BALL LOCK MOUNTING ARRANGEMENT

摘要

A paint gun assembly comprises two connected body parts, the spray head 1 and the connecting manifold 2. The spray head is provided with a bore which terminates in a radially extending space 3 of gradually increasing radius. Received in the bore is a shaft 4. The shaft has an axially extending bore which connects with radially extending bores in which balls 5 are contained. Received in the shaft is a plunger 6 which has a rounded end and which engages with the balls 5. When forced into the axial bore, the plunger 6 forces the balls 5 into the radially extending bores and out into the tapered, radially extending space 3. Engaging with the plunger 6 in the manifold body 2 is a cam 7. The cam body 7 is exposed at a surface of the manifold body 2 and includes a hexagon drive 8 by means of which the angular rotation of the cam can be adjusted using a suitable key. The manifold body further includes a recess 9 for receiving a retaining pin (not shown). The end of the retaining pin is received in the cam guide profile 10. Axial movement of the cam 7 in its housing is further resisted by compression spring 11.
