The bushing 34 made of a material having a hardness lower than) is easily worn, and a gap greater than or equal to a predetermined value is generated between the bushing 34 and the connecting pin 33. As a result, the swinging arm 30 is fixed to the arm 31. There was a problem that the vibration and noise is generated between the link portion 32 and the connecting pin 33 of the swinging arm 30 when the relative movement with respect to each other.

이에 본 고안은 상기와 같은 문제점을 해소시켜 주기 위해 안출된 것으로, 요동아암의 링크부와 고정아암을 연결시켜주는 연결핀 사이에 설치된 부싱이 요동아암의 작동에 따라 마모되어지게 되면 외부에서 간단한 조작을 해줌으로써 상기 부싱이 마모된 정도만큼 보상해주어 상기 링크부의 내주면과 연결핀의 외주면 사이에 항상 일정한 마찰력이 유지되도록 하여, 이상 진통과 소음이 발생하지 않도록 한 요동기구의 관절연결구를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and the bushing installed between the linking portion of the swinging arm and the connecting pin connecting the fixed arm is worn out by the swinging arm, and thus simple operation from the outside. Compensating the bushings by the amount of wear to ensure that a constant frictional force is always maintained between the inner peripheral surface of the link portion and the outer peripheral surface of the connecting pin, to provide a joint connector of the swinging mechanism to prevent abnormal pain and noise There is this.

이러한 목적을 달성하기 위한 본 고안은, 고정아암에 대해 연결핀을 매개로 요동하도록 연결된 요동아암의 링크부내면 양쪽끝부분에다 바깥쪽을 향해 경사진 제1부싱을 각각 1개씩 고정설치해 주고, 상기 연결핀의 한쪽은 상기 부싱의 경사면에 대응되도록 경사지게 형성시켜주는 한편 그 나머지쪽은 축방향으로는 미끄럼이동하지만 회전방향으로는 회전되지 않고 상기 부싱의 경사면에 대응하도록 경사지게 형성된 제2부싱을 설치해서, 이 제2부싱의 바깥쪽에 설치된 너트의 조임정도에 따라 제2부싱이 축방향으로 이동되어져 상기 요동아암의 링크부 내면에 고정설치된 제1부싱에 대한 연결핀의 경사면과 제2부싱의 경사면의 접촉상태를 조정하도록 되어 있다.The present invention for achieving this purpose, and fixed to each of the first bushing inclined outward at both ends of the inner surface of the link portion of the swinging arm connected to the rocking arm via the connecting pin to the fixed arm, One side of the pin is formed to be inclined to correspond to the inclined surface of the bushing, while the other side is provided with a second bushing formed to be inclined to correspond to the inclined surface of the bushing while sliding in the axial direction but not rotated in the rotational direction. The second bushing is moved in the axial direction according to the tightness of the nut installed on the outer side of the second bushing so that the inclined surface of the connecting pin and the inclined surface of the second bushing are fixed to the inner surface of the linking portion of the swinging arm. It is supposed to adjust the status.

이하 본 고안을 첨부한 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 고정아암(1)에 대해 연결핀(2)과 링크부(3)를 매개로 요동아암(4)이 설치되면서, 링크부(3)의 내면 양쪽에는 각각 바깥쪽을 향해 경사진 경사면(5a, 5b)을 갖춘 제1부싱(6a, 6b)들이 고정설치되고, 상기 연결핀(2)은 그 한쪽이 상기 제1부싱(6a)의 경사면(5a)에 대응하도록 경사지게 형성된 경사부(7)와 이 경사부(7)로부터 일정한 직경을 갖추면서 고정아암(1)의 바깥쪽으로 돌출되도록 뻗어진 연장부(8)를 구비하고, 상기 연결핀(2)의 연장부(8)쪽 끝에는 키이(9)를 매개로 제2부싱(10)이 고정설치된 구조로 되어 있다.The present invention is the inclined surface inclined toward the outside on both sides of the inner surface of the link portion (3) while the swinging arm (4) is installed via the connecting pin (2) and the link portion (3) with respect to the fixed arm (1) First bushings 6a and 6b having 5a and 5b are fixedly installed, and the connecting pin 2 has an inclined portion formed such that one side thereof is inclined to correspond to the inclined surface 5a of the first bushing 6a ( 7) and an extension portion 8 extending from the inclined portion 7 so as to protrude outward from the fixed arm 1, and at the end of the extension portion 8 of the connecting pin 2; The second bushing 10 is fixedly installed via the key 9.

여기서 상기 제2부싱(10)은 그 한쪽이 상기 제1부싱(6b)의 경사면(5b)과 대응하는 경사면(10a)을 갖추고 다른쪽끝은 고정아암(1)의 바깥으로 연장되어져 있으며, 또 이 고정아암(1)의 바깥쪽으로 뻗어있는 연장부(8)의 제2부싱(10)뒤에는 와셔(11)를 사이에 두고 너트(12)가 나사체결 되어져 있다.Here, the second bushing 10 has one inclined surface 10a corresponding to the inclined surface 5b of the first bushing 6b and the other end thereof extends out of the fixed arm 1. The nut 12 is screwed behind the second bushing 10 of the extension 8 extending outward of the fixed arm 1 with the washer 11 therebetween.

