Description

Technical Field

[0001] This utility model belongs to the technical field of interactive whiteboard brackets for teaching, and in particular relates to a foldable interactive whiteboard auxiliary bracket. Background Technology

[0002] Interactive whiteboards, as an important carrier of modern educational technology, play a vital role in promoting teacher-student interaction and enhancing classroom participation in educational settings. Among them, handwriting-based interactive whiteboards are highly favored in professional fields that emphasize practical skills, such as fine arts, industrial design, and architectural drafting, due to their intuitive writing experience, low technical threshold, and flexible application characteristics.

[0003] Currently, the mainstream handwriting interactive whiteboard support structure uses traditional wooden supports with mortise and tenon joints or metal nails for fixing. While these have advantages such as low production cost and convenient processing, they also have significant drawbacks in practical applications. Firstly, the fixed frame structure results in a large space occupation for the equipment, which is particularly problematic when classroom space is limited and multiple sets of equipment need to be accommodated simultaneously, leading to low storage efficiency. Secondly, wooden materials are prone to deformation due to environmental humidity. When the humidity is high, displacement deviations may occur at the joints of the support, affecting the reliability of the support. Some supports also use folding legs, but the convenience and stability of folding structures are not ideal.

[0004] To address the aforementioned issues, this application proposes a foldable interactive whiteboard auxiliary support. Utility Model Content

[0005] The purpose of this invention is to provide a foldable interactive whiteboard auxiliary support, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a foldable interactive whiteboard auxiliary support, including a bearing seat and a support plate and support feet that are simultaneously hinged to the bearing seat. The bearing seat, support plate, and support feet are arranged in two symmetrical sets. A strut is fixed at the bottom of the bearing seat between the support plate and the support feet. The strut has a vertically sliding adapter seat. The adapter seat is movably connected to the support plate and support feet through a hinged connecting rod. The lifting and lowering of the adapter seat can cause the strut and support plate to unfold or fold simultaneously. Folding rods are hinged at the upper and lower ends of the two support plates. The folding of the folding rods can change the vertical distance between the two support plates, thereby allowing the two support plates to move closer to each other and fold.

[0008] Furthermore, the support rod is provided with a storage groove that can accommodate two connecting rods at the same time, and the upper end of the storage groove is connected to an adjustment groove that slides with the adapter seat.

[0009] Furthermore, the adjusting groove is provided with several locking grooves arranged along the sliding path of the adapter seat, and a locking block is hinged to the adapter seat by a torsion spring. The locking block engages with the locking groove by the torsion spring.

[0010] Furthermore, a handle is fixed to the locking block, the handle is located on the side of the bracket, and the handle is in contact with the side of the bracket when the locking block is engaged.

[0011] Furthermore, a vertically distributed and detachable backing plate and support plate are installed between the two support plates, and the interactive whiteboard is placed on the support plate and supported by the backing plate.

[0012] Furthermore, the side of the support plate is provided with several sets of insertion holes, and the connecting surfaces of the back plate and the support plate are fixed with pins. The pins are inserted into the insertion holes, and the pins are arranged in pairs.

[0013] Furthermore, the bottom of the support plate and support legs is flush with the bottom of the support rod after they are unfolded.

[0014] This utility model has the following beneficial effects:

[0015] This utility model links the support plate and support foot together through an adapter seat and connecting rod, and then locks them conveniently with a locking block. When the adapter seat is moved, it can drive the support plate and support foot to open and close simultaneously, thereby achieving a folding effect and making it easy to store. The folding rod set between the two support plates can fold the bracket again. When the back plate and support plate are installed with the support plate, they can ensure the overall strength of the bracket. After disassembly, they can be easily folded and stored. The spacing is flexible and the structure is reliable.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] 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.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a foldable interactive whiteboard auxiliary support, including a bearing 1 and a support plate 3 and a support foot 4 that are simultaneously hinged to the bearing 1. The bearing 1, support plate 3, and support foot 4 are arranged in two symmetrical sets. A support rod 2 is fixed at the bottom of the bearing 1 between the support plate 3 and the support foot 4. The support rod 2 is provided with a vertically sliding adapter 5. The adapter 5 is movably connected to the support plate 3 and the support foot 4 through a hinged connecting rod 6. The lifting and lowering of the adapter 5 can cause the support rod 2 and the support plate 3 to unfold or fold simultaneously. Folding rods 8 are hinged at the upper and lower ends of the two support plates 3. There are two folding rods 8 at each end. One end of the two folding rods 8 is respectively hinged to the symmetrical support plate 3, and the other end of the folding rods 8 is hinged to each other. The folding of the folding rods 8 can change the vertical distance between the two support plates 3, so that the two support plates 3 can move closer to each other and fold. The folding direction of the upper and lower folding rods 8 is inward.

