Description

Technical Field

[0001] The utility model relates to the technical field of channel machine extension plates, in particular to a viewfinder expansion plate for a channel camera. Background Art

[0002] In the field of video production and broadcasting, the channel machine, as the core equipment for transmitting and processing video signals, is crucial for multi-camera shooting and real-time switching on site. Traditional channel machines usually have fixed sizes and shapes, which to a certain extent limits their flexibility and applicability in space-constrained shooting environments. Especially in multi-camera shooting on site, the layout of cameras in different positions requires flexible configuration of the position and angle of the channel machine to obtain the best picture effect and ease of operation.

[0003] However, due to the limitations of their design, existing communication machines are often difficult to adapt to complex and changing field environments, especially in situations where space is small or special angle wiring is required.

[0004] In addition, the fixed structure of traditional channel machines also brings inconvenience to the rapid deployment, adjustment and disassembly of the equipment, affecting the efficient progress of filming. Utility Model Content

[0005] The purpose of the utility model is to provide a viewfinder expansion board for a communication channel camera, so as to solve the problem that the fixed structure of a traditional communication channel machine also brings inconvenience to the rapid deployment, adjustment and disassembly of the equipment, thus affecting the efficient performance of the shooting work.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a viewfinder expansion plate for a channel camera, comprising an extended outer arm, an extended inner arm is slidably arranged inside the extended outer arm, an adjustment knob is arranged on the top surface of the extended outer arm, an adjustment bolt is slidably arranged on the bottom surface of the extended inner arm, the threaded end of the adjustment bolt passes through the extended inner arm and extends to the top surface of the extended outer arm, the adjustment knob is connected to the threaded end of the adjustment bolt, and one end of the extended outer arm is flipped to be provided with a connecting fixed arm.

[0007] Preferably, one end of the connecting and fixing arm is detachably connected to a locking clamp, an outer wall of the locking clamp is detachably connected to one end of the extended outer arm, a locking knob is inserted on the locking clamp, the threaded end of the locking knob passes through the locking clamp and is threadedly connected to one end of the connecting and fixing arm.

[0008] Preferably, two second fixing bolts are inserted through the locking clamp, and the threaded ends of the two second fixing bolts are connected to one end of the connecting fixing arm.

[0009] Preferably, a rotating shaft is rotatably arranged inside the locking clamp, a first fixing bolt is inserted through the rotating shaft, and a threaded end of the first fixing bolt is connected to one end of the extended outer arm.

[0010] Preferably, a fixing knob is provided on the top surface of the other end of the connecting fixing arm, a locking block is provided on the bottom surface of the other end of the connecting fixing arm, and the threaded end on the fixing knob passes through the connecting fixing arm and is threadedly connected to the locking block.

[0011] Preferably, a leveling knob is threadedly connected to the connecting and fixing arm.

[0012] Compared with the prior art, the viewfinder expansion board for the channel camera using the above technical solution has the following beneficial effects:

[0013] 1. During use, the user can adjust the relative position between the extended inner arm and the extended outer arm by sliding the extended inner arm according to the specific requirements of the shooting scene, thereby achieving the purpose of sliding to extend the distance. This allows the channel machine to flexibly adapt to shooting environments of different sizes and shapes, especially when space is limited. The adjustability of the extended inner arm and the extended outer arm ensures the practicality of the equipment and the optimization of the layout. When the length adjustment is completed, the user can fix the extended inner arm and the extended outer arm by rotating the adjustment knob. At this time, the threaded end of the adjustment bolt extends toward the inside of the adjustment knob, thereby accurately controlling the position of the extended inner arm relative to the extended outer arm, improving the accuracy after adjustment, and ensuring the stability of the channel machine and the picture quality during shooting;

[0014] 2. During use, the user can rotate the extended outer arm. By turning over the extended outer arm, the length of the connecting fixed arm can be increased. By rotating the locking knob, the locking clamp plate is deformed and cooperates with the rotating shaft to lock the extended outer arm after it is unfolded, ensuring that during the shooting process, even in a complex or unstable on-site environment, the channel machine can maintain a stable position and angle to avoid affecting the shooting effect due to the movement of the equipment;

[0015] 3. During use, the user can adjust the front and rear distance between the connecting fixed arm and the main device by coordinating the fixing knob with the locking block and the limiter on the connecting fixed arm. At the same time, the leveling knob can also be used to adjust the horizontal state of the channel machine to ensure the balance of the equipment, further ensuring the smoothness of the shooting process and the stability of the picture.
