Description

고정볼트의 풀림 방지장치{A loosing prevention device for a fastened bolt}A loosing prevention device for a fastened bolt}

본 고안은 물체와 물체를 고정시키기 위하여 체결된 고정볼트가 진동 등의 외력에도 쉽게 풀리지 않도록 한 고정볼트의 풀림 방지장치에 관한 것이다.The present invention relates to an anti-loosening device of a fixing bolt that is fastened so that the fixing bolt fastened to fix the object and the object is not easily released even by external force such as vibration.

물체와 물체를 고정시키는 방법으로는 여러 가지의 방법이 있지만 볼트체결방식에 의하여 고정시키는 방법이 간단하면서도 설치비용이 적게 들어 주로 사용되고 있는데 이러한 볼트체결방식은 진동 등의 외력으로 체결된 볼트가 조금씩 풀려 조임력이 느슨해짐으로써 작업이 끝날때 까지 물체와 물체를 단단히 고정하지 못하는 단점이 있어 정밀도를 요하는 작업 등에는 사용하지 못하는 문제점이 있었다.There are various methods of fixing objects and objects, but the method of fixing by bolt fastening method is simple and is mainly used because of low installation cost. This bolt fastening method is loosened by the bolts fastened by external force such as vibration little by little. As the tightening force is loosened, there is a problem in that the object and the object are not firmly fixed until the end of the work, so there is a problem that cannot be used for work requiring precision.

본 고안은 이러한 문제점을 해소하고자 하는 것으로 보다 상세하게는 물체를 고정시키기 위하여 체결된 고정볼트가 진동 등의 외력에도 쉽게 풀리지 않아 단단한 고정력을 유지하도록 하는데 특징이 있다.The present invention is intended to solve this problem in more detail is characterized in that the fastening bolt fastened to fix the object is not easily loosened by external forces such as vibration to maintain a firm fixing force.

이러한 목적을 달성하기 위하여 본 고안에서는 고정볼트에 고정핀 삽입홈이 형성되어 있는 회전방지단을 부착하고, 고정볼트의 일측에 고정핀돌출장치를 형성하되 고정핀돌출장치는 고정핀과 스프링으로 구성하여 스프링의 탄성력으로 고정핀이 고정볼트방향으로 밀리도록 함으로써 고정볼트를 사용하여 물체와 물체를 단단히 조인 후 고정핀돌출장치의 고정핀을 고정볼트 상부에 부착된 회전방지단의 고정핀 삽입홈에 끼워 진동 등의 외력이 작용하여도 고정볼트가 풀어지지 않도록 하는데 특징이 있다.In order to achieve this purpose, the present invention attaches the anti-rotation end in which the fixing pin insertion groove is formed on the fixing bolt, and forms a fixing pin protrusion on one side of the fixing bolt, but the fixing pin protrusion is composed of the fixing pin and the spring. By pushing the fixing pin in the direction of the fixing bolt by the elastic force of the spring. It is characterized in that the fixing bolt is not released even when external force such as vibration is inserted.

본 고안을 도면에 의하여 설명하면 다음과 같다.Referring to the present invention by the drawings as follows.

본 고안의 장치는 고정볼트(1)와 고정핀돌출장치(2)로 구성되어 있는데 고정볼트(1)는 그 상부에 상, 하 직선의 산과 골로된 다수 개의 고정핀 삽입홈(3)이 주위에 형성되어 있는 회전방지단(4)이 용접으로 부착되어 있고, 고정핀돌출장치(2)는 고정핀(5)과 스프링(6)으로 구성되어 스프링(6)의 탄력으로 고정핀(5)이 고정볼트 방향으로 밀리도록 되어 있어 회전방지단(4)이 부착된 고정볼트(1)를 사용하여 물체(9a)와 물체(9b)를 단단히 조인 후 고정핀돌출장치(2)의 고정핀(5)을 고정볼트(1)에 부착된 회전방지단(4)의 고정핀 삽입홈(3)에 끼워지도록 하여 진동 등의 외력이 작용하여도 고정볼트(1)가 풀어지지 않도록 되어 있다.The device of the present invention is composed of a fixing bolt (1) and a fixing pin protrusion (2), the fixing bolt (1) has a plurality of fixing pin insertion grooves (3) of the hills and valleys of the upper and lower straight lines on the top The anti-rotation end (4) formed in the welding is attached, the fixed pin protrusion device (2) is composed of a fixing pin (5) and the spring (6) to the elasticity of the spring (6) fixing pin (5) It is pushed in the direction of the fixing bolt, and the object 9a and the object 9b are firmly fastened using the fixing bolt 1 with the anti-rotation end 4 attached thereto, and then the fixing pin of the fixing pin protrusion 2 5) is inserted into the fixing pin insertion groove 3 of the anti-rotation end 4 attached to the fixing bolt 1 so that the fixing bolt 1 is not released even when external force such as vibration is applied.

