Description

Technical Field

[0001] This utility model relates to the field of message board technology, and more specifically, to a retractable message board. Background Technology

[0002] A message board is a device for people to write messages. Currently, to avoid waste and ensure reusability, the writable parts of message boards on the market are made of erasable materials. However, existing message boards on the market are all made of rigid materials, meaning they cannot be rolled up or folded. As a result, when message boards need to be carried or stored, they take up a lot of space and are bulky, making them inconvenient to carry or store. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a retractable message board, which has the advantages of being easy to carry or store, and also has the advantage of being able to store items.

[0004] This utility model provides a retractable message board, including a support assembly and erasable paper; the support assembly includes a take-up roller and support seats connected to both ends of the take-up roller, one end of the erasable paper in the length direction is connected to the take-up roller, and the take-up roller is used to take up the erasable paper; a connector is provided on the rear side of the support seat, and the support seat is connected to the support body through the connector; the take-up roller has a storage cavity extending in its axial direction inside, one end of the storage cavity is open and the open end of the storage cavity extends to the outer end of one of the support seats, and the support assembly also includes an end cap, which is detachably connected to the open end of the storage cavity and is used to close the storage cavity.

[0005] By adopting the above structure, this utility model enables the support component to rewind the erasable paper when the message board is not in use, thereby reducing the size and volume of the message board, which makes it convenient to carry or store. Furthermore, by setting a storage cavity inside the rewind roller, the storage cavity can store items such as writing pens, giving the message board a multi-functional advantage.

[0006] In one possible implementation, the outer wall of the take-up roller is provided with a plurality of interposed blocks spaced apart along the axial direction of the take-up roller. These interposed blocks are used to engage with the insertion holes located at the ends of the erasable paper. The support assembly also includes an arc-shaped pressure plate disposed on the outer side of the take-up roller in the radial direction. One side of the pressure plate is rotatably connected to support seats located on both sides of the take-up roller, and the other side of the pressure plate abuts against the outer ends of the interposed blocks and remains in close contact with them. With this structure, each insertion hole at one end of the erasable paper is matched with an interposed block at a corresponding position. With the interlocking mechanism in place, and after the pressure plate rotates relative to the support base and the other side of the pressure plate abuts against the outer ends of several insert blocks, it can prevent the insert holes on the erasable paper from detaching from the insert blocks, thus achieving a reliable connection between the end of the erasable paper along its length and the support assembly. Furthermore, when the pressure plate is rotated in the opposite direction, the other side of the pressure plate can be released from its tight contact with the insert blocks. At this time, the end of the erasable paper along its length can detach from the insert blocks, thus achieving the separation of the erasable paper from the support assembly. This facilitates the replacement of the erasable paper after it is damaged or aged.

[0007] In one possible implementation, a plurality of protrusions spaced apart along the axial direction of the take-up roller are provided on one side of the pressure plate. When the pressure plate rotates relative to the support base so that the other side of the pressure plate abuts against the outer ends of a plurality of inserts, the plurality of protrusions are used to press against the outer wall of the take-up roller to restrict the free rotation of the pressure plate. With this structure, when the pressure plate rotates relative to the support base so that the other side of the pressure plate abuts against the outer ends of a plurality of inserts, the plurality of protrusions can press against the outer wall of the take-up roller, thereby achieving the purpose of tension between the pressure plate and the take-up roller, that is, restricting the free rotation of the pressure plate, so that the other side of the pressure plate can reliably abut against the outer ends of a plurality of inserts and maintain a tight abutment with the inserts, that is, preventing the end of the erasable paper in the length direction from detaching from the support assembly.

[0008] In one possible implementation, the two protrusions at both ends of the pressure plate are rotatably connected to the corresponding support seats via a pivot. With this structure, the pivot can reliably connect one side of the pressure plate to the two support seats.

[0009] In one possible implementation, the connector is self-adhesive, and the support base is bonded to the support body by self-adhesive. With this structure, the support base can be reliably and conveniently bonded to the support body, that is, it is easy to bond the support component to the support body, such as to the glass or wall. Moreover, the self-adhesive can be used multiple times, that is, the self-adhesive can be reused so that the support component can be repeatedly bonded to different supports.

[0010] In one possible implementation, two support components are provided, with each end of the erasable paper along its length connected to a winding roller of one of the support components. With the two support components, after the erasable paper is unfolded and both support components are connected to the support body, the two support components can fix both ends of the erasable paper along its length, thus facilitating writing on the erasable paper and effectively preventing movement of the erasable paper. Alternatively, after the upper support component is pre-connected to the support body, and the lower support component partially winds up the erasable paper and is subsequently connected to the support body, the length of the unfolded portion of the erasable paper can be freely adjusted to meet the user's needs.

