferably used for receiving nuts and head screws, it can be designed in such a way that it is also suitable for receiving spark plugs or the like. For the assembly of spark plugs, it is designed, for example, in such a way that the cavity 70 can receive the part of the spark plug above the outer polygon.
  • An inner circumferential O-ring is in the inner polygonal holder 30 50 introduced.
  • the O-ring preferably consists of an elastic material like rubber and its dimensions are chosen so that the weakening of the Key insert wall is minimized.
  • the ring will be like this positioned that part of its diameter in the Wall 60 of the key insert is located while part protrudes into the interior of the polygonal socket 30. Is to a circumferential groove in the wall of the polygonal socket provided that receives the O-ring.
  • the key insert can be used like conventional ones Socket wrenches over the polygon of an object like that Screw 40 are inserted, the elastic O-ring Exerts pressure on the key surfaces of the polygon, so that the object is fixed.
  • the o-ring is like that designed that the screw is not without additional Exertion of force from the internal polygon mount releases. Size and The position of the O-ring is determined by the intended use of the Key insert adjusted so that the weakening of the Key insert wall is as low as possible. Should one Nut must be fixed, the O-ring must be a smaller one Force can be applied as, for example, for fixation a spark plug is necessary, and the O-ring can be designed accordingly smaller. It can too several grooves with O-rings can be provided if the wall the inner polygonal mount is not weakened too much becomes.
  • circumferential O-ring 50 instead of the circumferential O-ring 50, other elastic ones Elements are used.
  • several elastic rubber balls are introduced. Amount and Arrangement of the balls are variable and are the Adjusted the purpose of the key insert. You can at a distance from each other on at least one circumferential line attached or distributed arbitrarily.
  • the cutouts for Recording the balls are preferably in the angles that formed by the side walls of the polygonal interior become.
