이하, 첨부 도면을 참조하여 본 발명의 상세한 일 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

제1도와 제2도는 본 발며에 따른 자동차용 연료 필러 튜브 연결 구조를 도시한 분해 사시도와 조립 반단면도로서, 연료 필러 튜브(53)와 연료 탱크(51)의 파이프(50)가 삽입되어 고정됨과 아울러 이탈되지 않도록 하는 급속 결합 수단과, 상기한 결합시 연료 누출을 방지하기 위해 연료 필러 튜브(53)측에 형성된 시일 수단으로 구성되어 있다.1 and 2 are an exploded perspective view and an assembled half sectional view showing a fuel filler tube connection structure for automobiles according to the present invention, in which the fuel filler tube 53 and the pipe 50 of the fuel tank 51 are inserted and fixed. In addition, it is composed of a quick coupling means for preventing the separation and the sealing means formed on the fuel filler tube 53 side to prevent fuel leakage during the above-described coupling.

여기서, 상기한 급속 결합 수단은 상기한 연료 탱크(51)에 형성된 파이프(50)의 선단부에 형성되어 있는 걸림턱(1)과, 상기한 걸림턱(1)이 삽입된 후 외부로 이탈되지 않도록 고정 수단이 형성됨과 아울러 연료필러 튜브(53)가 결합되어 있는 하우징(2)과 리테이너(3)가 고정되도록 형성된 제한 수단으로 구성되어 있다.In this case, the quick coupling means is a locking jaw (1) formed in the front end of the pipe 50 formed in the fuel tank 51 and the locking jaw (1) is inserted so as not to be separated to the outside. The fixing means is formed, and the housing 2 and the retainer 3 to which the fuel filler tube 53 is coupled are configured.

상기한 고정수단은 리테이너(3)의 측벽에 형성된 구멍(4)과, 상기한 구멍(4)에 하단이 돌출되어 삽입된 파이프(50)의 걸림턱(1)을 제한함과 아울러 리테이너(3)의 상단에 일체로 형성되어 있는 탄성 돌기(5)로 구성되어 있다.The fixing means restricts the locking jaw 1 of the hole 4 formed in the side wall of the retainer 3, the pipe 50 inserted into the hole 4 by the lower end thereof, and the retainer 3. It consists of the elastic protrusions 5 integrally formed in the upper end of the).

또한, 상기한 제한 수단은 리테이너(3)의 외주에 형성된 삽입부(6)와, 상기한 삽입부(6)와 결합되도록 하우징(2)에 형성된 굽힘부(7)로 형성되어 있고, 시일 수단은 하우징(2)의 내측 일부분 즉, 파이프(50)의 선단이 위치되는 부분에 형성되어 이를 압착하는 시일재(8)로 구성되어 있다.Further, the limiting means is formed of an insertion portion 6 formed on the outer circumference of the retainer 3, and a bent portion 7 formed in the housing 2 so as to be engaged with the insertion portion 6, and the sealing means. Is formed in the inner part of the housing 2, that is, the seal member 8 which is formed in the part where the tip of the pipe 50 is located and crimps it.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 연료 필터 튜브(53)의 하우징(2)에 리테이너(3)가 결합되어 있는 상태에서 작업자가 연료 탱크(51)의 파이프(50)를 삽입하게 되면 상기한 파이프(50)의 걸림턱(1)이 리테이너(3)의 탄성 돌기(5)를 압박하면서 삽입된다.Referring to the operation and effect of the present invention as described above when the operator inserts the pipe 50 of the fuel tank 51 in the state that the retainer 3 is coupled to the housing 2 of the fuel filter tube 53 The locking jaw 1 of the pipe 50 is inserted while pressing the elastic projection 5 of the retainer 3.