[0011] In one possible implementation, after the two support components have finished winding the erasable paper and are abutting each other, the two support components are locked together by a locking structure. With the locking structure, after the two support components have finished winding the erasable paper, they can be locked together by the locking structure, so that the erasable paper can be reliably kept in the wound state to prevent the erasable paper from unraveling, which can bring convenience to the storage and retrieval of the retractable message board.

[0012] In one possible implementation, the locking structure includes two locking units, located on opposite sides of the two support components. Each locking unit includes an arc-shaped locking groove and an arc-shaped locking block. The end cap is rotatably connected to the support base. The locking block is located on the inner wall of the end cap, and the locking groove is located on the outer wall of the support base on the side away from the end cap. When the two support components abut against each other and the end cap is rotated to allow the locking block to slide into the locking groove, the two support components are locked together. With this structure, when the two support components roll up the erasable paper and the end cap is rotated to allow the locking block to slide into the locking groove, the two support components can be locked together, thereby reliably keeping the erasable paper in a rolled-up state to prevent it from unraveling, thus facilitating the storage and organization of the retractable message board.

[0013] In one possible implementation, an annular insertion part is provided on the inner wall of the end cap, which is rotatably inserted into the opening end of the storage cavity. With this structure, after the insertion part is engaged with the opening end of the storage cavity, the end cap can be easily detached and the storage cavity can be reliably sealed, while also ensuring the rotatable connection between the end cap and the support base.

[0014] In one possible implementation, a lug is provided on the outer edge of the end cap, and a locking block is disposed on the inner wall of the lug. With this structure, when the end cap needs to be rotated, a finger can be pressed against the lug and pushed to rotate the end cap, thereby facilitating the rotation of the end cap and making it easier for the locking block to slide into or out of the locking groove, thus making it convenient to lock and unlock the two support components.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] See Figures 1-7 As shown in the figure, this application discloses a retractable message board, including a support assembly 1 and an erasable writing paper 2. The support assembly 1 includes a take-up roller 11 and support seats 12 connected to both ends of the take-up roller 11. One end of the erasable writing paper 2 in the length direction is connected to the take-up roller 11, and the take-up roller 11 is used to take up the erasable writing paper 2. A connector 13 is provided on the rear side of the support seat 12, and the support seat 12 is connected to the support body through the connector 13. The take-up roller 11 has a storage cavity 111 extending in its axial direction inside. One end of the storage cavity 111 is open and the open end of the storage cavity 111 extends to the outer end of one of the support seats 12. The support assembly 1 also includes an end cap 14, which is detachably connected to the open end of the storage cavity 111 and is used to close the storage cavity 111. The erasable writing paper mentioned above is the existing technology on the market, so it will not be described in detail here.

[0021] The outer wall of the take-up roller 11 is provided with a plurality of insert blocks 112 spaced apart along the axial direction of the take-up roller 11. The plurality of insert blocks 112 are used to engage with the insertion holes located at the ends of the erasable paper 2. The support assembly 1 also includes an arc-shaped pressure plate 15, which is disposed on the outer side of the take-up roller 11 in the radial direction. One side of the pressure plate 15 is rotatably connected to the support seats 12 located on both sides of the take-up roller 11, and the other side of the pressure plate 15 abuts against the outer ends of the plurality of insert blocks 112 and maintains a tight abutment with the insert blocks 112. With this structure, each insertion hole located at one end of the erasable paper engages with the corresponding insert block, and the pressure plate rotates relative to the support seat. When the pressure plate is rotated so that the other side of the pressure plate abuts against the outer ends of several insert blocks, it can prevent the inserts on the erasable paper from detaching from the insert blocks, thus ensuring a reliable connection between the longitudinal end of the erasable paper and the support assembly. Furthermore, when the pressure plate is rotated in the opposite direction, the other side of the pressure plate can release its tight contact with the insert blocks. At this time, the longitudinal end of the erasable paper can detach from the insert blocks, thus separating the erasable paper from the support assembly. This facilitates the replacement of the erasable paper after it is damaged or aged. In addition, it should be noted that when the take-up roller in the support assembly takes up the erasable paper, the erasable paper is wrapped around the take-up roller and the pressure plate.

[0022] A plurality of protrusions 151 are provided on one side of the pressure plate 15, which are spaced apart along the axial direction of the take-up roller 11. When the pressure plate 15 rotates relative to the support base 12 so that the other side of the pressure plate 15 abuts against the outer ends of a plurality of inserts 112, the plurality of protrusions 151 are used to press against the outer wall of the take-up roller 11 to restrict the free rotation of the pressure plate 15. With this structure, when the pressure plate rotates relative to the support base so that the other side of the pressure plate abuts against the outer ends of a plurality of inserts, the plurality of protrusions can press against the outer wall of the take-up roller, thereby achieving the purpose of tension between the pressure plate and the take-up roller, that is, restricting the free rotation of the pressure plate, so that the other side of the pressure plate can reliably abut against the outer ends of a plurality of inserts and maintain a tight abutment with the inserts, that is, preventing the end of the erasable paper in the length direction from detaching from the support assembly.

