Door hinge with buffer means
The present invention relates to a door hinge which comprises: first and second housings (110, 120) which are formed in a cylindrical shape to be engaged with each other; a rotary shaft (400) installed in the first and second housings (110, 120) by a plurality of bearings (510, 520, 540) as a medium, wherein one longitudinal end on one side protrudes to the outside; a torsion spring (200) installed in the first and the second housings (110, 120) to control the torsion in accordance with the rotation of the rotary shaft (400) to serve as a door check for automatically closing the door; and a buffer means (600) placed on the outer circumference of the rotary shaft (400) and inside the first and the second housings, to reduce the rotary speed of the rotary shaft (400) by a hydraulic pressure. The door hinge with the buffer means is able to be installed on a fire wall or the like, to automatically close the door when the door is opened, to reduce the closing speed, and to prevent accidents.
본 발명은 도어 힌지에 관한 것으로, 원통형으로 이분형성되어 서로 결합되는 제 1/2하우징(110)(120), 상기 제 1/2하우징(110)(120) 내부에 복수개의 베어링(510)(520)(540)을 매개로 설치되며 일측 종단이 외부로 돌출되는 회전축(400), 상기 제 1/2하우징(110)(120)내부에 설치되어 회전축(400)의 회전에 따라 토션이 제어되어 자동으로 닫히도록 하는 도어첵 역할을 하는 토션스프링(200), 상기 회전축(400)의 외주와 제 1/2하우징 내부에 구비되며 유압에 의하여 회전축(400)의 회전속도를 늦추는 완충수단(600)으로 구성되어, 방화문 등에 설치되어 개방시 자동으로 닫히도록 하되 닫히는 속도를 늦추어 안전사고를 방지하는 완충수단을 구비한 도어힌지에 관한 것이다.
