본고안은 나사체결시 급속 체결 및 해체할 수 있는 원터치식 너트 조립체에 관한 것이다.This article relates to a one-touch nut assembly that can be fastened and disassembled when screwed in.
종래 일반적인 나사 체결시에는 제5도와 같이 피체결체(W)에 볼트(B)를 관통시키고 너트(N)를 수회 내지 수십회 돌려서 체결하며, 해체시에도 수회내지 수십회 돌려야 했으므로 나사 체결 및 해체시간이 대폭 지연되는 폐단이 있었다.Conventionally, when fastening the screw, as shown in Fig. 5, the bolt (B) is passed through the fastened body (W) and the nut (N) is fastened by turning several times to several tens of times. There was a significant delay.
따라서 본 고안은 이러한 종래의 폐단을 해소하고 체결할 볼트에 거의 체결 위치까지 그대로 밀어 넣은 상태에서 1회 이하로 회전하는 것에 의해 체결할 수 있으며 해제할 경우에도 체결력만 해체시킨 상태에서 그대로 빼어 낼수 있도록 한 원터치식 너트 조립체를 제공하려는 것이다.Therefore, the present invention eliminates these conventional closed ends and can be tightened by rotating it less than once in a state in which it is pushed to the fastening position almost as fast as it is, and even when released, it can be pulled out as it is in the disassembled state. It is to provide a one-touch nut assembly.
제1도 내지 제4도에 있어서, (1)은 피체결체(W)를 중간에 두고 볼트(B)에 체결되는 본 고안의 원터치식 너트조립체이다.In Figures 1 to 4, (1) is a one-touch nut assembly of the present invention that is fastened to the bolt (B) with the fastening body (W) in the middle.
너트 조립체(1)는, 각각 볼트(B)에 대해 법선 방향으로 계탈되는 나사부(3)와 캠핀(4)이 형성된 다수(도면에서는 3개)의 선형 분할 너트편(2)을, 선단 외주부에는 나사부(6)가 형성되고 중간부에는 상기 캠핀(4)이 출몰가능하게 관통되는 핀공(7)이 원주방향 등 간격으로 천설된 원통형 슬리브(5)내에 유삽하여 각각 한쌍의 인장 스프링(8)으로 연결하며, 상기 슬리브(5)의 나사부(6)에는 링너트(9)를 나합하고, 후단부에는 너트편 이탈 방지캡(10)을 핀(11)으로 고정하며, 링너트(9)와 이탈방지캡(10) 사이에는, 내주면에 다수(도면에는 3개)의 경사 캠부(13)와 원호부(14)가 교효로 형성된 조절링(12)을 유감한 것이다.The nut assembly 1 includes a plurality of linear split nut pieces 2 (three in the drawing) formed with a screw part 3 and a cam pin 4 which are engraved in the normal direction with respect to the bolt B, respectively, on the tip outer peripheral part. A threaded portion 6 is formed and a pin hole 7 through which the cam pin 4 is penetrated so as to penetrate in the middle portion is inserted into the cylindrical sleeve 5 which is installed at circumferentially equal intervals, respectively, as a pair of tension springs 8. The ring nut 9 is screwed into the threaded portion 6 of the sleeve 5, and the nut piece separation preventing cap 10 is fixed to the pin 11 by the pin 11 at the rear end thereof, and the ring nut 9 is separated from the ring nut 9. Between the prevention caps 10, it is regrettable that the inclined cam portion 13 and the circular arc portion 14 are formed alternately on the inner circumferential surface of the adjustment ring 12.
상기 이탈방지캡(10)의 외주면에는 너트편(2)의 볼트(B)에 대한 계합 및 해탈 상태 표지(15)(16)가 표시되어 있으며, 조절링(12)의 외주면에는 상기 표지(15)(16)을 선택적으로 지시하는 지시선(17)이 표시되어 있다.On the outer circumferential surface of the release preventing cap 10, the engagement and disengagement state indicators 15 and 16 for the bolt B of the nut piece 2 are indicated, and on the outer circumferential surface of the adjustment ring 12, the mark 15 A leader line 17 that selectively indicates) 16 is indicated.
상기 표지(15)(16)는 편의상 "ON", "OFF"로 표시한다.The markers 15 and 16 are labeled "ON" and "OFF" for convenience.
또한 상기 너트편(2)과 슬리브(5)는, 캠핀(4)이 핀공(7)이 관통되어 있으므로 나사체결시, 서로 축방향으로 밀리는 일은 없으나, 체결력이 클 경우 캠핀(4)이 휘어지거나 절단될 염려가 있는므로, 슬리브(5)의 내주면과 너트편(2)의 선단 외주면에는 각각 걸림 환턱(18)과 걸림턱(19)을 형성하여 나사체결시 슬리브(5)와 너트편(2)이 축방향으로 밀리는 것을 방지토록 하는 것이 보다 효과적이다.In addition, the nut piece 2 and the sleeve 5 are not pushed to each other in the axial direction at the time of screwing because the cam pin 4 penetrates the pin hole 7, but if the tightening force is large, the cam pin 4 is bent or Since there is a risk of cutting, the inner peripheral surface of the sleeve 5 and the outer peripheral surface of the distal end of the nut piece 2 are respectively formed with a locking annulus 18 and a locking jaw 19, respectively, when the sleeve 5 and the nut piece 2 are screwed. It is more effective to prevent) from being pushed in the axial direction.
