The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] The utility model discloses a portable sticky writing board 10, which aims to break the existing writing tool using a combination of a board and accessories, and further provide a film paper that can replace the traditional board, thereby solving the problems of poor portability and cumbersome cleaning of the traditional board. Figure 1 As shown, the portable adhesive writing board 10 includes a protective shell 100 and a writing film paper 200 matched with the protective shell 100 .

[0036] Among them, Figure 1 and Figure 2 As shown, the protective housing 100 includes: a main body 110, a first end cover 120 and a second end cover 130. The main body 110 is a hollow cylindrical structure with two ends open. The first end cover 120 and the second end cover 130 are respectively arranged at two ends of the main body 110. The main body 110 forms a receiving chamber 111 inside, and the writing film paper 200 is rotatably accommodated in the receiving chamber 111. The main body 110 is provided with a peeling opening 112, and the writing film paper 200 is pulled out from the peeling opening 112.

[0037] Moreover, if Figure 3 and Figure 4As shown, the writing film paper 200 includes an adhesive portion 210 and a writing portion 220 connected to the adhesive portion 210, and the writing portion 220 is an expandable multi-layer folding structure (such as Figure 4 shown).

[0038] In this embodiment, if Figure 5 and Figure 6 As shown, the protective housing 100 is provided with an accessory 300, and the accessory 300 includes a brush 310 and a cleaning block 320. The brush 310 is used to write on the writing part 220 of the writing film paper 200, and the cleaning block 320 is used to erase the handwriting on the writing part 220.

[0039] Preferably, Figure 2 and Figure 5 As shown, a positioning column 121 is provided on the first end cover 120, and the positioning column 121 is located in the accommodation chamber 111. The writing film paper 200 accommodated in the accommodation chamber 111 is in a roll-shaped structure, and the writing film paper 200 in a roll-shaped structure is sleeved on the positioning column 121. The positioning column 121 has a limiting effect on the writing film paper 200. When the user extracts the writing film paper 200, the writing film paper 200 in a roll-shaped structure will rotate with the positioning column 121 as the axis.

[0040] The portable sticky writing board 10 of the utility model is mainly used to meet the user's writing display needs anytime and anywhere. Its main principle is as follows: when going out, the user only needs to carry the product in a backpack; when it is needed, such as Figure 7 As shown, the user holds the protective housing 100 with one hand and pulls the writing film 200 out of the peeling opening 112 with the other hand. Since the writing film 200 has an adhesive portion 210, the user only needs to stick the adhesive portion 210 on the wall (or the surface of a cabinet, a glass plate, etc.), and then cut the writing film 200, so that part of the writing film 200 can be attached to the wall quickly and conveniently; then, the user unfolds the multi-layer folded writing portion 220 (as shown in FIG. Figure 8 As shown), a large-sized writing film paper 200 located on the wall can be obtained, that is, the writing film paper 200 and the wall can cooperate to form a role similar to a traditional writing board, so that the user can use the brush 310 to complete the writing display on the writing film paper 200; when it is not needed, the user can peel off the writing film paper 200 on the wall.

[0041] It should be emphasized that the writing film paper 200 of the utility model has an adhesive portion 210 and a writing portion 220. The adhesive portion 210 is conducive to conveniently posting the writing film paper 200 on the wall, so that no external tape or glue is required, and convenient operation is achieved. Moreover, the writing portion 220 is an expandable multi-layer folding structure. When the writing film paper 200 is posted on the wall, the user can unfold the multi-layer writing portion 220 to expand the area of ​​the writing portion 220. In this way, when carrying, the writing portion 220 of the multi-layer folding structure can reduce the overall size of the writing film paper 200 as much as possible, thereby improving the portability of the product; and when in use, the writing portion 220 of the multi-layer folding structure can be unfolded to obtain a larger writing area, so that it is convenient for users to display.

[0042] It is worth noting that, compared with the prior art, the portable adhesive writing board 10 of the present invention has the following features and effects as a whole:

[0043] First, it is easy to carry around. The utility model adopts the writing film paper 200 to replace the traditional board. When using it, the user only needs to attach the writing film paper 200 to the wall to form a "traditional board" for writing, thereby solving the technical problem that the traditional board is not easy to carry.

[0044] Second, it is easy to clean. After the writing display is completed, the traditional board in the prior art needs to be reused, so it needs to be wiped for the next use; while the writing film paper 200 of the utility model only needs to be peeled off to restore the wall after the display is completed;

[0045] Thirdly, it is convenient to collect or repeatedly display. When the user finishes writing and displaying at a certain place, he only needs to peel off the writing film paper 200 and fold it for collection. This also makes it convenient for the user to carry it to another place and then post it again for display.

[0046] Fourthly, compared with the traditional board, the price is relatively high. If the user needs to place the board in multiple rooms, it will cause a large cost burden. However, by using the product of the utility model, the writing film paper 200 can be arranged in multiple rooms at a low cost, thereby saving costs.

