도어 클로저Door closer

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도, 제2도는 본 발명에 의한 도어 클로저의 일실시 예를 도시한 별단면에 있어서의 각 종단면도, 제3도는 동 실시예의 분해 사시도.1 and 2 are each longitudinal cross-sectional view in a separate cross-sectional view showing one embodiment of the door closer according to the present invention, Figure 3 is an exploded perspective view of the embodiment.

Claims (1)

본체케이스내의 상단이 뚜껑으로 밀폐되는 내통을 그 중앙부에 있어 중공의 축받이를 고정개재하여 이것에 축지된 회전축에 의하여 한쌍의 실로 구획하고, 이 양실에 상기 회전축으로부터 돌설되고 주위 방향에 역지 변부설통로가 관통되어서 된 한쌍의 회전익이 회전자재하도록 내장됨과 함께 고점성류채가 충진되고, 상기 회전축의 일방향에 복귀용 스프링으로 가세 되고 있는 동시에 상기 본체케이스의 저부에는 조절나사가 조절변을 상하동하게 하되, 하방향으로 조절스프링으로 가세된 상태로서 나합되고, 상기 축받이와 회전축과의 상기 한쌍의 실의 양 고압실 상호 및 양 저압실상호를 연통하여 각각 설치한 하부통로와 상부통로를 연통하도록 상기 축받이 내벽면과 상기 조절변과의 사이에 통로가 형성되고 당해 통로가 상기 하부통로로부터 축받이내에 유입하는 고점성류채의 압력과 상기 조절스프링력과의 힘관계에 의한조절변의 응동에 의하여 광협자재하게 자동 조절되도록한 것을 특징으로 하는 도어클로저.The inner cylinder in which the upper end of the main body case is sealed with a lid is divided into a pair of threads by a rotating shaft axially fixed through a hollow bearing, and the two chambers are protruded from the rotating shaft and are bounded in the circumferential direction. While a pair of rotary blades through which the rotor blades are built to rotate, the high viscous lubricator is filled, and the spring is added as a return spring in one direction of the rotating shaft, and at the same time, the adjustment screw is moved up and down on the bottom of the body case. Into the bearing so as to communicate with the lower passage and the upper passage respectively installed in a state of being added to the adjustment spring in the downward direction, and communicate with each other between the high-pressure chamber and the two low-pressure chamber of the pair of threads between the bearing and the rotating shaft. A passage is formed between the wall and the control valve, and the passage is from the lower passage. The door closer characterized in that it is automatically adjusted in a wide range by the response of the control valve by the force relationship between the pressure of the high viscous lubricating material flowing into the bearing and the control spring force. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
