[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] In order to achieve the above purpose, the utility model provides the following specific implementation methods:

[0036] Example 1: Figure 1-4 As shown, a writing device with an erasable writing board comprises two panels 1, the two panels 1 are integrally arranged and made of the same PP plastic or paper-plastic composite material or wood-plastic composite material or metal-plastic composite material;

[0037] The panels 1 are folded relative to each other through the folding ridge 3, and the thickness of the folding ridge 3 is less than the thickness of the panel 1, so that the inner side or outer side or both sides of the folding section of the folding ridge formed between the panels 1 are inverted trapezoidal grooves, U-shaped grooves or V-shaped grooves, which are convenient for folding; Figure 3 In this embodiment, the folded outer side section of the folded ridge formed between the two panels 1 is a V-shaped groove. Other various forms can be selected arbitrarily and are no longer drawn in sequence.

[0038] The thickness of the panel 1 is 0.5 mm to 5 mm, and the thickness of the folding ridge line 31 is 0.05 mm to 2 mm.

[0039] At least one erasable surface 11 for writing is provided on the panel 1. In this embodiment, the erasable surface 11 is arranged on the folding surface of the two panels 1. At the same time, a right-angle mark 5 is provided to facilitate automatic focusing and image adjustment when taking photos with digital devices.

[0040] At least one pair of magnetic magnets 4 or snaps or hooks or protrusions are provided on the relatively folded inner side surfaces of the two panels 1, so that there is a gap of 1 to 4 mm between the folded inner side surfaces of the two panels 1 in the folded state to prevent writing marks from being rubbed against each other;

[0041] The panel 1 has arc-shaped edges and corners to prevent collision.

[0042] When in use, the writing device with an erasable board is opened to lay the two panels 1 flat. Since the folded surfaces of the two panels 1 are flat, the erasable surfaces 11 thereon can be written with a whiteboard pen, which is convenient for erasing and fully utilizing the board surface. The right-angle marks 5 on the board surface are also convenient for taking photos and archiving with digital devices. When the device is closed, the thickness of the magnetic sticker 4 can leave a gap between the panel 1 and the bottom plate 2 to prevent the writing marks from being rubbed against each other.

[0043] Example 2: Figure 5-8 As shown, it is the same as Example 1, except that: there are two panels 1, and a panel connecting device is provided on the end panel surface where the two panels 1 are separated, so as to facilitate the support and display of the erasable plane 11 on the two panels 1 and the folding and storage of the two panels 1.

[0044] The panel connecting device includes: a long adhesive strip 41 is provided on the separated end surface of at least one panel 1, a Velcro 42 corresponding to the adhesive strip 41 is provided on the other panel 1, and a slot 43 is provided on the panel 1 for embedding or inserting the adhesive strip 41, so that when the erasable plane 3 is supported for display, the separated end of the panel 1 can be placed stably, and the long Velcro 41 can be a leather strip or silicone strip or cloth strip or elastic band connected with Velcro.

[0045] In the folded state of the present embodiment, the hook and loop fasteners 42 at the separated ends of the panels 1 act as the magnetic magnet 4, so that there is a gap of 1 to 4 mm between the folded inner surfaces of the two panels 1 in the folded state, thereby preventing writing marks from being rubbed against each other.

[0046] When the embodiment is in the open state, the two panels 1 cooperate with the adhesive strip 41 to form a display board with triangular sides, which facilitates the support and display of the erasable surface 11 provided on the panel 1, and is combined into a triangular note board or desk sign.

[0047] Example 3: Figure 9-11 As shown, it is the same as the embodiment 1, except that: a spine connecting device 2 is provided between the two panels 1, and the spine connecting device 2 is used to connect the two panels 1, and at the same time, the two panels 1 can be folded relative to each other, and the folded part is the folded spine of the writing device, and the two panels 1 are made of acrylic or tempered glass or metal or ABS or ceramic;

[0048] The spine connection device 2 is at least one flexible sheet or hinge fixed to the folded spine. The spine connection device 2 is a long strip of flexible sheet, and extends and sticks between two panels 1 to form the folded spine;

[0049] The long strip of flexible sheet is adhered to the inner side of the folded spine;

[0050] It also includes a leveling card seat 6, which is clamped on the side of the panel 1 through a flat bottom groove 61. The side edges of a pair of panels 1 at at least one end of the spine of the two panels 1 are pressed against the bottom of the flat bottom groove 61, so that the two panels 1 are kept in the same straight line after unfolding.

[0051] At the same time, a connecting rope 44 is provided on the separated end panel surface of at least one panel 1, a card slot 45 corresponding to the connecting rope 44 is provided on the other panel 1, and a connecting hole 46 for the connecting rope 44 to pass through is provided on the panel 1, and the connecting rope 44 is a flexible or elastic connecting rope.

[0052] The connecting rope 44 of this embodiment passes through the card slot 45 and the connecting hole 46 to control the opening and closing of the device, and is combined into a triangular-shaped note board or a desk sign.

[0053] Example 4: Fig.12As shown, it is the same as Example 2, except that: the spine connecting device 2 is at least two long flexible sheets, the two long flexible sheets are fixedly connected on the extended central axis of the two flexible sheets, and the flexible sheets on both sides of the central axis form left and right installation grooves 21 for fixing the panel 1, and the panel 1 is glued or fixed in the installation groove 21 by screws.
