Description

Technical Field

[0001] This utility model relates to the field of training whiteboard technology, specifically a foldable and retractable training whiteboard. Background Technology

[0002] A training whiteboard is a writing tool used in teaching, meeting discussions, and personal and family note-taking. Similar to a blackboard, it can be repeatedly erased and rewritten. Training whiteboards come in various sizes, from small home whiteboards to large whiteboards used in conference rooms or classrooms. They can also be categorized by material, such as metallic paint, enamel, PET, and glass.

[0003] When conducting teaching training or meeting discussions, it is necessary to write relevant content on the training whiteboard. For easy storage, existing training whiteboards are generally designed to be foldable. When needed, it is necessary to first remove the limiting of a set of supports, allowing them to rotate and separate from the whiteboard, and then unfold the supports to form a V-shape to support the whiteboard. This type of whiteboard requires multiple steps to fold and unfold, making it inconvenient to quickly fold and store or unfold for use. Utility Model Content

[0004] The purpose of this invention is to provide a foldable and retractable training whiteboard to solve the problem mentioned in the background art that existing training whiteboards are not convenient to fold and store.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable training whiteboard, comprising: a whiteboard body and a folding mechanism, wherein a connecting frame is movably connected to one side of the whiteboard body via a pivot, and two sets of supports are movably connected inside the connecting frame via a pivot.

[0006] The connecting frame is internally equipped with a folding mechanism for folding the bracket. The folding mechanism includes a pressing block that is connected through the connecting frame. One end of the pressing block is fixed to the whiteboard body. A pressure plate is provided at the bottom of the pressing block. The bottom of the pressure plate abuts against a connecting block a. One end of the connecting block a is fixed to the bracket. One end of the connecting frame is equipped with a limiting mechanism. The limiting mechanism includes a connecting plate that is movably connected to the connecting frame via a rotating shaft. A locking rod is slidably connected inside the connecting plate.

[0007] Preferably, sliders are fixedly connected to both sides of the pressure plate, the outer side of the sliders is slidably connected to the connecting frame, and a tension spring a is fixedly connected to one side of the bracket.

[0008] Preferably, one end of the tension spring a is fixed to the fixing block, and one side of the fixing block is fixed to the connecting frame.

[0009] Preferably, the other side of the bracket abuts against a limiting block, one side of the limiting block is fixed to the connecting frame, and the limiting block is wedge-shaped.

[0010] Preferably, the connecting block a has an arc shape, one end of the pressing block is arc-shaped, and a tension spring b is sleeved on the outside of the clamping rod.

[0011] Preferably, one end of the tension spring b is fixed to the connecting plate, and the other end of the tension spring b is fixedly connected to the connecting block b.

[0012] Preferably, the side of the connecting block b near the tension spring b is fixed to the locking rod, a locking groove is provided on one side of the connecting frame, and the locking groove engages with the locking rod, and one side of the connecting plate is fixed to the whiteboard body.

[0013] Compared with existing technologies, the beneficial effects of this foldable training whiteboard are as follows: When storing the foldable training whiteboard, pulling the connecting block b causes the two sets of latches on one side to disengage from the connecting frame. After the latches disengage from the connecting frame, the connecting frame can be rotated to fold up. As the connecting frame rotates, the pressing block disengages from the inside of the connecting frame and no longer presses the pressure plate. At this time, the tension spring a will reset and pull the bracket to rotate, making it parallel to the connecting frame, thus completing the automatic folding and storage of the two sets of brackets. After the connecting frame rotates 180°, the connecting block b can be released. At this time, the tension spring b will pull the connecting block b to reset, causing the two sets of latches on one side to engage with the slots again, thus limiting the connection frame. At this time, the training whiteboard will be in a fully folded state. Thus, the above operation makes it easy to fold and store the whiteboard. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a foldable and storable training whiteboard, comprising: a whiteboard body 1 and a folding mechanism 4. A connecting frame 2 is movably connected to one side of the whiteboard body 1 via a pivot, and two sets of supports 3 are movably connected inside the connecting frame 2 via pivots.

