Abstract

본 고안은 감시용 카메라의 렌즈 취부구조에 관한 것으로서, 특히 렌즈 마운트에 C마운트 렌즈와 CS마운트 렌즈를 공용으로 취부할 수 있도록 개량한 기술이다.The present invention relates to a lens mounting structure of a surveillance camera, in particular an improved technology to mount a C mount lens and a CS mount lens in common to the lens mount.

기존에는 렌즈마운트가 C마운트와 CS마운트의 구조로 된 렌즈가 생산됨에 따라 C마운트로된 감시용 카메라는 가격이 비싸게 되므로 사용자가 필요에 따라 C마운트의 카메라와 CS마운트 카메라를 각각 구입하여 사용하여야 하는 문제점이 있어 이를 해결하기 위하여 렌즈 마운트가 C마운트와 CS마운트를 공용으로 조립, 분해할 수 있도록 하여 사용자가 하나의 카메라에 원하는 렌즈 마운트를 교환하여 감시용 카메라를 편리하게 사용할 수 있는 것이다.In the past, as lens mounts are manufactured with C mount and CS mount lenses, surveillance cameras with C mounts are expensive, so users must purchase and use C mount cameras and CS mount cameras as needed. In order to solve this problem, the lens mount allows the C mount and the CS mount to be assembled and disassembled in common so that the user can conveniently use the surveillance camera by exchanging a desired lens mount in one camera.

본 고안은 감시용 카메라의 렌즈 취부 구조에 관한 것으로서, 특히, 렌즈 마운트에 C마운트 렌즈와 CS마운트 렌즈를 공용으로 취부할 수 있도록 개량한 것이다.The present invention relates to a lens mounting structure of a surveillance camera, and in particular, improved to mount a C mount lens and CS mount lens in common to the lens mount.

종래에는 제1도에 도시한 바와 같이 감시용 카메라에 있어서 카메라 렌즈 마운트(21)가 원통형을 이룬 중앙 외주에 각각의 세트스크류(23)을 체결하는 스크류구멍(22)을 이루고 중앙 홀(24) 내측에 나선(25)을 형성하고, 고정 렌즈 마운트(26)는 외주 중앙에 세트 스크류(23) 체결홈(27)과 선착측에 나선(28)을 이루고 중앙홀(29)에 후단측에 나선(30)을 형성하여 상기 카메라 렌즈 마운트(21)의 중앙홀(24)에 형성된 내측 나선(25)에 고정 렌즈 마운트(26)의 선단측 나선(28)을 끼워 고정 렌즈 마운트(26)을 회전시키며 촛점을 맞추고 스크류구멍(22)를 통하여 세트스크류(23)로 카메라 렌즈 마운트(21)와 고정렌즈마운트(26)을 고정시키고 고정렌즈마운트(26)의 중앙홀(29)에 렌즈부를 고정시키는 것이다.Conventionally, in the surveillance camera, as shown in FIG. 1, the camera lens mount 21 forms a screw hole 22 for fastening the respective set screws 23 to the center circumference of a cylindrical shape, and the center hole 24. The spiral 25 is formed on the inner side, and the fixed lens mount 26 forms the set screw 23 fastening groove 27 at the center of the outer circumference and the spiral 28 at the first arrival side, and the spiral at the rear end side at the central hole 29. 30 to rotate the fixed lens mount 26 by inserting the tip side spiral 28 of the fixed lens mount 26 into the inner spiral 25 formed in the center hole 24 of the camera lens mount 21. Focusing and fixing the camera lens mount 21 and the fixed lens mount 26 with the set screw 23 through the screw hole 22 and to fix the lens portion in the center hole 29 of the fixed lens mount 26 will be.

상기와 같은 C마운트는 렌즈의 촛점거리가 렌즈의 기준면에서 결상면까지의 거리가 대략 17.526mm인 것이다.In the C-mount as described above, the focal length of the lens is approximately 17.526 mm from the reference plane of the lens to the image plane.

