The hole 2 includes a No. 1 threaded hole 201 arranged at the center of the upper part of the speaker body 1, and the No. 1 threaded hole 201 is used for hoisting when the speaker body 1 is provided with a fixed installation. The No. 2 threaded hole 202 is arranged on the outer wall of the speaker body 1, and the No. 2 threaded hole 202 can be used for mobile applications, providing the speaker body 1 with easy deployment in fixed installation and mobile applications. The rectangular holes 203 arranged on both sides of the outer wall of the speaker body 1 reserve space for the hands, which is convenient for workers to accommodate the hand position. The metal handle 3 bolted to the inner side of the rectangular hole 203 can drive the speaker body 1 to be lifted by the worker holding the metal handle 3, thereby driving the speaker body 1 to move in a small range.

[0030] The connecting mechanism 4 is arranged inside the rectangular hole 203, and multiple groups of speaker bodies 1 can be connected in series through the connecting mechanism 4 through a long rod outside, so that two workers can quickly complete the transportation of the speaker body 1. The connecting fixing plate 401 is bolted to the inside of the rectangular hole 203, and the connecting fixing plate 401 can be connected to the speaker body 1, so as to provide stability of the structure on one side during connection. The mounting fixing plates 402 are welded at both ends of one side of the connecting fixing plate 401, and the mounting fixing plates 402 are connected to the connecting fixing plates 401, which can play a role in structural stability, and the mounting fixing plates 402 can provide internal structural stability for connection. The connecting shafts 403 welded on the inner sides of the two groups of mounting fixing plates 402 can The outer structure can be provided with a stable angle change inside the mounting fixing plate 402, a connecting block 404 is rotatably connected to the connecting shaft 403, and the connecting block 404 can drive the structure connected on one side to rotate stably during the rotation, and through the hole opened inside the connecting block 404, the internal structure can be provided with rotation, and the limiting rotating shaft 405 rotatably connected to the inside of the connecting block 404 can be stably rotated inside the connecting block 404, and a positioning connecting plate 406 is welded to the bottom of the limiting rotating shaft 405, and a through hole is opened inside the positioning connecting plate 406, and the positioning connecting plate 406 can be inserted into the interior by workers through a long rod from the outside, so that multiple groups of speaker bodies 1 can be connected in series.

[0031] When multiple groups of speaker bodies 1 need to be transported in series, since the positioning connecting plate 406 is rotatably connected to the inside of the connecting block 404 through the limiting rotating shaft 405, and the connecting block 404 is rotated inside the mounting fixing plate 402 through the connecting shaft 403, the connecting block 404 is rotated from a vertical state to a horizontal state, and then the horizontal positioning connecting plate 406 is rotated from a horizontal state to a vertical state. At this time, the worker can complete the connection of multiple groups of speaker bodies 1 in series by inserting a long rod into the inside of the positioning connecting plate 406. When the speaker body 1 is moved to the specified position, the position can be fine-tuned by lifting and holding the metal handles 3 on both sides, and then the No. 1 threaded hole 201 and the No. 2 threaded hole 202 can be used as lifting points to fix the speaker body 1.

[0032] Example 2

[0033] See also Figure 1-Figure 4 , the utility model provides a technical solution: a compact mobile speaker, comprising: a limiting mechanism 5;

[0034] The compact mobile speaker also includes a limiting mechanism 5, which can keep the connecting mechanisms 4 on both sides of the speaker body 1 in place when not in use, thereby preventing the connecting mechanisms 4 from shaking.

[0035] The limiting mechanism 5 includes a No. 1 fixing block 501 welded on one side of the inner wall of the rectangular hole 203, and a groove is provided on the top of the No. 1 fixing block 501. The No. 1 fixing block 501 can provide a stable connection for the internal structure and can ensure that the internal structure will not deviate during displacement. The connecting rod 502 welded inside the No. 1 fixing block 501 can provide a stable rotation of the structure on the rod, thereby achieving an angle change. The limiting plate 503 connected to the connecting rod 502 is rotated. After the limiting plate 503 is rotated, it can limit the connection mechanism 4 on one side to prevent the connection mechanism 4 from shaking.

[0036] The second fixing block 504 is welded on the other side of the inner wall of the rectangular hole 203, and a groove is opened on the top of the second fixing block 504. The second fixing block 504 can limit one end of the limiting plate 503, so as to stably position one end of the limiting plate 503, and a non-slip rubber pad is pasted inside the groove of the second fixing block 504, and the inner limiting plate 503 can be fixed by the non-slip rubber pad.

[0037] By moving the limit plate 503 on the connecting rod 502 inside the No. 1 fixed block 501, the limit plate 503 rotates on the connecting rod 502, thereby changing the angle. At this time, one end of the limit plate 503 is no longer engaged in the inside of the No. 2 fixed block 504. When the limit plate 503 rotates from a horizontal state to a vertical state, the limit plate 503 can be unlocked.

[0038] The implementation principle of a compact mobile speaker of the present application is:

[0039] First, by moving the limit plate 503 on the connecting rod 502 inside the No. 1 fixed block 501, the limit plate 503 rotates on the connecting rod 502, thereby changing the angle. At this time, one end of the limit plate 503 is no longer engaged in the inside of the No. 2 fixed block 504. When the limit plate 503 rotates from a horizontal state to a vertical state, the limit plate 503 can be unlocked.

[0040] Secondly, when it is necessary to transport multiple groups of speaker bodies 1 in series, since the positioning connecting plate 406 is rotatably connected to the inside of the connecting block 404 through the limiting shaft 405, and the connecting block 404 is rotated inside the mounting fixing plate 402 through the connecting shaft 403, the connecting block 404 is rotated from a vertical state to a horizontal state, and then the horizontal positioning connecting plate 406 is rotated from a horizontal state to a vertical state. At this time, the worker can complete the connection of multiple groups of speaker bodies 1 in series by inserting a long rod into the inside of the positioning connecting plate 406.

[0041] Finally, when the speaker body 1 is moved to the specified position, the position can be fine-tuned by holding the metal handles 3 on both sides, and then the No. 1 threaded hole 201 and the No. 2 threaded hole 202 can be used as lifting points to fix the speaker body 1.

[0042] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
