Description

Technical Field

[0001] This utility model relates to the field of sound recording equipment technology, and in particular to a sound recording device for film and television production. Background Technology

[0002] Film and television microphones are acoustic devices specifically designed to capture sound information from film and television footage. They can reproduce sound details such as actors' lines and environmental sound effects, providing clear and high-quality audio material for the work. Shotgun microphones are highly directional, capable of accurately capturing sound from specific directions. They are typically mounted on booms or stands and are commonly used for scene sound effects capture and long-distance sound recording. However, this recording process often requires the sound engineer to hold a long boom and hold the microphone suspended in the air, making the operation laborious. Therefore, it is necessary to improve the recording method to reduce the workload of the sound engineer and ensure stable microphone recording. For example, the existing Chinese utility model patent with publication number CN215773486U: a sound recording device for film and television shooting with easy position adjustment. This application uses a push rod to retract and clamp the clamp, which is very convenient. The clamp can be controlled to tighten or loosen by changing the position of the pin in the through hole. However, the overall structure of this application is large. Wheels are set at the bottom to facilitate movement. In film and television shooting locations, due to the many shooting scenes, this application cannot achieve convenient scene transitions. Utility Model Content

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-8 As shown, the present invention provides a sound recording device for film and television production, including a belt 1 and an operating rod 27. A base plate 2 is fixedly connected to one side of the belt 1 via a connecting buckle 13. A rod sleeve 3 is provided on one side of the base plate 2. A connecting plate 4 is fixedly connected to the side of the rod sleeve 3 opposite to the side of the base plate 2. The rod sleeve 3 is movably connected to one side of the base plate 2 via the connecting plate 4. An installation groove 5 is opened in the connecting plate 4. A limiting plate 6 is inserted through the installation groove 5. A U-shaped pull rod 7 is fixedly connected to one side of the limiting plate 6, and the U-shaped pull rod 7 is also inserted through the outside of the rod sleeve 3. Several guide plates 8 are fixedly connected to the side of the rod sleeve 3 opposite to the connecting plate 4. A pressure block 10 is inserted through the rod sleeve 3 located between two guide plates 8. A first push block 11 is also movably connected between two guide plates 8. A second push block 12 is also movably connected between two guide plates 8 near the U-shaped pull rod 7. One end of the operating rod 27 is inserted through the rod sleeve 3.

[0017] like Figure 4 As shown, a number of slots 14 are provided on one side of the substrate 2. The slots 14 are arranged in a ring around the center point of one side of the substrate 2, which can be used with the limiting plate 6 to limit the axial movement of the connecting plate 4. A limiting ring 15 is fixedly connected to one side of the substrate 2 near the slots 14 to realize the rotational connection function between the substrate 2 and the connecting plate 4.

