Description

Technical Field

[0001] The utility model relates to the technical field of voice broadcasting, in particular to a factory voice broadcasting device. Background Art

[0002] A voice announcement device is a type of speaker widely used in factories. When used in elevators, a user typically presses a call button outside the elevator hall to call the car to their designated destination floor, prompting them to board and exit the elevator. With increasing elevator speeds and improved group control and dispatching systems, many elevators have eliminated landing display screens or retained only base station floor displays. Instead, they use an audio-visual announcement panel to signal the arrival of a call station. When the elevator is about to arrive, a bell sounds, and the direction lights flash or indicate the direction of travel. Some elevators also use voice announcements inside the car to alert passengers. Voice announcement systems in elevators are typically secured with bolts and nuts.

[0003] A Chinese patent discloses an elevator fault voice broadcast device with publication number CN210339982U. The problem it aims to solve is that the existing elevator fault broadcast device cannot broadcast effectively. The application solves this problem very well. However, in the process of installing the voice box, multiple parts need to be assembled, and the process is cumbersome. When the device has problems and is damaged, disassembly and replacement is cumbersome and not convenient, and the efficiency of disassembly and assembly is low. Utility Model Content

The limit block 8 is movably inserted into the inner cavity of the limit slot 9, and the limit block 8 and the limit slot 9 match each other. The top of the voice announcer body 7 is fixedly connected to the handles 10 near the left and right sides. The two handles 10 are provided with a cross bar 11 on the side away from each other. The cross bar 11 is arranged in a curved surface. The cross bar 11 and the top of the handle 10 are flush with each other. The front and rear ends of the cross bar 11 are fixedly connected to the connecting plate 12, and the front and rear sides of the handle 10 are fixedly connected to the fixing plate 1 4. A spring 13 is fixedly connected between the connecting plate 12 and the adjacent fixed plate 14. A through hole is provided on the fixed plate 14. A limit rod 16 is movably passed through the inner cavity of the through hole. One end of the limit rod 16 movably passes through the spring 13 and is fixedly connected to the connecting plate 12. The other end of the limit rod 16 is fixedly connected to the limit plate 15. A plug rod 17 is fixedly connected to the bottom of the connecting plate 12. Two insertion holes 18 are provided on the fixing bar 6. The plug rod 17 and the insertion hole 18 match each other. The cross section of the plug rod 17 is L-shaped. The end of the plug rod 17 away from the connecting plate 12 is movably inserted into the adjacent insertion hole 18.

[0027] Working principle: The utility model is a factory voice broadcast device. During use, when installing the voice broadcast device body 7, first place the mounting plate 1 on the mounting surface, then move the cross plate 3, match the through hole 4 on the cross plate 3 with the mounting hole 2, and then fix it in the elevator with screws 5, then hold the cross bar 11 and the handle 10, the cross bar 11 moves toward the direction of the handle 10 under the action of the grip, the cross bar 11 drives the insertion rod 17 and the limit rod 16 to move through the connecting plate 12, the limit rod 16 drives the limit plate 15 to move, and when the connecting plate 12 moves Compress the spring 13, then move the voice announcer body 7, align the limit block 8 at the bottom of the voice announcer body 7 with the limit slot 7 at the top of the mounting plate 1, and limit the voice announcer body 7. At this time, the insertion rod 17 corresponds to the adjacent socket 18, and then release the grip on the crossbar 11 and the handle 10. The connecting plate 12 moves away from the fixing plate 14 under the action of the spring 13, and the connecting plate 12 drives the insertion rod 17 to be inserted into the inner cavity of the adjacent socket 18, thereby fixing the voice announcer body 7, thereby fixing the voice announcer body 7 to the mounting plate 1;

[0028] When the voice announcer body 7 needs to be disassembled for maintenance, the cross bar 11 and the handle 10 are then held. The cross bar 11 moves toward the handle 10 under the action of the gripping force. The cross bar 11 drives the insertion rod 17 and the limit rod 16 to move through the connecting plate 12. The limit rod 16 drives the limit plate 15 to move. When the connecting plate 12 moves, the spring 13 is compressed, and the insertion rod 17 moves away from the socket 18, thereby releasing the fixation of the voice announcer body 7. Then, the voice announcer body 7 is moved. At this time, the voice announcer body 7 can be removed, which is convenient for quick installation and removal of the voice announcer body 7 and subsequent maintenance.

[0029] That is, when the device is disassembling and maintaining the voice announcer body 7, by holding the cross bar 11 and the handle 10, the fixation of the voice announcer body 7 can be unlocked and the voice announcer body 7 can be moved at the same time, killing two birds with one stone, and the operation is convenient, which makes it easy to quickly install and disassemble the voice announcer body 7 and facilitate subsequent maintenance.