[0047] Fifth, the protective shell 100 not only plays a protective role, but also facilitates the extraction of the writing film paper 200 during use. Specifically, when carried in a backpack, the protective shell 100 can protect the writing film paper 200 from being squeezed and wrinkled, and the writing film paper 200 is not easy to spread out when contained in the accommodation chamber 111; when extracting the writing film paper 200, if there is no protective shell 100, the user needs to continuously rotate the roll-shaped writing film paper 200, but after using the protective shell 100, the user only needs to hold the protective shell 100 with one hand and pull the free end of the writing film paper 200 with the other hand, and the writing film paper 200 can be smoothly extracted (the roll-shaped writing film paper 200 rotates in the accommodation chamber 111 by itself).

[0048] In this embodiment, in order to facilitate carrying the accessory 300, the accessory 300 is combined with the protective housing 100 in the utility model. Specifically, the positioning column 121 is provided with a receiving groove 122 (such as Figure 6 As shown in FIG. 1 , the paintbrush 310 is detachably received in the receiving groove 122, and the opening of the receiving groove 122 faces the outside of the first end cover 120. When carried, the paintbrush 310 is inserted into the receiving groove 122 of the positioning column 121, so that the space can be fully utilized, thereby reducing the overall size of the product; when it is needed, the user can just pull out the paintbrush 310, so that the paintbrush 310 does not need to be carried separately, which provides convenience for the user.

[0049] Preferably, Figure 6 and Fig. 9 As shown, the first end cover 120 is provided with an easy-access groove 123, which is located at the opening of the receiving groove 122. On the outside of the first end cover 120, the easy-access groove 123 is a groove structure; on the inside of the first end cover 120, the groove wall of the easy-access groove 123 is a boss structure. In this way, when taking out the paintbrush 310, the groove structure of the easy-access groove 123 facilitates the user to insert his finger into and clamp the paintbrush 310; and inside the accommodating chamber 111, the boss structure has a guiding function, which can make the axis of the writing film paper 200 as close to the axis of the positioning column 121 as possible.

[0050] Furthermore, in this embodiment, Fig. 9 and Figure 5 As shown, a clamping groove 131 is provided on the outer side of the second end cover 130, and the cleaning block 320 is detachably received in the clamping groove 131. This is convenient for carrying and also convenient for users to take when needed.

[0051] In another embodiment, the cleaning block 320 can also be disposed on the outer wall of the main body 110 (not shown), so that when it is needed, the user directly holds the protective shell 100 and brings the cleaning block 320 on the main body 110 close to the writing film paper 200 to perform the wiping operation.

[0052] Furthermore, in order to solve the problem of cutting the writing film paper 200 and achieve quick and convenient cutting, the utility model also provides two cutting solutions, which are as follows:

[0053] Option 1:

[0054] like Figure 5 As shown, the main body 110 is provided with a knife groove 113 and a slider knife 114, the knife groove 113 is provided on the outer wall of the main body 110, and there is a certain distance between the knife groove 113 and the stripping opening 112. The slider knife 114 is slidably provided on the knife groove 113, and the slider knife 114 is used to cut the writing film paper 200.

[0055] When cutting, the user needs to move the writing film paper 200 around the knife groove 113, and then push the slider knife 114 to move, so that the slider knife 114 contacts and cuts the writing film paper 200 at the knife groove 113, thus completing the cutting operation.

[0056] It should be noted that due to the certain distance between the knife groove 113 and the stripping opening 112, this means that after being cut by the slider knife 114, a small portion of the writing film paper 200 still remains outside the protective shell 100, which makes it convenient for the user to continue to extract the writing film paper 200, thereby avoiding the problem of having to deduct the writing film paper 200 from the entire roll of material each time it is extracted.

[0057] Preferably, Figure 5 and Figure 6 As shown, the second end cover 130 is further provided with an avoidance groove 132, the position of the avoidance groove 132 corresponds to the position of the knife groove 113, and the slider cutter 114 can slide into the avoidance groove 132. Initially, the slider cutter 114 is in the avoidance groove 132, so that when the writing film paper 200 bypasses the knife groove 113, the slider cutter 114 in the avoidance groove 132 will not interfere with the writing film paper 200; after the writing film paper 200 bypasses the knife groove 113, the slider cutter 114 slides into the knife groove 113 again, thereby cutting the writing film paper 200.

[0058] Option 2:

[0059] like Fig.10 As shown, the writing film paper 200 is provided with a plurality of pinhole cutting lines 201, which are formed by a plurality of pinholes arranged neatly, and the distances between adjacent pinhole cutting lines 201 are the same. In this way, when in use, after the user extracts the writing film paper 200, he only needs to tear it hard along the pinhole cutting lines 201 to tear the writing film paper 200, thereby realizing convenient access to the writing film paper 200.

[0060] In summary, the portable adhesive writing board 10 of the present invention is convenient for users to carry and meet the users' writing display needs anytime and anywhere, and can also be easily cleared to reduce the users' usage burden.

[0061] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
