본 고안은 양쪽의 체결물을 압착하여 리벳팅하는 리벳트를 구성함에 있어서 벌림요입홈을 설한 지지축을 할개시켜 형성한 하부 리벳트와 압착되는 상부 리뱃트에 강압돌출봉과 물림 지지동체를 형성하여 구성한 리벳트에 관한 것으로 상하부 리벳트를 압착함에 따라서 상부 리벳트의 강압 돌출봉에 의하여 벌려지는 하부 리벳트의 할개된 지지축을 상부 리벳트의 물림 지지동체에 의하여 협착되게 하여 상하 리벳트의 압착상태를 보다 견고하게 유지할 수 있으며. 특히 내부에서 작용하는 할개지지축의 벌림력을 외부에서 작용하는 물립지지동제의 협착력으로 압지하고 있으므로, 재질에 따라 외부 온도변화에 의하여 다소 신축성을 가진 리벳트인 경우에는 압착상태가 불량하여지는 일이 없이 항상 견고한 상태를 유지할 수 있게함에 주안점을 둔 것이다.The present invention is formed by forming a push-out bar and a bite support body in the upper rivet and the lower rivet formed by opening the support shaft with the opening recess groove in the riveting by crimping the fasteners on both sides. As the rivet is squeezed, the upper and lower rivets are squeezed by the split support shafts of the lower rivets, which are opened by the pressure-protruding rods of the upper rivets, by the bite supporting body of the upper rivets. To be more robust. In particular, since the gaping force of the split shaft support shaft acting inside is clamped by the clamping force of the granular support mechanism acting on the outside, the crimping state may be poor in the case of rivets having a somewhat elasticity due to external temperature change depending on the material. The main focus is on being able to remain solid at all times.
종래의 상부 리벳트에 요입홈을 형성시킨 지지봉의 요입홈에 하부 리벳트에 돌출시킨 돌출축이 끼워 물림되도록 구성하거나 돌출축의 하방둘레에 테이퍼형 요입홈을 요설하여 지지봉이 끼워 물림되도록 하였으나, 이는 하부 리벳트의 돌출축이 상부 리벳트에 형성시킨 지지봉의 효임홈에 강압되어 지지봉이 강제로 팽출되면서 끼워물림되거나 또는 상부 리벳트의 지지봉이 하부 리벳트에 요설한 테이퍼형 요입홈에 끼워 물림되어 지지되는 정도이므로 압착 작업은 용이하나 돌출축이 강압되어 지지봉의 파괴현상으로 불량 또는 견고성이 저하되게나 사용중에 외부의 인장력에 의한 압착력이 미약하며, 특히 리벳트가 외부 온도에 따른 신축성의 재질인 경우에는 압착력이 더욱 미약하여지는 결점이 있었다.In the conventional upper rivets, the support rod is formed in the recessed groove of the support rod is formed so that the protruding shaft protruding from the lower rivet is inserted or the tapered recessed groove in the lower periphery of the protruding shaft to the bite, but this The protruding shaft of the lower rivet is pushed by the filial groove of the support rod formed in the upper rivet, and the support rod is pushed into force by swelling, or the support rod of the upper rivet is inserted into the tapered recess groove recessed in the lower rivet. As it is supported, the crimping work is easy, but the protruding shaft is squeezed so that the failure of the supporting rods causes the failure or the rigidity to be degraded, but the crimping force due to external tension is weak during use. In the case, there was a defect that the compressive force was weaker.
본 고안은 종래의 결점을 적게하기 위하여 고안된 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to reduce the drawbacks of the prior art and will be described in detail by the accompanying drawings as follows.
