In the figure: 1. an electric piano body; 2. a keyboard cover; 3. a sliding shaft; 4. a gear; 5. a guide rail; 6. a tooth row; 7. a microswitch member; 8. a vibration damping pad; 9. and (6) pressing a key.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, the present invention provides a technical solution: the utility model provides a push-and-pull switch formula piano, including fender body 1, keyboard cover 2, sliding shaft 3, gear 4, guide rail 5, the tooth row 6, micro-gap switch spare 7, damping pad 8 and button 9, the upside surface mounting of fender body 1 has keyboard cover 2, and the both sides of keyboard cover 2 all are connected with sliding shaft 3, sliding shaft 3's the outside is provided with gear 4, and sliding shaft is located guide rail 5's inside, and gear 4's the outside and tooth row 6 interconnect, the inner wall of fender body 1 and micro-gap switch spare 7's bottom interconnect, the place ahead surface of fender body 1 is provided with damping pad 8, and the last surface mounting of fender body 1 has button 9.

The keyboard cover 2 forms a sliding structure with the guide rail 5 through the sliding shaft 3 and the gear 4, and the gear 4 is connected with the gear row 6 in a meshing manner, so that the device can fix the keyboard cover 2, and the situation that the keyboard cover 2 shakes is avoided.

The surface of micro-gap switch spare 7 is insulating fire-retardant plastic material, makes the device pass through the slip of keyboard lid 2, can use the extrusion force to micro-gap switch spare 7, later alright open the power of fender body 1.

The lower surface of the vibration damping pad 8 is sticky, and the upper surface of the vibration damping pad 8 is matched and connected with the lower surface of the keyboard cover 2, so that the device can complete the protection effect on the keyboard cover 2 through the vibration damping pad 8, and the keyboard cover 2 is prevented from being damaged.

When the piano keyboard is used, firstly, a user pushes the keyboard cover 2 from outside to inside, the sliding shaft 3 installed on the keyboard cover 2 rotates towards the inside through the guide rail 5 and the gear 4, when the keyboard cover 2 is completely opened, the bottom of the keyboard cover 2 can trigger the micro switch piece 7 installed behind the electric piano body 1, so that a power switch of the electric piano body 1 is opened, a power adapter outside the electric piano body 1 supplies power to the power amplifier of the electric piano body 1 through the travel switch, a voltage reduction circuit on the power amplifier reduces the voltage and then sends the voltage to the mainboard, the electric piano body 1 starts to work, and meanwhile, the content which is not described in detail in the specification belongs to the prior art known by professionals in the field.
