Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, specifically to an adjustable writing device for teaching. Background Technology

[0002] A whiteboard is a writing surface, usually made of white metal. Similar to a blackboard, it is an erasable writing tool, commonly used for teaching, meeting discussions, or personal and family note-taking.

[0003] Unlike blackboards, whiteboards are more advantageous due to their smaller size and portability, allowing users to write at any time without being fixed in one place. However, the drawback of existing portable whiteboards is that they are prone to glare. To solve the problem of glare causing blindness, current technology requires a flipping mechanism to prevent glare. However, because of the flipping mechanism, the whiteboard itself cannot rotate, which leads to discontinuity when writing formulas or derivation steps, making it inconvenient to record.

[0004] Therefore, how to provide an adjustable writing device for teaching that overcomes the shortcomings of existing whiteboard structures is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides an adjustable writing device for teaching, to solve the problem of inconvenient writing caused by the inability of the whiteboard to be actively rotated in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses an adjustable writing device for teaching, comprising: The bottom tray has several casters mounted on its bottom surface. A lifting assembly is inserted into the upper part of the bottom tray, and an adjustment component is installed on the top side of the lifting assembly; The mounting bracket is flipped and connected to one side surface of the adjustment assembly, and a whiteboard is mounted on the other side surface of the mounting bracket. The adjustment component is flipped and connected to the upper end of the lifting component.

[0007] In one possible implementation, the regulating component includes: A rotating disk has arc-shaped holes on its surface, and the arc-shaped holes are arranged in pairs; A tripod is fixed to the surface of the rotating disk, and sliding holes are provided on the surface of the tripod in pairs. The handle has one end passing through the arc-shaped hole and inserted into the mounting bracket, and the handle rod is drively connected to the arc-shaped hole; The rotating bolt passes sequentially through the end of the leg and the lifting assembly; A fixing bolt passes through the sliding hole and the lifting assembly in sequence, and the bolt rod is drivenly connected in the sliding hole.

[0008] In one possible implementation, the lifting component includes: The sleeve rod is inserted into the bottom tray at its bottom; The movable rod is connected in the sleeve rod via a transmission mechanism. The clamping bolt has one end inserted into the sleeve rod.

[0009] In one possible implementation, the bottom tray has storage holes on its upper surface, the storage holes are arranged in pairs, and the storage holes have a plurality of water inlet holes.

[0010] In one possible implementation, the mounting bracket includes: The connecting rods are arranged in pairs and have threaded holes on their surfaces. The threaded holes are arranged in pairs and the connecting rods are disposed on the surface of the rotating disk. The end of the handle is inserted into the threaded hole.

Detailed Implementation

[0016] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please refer to Figures 1-6 The present invention discloses an adjustable writing device for teaching, which consists of six parts, as follows: Figure 1It includes a mounting frame 1, a whiteboard 2, casters 3, a bottom tray 4, a lifting assembly 5, and an adjustment assembly 6. Several casters 3 are installed on the bottom surface of the bottom tray 4. The bottom of the lifting assembly 5 is inserted into the top of the bottom tray 4. The adjustment assembly 6 is installed on the top side of the lifting assembly 5. The mounting frame 1 is flipped and connected to one side surface of the adjustment assembly 6. The whiteboard 2 is installed on the other end surface of the mounting frame 1. The adjustment assembly 6 is flipped and connected to the top of the lifting assembly 5.

[0018] In use, the clamping bolt 51 is rotated so that one end of the clamping bolt 51 does not abut against the moving rod 53. Then, the moving rod 53 is allowed to slide in the sleeve 52 to change its position. The moving position is determined according to the user's usage. Then, the clamping bolt 51 is rotated again so that one end of the clamping bolt 51 abuts against the surface of the moving rod 53. The movement of the moving rod 53 is restricted by the clamping bolt 51, thereby restricting the position of the whiteboard 2. Then, rotate the rotating bolt 67 and the fixing bolt 64 to increase the distance between the rotating bolt 67 and the limiting nut 68, thereby releasing the clamping effect of the limiting nut 68 and the rotating bolt 67 on the moving rod 53 and the stand 65. At this time, the stand 65 can rotate along the screw of the rotating bolt 67, thereby realizing the flipping of the whiteboard 2. During the flipping process, the screw of the fixing bolt 64 will move along the sliding hole 63 to assist the flipping of the stand 65. After the flipping is completed, rotate the fixing bolt 64 to reduce the distance between the fixing bolt 64 and the limiting nut 68, causing the limiting nut 68 and the fixing bolt 64 to press the moving rod 53 and the stand 65. When the distance between the fixing bolt 64 and the limiting nut 68 is reduced to a certain extent, the moving rod 53 and the stand 65 will be pressed together, thereby fixing the position. At the same time, rotate the rotating bolt 67 to clamp the moving rod 53 and the stand 65, realizing secondary limiting. Finally, rotate handle 62 to increase the distance between handle 62 and connecting rod 11, thus removing the fixation of the mounting bracket 1. Then, move the screw of handle 62 along the arc-shaped hole 66 to achieve the rotation of the mounting bracket 1 on the plane. After determining the rotation angle, rotate handle 62 again to screw one end of handle 62 into the threaded hole 12, shortening the distance between handle 62 and connecting rod 11. This ensures that the connecting rod 11 is in close contact with the rotating disk 61 and that the screw of handle 62 does not move along the arc-shaped hole 66, thus achieving a fixed position. The rotation of the angle plane can be used to write different content.

