Description

Technical Field

[0001] The utility model belongs to the technical field of teaching tools, and in particular relates to a writing board for projection and writing. Background Art

[0002] A whiteboard is a writing surface typically made of white metal. Similar in function to a blackboard, it's a rewritable writing tool, often used for teaching, meetings, or personal and family note-taking. However, current whiteboards offer limited functionality, serving only as a writing surface and failing to meet the diverse needs of users. Furthermore, many businesses install projectors, which require the purchase of additional projection screens, increasing costs. Furthermore, existing projection screens are fixed in position after installation and cannot be moved to different locations for projection. Therefore, designing a writing board that can accommodate both writing and projection is a pressing need. Utility Model Content

[0003] (1) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the present invention is to provide a dual-purpose writing tablet for projection and writing, so as to solve the technical problem that the existing writing tablets have a single function, only have writing functions, and cannot meet the needs of users.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A dual-purpose writing board for projection and writing comprises a vertical stand and a whiteboard body mounted on the stand, wherein one side of the whiteboard body is a glossy panel for writing, and the other side is a matte panel for projecting a projection image, and further comprises a hook assembly mounted on the top of the stand for hanging an external hanging board;

[0008] The present application sets one side of the whiteboard body as a glossy panel and the other side as a matte panel. When writing is needed, writing can be done on the glossy panel to ensure the smoothness of writing. If projection is needed, the matte panel is matched with the projector, and the light emitted by the projector can be directly projected onto the matte panel to form a projection picture. Since the surface of the matte panel is non-reflective, a clearer projection picture can be formed. The writing board of the present application can be used for both writing and projection. Users do not need to purchase a projection screen separately, saving purchase costs. In addition, the handwriting board can be moved to any position for projection, which is easy to use. When the current whiteboard body is full but the content does not want to be erased immediately, it can be hung on the hanging board through the hook component and continue to write on the hanging board. Or when certain content needs to be displayed, the hanging board with the content can be directly hung on the hook component for display.

[0009] In some embodiments, the invention further comprises: a placement rack disposed below the whiteboard body and having two ends connected to two sides of the bracket;

[0010] The placement rack can not only be used to place writing pens, but also can support the lower end of the hanging board when the height and weight of the hanging board are high and heavy, so as to prevent the hook component from being subjected to excessive force and easily deformed.

[0011] In some embodiments, both ends of the placement rack are slidably engaged with the bracket and can be locked to a predetermined height of the bracket;

[0012] The height of the shelf can be adjusted to suit hanging boards of different heights.

[0013] In some embodiments, guide rails are vertically provided on both sides of the bracket, and slots are provided at both ends of the placement rack to engage with the corresponding guide rails;

[0014] The placement rack slides with the guide rail through the card slot to ensure the direction of up and down sliding, and avoid the position of the placement rack being offset when fixed, which leads to the inability to stably support the hanging board.

[0015] In some embodiments, it also includes: a locking component that is movably arranged to abut against the bracket when both ends of the placement rack are extended to lock the placement rack to a predetermined height of the bracket.

[0016] In some embodiments, two symmetrical locking walls are formed on each side of the bracket along its height, and each locking assembly includes: two locking screws that pass through the end of the placement rack and are threadedly engaged with the end of the placement rack, wherein each locking screw can move toward the corresponding locking wall and the end abuts against the locking wall to lock the placement rack to a predetermined height of the bracket.

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] The utility model provides a dual-purpose writing board for projection and writing, comprising: a vertically arranged bracket 1 and a whiteboard body 2 arranged on the bracket 1, wherein one side of the whiteboard body 2 is a bright panel for writing, and the other side is a matte panel for projecting to form a projection image, and further comprising: a hook component 3 arranged on the top of the bracket 1 for hanging an external hanging board 4.

[0024] Specifically, matte paint may be coated on one side of the whiteboard body 2 to form a matte panel.

[0025] Preferably, particles may be added to the matte panel to form a diffuse reflection layer, so that the projected image is clearer and has a better texture.

[0026] Specifically, the hook assembly 3 includes: a fixing member 301 and a hook 302 connected to the fixing member 301 , and the hook 302 can hang the hanging plate 4 .

[0027] Preferably, a placement rack 5 can be set under the whiteboard body 2, and the two ends of the placement rack 5 are respectively connected to the two sides of the bracket 1. On the one hand, the placement rack 5 can be used to place writing pens, and on the other hand, it can support the lower end of the hanging board 4 when the height and weight of the hanging board 4 are high.

[0028] Preferably, both ends of the placement rack 5 can be configured to slide with the bracket 1 and be locked to a predetermined height of the bracket 1, so as to facilitate adjustment of the height of the placement rack 5 to accommodate hanging boards 4 of different sizes.

[0029] Specifically, a vertical guide rail 6 can be provided on both sides of the bracket 1 , and slots that engage with the corresponding guide rail 6 are provided at both ends of the placement rack 5 , so that the placement rack 5 can slide up and down along the guide rail 6 .

[0030] Specifically, two locking walls 101 are formed on the side of the bracket 1, and locking components are provided at both ends of the placement rack 5. Specifically, each locking component includes: a locking screw 7 that is passed through the end of the placement rack 5 and is threadedly engaged with the end of the placement rack 5. When the height of the placement rack 5 needs to be adjusted, the locking screw 7 is loosened and the position of the placement rack 5 is slid up and down. When the placement rack 5 slides to a suitable position, the locking screw 7 is tightened so that the end of the locking screw 7 abuts against the locking wall 101 to lock the placement rack 5.
