Description

Orbital telescopic automatic board eraser

This creation is a type of orbital telescopic automatic eraser, especially an automatic eraser that can be moved on a track and wipes the blackboard in a telescopic manner.

According to the conventional electric brush eraser, such as the new patent of "Electric Eraser" in China's application No. 101220719, it is revealed that the main purpose is to mount the wheel on the four corners of the board so that it can roll on the blackboard and set the direction button on the surface of the board. It can be used to control the direction of the brush to roll, and the magnet, motor and battery are placed inside the eraser. The magnet can be used to adsorb on the blackboard and avoid falling off the board, so as to save the teacher's strength and time to wipe the blackboard.

However, the conventional electric board eraser can save the teacher's strength and time to wipe the blackboard, but it can not wipe all the corners of the entire blackboard, and no board eraser wipes the board with chalk ash, which is quite inconvenient and does not conform to The actual use of the demand.

It can be seen that there are still many shortcomings in the above-mentioned household items, which is not a good designer and needs to be improved.

In view of this, the creator of this case has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author of this case has finally achieved a practical and practical creation.

The main purpose of this creation is to provide an orbiting telescopic automatic eraser that can be moved on a track and wiped the blackboard in a telescopic manner.

According to the above purpose, the orbital running telescopic automatic eraser of the present invention mainly comprises: a track, a telescopic rod and at least one board cleaning machine; wherein the track is disposed at an upper end of a blackboard; the telescopic rod is disposed at the The rail is provided with a driving device. The end of the telescopic rod is provided with a squeegee, so that the telescopic rod can be moved to the left and right on the rail by the driving of the driving device, and can be extended upwards and downwards. Retracting, and rubbing the end of the board, on the surface of the blackboard, moving up, down, left, and right, and wiping all corners of the blackboard; the board is placed under the side of the blackboard Thereby, through the driving of the driving device, the board wipe can wipe all corners of the blackboard, and at the same time, the board rub can be displaced to the top of the board wiping machine, and the board wiping surface can be wiped to contact the board wiping machine, and the board wiping machine is used. Pressing the suction force, sucking off the chalk ash on the wiping surface of the board, achieving the purpose of easy to wipe the blackboard and clean the board.

Fig. 1 is a schematic view showing the appearance of a telescopic automatic board eraser for the creation of the orbit.

In order to make the examination committee members able to further understand and understand the purpose, shape, structure and function of the creation, the following examples are combined with the drawings, which are described in detail as follows: This creation is related to a kind of "orbital telescopic type". The automatic plate eraser, as shown in Fig. 1, is a track-running telescopic automatic eraser of the present invention, which mainly comprises: a track 11, a telescopic rod 12 and at least one plate washer 13.

The track 11 is disposed at an upper end of a blackboard 20.

The telescopic rod 12 is disposed on the rail 11 and is provided with a driving device (not shown). The end of the telescopic rod 12 is provided with a squeegee 14 for enabling the telescopic rod 12 to be driven by the driving device. The track 11 is moved to the left and to the right, and can be extended upward and downward, and retracted, and the end of the board 14 can be moved upward, downward, leftward, and rightward on the surface of the blackboard 20. Wipe all corners of the entire blackboard 20.

The eraser 13 is disposed below the two sides of the blackboard 20.

By the composition of the above components, when used, the driving of the driving device enables the eraser 14 to wipe all the corners of the blackboard 20, and at the same time, the eraser 14 can be displaced to the upper of the eraser 13, and the wiper 14 is lifted to make the eraser 14 The wiping surface contacts the board wiping machine 13, and uses the negative pressure suction force of the board wiping machine 13 to suck off the chalk ash on the wiping surface of the board wiping 14 to achieve the effect and purpose of easily erasing the blackboard and cleaning the board.

Referring to FIG. 1 , a board eraser 13 is respectively disposed under the two sides of the blackboard 20 .

The orbital telescopic automatic eraser provided by the present invention has the following advantages when compared with the conventional techniques described above:

1. The system can move on a track and wipe the entire blackboard in a telescopic manner, and after wiping, clean the chalk dust on the board.

In summary, the orbital telescopic automatic eraser of this creation does have an unprecedented innovative structure. It has not been found in any publications, and there is no similar product on the market. Therefore, its novelty should be no. doubt. In addition, the unique features and functions of this creation are far from comparable to the conventional ones, so it is indeed more progressive than the application, and it meets the requirements of the application requirements of the new patents in the Chinese Patent Law, and is legally filed.

The above description is only the best embodiment of the present invention, but the structural features of the present creation are not limited thereto, and any one who is familiar with the skill of the art can easily change or modify it in the field of creation.
