본 고안은 자동차용 촉매장치의 봉인구에 관한 것이다 .The present invention relates to the sealing port of the catalyst device for automobiles.
종래의 자동차용 촉매장치의 봉인구는 제 3도 내지 제 5도에 도시한 바와 같이 촉매장치 케이싱(1)과 배기관(2)의 플렌지(3)(3')에 뚫은 체결공(4)(4')에 체결볼트(5)를 너트(6)로 체결하여 플렌지(3)(3')를 고정하고, 1개이상의 체결볼트(5)에 뚫은 관통구멍(7)에 봉인와이어(8)를 끼운 후 그 양단에 봉인납(9)(9')을 고정하여 봉인하였으므로 봉인납(9)(9')이 2개가 필요하고 봉인와이어(8)의 절단등 마무리 작업을 하여야 하므로 원가상승 요인이 될 뿐 아니라 생산송도 문제가 있고, 자동차의 주행중에 봉인와이어가 절단되는 현상이 생길때 운전자가 고의로 촉매를 파손시키는 경우가 있어서 소기의 배기가스 정화를 할 수 없게 되어 대기오염을 유발시키는 문제점이 있었다.As shown in FIGS. 3 to 5, the sealing holes of the conventional catalyst for automobiles are fastening holes 4 and 4 drilled in the flanges 3 and 3 'of the catalyst device casing 1 and the exhaust pipe 2. Fasten the fastening bolt (5) with the nut (6) to fix the flange (3) (3 '), and the sealing wire (8) in the through hole (7) drilled in one or more fastening bolt (5) Since the sealing lead (9) (9 ') is fixed to both ends after insertion, the sealing lead (9) (9') needs two and the finishing work such as cutting of the sealing wire (8) requires a cost increase factor. In addition, there is a problem in producing the air, and the driver may intentionally break the catalyst when the sealing wire is cut while the vehicle is running. .
본 고안은 상기한 문제점을 해결하여 작업성과 내구성을 향상시키고 봉인납이 파손되는 것을 방지토록 한 자동차의 촉매장치 봉인구를 제공하는 것을 목적으로 한다.The object of the present invention is to provide a catalyst device sealing port for a vehicle to solve the above problems to improve workability and durability and to prevent the sealing lead from being broken.
본 고안은 상기한 목적을 달성하기 위하여 촉매장치 케이싱과 배기관의 플렌지를 체결하는 1개이상의 체결볼트의 너트체결부에 축방향의 홈과 상기 축방향의 홈에 연통되는 원주방향의 구멍을 형성하여 봉인납을 상기 홈과 구멍에 매몰시킴과 동시에 체결볼트에 돌출되게 형성하여서 된 것이다.The present invention is to form a circumferential hole in communication with the axial groove and the axial groove in the nut coupling portion of one or more fastening bolts for fastening the flange of the catalyst casing and the exhaust pipe to achieve the above object The sealing lead is buried in the groove and the hole and formed to protrude to the fastening bolt.
이하 실시예도면에 의하여 설명한다.A description with reference to the following drawings.
본 고안은 제 1도 및 제 2도(a)에 도시한 바와 같이 촉매장치 케이싱(1)과 배기관(2)의 플렌지(3)(3')에 뚫은 체결공(4)(4')에 체결볼트(5)를 너트(6)로 체결하여 플렌지(3)(3')를 고정한 것에 있어서 1개이상의 체결볼트(5)의 너트체결부(11)에 축방향의 홈(12)과 상기 축방향의 홈(12)에 연통되는 다수의 원주방향의 구멍(13)을 형성하여 봉인납(14)을 상기 홈(12)과 구멍(13)에 매몰시킴과 동시에 체결볼트(5)에 돌출되게 형성하여서 된 것이다 .The present invention, as shown in Figures 1 and 2 (a) to the fastening holes (4) (4 ') drilled in the flange (3) (3') of the catalyst casing (1) and the exhaust pipe (2) The fastening bolt 5 is fastened with the nut 6 to fix the flanges 3, 3 ′ in the nut fastening portion 11 of the at least one fastening bolt 5. A plurality of circumferential holes 13 communicating with the axial grooves 12 are formed to bury the sealing lead 14 in the grooves 12 and the holes 13 and simultaneously protrude into the fastening bolts 5. It was formed to be.
상기한 봉인납(14)은 용융상태의 납을 상기한 홈(12)과 구멍(13)에 부어서 응고시키는 등의 방법으로 제조한다.The sealed lead 14 is manufactured by pouring molten lead into the grooves 12 and the holes 13 to solidify.
이상과 같은 본 고안은 촉매장치 케이상(1)과 배기관(2)에 형성된 플렌지(3)(3')에 뚫은 체결공(4)(4')에 체결볼트(5)를 끼운다음 너트(6)를 체결하여 촉매장치 케이싱(1)과 배기관(2)을 연결 고정한 다음 체결볼트(5)에 돌출된 봉인납(14)을 봉인치구를 사용하여 제 2도(b)에 도시한 바와 같이 봉인납(14)의 직경이 체결볼트(5)의 외경보다 크게 가압하면 봉인작업이 완료되는 것이다.The present invention as described above inserts the fastening bolt (5) in the fastening holes (4) (4 ') drilled in the flange (3) (3') formed on the catalyst device k phase (1) and the exhaust pipe (2) and then the nut ( 6) by fastening the catalyst casing (1) and the exhaust pipe (2), and then the sealing lead 14 protruding from the fastening bolt (5) using a rod inch hole as shown in Figure 2 (b) If the diameter of the sealing lead 14 is larger than the outer diameter of the fastening bolt 5, the sealing is completed.
이상과 같이 본 고안은 1개이상의 체결볼트에 홈과 상기 홈에 연통되는 구멍을 형성하여 봉인납을 매몰시켰으므로 체결볼트와 봉인납이 일체화되어 견고하므로 내구성이 향상될 뿐 아니라 플렌지에 체결볼트를 제공후 봉인납의 돌출부분을 가압하여 체결볼트의 외경보다 크게 형성하므로서 작업성이 향상되어 원가절감에 기여하고, 너트를 분해하지 않고는 봉인의 위조가 불가능하여 소기의 배기가스 정화효율을 달성할 수 있는 효과 등이 있다.As described above, the present invention forms a groove in one or more fastening bolts and a hole communicating with the grooves, so that the sealing lead is buried, so that the fastening bolt and the sealing lead are integrated and solid, so that the durability is improved and the fastening bolts are mounted on the flange. After the provision, the projecting part of the sealing lead is pressurized to form larger than the outer diameter of the fastening bolt, thereby improving workability and contributing to cost reduction, and it is impossible to forge the seal without disassembling the nut to achieve the desired exhaust gas purification efficiency. There is such an effect.
