본 고안은 냉동기용 압축기의 피스톤과 커넥팅로드의 결합구조에 관한 것이다.The present invention relates to a coupling structure of the piston and the connecting rod of the compressor for a refrigerator.

종래에는 피스톤의 내부 중앙에 커넥팅로드의 하단에 결합된 볼이 자리하는 볼시이트를 형성하고 이 외주면에 복수개의 고정편을 형성하여 볼과 볼시이트 사이에 테프론등이 합성수지로 된 쿳션부재를 사이에 끼우고 고정편의 상부를 내측으로 절곡시켜 피스톤에 커넥팅로드를 결합하였던 바, 고정편을 적당한 힘을 가하도록 절곡시키는 작업이 매우 까다롭고 만약에 고정편의 절곡부위의 누르는 힘이 작을 때에는 커넥팅로드의 볼과 피스톤의 볼시이트 사이에 간극이 발생하여 소음의 원인이 되고, 반대로 고정편의 절곡부위의 누르는 힘이 클 때에는 볼과 볼시이트가 너무 압착되어 커넥팅로드와 피스톤의 움직임이 원활하지 못하여 압축기의 압력이 높아지는 폐단이 있었다.Conventionally, a ball seat in which a ball coupled to a lower end of a connecting rod is located at an inner center of a piston is formed, and a plurality of fixing pieces are formed on the outer circumferential surface thereof, and a cushion member made of synthetic resin between Teflon and ball seat is formed between the ball and the ball seat. When connecting the connecting rod to the piston by bending the upper part of the fixing piece to the inside, bending the fixing piece to apply a proper force is very difficult. A gap is generated between the piston and the ball seat of the piston, causing noise. On the contrary, when the pressing force of the bent portion of the fixed piece is large, the ball and the ball sheet are compressed too much, so that the connecting rod and the piston cannot move smoothly. There was a rising lung.

본 고안의 목적은 상기와 같은 문제점을 해결하기 위하여 볼시이트의 고정편과 커넥팅로드의 볼 사이에 탄성편을 가진 볼고정판을 안착시키고 고정편의 상부를 절곡시켜 피스톤에 커넥팅로드를 결합함으로써 고정편이 절곡되어 압착하는 힘에 관계없이 커넥팅로드와 피스톤을 균일한 상태로 결합할 수 있는 압축기의 피스톤과 커넥팅로드의 결합구조를 제공함에 있다.The purpose of the present invention is to solve the above problems by seating the ball fixing plate having an elastic piece between the ball of the fixing piece and the connecting rod of the ball seat and bending the upper part of the fixing piece by coupling the connecting rod to the piston bending the fixing piece It is to provide a coupling structure of the piston and the connecting rod of the compressor that can couple the connecting rod and the piston in a uniform state regardless of the pressing force.

이하 본 고안의 한 실시예를 첨부 도면에 따라 상세히 설명하기로 한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

피스톤(1)의 내저면 중앙부에 반구형의 볼시이트(2)가 형성되고 그 외주면 상잔에 복수개의 고정편(3)이 마련되어 상기 볼시이트(2)에 커넥팅로드(4)의 하단에 연결된 볼(5)을 결합시키는 것에 있어서, 제1도에서 도시한 바와같이 중앙 상부로 반구형의 원통부(6)를 형성하되 그 상부 중심부에 관통공(6')을 천공하고 상기 원통부(6)의 하단에서 연장된 바닥면(7)의 외주면에 복수개의 탄성편(8)을 입설하여서 볼고정구(9)를 볼(5)과 고정편(3) 사이에 개재시킨 것으로서, 상기 탄성편(8)은 피스톤의 볼시이트(2) 외주면에 형성된 고정편(3)과 대응하는 갯수만큼 형성함이 바람직하다.A hemispherical ball seat 2 is formed in the center of the inner bottom surface of the piston 1, and a plurality of fixing pieces 3 are provided on the upper surface of the outer peripheral surface thereof, and a ball connected to the lower end of the connecting rod 4 to the ball seat 2. 5) In the coupling, as shown in FIG. 1, a hemispherical cylindrical part 6 is formed in the upper part of the center, and the through hole 6 'is drilled in the upper center part thereof, and the lower end of the cylindrical part 6 is formed. The elastic piece 8 is interposed between the ball 5 and the stationary piece 3 by placing a plurality of elastic pieces 8 on the outer circumferential surface of the bottom surface 7 extending from. It is preferable to form the number corresponding to the fixed piece 3 formed in the outer peripheral surface of the ball seat 2 of a piston.

이와같이 구성된 본 고안은 제2도에서 도시한 바와같이 피스톤(1)의 볼시이트(2)에 커넥팅로드(4)의 볼(5)을 위치시키고 그 상부에 볼고정구(9)를 안착시키면 볼(5)의 상부는 볼고정판의 중앙반구형의 원통부(6)의 내면에 끼워지고 관통공(6')위로 커넥팅로드(4)가 돌출되게 되며 볼고정구(9)의 각 탄성편(8)이 볼시이트의 고정편(3) 내주면에 각각 면접되게 된다.The present invention configured as described above has a ball (5) of the connecting rod (4) on the ball seat (2) of the piston (1) as shown in FIG. The upper part of 5) is fitted to the inner surface of the central hemispherical cylindrical part 6 of the ball fixing plate, and the connecting rod 4 protrudes over the through hole 6 ', and each elastic piece 8 of the ball fixing tool 9 is The inner surfaces of the fixing piece 3 of the ball seat are interviewed.

이와같은 상태에서 각 고정편(3)의 상부를 내측으로 절곡시켜 피스톤(1)에 커넥팅로드(4)를 결합시키는 것으로, 이때 고정편(3)이 볼고정구의 반구형의 원통부(6)를 직접 누르지 않고 탄성편(8)을 눌러주기 때문에 고정편(3)의 절곡되는 양이 약간 차이가 있어도 탄성편(8)의 탄력에 의해 볼시이트(2)에 결합된 볼(5)에 균일한 힘이 가해짐으로 소음을 방지할 수 있고 또한 압축기의 효율을 높일 수 있는 특징을 지닌 것이다.In such a state, the upper part of each fixing piece 3 is bent inward to couple the connecting rod 4 to the piston 1, where the fixing piece 3 opens the hemispherical cylindrical part 6 of the ball fixture. Since the elastic piece 8 is pressed without pressing directly, even if the bending amount of the fixing piece 3 is slightly different, the elastic piece 8 is uniform to the ball 5 coupled to the ball seat 2 by the elasticity of the elastic piece 8. The force is applied to prevent noise and increase the efficiency of the compressor.
