This clipboard with dustproof function is through locating the board body 1 with the blackboard eraser subassembly slip on to through the power device drive, and then can avoid the trouble that the manual work was erased, reduced teachers and students' working strength.

In the structure, the blackboard body 1 is a blackboard in the existing structure, the whole body is cuboid, the inner side face and the outer side face are respectively arranged on two opposite sides of the blackboard body 1, and the power device in the embodiment comprises a rotating motor 2 fixedly connected to the top of a sliding block described below, a rack 3 arranged along the length direction of the upper edge of the blackboard body 1, and a gear 4 fixedly connected to a power output shaft of the rotating motor 2 and in meshed transmission with the rack 3. When the blackboard eraser is used, a button can be arranged on the wall body at the position of the board body 1 to control the rotating motor 2 to start and rotate forward and backward, so that the rotating motor 2 drives the blackboard eraser assembly to move transversely (namely to move back and forth along the length direction of the board body 1), and the chalk fonts can be erased.

In order to facilitate the sliding arrangement of the board eraser assembly, as shown in fig. 1 to 3 in combination with fig. 4 to 6, in this embodiment, guide rails 5 are respectively fixedly connected to the upper edge and the lower edge of the board body 1 along the length direction thereof via bolt pairs, and sliding blocks 6 are slidably disposed on the guide rails 5, and the board eraser assembly is disposed between the two sliding blocks 6. In a specific structure, the guide rail 5 in this embodiment is a rectangular bar structure, the two opposite sides of the guide rail are respectively formed with an arc-shaped or V-shaped guide groove 501, the slider 6 is integrally U-shaped, the two opposite inner walls of the U-shaped groove are respectively formed with a guide protrusion 601 matched with the guide groove 501, and a sliding structure with the guide protrusion 601 and the guide groove 501 is adopted, so that the sliding stability of the slider 6 can be ensured, and the slider 6 can be prevented from falling off from the side of the guide rail 5. In addition, in order to prevent the slider from sliding off the end of the guide rail, the stopper 7 is provided at the end of the guide rail in this embodiment.

The board assembly of wiping in this embodiment includes that top and bottom link firmly respectively in the connecting plate 8 on two 6 lateral parts of slider to and locate the board 10 on the 8 medial surfaces of connecting plate, and link firmly the bounding wall 9 of arranging the branch in the board both sides on connecting plate 8. In this embodiment, the eraser 10 is a blackboard eraser in the prior art, and is adhered to or fixed to the inner side surface (the inner side surface is the side surface opposite to the board body 1) of the connecting plate 8 by bolts, and the coaming 9 and the outer side surface of the board body 1 have a small gap, so that dust erased by the eraser 10 can be blocked, and the dust cannot fly out of the coaming. Meanwhile, a flow channel is formed inside the connecting plate 8 in the embodiment, a plurality of dust suction ports 11 communicated with the flow channel are formed on the inner side surface of the connecting plate 8, and a negative pressure system communicated with the flow channel is fixedly connected to the inner side surface of the plate body 1. In order to facilitate the processing of the flow channel, as shown in fig. 7, in this embodiment, the connecting plate may be formed by splicing two connecting sub-plates 801, and a flow channel main groove 12 and a flow channel sub-groove 13 communicating with the flow channel main groove 12 are respectively formed on the two connecting sub-plates 801, the dust suction port 11 is provided on one of the connecting sub-plates 801 and communicates with the flow channel sub-groove 13, after the two connecting sub-plates 801 are attached, the flow channel sub-groove 13 and the flow channel main groove 12 enclose the flow channel, and during the assembly, the connecting plate may be directly fixed to the slider 6 through a connecting hole at the end of the connecting sub-plate 801 by a bolt, and the connecting pipe 14 communicating with the flow channel may be inserted into the end of the connecting plate. Thereby can adsorb enclosing the dust that keeps off in the bounding wall through setting up the dust suction inlet to form the negative pressure in the clearance department that bounding wall and plate body formed, thereby further reduced the showy volume of dust.

The negative pressure system in this embodiment includes the dust collection box 15 and the vacuum pump 16 that link firmly on the plate body 1 medial surface, and this dust collection box 15 passes through the pipeline and communicates with vacuum pump 16, and this vacuum pump can adopt the miniature vacuum pump among the prior art to and the connector 20 of intercommunication on this dust collection box 15 communicates with foretell connecting pipe 14 through the flexible tube that does not show in the figure, in order to form the intercommunication with the runner. In addition, in the present embodiment, a discharge opening is formed at the bottom of the dust collection box 15 to be opened and closed, so that the collected dust can be taken out periodically. In this embodiment, by providing the dust collection box 15, the pressure is reduced after the dust enters the dust collection box through the duct, and the dust falls down by the gravity of the dust collection box. Of course, in this embodiment, a filter screen may be provided at the inlet of the vacuum pump 16 to prevent the dust collecting box 15 from being sucked into the vacuum pump after being filled.

In order to prevent the damage caused by the direct contact between the dust collection box 15 and the vacuum pump 16 and the wall body, a plurality of positioning columns 17 are fixedly connected to the inner side surface of the plate body 1 in the embodiment, and the length of each positioning column 17 is greater than the thickness of the dust collection box and the vacuum pump. Meanwhile, in order to avoid a small amount of dust falling into the guide groove of the rail, in this embodiment, a material collecting groove 18 is formed along the length direction of the lower edge of the plate body 1 to collect a small amount of falling dust, and one of the rails 5 is fixed on the outer side surface of the collecting groove 18, meanwhile, in order to ensure that the eraser 10 is parallel to the plate body 1, a strip-shaped plate 19 is formed along the length direction of the upper edge of the plate body 1 in this embodiment, the strip-shaped plate 19 and the material collecting groove 18 are equal in thickness, and the other rail 5 is fixed on the strip-shaped plate 19.

This clipboard with dustproof function can avoid the trouble that the manual work was erased through setting up power device, and sets up dust suction inlet 11 and inhales the dust, can avoid the dust to fly out in the air and influence teachers and students' health.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