[0021] The connecting frame 2 is provided with a folding mechanism 4 for folding the bracket 3. The folding mechanism 4 includes a pressing block 401 that is connected through the connecting frame 2. One end of the pressing block 401 is fixed to the whiteboard body 1. A pressure plate 402 is provided at the bottom of the pressing block 401. The bottom of the pressure plate 402 abuts against a connecting block a404. One end of the connecting block a404 is fixed to the bracket 3. A limiting mechanism 5 is provided at one end of the connecting frame 2. The limiting mechanism 5 includes a connecting plate 501 that is movably connected to the connecting frame 2 through a rotating shaft. A locking rod 502 is slidably connected inside the connecting plate 501.

[0022] Both sides of the pressure plate 402 are fixedly connected to sliders 403. The outer side of the sliders 403 is slidably connected to the connecting frame 2. One side of the bracket 3 is fixedly connected to a tension spring a405. One end of the tension spring a405 is fixed to a fixing block 406, and one side of the fixing block 406 is fixed to the connecting frame 2. The other side of the bracket 3 abuts against a limit block 407. One side of the limit block 407 is fixed to the connecting frame 2. The limit block 407 is wedge-shaped. The connecting block a404 is arc-shaped. One end of the pressing block 401 is arc-shaped. A tension spring b503 is sleeved on the outer side of the clamping rod 502. The bracket 3 forms a rotating structure with the connecting frame 2 via a rotating shaft; one end of the tension spring b503 is fixed to the connecting plate 501, and the other end of the tension spring b503 is fixedly connected to the connecting block b504; the side of the connecting block b504 near the tension spring b503 is fixed to the locking rod 502; a locking groove 505 is provided on one side of the connecting frame 2, and the locking groove 505 engages with the locking rod 502; one side of the connecting plate 501 is fixed to the whiteboard body 1; a sliding groove matching the locking rod 502 is provided inside the connecting plate 501; the locking rod 502 and the connecting plate 501 form a sliding structure.

[0023] In practical implementation, when the foldable training whiteboard is stored, the connecting block b504 can be pulled to move it. The connecting block b504 will drive the two sets of locking rods 502 on one side to move, causing them to disengage from the two sets of locking slots 505 on one side of the connecting frame 2. When the connecting block b504 moves, it will stretch the tension spring b503. After the locking rods 502 disengage from the connecting frame 2, the connecting frame 2 can be rotated and folded up. As the connecting frame 2 rotates, the pressing block 401 will disengage from the interior of the connecting frame 2 and will no longer exert pressure on the pressure plate. When 402 is pressed, the tension spring a405 will reset and pull the bracket 3 to rotate, making it parallel to the connecting frame 2, thus completing the automatic folding and storage of the two sets of brackets 3. After the connecting frame 2 rotates 180°, the connecting block b504 can be released. At this time, the tension spring b503 will pull the connecting block b504 to reset, so that the two sets of latches 502 on one side will engage with the latches 505 again, thus limiting the connecting frame 2. At this time, the training whiteboard will be in a fully folded state, which can save storage space.

[0024] When the training whiteboard needs to be unfolded, the limiting position of the connecting frame 2 is removed, and then the connecting frame 2 is rotated to unfold. When the squeezing block 401 penetrates the connecting frame 2, the squeezing block 401 will squeeze the pressure plate 402, causing it to move down and squeeze the two sets of connecting blocks a404. The connecting blocks a404 will drive the two sets of brackets 3 to rotate and unfold. When the bracket 3 rotates and contacts the inclined surface of the limiting block 407, it will stop rotating. At this time, the connecting frame 2 can be limited by the limiting mechanism 5 to complete the unfolding of the whiteboard. In this way, the whiteboard can be easily folded and stored.

[0025] In summary: When using the foldable training whiteboard, first unfold the support 3 at the bottom of the whiteboard body 1 to support the whiteboard body 1, and then write content on the whiteboard body 1 with a marker. The content not described in detail in this instruction belongs to the prior art known to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
