MID-GATE SWITCHING APPARATUS FOR A BUS SWITCHING THE GATE EASILY AND SIMPLIFIED IN ASSEMBLY STRUCTURE BY REMOVING SOME COMPONENTS

摘要

PURPOSE: A mid-gate switching apparatus for a bus is provided to reduce the components and simplify the assembly structure and switch the gate easily.;CONSTITUTION: A mid-gate switching apparatus for a bus comprises a motor, a first arm(14), a second arm(24), a third arm(26), a first and a second micro switches(34,36), and first and second switches operation cams(38). The motor is installed to one side of support frame(12). The rear part of first arm is connected to the motor shaft in the lower part of support frame. The rear part of second arm near the first arm is connected to the first arm to rotate. The third arm connected with the first arm, and second arm by hinge does a role pushing and pulling the mid-gate. First and second micro switches are installed to a rod mounted on the fixed position of the support frame side by side. The first and second micro switches shut down the applied motor current while the mid-gate switched. The first and second switches operation cams are formed into one body to be separated in the back of the second arm along the columnar direction. The first and second switches operation cams press down the first and second micro switches respectively in the backend external diameter of being fixed and coupled in the support frame.;COPYRIGHT KIPO 2012