즉, 걸림턱(1)이 탄성돌기(5)를 압박하면 탄성돌기(5)가 양측으로 벌어지게 되고, 일정 이상 벌어지게 되면 걸림턱(1)이 탄성 돌기(5)를 넘어서게 되며, 탄성 돌기(5)는 다시 내측으로 압축되면서 걸림턱(1)의 배면 즉, 도면에서 상면으로 지지하게 된다.That is, when the locking jaw 1 presses the elastic protrusion 5, the elastic protrusions 5 are opened to both sides, and when the locking jaw 1 is opened more than a predetermined time, the locking jaw 1 extends beyond the elastic protrusions 5 and the elastic protrusions. (5) is back to the inside of the latching jaw (1) while being compressed to the inside, that is to support the upper surface in the drawing.

탄송 돌기(5)가 걸림턱(1)의 배면을 지지하게 되면 파이프(50)가 외부의 힘에 의해 이탈되지 않게 되는 것이다.When the projecting projection 5 supports the back surface of the locking step 1, the pipe 50 is not separated by external force.

물론, 상기한 탄성돌기(5)는 리테이너(3)에 형성된 구멍(4)을 통해 유동 가능하게 된다.Of course, the elastic protrusion (5) is able to flow through the hole (4) formed in the retainer (3).

이때, 상기한 파이프(50)의 선단은 탄성 돌기(5)에 지지된 상태에서 하우징(2)에 삽입되는 바, 상기한 선단은 하우징(2)의 내면에 설치된 시일재(8)에 의해 압박되면서 그 사이를 밀폐시키게 된다.At this time, the tip of the pipe 50 is inserted into the housing 2 while being supported by the elastic protrusion 5, the tip is pressed by the sealing material 8 provided on the inner surface of the housing (2). It is sealed between them.

즉, 연료 필러 튜브(53)를 타고 유입되는 연료가 파이프(50)를 통해 연료 탱크(51)로 유입되지 않고 하우징(2)로 누출되는 것을 시일재(8)가 차단하게 되는 것이다.That is, the sealing material 8 blocks the fuel flowing in the fuel filler tube 53 from leaking into the housing 2 without entering the fuel tank 51 through the pipe 50.

상기한 바와 같이 연료 탱크(51)의 파이프(50)와 연료 필러 튜브(53)를 결합하여 사용하는 중 연료 필러 튜브(53)를 교체해야 하는 일이 발생되면 연료 필러 튜브(53)를 작업자가 잡아 당기게 된다.As described above, when the pipe 50 of the fuel tank 51 and the fuel filler tube 53 are combined and used, the fuel filler tube 53 needs to be replaced. Pulled.

물론, 소정 이상의 힘을 주어야 하는 바, 상기한 바와 같이 연료 필러 튜브(53)를 당기게 되면 리테이너(3)가 동시에 당겨지면서 하우징(2)의 굽힘부(7)와 결합된 삽입부(6)가 굽힘부(7)에서 이탈되면서 연료 필러튜브(53)가 분리된다.Of course, it is necessary to apply a predetermined force or more, as described above, when the fuel filler tube 53 is pulled, the retainer 3 is pulled at the same time while the insertion portion 6 coupled with the bent portion 7 of the housing 2 The fuel filler tube 53 is separated while being separated from the bent portion 7.

즉, 삽입부(6)와 결합된 하우징(2)의 굽힘부(7)가 약간 벌어지면서 리테이너(3)가 이탈되는 것이다.In other words, the bent portion 7 of the housing 2 coupled with the insertion portion 6 is slightly opened and the retainer 3 is separated.

여기서, 상기한 굽힘부(7)의 곡률을 매우 작게 함과 아울러 삽입부(6)에 삽입되는 양을 작게 하면 이탈시 하우징(2)이 손상되지 않게 된다.Here, if the curvature of the bent portion 7 is made very small and the amount of the inserted portion 6 is small, the housing 2 is not damaged during separation.

이상과 같이 본 발명은 자동차의 연료 필러 튜브를 이테이너와 걸림턱을 사용하여 간편하게 연료 탱크에 연결함으로써 연료 필러 결합 작업이 단순화되는 잇점이 있는 것이다.As described above, the present invention is advantageous in that the fuel filler coupling operation is simplified by simply connecting the fuel filler tube of the vehicle to the fuel tank using the retainer and the locking jaw.