본 고안의 장치 각 부분을 보다 구체적으로 설명하면 다음과 같다.Hereinafter, each part of the device of the present invention will be described in detail.

고정볼트(1)의 상부에는 회전방지단(4)을 부착하고 이 회전방지단(4)에는 고정핀 삽입홈(3)이 형성되어 있는데 고정핀 삽입홈(3)의 수가 적을 수록 고정볼트(1)의 움직임을 고정시킬 수 있는 효율이 떨어지므로 고정핀 삽입홈(3)은 되도록 많이 형성하여 고정볼트(1)의 작은 움직임에도 고정핀 삽입홈(3)에 고정핀(5)을 안정적으로 끼울 수 있도록 하는 것이 바람직하다.An anti-rotation end 4 is attached to the upper part of the fixing bolt 1, and a fixing pin insertion groove 3 is formed in the anti-rotation end 4, and as the number of the fixing pin insertion grooves 3 decreases, the fixing bolt ( 1) Since the efficiency of fixing the movement is inferior, the fixing pin insertion groove 3 is formed as much as possible so that the fixing pin 5 is stably fixed to the fixing pin insertion groove 3 even in the small movement of the fixing bolt 1. It is desirable to be able to fit.

고정핀돌출장치(2)는 고정하고자 하는 물체에 부착되어 있으며 몸체(7)에 스프링(6)이 끼워지고 스프링(6)의 앞쪽에 고정핀(5)이 끼워지도록 하여 고정핀(5)이 스프링(6)의 탄성력에 의하여 앞쪽으로 밀려나와 고정핀(5)이 고정볼트(1)의 회전방지단(4)에 형성된 고정핀 삽입홈(3)에 끼워져 고정볼트(1)가 회전하지 못하도록 하되 고정볼트(1)를 풀거나 조일 때에는 고정볼트(1)에 의한 영향을 받지 않도록 하기 위하여 스프링(6)을 뒤로 밀어서 고정시킬 수 있는 스프링 압축고정수단을 구비한다. 미설명 부호 8은 스프링을 밀어주기 위한 손잡이다.The fixing pin protrusion 2 is attached to the object to be fixed, and the fixing pin 5 is inserted into the body 7 so that the spring 6 is fitted and the fixing pin 5 is fitted in front of the spring 6. The fixing pin 5 is pushed forward by the elastic force of the spring 6 to be inserted into the fixing pin insertion groove 3 formed in the anti-rotation end 4 of the fixing bolt 1 so that the fixing bolt 1 cannot be rotated. However, when loosening or tightening the fixing bolt (1) is provided with a spring compression fixing means that can be fixed by pushing the spring (6) in order not to be affected by the fixing bolt (1). Reference numeral 8 is a handle for pushing the spring.

본 고안에 의하면 고정볼트에 고정핀 삽입홈이 형성되어 있는 회전방지단을 형성하고, 고정볼트의 옆에 고정핀과 스프링으로 구성되어 스프링의 탄성력으로 고정핀이 앞으로 밀려 고정핀이 회전방지단에 형성된 고정핀 삽입홈에 끼워지도록 되어 있는 고정핀돌출장치를 설치하여 고정핀 삽입홈에 고정볼트를 끼워 진동 등의 외력이 작용하여도 고정볼트가 풀어지지 않도록 함으로써 설치가 간단하고 저렴한 고정볼트의 풀림 방지장치를 제공할 수 있다.According to the present invention, the fixing bolt is formed with a fixing pin insertion groove formed in the anti-rotation end, and the fixing pin is composed of a fixing pin and a spring next to the fixing bolt, and the fixing pin is pushed forward by the elastic force of the spring so that the fixing pin is fixed to the rotation preventing end. Installation of a fixed pin protrusion that is to be inserted into the formed fixed pin insertion groove to insert the fixed bolt into the fixed pin insertion groove so that the fixing bolt is not released even when external force such as vibration is applied. A prevention device can be provided.