[0023] Two protrusions 151 located at both ends of the pressure plate 15 are rotatably connected to the corresponding support base 12 via a pivot. With this structure, under the action of the pivot, one side of the pressure plate can be reliably rotatably connected to the two support bases.

[0024] The connector 13 is self-adhesive, and the support base 12 is bonded to the support body by self-adhesive. With this structure, the support base can be reliably and conveniently bonded to the support body, that is, it is easy to bond the support components to the support body, such as to the glass or wall. Moreover, the self-adhesive can be used multiple times, that is, the self-adhesive can be reused, so that the support can be repeatedly bonded to different supports. This self-adhesive is the existing technology on the market, so it will not be described in detail here.

[0025] There are two support components 1. The two ends of the erasable paper 2 along its length are respectively connected to the winding roller 11 of one of the support components 1. With the two support components, after the erasable paper is unfolded and both support components are connected to the support body, the two support components can fix the two ends of the erasable paper along its length, so as to facilitate the user to write on the erasable paper and effectively prevent the erasable paper from moving. Alternatively, after the upper support component is pre-connected to the support body and the lower support component is wound up and then connected to the support body, the length of the unfolded erasable paper can be freely adjusted to meet the user's needs.

[0026] After the two support components 1 finish winding the erasable paper 2 and abut against each other, the two support components 1 are locked together by a locking structure. With the locking structure, after the two support components finish winding the erasable paper, the two support components can be locked together by the locking structure, so that the erasable paper can be reliably kept in the wound state to prevent the erasable paper from unraveling, which can bring convenience to the storage and retrieval of the retractable message board.

[0027] Each locking structure includes two locking units, located on opposite sides of the two support components 1. Each locking unit includes an arc-shaped locking groove 16 and an arc-shaped locking block 141. The end cap 14 is rotatably connected to the support base 12. The locking block 141 is disposed on the inner wall of the end cap 14, and the locking groove 16 is disposed on the outer wall of the support base 12 on the side away from the end cap 14. When the two support components 1 abut against each other and the end cap 14 is rotated to allow the locking block 141 to slide into the locking groove 16, the two support components 1 are locked together. By adopting this structure, the two... The support components wind up the erasable paper, and after the end cap is rotated to allow the locking block to slide into the locking groove, the two support components can be locked together, thereby reliably keeping the erasable paper in a wound state to prevent it from unraveling, which facilitates the storage and organization of the retractable message board. In addition, the two support components are set to be centrally symmetrical about the erasable paper, so two identical support components can be used, which facilitates the production of the support components and reduces the development and production costs of the support components.

[0028] An annular insertion part 142 is provided on the inner wall of the end cap 14. The insertion part 142 is rotatably inserted into the opening end of the storage cavity 111. With this structure, after the insertion part is inserted into the opening end of the storage cavity, the end cap can be easily detached and the storage cavity can be reliably closed. At the same time, the rotational connection between the end cap and the support base can be guaranteed.

[0029] The outer edge of the end cap 14 is provided with a lug 143, and the locking block 141 is provided on the inner wall of the lug 143. With this structure, when the end cap needs to be rotated, the finger can be pressed against the lug and pushed to make the end cap rotate, which makes it easy to rotate the end cap, and also makes it easy for the locking block to slide into or out of the locking groove, thus making it convenient to lock and unlock the two support components.

[0030] When the retractable message board uses a structure with only a single support component, the erasable paper can be unfolded and the support component can be connected to the support body. At this time, the erasable paper is in a suspended state, and users can write messages on the erasable paper. When the retractable message board needs to be stored, the support component can be removed from the support body, and the erasable paper can be wrapped around the take-up roller and pressure plate.

[0031] When the retractable message board adopts a structure with two support components, the erasable paper can be unfolded, and the two support components can be connected to the support body. After the two support components are connected to the support body, the erasable paper can be tensioned and fixed, thus preventing the erasable paper from moving freely. This makes it convenient for users to write messages on the erasable paper. Alternatively, after the upper support component is pre-connected to the support body, and the lower support component rolls up the erasable paper and is then connected to the support body, the length of the unfolded erasable paper can be freely adjusted to meet the user's needs. When the retractable message board needs to be stored, the erasable paper can be rolled up by the two support components, and the two support components can lock each other after rolling up the erasable paper, thus preventing the erasable paper from unraveling and ensuring the reliability of the erasable paper rolling.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
