Embodiment Construction
[0014] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] Depend on Figure 1 to Figure 7 Given, the present invention includes a rectangular housing 1, a horizontal first rotating shaft 2 is installed in the housing 1 along the left and right directions, a first bevel gear 3 is installed on the first rotating shaft 2, and a first bevel gear 3 is installed on the top wall of the housing 1. There is a vertical second rotating shaft 4, the second rotating shaft 4 lower end is equipped with a second bevel gear 5, the second bevel gear 5 meshes with the first bevel gear 3, the upper end of the second rotating shaft 4 stretches out of the housing 1 and A horizontal stage 6 is fixed; a friction wheel 7 located on the left side of the first bevel gear 3 is mounted on the first rotating shaft 2, and the friction wheel 7 can slide left and right on the first rotating shaft 2. The...

The invention relates to a photographic pan-tilt rotation unit with step-down control, which effectively solves the problem that it is difficult to control the speed and stabilize the lens when panning the camera for shooting; The stage is installed, and the rotating shaft can drive the stage to rotate. A friction wheel is installed on the hollow sleeve of the rotating shaft. There is a tapered hole on the wheel axis, and a tapered block is arranged in the tapered hole. The tapered block is slidably installed on the rotating shaft through the sliding key. The tapered block can be moved left and right to realize the compression and Detachment; the present invention can adapt to the needs of all film and television panning shots. When shooting large-angle panning shots, the photographer does not need to sway the body with the lens, which can avoid the instability of the lens caused by the large swing of the body, and at the same time avoid the soreness of the arm when shooting for a long time .
Description
technical field [0001] The invention relates to the field of photographic equipment, in particular to a photographic pan-tilt rotation unit with step-down control. Background technique [0002] Panning is a commonly used form of shooting in photography. It refers to the shot taken by moving the optical lens axis of the camera horizontally or vertically without moving the camera position. It is similar to the way people stand and shake their heads. The application of horizontal roll is more common, and horizontal roll can be divided into: used to highlight key points or connect things in series, with intermittent shaking with several pauses in the middle; used to speed up or slow down the rhythm, and the shaking speed gradually increases or decreases Variable speed panning; used for shooting panoramas, the camera rotates a circular panning; used to create a tense atmosphere, the "flick" lens with extremely fast panning speed; and chasing panning for a certain live animal, etc...
