Description

Turnover blackboard

Technical Field

The utility model relates to a turnover erasing blackboard.

Background

The blackboard in the prior art basically adopts an integral whole writing board body, and can only be erased by using the blackboard eraser manually during erasing, thereby being time-consuming and labor-consuming, and chalk dust flies around to affect the health. In some improvement measures, an electric blackboard eraser (for example, patent CN106515282A, CN203063400U and the like) is adopted, but in the existing improvement measures, the erasing surface of the writing board body is always exposed, so that chalk dust is difficult to stop flying, and the defect of high dust collection noise is probably caused by adding a dust collection function.

Disclosure of Invention

In view of the defects in the prior art, the technical problem to be solved by the utility model is to provide a turnover wiping blackboard.

In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a blackboard is cleaned in upset, includes the frame, vertical equipartition has a plurality of transversely extending's clipboard body on the preceding rectangle inside casing of frame, the vertical cross-section shape of clipboard body is equilateral triangle, the tip center of clipboard body is all installed on the frame through the rotatory pivot of motor drive, have the interval between the tip of clipboard body and the tip of frame, all be equipped with the blackboard eraser on this interval, the blackboard eraser all carries out the transversely reciprocal translation through electric mechanism drive for the translation contacts the upper portion inclined plane of clipboard body and cleans, the bottom of frame is equipped with the drawer that is used for collecting powder.

Preferably, the number of the blackboard erasers is the same as that of the writing board bodies and corresponds to the number of the writing board bodies one by one, and the wiping surfaces of the blackboard erasers are parallel to the upper inclined surfaces of the writing board bodies.

Preferably, the electric mechanism comprises a ball screw transversely arranged in the frame, the ball screw is driven to rotate by a motor, a movable seat body is screwed on the ball screw, and the upper end and the lower end of the movable seat body pass through guide rods transversely extending in the frame.

Preferably, the rear of the frame body of the blackboard eraser is connected with the movable seat body through the adapter, and the adapter is fastened with the frame body of the blackboard eraser and the adapter is fastened with the movable seat body through screw threads.

Preferably, the drawer at the bottom of the frame is pulled forward and backward, pulled forward and pushed backward, and a handle is arranged in front of the drawer.

Preferably, the space is also respectively provided with a scraping plate, and the upper edges of the scraping plates are higher than the wiping surface of the blackboard eraser body.

Preferably, the distance width is larger than the width of the blackboard eraser.

Preferably, the end cover at the end part of the frame is connected to the frame through screws in a screwed mode, and the disassembly and assembly are convenient.

Compared with the prior art, the utility model has the following beneficial effects:

when the turnover erasing blackboard is used, the plurality of transversely extending writing board bodies are equilateral triangles, and the plurality of writing board bodies rotate in sequence to make the front exposed board surfaces spliced into vertical writing surfaces for writing on boards. When all erasing is needed, the plurality of writing board bodies rotate one by one in sequence to enable the writing surface to rotate into the frame to become an upper inclined plane of the writing board body, then the electric mechanism drives the blackboard eraser positioned in the interval area to translate, the blackboard eraser starts to contact with the upper inclined plane of the writing board body and wipe in an interference manner, the blackboard eraser resets to the interval area after wiping is finished, the wiping process is carried out in the frame, chalk dust is not easy to be exposed and fly upwards, dust can finally fall into the drawer to be concentrated, and large noise of dust collection is avoided. In the wiping process, the new writing surface is spliced into a vertical new writing surface after the new writing surface exposed from the front surface is turned, and the new writing can be started without waiting for the old writing surface (the upper inclined surface) to be completely erased. When the part of the writing board needs to be erased, the board which does not need to be erased temporarily can be selectively written on part of the writing board body, and only other writing board bodies rotate when the part of the writing board body needs to be erased, and the writing board body which does not need to be erased does not rotate.

The utility model will be described in further detail with reference to the drawings and the detailed description.
