본 고안은 카세트 도어 개폐 동작시에 도어의 급격한 개폐를 방지하기 위한 댐퍼 장치에 관한 것으로 특히, 나사결합 되는 두 개의 원통체내에 상대적으로 작용하는 스프링을 마주 설치하여된 카세트 도어 댐퍼 장치에 관한 것이다.The present invention relates to a damper device for preventing the sudden opening and closing of the door during the cassette door opening and closing operation, and more particularly, to a cassette door damper device that is installed to face the spring relatively acts in the two cylindrical bodies to be screwed.
종래에는 제 2 도에 도시된 바와 같이 카세트 도어측에 연결되는 연결고리(30)의 축종단부에 패킹(31)를 끼우고 이 패킹(31)을 원통체(32)내에 삽입한 후 원통체(32)의 타측 종단부에 나사(33)를 설치하여 패킹(31)이 원통체(32)내에서 이동할 때 원통체내로의 공기 공급량 또는 원통체 외부로 공기가 배출되는 공기 유출량을 조절하도록 구성되어 있고, 이러한 종래 댐퍼의 사용은 원통체(32)를 카세트 몸체에 고정하고 카세트 도어에는 연결고리(30)를 연결하여 도어를 개폐하면 패킹(31)이 원통체(32)의 내벽에 마찰되는 마찰력과 패킹(31)이 원통체 내부에서 이동될 때 원통체 내부에서 발생되는 흡인력에 의하여 도어의 개폐 속도가 조절되는 것이나 연결고리(30)의 축에 패킹(31)을 끼울 때 강제적으로 끼우기 때문에 패킹(31)의 접촉으로 접촉저항을 얻고 있으므로 도어의 개폐시마다 패킹(31)의 마모가 생기게 될뿐 아니라 이렇게 마모된 패킹의 부스러기돌이 패킹(31)과 원통체(32)사이에 끼워져서 작동불능이 되어 댐퍼로서의 기능을 제대로 발휘하지 못하는 단점이 있었다.Conventionally, as shown in FIG. 2, the packing 31 is inserted into the shaft end of the connecting ring 30 connected to the cassette door side, and the packing 31 is inserted into the cylindrical body 32, and then the cylindrical body ( The screw 33 is installed at the other end of the 32 to adjust the amount of air supplied into the cylindrical body or the amount of air flowing out of the cylindrical body when the packing 31 moves in the cylindrical body 32. And, the use of such a conventional damper is fixed to the cylinder body 32 and the cassette door is connected to the connecting ring 30 to open and close the door friction force that the packing 31 friction with the inner wall of the cylindrical body (32) When the packing 31 is moved inside the cylinder, the opening and closing speed of the door is controlled by the suction force generated inside the cylinder, or the packing 31 is forcibly inserted when the packing 31 is inserted into the shaft of the connecting ring 30. Contact resistance is obtained by the contact of 31. Not only does the wear of the packing 31 occur every time the door is opened or closed, but the defects of the worn packing between the packing 31 and the cylindrical body 32 become inoperable and do not function properly as a damper. there was.
본 고안은 이러한 종래의 단점을 해결하기 위하여 나사 결합되는 두 개의 원통체 내에 상대적으로 작용을 하는 2개의 스프링을 마주설치하여 패킹을 사용하지 않으므로 패킹의 마모등에서 오는 단점을 해결할 수 있을 뿐 아니라 외부에서 이물질이 원통체내에 삽입되는 것을 방지할 수 있어 사용 수명이 길게되며, 조립작업률이 향상되는 카세트 도어 댐퍼 장치를 제공하는 것을 목적으로 하는 것으로, 이하 첨부된 도면을 참조하면서 본 고안의 구성 및 작용효과를 설명하면 다음과 같다.In order to solve the above disadvantages, the present invention does not use the packing by installing two springs which are relatively in two cylindrical bodies that are screwed together, so that the disadvantages of the wear of the packing can be solved, It is an object of the present invention to provide a cassette door damper device which can prevent the foreign matter from being inserted into the cylindrical body and thus has a long service life and improves the assembly work rate. When described as follows.
