Connection pin structure of screen shutter to induce derailment of screen in case of strong impact and reduce damage

摘要

When the present invention is directed to a connecting pin structure to induce a deviation in the event of a hard impact screen screen shutter to reduce the damage, and more particularly, to a screen to receive a strong impact due to contact of the impact, wind, objects and vehicles It relates to a connection pin arrangement in a screen shutter so that the connecting rods connecting the screen and the slider to reduce the damage of the screen by having the separation is deviation from the slider. Issues connecting pin structure of a strong screen shutter to reduce the damage induced by the deviation of the screen when the impact of the invention is raised and lowered and the screen mounting; Screen that is elevating by the winding and; A guide rail for guiding the screen and; With a wheel that slides inside the guide rail and the slider; Inserted into the lower rod pin receiving chamber formed at the both ends by elastic installation of the slider pin connection inserted into the connection pin and the pin receiving chamber connected to insert ball pin to have a force that is closely fitted squeezed pingong of the slider elastic spring on the screen in the screen shutter, including, causes the deviation from the ball taper portion pin when the taper portion shock is applied bent bottom bar is enough to be separated from the pin balls separated to form a tapered portion that gradually shaft diameter to end in the front end portion of the coupling pin and it characterized in that.;
