Definitions

  • the present invention relates to a manual shut-off gun with a Housing and a device for protection against unintentional release of the Spray tube from the housing to which a spray tube is rotatably attached.
  • a kinked spray tube is used on the one front free end the high pressure nozzle for the discharge of the high pressure medium is arranged.
  • These kinked spray pipes are very practical to use to reach places that are very difficult to access.
  • the spray tube will fit twisted, then the high pressure medium through the twisted spray tube and the assigned nozzle released. It is otherwise difficult to do this reach accessible places.
  • Such an embodiment shows e.g. B. DE 44 16 939 A1.
  • a disadvantage of these known embodiments is that the spray tube is completely free is rotatable. It can therefore happen that the spray tube is inadvertently twisted so that the escaping high pressure medium is no longer controlled on a certain place is given, or in the worst case, the spray tube even releases from the manual shut-off gun. This can damage it too dangerous injuries.
  • the object of the present invention is therefore to provide a manual shut-off gun initially mentioned type to the extent that they are more reliable and is also easier to use.
  • the essential results Advantage that the spray tube rotates into a certain position and then there can be locked.
  • the danger of an uncontrolled twisting of the Spray tube no longer exists during the delivery of the high pressure medium. This practically rules out damage and injuries.
  • the locking device can be operated manually. However, it is also possible to design this locking device so that when you deliver the High pressure medium is actuated automatically.
  • This second embodiment has the advantage that the spray tube is always locked during operation. As soon as no High pressure medium escapes, the spray tube can be rotated again. It exists there is also no danger that the user will forget to lock the locking device manually actuate.
  • the locking device is a spring biased and is therefore practically constantly active.
  • the spring force must be overcome, when the spray tube is released the Locking device automatically active again.
  • This locking device can either be directly on the spray tube or on a component connected to the spray tube in a rotationally fixed manner.
  • a Angle indexing provided be e.g. is formed in steps of 10 ° or 15 °.
  • one or more stops can be provided, the one Allow rotation only by a certain angular range. It will however preferred if a 360 ° rotation is possible.
  • one or more connections may be provided.
  • the locking device is in Formed two approaches.
  • the first approach is rotatable with the spray tube connected, the other is rotatably connected to the housing of the manual shut-off gun connectable, e.g. via a manually operated lever.
  • the locking device There are two options for the locking device. The first is the approaches separate from each other, the second is the rotatable connection between the second approach and the case to solve.
  • a suitable element can be provided keep the locking device closed at all times. It is advisable to do this To use compression spring on the spray tube or an associated Component works.
  • FIG. 1 schematically shows a cross section through a manual shutdown gun 1 according to FIG shown the invention.
  • the manual shut-off gun 1 has two essentially mirror-symmetrically designed and arranged accordingly Housing shells 5 on. Only one of these housing shells 5 is shown in the figure shown.
  • the two shells 5 define a closed housing, the one Front wall 6, a rear wall 7, a bottom wall 8 and an end wall 9 has.
  • the high-pressure medium is fed through a high-pressure hose 4, which through a receiving opening 3 of an anti-kink sleeve 2 in the manual shut-off gun entry.
  • the high-pressure hose 4 is on an attachment of a press-in nipple 10 with a press sleeve 11 held sealing.
  • the high-pressure medium is then spray gun through the manual shut-off gun 1 16 fed.
  • the corresponding connection 12 is in Figure 2 and in the modified embodiment shown in Figure 3.
  • a valve housing 13 is provided, which with an inner bore 14 is provided with a conical end 15.
  • the spray tube 16 is screwed into a nipple 17, which in turn is from a Fastening nut, consisting of an outer part 18 and an inner part 19 is attacked.
  • the nipple 17 here has an extension 26, to which a corresponding one Approach 29 of the inner part 19 can create.
  • a seal 27 preferably an O-ring, is provided for sealing in the bore 14 .
  • the fastening nut consisting of the components 18, 19, is preferably made of two separate materials.
  • the inner part 19 is preferably a metallic one Material, which then with a plastic material to form the outer part 18th is encapsulated.
  • the contact surface between the outer part 18 and the inner part 19 can be wavy, serrated or otherwise to increase adhesion be trained.
  • the inner part 19 is provided with an internal thread, which is an external thread corresponds to the valve housing 13. Accordingly, the inner part 19 with the help of the outer part 18 are screwed on.
  • the outer part 18 and the inner part 19 turned back a little so that the nipple 17 no longer over the approaches 26,29 is pressed against the valve housing 13.
  • the spray tube 16 is correspondingly then freely rotatable.
  • FIG. 10 Another embodiment is shown in the embodiment according to FIG. It is of course also possible, also in this embodiment Fixing the fastening nut 18, 19 via indexing holes 20 and a pin 21 to be provided. It is further shown that a bent spray tube 16 ' can be used.
  • the fastening nut 18, 19 is only screwed on so far that a certain freedom of movement in Direction of arrows 24, 25 for the nipple 17 between the stop 29 and the Valve housing 13 is made. Loosening the fastening nut 18, 19 for one Twisting the spray tube 16 is therefore not necessary.
  • the lugs 26, 29 are each with a Provide teeth. This interlocking increases the security against rotation during the Operating when the bore 14 is traversed by the high pressure medium.
  • a spring 30 can be provided, which the nipple 17 in the direction of the arrow 24 presses and correspondingly the teeth 28 of the stops 26,29 in engagement bring.
  • a suitable design of the toothing 28 is now a simple rotation of the spray tube 16 in the direction of arrows 31, 32 at the same time Displacement in the direction of arrow 25 causes. The toothing snaps around a tooth further. The process can be repeated until the desired angular position is reached.
  • the object of the present invention results in a great deal more reliable manual shut-off gun, which at the same time adapts well allows different boundary conditions and also the cleaning of otherwise only difficult to access places allowed.
