Head box for subway platform screen door

摘要

The present invention provides a head box for a subway platform screen door, in which reinforcement units provides strength and elastic force to each of an upper and a lower frame inside embedded in the head box to alleviate load applied to the upper and the lower frame such that the upper and the lower frame can be stably supported, a plurality of connection units are provided between the upper and the lower frame to remarkably enhance overall strength and also to prevent deflection or twisting of the upper and the lower frame due to heavy load of a driving unit such that durability of the head box can be enhanced and the driving unit can be smoothly actuated, and vibration generated when a subway train goes into a platform is blocked not to be transferred to the head box such that bolts and nuts for fixating coupled portions of a vertical frame, the head box and the driving unit are prevented from being released because of the vibration and noises due to the vibration can be prevented.
