[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figure 1 , Figure 2 and Figure 4 As shown, the utility model provides a technical solution: a visualized hearing aid, including a display device 1, a data transmission line 2 is fixedly connected to the bottom of the display device 1, a recording device 3 is fixedly connected to the top of the data transmission line 2, a wearing buckle 4 is fixedly connected to the rear end of the recording device 3, a control button 5 is installed at the front end of the display device 1, and a protective cover 6 is slidably connected to the front end of the display device 1. The user hangs the recording device 3 on the clothes in front of the chest through the wearing buckle 4, records the sound through the recording device 3, and displays it in the form of text on the display device 1, and controls the device through the control button 5. When the device is not in use, the protective cover 6 is slid to cover the display device 1 to protect the display device 1 and prevent the display device 1 from being damaged by collision, while preventing the control button 5 from being accidentally touched.

[0025] Reference Figure 4 and Figure 6 As shown, in this embodiment: slide grooves 7 are provided on both sides of the display device 1, and sliders 8 are fixedly connected to both sides of the inner wall of the protective cover 6. When the user slides the protective cover 6, the sliders 8 on both sides of the protective cover 6 move inside the slide grooves 7 to assist the movement of the protective cover 6 and at the same time limit the movement range of the protective cover 6 to prevent the protective cover 6 from detaching from the surface of the display device 1.

[0026] Reference Figure 6 As shown, in this embodiment: a placement groove 9 is opened on the inner side of the slider 8, and a pulley 10 is installed inside the placement groove 9. When the user slides the protective cover 6, the pulley 10 on the inner side of the slider 8 rotates inside the placement groove 9, reducing the friction force when the protective cover 6 moves, making the movement of the protective cover 6 more labor-saving, and reducing the wear between the protective cover 6 and the display device 1.

[0027] Reference Figure 5As shown, in the present embodiment: a storage groove 11 is provided at the bottom of the protective cover 6, a connecting rod 12 is slidably connected inside the storage groove 11, a connecting plate 13 is fixedly connected to the bottom of the connecting rod 12, a limiting rod 14 is fixedly connected to the top of the connecting plate 13, a limiting groove 15 is provided at the bottom of the display device 1, when the user needs to use the display device 1, the connecting plate 13 is pulled to disengage the limiting rod 14 from the inside of the limiting groove 15, the angle of the connecting plate 13 is rotated 90 degrees, the protective cover 6 is moved upward, so that the screen of the display device 1 appears in the user's field of vision, the device is controlled by the control button 5 to convert the sound into text, and the protective cover 6 is moved downward after use to protect the display device 1, and the connecting plate 13 is rotated at the same time, the limiting rod 14 is aligned with the limiting groove 15 and inserted to fix the protective cover 6.

[0028] Reference Figure 5 As shown, in the present embodiment: a thrust spring 16 is fixedly connected to the bottom of the storage groove 11, and the top of the thrust spring 16 is fitted with the top of the connecting rod 12. By installing the thrust spring 16 inside the storage groove 11, the connecting rod 12 can be pushed upward to prevent the user from shaking while carrying the display device 1 so that the limit rod 14 is disengaged from the limit groove 15, thereby making the fixation of the limit rod 14 to the protective cover 6 more stable.

[0029] Reference Figure 2 As shown, in this embodiment: a curved plate 17 is installed at the rear end of the display device 1, and a Velcro 18 is installed inside the curved plate 17. The user tears off the Velcro 18, puts the wrist into the inner side of the curved plate 17, and fixes it with the Velcro 18, which is convenient for carrying the device with you. The display device 1 is fixed to the wrist, so that the user can check it at any time, and at the same time, both hands can be freed for easy access to items.

[0030] Reference Figure 3 As shown, in this embodiment: two fixing blocks 19 are fixedly connected to both sides of the rear end of the display device 1, and round rods 20 are fixedly connected to the opposite surfaces of the fixing blocks 19. The arc plate 17 is rotatably connected to the surface of the round rod 20. The user tears open the Velcro 18 and rotates the arc plate 17 to both sides to increase the space inside the arc plate 17. After putting the wrist into the interior of the arc plate 17, it is fixed by the Velcro 18, which makes it easy to fix the device to the wrist of users of different body shapes.

[0031] The practical working principle of the present invention is as follows: the user hangs the recording device 3 on the clothes in front of the chest by wearing the buckle 4, records the sound through the recording device 3, and displays it in the form of text on the display device 1, and controls the device through the control button 5. When the device is not in use, the sliding protective cover 6 covers the display device 1 to protect the display device 1 and prevent the display device 1 from being damaged by collision, and at the same time prevents the control button 5 from being accidentally touched. In the process of sliding the protective cover 6, the sliders 8 on both sides of the protective cover 6 move inside the slide groove 7 to assist the movement of the protective cover 6, and at the same time limit the movement range of the protective cover 6 to prevent the protective cover 6 from separating from the surface of the display device 1. In the process of sliding the protective cover 6, the pulley 10 on the inner side of the slider 8 rotates inside the placement groove 9 to reduce the friction force when the protective cover 6 moves, making the movement of the protective cover 6 more labor-saving, and at the same time reducing the wear between the protective cover 6 and the display device 1. When the display device 1 needs to be used, the connecting plate 13 is pulled to disengage the limiting rod 14 from the inside of the limiting groove 15, and the angle of the connecting plate 13 is rotated 90 degrees to move the protective cover 6 upward. , so that the screen of the display device 1 appears in the user's field of vision, and the device is controlled by the control button 5 to convert the sound into text. After use, the protective cover 6 is moved downward to protect the display device 1, and at the same time, the connecting plate 13 is rotated, and the limiting rod 14 is aligned with the limiting groove 15 and inserted to fix the protective cover 6. By installing a thrust spring 16 inside the storage groove 11, the connecting rod 12 can be pushed upward to prevent the shaking caused by the user carrying the display device 1 from causing the limiting rod 14 to be separated from the limiting groove 15, so that the limiting rod 14 is pressed against the protective cover 6 is fixed more stably. The user tears off the Velcro 18, puts the wrist into the inner side of the arc plate 17, and fixes it through the Velcro 18, which is convenient for carrying the device with you. The display device 1 is fixed to the wrist, so that the user can check it at any time, and at the same time, the hands can be freed for easy access to items. By tearing off the Velcro 18, the arc plate 17 is rotated to both sides to increase the space inside the arc plate 17. After putting the wrist into the interior of the arc plate 17, it is fixed by the Velcro 18, which is convenient for fixing the device to the wrists of users of different body shapes.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
