Low resistance roll composite gauge mechanism

Abstract

This application discloses a low-resistance winding composite instrument mechanism, relating to the field of unwinding mechanisms. It includes a rotating rod with a resistance-reducing component for lowering unwinding resistance. The resistance-reducing component includes a first fixed plate fixedly connected to the rotating rod. This application utilizes the cooperative arrangement of the first fixed plate, a second fixed plate, and conical cylinders. In use, the winding tape is sleeved on the rotating rod, and then the second fixed plate is sleeved on the rotating rod. A pushing component pushes the second fixed plate closer to the first fixed plate, causing the winding tape to move and allowing both conical cylinders to insert into the inner diameter of the winding tape. Then, a fixing component secures the second fixed plate, preventing contact between the winding tape and the first and second fixed plates, thus reducing resistance and minimizing contact between the winding tape and the transparent plastic plates on both sides, which would increase resistance.
