본 고안은 브라인드 리벳트의 구조를 개량시킨 것으로 보다 구체적인 특징은 브라인드 리벳트의 체결관에선 변형부를 만들고 그 표면에 로렛트 홈을 형성함으로서 접속 봉체의 가압부가 체결관을 가압하면 로렛트홈에 의해 선변형부가 먼저 수축되면서 옆으로 균일하게 벌어져서 연겨란을 긴밀하게 밀착할 수 있게 한 것이다.The present invention improves the structure of the blind rivet, and more specifically, the deformation part is formed in the fastening tube of the blind rivet, and a slot groove is formed on the surface thereof. The deformed portion is first contracted to spread evenly to the side to allow close contact with the soft egg.

종래의 브라인드 리벳트는 체결관이 길게 되어 표면으로 횡 안내홈을 형성하였기 때문에 가압부를 가압하여 체결관체가 균일하게 수축되지 않고 불규칙적으로 수축되면서 표면이 벌어지므로 밀착부가 가즈런하지 않고 연결관의 접속이음부가 헐거워지는 등의 결점이 있었다.In the conventional blind rivet, since the fastening tube is extended to form a lateral guide groove on the surface, the pressing part is pressurized so that the fastening tube body is not contracted uniformly but is contracted irregularly so that the surface is opened. There was a flaw such as loosening.

본 고안은 이러한 결점을 해소하기 위하여 안출한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve these drawbacks and will be described in detail by the accompanying drawings as follows.

브라인드 리벳트(1)의 접속봉체(6) 외면에 끼워져서 결착편(2)과 연결되는 체결관(3)의 표면에 선변형부(4)를 만들어 그 표면에 로렛트홈(4a)을 형성시키고 로렛트 부분의 외면에 수개의 장공(4b)을 형성할 수 있게 한 구조이다.A linear deformation portion 4 is formed on the surface of the fastening pipe 3 which is fitted to the outer surface of the connecting rod 6 of the blind rivet 1 and is connected to the binding piece 2, thereby forming a lottery groove 4a on the surface thereof. It is the structure which made it possible to form several long holes 4b in the outer surface of a lottery part.

이와 같이 구성된 본 고안은 접속이음할 연결판(7)(7′)의 접속구멍(7a)에 브라인드 리벳트(1)의 체결관(3)을 끼워 결착편(2)의 접속구멍 표면에 밀착되게한 상태에서 접속봉(6)으로 가압부(5)를 가압하면 가압부가 체결관(3)을 가압하는 힘으로 선변형부(4)의 중앙부가 먼저 수축되어 외측면으로 벌어지면서 연결판(7)(7′)을 밀착하게 되는데 선변형부(4)의 표면에는 로렛트홈(4a)이 형성되어 있어서 로렛트홈이 옆으로 균일하게 확장되면서 벌어지게 되어 긴밀한 밀착을 할 수 있게 되고 균등한 형상으로 벌어지므로 연결판(7)(7′)을 견고하게 접속이음하게 되며 로렛트홈(4a)에 장공(4b)을 형성하면 선변형부(4)가 쉽게 확장될 수 있는 이점도 얻게 되는 것이다.According to the present invention configured as described above, the fastening pipe 3 of the blind rivet 1 is inserted into the connection hole 7a of the connection plate 7 (7 ') to be connected to the contact hole surface of the binding piece 2. When pressing the pressing portion 5 with the connecting rod (6) in the state to be the state that the pressing portion presses the fastening tube (3) by the force of the center portion of the linear deformation portion 4 is first contracted and opened to the outer side connecting plate (7) 7 'is in close contact with the surface of the linear deformation portion 4 is formed with a slot groove (4a) so that the slot groove is extended evenly to the side to be in close contact and can be made in an even shape Therefore, the connection plate (7) (7 ') is firmly connected to the connection, and forming the long hole (4b) in the slot groove (4a) is also the advantage that the line deformation portion 4 can be easily expanded.
