Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
The following specific examples of the utility model is only the explanation to the utility model, is not new to this practicality
The limitation of type, those skilled in the art can as needed make without creativeness the present embodiment after reading this specification
The modification of contribution, but as long as all being protected by Patent Law in the right of the utility model.
A kind of electronic blackboard, as shown in Figure 1, including the blackboard framework 1 being fixedly connected on wall, being fixedly connected on blackboard
Electronic display 2 in frame 1 is slided with the writing blackboard 3 in 2 both sides of electronic display, two pieces of writing blackboards 3 level is arranged
It is dynamic to be connected on blackboard framework 1, and writing blackboard 3 is located at the front of electronic display 2.
As shown in Fig. 2, the back side of two pieces of writing blackboards 3 has been fixedly connected with swipe 5, and if being fixedly connected in swipe 5
Dry bristle 7, bristle 7 are abutted with electronic display 2.
The electronic display 2 when not in use, pushes two pieces of writing blackboards 3 that its level on blackboard framework 1 is made to slide and hide
Electronic display 2 is kept off, dust-proof effect is played；And after curricula, push writing blackboard 3 that it is made to block electronical display
During screen 2, swipe 5 moves horizontally therewith, and bristle 7 swipes the dust adhered in electronic display 2；When curricula is complete
Bi Hou, without additionally clearing up electronic display 2 again, the bristle 7 while pushing writing blackboard 3 that it is made to block electronic display 2
Electronic display 2 is cleared up, it is easy to operate, quick.
As shown in Figures 2 and 3, horizontal be slidably connected two is located at the dust-collecting box of 2 lower section of electronic display on blackboard framework 1
4, the top of dust-collecting box 4 is provided with opening, and the glide direction of two dust-collecting boxes 4 is consistent with the glide direction of writing blackboard 3.When
When writing blackboard 3 is located at 2 both sides of electronic display and does not block electronic display 2, dust-collecting box 4 can be accommodated in respectively and it
Between adjacent writing blackboard 3 and blackboard framework 1, space is saved.Between writing blackboard 3 and dust-collecting box 4 adjacent thereto
It is provided with linkage mechanism 6, the linkage mechanism 6 linkage dust-collecting box 4 in the sliding horizontal close to electronic display 2 of writing blackboard 3 leans on
The 2 horizontal sliding of nearly electronic display.
The linkage mechanism 6 includes the first rack 61 being fixedly connected on writing blackboard 3, is fixedly connected on dust-collecting box 4
The second rack 62 and be rotationally connected with the first gear 63 on blackboard framework 1 and being meshed and second gear 64, the first tooth
Item 61 is parallel to the second rack 62, and the first rack 61 is meshed with first gear 63,64 phase of the second rack 62 and second gear
Engagement.The diameter of first gear 63 is less than the diameter of second gear 64.And two dust-collecting boxes 4, when being in contact, the first rack 61 is
It is disengaged with corresponding first gear 63.
When pushing writing blackboard 3 that it is made to be slided close to electronic display 2, pass through the first rack 61, first gear 63, second
The gearing of gear 64 and the second rack 62 link the second rack 62 and dust-collecting box 4 always some stretch out writing blackboard 3
Outside, it ensure that bristle 7 swipes the dust in electronic display 2 and can fall in dust-collecting box 4 always.Therefore, two dust-collecting boxes 4
When being in contact, writing blackboard 3 does not shelter from electronic display 2 completely, and the first rack 61 is disengaged with first gear 63 at this time,
It may continue to push two pieces of writing blackboards 3, and bristle 7 made to continue to clear up the dust of 2 screen of electronic display, while making should
Class dust is fallen in dust-collecting box 4.
Specific work process：After curricula, writing blackboard 3 is pushed to make it on blackboard framework 1 close to electronic display
The horizontal sliding of display screen 2, swipe 5 move horizontally therewith, and bristle 7 swipes the dust adhered on the screen of electronic display 2.
