렌즈계 원근 조절장치{.}Lens system perspective adjuster {.}

본 발명은 카메라,캠코드,망원경 등에 적용되는 렌즈계 원근 조절장치에 관한 것으로서, 특히 유압의 증감에 의해 렌즈가 고정된 상태로 수축 및 팽창하여 피사체의 초점 및 배율이 조절되는 렌즈계 원근 조절장치에 관한 것이다.The present invention relates to a lens system perspective adjusting device applied to a camera, a cam cord, a telescope, and the like, and more particularly, to a lens system perspective adjusting device in which the focus and magnification of a subject are adjusted by contracting and expanding the lens in a fixed state by increasing or decreasing hydraulic pressure. .

일반적으로 카메라,캠코더를 비롯한 광학계는 다수의 렌즈를 배치하고, 이러한 렌즈계는 원근 조절장치에 의해 피사체의 선명도가 확보된 상태로 피사체의 조점 및 배율이 조정되도록 한다.In general, an optical system, such as a camera and a camcorder, arranges a plurality of lenses, and the lens system allows the focus and magnification of the subject to be adjusted while the sharpness of the subject is secured by the perspective adjusting device.

이러한 종래의 렌즈계의 원근조절은 렌즈가 배치되는 조절구를 수작업으로 조절하거나 이러한 조절구의 조절이 자동으로 조절되도록 하여 피사체의 초점 및 배율을 맞추었다.The perspective control of the conventional lens system adjusts the control mechanism in which the lens is disposed manually or adjusts the adjustment of the control mechanism to adjust the focus and magnification of the subject.

그러나 종래의 렌즈의 원근조절 장치는 렌즈가 배치되는 조절구와 이송수단을 유기적으로 연결하여 이 이송수단에 의해 렌즈가 전후방향으로 이송되는 구조로서, 유기적으로 연결되는 여러부품에 의해 구조가 복잡함은 물론 렌즈의 이송거리를 확보하게 되어 렌즈를 배치한 제품이 전체적으로 부피가 커지는 문제점이 있었다.However, the conventional lens perspective control device is a structure in which the lens is disposed in the front and rear direction by organically connecting the control mechanism and the transfer means is disposed, the structure is complicated by the various parts that are organically connected There was a problem in that the lens is secured to transport distance of the lens disposed product is bulky overall.

본 발명은 상기한 문제점을 해결하기 위하여 안출한 것으로서, 본 발명의 목적은 카메라,캠코드,망원경 등에 적용되는 렌즈계가 렌즈의 이송없이 유압의 증감에 의해 렌즈가 고정된 상태로 수축 및 팽창하여 피사체의 초점 및 배율이 조절되는 렌즈계 원근 조절장치를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is a lens system applied to a camera, a cam cord, a telescope, etc. shrinks and expands in a fixed state by the increase or decrease of the hydraulic pressure without moving the lens of the subject It is to provide a lens system perspective adjustment device that can adjust the focus and magnification.

상기 목적을 실현하기 위한 본 발명은 양측이 연통된 상태로 양측 내경에 내향지지단 및 키홈을 갖는 암나사산을 형성함과 함께 유체주입구를 구비한 경통, 경통의 키홈에 삽입되는 키돌기를 형성한 와셔, 경통의 암나사산에 체결되기 위한 수나사산을 형성하여 와셔를 통해 지지력을 제공하는 너트, 경통의 유체주입구와 연통하는 주입홀을 형성하여 경통의 내경에 장착되는 실링구를 갖추고, 상기 실링구에 밀착한 상태로 경통의 내향지지단과 와셔가 개재된 상태로 너트에 각각 지지되어 경통의 유체주입구 및 실링구의 주입홀을 통해 외부의 저장원으로부터 입출되는 투명체인 유체에 의해 수축 및 팽창되는 연질의 전면렌즈 및 후면렌즈를 특징적 구성으로 한다.The present invention for realizing the above object is to form a female thread having an inward support end and a key groove in the inner diameter of both sides in a state in which both sides are in communication with the barrel having a fluid inlet, the key projection is inserted into the key groove of the barrel The washer has a male thread for fastening to the female thread of the barrel and a nut providing support through the washer, and an injection hole communicating with the fluid inlet of the barrel to form a sealing hole mounted to the inner diameter of the barrel. It is supported by the nut with the inward support end and washer of the barrel in close contact with the nut, and is soft and contracted and expanded by the fluid, which is a transparent body that enters from the external storage source through the fluid inlet and the sealing inlet of the barrel.

이하, 본 발명의 실시예를 첨부한 도면 도1을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention will be described in detail as follows.

