Title: OPTICAL DEVICE ROTATING DEVICE
Abstract:
The present invention relates to an optical device rotating device which, when capturing an image or photographing a picture, may be used not only by being mounted on an optical device and coupled to a clamp of a ball head or a clamp of a support, but also by being coupled to another device having a coupling part configuration part (14), thereby enabling the rotating or stopping of the optical device according to a frictional force that is directly controlled by a user. The rotating device comprises a bearing part (17) having a thrust bearing (17-1) enabling one portion of a body (15) to be positioned in a groove (16) while the one portion of the body (15) passes through the inside of the thrust bearing (17-1), the groove (16) being configured in a direction where a head part (15-1) of the body (15) is configured inside a housing. When using the rotating device by coupling a coupling part (15-2) to an optical device (9) or to a coupling part configuration part (14) provided to a device (8) that may be coupled to the optical device, and coupling same to a clamp coupling part (13) on a fixed clamp (10), the thrust bearing (17-1) is a means for preventing uncoupling from the coupling part configuration part (14) when the coupling part (15-2) of the body (15) coupled to the coupling part configuration part (14) rotates the optical device (9) by applying external force thereto, and for enabling the optical device (9) to be rotated according to a frictional force directly controlled by a user by pressurizing or reducing the pressure of a friction rotation part (18) by using a tool and a tool insertion groove (15-4) provided to the head part (15-1) of the body (15). Further, the rotating device is provided with a bearing protection plate (17-4) capable of protecting a bearing support plate (17-3) in order to prevent damage thereto due to force acting on the head part (15-1) of the body (15) when pressurizing the thrust bearing (17-1) in the direction of the head part (15-1) of the body (15). Thus, when an optical device is rotated by coupling the rotating device mounted on the optical device to a tripod or a clamp of a support, a rotating function may be provided according to a required frictional force that is directly controlled by a user by using a tool, and the rotating device may be coupled to another device having a coupling part configuration part in order to quickly and conveniently photograph an image or picture while rotating the optical device.
