본 고안은 핀(pin)의 이탈 방지장치에 관한 것으로, 특히 핀의 이탈을 방지하면서도 특별한 공구의 사용 없이 핀의 탈착 작업을 용이하게 할 수 있도록 한 핀 이탈 방지 장치에 관한 것이다.The present invention relates to a pin release prevention device, and more particularly to a pin release prevention device that can prevent the removal of the pin and facilitate the removal of the pin without the use of a special tool.

일반적으로 핀은 고정물이 쉽게 빠지지 않도록 하는 기계 요소의 하나로 평행핀, 테이퍼핀 등 많은 종류가 있다.In general, there are many types of pins, such as parallel pins and tapered pins, as one of the mechanical elements to prevent the fixture from easily falling out.

그런데, 핀이 끼워진 고정물의 진동이 심할 경우에는 끼워 둔 핀이 빠짐으로써, 고정물의 고정이 쉽게 해제되는 수가 있어서 이를 방지하기 위한 각종 수단이 강구되고 있다.By the way, when the vibration of the fixture in which the pin is fitted is severe, the pin may be pulled out so that the fixing of the fixture can be easily released, and various means for preventing the fixation have been devised.

이러한 핀 이탈 방지 장치로는, 끼워진 핀을 다시 보울트로 고정하는 방법과 핀의 선단에 다른 핀을 삽입하거나 핀의 선단을 물러 고정시키는 수단등이 널리 이용되고 있다.As such a pin release prevention device, a method of fixing the pins pinned back to the bowl, a means of inserting another pin at the tip of the pin, or a step of holding the tip of the pin back is widely used.

제3도는 종래의 핀 이탈 방지 장치로서 분할 핀을 사용한 것을 도시한 것으로, 고정물(31)에 핀(32)을 삽입한 후 이 핀(32)이 반대쪽으로 빠지지 않도록 하는 핀 머리(33)가 형성되어 있고, 핀(32)의 선단에 작은 분할 핀(34)이 삽입되며, 또 이 분할 핀(34)이 빠지지 않도록 하는 스토퍼(35)가 형성된 구조로 되어 있다.FIG. 3 shows the use of the split pin as a conventional pin release preventing device. The pin head 33 is formed to prevent the pin 32 from falling out after inserting the pin 32 into the fixture 31. A small split pin 34 is inserted into the tip of the pin 32, and a stopper 35 is formed so that the split pin 34 does not come off.

그러나 이러한 종래의 핀 이탈 방지장치는 핀 이탈 방지의 효과는 크지만, 자주 핀을 뽑아야 하는 경우에는 상당히 번거롭고 불편하게 된다.However, the conventional pin release prevention device has a great effect of preventing pin release, but it is quite cumbersome and inconvenient when the pins are often to be removed.

즉, 핀을 고정하기 위해 보울트를 사용하는 경우 수시로 탈착하는 것이 번거롭고 어려우며, 또 공구를 사용해야 된다는 문제점이 있고, 분할 핀으로 핀을 고정하는 경우는 분할 핀을 끼우고 빼는 것이 힘들고 또 고정 수단으로 중요한 역할을 하는 분할 핀이 크기가 작음으로 인해 쉽게 분실된다는 문제점이 있었다.In other words, when the bolt is used to fix the pin, it is cumbersome and difficult to remove it from time to time, and there is a problem that a tool must be used.In the case of fixing the pin with the split pin, it is difficult to insert and remove the split pin and it is important as a fixing means. There was a problem that the split pin, which plays a role, is easily lost due to its small size.

이에 본 고안은 상기한 바와 같은 제문제점을 해소시키기 위해 안출된 것으로, 핀의 이탈을 방지함과 아울러 별도의 공구 없이 핀의 탈착을 용이하게 할 수 있게 한 핀 이탈 방지장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve the problems described above, and to prevent pin detachment as well as to provide a pin departure prevention device that can facilitate the removal of the pin without a separate tool. have.

상기한 바의 목적을 달성하기 위한 본 고안은, 핀 머리의 외주면 둘레에 홈이 형성되어 있으며, 핀이 끼워지는 고정물 본체에는 상기 핀 머리의 홈에 결착되어 핀이 빠지지 않도록 눌러주는 핀 이탈 방지장치가 설치된 구조로 되어 있다.The present invention for achieving the object of the bar is, the groove is formed around the outer peripheral surface of the pin head, the pin body is fixed to the pin body is fixed to the groove of the pin head pin pin is inserted to prevent the pin from falling out Has a structure installed.

이와 같이 구성된 본 고안의 핀 이탈 방지 장치는 고정물 본체에 두개의 지지 브라케트가 고정되고 그 사이에 상기 핀 머리의 홈에 결착되는 고정구가 축회전할 수 있게 설치 되어 있다.The pin detachment prevention device of the present invention configured as described above is provided so that two support brackets are fixed to the fixture body, and a fixture fastened to the groove of the pin head therebetween is axially rotated.

따라서, 핀을 끼울 때나 뽑을 때에는 상기 고정구를 세워서 핀 머리에 형성되어 있는 홈에 걸리지 않도록 하며, 핀을 끼운 다음 고정구를 눕혀서 고정구가 핀 머리의 홈에 결착되게 함으로써 핀이 빠지지 않도록 하는 것이다.Therefore, when the pin is inserted or pulled out, the fastener is erected so as not to be caught in the groove formed in the pin head, and the pin is laid down so that the fastener is fixed to the groove of the pin head so that the pin does not fall out.

