Specific implementation process is as follows: the utility model need in use, first rotate forward starting motor B27, motor
The output shaft of B27 drives gear B 14 to rotate, and gear B 14 and 13 engagement rotation of gear A, gear B 13 drive screw rod A11 and screw rod
B25 rotation, screw rod A11 drive spiral shell block A12 level to move downward, and spiral shell block A12 drives the lower end of connecting rod A10 to move downward, connecting rod
A10 can be using the special shaft of connecting rod A and the junction spiral shell block A12 as center of circle clockwise oscillation, and the upper end of connecting rod A10 moves downward, even
Bar A10 drives rack 2 to move downward.While screw rod A11 drives spiral shell block A12 movement, screw rod B25 drives spiral shell block B26 horizontal
It moves right, spiral shell block B26 and spiral shell block A12 bit synchronization move, and spiral shell block B26 drives the upper end of connecting rod B24 to move right, connecting rod B24
Can be using the shaft of connecting rod B24 and the junction spiral shell block B26 as center of circle counter-clockwise swing, the upper end of connecting rod B24 moves downward, connecting rod
B24 and connecting rod A10 is to move synchronously, and connecting rod B24 drives rack 2 to move downward, and connecting rod B24 and connecting rod A10 is to move synchronously, and is led
Bar A9 play the guiding role to rack with guide rod B23.When connecting rod A12 and connecting rod B26 have vertical state to move to fully horizontal,
Rack 2 moves to bottom, and motor B27 stops operating.Start motor A22 at this time, the output shaft of motor A22 drives spiral shell
Bar C8 rotation, screw rod C8 drive connecting plate 21 to move downward, and connecting plate 21 drives push plate A3 and push plate B17 to move downward.When even
When fishplate bar 21 drives push plate A3 and push plate B17 to move to lower side, the guide groove A28 on push plate A3 stirs driving lever A4 and drives flywheel
A5 rotates 180 degree, and flywheel A5 drives shaft A6 to rotate 180 degree, and shaft A6 band engine-bed 16 rotates 180 degree.Meanwhile push plate B17
On guide groove B29 by driving lever B18 drive flywheel B19 rotate 180 degree, flywheel B drive shaft B20 rotate 180 degree, shaft B band
Engine-bed 16 overturns 180 degree, and shaft A6 and shaft B20 bit synchronization move.After base 16 overturns 180 degree, overturning starting is electronic
Base 16 in rack 2, is pushed back the opening of 1 upper end of body by machine B27, and loudspeaker 7 pronounces upwards.The effect of square 15 is
Loudspeaker 7 is protected, external force is avoided to make the impaired deformation of the paper disc of loudspeaker 7 and big clast is stopped to be attached on loudspeaker 7.
When not using speaker, the above process only need to be executed, loudspeaker 7 is overturn and is withdrawn in body 1.
The utility model is by the way that loudspeaker 7 to be fixed on base 16, and when needing using speaker, base 16 is overturn 180
Degree makes the external sounding upwards of loudspeaker 7, when not in use, base 16 is overturn 180 degree usually again, receive loudspeaker 7 downwards
It returns inside body 1.The probability that dust clast is attached on the paper disc of loudspeaker 7 can not only greatly be reduced in this way, and raised
Sound device 7 can also fall off dust clast after downwardly turning on paper disc, at the same overturn after loudspeaker 7 can also reduce liquid into
The probability for entering paper disc avoids paper disc by liquid corrosion, ensure that the voice quality of loudspeaker 7.
