There are four holes in the coupling, two large ones are for nylon rods, and two small ones are for bolts. Which standard is this type of coupling? What's the name? Is it a flange coupling or a flexible pin coupling?

Is this a variation on the standard? Standardly, a nylon sleeve is added to the outside of the bolt. It is directly divided into two parts, one for the bolt and one for the nylon rod.

I feel like it’s a combination of GB/T 5843 and 5014:L

This looks like it uses an elastic diaphragm.

I understand it is also non-standard. If it has been overhauled, it is possible that the coupling hole was ground enlarged before and temporary modifications were made. :P
