Novel cabinet doorknob transmission mechanism

The utility model relates to a novel cabinet doorknob transmission mechanism, in particular to a doorknob transmission mechanism for a metal arms locker and a safe cabinet. The novel cabinet doorknob transmission mechanism comprises a doorknob, a cylindrical gear, an assembly mechanism plate, an assembly base plate, an assembly top plate, upper and lower assembly transmission rods, upper and lower spring bolt pull rods, a lock connecting rod and a fixing wafer. The novel cabinet doorknob transmission mechanism is characterized in that the doorknob is connected with the cylindrical gear, the assembly mechanism plate is driven to move linearly in a left and right reciprocating mode by the cylindrical gear through a spur gear of the assembly mechanism plate, the upper and lower transmission rods are driven to move linearly in an up and down mode by the assembly mechanism plate, the lock connecting rod is driven to move linearly in a left and right mode, and therefore the purpose of opening and closing a door plate of a cabinet is achieved. The novel cabinet doorknob transmission mechanism is smooth and steady in transmission, simple in structure, convenient to use, and therefore the productive efficiency is improved greatly.
