Description

Technical Field

[0001] This utility model relates to the field of broadcasting equipment, and in particular to a multi-angle broadcasting device. Background Technology

[0002] Broadcasting refers to a news dissemination tool that transmits sound through radio waves or wires. Broadcasting that transmits programs through radio waves is called wireless broadcasting, while broadcasting that transmits programs through wires is called wired broadcasting. The advantages of broadcasting are its wide reach, rapid dissemination, diverse functions, and strong appeal. Broadcasting systems used in public places are generally fixed and installed on the surface of concrete columns or other high places on other structures.

[0003] The loudspeakers are usually bolted to the top of concrete columns, and their horn openings are fixed in direction, emitting sound waves in only one direction. The amplification effect of the broadcast will decrease when pedestrians are in different positions, reducing the practicality of the device. In addition, since the bolts for mounting the loudspeakers are usually exposed, sunlight and rain will cause the bolts to rust and corrode, making it difficult to remove the bolts for repair or replacement of the loudspeakers later. Moreover, the bolts need to be removed with tools. Due to the high installation position of the loudspeakers, it is dangerous for personnel to operate them at height. Utility Model Content

[0004] The purpose of this invention is to solve the problems of fixed orientation of the above-mentioned loudspeaker, which can only emit sound waves in one direction. When pedestrians are in different positions, the sound amplification effect of the broadcast will decrease. In addition, since the bolts for mounting the loudspeaker are usually exposed, sunlight and rain will cause the bolts to rust and corrode, making it difficult to remove the bolts for maintenance and replacement of the loudspeaker later. Therefore, a multi-angle broadcasting device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-angle broadcasting device, comprising a column, a mounting frame, and a speaker body. The column has four mounting slots on one side of its outer wall. A throttle handle is located on the top of the column. Fixed shafts are fixedly connected to both ends of the speaker body's outer wall. One end of each fixed shaft is movably connected to the inner wall of the mounting frame.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figures 1-5As shown, this utility model provides a technical solution: a multi-angle broadcasting device, including a column 1, a mounting bracket 2, and a speaker body 3. Four mounting slots 101 are provided on one side of the outer wall of the column 1. A handle 11 is provided on the top of the column 1. Fixed shafts 31 are fixedly connected to both ends of the outer wall of the speaker body 3. One end of the surface of the fixed shaft 31 is movably connected to the inner wall of the mounting bracket 2. Two fixing blocks 21 are fixedly connected to one side of the outer wall of the mounting bracket 2. A movable rod 22 is movably installed inside the fixing blocks 21. A connecting plate 4 is fixedly connected to one side of the outer wall of the mounting bracket 2. A connecting block 41 is fixedly connected to one side of the outer wall of the connecting plate 4. A drive motor 5 is fixedly installed on the bottom of the other side of the plate 4. The inside of the column 1 is a hollow structure with a through hole. One end of each of the two fixed shafts 31 is fixedly connected to a pulley 32. A belt 33 is movably installed on the surface of the pulley 32. Both ends of the movable rod 22 are fixedly connected to pulleys 23. A helical gear 24 is fixedly installed on the surface of the movable rod 22. The outer wall of the pulley 23 is movably connected to one end of the inner side of the belt 33. A connecting rod 51 is fixedly installed on the top of the drive motor 5. A helical gear 52 is fixedly connected to the top of the connecting rod 51. One side of the helical gear 52 meshes with one side of the helical gear 24.

[0025] In this embodiment, the drive motor 5 drives the connecting rod 51 and the second helical gear 52 to rotate. The second helical gear 52 meshes with the first helical gear 24, causing it to drive the movable rod 22 to rotate. The second pulley 23 is connected to the first pulley 32 through the belt 33, causing the first pulley 32 to drive the fixed shaft 31 to rotate. At this time, the speaker body 3 rotates around the fixed shaft 31 as the center, which facilitates the adjustment of the angle of the speaker body 3.

[0026] Example 2

[0027] like Figures 1-5 As shown, a screw 12 is fixedly connected to the bottom of the throttle 11. The bottom of the screw 12 is movably connected to the inner wall of the column 1. A movable block 13 is threadedly connected to the surface of the screw 12. The side of the movable block 13 is tightly fitted to the inner wall of the column 1. A limit block 14 is fixedly installed inside the through hole of the column 1. A slide rod 6 is provided inside the through hole of the column 1. A ring 61 is fixedly connected to the surface of the slide rod 6. A spring 62 is movably connected to one side of the ring 61. The other end of the spring 62 is tightly fitted to one side of the limit block 14. One end of the slide rod 6 is in an inclined state. The shape of one end of the slide rod 6 matches one end of the movable block 13. One side of the connecting block 41 has a hollow structure. The size of the connecting block 41 is the same as the size of the mounting groove 101.

[0028] In this embodiment, the connecting block 41 on one side of the connecting plate 4 is placed into the mounting groove 101. Then, by rotating the handle 11, the screw 12 is rotated. The screw 12 rotates and the movable block 13 on its surface moves up and down. When the movable block 13 moves downward, one side of it presses against one end of the slide rod 6, causing the other end of the slide rod 6 to move into the mounting groove 101 and limit the connecting block 41. At the same time as the slide rod 6 moves, the spring 62 on its surface is compressed and contracted by the ring 61. At this time, the connecting block 41 cannot be removed from the mounting groove 101, thus completing the installation of the speaker body 3. By reversing the handle 11, the movable block 13 is moved upward, and the spring 62 rebounds to reset the slide rod 6. At this time, one end of the slide rod 6 is disengaged from the connecting block 41, and the connecting block 41 can be removed from the mounting groove 101, thus completing the disassembly of the speaker body 3.

[0029] The working principle of this embodiment is as follows: The drive motor 5 drives the connecting rod 51 and the second helical gear 52 to rotate. The second helical gear 52 drives the movable rod 22 and the second pulley 23 to rotate. The belt 33 connects the pulley 32 to drive the fixed shaft 31 to rotate. At this time, the speaker body 3 rotates around the fixed shaft 31 as the center, and the angle of the speaker body 3 is adjusted. The connecting block 41 on one side of the connecting plate 4 is placed into the mounting groove 101. Then, by turning the handle 11, the movable block 13 moves on the surface of the screw 12. The movable block 13 moves downward and presses one end of the slide rod 6, so that the other end of the slide rod 6 moves into the mounting groove 101 to limit the connection block 41, thus completing the installation of the speaker body 3. By reversing the handle 11, the movable block 13 moves upward, and the spring 62 rebounds to reset the slide rod 6. At this time, one end of the slide rod 6 disengages from the inside of the connecting block 41, and the connecting block 41 can be taken out from the inside of the mounting groove 101, thus completing the disassembly of the speaker body 3. This allows the staff to install and disassemble the speaker body 3 without the need for tools.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
