The protective cover 2 is rotatably connected to the side of the battery slot 101, and the elastic locking piece 201 is movably connected in the fixing slot 102. The elastic locking piece 201 and the anti-detachment hook 202 are located on the same side of the protective cover 2, and the length and width of the protective cover 2 are equal to the length and width of the battery slot 101. The fixing slot 102 is opened in the battery slot 101, and the driving slot 104 is opened below the anti-detachment slot 103. One end of the spring 3 is fixedly connected to the top of the driving slot 104, and the other end of the spring 3 is fixedly connected to the limiting block 4. The stabilizing bar 401 is slidably connected in the driving slot 104. A gear-shaped groove is opened on the side of the limiting block 4. The shape of the driving wheel 5 is gear-shaped, and the driving wheel 5 is engaged in the gear groove on the side of the limiting block 4, and the driving wheel 5 is rotatably connected to the housing 1.

[0023] Specifically, an anti-skid groove 7 is provided on the side of the shell 1 to increase the friction when the user takes the shell 1 to prevent the shell 1 from falling. An anti-fall cover 6 is fixedly bonded to the bottom and corners of the shell 1 so that the anti-skid groove 7 can reduce the impact on the shell 1 when the shell 1 falls, thereby improving the shell 1's anti-fall ability and protecting the internal parts. A battery slot 101 is provided on the shell 1, and a fixing slot 102 is provided in the battery slot 101. A protective cover 2 is rotatably connected to the bottom of the battery slot 101 so that the protective cover 2 will not be separated from the battery slot 101 to prevent The protection cover 2 is lost and the protection of the battery is affected. An elastic locking piece 201 is fixedly connected to the protective cover 2. The elastic locking piece 201 is movably connected to the fixing groove 102, so that after the elastic locking piece 201 enters the fixing groove 102, it will open due to elasticity, thereby completing the initial fixation of the protective cover 2. An anti-detachment hook 202 is also fixedly connected to the protective cover 2. The anti-detachment hook 202 is movably connected to the anti-detachment groove 103 on the shell 1.

The limit block 4 is connected so that the limit block 4 can be affected by the elastic force of the spring 3, and the contact surfaces of the limit block 4 and the anti-drop hook 202 are both inclined surfaces, so that when the anti-drop hook 202 enters the anti-drop groove 103 and moves downward, the limit block 4 will be squeezed in the direction of the spring 3, so that it reaches the bottom of the limit block 4. When the anti-drop hook 202 reaches the bottom, the spring 3 will push the limit block 4 toward the anti-drop groove 103, so that the limit block 4 is located above the anti-drop hook 202, and then the anti-drop hook 202 is fixed in the driving groove 104, so that when the shell 1 falls and is impacted When the protective cover 2 is opened, the anti-detachment hook 202 will be blocked by the limit block 4, thereby preventing the protective cover 2 from opening, thereby preventing the battery from falling. A stabilizing rod 401 is fixedly connected to the limit block 4, and the stabilizing rod 401 is slidably connected in the driving groove 104, so that the limit block 4 is more stable when sliding in the driving groove 104. A driving wheel 5 is engaged with the limit block 4, and the driving wheel 5 is rotatably connected to the shell 1, so that when the user wants to open the protective cover 2, the limit block 4 can be moved toward the spring 3 by rotating the driving wheel 5, and then the anti-detachment hook 202 can be taken out from the anti-detachment groove 103.

[0024] The working principle and usage process of the utility model are as follows: first, install the battery into the battery slot 101, rotate the protective cover 2, so that the elastic locking piece 201 enters the fixing slot 102, and completes the preliminary fixation. At this time, the anti-detachment hook 202 will also enter the anti-detachment slot 103. As the anti-detachment hook 202 descends, the anti-detachment hook 202 will push the limit block 4 to move toward the spring 3, and then the anti-detachment hook 202 will reach the driving slot 104. At this time, the spring 3 will squeeze the limit block 4 toward the anti-detachment slot 103, so that the limit block 4 is located above the anti-detachment hook 202, completing the fixation of the anti-detachment hook 202, so that the protective cover 2 is completely fixed on the battery slot 101. When the shell 1 falls, the anti-fall sleeve 6 will reduce the impact force received by the shell 1 to protect the internal parts. The anti-detachment hook 202 will be blocked by the limit block 4 and will not leave the anti-detachment slot 103, thereby preventing the protective cover 2 from being dropped, thereby preventing the battery from falling and affecting the use of the hearing aid.
