이러한 구성으로 이루어진 본 발명의 방진조립체(30)에 의한 작용을 설명하면 다음과 같다. The action of the vibration-proof assembly 30 of the present invention having such a configuration will be described as follows.

도 10에 도시된 바와 같이 본 발명의 방진조립체(30)를 방진판(40)에 고정 설치하고, 방진조립체(30)의 조임나사(35)를 외측 구동브라켓(12)의 나사구멍(12b)에 나사맞춤시킨 상태에서 강도조절링(34)을 회전시키면 강도조절링(34)의 끝단(34b)과 외측 구동브라켓(12)의 접촉면(12a) 사이의 간격(d)을 조절할 수 있다.As shown in FIG. 10, the vibration-proof assembly 30 of the present invention is fixed to the vibration-proof plate 40, and the screw 35 of the vibration-proof assembly 30 is installed in the screw hole 12b of the outer drive bracket 12. When the strength control ring 34 is rotated in the state screwed to the , the distance d between the end 34b of the strength control ring 34 and the contact surface 12a of the outer drive bracket 12 can be adjusted.

예를 들어 가압판(33)의 나사구멍(33b)에 나사부(34a)가 나사맞춤된 강도조절링(34)을 회전시켜 가압판(33)이 방진부재(32)를 가압하지 않고 가압판(33)의 외측면(33a)이 방진부재(32)의 내측면(32b)에 접촉만하는 상태를 강도 '0'라고 가정할 때, 도 9에서와 같이 강도조절링(34)의 슬롯(34c)이 가압판(33)의 표시눈금(33c)중 3시와 9시 위치에 있는 표시눈금(33c)과 일치되도록 하고, 이 상태에서 도 10에서와 같이 강도조절링(34)의 끝단(34b)과 외측 구동브라켓(12)의 접촉면(12a) 사이에 간격(d)이 형성되도록 미리 셋팅하여 설치한다.For example, the pressure plate 33 rotates the strength control ring 34 in which the screw portion 34a is screwed into the screw hole 33b of the pressure plate 33, so that the pressure plate 33 does not press the vibration-proof member 32. When it is assumed that the strength of the outer surface 33a only contacts the inner surface 32b of the vibration-proof member 32 is '0', the slot 34c of the strength control ring 34 is the pressure plate as shown in FIG. 9 . Make it coincide with the display scale 33c at the 3 o'clock and 9 o'clock positions among the display scales 33c of (33), and in this state, the end 34b of the strength control ring 34 and the outer drive as shown in FIG. It is installed in advance so that a gap (d) is formed between the contact surfaces (12a) of the bracket (12).

이 상태에서 도 9에서와 같이 강도조절링(34)의 슬롯(34c)을 이용하여 강도조절링(34)을 정,역방향으로 회전시키면, 나사부(34a)와 나사구멍(33b)에 의해서 가압판(33)에 대하여 강도조절링(34)이 전,후진방향으로 이동하므로, 강도조절링(34)의 끝단(34b)과 외측 구동브라켓(12)의 접촉면(12a) 사이의 간격(d)을 조절할 수 있으며, 강도조절링(34)은 가압판(33)과 나사맞춤되어 이동하는 것이므로, 나사부(34a)와 나사구멍(33b)의 피치를 설정하는 것에 의해 강도조절링(34)의 회전각도에 따른 전,후진방향의 이동거리를 계산할 수 있고, 이를 복수개의 표시눈금(33c)으로 세분화하여 간격(d)을 미세조절할 수 있다.In this state, when the strength control ring 34 is rotated in the forward and reverse directions using the slot 34c of the strength control ring 34 as in FIG. 9, the pressure plate ( 33), since the strength control ring 34 moves in the forward and backward directions, the distance d between the end 34b of the strength control ring 34 and the contact surface 12a of the outer drive bracket 12 can be adjusted Since the strength control ring 34 moves by being screw-fitted with the pressure plate 33, by setting the pitch of the screw portion 34a and the screw hole 33b, the strength control ring 34 according to the rotation angle The moving distance in the forward and backward directions can be calculated, and the interval d can be finely adjusted by subdividing it into a plurality of display scales 33c.

