Description

Technical Field

[0001] The utility model relates to the technical field of camera brackets, in particular to a horizontal calibration structure of a video camera bracket. Background Art

[0002] Video camera stands are essential equipment in photography and videography, used to stabilize the camera, prevent shaking, and keep the camera precisely fixed at the desired angle and position. For professional photographers, ensuring that the camera is perfectly level is one of the keys to obtaining high-quality images.

[0003] The patent with publication number CN211779832U discloses a horizontal calibration bracket for camera shooting, which belongs to the technical field of calibration brackets. The horizontal calibration bracket for camera shooting includes a base, a fixing mechanism is welded on the outer wall of the base, a telescopic mechanism is welded on the outer wall of the bottom of the base, a calibration mechanism is arranged on the top of the telescopic mechanism, the fixing mechanism includes a suction cup connecting rod, a suction cup, a central axis and a fixing seat, the telescopic mechanism includes a first telescopic column, a second telescopic column, a telescopic column base, a second positioning bolt and a first positioning bolt, and the calibration mechanism includes a rotating shaft, a rotating seat, a connecting rod, a calibration platform, a threaded column and a nut. The utility model facilitates the folding of the suction cup connecting rod through the central axis, improves portability, and the suction cup can improve stability when fixed on a horizontal plane. The horizontal plane of the top outer wall of the calibration platform is parallel to the horizontal plane of the top outer wall of the rotating seat, ensuring the accuracy of calibration.

[0004] In the above-mentioned prior art, the suction cup connecting rod is rotatably connected to the fixed seat. Even if the three suction cups are adsorbed on the ground, the base can still shake, and the stability of the base cannot be guaranteed. It is also impossible to achieve rapid horizontal calibration of the camera bracket and respond quickly to changes in the shooting environment. For example, when setting on an uneven ground, each adjustment may require recalibration multiple times, which greatly prolongs the camera preparation time. This inefficient adjustment process is particularly obvious in scenes such as news gathering, live broadcasting, and outdoor photography that require rapid deployment. In view of this, we propose a horizontal calibration structure for a video camera bracket. Utility Model Content