제 1 도를 참조하면 본 고안 장치의 구성은, 고리(1)가 일단에 형성된 축봉(2)을 제 1 원통체(3)에 끼우고, 압축코일 스프링(4)과 고정링(5)을 축봉(1)에 끼워 제 1 원통체(3)내에 압축 코일 스프링(4)을 위치 시키며 제 1 원통코일 스프링(4)과 고정링(5)을 축봉(1)에 끼워 제 1 원통체(3)내에 압축 코일 스프링(4)을 위치 시키며 제 1 원통체(3)의 외측단부와 제 2 원통체(6)의 내측에는 나사부(7)를 형성하여 제 1 원통체(3)를 제 2 원통체(6)에 끼우고, 제 2 원통체(6)내에는 압축코일 스프링(8)을 설치하여 축봉(2)의 고정링(5)과 제 2 원통체(6)의 벽면(6')사이에 탄지되도록 하여된 것으로서, 여기에서 미설명 부호 9 : 압축코일 스프링(8)의 위치를 고정하기 위한 핀, 10 : 카세트 도어, 11 : 돌출봉 12 : 체결나사이다.Referring to FIG. 1, a constitution of the device of the present invention includes a shaft 1 formed at one end of a ring 1 in a first cylindrical body 3, and a compression coil spring 4 and a fixing ring 5. The compression coil spring 4 is positioned in the first cylindrical body 3 by being fitted to the shaft 1, and the first cylindrical body 3 is fitted by fitting the first cylindrical coil spring 4 and the retaining ring 5 to the shaft 1. The compression coil spring (4) is positioned inside the outer cylindrical end of the first cylindrical body (3) and the inside of the second cylindrical body (6) to form a screw portion (7) to form the first cylindrical body (3) to the second cylinder. Inserted into the sieve 6, the second cylindrical body 6 is provided with a compression coil spring (8) so that the fixing ring (5) of the shaft (2) and the wall surface (6 ') of the second cylindrical body (6) Herein, the reference numeral 9 is a pin for fixing the position of the compression coil spring 8, a cassette door, and 11 a protruding rod 12 and a fastening screw.
이러한 본 고안 장치의 작용효과를 설명하기 전에 본 고안 장치의 조립과정을 살펴보면 축봉(2)을 제 1 원통체(3)의 측벽부(3')에 형성된 구멍(3")을 통하여 삽입한후 압축코일 스프링(4)을 축봉(2)에 끼우고 다시 고정링(5)을 축봉(1)에 끼워 고정하게 되면 압축코일 스프링(4)과 축봉(2)은 제 1 원통체(3)에서 분리되지 않게 된다.Before explaining the effect of the device of the present invention, look at the assembly process of the device of the present invention after inserting the shaft (2) through the hole (3 ") formed in the side wall portion (3 ') of the first cylindrical body (3) When the compression coil spring (4) is inserted into the shaft bar (2) and the retaining ring (5) is inserted into the shaft bar (1) to fix the compression coil spring (4) and the shaft bar (2) at the first cylindrical body (3) It will not be separated.
왜냐하면 고정링(5)의 직경은 원통체(3)의 내경보다 작고 압축코일 스프링(4, 8)의 직경보다 크기 때문이다.This is because the diameter of the retaining ring 5 is smaller than the inner diameter of the cylindrical body 3 and larger than the diameter of the compression coil springs 4, 8.
또한 제 2 원통체(6)의 내부에는 압축 코일 스프링(8)이 설치되어 있고, 축봉(2)의 최종단부에 설치된 핀(9)이 압축코일 스프링(8)의 중앙에 삽입되도록 제 1 원통체(3)의 나사부(7)를 제 2원통체(6)의 나사부(7)이 끼우면 조립이 완료된다.In addition, a compression coil spring 8 is provided inside the second cylindrical body 6, and the first cylinder is inserted into the center of the compression coil spring 8 so that the pin 9 provided at the last end of the shaft bar 2 is inserted. The assembly is completed when the threaded portion 7 of the sieve 3 is fitted with the threaded portion 7 of the second cylindrical body 6.
