Description

Technical Field

[0001] The utility model belongs to the technical field of film and television shooting devices, and in particular relates to a machine device for efficient sound collection and photography. 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 CN217721430U discloses a sound source collection device for filming, which belongs to the technical field of filming devices. The sound source collection device for filming includes: a concave movable frame, a plurality of weight-bearing plates are fixedly connected to one side outer wall of the concave movable frame; and an adjustment component, the adjustment component includes a mounting frame, a No. 1 threaded rod, a movable block, a movable plate, two electric telescopic rod bodies, a fixed plate and a microphone body, the mounting frame is fixedly connected to one side outer wall of the concave movable frame, one side outer wall of the mounting frame is provided with a through hole, the No. 1 threaded rod is rotatably connected between the inner walls of the mounting frame, the movable block is movably sleeved on the outer wall of the No. 1 threaded rod, the movable plate is fixedly connected to one side outer wall of the movable block, and the movable plate and the through hole cooperate, the two electric telescopic rod bodies are both installed on one side outer wall of the movable plate, the fixed plate is fixedly connected between the output ends of the two electric telescopic rod bodies, and the microphone body is installed inside the fixed plate.

[0004] Due to the length of the long pole and the quality of the collection equipment, it is rather difficult to lift the long pole and operate it, and it is also tiring for the staff to lift the long pole for a long time. At the same time, the microphone cannot appear in the shooting scene, which makes it difficult for the staff to collect sound sources. In the above-mentioned document, the electric telescopic pole body drives the fixed plate to move along the convex slide rail, thereby driving the position of the microphone body to change, and the staff does not need to hold the long pole for a long time to perform collection operations. However, the size of the concave movable frame used to support the adjustment component is fixed, and it is not convenient to store and load it after the shooting is completed. At the same time, it is necessary to manually rotate the No. 2 threaded rod to drive the contact circular plate to descend to keep the concave movable frame stable, which is rather troublesome.

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

[0006] In view of the problems in the related technology, the utility model proposes a highly efficient sound acquisition and photography machine to overcome the above technical problems existing in the existing related technology.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0010] Furthermore, the support assembly includes a first screw, which is fixedly connected to the second linkage disk, the outer surface of the first screw is threadedly connected to a sliding column, the bottom of the bracket is fixedly connected to a fixed column, the sliding column is slidably connected inside the fixed column, and the bottom of the sliding column is fixedly connected to a support plate.

[0011] Furthermore, the lifting assembly includes a second screw, which is fixedly connected to the outer surface of the double pulley, the outer surface of the second screw is threadedly connected to a first square column, the outer surface of the first square column is slidably connected to a second square column, the second square column is fixedly connected to the bracket, and the top of the first square column is fixedly connected to the folding frame.

[0013] Furthermore, a limiting plate is fixedly connected inside the second square column.

[0014] Furthermore, a pulley is fixedly mounted on the bottom of the bracket.

[0015] The utility model has the following beneficial effects:

[0016] The utility model connects a linkage component, a support component and a lifting component. A motor drives the linkage component to rotate, and the linkage component drives the support component and the lifting component to move simultaneously. When the support component contacts the ground, the linkage component starts to separate during the rotation process and no longer drives the support component, so that the support component remains stationary while the lifting component continues to move. The lifting component can change the height of the folding frame and the radio microphone, which is convenient for storing and loading them. At the same time, the support component and the lifting component can move simultaneously, thereby improving efficiency and being more convenient to use.

[0017] The utility model connects the first linkage disk and the second linkage disk, and the second linkage disk stops rotating after the support plate contacts the ground. At this time, the ball on the first linkage disk is squeezed by the groove on the second linkage disk during rotation, and the ball compresses the telescopic rod and begins to retract. At this time, the first linkage disk no longer drives the second linkage disk through the ball, so that the second linkage disk and the support plate can stop moving. At the same time, it does not affect the rotation of the first linkage disk and the double belt pulley. The double belt pulley can continue to drive the second screw to rotate to adjust the height of the folding frame, so that the height adjustment of the folding frame and the descending movement of the support plate can be carried out synchronously and can be separated at the same time, which is convenient for use by the staff.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] See also Figure 1-Figure 7 As shown, the utility model is a machine device for efficient sound collection and photography, including a bracket 1, a motor 2 is fixedly connected to the inside of the bracket 1, a linkage assembly 3 and a lifting assembly 5 are fixedly connected to the output shaft of the motor 2, a support assembly 4 is arranged at the bottom of the bracket 1, a folding frame 6 is fixedly connected to the top of the lifting assembly 5, a sliding assembly 7 is slidably connected to the outer surface of the folding frame 6, a radio microphone 8 is fixedly installed on the outer surface of the sliding assembly 7, and the motor 2 drives the support assembly 4 to slide through the linkage assembly 3.

