How to make THIS simple clamp work?

[trpastor]

Hey guys - I have personal project I'm working on. I'm NO engineer, so I apologize for my horrible terminology and ignorance in advance. But I was hoping someone here could help me.

I'm trying to create a quick clamp instead of using thumb screws on something, so make it faster and easier.

currently, in my application, object A slides onto a tube or rod (object C) which is secured to object B.

Traditionally I use thumbscrews to tighten down into the T nuts on object A, and then take them off when I'm done. Not a big deal, but I thought I could make an object that could save me some time

I was thinking instead of bolts, I could take a bolt and put a notch in it (as shown Object D). then I could make a clamp that has a pin in between the sides or frame, that could HOOK onto the notch, and then clamp down. I would have the outside arc of this clamp be further in relation to the pin (or axis) so that it forces it down and wouldn't want to go past the peak tension point of the arc

Basically like Masons jar.

What I'm thinking before I try to make this, is that i need some suspension in it, so that when the clamp is locked down there is tension or pressure between the clamp and object B, to form a tight bond.

Is this true?

are there any other simple ideas that would work to accomplish this task?
thanks!

Have you looked into Dzus fasteners? I think that some variation of that might suit your purpose quite well.

It's called a cam lever clamp. Google that term and I think you'll probably find something that suites your needs.

Great! Thank you guys. I think with that keyword I can find an application I can reshape a bit
thanks!

Let us know how it works out. If you don't resolve it, we'll still be here.

Just a FYI: You will find those cam lever clamps are very commonly used on bicycles. Particularly the front and back wheels will have ones that are about 4-6" long, and the seat post clamp will have one that's about 1.5" to 2.5" long.

My advice would be to pass by your local bicycle shop, and ask the guys who do repairs if they have a bin of "Quick Release Skewers"

That's the easiest way to get your hands on some to see if they'll work for you.

Carr-lane has clamps similar to if not exactly like your picture.
