Bye to all,

Today I ask you for help with a group of constraints. as you can see in the figure, this model consists of three pipes: the lower one connected via the hub to the side plates (oscillating for 15°), the one that passes inside it (blue) and must flow along the same axis, finally the flanged tube brush welded to the top cap.
the correct operation requires that the blue tube passes through the hull only when its guide which is the lower tube is perfectly vertically.
How do I make sure that the blue tube can not exceed the cap if these conditions do not occur?

thanks in advance!

I must be honest, I didn't understand the operation.
What prevents the blue piece from "enter" into the other tube if the same is not vertical?
or, if the blue piece is already inside the other tube what prevents the latter from swinging the famous 15th?

thanks to the answer,

the two tubes below are one inside the other, the blue one (which is in the bigger one that is its guide), I would like to pass through the tube above (the one welded to the cap) only in case its guide tube in which it is inserted is in vertical position, otherwise it would physically vent the cap just as in photo. Tell me if I didn't explain.
 
Sorry, but I still don't understand.
are the two tubes below solid? If one moves the other goes after him?
I'd say, otherwise how do they be one inside the other? Right?
at this point why do you have this "foundation" problem? If they tilt together then blue continues to be coaxial to others.
try to post other images, maybe coloring differently the various tubes.
 
yes the two tubes below are one concentric to the other, the outer one (blue) can only rotate by 15 degrees, the yellow one inside it is bound obviously to its 15 degrees but also can go up and down. Here I would like to create a bond that allows me to climb the yellow tube through the cap (in which the red tube is welded) only if the blue and red tube are perfectly in axis or better all three are concentric.

I'm here now.
Unfortunately, I don't think I can help you, I've never had such a need.
Maybe having the file you could do some evidence.
 
I think the solution is "contact group" :
open the tube and cap, go to the browser and select the item together1, dx button and tick on contact set (I have the English version); then select tube4000 and do the same thing.
Select now, always from the browser, together1 and tube4000 at the same time using the ctrl key keyboard; go to the inspection tab and press the activate contact solver button.
moving with the mouse the tube will see that it acquires "solidity" and stops in contact with the axieme1 .
I hope to have been clear and to have solved the problem . good evening