[0032] After the bracket 1 is pushed to drive the motor 2, the folding frame 6 and the radio microphone 8 to move to the desired position, the motor 2 is started, and the motor 2 drives the linkage component 3 to rotate. The linkage component 3 simultaneously drives the lifting component 5 and the support component 4. The lifting component 5 drives the folding frame 6 and the radio microphone 8 to move upward, and the support component 4 moves downward to contact the ground and support the bracket 1. When the support component 4 contacts the ground, the linkage component 3 that drives the support component 4 begins to overload and slip, so that the support component 4 no longer moves without affecting the upward movement of the lifting component 5 and the folding frame 6.

[0033] The utility model connects the linkage component 3, the support component 4 and the lifting component 5. The motor 2 drives the linkage component 3 to rotate, and the linkage component 3 drives the support component 4 and the lifting component 5 to move at the same time. When the support component 4 contacts the ground, the linkage component 3 starts to separate during the rotation process and no longer drives the support component 4, so that the support component 4 remains stationary while the lifting component 5 continues to move. The lifting component 5 can change the height of the folding frame 6 and the radio microphone 8, which is convenient for storing and loading them. At the same time, the support component 4 and the lifting component 5 can move at the same time, which improves efficiency and is more convenient to use.

[0034] In one embodiment, for the above-mentioned linkage component 3, the linkage component 3 includes a double pulley 301, the double pulley 301 is fixedly connected to the output shaft of the motor 2, the outer surface of the double pulley 301 is provided with a belt 302, the double pulley 301 is connected to a single pulley 303 through the belt 302, the outer surface of the single pulley 303 is fixedly connected to a rotating shaft 304, the outer surface of the rotating shaft 304 is fixedly connected to a first linkage disk 305, the interior of the first linkage disk 305 is fixedly connected to a telescopic rod 306, the movable end of the telescopic rod 306 is fixedly connected to a ball 307, the bottom of the first linkage disk 305 is provided with a second linkage disk 308, the outer surface of the second linkage disk 308 is provided with a groove 309, and the ball 307 is plugged into the groove 309.

[0035] Start the motor 2, which drives the double pulley 301 to rotate. The double pulley 301 drives the single pulley 303 to rotate synchronously through the belt 302. The single pulley 303 drives the rotating shaft 304 and the first linkage disk 305 to rotate. The first linkage disk 305 drives the second linkage disk 308 to rotate through the connection between the ball 307 and the groove 309. If it encounters a large resistance during the rotation, the second linkage disk 308 remains stationary. The ball 307 on the first linkage disk 305 is squeezed by the edge of the groove 309 on the second linkage disk 308 during rotation, so that the ball 307 compresses the telescopic rod 306 and retracts it into the first linkage disk 305, so that the first linkage disk 305 continues to rotate while the second linkage disk 308 remains stationary.

[0036] In one embodiment, for the above-mentioned support assembly 4, the support assembly 4 includes a first screw 401, the first screw 401 is fixedly connected to the second linkage disk 308, the outer surface of the first screw 401 is threadedly connected with a sliding column 402, the bottom of the bracket 1 is fixedly connected with a fixed column 403, the sliding column 402 is slidably connected inside the fixed column 403, and the bottom of the sliding column 402 is fixedly connected with a support plate 404.

