상기 각 보스(2)내에 설치된 압축스프링(3)의 바깥측 둘레면에는 탄성부재(4)가 삽입되어 있으며, 상기 탄성부재(4)의 상단은 보스(2)의 상부로 일정길이만큼 돌출되어 있다.An elastic member 4 is inserted into the outer circumferential surface of the compression springs 3 installed in the bosses 2, and an upper end of the elastic member 4 protrudes by a predetermined length to the upper part of the boss 2. have.
또한, 각 보스(2)의 홈부내에 삽입되어 보스(2) 상부로 돌출된 탄성부재(4)에는 음극선관(5)에 고정된 각 러그(6)가 얹혀지며, 상기 각 러그(6)의 상방으로 부터 러그(6)의 구멍을 통해 체결부재(7)를 삽입하여 조임방향으로 회전시킴에 따라 체결부재(7)가 압축스프링(3)에 체결됨과 동시에 러그(6)는 보스(2)의 상단면과 일정공간(S)만큼 떨어진 상태로 고정된다.In addition, each lug 6 fixed to the cathode ray tube 5 is mounted on the elastic member 4 inserted into the groove of each boss 2 and protruding upward from the boss 2, and the lugs 6 As the fastening member 7 is rotated in the tightening direction by inserting the fastening member 7 through the hole of the lug 6 from above, the fastening member 7 is fastened to the compression spring 3 and the lug 6 is the boss 2. It is fixed in a state spaced apart from the top surface of the predetermined space (S).
제4도와 같이 체결부재(7)의 나사홈간격인 피치(Pitch)(b)는 압축스프링(3)의 선과 선사이의 간격인 피치(a)보다 작게 형성되어 체결부재(7)를 조임에 따라 압축스프링(3)은 압축되도록 되어 있으며, 체결부재(7)가 완전히 조여진 상태에서도 체결부재(7)의 하단과 보스(2)의 홈부 바닥면 사이에는 공간(S)이 형성되도록 되어 있다.As shown in FIG. 4, the pitch (b), which is the interval between the thread grooves of the fastening member 7, is smaller than the pitch (a), which is the distance between the line and the line of the compression spring 3, so as to tighten the fastening member 7. The compression spring 3 is to be compressed, and the space S is formed between the lower end of the fastening member 7 and the bottom of the groove portion of the boss 2 even when the fastening member 7 is completely tightened.
상기와 같이된 본 고안은 음극선관(5)에 고정된 각 러그(6)가 탄성부재(4)가 얹혀진 상태에서 체결부재(7)를 조여주면 체결부재(7)가 압축스프링(3)에 체결되면서 음극선관(5)이 보스(2)에 고정되는 것으로, 체결부재(7)의 체결과정은 다음과 같다.According to the present invention as described above, when each lug 6 fixed to the cathode ray tube 5 tightens the fastening member 7 in a state where the elastic member 4 is placed, the fastening member 7 is connected to the compression spring 3. The cathode ray tube 5 is fastened to the boss 2 while being fastened, and the fastening process of the fastening member 7 is as follows.
제4a도는 체결부재(7)가 체결되기 전의 상태도로서, 이 상태에서 러그(6)의 구멍을 통해 체결부재(7)를 보스(2)내로 삽입하면 압축스프링(3)의 상단부가 체결부재(7)의 최하단 나사홈으로 끼워지게 된다.4A is a state diagram before the fastening member 7 is fastened. When the fastening member 7 is inserted into the boss 2 through the hole of the lug 6 in this state, the upper end of the compression spring 3 is fastened to the fastening member ( It will be inserted into the bottom screw groove of 7).
상기와 같이 압축스프링(3)의 상단부가 체결부재(7)의 하단 나사홈에 끼워진 상태에서 체결부재(7)를 조임방향으로 회전시키면 제4b도와 같이 압축스프링(3)이 나사홈에 감겨지면서 체결부재(7)가 점차 하방으로 이동하게 되는데, 이때 체결부재(7)의 피치(b)가 압축스프링(3)의 피치(a)보다 작기 때문에 압축스프링(3)은 점차 압축된다.As described above, when the fastening member 7 is rotated in the tightening direction while the upper end of the compression spring 3 is fitted into the lower screw groove of the fastening member 7, the compression spring 3 is wound around the screw groove as shown in FIG. The fastening member 7 gradually moves downward. At this time, since the pitch b of the fastening member 7 is smaller than the pitch a of the compression spring 3, the compression spring 3 is gradually compressed.
또한 체결부재(7)를 더욱 조여주면 제4c도와 같이 체결부재(7)의 머리부분이 러그(6)에 접속되면서 체결작업이 완료되고 러그(6)는 보스(6)에는 이탈하지 않게된다.Further tightening the fastening member 7 as shown in Figure 4c the head of the fastening member 7 is connected to the lug 6, the fastening work is completed and the lug 6 is not separated from the boss (6).
즉, 체결부재(7)를 조여주면 체결부재(7)가 압축스프링(3)에 결합되는데, 이 압축스프링(3)의 일단은 보스(2)에 인서트되어 보스(2)와 일체형으로 고정되어 있기 때문에 결국 체결부재(7)는 압축스프링(3)이라는 매개체를 통해 보스(2)에 체결되며, 따라서 러그(6)는 보스(2)에서 이탈하지 않게되는 것이다.That is, when the fastening member 7 is tightened, the fastening member 7 is coupled to the compression spring 3, and one end of the compression spring 3 is inserted into the boss 2 and fixed integrally with the boss 2. As a result, the fastening member 7 is fastened to the boss 2 through a medium called a compression spring 3, so that the lug 6 is not released from the boss 2.
상기와 같이 체결부재(7)의 체결이 완료된 상태에서도 체결부재(7)의 하단과 홈부의 바닥면 사이에는 공간(S)이 존재하게 되므로 음극선관(5)은 압축스프링(3)에 의해 상,하방향의 탄력을 받는 상태로 보스(2)에 지지된다.Even when the fastening of the fastening member 7 is completed as described above, a space S exists between the lower end of the fastening member 7 and the bottom surface of the groove, so that the cathode ray tube 5 is opened by the compression spring 3. , Is supported by the boss 2 in a state of receiving the elasticity of the downward direction.
또한 보스(2)의 상단과 러그(6) 사이에 공간(S)이 형성되어 체결부재(7)를 체결할 때 탄성부재(4)가 상,하 방향으로 압축되고 좌,우 방향으로 인장이 되므로 음극선관(5)에 좌,우방향으로 진동이 가해지는 경우에는 탄성부재(7)가 이를 흡수할 수 있게된다.In addition, a space S is formed between the upper end of the boss 2 and the lug 6 so that when the fastening member 7 is fastened, the elastic member 4 is compressed in the up and down directions and the tension is increased in the left and right directions. Therefore, when the vibration is applied to the cathode ray tube 5 in the left and right directions, the elastic member 7 can absorb it.
이상에서와 같이 본 고안은 음극선관에 가해지는 상,하방향의 진동은 압축스프링이 흡수하고 좌,우방향의 진동은 탄성부재가 흡수하여 보스에는 진동과 충격이 전달되지 않게되며, 따라서 진동이나 충격으로 인한 보스의 균열 및 파손을 방지할 수 있다.As described above, the present invention is the up and down vibrations applied to the cathode ray tube is absorbed by the compression spring and the left and right vibrations are absorbed by the elastic member so that the vibration and shock is not transmitted to the boss, so the vibration or It is possible to prevent the boss from cracking and breaking due to the impact.