[0019] In a specific embodiment, such as Figure 2The adjustment component 6 includes a rotating disk 61, a handle 62, a sliding hole 63, a fixing bolt 64, a foot 65, an arc-shaped hole 66, and a rotating bolt 67. The rotating disk 61 has an arc-shaped hole 66 on its surface, and the arc-shaped holes 66 are arranged in pairs. The foot 65 is fixed on the surface of the rotating disk 61, and the foot 65 has a sliding hole 63 on its surface, and the sliding holes 63 are arranged in pairs. One end of the handle 62 passes through the arc-shaped hole 66 and is inserted into the mounting bracket 1. The handle 62 rod is driven and connected in the arc-shaped hole 66. The rotating bolt 67 passes through the foot 65 and the end of the lifting component 5 in sequence. The fixing bolt 64 passes through the sliding hole 63 and the lifting component 5 in sequence. The fixing bolt 64 rod is driven and connected in the sliding hole 63. The leg 65 is fixed to the rotating disk 61 by welding. The sliding hole 63 is generally arc-shaped. With the rotating bolt 67 as the rotation center, the upper end of the leg 65 is provided with a round hole, which fits on the outside of the rotating bolt 67. At this time, the round hole rotates with the rotating bolt 67 as the rotation center, causing the bottom end of the leg 65 to move in a circle. During the rotation, the fixing bolt 64 does not move, and the sliding hole 63 moves in a circle along the fixing bolt 64. Alternatively, the arc shape does not change, and the diameter of the fixing bolt 64 is smaller than the width of the sliding hole 63. In this way, the circular movement of the leg 65 is not affected by the fixing bolt 64. However, after the leg 65 rotates, the fixing bolt 64 and the nut are used to clamp the leg 65 between the end of the fixing bolt 64 and the nut to achieve the limit of rotation.

[0020] In a specific embodiment, such as Figure 3 The lifting assembly 5 includes a clamping bolt 51, a sleeve rod 52, and a moving rod 53. The bottom of the sleeve rod 52 is inserted into the bottom tray 4, and the moving rod 53 is drivenly connected to the sleeve rod 52. One end of the clamping bolt 51 is inserted into the sleeve rod 52. The moving rod 53 achieves lifting and lowering by sliding in the sleeve rod 52, while the clamping bolt 51 is used to press against the moving rod 53, thereby restricting the movement of the moving rod 53.

[0021] In a specific embodiment, such as Figure 4 The bottom tray 4 has a pair of storage holes 42 on its upper surface, and several water inlet holes 41 in each storage hole 42. The storage holes 42 are designed to hold markers or books, making the whole device more convenient to use. The water inlet holes 41 are designed not only to prevent water from accumulating in the storage holes 42, but also to facilitate the retrieval of items. The casters 3 are provided for moving the whole device.

[0022] In a specific embodiment, such as Figure 5The mounting bracket 1 includes connecting rods 11, threaded holes 12, and connecting blocks 13. The connecting rods 11 are arranged in pairs, and threaded holes 12 are formed on their surfaces. The connecting rods 11 are mounted on the surface of the rotating disk 61, and the end of the handle 62 is inserted into the threaded hole 12. One end of the connecting block 13 is mounted on the end of the connecting rod 11. One end of the connecting block 13 connects the two connecting rods 11 together, and the other end of the connecting block 13 is connected to the whiteboard 2.

[0023] In a specific embodiment, such as Figure 6 The ends of the rotating bolt 67 and the fixing bolt 64 are inserted into the limiting nuts 68. One of the limiting nuts 68 is installed in the bracket 65, and the other limiting nut 68 is located outside the sliding hole 63. The limiting nuts 68 are provided for the rotation of the rotating bolt 67 and the fixing bolt 64.

[0024] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
