Description

Technical Field

[0001] The utility model relates to the technical field of camera brackets, in particular to a universal joint bracket for a video camera. Background Art

[0002] Video cameras are key tools for capturing and recording images and videos. They are widely used in filmmaking, television broadcasting, news reporting, sports events, personal entertainment and many other fields. In order to improve video quality, it is crucial to maintain the stability of the picture. As an important auxiliary equipment to support and stabilize the camera, the video camera gimbal bracket enables the camera to freely adjust the angle in three-dimensional space. Through its adjustable joints, it effectively helps the cameraman maintain the stability and smoothness of the picture under various shooting conditions.

[0003] The patent with publication number CN213479623U discloses a universal joint bracket for fixing and adjusting the angle of a camera, comprising a first bracket, the first bracket is provided with a rotating shaft, the first bracket is rotatably connected to the rotating shaft, the rotating shaft is provided with a second bracket, the second bracket is rotatably connected to the rotating shaft, the first bracket is fixedly connected to a motor, the motor is fixedly connected to a turntable, the turntable is fixedly connected to a camera, the turntable is rotatably connected to the top of the first bracket, the first bracket is provided with a first groove, the second bracket is provided with a second groove, the first groove is provided with a limit rod, a fourth groove is penetrated on the right side of the limit rod, the limit rod sequentially penetrates the first groove, the second groove, and the limit mechanism and extends to the inside of the limit mechanism, the limit mechanism is fixedly connected to the top of the inner wall on the left side of the inner cavity of the second bracket, on the one hand, the operation is simple, and the operation can be completed by pulling the pull rod and squeezing the limit rod, and on the other hand, it effectively prevents the first bracket from rotating automatically.

[0004] The above-mentioned prior art realizes the horizontal angle adjustment of the camera, and is realized by rotating the turntable driven by a motor, but it is relatively complicated and limited when adjusting the pitch angle of the camera. The staff must disassemble the limit rod and reposition the limit rod through an external plug rod to achieve the fixation of the relative position of the first bracket and the second bracket. This pitch angle adjustment method is not only cumbersome to operate, but also because the positions of the first groove and the second groove must correspond, the pitch angle adjustment range of the camera is limited and can only be adjusted to a few fixed angles. This greatly reduces the flexibility and convenience of operation in practical applications. In view of this, we propose a video camera universal joint bracket. Utility Model Content
