[0024] The linkage 85 includes a long rod 850, which is fixed to the surface of the mounting seat 4, and one end of the long rod 850 away from the mounting seat 4 passes through the through hole of the pull plate 81, and one end of the long rod 850 away from the mounting seat 4 is fixed with a fixed plate 851, and a fixed block 852 passes through the long rod 850, and the fixed block 852 is fixedly connected to the long rod 850, and a movable block 853 passes through the long rod 850, and the movable block 853 is slidably connected to the long rod 850, and a spring three 854 is fixed to the end of the movable block 853 away from the fixed block 852, and the end of the spring three 854 away from the movable block 853 is fixed to the surface of the fixed plate 851, and a resisting rod 855 is fixed to the side of the fixed plate 851 close to the long rod 850, and the end of the resisting rod 855 away from the fixed plate 851 conflicts with the end of the movable block 853 away from the fixed block 852. When the side of the limit block 83 away from the inclined surface and the fixed block 852 close to the movable surface When the surface of one side of the movable block 853 conflicts with the fixed block 852, the fixed block 852 is limited by the limit block 83, so that the pull plate 81 and the limit rod 80 are limited. At this time, the personnel puts the base 3 into the groove of the mounting seat 4 and pulls the pull plate 81 again. When the side of the limit block 83 away from the inclined surface conflicts with the side of the movable block 853 away from the fixed block 852, the pull plate 81 drives the limit block 83 and the movable block 853 to move inwardly under the action of the spring 1 82. When the movable block 853 is in contact with the surface of the fixed block 852, the limit block 83 will move along the surface of the movable block 853, thereby releasing the limit of the limit block 83, so that the pull plate 81 drives the limit rod 80 to return to its position. At this time, the limit rod 80 enters the through hole of the base 3, which is convenient for personnel to install. When disassembling, you only need to pull the pull plate 81 again to make the limit rod 80 disengage from the through hole of the base 3, and then you can disassemble it.

[0025] The side of the limit block 83 away from the mounting seat 4 is set in an inclined shape, and when it is resisted, the limit block 83 can enter the sliding groove of the pull plate 81;

[0026] The fixed block 852 and the movable block 853 are both set to be isosceles trapezoids, and the fixed block 852 and the movable block 853 are oriented in opposite directions. When the fixed block 852 and the movable block 853 are fitted together, they can contact the limit of the limit block 83;

[0027] A motor 5 is fixed on the top of the base 3, and a gear 1 6 is passed through the output shaft of the motor 5, and the gear 1 6 is fixedly connected to the output shaft of the motor 5. A gear 2 7 is passed through the rotating rod 2, and the gear 2 7 is fixedly connected to the rotating rod 2, so that the angle of the megaphone body 1 can be adjusted conveniently, and it is convenient to use;

[0028] A through hole is formed on the surface of the base 3, and the shape of the through hole is consistent with the shape of the limiting rod 80;

[0029] The surface of the mounting seat 4 is provided with mounting holes for easy installation.

[0030] When installation is required, the mounting seat 4 is fixed to a certain place of the ship. At this time, the pull plate 81 is pulled outward, which will drive the limit rod 80 to move outward, so that the limit rod 80 is no longer located in the groove of the mounting seat 4. At the same time, when the pull plate 81 is pulled, the limit block 83 will be driven to move synchronously. When the inclined surface of the limit block 83 conflicts with the surface of the fixed block 852, the limit block 83 will enter the slide groove of the pull plate 81. When the side of the limit block 83 away from the inclined surface conflicts with the side surface of the fixed block 852 close to the movable block 853, the fixed block 852 is limited by the limit block 83, so that the pull plate 81 and the limit rod 80 are limited. At this time, the personnel put the base 3 into the groove of the mounting seat 4, and then pull the pull plate 81 again. When the side of the limit block 83 away from the inclined surface conflicts with the side of the movable block 853 away from the fixed block 852, at this time, the spring 82 Under the action of , the pull plate 81 drives the limit block 83 and the movable block 853 to move inward. When the movable block 853 is in contact with the surface of the fixed block 852, the limit block 83 will move along the surface of the movable block 853, thereby releasing the limit on the limit block 83, so that the pull plate 81 drives the limit rod 80 to return to its position. At this time, the limit rod 80 enters the through hole of the base 3, thereby limiting and fixing the base 3, which is convenient for personnel to install. When maintenance is needed, it is only necessary to pull the pull plate 81 outward so that the fixed block 852 limits the limit block 83, so that the limit rod 80 can be separated from the through hole of the base 3, and the personnel can take it out for maintenance. However, when the angle of the loudspeaker body 1 needs to be adjusted, the motor 5 is turned on to rotate the gear 1 6, thereby driving the gear 2 7 to rotate, so that the rotating rod 2 drives the loudspeaker body 1 to rotate, thereby adjusting the angle.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
