수직형 자동 도어클로져의 유압조절장치{Hydraulic controller of vertical-type automatic doorcloser}Hydraulic controller of vertical automatic door closer {Hydraulic controller of vertical-type automatic doorcloser}

본 발명은 수직형 자동 도어클로져에 관한 것으로, 좀 더 구체적으로는 도어가 자동으로 문이 개폐되는 속도를 하우징 내부에서 유압유의 흐름속도를 제어하여 조절할 수 있도록 한 수직형 자동 도어클로져의 유입조절장치에 관한 것이다.The present invention relates to a vertical automatic door closer, and more particularly, the inflow control apparatus of the vertical automatic door closer to control the flow rate of the hydraulic oil inside the housing to control the speed at which the door automatically opens and closes the door. It is about.

도 1은 선행 기술로 본 발명인의 특허인 자동 도어클로져(특허 제263,251호)를 제품화하여 제작된 단면도로, 자동으로 문이 닫히는 속도를 제어할 수 있도록 하우징의 측면 한측에 돌출되게 형성된 유압조절바디에는 유로의 상하로 각각 조절밸브가 설치되어 하우징의 실린더실에서 피스톤이 작동시 유체가 순환시 연통되는 통로를 제어하도록 되어 있다.1 is a cross-sectional view produced by commercializing the inventor's patented automatic door closer (Patent No. 263,251) in the prior art, the hydraulic control body formed to protrude on one side of the housing so as to control the closing speed of the door automatically The control valve is installed in each of the upper and lower sides of the flow path so as to control a passage through which fluid flows when the piston is operated in the cylinder chamber of the housing.

그러나 위와 같은 선등록은 유압조절바디가 하우징의 외면에 돌출되어 있어 외관상 돌출부로 인하여 미려하지 못할 뿐만 아니라 유압조절부의 내부에 가공 및 조절밸브 등의 부품들을 추가 설치하여야 하는 등의 가공비, 부품비, 조립공수, 금형비 등의 추가로 제품의 단가를 상당히 높이는 문제점이 있다.However, the above pre-registration is not only beautiful because of the protruding part of the hydraulic control body protruding from the outer surface of the housing, but also processing cost, parts cost, assembly such as additional components such as processing and control valve should be installed inside the hydraulic control part. There is a problem in that the unit cost of the product is considerably increased by the addition of the labor and the mold cost.

또 다른 문제점은 문의 개폐되는 속도를 조절할 때 유압조절부의 상하부에 각각 설치된 조절밸브를 각각 일일히 조절하여야 하는 번거로움이 있으며, 장시간 사용시 내부 불순물 발생에 따른 유압회로의 막힘으로 정지현상이 발생되는 등의 잦은 고장이 발생하는 문제점이 있었다.Another problem is that when adjusting the speed of opening and closing the door, it is cumbersome to adjust the control valves respectively installed on the upper and lower parts of the hydraulic control unit one by one, and the stopping phenomenon occurs due to the blockage of the hydraulic circuit due to the occurrence of internal impurities when used for a long time. There was a problem of frequent failures.

본 발명의 목적은 문의 개폐되는 속도를 조절하는 유압조절기능을 하우징의 내부에 설치하여 하우징의 단순화하면서 간단한 조작으로 속도를 조절할 수 있고제조단가를 대폭적으로 절감할 수 있도록 한 수직형 자동 도어클로져의 유압조절장치를 제공함에 있다.An object of the present invention is to install a hydraulic control function to adjust the opening and closing speed of the door inside the housing of the vertical automatic door closer to simplify the housing and adjust the speed by simple operation and to significantly reduce the manufacturing cost To provide a hydraulic control device.

상기한 목적을 구현하기 위하여 제안된 본 발명은,The present invention proposed to implement the above object,

도 2는 본 발명의 설치상태를 보인 사시도이고, 도 3은 본 발명이 적용된 도어클로져의 단면도로,2 is a perspective view showing an installation state of the present invention, Figure 3 is a cross-sectional view of the door closer to which the present invention is applied,

도면부호 1은 원통형의 하우징으로 상단에 도어(20)에 체결되는 도어취부판(2)이 설치되고 하우징(1)에 축설되는 힌지축(3)에 도어프레임(30)의 취부판(4)이 설치됨과,Reference numeral 1 denotes a cylindrical housing, in which a door mounting plate 2 fastened to the door 20 is installed, and a mounting plate 4 of the door frame 30 on a hinge shaft 3 arranged in the housing 1. Is installed,

상기 힌지축(3)의 하단에 형성된 나사축(4)에 피스톤(5)이 나선결합되어 실린더실(6)에서 승하강되도록 하고 피스톤(5)은 유압 및 스프링(7)으로 탄력지지되어 도어(20)의 개폐에 따라 피스톤(5)이 실린더실(6)에서 승하강 되도록 한 것이다.The piston 5 is spirally coupled to the screw shaft 4 formed at the lower end of the hinge shaft 3 so that the cylinder 5 can be lifted and lowered in the cylinder chamber 6, and the piston 5 is elastically supported by the hydraulic pressure and the spring 7 to open the door. As the piston 20 opens and closes, the piston 5 moves up and down in the cylinder chamber 6.

