AI Technical Summary
In existing coagulation analyzers, the rotary arm is prone to wrap around the cable during rotation and lifting, resulting in the operation of the rotary arm being blocked, the cable being overstretched, and even equipment damage.
A rotary arm cable limiting device is designed, including a frame, a rotary device, a bearing seat, a circuit board device, a cable wire and a cable protection rotary end assembly. The cable is firmly installed on the cable protection rotary end in an S-shaped layout, and the cable protection fixed end assembly is used to limit the position to ensure that the cable does not wrap during rotation.
Through this device, the rotating arm is ensured to operate without hindering the operation within the complete 280° rotation range, avoiding excessive stretching and winding of the cable, and effectively preventing equipment damage.