[0037] The second linkage disk 308 drives the first screw 401 to rotate, and the first screw 401 drives the sliding column 402 installed in the fixed column 403 to slide, and the sliding column 402 drives the support plate 404 to move downward. After the support plate 404 contacts the ground, the resistance increases. At this time, the support plate 404 and the sliding column 402 cannot move downward, and the first screw 401 in the sliding column 402 stops rotating, and the second linkage disk 308 on the first screw 401 is separated from the first linkage disk 305. Through the connection between the sliding column 402 and the fixed column 403, the fixed column 403 can prevent the sliding column 402 from rotating with the first screw 401, and can also guide and limit the movement of the sliding column 402.

[0038] In one embodiment, for the above-mentioned lifting assembly 5, the lifting assembly 5 includes a second screw 501, the second screw 501 is fixedly connected to the outer surface of the double pulley 301, the outer surface of the second screw 501 is threadedly connected to the first square column 502, the outer surface of the first square column 502 is slidably connected to the second square column 503, the second square column 503 is fixedly connected to the bracket 1, and the top of the first square column 502 is fixedly connected to the folding frame 6.

[0039] The double pulley 301 drives the second screw 501 to rotate, and the second screw 501 drives the first square column 502 to slide along the second square column 503. The first square column 502 can drive the folding frame 6 and the radio microphone 8 to adjust the height. After the first linkage disk 305 is separated from the second linkage disk 308, the double pulley 301 still keeps rotating, so that the first square column 502 can continue to drive the folding frame 6 to move.

[0040] In one embodiment, for the above-mentioned sliding assembly 7, the sliding assembly 7 includes a sliding trolley 701, the sliding trolley 701 is slidably connected to the outer surface of the folding frame 6, the outer surface of the sliding trolley 701 is fixedly connected with a square plate 702, the outer surface of the square plate 702 is fixedly connected with an electric push rod 703, the movable end of the electric push rod 703 is fixedly connected with a mounting seat 704, and the radio microphone 8 is fixedly installed inside the mounting seat 704.

[0041] Start the sliding trolley 701, and the sliding trolley 701 drives the square plate 702 and the radio microphone 8 to move along the folding frame 6, so as to change the horizontal position of the radio microphone 8. Start the electric push rod 703 to drive the mounting base 704 and the radio microphone 8 to move up and down, so as to change the height position of the radio microphone 8. After use, the folding frame 6 can be folded in half and matched with the first square column 502 and the second square column 503 to reduce the floor space and facilitate storage and transportation.

[0042] In one embodiment, for the second square column 503 , the interior of the second square column 503 is fixedly connected to a limiting plate 9 .

[0043] In one embodiment, for the above-mentioned bracket 1 , a pulley 10 is fixedly installed at the bottom of the bracket 1 .

[0044] The limiting plate 9 can limit the movement of the first square column 502 to prevent the first square column 502 from excessively descending and contacting the double pulley 301. The pulley 10 at the bottom of the bracket 1 can reduce the friction during its movement, making it easier to adjust the position of the bracket 1.

[0045] Through the above technical scheme, 1. through the connection of the linkage component 3, the support component 4 and the lifting component 5, the motor 2 drives the linkage component 3 to rotate, and the linkage component 3 drives the support component 4 and the lifting component 5 to move at the same time. When the support component 4 contacts the ground, the linkage component 3 begins to separate during the rotation process and no longer drives the support component 4, so that the support component 4 remains stationary while the lifting component 5 continues to move. The lifting component 5 can change the height of the folding frame 6 and the radio microphone 8, which is convenient for their storage and loading. At the same time, the support component 4 and the lifting component 5 can move at the same time, which improves efficiency and is more convenient to use. 2. Through the connection between the first linkage disk 305 and the second linkage disk 308, the second linkage disk 308 stops rotating after the support plate 404 contacts the ground. At this time, the ball 307 on the first linkage disk 305 is squeezed by the groove 309 on the second linkage disk 308 during rotation, and the ball 307 compresses the telescopic rod 306 and begins to retract. At this time, the first linkage disk 305 no longer drives the second linkage disk 308 through the ball 307, so that the second linkage disk 308 and the support plate 404 can stop moving. At the same time, it does not affect the rotation of the first linkage disk 305 and the double pulley 301. The double pulley 301 can continue to drive the second screw 501 to rotate to adjust the height of the folding frame 6, so that the height adjustment of the folding frame 6 and the descending movement of the support plate 404 can be carried out synchronously and can be separated. Operation is convenient for the staff.
