The tapered ruler protrusions formed on both sides of the lower side of the presser ring held by the presser pins are inserted and clamped, and are held by the elastic force of the coil spring at the upper part of the presser pin, thereby keeping the door completely open and closed. Hydraulic adjustment can be done using a needle-tightened spring valve or a fixed needle valve. If the adjustment is completed, the nut is fixed to the fuselage by fitting the nut to the adjustment bolt to prevent the adjustment bolt from loosening during hydraulic operation, and a large oil filling tank is formed in the lower part of the outer body to prevent oil shortage during the hydraulic operation. In the event of a fire, a low melting point metal ring is inserted into the upper part of the coil spring installed in the upper part so that the door closes automatically. When the temperature rises above a certain temperature in a fire, the low melting point metal ring melts and disappears. The resilience is weakened and the door to be closed is automatically closed because the protrusion is released from the tapered groove by the resilience of the restoring spring installed in the lower part.
Description
본 발명은 유압식 자동완충 경첩에 관한 것이다. 좀 더 자세하게는 경첩의 외동체에 설치되는 회전축의 양측에 우회전 나선형 돌출캠을 형성하여 상,하 왕복작동관에 형성된 우회전 나선형 안내홈에 끼워 설치하고, 왕복작동관의 외주 양측에 좌회전 나선형 안내홈을 형성하여 외동체의 중앙부 양측에 좌측으로 경사지게 형성한 안내 돌출편이 삽입되게 설치하므로서 회전축의 회전에 따라 왕복작동관이 하강하거나, 상승할 때 왕복작동관의 하단부에 설치한 피스턴이 실린더 내에서 상, 하 왕복작동 하며서 오일을 피스턴의 상하로 이동시키게 한다. 이때 오일이 이동중에 작용하는 유압에 의하여 완충작용이 발생하여 문이 서서히 닫히도록 하는 동시에 각 부품이 충격이나 파손되는 것을 방지하고, 오일보충탱크를 크게 형성하여 공급되는 오일을 보충시켜 주어서 유압작용을 원활하게 할 수 있게한 것이다.The present invention relates to a hydraulic autobuffer hinge. In more detail, a right-turn spiral protruding cam is formed on both sides of the rotary shaft installed on the outer body of the hinge, and then inserted into a right-turn spiral guide groove formed on the upper and lower reciprocating actuating pipes, and a left-turning spiral guide groove on both outer sides of the reciprocating actuating tube. The pistons installed at the lower end of the reciprocating actuating tube when the reciprocating actuating tube descends or rises according to the rotation of the rotating shaft are installed by installing the guide protrusions formed to be inclined to the left side on both sides of the center part of the outer body. The oil is moved up and down the piston by reciprocating down and down. At this time, the buffering action occurs due to the hydraulic pressure acting while the oil is moving, and the door is closed slowly, and the parts are prevented from being shocked or damaged, and the oil supplement tank is largely formed to replenish the supplied oil. It was to make it smooth.
