Abstract

The utility model relates to a self-cleaning writing board which can make the aim of automatically cleaning the board realized by the rotation of a writing rotary board (1) and a brush (10), belonging to the technical field of stationery. The utility model comprises the writing rotary board (1), a writing shim plate (2) arranged on the inner side of the writing rotary board (1) and fixed on a wall surface, a cleaner arranged on one side of the writing rotary board (1) and a driven rotary rod (4) arranged on the other inner side of the writing rotary board (1). The writing board is cleaned by self by the rotation of the writing rotary board (1) and the brush (10) in the cleaner (3), the outer surface of which is sealed. The utility model has the advantages of time and labour saving, convenient collection of chalk dust, simple structure and low cost, and is suitable for various schools, and the chalk dust can not fly away and drops to the lower part along the inner wall of the cleaner (3).

Description

The self-cleaning clipboard

The utility model is a kind of by writing the self-cleaning clipboard that the rotation of flap and hairbrush reaches automatic brush board purpose, belongs to the school supply and stationery technical field.

Artificial brush board is usually used in the present widely used blackboard back of writing, and chalk dust flies upward everywhere behind time-consuming, effort and the brush board, influences the healthy of student and teacher; Though 992310067 patents can reach the purpose of automatic erasing blackboard, because its complex structure is implemented difficulty.

The purpose of this utility model provides a kind of self-cleaning clipboard by the cleaner automatic erasing blackboard.

The purpose of this utility model is achieved in that this clipboard comprises and writes flap, is installed in that to write flap inboard and be fixed on writing backing plate on the metope, is contained in the cleaner of writing flap one side, is contained in the driven dwang of writing another inboard of flap.

It is box-like that cleaner is, box wall opening place with write flap width coupling, the box internal upper part is equipped with motor, motor links to each other with two belt pulleys by axle, belt pulley links to each other with the hairbrush belt pulley that the hairbrush dwang is housed by belt, hairbrush is contained on hairbrush dwang and the follower lever, and another belt pulley links to each other with the big belt pulley that driven dwang is housed by belt, and driven dwang is contained in and writes the flap inboard; Writing flap is that plastics are done circlewise.

Before hairbrush placed and writes the flap working face, bristle was uniform along lateral surface;

Writing backing plate is rectangular-shaped, a side trough of belt, well width with write flap width coupling, its length with write flap working face size coupling.

The utility model compared with prior art has following advantage:

1, the utility model adopts the cleaner of outer surface sealing to rotate from wiping clipboard by flap, and is time saving and energy saving, and chalk dust can not fly around, and is convenient to collect but fall the bottom along the cleaner inwall.

2, this clipboard is simple in structure, and cost is low, is suitable for all kinds of schools and uses.

The utility model drawing is described as follows:

Fig. 1 is the main TV structure schematic diagram of the utility model self-cleaning clipboard.

Fig. 2 is the plan structure schematic diagram of the utility model self-cleaning clipboard.

Fig. 3 is the left TV structure schematic diagram of the cleaner of the utility model self-cleaning clipboard.

Fig. 4 is the structural representation of the cleaner driving section of the utility model self-cleaning clipboard.

Below in conjunction with accompanying drawing the utility model embodiment is described further: (seeing accompanying drawing 1,2,3,4) self-cleaning clipboard comprises that plastics make the annular flap (1) of writing, be installed in that to write flap (1) inboard and be fixed on writing backing plate (2) on the metope, writing backing plate (2) is rectangular-shaped, one side trough of belt, well width with write flap (1) width coupling, its length with write flap (1) working face size coupling; Cleaner (3) is contained in writes flap (1) one side, cleaner (3) is box-like, box wall opening place with write flap (1) width coupling, the box internal upper part is equipped with motor (5), motor (5) links to each other with belt pulley (6,7) by axle, belt pulley (7) links to each other with the hairbrush belt pulley (9) that hairbrush dwang (8) is housed by belt, hairbrush (10) is contained on hairbrush dwang (8) and the follower lever (11), belt pulley (6) links to each other with the big belt pulley that driven dwang (4) are housed (12) by belt, and driven dwang (4) is contained in another inboard of writing flap (1); Before hairbrush (10) placed and writes flap (1) working face, bristle was uniform along lateral surface.

The utility model operation principle: drive belt pulley (6 by motor (5), 7), belt pulley (7) drives the hairbrush belt pulley (9) that hairbrush dwang (8) is housed by belt and rotates, and the hairbrush (10) that drive is contained on hairbrush dwang (8) and the follower lever (11) rotates, simultaneously, belt pulley (6) drives the big belt pulley (12) that driven dwang (4) are housed by belt and rotates, and driven dwang (4) is contained in writes flap (1) inboard, because bristle is close to and is write flap (1), rotate the purpose that can reach the outwash clipboard when writing flap (1) and hairbrush (10).
