Description
본 발명은 자동차용 푸시너트에 관한 것으로서, 더욱더 상세하게는 조립 및 분해가 용이하고, 정비시 손상되지 않아 재 사용할 수 있도록 하는 자동차용 푸시너트에 관한 것이다.The present invention relates to a push nut for an automobile, and more specifically, to a push nut for an automobile that is easy to assemble and disassemble, and is not damaged during maintenance, allowing for reuse.
일반적으로 자동차용 푸시너트는 스크류등과 같은 체결품을 이용하여 부재와 부재 혹은 장착부품을 결합할 때 체결품과 부재 사이에 생기는 미세한 틈을 막아 방진 , 방음, 방수의 효과를 얻는 중간부품이다.In general, a push nut for an automobile is an intermediate part that provides dustproofing, soundproofing, and waterproofing effects by closing the minute gap that occurs between the fastener and the member when joining members or mounted parts using fasteners such as screws.
여기에서 종래 자동차용 푸시너트는 부재접촉면이 좌우 양측으로 돌출되어 형성되고, 중앙부에는 체결공이 관통되어 형성된 머리부와; 상기 머리부에 형성된 체결공과 중심과 내경이 동일한 체결공이 중앙부에 관통되어 형성되고, 좌우 양측부에는 걸림턱이 돌출되게 형성된 바디부로 구성되어 있다. Here, the conventional push nut for automobiles has member contact surfaces protruding on both left and right sides, and has a head formed through a fastening hole in the central portion; It is composed of a body portion in which a fastening hole having the same center and inner diameter as the fastening hole formed in the head penetrates the central portion, and locking protrusions are formed on both left and right sides.
이러한 종래 자동차용 푸시너트는 걸림턱이 좌우 양측부에 돌출되어 형성된 바디부를 부재에 형성된 구멍에 밀어 넣으면, 상기 바디부의 하부에 형성된 머리부의 부재접촉면이 부재의 외측면에 밀착되고, 상기 부재접촉면이 부재의 외측면에 접촉되도록 구멍에 인입이 이루어진 바디부는 걸림턱에 의해 부재의 외부로 빠지지않게 고정되어지게 된다.In such a conventional push nut for automobiles, when the body part formed with the locking protrusion on both left and right sides is pushed into the hole formed in the member, the member contact surface of the head formed in the lower part of the body part is in close contact with the outer surface of the member, and the member contact surface is The body part that is inserted into the hole to contact the outer surface of the member is fixed to prevent it from falling out of the member by a locking protrusion.
그러나 이러한 종래 자동차용 푸시너트는 바디부의 좌우 양측에 걸림턱이 고정되게 돌출 형성되는 관계로, 상기 바디부를 부재에 형성된 구멍에 삽입시, 상기 걸림턱이 구멍의 내측벽면에 접촉되면서 변형되어지게 됨은 물론, 상기 걸림턱에 의해 구멍이 형성된 부재부위가 변형 및 파손이 발생하게 되는 문제점이 있었다.However, in this conventional push nut for automobiles, the locking protrusion is fixedly protruded on both left and right sides of the body, so when the body part is inserted into the hole formed in the member, the locking protrusion contacts the inner wall of the hole and is deformed. Of course, there was a problem in that the part of the member where the hole was formed by the locking protrusion was deformed and damaged.
한편, 종래에는 상기 바디부를 부재의 구멍에 삽입시켜 걸림턱에 의해 부재의 외부로 빠지지 않게 고정되는 관계로, 푸시너트를 부재로 부터 분리시켜 수리를 수행하지 못하게 되는 등의 문제점이 있었다. Meanwhile, in the related art, the body portion was inserted into the hole of the member and fixed by a locking protrusion to prevent it from falling out of the member, so there was a problem that repairs could not be performed by separating the push nut from the member.
본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 바디부가 부재의 구멍에 탄성변형이 이루어지면서 부재의 구멍을 통해 인입출이 이루어지도록 함과 동시에 상기 바디부가 스크류와 같은 체결품을 이용하여 부재와 부재 혹은 장착부품을 결합할 때, 과체결결로 인한 파손이 발생하지 않도록 하는 자동차용 푸시너트를 제공하는 데 있다.The purpose of the present invention is to solve the above-described conventional problems.
