<p>A headbox locking device of a screen door is provided to simplify easy maintenance and repair work by allowing the door to be opened by one-step operation applying rotational force to a key front, and to save maintenance and repair costs by reducing breakdown frequency. A headbox locking device of a screen door(20) comprises a frame(40), a key operating portion(50) and an opening/closing seesaw(60). The frame is fixed to a predetermined position of a body(10). The key operating portion is fixed to the frame, and the other end thereof moves back and forth by rotation of one end thereof. The opening/closing seesaw is hinged with the frame, driven by the key operating portion, provided with a locking roller(64) in an end of one side, and mounted in a locking portion(22) formed in the door, thereby allowing opening/closing of the door to be possible.</p> |
