OIL DAMPER ALLEVIATING SWITCHING SPEED OF OPENING AND CLOSING DOOR, WHICH PREVENTS IMPACT WHEN THE DOOR IS SUDDENLY CLOSED

摘要

PURPOSE: An oil damper alleviating switching speed of opening and closing door is provided to absorb the sudden open and close of a door. ;CONSTITUTION: An oil damper alleviating switching speed of opening and closing door comprises a housing, a rotating pin and a cap part. The housing comprises a jamming protrusion(2), a space part(5), a second space part(6) and a stop(7). A jamming protrusion is formed in the outer circumference(1) to be symmetrical. The space part is filled with resistivity fluid. The stop stops the rotation when wing part approaches. The rotating pin helps the tip-end part of a wing part(12) to contact to the inner space part of the housing. The rotating pin forms a connection part(13) which can connects the upper end of a principal axis using an outside hinge. The rotating pin comprises a rotary cap part(14). The rotary cap part can cover the upper opening part of the housing with the lower of the connection part. The cap part prevents the separation of the fluid of the housing and supports the principal axis using an axis guiding hole(32).;COPYRIGHT KIPO 2011