따라서 핀이 끼원진 상태에서 진동이 있더라도 핀 머리에 형성된 홈에 고정구가 결착되어 핀을 누르고 있으므로 핀이 저절로 빠지지 않게 되고, 핀을 뽑을 때는 고정구를 세워서 핀 머리에 형성된 홈에서 이탈되게 한 후 핀 머리의 홈을 잡고 뽑으면 되므로, 별다른 공구 없이도 간단하게 핀을 뽑아 낼 수 있게 되는 것이다.Therefore, even if there is vibration in the pinned state, the fixture is fixed to the groove formed in the pin head and the pin is held down so that the pin does not fall out by itself. You can simply pull out the pin without any tools because you can pull it out.

이하 본 고안을 첨부한 예시 도면을 참조하여 자세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도의 (a)는 본 고안에 따른 핀 이탈 방지장치가 설치된 상태의 평면도이며, 제1도의 (b)는 그 측면 개념도로서, 핀(1)이 끼워지면 핀 머리(2)의 외주면에 형성되어 있는 홈(3)에 고정물 본체(4)에 설치된 고정구(5)가 결착되어, 핀(1)은 고정구(5)의 결착을 해제하지 않는 한 스스로 빠질 수 없도록 되어 있다.(A) of FIG. 1 is a plan view of a state in which the pin release prevention device according to the present invention is installed, and (b) of FIG. 1 is a side view of the pin, and is formed on the outer circumferential surface of the pin head 2 when the pin 1 is fitted. The fastener 5 provided in the fixture main body 4 is fastened to the groove | channel 3 which is made, and the pin 1 cannot be pulled out by itself unless the fastener 5 is released.

상기 홈(3)의 형상은 윗면은 비스듬한 경사면으로 되어 있고 아랫면은 원호형의 곡면으로 되어 있어서, 고정구(5)가 세워지거나 눕혀질 때 방해받지 않도록 되어 있다.The shape of the groove 3 is an oblique inclined surface on the upper surface and an arced curved surface on the lower surface of the groove 3 so as not to be disturbed when the fixture 5 is standing or lying down.

한편 상기 핀(1)을 고정시키는 고정구(5)의 구조는 고정물 본체(4)에 두개의 지지 브라케트(6)가 고정설치되고, 그 사이에 고정구(5)가 축회전할수 있도록 고정구 결합핀(7)에 의해 결합되어 이루어져 있다.Meanwhile, the structure of the fastener 5 for fixing the pin 1 has two support brackets 6 fixed to the fixture body 4, and the fastener coupling pins allow the fastener 5 to be axially rotated therebetween. It is composed by (7).

그리고 상기 고정구(5)의 형상은 핀 머리(2)에 형성되어 있는 홈(3)에 결착되기 쉽도록 아랫면이 홈(3)의 아랫면과 같은 원호형의 곡면으로 되어 있고, 결착된 상태에서 핀(1)이 빠지는 방향으로는 회전하지 않도록, 고정구(5)가 눕혀진 상태에서 고정물 본체(4)에 닿는 부분이 길게 되어 있으며, 고정구(5)를 세우거나 눕히는 조작을 쉽게 할 수 있도록 손잡이(8)가 달려져 있다.And the shape of the fastener (5) is an arc-shaped curved surface, such as the lower surface of the groove 3, the lower surface is easy to be bound to the groove (3) formed in the pin head (2), the pin in the bound state In order to prevent rotation in the direction in which (1) is pulled out, the part which touches the fixture main body 4 in the state in which the fastener 5 is lying down is long, and a handle (for easy operation of raising or lowering the fastener 5) ( 8) is up.

제2도는 본 고안의 핀 이탈 방지장치가 세워진 상태의 측면 개념도로서, 핀의 탈착 작업을 위해 고정구(5)를 회전시켜 세워서 홈(3)과 결착을 해제한 것이다. 핀을 뽑을 때에는 이와 같이 고정구(5)를 세운 상태에서 손으로 핀 머리(2)를 잡아 당겨 핀(1)을 뽑을 수 있고, 핀을 끼울 때에는 고정구(5)를 세운 상태에서 핀을 끼운 다음 고정구를 눕히면 된다.Figure 2 is a side conceptual view of the pin release prevention device of the present invention is set up, to release the fasteners (3) by releasing the fasteners (5) to rotate for the removal operation of the pins. When pulling out the pin, you can pull out the pin (1) by pulling the pin head (2) with your hand in the upright (5) upright, and when inserting the pin, insert the pin with the upright (5) upright, and then Just lay down.

상기한 바와 같은 핀 이탈 방지장치를 설치함으로써, 진동이 심한 곳에서도 핀이 저절로 빠지는 것을 막을 수 있게 되고 핀을 끼우고 뽑는 작업을 별도의 공구를 사용하지 않고도 용이하게 할 수 있게 되는 것이다.By installing the pin departure prevention device as described above, it is possible to prevent the pin from falling out spontaneously even in the place where the vibration is severe, and to facilitate the pinning and unplugging operation without using a separate tool.