상하부 리벳트(1)(2)에 형성한 곡면 두부(1a)(2a)의 후면으로 절단 평면부(3)(4)를 형성시킨 공지의 것에 있어서 하부 리벳트(2)의 절단 평면부(4)에 벌림요입구(5)와 연동시켜 할개부(6)를 형성한 할개 지지축(7)을 돌설하며, 상부 리벳트(1)의 절단 평면부(3)에는 벌림 요입구(5)의 내경(t)보다 약간의 둘레경(tb)만큼 큰외경(ta)을 가진 강압 돌출봉(8)을 돌설하되, 강압돌출봉(8)의 외주로 끼움 요입구(9)를 형성하는 물림 지지동체(10)를 돌설하여서 된 것이다.Cutting plane part of lower rivet 2 in the well-known thing which formed cutting plane part 3, 4 in the back surface of the curved head part 1a, 2a formed in the upper and lower rivets 1, 2 ( 4) the bulge support shaft 7 which interlocks with the cavitation inlet 5 and forms the lap part 6 and protrudes, and the piercing inlet 5 on the cutting plane 3 of the upper rivet 1 some circumference than the inner diameter (t) If (t b) by a large outer diameter (t a), but dolseol the step-down protruding rods 8 with, yaw-fit to the outer periphery of the step-down protruding rods (8) forming the inlet (9) Is made by protruding the bite support body (10).
이와같은 본 고안은 상부 리벳트(1)의 끼움 요입구(9)내에 하부 리셋트(2)의 할개 지지축(7)을 끼워 맞춘상태에서 상부 리벳트(1)를 가압하게 되면 강압돌출봉(8)이 벌림 요입구(5)내로 끼워 들어가게 되는데 이때 벌림요입구(5)의 내경(t)보다 강압돌출봉(8)의 외경(ta)이 약간의 둘레경(tb)만큼 이므로 강압 돌출봉(8)은 벌림 요입구(8)내에 강제로 끼워 들어가면서 도면 제4도에 표시한 화살표 방향과 같이 할개부(6)에 의하여 할개지지축(7)이 외부로 강력한 벌림력을 작용함과 동시에 물림 지지동체(10)가 할개 지지축(7)의 외부에서 강력한 협착력을 작용하면서 상부의 리벳트(1)(2)는 강력하게 압착되는 것이다.The present invention as described above, when pressing the upper rivet (1) in the state of fitting the opening support shaft (7) of the lower reset (2) in the fitting inlet (9) of the upper rivet (1) (8) is inserted into the opening inlet (5), since the outer diameter (t a ) of the pressure-protruding bar (8) is a slight circumference (t b ) than the inner diameter (t) of the opening inlet (5). The stepping bar 8 is forcibly inserted into the opening inlet 8, and the opening support shaft 7 exerts a strong opening force to the outside by the opening part 6 in the direction of the arrow shown in FIG. At the same time, while the bite support body 10 exerts a strong clamping force on the outside of the tear support shaft 7, the upper rivets 1 and 2 are strongly compressed.
이와같이 된 본 고안은 상부 리벳트의 물림 지지동체내에 끼움 요입구를 형성하는 강압 돌출봉에 의하여 하부 리벳트의 할개 지지축이 강력한 벌림력을 작용함에 대하여 상부 리벳트의 물림 지지동체가 강력한 협착력을 작용하고 있으므로 상하부 리벳트는 항상 강력안 압착력을 유지할 수 있는 것이며, 상하부 리벳트를 형성함에 있어서 하부 리벳트를 상부 리벳트보다 다소 신축성이 있는 재질을 사용하게 되면 상하 리벳트의 가압작업을 보다 용이하게 함은 물론 할개 지지축의 벌림력과 물림 지지동체의 협착력이 강력하제 작용하고 있으므로 사용중에 외부 온도의 변화에도 압착력이 불량하여 지는 일이 없이 항상 견고한 상태를 유지할 수 있는 이점이 있는 것이다.The present invention has a strong clamping force against the rivet support body of the upper rivets due to the strong opening force of the opening support shaft of the lower rivets by a push-out protrusion that forms a recess in the upper support rivet. The upper and lower rivets can always maintain a strong compressive force, and when forming the upper and lower rivets, it is easier to press the upper and lower rivets when the lower rivet is made of a material that is somewhat elastic than the upper rivet. Of course, the opening force of the opening of the opening of the shaft and the clamping force of the bite support body act as a strong laxative, so that there is an advantage that the compression force can be maintained at all times without changing the external temperature during use.