본 발명은 경통(10) 내에 전면렌즈(50)와 후면레즈를 한쌍으로 일정간격으로 배치하고, 렌즈 사이에 실링구(40)를 기밀히 유지되도록 삽입한 후 와셔(30)를 개재한 상태로 후면렌즈(55)의 후방으로부터 경통(10)에 체결되는 너트(20)에 의해 기밀히 체결하여, 상기 경통(10)과 실링구(40)를 통해 투명체인 유체를 출입되도록 하여 이 유체의 충진정도에 따라 렌즈의 구배율을 증감하도록 구성한다.In the present invention, the front lens 50 and the rear legs are arranged in a pair at a predetermined interval in the barrel 10, and the sealing holes 40 are inserted between the lenses to be kept airtight, with the washers 30 interposed therebetween. It is hermetically fastened by a nut 20 which is fastened to the barrel 10 from the rear of the rear lens 55, and the fluid which is transparent through the barrel 10 and the sealing opening 40 is allowed to enter and fill the fluid. It is configured to increase or decrease the gradient of the lens according to the degree.

즉, 경통(10)은 양측이 연통된 상태로 일측 내경에 내향지지단(12)를 형성하고 타측 내경에 암나사산(14)을 형성함과 암나사산(14)을 길이 방향으로 절개하여 형성된 적어도 하나 이상의 키홈(18)과 주벽의 소정위치에 내경과 외부와 연통하는 유체주입구(16)를 구비한다That is, the barrel 10 is formed by forming an inward support end 12 at one inner diameter and forming an internal thread 14 on the other inner diameter and cutting the female thread 14 in the longitudinal direction with both sides communicating. One or more keyways 18 and a fluid inlet 16 communicating with the inside and the outside at predetermined positions of the circumferential wall

그리고 와셔(30)는 내경에 경통(10)의 키홈(18)에 삽입되는 키돌기(32)를 형성한다. 너트(20)는 경통(10)의 암나사산(14)에 체결되기 위한 수나사산(22)을 형성한다.And the washer 30 forms a key protrusion 32 inserted into the key groove 18 of the barrel 10 in the inner diameter. The nut 20 forms a male screw thread 22 for fastening to the female screw thread 14 of the barrel 10.

실링구(40)는 유체주입구(16)와 연통하는 주입홀(42)을 형성하여 경통(10)의내경에 장착된다.The sealing port 40 forms an injection hole 42 in communication with the fluid inlet 16 and is mounted on the inner diameter of the barrel 10.

이러한 경통(10) 내부에는 실링구(40)에 밀착한 상태로 경통(10)의 내향지지단(12)과 와셔(30)가 개재된 상태로 너트(20)에 각각 지지되어 경통(10)의 유체주입구(16) 및 실링구(40)의 주입홀(42)을 통해 외부의 저장원으로부터 입출되는 투명체인 유체에 의해 수축 및 팽창되는 연질의 전면렌즈(50) 및 후면렌즈(55)가 장착된다.The barrel 10 is supported by the nut 20 in a state in which the inward support end 12 and the washer 30 of the barrel 10 are in close contact with the sealing opening 40, respectively, and the barrel 10 is provided. The soft front lens 50 and the rear lens 55 which are contracted and expanded by a fluid, which is a transparent body entering and exiting from an external storage source, through the fluid injection hole 16 and the injection hole 42 of the sealing hole 40 Is mounted.

이때 와셔(30)는 키돌기(32)가 경통(10)의 키홈(18)에 삽입된 상태로 너트(20)의 회전력에 의해 회전됨이 없이, 즉 회전이 방지됨으로서 전면렌즈(50) 및 후면렌즈(55)를 틀어짐이 없이 견고히 지지하게 된다.At this time, the washer 30 is not rotated by the rotational force of the nut 20 while the key protrusion 32 is inserted into the key groove 18 of the barrel 10, that is, the front lens 50 and the rotation is prevented. The rear lens 55 is firmly supported without being twisted.

따라서 유체가 경통(10)의 유체주입구(16) 및 실링구(40)의 주입홀(42)을 통해 주입되거나 배출되면, 실링구(40)에 밀착한 상태로 너트(20)으로 조여진 전면렌즈(50) 및 후면렌즈(55)는 밀착부재와 기밀을 유지한 상태로 볼록해지거나나, 오목해지거나, 평면을 이루는, 즉 구배율을 달리하여 피사체와 원근 및 배율을 달리한 상태에서 초점을 맞추게 된다.Therefore, when the fluid is injected or discharged through the fluid injection hole 16 of the barrel 10 and the injection hole 42 of the sealing hole 40, the front lens tightened by the nut 20 in close contact with the sealing hole 40. The 50 and the rear lens 55 are convex, concave, or planar in a state in which airtightness with the contact member is kept tight, that is, when the focal point and magnification are different from the subject by varying the gradient. Will be corrected.

본 발명은 렌즈계가 이송수단 없이 유압의 증감에 의해 렌즈가 고정된 상태로 수축 및 팽창하여 피사체의 초점 및 배율이 조절됨으로서, 구조적으로 간단함은 물론 소형 경량화가 가능한 효과가 있다.According to the present invention, the lens system is contracted and expanded in a fixed state in which the lens is fixed by the increase or decrease of hydraulic pressure without a conveying means, thereby adjusting the focus and magnification of the subject, thereby making it simple in structure as well as compact and lightweight.