[0018] like Figures 3-8As shown, the connecting plate 4 is rotatably connected between the base plate 2 and the limiting ring 15 via the outer convex ring. Two guide tubes 16 are fixedly connected between the connecting plate 4 and the rod sleeve 3. The two ends of the U-shaped pull rod 7 are respectively inserted into the corresponding guide tubes 16, thereby providing guidance for the movement of the U-shaped pull rod 7 outside the rod sleeve 3. Several locking blocks 17 are fixedly connected to one side of the limiting plate 6. The locking blocks 17 are arranged circumferentially around the outer contour of the limiting plate 6. A push groove 18 is opened on one side of the U-shaped pull rod 7. A fixing block 19 is inserted into one side of the limiting plate 6 and the mounting groove 5 to provide support force for the limiting plate 6, so that the limiting plate... The several locking blocks 17 of the 6-clothes moth can be respectively locked into the corresponding locking slots 14, which can cooperate with the U-shaped pull rod 7 to restrict the axial movement of the sleeve 3 and support the operating rod 27. The guide plate 8 has a sliding groove 22. A fixing block 19 is fixedly connected between two adjacent guide plates 8. A guide shaft 20 is fixedly connected to one side of the fixing block 19. A second compression spring 21 is fitted on the outside of the guide shaft 20. The guide shaft 20 is used to provide a guide path for the extension and retraction of the guide shaft 20, thereby providing a reset capability for the first push block 11 through the second compression spring 21. One side of the first push block 11 is provided with a corresponding side to the pressure block 10. On the slope, the top and bottom of the first push block 11 are fixedly connected to the first slider 23, which is slidably connected in the corresponding groove 22. The side of the first push block 11 away from the rod sleeve 3 is fixedly connected to the first operating block 25, so that the first push block 11 can be in its normal position on the side of the corresponding pressure block 10 under the action of the second compression spring 21. This causes the side of the pressure block 10 away from the first push block 11 to press against the outside of the operating rod 27 inserted in the rod sleeve 3 with a certain pressure. The two sets of symmetrically arranged pressure blocks 10 and the first push block 11 realize the positioning of the operating rod 27 in the rod sleeve 3. The second push block 12 is fixedly connected to the top and bottom of the second slider 24. The second push block 12 is fixedly connected to the side opposite to the rod sleeve 3. The side of the second push block 12 opposite to the second operating block 26 is provided with a slope to cooperate with the push groove 18 on one side of the U-shaped pull rod 7. This allows the U-shaped pull rod 7 to be pushed and the limiting plate 6 to be completely retracted into the mounting groove 5, so that the locking block 17 is disengaged from the corresponding locking groove 14. The operating rod 27 can be used to rotate the rod sleeve 3 and the connecting plate 4 to adjust the operating angle of the operating rod 27. One end of the operating rod 27 is fixedly connected to a microphone 28.

[0019] It should be noted that this utility model is a sound recording device for film and television production. In use, the entire device is first fixed to the sound engineer's body using the belt 1, and the connecting buckle 13 ensures the base plate 2 is securely fitted to the body. Then, the operator holds the operating lever 27 and adjusts the sound-receiving position of the microphone 28 according to the operator's movements. Before use, when adjusting the installation position of the operating lever 27 within the lever sleeve 3, simply pinch the two first operating blocks 25 together with one hand. The first operating blocks 25 then drive the first push block 11 to move between the corresponding two guide plates 8, while the first slider 23 moves along the guide plates... The slide groove 22 inside 8 moves, causing the sink groove inside the first push block 11 to move on the corresponding guide shaft 20 and compress the second compression spring 21. As a result, the slope on one side of the first push block 11 separates from the pressure block 10 and no longer applies pressure to the pressure block 10. At this time, the operating rod 27 can be manually pushed and pulled to move inside the rod sleeve 3. After the adjustment is completed, the two first operating blocks 25 can be released. The second compression spring 21 pushes the first push block 11 to reset through the guide shaft 20. The pressure block 10 presses tightly against the outside of the operating rod 27 under the reverse force, thereby fixing the installation position of the operating rod 27 inside the rod sleeve 3. When adjusting the operating angle of the operating lever 27, the second operating block 26 can be pushed with one hand to move the second push block 12 between the corresponding two guide plates 8, while the second slider 24 moves along the corresponding slide groove 22. The slope of the second push block 12 is embedded in the push groove 18 of the U-shaped pull rod 7, pushing the U-shaped pull rod 7 to move away from the base plate 2 along the guide tube 16, thereby pulling the limiting plate 6 to retract into the mounting groove 5 of the connecting plate 4. The locking block 17 on the limiting plate 6 disengages from the locking groove 14 of the base plate 2. At this time, the operating lever 27 can be rotated to drive the rod sleeve 3 and the connecting plate 4 to rotate around the convex ring between the base plate 2 and the limiting ring 15. After adjusting to a suitable sound reception angle, the second operating block 26 is released, and the limiting plate 6 is pushed out of the mounting groove 5 by the rebound force of the first compression spring 9, so that several locking blocks 17 on one side of the limiting plate 6 are locked into the corresponding locking groove 14, and the axial movement of the rod sleeve 3 is limited again, thereby completing the angle locking of the operating lever 27.
