[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] A mobile screen clearing electronic label, comprising a privacy switch buckle plate and a display screen, a connecting column is fixed in the middle of the inner side of the back plate of the buckle plate, and the display screen is provided with a hole in the middle of the rear shell, so that the connecting column of the buckle plate can press the privacy switch, the privacy switch is located on the main board in the display screen and is a non-self-locking press switch, the buckle plate and the display screen are assembled together through clamping, the connecting column presses the button of the privacy switch, the button drives the pin at the bottom to be connected with the GPIO interface of the control main board in the display screen, and the display screen normally displays a picture, when the display screen is separated from the buckle plate, the button and the pin of the privacy switch are reset under the action of the compression spring, the pin is disconnected with the GPIO interface of the control main board in the display screen, the display screen clears the original picture and switches to a pure white picture.

[0006] Further, the display screen is an ink screen.

[0007] Further, the lower end of the buckle plate is provided with a clamping groove, the upper end of the buckle plate is provided with a clamping point, the lower end of the display screen is clamped in the clamping groove, and the positioning groove at the upper end of the display screen is connected with the clamping point through clamping buckle.

[0008] The utility model adopts the above technical scheme, can realize screen clearing after the display screen is separated from the buckle plate, and avoids displaying wrong information. The utility model has simple structure and is easy to realize. BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model will be further explained in detail in connection with the drawings and specific embodiments:

[0010] Figure 1 It is the structural schematic diagram of the utility model;

[0011] Figure 2 For Figure 1 Enlarged view of privacy switch and connecting post;

[0012] Figure 3 For controlling the circuit diagram of the main board on the display screen display picture. DETAILED DESCRIPTION

[0013] As Figures 1-3 shown, the utility model discloses a mobile screen cleaning electronic label, including the buckle plate 1 and display screen 2, the buckle plate 1 is positioned when the installation of display screen 2, and display screen 2 is ink screen. The lower end of buckle plate 1 is equipped with the clamping groove 11, and the upper end of buckle plate 1 is equipped with the clamping point 12, when display screen 2 buckling connection is in buckle plate 1, the lower end of display screen 2 is connected in the clamping groove 11, and the positioning groove of display screen 2 upper end and clamping point 12 buckling connection.

[0014] The middle part of the backboard inside of buckle plate 1 is fixed with connecting post 3, and the rear shell of display screen 2 is centrally perforated, so that buckle plate 1 connecting post 3 can press to privacy switch 4;Privacy switch 4 is located on the inside main board of display screen 2, and is a non-self-locking press switch;

[0015] When buckle plate 1 and display screen 2 are assembled together by clamping, connecting post 3 presses the button of privacy switch 4, the button drives the pin at the bottom to be connected with the GPIO interface of the inside control main board of display screen 2, and display screen 2 normally displays picture. When display screen 2 and buckle plate 1 are separated, the button 41 and pin 42 of privacy switch 4 are reset under the action of compression spring 43, and pin 42 is disconnected with the GPIO interface of the inside control main board of display screen 2, and display screen 2 clears the original picture, and switches to pure white picture, to avoid displaying wrong information.

[0016] The above describes the specific embodiment of the utility model, but those skilled in the art should understand that this is only illustrative, and those skilled in the art can make various changes or modifications to this embodiment without departing from the principles and essence of the utility model, and these changes and modifications all fall within the protection scope of the utility model.
