Description

Die Erfindung betrifft eine Schnellkupplung für die Hubanschlagschraube und den Luftkopf einer Farbspritzpistole.The Invention relates to a quick coupling for the Hubanschlagschraube and the air head of a paint spray gun.

Stand der TechnikState of the art

Bei Farbspritzpistolen heutiger Bauart, dient die Schraube (1) für den Farbnadel-Hubanschlag, gleichzeitig als hinteren Verschluss der Farbnadel.In paint spray guns of today's design, the screw ( 1 ) for the paint needle stroke stop, at the same time as the rear closure of the paint needle.

D. h. man muss die Schraube entfernen, um die Nadel (2) herausziehen zu können. Beim Wiedereinsetzen der Farbnadel muss die Schraube (1) gegen die Federkraft der Farbnadelfeder (3) in das Gewinde gedreht werden.Ie. you have to remove the screw to the needle ( 2 ) to be able to pull out. When reinstalling the paint needle, the screw ( 1 ) against the spring force of the color needle spring ( 3 ) are turned into the thread.

Dies hat zwei Nachteile: die vorher gewählte Nadelhubeinstellung geht verloren und das Einschrauben der Hubanschlagschraube (1) gegen den Federdruck der Nadelfeder (3) ist eine unbequeme und unpraktische Handhabung.This has two disadvantages: the previously selected Nadelhubeinstellung is lost and screwing the Hubanschlagschraube ( 1 ) against the spring pressure of the needle spring ( 3 ) is an inconvenient and impractical handling.

Bei der neuen Lösung sitzt neben der Kontermutter (4) der Hubanschlagschraube (1) ein Ring (5) mit 2 Nasen (6). Dieser bildet zusammen mit dem Pistolenkörper (7) eine sich durch die Nadelfeder (3) selbst verriegelnde Bajonettkupplung.In the new solution sits next to the lock nut ( 4 ) of the stroke stop screw ( 1 ) a ring ( 5 ) with 2 noses ( 6 ). This forms together with the gun body ( 7 ) through the needle spring ( 3 ) self-locking bayonet coupling.

Diese Einheit, Hubanschlagschraube (1) mit Kontermutter (4) und dem Ring (5) kann jetzt nach leichtem Eindrücken und anschließendem Verdrehen um ca. 60° entnommen werden, ohne dass der vorher eingestellte Hubanschlag verändert wird. Das Wiedereinsetzen der Einheit geschieht in umgekehrter Reihenfolge.This unit, lifting stop screw ( 1 ) with lock nut ( 4 ) and the ring ( 5 ) can now be removed after slight impressions and subsequent turning by about 60 ° without changing the previously set stroke stop. Resetting the unit is done in reverse order.

Bei Farbspritzpistolen wird der Luftkopf (8) mittels einer Ringmutter (9) an der Pistole befestigt. Diese Methode hat zwei Nachteile

  • a) Der Kopf kommt nicht sofort in die Endposition zur Düse (10)
  • b) Das Aufschrauben der Ringmutter (meist 2 ... 3 Umdrehungen) ist zeitaufwendig.
In spray guns, the airhead ( 8th ) by means of a ring nut ( 9 ) attached to the gun. This method has two disadvantages
  • a) The head does not come immediately to the end position to the nozzle ( 10 )
  • b) Screwing on the ring nut (usually 2 ... 3 turns) is time consuming.

Die neue Lösung benutzt an Stelle des Gewindes eine Bajonettkupplung (11) in der Ringmutter. Der Kopf wird jetzt mit der Mutter zusammen sofort in die Endlage zur Düse geschoben.The new solution uses a bayonet coupling instead of the thread ( 11 ) in the ring nut. The head is now pushed together with the mother immediately in the end position to the nozzle.

Danach wird durch eine 90° Drehung der Ringmutter der Luftkopf fixiert.After that gets through a 90 ° turn the ring nut of the airhead fixed.
