Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, specifically to a push-pull smart blackboard with a frameless push-pull sub-board. Background Technology

[0002] The existing push-pull smart blackboard has a touch screen installed in the middle of the main frame, and push-pull sub-boards installed on both sides of the touch screen. The main body of the sub-board is glass, the front of the glass is covered with a metal plate, and the four sides of the glass are reinforced with long strip metal frames. This design has two drawbacks: first, the height difference between the sub-board and the touch screen is large, which makes it uncomfortable for teachers to use; second, when the two sub-boards are joined, the joint is separated by the metal frame, making continuous writing impossible. Utility Model Content

[0003] To address the technical problems of large height difference between the sub-board and the touch screen in existing push-pull smart blackboards, and the fact that the two sub-boards are separated by a metal frame when joined together, this application proposes a push-pull smart blackboard with a frameless push-pull sub-board, thus solving the aforementioned technical problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides a sliding smart blackboard with frameless sliding sub-boards, including a frame and two sliding sub-boards for writing. The two sliding sub-boards are slidably fitted on both sides of the frame. After the two sliding sub-boards are moved, they are joined together in the center of the frame. The board includes a filling material and a rigid writing layer that is integrally covered on the filling material. One side of the rigid writing layer is formed as a writing surface. The board is connected to the frame only through a sheet metal part disposed on the top, so that the two writing surfaces are connected after being joined.

[0006] Furthermore, after being bent once, the sheet metal of the push-pull sub-plate forms two mutually perpendicular connecting pieces. One of the connecting pieces is vertically arranged and connected to the mounting surface of the plate near the frame, while the other connecting piece is horizontally arranged and slidably fitted to the top of the frame.

[0007] Furthermore, the push-pull subplate is fitted onto the frame via a sliding assembly, which includes a sliding rail and a slider that cooperate with each other. The sliding rail is mounted on the top of the frame, and the slider is connected to the bottom surface of the horizontally arranged connecting piece.

[0008] Furthermore, the sheet metal part has a supporting triangle formed at the corner of the two connecting pieces, and the supporting triangle is formed by the material at the corner being recessed from the outside to the inside.

[0009] Furthermore, the vertically arranged connecting piece of the sheet metal part has multiple fixing holes, and the sheet metal part is riveted or screwed to the body of the push-pull sub-plate through the fixing holes.

[0010] Furthermore, the horizontally arranged connecting piece of the sheet metal part is provided with circular holes and elongated holes for assembly.

[0011] Furthermore, it also includes a touch screen, which is disposed in the center of the front of the frame, and the two push-pull sub-plates are joined together to cover the display surface of the touch screen.

[0012] Furthermore, a grip handle is provided at the bottom of the writing surface of the board.

[0013] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0014] This utility model discloses a sliding smart blackboard with a frameless sliding sub-panel. The interior of the sliding sub-panel is filled with a material, while the exterior is covered with a rigid writing layer. This internal filling material allows for a thinner board while maintaining rigidity, thus reducing the height difference between the sliding sub-panel and the touch screen. Simultaneously, the rigid writing layer provides a smooth edge and a stable and robust structure, eliminating the need for a secondary reinforcement frame at the edges. One side of the rigid writing layer can be used directly as a writing surface. This means that when the two sliding sub-panels are joined, there is no frame separating the two writing surfaces, allowing for continuous writing. Teachers can write continuously at the joint. Furthermore, eliminating the need for a reinforcing frame reduces overall cost. Attached Figure Description

[0023] like Figure 1-6 As shown, this utility model provides a sliding smart blackboard with frameless sliding sub-boards, including a frame 1 and two sliding sub-boards 2 for writing. The two sliding sub-boards 2 are slidably fitted on both sides of the frame 1. After the board bodies 21 of the two sliding sub-boards 2 are moved, they are spliced ​​together in the center of the frame 1. The board body 21 includes a filling material and a rigid writing layer that is entirely covered on the filling material. The filling material can be a non-metallic foam material. The side of the rigid writing layer facing away from the frame 1 forms a writing surface 211.