종래의 문제점을 해결하기 위하여 본인이 선출원한 발명특허출원 1998년 제31398호는 경첩의 외동체에 설치되는 회전축의 양측에 우회전 나선형 돌출캠을 형성하여 왕복작동관에 형성된 우회전 나선형 안내홈에 끼워 설치하고, 왕복작동관의 외주 양측에 좌회전 나선형 안내홈을 형성하여 외동체에 설치한 고정관의 하부 양측에 좌측으로 경사지게 형성한 안내 돌출편이 삽입되게 설치하므로서 회전축의 회전에 따라 왕복작동관이 하강하거나, 상승할 때 왕복작동관의 하단부에 설치한 피스턴이 실린더 내에서 상, 하 왕복작동 하며서 오일을 피스턴의 상, 하로 이동시키게 하여 오일이 이동중에 작용하는 유압에 의하여 완충작용이 발생하여 문이 서서히 닫히도록 하는 과정에서 문이 완전하게 열리거나, 닫힌 상태를 유지시켜주는 괘지핀이 충격을 받아 파손되는 예가 허다하고 오일 보충탱크가 적어 유압실린더에 공급되는 오일의 량이 부족현상이 발생하여 완충작용을 원활하게할 수 없었고, 특히 유압조절 니들밸브가 작동중에 이완되어 완충작용을 원활하게 이루어지지 않는 등 의 문제점이 있었다.In order to solve the conventional problems, the invention patent application No. 31398, which was previously filed by the applicant, is formed by inserting a right-turn spiral protruding cam on both sides of a rotating shaft installed on the outer body of the hinge and inserting it into a right-turning spiral guide groove formed in the reciprocating operation tube. The reciprocating actuation tube is lowered according to the rotation of the rotating shaft by forming a left turn spiral guide groove formed on both outer circumferences of the reciprocating actuation tube so that the guide protrusions inclined to the left are inserted on both lower sides of the fixed tube installed on the outer body. When rising, the piston installed at the lower end of the reciprocating pipe reciprocates up and down in the cylinder to move the oil up and down the piston so that the oil is absorbed by the hydraulic pressure acting during the movement and the door closes slowly. In the process of opening the door, the door pin is completely opened or the locking pin that keeps the door closed. There are many cases of breakage and the oil filling tank is so small that the amount of oil supplied to the hydraulic cylinder is insufficient, and the buffering action cannot be smoothed.In particular, the hydraulic control needle valve is loosened during operation and the buffering action is not smoothly performed. There was a problem.
본 발명은 이와 같은 문제점을 해소하게 위하여 경첩 외동체에 설치되는 회전축의 양측에 우회전 나선형 돌출캠을 형성하여 상, 하 왕복작동관에 형성된 우회전 나선형 안내홈에 끼워 설치하고, 왕복작동관의 외주 양측에 좌회전 나선형 안내홈을 형성하여 외동체의 중앙부 양측에 좌측으로 경사지게 형성한 안내 돌출편이 삽입되게 설치하므로서 회전축의 회전에 따라 왕복작동관이 하강하거나, 상승할 때 왕복작동관의 하단부에 설치한 피스턴이 실린더 내에서 상, 하 왕복작동 하며서 오일을 피스턴의 상하로 이동시키게 하고, 외동체 상부에 설치되는 회전축에 종으로 형성된 요철부와 요철부로 맞물림시킨 연결링의 외주에 종으로 형성한 요철부에 맞물려 연결되게 캡의 내부 중앙에 종으로 요철부를 형성하며, 지지관의 상면에 테이퍼진 괘지홈을 양측에 형성하여 여기에 연결링의 상부에서 압지핀을 상, 하 유동되게 박아 이 압지핀에 의하여 압지되는 압지링의 하부 양측에 형성된 테이퍼진 괘지돌기를 삽입 괘지되게 하고, 압지핀의 상부에서 코일스프링의 탄발력에 의하여 압지시키므로서 문이 완전히 열린 상태와 닫힌 상태를 유지시키며, 유압조절은 스프링으로 탄지시킨 니들밸브를 사용하거나, 고정 니들밸브를 사요할 수 있으나, 조정이 완전히 이어진 경우에는 조정 보울트에 너트를 나합시켜 동체에 고정시키므로서 유압작동중에 조정보울트가 이완되어 유압작용이 원활하게 되지 않는 것을 방지하며, 유압작동중에 오일이 부족한 것을 방지하기 위하여 동체하부에 오일보충탱크를 크게 형성한다. 그리고 화재 발생시에는 문이 자동으로 닫히게 하기 위하여 저융점 금속링을 코일스프링의 상부에 삽입시켜 화재시에 일정온도 이상으로 상승되면 저융점 금속링이 용융되어 없어지므로서 코일스프링의 탄발력이 극히 약화되므로 테이퍼진 괘지홈에서 괘지돌기가 이탈되면서 닫히려는 문이 자동으로 닫히게 하기 위한것이다The present invention forms a right turn spiral protruding cam on both sides of the rotary shaft to be installed on the hinge outer body in order to solve this problem, installed in the right turn spiral guide groove formed in the upper and lower reciprocating operation pipe, both sides of the outer circumference of the reciprocating operation pipe Pistons installed at the lower end of the reciprocating actuation tube when the reciprocating actuation tube descends or ascends in accordance with the rotation of the rotating shaft by installing a left turn helical guide groove formed therein so that the guide protrusions inclined to the left are inserted at both sides of the central portion of the outer body. In this cylinder, the oil is moved up and down in the piston by reciprocating up and down, and the irregularities formed longitudinally on the outer circumference of the connecting ring interlocked with the irregularities formed by the bell on the rotary shaft installed in the upper part of the outer body. Grooved grooves tapered on the upper surface of the support pipe to form concave-convex portions in the center of the