Examples

As shown in fig. 1 to 3, an accounting teaching aid comprises a base 1, wherein a support leg with a telescopic function is fixed on the ground of the base 1, a support 8 and a vertical frame 20 are fixed on the base 1, a writing board 5 is fixed on the support 8, a wiping device for cleaning the writing board 5 is arranged on the base 1, a rotating wheel 12 is rotatably connected on the vertical frame 20 in a fixed-shaft mode, and a driving part for driving the rotating wheel 12 is arranged on the base 1.

In this embodiment, the writing board 5 is discoid, and the center of writing board 5 has seted up the show window 6, and the cross section of runner 12 is regular hexagon structure, and each side of runner 12 all can correspond with show window 6, and each side of runner 12 all is fixed with slot 15, and the central axis department of runner 12 is fixed with pivot 16 to through 16 dead axles of pivot rotation connection on grudging post 20, pivot 16 only can do the rotary motion around its self central axis on grudging post 20.

In this embodiment, wiping arrangement includes that the dead axle rotates swivel 4 of connection in 5 outside limits departments of clipboard and fixes motor 2 on base 1, swivel 4 only can be around the rotary motion of its self central axis on clipboard 5, be fixed with brush strip 7 on swivel 4, the directional centre of a circle of swivel 4 of brush strip 7, the output shaft end of motor 2 is fixed with friction pulley 3, and

friction pulley

3 and 4 rolling contact of swivel, certain frictional force has between friction pulley 3 and the swivel 4, this frictional force can drive swivel 4 and rotate on clipboard 5.

In this embodiment, the driving portion includes a sliding frame 19 fixed on the base 1, a rack 11 is slidably connected to the sliding frame 19, a protruding rod 13 is fixed to the upper end of the rack 11, the protruding rod 13 is connected to the upper end of the sliding frame 19 through a spring 14, a contact 9 is fixed to the lower end of the rack 11, a first touch switch 17 is fixed to the stand 20, a second touch switch 18 is fixed to the sliding frame 19, the first touch switch 17 is located above the second touch switch 18, the contact 9 is located between the first touch switch 17 and the second touch switch 18, and the first touch switch 17 and the second touch switch 18 are electrically connected to the motor 2 respectively.

In this embodiment, the driving portion further includes a ratchet 10, an inner ring of the ratchet 10 is fixed at an end of the rotating shaft 16, and an outer ring of the ratchet 10 is engaged with the rack 11.

The utility model discloses a principle and advantage: this kind of accounting teaching aid operates as follows when using:

the accounting documents to be explained and taught are correspondingly inserted into the slots 15 on each side surface of the rotating wheel 12 in advance, then the motor 2 is inserted with a power supply, one side surface of the rotating wheel 12 is opposite to the display window 6, so that the accounting documents on the slots 15 on the side surfaces can be displayed from the display window 6 to be watched by students, and then the accounting documents displayed on the display window 6 can be marked, annotated and explained on the writing board 5;

when the next accounting document needs to be explained, the convex rod 13 is pressed downwards to enable the convex rod 13 to receive a downward force and to synchronously move the rack 11 and the contact 9 downwards along the sliding frame 19, the downward movement of the convex rod 13 applies a downward force to the spring 14 to enable the spring to be compressed and shortened and obtain a restoring force, the downward movement of the rack 11 drives the outer ring of the ratchet 10 to rotate, the outer ring can drive the inner ring to synchronously rotate through the pawl, the rotation of the inner ring synchronously drives the rotating shaft 16 to rotate, so that the rotating wheel 12 is driven to rotate, when the contact 9 moves downwards and contacts the second touch switch 18, the rack 11 stops moving downwards, the rack 11 drives the rotating wheel 12 to rotate through the ratchet 10 by an angle which just enables the rotating wheel 12 to replace one side surface to correspond to the display window 6, when the contact 9 contacts the second touch switch 18, the motor 2 is electrified to work, and the motor 2 drives, the friction wheel 3 drives the rotating ring 4 to rotate through friction force, the rotating ring 4 drives the brush strip 7 to synchronously rotate, and the writing board 5 is wiped when the brush strip 7 rotates, so that the writing board 5 is wiped while accounting documents are replaced, the operation is simple and convenient, and time and labor are saved;

when the contact 9 contacts the second proximity switch 18, the convex rod 13 is released, the convex rod 13 is not restrained downwards, and under the action of the restoring force of the spring 14, the rack 11 and the contact 9 are driven to synchronously move upwards along the sliding frame 19, the rack 11 moves upwards to drive the outer ring of the ratchet wheel 10 to rotate, at the moment, the outer ring can not drive the inner ring to rotate, the rotating wheel 12 keeps still, when the contact 9 moves upwards along with the rack 11 and approaches the first touch switch 17, when the contact 9 contacts the first touch switch 17, the motor 2 is powered off, the friction wheel 3 stops driving the rotating ring 4 to rotate, in the process of moving the rack 11 upwards, the motor 2 drives the rotating ring 4 to rotate for at least one circle through the friction wheel 3, so that the complete wiping of the writing board 5 can be ensured, but also can realize the self return of rack 11 so that change accounting document next time, whole operation process saves time to reduce the labour, improve teaching efficiency.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
