Description

Technical Field

[0001] The utility model relates to the technical field of office equipment, in particular to a blackboard for conferences. Background Art

[0002] A meeting is a process of collective discussion, communication and decision-making. Its main purpose is to allow participants to jointly discuss a problem, formulate strategies or reach a consensus. Meetings usually involve information sharing, exchange of views and problem solving. In order to improve the effectiveness and efficiency of meetings, using a blackboard as an auxiliary tool has significant advantages. The blackboard helps to visualize information. The content often discussed in meetings includes complex concepts, data and processes. If these contents are only described in words, it is easy to make people feel vague and confused. By drawing diagrams, flow charts or key points on the blackboard, these complex information can be presented in a graphical way, which can more intuitively understand and grasp the core content of the discussion. In addition, the blackboard can also facilitate the review and summary of the main points of the discussion. If there are records on the blackboard during the meeting, everyone can quickly recall the content and decisions discussed based on these visual records, making it easier to organize and summarize the results of the meeting.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the embodiments of the present application easy to understand, the embodiments of the present application are further explained below in combination with diagrams and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0022] Figure 1 The utility model schematically shows a blackboard for conference, including a base plate 1, which is cross-shaped, and the four corners of the bottom of the base plate 1 are provided with support legs 15 integrally formed with the base plate 1, and a fixed column 12 is fixedly installed on the top of the base plate 1, and the fixed column 12 is a hollow structure, and a movable column 13 is slidably installed in the fixed column 12, and a fixing device 2 is provided in the fixed column 12 and the movable column 13, and the movable column 13 can be fixedly connected to the fixed column 12 through the fixing device 2, and a connecting device 3 is provided on the top of the movable column 13, and a teaching board 14 is movably connected to the top of the movable column 13 through the connecting device 3. The sharp parts of the base plate 1 are provided with rounded corners 4, and the rounded corners 4 can effectively reduce the damage caused by bumps and can also avoid scratching the user. Universal wheels 5 are fixedly installed on the bottom ends of the support legs 15, and the universal wheels 5 can adopt models with self-locking functions such as A504, which are convenient for moving this equipment. An iron sheet is provided in the teaching board 14, and a pair of magnets 6 are placed on the top of the teaching board 14, which makes it convenient for users to clamp some paper documents or photos through the magnets 6 to improve the meeting effect.

[0023] like Figure 2 and Figure 3The fixing device 2 shown includes a through hole 21 and a receiving groove 22. There are multiple through holes 21, and the multiple through holes 21 are vertically opened on the surface of the fixed column 12. The receiving groove 22 is opened in the inner wall of the bottom end of the movable column 13. A first spring 23 is provided in the receiving groove 22. One end of the first spring 23 is fixedly connected to the bottom end of the receiving groove 22, and the other end is fixedly connected to a telescopic column 24. The telescopic column 24 is arranged through the through hole 21. The end of the telescopic column 24 away from the receiving groove 22 is fixedly installed with a dome 7. The semicircular structure of the dome 7 can effectively reduce the contact area, thereby reducing friction and facilitating sliding.

[0024] In a specific implementation, it is only necessary to press the dome 7 hard, so that the dome 7 pushes the telescopic column 24 to move and compress the first spring 23. When the dome 7 passes through the through hole 21, the movable column 13 can be slid, thereby facilitating the adjustment of the height of the teaching board 14. When the movable column 13 is adjusted to a suitable height, the compressed first spring 23 will apply a little of the telescopic column 24 to pass through the through hole 21, thereby completing the fixation.

[0025] like Figure 2 and Figure 4 The connecting device 3 shown includes a mounting groove 31 and a through-hole 32. The mounting groove 31 is opened at the top of the movable column 13. A through-hole 32 is opened at the top of the movable column 13. Fixed grooves 33 are opened on both sides of the through-hole 32. A fixed block 34 is movably installed in the fixed groove 33. A connecting column 35 is fixedly connected to the top of the fixed block 34. The top of the connecting column 35 is fixedly connected to the teaching board 14. The bottom end of the fixed block 34 contacts a reinforcement block 36. The bottom end of the reinforcement block 36 is fixedly connected to a second spring 37. The other end of the second spring 37 is fixedly connected to the bottom end of the mounting groove 31.

[0026] In the specific implementation, it is only necessary to install the teaching board 14 downward so that the teaching board 14 presses down the fixing block 34 through the connecting column 35, thereby causing the fixing block 34 to leave the fixing groove 33 and press down the reinforcement block 36. The downward movement of the reinforcement block 36 will compress the second spring 37. At this time, the teaching board 14 can be rotated to turn it over and realign the fixing block 34 with the fixing groove 33 and then let go. The compressed second spring 37 will reset and push the reinforcement block 36 to confine the fixing block 34 in the fixing groove 33, thereby completing the turning over. If you want to disassemble the device, you only need to rotate the fixing block 34 when the fixing block 34 leaves the fixing groove 33 so that it is aligned with the through hole 32 to remove the fixing block 34, thereby separating the teaching board 14 from the movable column 13 and completing the disassembly.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