이 상태에서 제 1 도에서와 같이 축봉(2)의 고리(1)의 구멍에 카세트 도어(10)의 일측면에 형성되는 동시에 끝단이 나사산을 갖는 돌출봉(11)을 끼운후 나사(12)로서 체결하고, 제 2 원통체(6)를 도시 생략된 카세트 몸체에 고정한후 카세트 도어(10)를 열게되면 카세트 도어(10)의 이동에 따라서 고정링(5)은 제 1 원통체(3)측으로 당겨지는 동시에 고정링(5)은 압축코일 스프링(4)을 압축하게 되므로 카세트 도어의 개방시 개방되는 방향에 압축코일 스프링(4)의 탄발력이 반대로 가해져서 카세트 도어(10)는 부드럽게 개방된다.In this state, as shown in FIG. 1, the screw 12 is formed in one side of the cassette door 10 in the hole of the ring 1 of the shaft 2, and at the same time, inserts the protruding rod 11 having a threaded end. When the second cylindrical body 6 is fixed to the cassette body (not shown) and the cassette door 10 is opened, the fixing ring 5 is moved to the first cylindrical body 3 according to the movement of the cassette door 10. At the same time, the fixing ring 5 compresses the compression coil spring 4 while being pulled to the side, and the elastic force of the compression coil spring 4 is applied to the opening direction at the time of opening the cassette door so that the cassette door 10 is opened smoothly. do.
이때 압축코일 스프링(8)은 스프링(4)의 탄발력보다 약하므로 밀어 주는 힘은 미약하다.At this time, since the compression coil spring 8 is weaker than the spring force of the spring 4, the pushing force is weak.
이렇게 개방된 카세트 도어(10)를 닫게 되면 고정링(5)은 제 2 원통체(6)측으로 밀리게 됨과 동시에 탄발력이 약한 압축코일 스프링(8)을 서서히 압축하게 되어 카세트 도어(10)가 닫히는 방향으로 압축코일 스프링(4)의 스프링 탄발력이 반대로 스므스하게 가해지므로 카세트 도어(10)가 부드럽게 닫히는 것이다.When the cassette door 10 opened in this way is closed, the fixing ring 5 is pushed toward the second cylindrical body 6 and at the same time, the cassette coil 10 is gradually compressed by compressing the compression coil spring 8 having weak elasticity. Since the spring spring force of the compression coil spring 4 is applied smoothly in the closing direction, the cassette door 10 is smoothly closed.
또한 카세트 도어의 개폐 속도는 제 1 원통체(3)와 제 2 원통체(6)의 나사부(7)체결 깊이의 조절에 따라 결합된 원통체(3, 6)전체의 길이를 조절함으로써 압축코일 스프(4, 8)의 스프링 탄발력이 변화됨을 이용하여 조절할 수 있는 것이다.In addition, the opening / closing speed of the cassette door is controlled by adjusting the length of the combined cylindrical bodies 3 and 6 in accordance with the adjustment of the screwing depth of the first cylindrical body 3 and the second cylindrical body 6. The spring elasticity of the soup (4, 8) can be adjusted by using a change.
또한, 고정링(5)은 압축코일 스프링(4, 8)사이에서 스프링의 인장력을 조절하는 중간 역할을 수행하는 것이다.In addition, the retaining ring (5) is to play an intermediate role of adjusting the tension force of the spring between the compression coil spring (4, 8).
이상에서 설명한 바와 같이 본 고안에 의하면 조립과정이 단순히 끼우고 나사결합하는 것이므로 부품의 파손등이 없어 조립공정의 작업 효율을 개설할 수 있고, 댐퍼 작용이 스프링 탄발력을 이용하는 동시에 제 1, 제 2 원통체(3, 6)가 상호 나사 결합되어 있어 외부에서 이물질이 제 1, 제 2 원통체(3, 6)내부로의 유입을 방지하여 사용 수명이 연장된다.As described above, according to the present invention, the assembling process is simply inserted and screwed together, so there is no breakage of parts, so the work efficiency of the assembling process can be outlined, and the damper action uses the spring force and at the same time, the first and the second. Cylindrical bodies 3 and 6 are screwed together to prevent foreign matter from flowing into the first and second cylindrical bodies 3 and 6 from the outside, thereby extending the service life.