상기와 같은 감시용 카메라에 있어서 렌즈 마운트가 C마운트 한 종류로 생산되었으나 단가면에서 유리한 CS마운트 구조의 렌즈가 생산됨에 따라 기존에 사용된 C마운트로된 감시용 카메라는 가격이 비싸게 되므로 사용자가 필요에 따라 C마운트의 감시용 카메라와 CS마운트의 감시용 카메라를 각각 구입하여 사용하여야 하는 불편한 문제점이 있었다.In the surveillance camera as described above, the lens mount was produced as a C-mount type, but the CS-mounted lens for the CS mount structure, which is advantageous in terms of cost, is produced. Therefore, the C-mount surveillance camera is expensive and requires a user. In accordance with the C-mount surveillance cameras and CS mount surveillance cameras had to purchase and use the inconvenience, respectively.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 전자에 해당되는 기존 C마운트 구조를 개선하여 C마운트와 CS마운트를 공용으로 사용할 수 있도록 렌즈 마운트를 형성하여 사용자가 편리하게 사용할 수 있도록 본 고안의 목적이 있다.The present invention has been devised to solve the above problems, by improving the existing C mount structure corresponding to the former to form a lens mount to use the C mount and CS mount in common to the user to use conveniently There is a purpose.

상기와 같은 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for achieving the above object will be described in detail with reference to the accompanying drawings.

Tighten it tightly to) so that the C mount 6 is fixed to the lens mount 1 so as not to move.

이때 렌즈의 촛점거리가 렌즈의 기준면에서 결상면까지 대략 17.526mm이어야 한다.At this time, the focal length of the lens should be approximately 17.526mm from the reference plane of the lens to the imaging plane.

상기와 같은 상태에서 렌즈마운트(1)에 CS마운트(11)를 사용하고자 할 때에는 렌즈마운트(1)의 중앙 홀(4)에 결합된 C마운트(6)를 빼내고 CS마운트(11)의 선단측에 형성된 나선(13)과 상기 렌즈마운트(1)의 중앙홀(4)에 끼워 회전시켜 렌즈의 촛점 거리를 맞춘 후 CS마운트(11)가 움직이지 않도록 스크류구멍(2)를 통해 세트스크류(3)로 체결홈(12)에 밀착되게 조여 렌즈마운트(1)에 CS마운트(11)가 움직이지 않도록 고정시켜 사용하는 것이다.When the CS mount 11 is to be used for the lens mount 1 in the above state, the C mount 6 coupled to the center hole 4 of the lens mount 1 is removed and the tip side of the CS mount 11 is removed. The set screw (3) through the screw hole (2) so that the CS mount (11) does not move after adjusting the focal length of the lens by rotating by screwing in the spiral (13) formed in the center hole (4) of the lens mount (1) Tighten to be in close contact with the fastening groove 12 by using a fixed to the lens mount (1) so that the CS mount 11 does not move.

이때 CS마운트 렌즈의 촛점거리가 렌즈의 기준면에서 결상면까지 대략 12.5mm이어야 한다.In this case, the focal length of the CS mount lens should be approximately 12.5 mm from the reference plane of the lens to the imaging plane.

상기와 같은 본 고안에 의하면 감시용 카메라의 렌즈마운트에 C마운트와 CS마운트를 공용으로 조립, 분해할 수 있도록 하여 사용자가 원하는 렌즈 마운트 교환하여 감시용 카메라를 편리하게 사용할 수 있으며 CS마운트를 사용시 촛점거리가 짧아지므로 소형 경량화와 저가격으로 사용할 수 있는 잇점이 있다.According to the present invention as described above, the C mount and CS mount can be commonly assembled and disassembled in the lens mount of the surveillance camera so that the user can conveniently use the surveillance camera by changing the lens mount that the user desires, and focus on using the CS mount. As the distance is shortened, there is an advantage that it can be used at small weight and low cost.
