Mounting stop
A mounting stop at axially displaceable male-female couplings to prevent involuntary release of the coupling, whereby it comprises a recess ( 2 ) arranged to be placed in a first position around a shaft ( 32 ) and to be displaceable radially sidewise above said shaft ( 32 ) to a second position, and that it comprises at least one stop lug ( 6, 7; 9; 10 ) arranged, in said first position to be applied into a groove ( 34 ) and thereby to prevent an axial displacement of said male-female coupling parts towards each other, as well as a male part ( 32 ) present in such a coupling.
1. A mounting stop for axially displaceable male-female couplings to prevent involuntary release of the coupling, comprising a recess arranged to be placed in a first position around a shaft and to be displaceable radially sidewise above said shaft to a second position, and at least one stop lug arranged, in said first position to be applied into a groove and thereby to prevent an axial displacement of said male-female coupling parts towards each other, the recess of the mounting stop having on its one side a diameter corresponding to the diameter of a shaft part over which it is intended to be placed in a first position and wherein the recess of the mounting stop on its other side has a diameter which is less than the diameter of the shaft part over which it is intended to be brought in a second position, the differences in diameters between the recess parts allowing for the mounting stop to automatically return to its said first position.
2. A mounting stop according to claim 1 , wherein said at least one stop lug comprises at least two stop lugs, each of said stop lugs having a lug shaft, each of said stop lugs being arranged to the mounting stop via its lug shaft.
3. A mounting stop according to claim 2 , wherein the mounting stop is provided with a slot.
4. A mounting stop according to claim 3 , wherein said slot is arranged between said lugs shafts.
5. A mounting stop according to claim 3 , wherein said slot is arranged on the side of the mounting stop facing said stop lugs.
6. A mounting stop according to claim 3 , wherein each of said stop lugs further comprise a lug unit said lug units having an arch shape corresponding to a radius/periphery of said groove.
7. A mounting stop according to claim 6 , wherein said lug unit is provided with chamfering on its side surface facing said groove.
8. A mounting stop according to claim 6 , wherein said lug unit is provided with a radius on its side surface facing said groove.
9. A mounting stop according to claim 1 , wherein the recess of the mounting stop on its said other side is provided with a radially extending projection.
10. A male part at couplings using male-female coupling parts arranged to be brought together to a tight, dismountable coupling, comprising at least two peripherally running grooves of which a first groove is intended to receive a mounting stop according to claim 1 , and a second groove intended to receive at least one stop lug arranged to said mounting stop.
11. A male part according to claim 10 , wherein the grooves are separated by means of a projection/flange having a diameter being larger than the diameter of said first groove.
