첨부도면 도 3은 본 고안에 따른 자동차의 촉매 컨버터 취부구조의 실시예를 도시하는 것으로서, 이에 따른 자동차의 촉매 컨버터 취부구조는 각 모서리부에 연결구멍(14a)이 형성된 가스켓(14)을 사이에 두고 촉매 컨버터(10)와 배기 파이프(12) 일측단부 연결단(16)(18) 각 모서리부에 천공된 관통공(16a)(18a)을 통하여 볼트(20)와 너트(22)로서 조립하는 자동차의 촉매 컨버터와 배기 파이프와의 취부구조에 있어서, 상기 촉매 컨버터(18)의 연결단(18a) 각 모서리부에 나사산이 형성된 볼트구멍(18b)을 각각 형성하고, 상기 볼트구멍(18b)에 상기 볼트(20)를 체결함에 의하여 상기 배기 파이프(12)와 가스켓(14), 촉매 컨버터(10)가 조립될 수 있도록 구성하여 된 것이다.3 is a view illustrating an embodiment of a catalytic converter mounting structure of a vehicle according to the present invention, and thus, a catalytic converter mounting structure of a vehicle includes a gasket 14 having a connection hole 14a formed at each corner thereof. Assembled as bolts 20 and nuts 22 through through holes 16a and 18a perforated at the corners of the catalytic converter 10 and the exhaust pipe 12 at one end of the connecting end 16 and 18, respectively. In the mounting structure of the catalytic converter and the exhaust pipe of an automobile, a threaded bolt hole 18b is formed in each corner of the connecting end 18a of the catalytic converter 18, and the bolt hole 18b is formed in each. By fastening the bolt 20, the exhaust pipe 12, the gasket 14, and the catalytic converter 10 are configured to be assembled.
도면 중 미설명부호 24는 머플러이다.In the figure, reference numeral 24 is a muffler.
상기와 같이 구성된 본 고안의 일실시예에 의한 작용을 설명한다.It describes the operation by one embodiment of the present invention configured as described above.
도 3에 도시된 바와 같이, 배기 파이프(12)와 촉매 컨버터(10)를 조립하고자 할 때, 상기 배기 파이프(12)의 일측 연결단(16) 모서리부에 형성된 관통공(16a)과, 가스켓(14)의 연결구멍(14a), 그리고 상기 촉매 컨버터(10)의 일측 연결단(18) 모서리부에 형성된 볼트구멍(18b)을 각각 맞춘 후, 소정 크기를 갖는 상기 볼트(20)를 삽입하여 상기 촉매 컨버터(10)의 볼트구멍(18b) 내부의 나사산 형성부에 취부하여 조립시키면 되므로 종래와 비교하여 너트(22)의 사용이 불필요하게 됨에 따라 작업이 수월해질 수 있게 된다.As shown in FIG. 3, when the exhaust pipe 12 and the catalytic converter 10 are to be assembled, a through hole 16a formed at a corner of one end 16 of the exhaust pipe 12 and a gasket. After fitting the connection holes 14a of the 14 and the bolt holes 18b formed at the corners of the one end 18 of the catalytic converter 10, the bolts 20 having a predetermined size are inserted. Since it is only necessary to attach and assemble the thread forming portion inside the bolt hole 18b of the catalytic converter 10, the use of the nut 22 becomes unnecessary as compared with the prior art, thereby facilitating the work.
이상에서와 같이, 본 고안에 따른 자동차의 촉매 컨버터 취부구조에 의하면 볼트를 상기 촉매 컨버터의 볼트구멍에 취부하여 배기 파이프와 촉매 컨버터의 조립이 간편하게 이루어짐에 의하여 작업이 수월해지고, 메인 아워가 절감되며 작업성이 향상됨은 물론 상기 너트의 미사용으로 인한 원가 절감의 부수적인 효과를 얻을 수 있게 된다.As described above, according to the catalytic converter mounting structure of the automobile according to the present invention, the bolt is mounted in the bolt hole of the catalytic converter to facilitate the work by simplifying the assembly of the exhaust pipe and the catalytic converter, and the main hour is reduced. The workability is improved as well as the side effect of cost reduction due to the non-use of the nut.