강도조절링(34)의 끝단(34b)과 외측 구동브라켓(12)의 접촉면(12a) 사이의 간격(d)을 설정한 후, 조임나사(35)를 회전시켜 조이게 되면, 강도조절링(34)을 외측 구동브라켓(12)쪽으로 이동시킬 수 있게 되고, 강도조절링(34)의 이동으로 도 8에 도시된 바와 같이 강도조절링(34)의 끝단(34b)이 외측 구동브라켓(12)의 접촉면(12a)에 점점 근접하여 접촉하게 되면, 접촉과 동시에 조임나사(35)를 회전시키기 위한 토오크가 급격히 상승하게 되므로 더 이상 회전시키는 것이 어렵게 되고, 이를 사용자가 인식하여 강도조절링(34)의 회전을 멈춤으로써 정확하게 설정된 간격(d) 만큼 강도조절링(34)을 이동시킬 수 있다.After setting the distance d between the end 34b of the strength control ring 34 and the contact surface 12a of the outer drive bracket 12, when the tightening screw 35 is rotated to tighten, the strength control ring 34 ) can be moved toward the outer drive bracket 12, and as shown in FIG. When the contact surface 12a is brought into closer contact, the torque for rotating the pressure screw 35 rapidly increases at the same time as the contact surface 12a, so it is difficult to rotate it any more, and the user recognizes this and By stopping the rotation, it is possible to move the intensity control ring 34 by an accurately set interval (d).

따라서, 강도조절링(34)이 이동한 간격(d) 만큼 가압판(33)이 이동하여 방진부재(32)를 가압하여 압축시키게 되므로, 방진부재(32)는 도 10에서와 같이 압축전 두께(a1)보다 도 8에서와 같이 압축후 두께(a2)로 좁아지게 되어 강도가 압축량 만큼 증가된다. 즉 강도조절링(34)의 회전량으로 간격(d)을 설정하는 것에 의해 방진부재(32)의 강도를 조절할 수 있게 된다.Therefore, since the pressure plate 33 moves by the interval d at which the strength control ring 34 is moved to press and compress the vibration-proof member 32, the vibration-proof member 32 has a thickness before compression ( After compression as shown in FIG. 8 rather than a1), it becomes narrower to the thickness a2, so that the strength is increased by the amount of compression. That is, it is possible to adjust the strength of the anti-vibration member 32 by setting the interval d by the amount of rotation of the strength control ring 34 .

이와 같이 본 발명의 방진조립체(30)는 방진부재(32)의 강도(완충력)가 조절되므로, 관측장비의 종류 또는 규격마다 외부에서 전자광학센서(2)로 유입되는 진동을 미리 측정한 값에 오차가 발생하여 강도가 잘못 설정된 방지구(13)를 설치함으로써 사용시 외부에서 전자광학센서(2)로 미세한 진동이 유입될 경우, 방진부재(32)의 강도를 조절하여 진동 유입을 확실하게 차단할 수 있고, 이로 인해 안정된 열영상을 제공할 수 있다.As described above, in the vibration-proof assembly 30 of the present invention, since the strength (buffering force) of the vibration-proof member 32 is adjusted, the vibration flowing into the electro-optical sensor 2 from the outside is measured in advance for each type or standard of observation equipment. When a fine vibration is introduced into the electro-optical sensor 2 from the outside during use by installing the preventive device 13 whose strength is set incorrectly due to an error, the inflow of vibration can be reliably blocked by adjusting the strength of the vibration-proof member 32 Thereby, it is possible to provide a stable thermal image.

또한 기존에 설치된 방진구(13)가 파손될 경우, 동일한 기존의 방진구(13)로 교체할 경우 또 다시 파손될 염려가 있지만, 본 발명의 방진조립체(30)로 교체하여 강도를 더욱 강화시키게 되면, 방진구(13)가 또 다시 파손되는 것을 방지할 수 있어 방지구(13) 교체로 인한 번거로움을 해소하고 유지비용을 절감할 수 있다.In addition, if the previously installed anti-vibration sphere 13 is damaged, there is a risk that it will be damaged again when replaced with the same existing anti-vibration sphere 13. Since it is possible to prevent the anti-vibration sphere 13 from being damaged again, it is possible to eliminate the inconvenience of replacing the anti-vibration sphere 13 and reduce the maintenance cost.
