Morphology
Both constituents are concrete and directly related: 'joint' means a connection and 'hinge' is a metal joint that allows movement, so 'joint hinge' transparently denotes a particular kind of hinge. This noun–noun descriptive compounding follows common cross-linguistic patterns, so a B1 learner who knows both words would readily infer the meaning.
Etymology
Joint hinge comes from the picture of two long straps joined by a pin so a door or lid can move. The word joint shows the 'connection' and hinge shows the 'turn', so the name explains a strap that keeps two parts attached while letting them 'turn'.