또한 연결핀(2)의 경사부(7)쪽 역시 고정아암(1)의 바깥쪽으로 연장되어 이 고정아암(1)으로부터 돌출된 돌출부(13)에 의해 고정핀(14)으로 연결고정되어 고정아암(1)과 연결핀(2)이 일체가 되어 함께 회전하도록 설치되어 있다.In addition, the inclined portion 7 side of the connecting pin 2 also extends to the outside of the fixed arm 1 and is connected and fixed to the fixed pin 14 by the protrusion 13 protruding from the fixed arm 1. (1) and the connecting pin (2) are integrally provided so as to rotate together.

이하 본 고안의 작용 및 효과를 설명한다.Hereinafter will be described the operation and effect of the present invention.

상기와 같이 구성된 본 고안의 관절연결구는, 고정아암(1)에 대해 요동아암(4)의 연결핀(2)을 중심으로 회전하게되면, 요동아암(4)의 링크부(3)안쪽내면에 고정설치된 제1부싱(6a, 6b)의 경사면(5a, 5b)이 연결핀(2)의 경사부(7)표면과 제2부싱(10)의 경사면(10a)에 맞닿아 면접촉하면서 요동아암(4)에 적절한 마찰력을 부여해 주게 된다.The joint connector of the present invention configured as described above, when rotated about the connecting pin (2) of the swinging arm (4) with respect to the fixed arm (1), on the inner inner surface of the link portion (3) of the swinging arm (4) The inclined surfaces 5a and 5b of the fixed first bushings 6a and 6b abut the surface of the inclined portion 7 of the connecting pin 2 and the inclined surface 10a of the second bushing 10 while being in surface contact with the swing arm. The appropriate frictional force is given to (4).

물론 이때 요동아암(4)의 요동운동은 도시되지 않은 다른 기구에 의해 이루어지게 된다.Of course, the swinging motion of the swinging arm 4 is made by another mechanism not shown.

이와같이 제1부싱(6a, 6b)과 제2부싱(10) 및 연결핀(2)의 경사부(7)가 서로 맞닿아 면접촉하면서 요동아암(4)이 반복적인 요동운동을 되풀이하게 하면, 연결핀(2)보다 경도가 낮은 재질로 된 부싱(6a, 6b, 10)이 마찰에 의해 마모되어지게 되고, 이 부싱(6a, 6b, 6c)의 마모도가 증가하게 되면 제1부싱(6a, 6b)과 연결핀(2)의 경사부(7) 및 제2부싱(10) 사이의 간격이 점점 증가되어져 요동아암(4)이 움직이면서 진동과 소음이 발생하게 된다. 이때 연결핀(2)의 연장부(8)쪽 끝에 나사 결합되어져 있는 너트(12)를 안쪽으로 조여줌으로서 제2부싱(10)이 밀려 화살표(15)쪽으로 이동되어 제2부싱(10)이 경사면(10a)과 제1부싱(6b)의 경사면(5b)이 서로 긴밀히 밀착되어지도록 해서 부싱의 마모량을 보충해 주게 된다.When the first bushings 6a and 6b and the second bushing 10 and the inclined portion 7 of the connecting pin 2 come into contact with each other and are in surface contact with each other, the swing arm 4 repeatedly repeats the swinging motion. The bushings 6a, 6b, and 10 made of a material having a lower hardness than the connecting pin 2 are worn out by friction, and when the degree of wear of the bushings 6a, 6b, and 6c increases, the first bushing 6a, 6b) and the interval between the inclined portion 7 and the second bushing 10 of the connecting pin 2 is gradually increased to generate the vibration and noise as the swinging arm 4 moves. At this time, the second bushing 10 is pushed toward the arrow 15 by tightening the nut 12 which is screwed in at the end of the extension part 8 of the connecting pin 2, and the second bushing 10 is moved. The inclined surface 10a and the inclined surface 5b of the first bushing 6b are brought into close contact with each other to compensate for the amount of wear of the bushing.

이때 연결핀(2)의 경사부(7)쪽에 있는 제1부싱(6a)은 제2부싱(10)의 다른쪽의 제1부싱(6b)을 밀어주게 되어 요동아암(3)이 요동운동을 하면서 적절히 이동되어져, 양쪽의 제1부싱(6a, 6b)이 연결핀(2)의 경사부(7)와 제2부싱(10)에 접촉되는 간격을 균일하게 유지시켜 주게 된다.At this time, the first bushing 6a on the inclined portion 7 side of the connecting pin 2 pushes the first bushing 6b on the other side of the second bushing 10 so that the swinging arm 3 swings. While being properly moved, the first bushings 6a and 6b of both sides maintain a uniform gap between the inclined portion 7 of the connecting pin 2 and the second bushing 10.

이상의 설명에서와 같이 본 고안은, 요동기구의 관절연결구에 부싱의 마모로 인한 진동과 소음이 발생하게 되면 간단히 너트를 조작해 줌으로서 마모량을 보상시켜 항상 균일한 접촉이 이루어지도록 하여 진동과 소음을 방지함은 물론 부품을 보호해 줄 수 있게되는 효과가 있다.As described above, the present invention, when vibration and noise caused by the wear of the bushing in the joint connector of the swinging mechanism simply compensates the amount of wear by simply operating the nut to make a uniform contact always makes vibration and noise In addition to preventing, there is an effect that can protect the parts.