한측에 볼(8)이 내재된 통로(9)를 통해 유입된 유체가 입출되도록 유로공(10)을 형성한 피스톤(5)과,A piston (5) formed with a flow path hole (10) to enter and exit the fluid introduced through the passage (9) in which the ball (8) is embedded on one side;

하우징(1)의 하단에 체결된 캡(12)에 나사결합된 조절볼트(13)에 상기 유로공(10)에 끼워지는 긴 봉형상의 속도제어봉(11)을 설치하여 조절볼트(13)의 조정에 의하여 유로공(10)을 통해 승하강되도록 한 것이다.Adjustment of the adjustment bolt 13 by installing a long rod-shaped speed control rod 11 fitted into the flow path hole 10 to the adjustment bolt 13 screwed to the cap 12 fastened to the lower end of the housing (1) By going up and down through the flow hole (10).

도 3에서와 같이 상기 속도제어봉(11)은 피스톤(5)의 상하 운동범위에서 유로공(10)을 지나는 부분에 적정각도의 테이퍼(11a)를 형성하여 속도제어봉(11)의 높이 위치에 의하여 유로공(10)과 속도제어봉(11)의 틈새(10a)가 변경되어 유체의 입출량을 조절하도록 구성한다.As shown in FIG. 3, the speed control rod 11 forms a taper 11a at an appropriate angle in a portion passing through the passage hole 10 in the vertical movement range of the piston 5 by the height position of the speed control rod 11. The clearance gap 10a of the flow path hole 10 and the speed control rod 11 is changed so as to adjust the amount of inflow and outflow of the fluid.

도 2의 도면에 위하여 본 발명의 작동상태를 살펴보면,Looking at the operating state of the present invention for the view of Figure 2,

본 발명은 도어(20)를 열면 힌지축(3)은 도어프레임(30)에 체결되는 취부판(4)에 고정상태이기 때문에 회전하지 않고 도어에 취부판(2)으로 체결된 하우징(1)이 함께 회전함에 따라 하우징(1)에 설치된 피스톤(5)이 회전시 힌지축(3)의 나선축(4)에 나사결합됨에 따라 피스톤(5)이 나선의 풀림작용으로 하강되어 실린더실(6)에 충진되어 있는 유체와 함께 스프링(7)을 밀면서 하강됨에 따라 도어가 적정힘으로 밀어 열수 있도록 되는 바,Since the hinge shaft 3 is fixed to the mounting plate 4 fastened to the door frame 30 when the door 20 is opened, the housing 1 fastened to the door by the mounting plate 2 without rotating. As the piston rotates together, the piston 5 installed in the housing 1 is screwed to the helix shaft 4 of the hinge shaft 3 when the piston 5 rotates, thereby lowering the piston 5 due to the loosening action of the spiral, and thus the cylinder chamber 6. As the door is pushed down by pushing the spring (7) together with the fluid filled in

피스톤(5)이 하강시 유체는 피스톤(5)의 한측에 형성된 통로(9)를 통하여 볼(8)이 압력에 의하여 밀리면서 유체가 올라와 피스톤(5)의 하강에 따라 확보되는 공간으로 빠져나가는 동시에 유로공(10)과 속도제어봉(11)의 틈새(10a)로 함께 빠져나가게 된다.When the piston 5 descends, the fluid is pushed by the pressure through the passage 9 formed on one side of the piston 5 and the fluid rises and exits into the space secured by the lowering of the piston 5. At the same time, the flow path 10 and the speed control rods 11 come out of the gap 10a together.

특히 하우징(1)의 하단에 속도조정봉(11)을 설치하는 조절볼트(13)를 돌려주면 테이퍼(11a)에 의한 틈새(10a)의 간격이 조정되어 도어의 닫히는 속도를 조절할 수 있게 되는 것이다.In particular, by turning the adjusting bolt 13 to install the speed adjusting rod 11 at the bottom of the housing 1 is to adjust the interval of the gap (10a) by the taper (11a) to adjust the closing speed of the door.

한편, 도어(20)를 닫으면 상기한 오픈작동의 반대작용으로 피스톤(5)이 스프링(7)의 탄성력을 받으면서 상승하게 되는데 유체가 협소한 공간을 통해 빠져나가기 때문에 도어는 일시적으로 닫히지 않고 서서히 닫히게 되는데 닫히는 속도는 상기 오픈 과정에서와 같이 조절볼트(13)의 조정으로 속도제어봉(11)의 위치변경으로 유체가 빠져나가는 틈새(10a)를 조정하여 닫히는 속도를 조정할 수 있게 되는 것이다.On the other hand, when the door 20 is closed, the piston 5 rises under the elastic force of the spring 7 due to the opposite action of the above-described open operation, but the door is gradually closed without being temporarily closed because the fluid exits through the narrow space. The closing speed is to adjust the closing speed by adjusting the clearance 10a through which the fluid escapes by changing the position of the speed control rod 11 by adjusting the adjustment bolt 13 as in the opening process.

이상과 같이 본 발명은 도어 클로져의 외형이 축소되고 단순하며 부품구성수가 적어서 협소한 공간에 설치가 용이하고 제조단가를 대폭적으로 줄일 수 있는 등 제품의 선호도 및 신뢰성을 향상시키는 효과가 있다.As described above, the present invention has an effect of improving the preference and reliability of the product, such as the appearance of the door closer is reduced and simple, and the number of parts is easy to install in a narrow space and the manufacturing cost can be greatly reduced.