cap so as to be engaged. It is formed on both sides and the push pins are driven up and down from the upper part of the connection ring, and the tapered bumps formed on both sides of the lower part of the press ring being pressed by the push pins are inserted into the pins, and the coil is placed on the top of the push pins. The door is kept fully open and closed by being pushed by the spring force, and the hydraulic control may use a spring-loaded needle valve or a fixed needle valve, but if the adjustment is completed By fitting the nut to the bolt and fixing it to the fuselage, the adjustment bolt is loosened during the hydraulic operation to prevent the hydraulic operation from being smooth, and the oil refill tank is largely formed under the fuselage to prevent oil shortage during the hydraulic operation. . In order to close the door automatically in case of fire, insert the low melting point metal ring on the upper part of the coil spring, and when the fire rises above a certain temperature, the low melting point metal ring will melt and disappear, and the elasticity of the coil spring will be extremely weak. This is to allow the door to be closed automatically as the ruler is separated from the tapered ruler groove.

A hydraulic pressure adjusting needle valve 32 which is formed larger than the body 11 and forms an oil outlet 22 communicating with the cylinder 12 at the lower side and which is held by the coil spring 31 in the tubular adjustment bolt 30 is installed. Alternatively, the flow control needle valve 32a fixed directly to the adjustment bolt 30a is installed and screwed with a nut 30b to be fixed to the outer body 11. Here 22a is a distribution channel. In this way, in the case where shock hydraulic pressure occurs in the cylinder 12 by forming the oil passage, in the case of installing the hydraulic control needle valve 32 held by the coil spring 31 on the adjustment bolt 30, the flow path is largely opened to cushion the action. Let's do it. Then, the oil leakage stopper 33 is screwed into the lower end of the outer body 11, and the recessed part 33a is formed inside the leakage stopper 33 to insert and install the permanent magnet 33b. It collects iron particles in the flow and keeps oil clean all the time. A guide protrusion 13 inclined to the left side is formed on both sides of the inner center of the outer body 11, and a spiral guide groove 14 which rotates leftward on both sides of the outer periphery and spiral guide grooves 15 which turn right on both sides of the inner circumference are formed.

On the contrary, when the door is closed, the door is closed by the resilient force of the restored coil spring 61, and the rotating shaft 40 connected and fixed by the connection ring 65 inside the upper cap 60 rotates in the opposite direction. While the reciprocating actuation tube 16 is lowered by the right turning spiral protruding cam 41 inserted into the right turning spiral guide groove 15, when the piston 17 descends, hydraulic pressure is generated in the cylinder 12 to adjust the oil. Through the hydraulic pressure adjusting needle valve 32 is moved to the upper portion of the piston 17 through the oil outlet 22 and the "[" type flow path 20 of the oil supplement tank 21. In this way, the oil is buffered by the hydraulic pressure in the flow process is the door is closed slowly. In the course of this operation, the piston 17 may continue to descend to block the "[" type flow path 20 and the oil outlet 22 at the same time. At this moment, the door stops closing momentarily. When the oil in the cylinder 12 flows between the clearance between the cylinder 12 and the piston 17 by the elasticity of the restoring coil spring 61 in the stopped process, the "[" type flow path 20 is opened. Since the hydraulic pressure is hardly acted on, the door is momentarily accelerated by the elasticity of the restoring coil spring 61 so as to close at a high speed so as to be locked in the locking device installed in the door frame.
