Technical Field

[0001] The utility model belongs to the technical field of sound source collection, and in particular relates to a sound source collection device. Background Art

[0002] The sound source collection device is mainly used in the shooting process of film and television works. Usually, the staff holds a long pole with a microphone connected to the upper end of the pole, and places the microphone above the upper limit of the camera shooting screen, so that the microphone will not be photographed in the filmed film and television works, and can also collect clearer sound source information.

[0003] Chinese patent CN218914250U discloses a sound source collection device for filming, which belongs to the technical field of sound source collection. The sound source collection device for filming includes a base, a fixed plate is provided on the base through a lifting device, a mounting plate is provided on one side of the fixed plate, a fixed sleeve is provided on the other side, and the mounting plate is fixedly connected to the side wall of the fixed sleeve, a winding assembly is provided on the mounting plate, an extension rod is provided inside the fixed sleeve through a pushing mechanism, a sound collector is provided at the end of the extension rod through a rotating assembly, and the pushing mechanism is connected to the rotating assembly through a connecting guide assembly.

[0004] The staff has to hold the high pole for a long time, which is labor-intensive and the high pole is easy to fall out of their hands, causing safety hazards. In the above document, the height of the sound collector can be changed by a lifting device, and the position of the sound collector can be changed by moving the base. The staff does not need to hold the sound collector, but the sound collector is rotatably connected to the extension rod. When the extension rod is retracted, the hanging rope will become loose, causing the sound collector to suddenly rotate downward, which can easily damage the sound collector.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0031] First, the adjusting component 1 changes the position of the sound tube 6, and then the pushing component 7 is rotated to release the connecting belt 4 to change the angle of the sound tube 6, and then the telescopic component 8 on the adjusting component 1 is plugged into the limiting component 9 to keep the angle between the limiting component 9, the sound tube 6 and the adjusting component 1 fixed. When the adjusting component 1 drives the sound tube 6 to retract, the connecting belt 4 on the sound tube 6 is retracted by the winding spring 5, and at the same time, the angle between the sound tube 6 and the adjusting component 1 is fixed, which can prevent the sound tube 6 from falling suddenly and causing it to collide and be damaged.

[0032] The utility model connects the sound tube 6 with the limit assembly 9. When the limit assembly 9 is plugged into the telescopic assembly 8, the angle of the limit assembly 9 is fixed, and then the angle of the sound tube 6 on the limit assembly 9 is fixed synchronously. At this time, the adjustment assembly 1 drives the sound tube 6 to move, and the angle of the sound tube 6 is no longer affected by the connecting belt 4. Even if the connecting belt 4 becomes loose, the sound tube 6 can still maintain a fixed angle, thereby avoiding the situation where the sound tube 6 suddenly falls and causes an impact and causes damage to it.

Starting the second electric push rod 104 can drive the sound tube 6 to move, and can change the position of the sound tube 6 in the horizontal direction, so that the sound tube 6 can better adapt to the different needs of the shooting scene.

[0035] In one embodiment, for the above-mentioned pushing component 7, the pushing component 7 includes a fixed plate 701, the fixed plate 701 is fixedly connected to the rotating plate 105, the internal rotation of the fixed plate 701 is connected to a first rotating shaft 702, the outer surface of the first rotating shaft 702 is fixedly connected to a pushing wheel 703, the end of the first rotating shaft 702 is fixedly connected to a hand wheel 704, and the pushing wheel 703 is engaged with the connecting belt 4.

[0036] Rotate the handwheel 704 clockwise to the right, the handwheel 704 drives the first rotating shaft 702 and the pushing wheel 703 to rotate, the pushing wheel 703 meshes with the connecting belt 4 and pushes the connecting belt 4 to move, at this time the connecting belt 4 extends out from the winding box 3, and the sound tube 6 at the end of the connecting belt 4 starts to rotate downward through the rotational connection between it and the second electric push rod 104, when the handwheel 704 rotates counterclockwise to the left, the connecting belt 4 is retracted, and the connecting belt 4 drives the sound tube 6 to rotate upward, thereby achieving the purpose of changing the angle of the sound tube 6, and it is more flexible to use.

[0037] In one embodiment, for the telescopic assembly 8, the telescopic assembly 8 includes a fixed cylinder 801, which is fixedly connected to the rotating plate 105, and the interior of the fixed cylinder 801 is slidably connected to a round rod 802 and a sliding ring 803, and the outer surface of the sliding ring 803 is fixedly connected to a spring 804.

[0039] Pulling the round rod 802 drives the sliding ring 803 to move to the left, and the sliding ring 803 compresses the spring 804. At the same time, the round rod 802 separates from the limiting groove 903 on the limiting ring 902, releasing the limiting fixation of the limiting ring 902 and the second rotating shaft 901. At this time, the microphone 6 and the second rotating shaft 901 can be rotated to adjust the angle. The round rod 802 is released, and the spring 804 pushes the round ring 803 and the round rod 802 to reset. The round rod 802 is plugged into the limiting groove 903 to limit and fix the microphone 6. At this time, the second baffle 905 on the round rod 802 is in contact with the first baffle 904. When the second electric push rod 104 drives the first baffle 904 to move, it will push the second baffle 905, so that the second baffle 905 and the round rod 802 can move synchronously with the limiting ring 902.

[0042] Pushing the bottom plate 12 to move through the second pulley 13 can drive the microphone 6 to move, and the electric slider 15 slides in the slide groove 14 on the bottom plate 12, so that the electric push rod 15 can provide the first electric push rod 101 with power for lateral movement. The first pulley 10 and the fixing frame 11 support the connecting belt 4 to prevent the connecting belt 4 from shaking during the movement.

[0043] Through the above technical scheme, 1. through the connection between the sound tube 6 and the limit assembly 9, when the limit assembly 9 is plugged into the telescopic assembly 8, the angle of the limit assembly 9 is fixed, and then the angle of the sound tube 6 on the limit assembly 9 is fixed synchronously, at this time, the adjustment assembly 1 drives the sound tube 6 to move, and the angle of the sound tube 6 is no longer affected by the connecting belt 4, even if the connecting belt 4 becomes loose, the sound tube 6 can still maintain a fixed angle, thereby avoiding the situation where the sound tube 6 suddenly falls and causes impact and causes damage to it. 2. Through the connection between the round rod 802 and the limiting groove 903, when the round rod 802 is located in the limiting groove 903, the rotation of the second rotating shaft 901 and the sound tube 6 is blocked by the round rod 802, so that the angle between the sound tube 6 and the second electric push rod 104 remains fixed. At this time, the second electric push rod 104 drives the sound tube 6 to move to the left, and the connecting belt 4 on the sound tube 6 becomes loose. However, due to the blocking effect of the round rod 802, the sound tube 6 can still remain fixed. At the same time, the connecting belt 4 will be wound up by the winding spring 5, thereby preventing the sound tube 6 from suddenly falling and causing impact and causing damage to it.