[0027] Among them, the support rod 2 has a storage groove 21 that can accommodate two connecting rods 6 at the same time, and the upper end of the storage groove 21 is connected to an adjustment groove 22 that slides with the adapter 5.

[0028] The adjustment groove 22 is provided with several locking grooves 23 that are arranged along the sliding path of the adapter 5. Preferably, there are two locking grooves 23, which are used to lock the bracket when it is folded and unfolded by cooperating with the locking block 7. The adapter 5 is hinged with the locking block 7 by a torsion spring. The torsion spring provides a self-locking force to lock the locking block 7 and the locking groove 23. The torsion spring ensures the reliability of the connection between the locking block 7 and the locking groove 23 while making the operation convenient.

[0029] The locking block 7 is fixed with a handle 71, which is located on the side of the bracket. When the locking block 7 is engaged, the handle 71 is in contact with the side of the bracket. The outer handle 71 is easy to operate manually. At the same time, when the locking block 7 is locked, it can be in contact with the bracket to avoid unnecessary safety hazards caused by structural protrusion. The structure is also more compact.

[0030] Among them, two support plates 3 are provided with vertically distributed and detachable backing plates 9 and support plates 10. The interactive whiteboard is placed on the support plate 10 and supported by the backing plates 9. In order to enhance the stability of the interactive whiteboard, the number of backing plates 9 can be increased, and a screw-driven clamp can be set on the backing plates 9 and support plates 10 to clamp and position the interactive whiteboard.

[0031] The support plate 3 has several sets of insertion holes 31 on its side. The back plate 9 and the support plate 10 are fixed with pins 11 on their connecting surfaces with the support plate 3. The pins 11 are inserted into the insertion holes 31. The several sets of insertion holes 31 are distributed at different heights, which facilitates the height adjustment of the interactive whiteboard. At the same time, the combination of the insertion holes 31 and the pins 11 has the advantages of simple structure and convenient use. In order to ensure the connection strength between the support plate 3 and the back plate 9 and the support plate 10, the pins 11 are set in pairs to ensure that the folding rod 8 is always in a taut state after it is unfolded.

[0032] Among them, the bottom of the support plate 3 and the support foot 4 are flush with the bottom of the strut 2 after they are unfolded. When the support is unfolded, it is equivalent to forming 3 support points, and the strut 2 is also perpendicular to the ground, which has excellent structural strength.

[0033] Understandably, the one-click synchronous opening and closing of the support plate and support foot is achieved through the linkage of the adapter, connecting rod and locking block. Combined with the folding rod between the two support plates, the volume can be compressed by folding it twice. The modular back plate and support plate adopt a plug-in design, which enhances the overall rigidity during installation and makes it easy to store after disassembly, combining structural strength and portability.

[0034] One specific application of this embodiment is as follows: Figure 1The bracket is shown in its unfolded state. The placement height of the interactive whiteboard can be changed by changing the insertion position of the pin 11 and the socket 31. At this time, the folding rods 8 distributed vertically on the two support plates 3 are reliably supported by the back plate 9 and the support plate 10. The bottom of the support rod 2, support plate 3, and support foot 4 are simultaneously supported on the ground. The adapter seat 5 is located at the lower end of the adjustment groove 22. The locking block 7 is engaged in the locking groove 23 at the lower end by the torsion spring.

[0035] Folding: Disengage the locking block 7 from the lower locking groove 23 using the handle 71. At this time, the torsion spring connecting the locking block 7 and the adapter 5 is compressed, moving the adapter 5 upwards to the top of the adjusting groove 22. The upward-moving adapter 5 pulls the lower ends of the support rod 2 and support plate 3 inwards via the connecting rod 6, allowing the connecting rod 6 to fully enter the storage groove 21. At this time, the support plate 3 and support foot 4 are parallel. Under the action of the torsion spring, the locking block 7 is locked to the locking groove 23. Remove the backing plate 9 and support plate 10 from the support plate 3. The pin 11 then disengages from the insertion hole 31. Bring the two support plates 3 closer together and fold both sets of folding rods 8 inwards. Figure 3 To achieve the final storage state of the bracket, use straps, cable ties, or similar bindings.
