Abstract

The invention discloses an erasing device for an electronic whiteboard, belonging to the field of erasing devices for an electronic whiteboard. An erasing device for an electronic whiteboard, comprising an electronic whiteboard and a slider. The two ends of the electronic whiteboard are provided with inner chutes, and the two ends of the slider are provided with card angles. The card angles are in close contact with the upper and lower ends of the left and right ends of the electronic whiteboard. The slider The inner side is connected with one end of the sliding rod, the sliding rod is connected with the inner chute, the upper end of the slider is connected with the bottom surface of the connecting block, the control box is fixedly installed between the connecting blocks, the middle part of the upper surface of the control box is connected with the sleeve column, and the upper end of the sleeve column is connected with the pressing block Connection, the left side of the lower surface of the control box is connected with the first connecting column, the right side of the lower surface of the control box is connected with the second connecting column, and the lower ends of the first connecting column and the second connecting column are connected with the upper surface of the eraser device. The present invention realizes the effective erasing effect on the electronic whiteboard by being provided with a control box, an erasing device, combined with the lever device and the sliding action of the slider, and achieves the purpose of effectively avoiding accidental touches during the erasing process and preventing the erasing device from being easily damaged.

Description

technical field [0001] The invention relates to the field of erasing devices for electronic whiteboards, in particular to an erasing device for electronic whiteboards. Background technique [0002] At present, there are three types of erasing methods on the electronic whiteboard: the first type is hardware support, through certain technical processing on the screen, the palm can be recognized, gestures can be used for multi-point erasing, but because the material of the screen is generally LCD screen , to erase on it by hand, there is a certain amount of friction, and it feels bad; the second type is software support, using tools to develop a virtual eraser component, call the eraser, push and touch to erase, but the user You need to click to switch between the eraser and brush with your hands. There is a switching interaction, the operation is relatively complicated, and it is inconvenient to use. After using the eraser, you need to click the brush to return to the brush st...