미설명 부호(20)(21)은 스프링(8)을 고정키 위한 고정공 및 고정홈이며, (22)는 조절링(12)의 외주면에 각설된 너얼링부이다.Reference numeral 20, 21 is a fixing hole and a fixing groove for fixing the spring (8), 22 is a knurled portion squared on the outer circumferential surface of the adjustment ring (12).
이하 본 고안의 작동을 설명한다.Hereinafter will be described the operation of the present invention.
본 고안의 너트 조립체(1)를 볼트(B)에 체결함에 있어서는, 상기 조절링(12)를 돌려서 그 지지선(17)이 OFF 표지(16)에 일치되도록 하면, 제4도의 쇄선표시와 같이 너트편(2)의 캠핀(4)의 선단은 조절링(12)의 원호부(14)에 위치하게 되므로 캠핀(4)에 대한 경사캠부(13)의 중심방향 압압력이 해치되어 각 너트편(2)은 스프링(8)에 의하여 확개되면서 그 나사부(3)가 볼트(B)로부터 해탈된다.In fastening the nut assembly 1 of the present invention to the bolt B, by turning the adjusting ring 12 so that the support line 17 coincides with the OFF mark 16, the nut as shown in the dashed line in FIG. Since the tip of the cam pin 4 of the piece 2 is positioned at the arc portion 14 of the adjusting ring 12, the pressure in the center direction of the inclined cam portion 13 against the cam pin 4 is hatched, and thus each nut piece ( 2) is expanded by the spring 8, the threaded portion 3 is released from the bolt (B).
이 상태에서 너트조립체(1)는 볼트(B)에 대해 축방향으로 자유롭게 이동 가능하게 되므로 볼트(B)에 너트 조립체(1)를 체결직전의 위치까지 밀어 넣는다.In this state, since the nut assembly 1 is free to move in the axial direction with respect to the bolt B, the nut assembly 1 is pushed into the bolt B to the position just before fastening.
다음 조절링(12)을 그 지지선(17)이 ON 표지(15)에 일치하도록 돌리면 캠편(4)의 단부는 캠부(13)에 의해 중심방향으로 압압되며, 너트편(2)의 나사부(3)가 볼트(B)에 치합된다.Next, when the support ring 17 is turned so that the support line 17 coincides with the ON mark 15, the end of the cam piece 4 is pressed in the center direction by the cam part 13, and the screw part 3 of the nut piece 2 ) Is fitted to the bolt (B).
이 상태에서 작업자가 스패너 등에 의해 링너트(9)를 슬리브(5)의 나사부(6)에 대하여 돌려서 피체결체(A)에 밀착시키면되는 것이다.In this state, the operator may turn the ring nut 9 against the threaded portion 6 of the sleeve 5 by using a spanner or the like to bring it into close contact with the object to be fastened.
이때 링너트(9)는 최종 체결력을 가하는데 필요한 0.5-1회전만 돌리면 된다.At this time, the ring nut 9 only needs to turn 0.5-1 rotation necessary to apply the final tightening force.
이와같이 체결된 너트 조립체(1)를 볼트(B)로부터 해체할 경우에는, 상기 체결 과정과 역순으로 하면 된다.When disassembling the nut assembly 1 fastened in this way from the bolt B, it is good to reverse it to the said fastening process.
또한 상술한 체결 상태에서는 슬리브(5)와 너트편(2)은 캠핀(4)와 핀공(7)에 의해서 서로 축방향으로 밀리지 않을뿐 아니라 걸림단턱(18)과 걸림턱(19)에 의해서도 축방향 밀림이 방지되므로 너트 조립체(1)는 볼트(B)에 대해 견고하게 체결되는 것이다.In addition, in the above-mentioned fastening state, the sleeve 5 and the nut piece 2 are not pushed to each other by the cam pin 4 and the pin hole 7 in the axial direction, and the shaft by the locking step 18 and the locking step 19 are also prevented. The nut assembly 1 is firmly fastened to the bolt B since the directional push is prevented.
이상과 같이 본 고안에 의하면 나사 체결 및 해체함에 있어서 종래와 같이 수회내지 수십회 돌리지 않고 0.5-1회 정도 돌리는 것만으로써 체결 및 해체할 수 있으므로 그 작업이 신속하게 되는 효과가 있다.As described above, according to the present invention, since the screw can be fastened and dismantled by turning about 0.5-1 times instead of turning several times or tens of times as in the prior art, the work can be quickly performed.
