Description

Technical Field

[0001] This utility model relates to the field of teaching demonstration boards, specifically a teaching demonstration board device with a flip-up multifunctional structure. Background Technology

[0002] Teaching demonstration equipment refers to various tools and equipment used to assist teachers in classroom teaching, display teaching content, and enhance teaching effectiveness. They help teachers deliver knowledge more vividly and efficiently through visual, auditory, or interactive methods, and improve students' learning interest and comprehension.

[0003] The most common teaching demonstration equipment is the blackboard. Usually, the blackboard is fixed between two support columns. When teaching, the teacher writes on the front of the blackboard with chalk. After writing, the teacher will show the text or graphics to the students and let them think. After a period of time, the teacher will teach. After teaching, the blackboard will be erased and new knowledge will be written. However, this is relatively time-consuming, and the amount of knowledge taught in the limited time is relatively small. Utility Model Content

[0004] The technical problem this utility model aims to solve is: when teachers are teaching, they write on the front of the blackboard with chalk. After writing, they show the text or graphics to the students and let them think. After a period of time, they teach. After teaching, they erase the chalk and write new knowledge. However, this is time-consuming and the amount of knowledge taught in a limited time is relatively small.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: including a base, vertical rods fixedly disposed on the left and right sides of the top of the base, a mounting frame disposed between the two vertical rods, and a demonstration board rotatably disposed inside the mounting frame. The top of the mounting frame is provided with a limiting component for restricting the movement of the demonstration board.

[0006] The limiting component includes a guide seat fixedly mounted on the top of the mounting frame. A guide rod is slidably mounted inside the guide seat. A crossbar is fixedly mounted at the bottom of the guide rod. Both ends of the crossbar pass through the left and right sides of the guide seat and are slidably connected to the guide seat. Connecting rods are fixedly mounted at the bottom ends of the left and right sides of the crossbar. A limiting plate is fixedly mounted at the bottom end of the connecting rod. The upper and lower ends of the limiting plate pass through the inner and outer sides of the mounting frame. A limiting groove matching the limiting plate is opened at the top of the demonstration board. The top of the crossbar is connected to the top of the inner wall of the guide seat by a return spring, and the return spring is sleeved on the outside of the guide rod. The top end of the guide rod extends to the outside of the guide seat.

[0007] The beneficial effects of this utility model are as follows: by setting both sides of the blackboard to be writable and the blackboard to be rotatable, and then limiting it with a limiting component, knowledge can be written on both sides of the blackboard. After one side is displayed, it can be flipped to display the other side. When displaying the other side, the content of the original side can be replaced, thereby achieving the effect of saving time.

[0008] Furthermore, a connecting plate is fixedly provided on the rear side of the guide rod, and two mounting blocks are fixedly provided on the rear bottom end of the connecting plate, with a movable rod rotatably provided between the two mounting blocks.

[0009] The beneficial effects of this utility model are as follows: by setting up a movable rod, it is convenient to move the guide rod, avoiding the problem that the guide rod is too high and inconvenient to move, thereby improving the applicability of the device.

[0010] Furthermore, mounting bases are fixedly provided at the bottom of the front and rear sides of the mounting frame, a collection groove is provided at the top of the mounting base, a guide block is slidably arranged in the collection groove, and a scraper is fixedly provided at the bottom of the guide block.

[0011] Furthermore, a drainage tube is fixedly installed at the bottom of the mounting frame, the top end of the drainage tube extends into the collection groove, and a sealing cap is threaded to the bottom of the drainage tube. Anti-slip stripes are evenly distributed on the surface of the sealing cap.

[0012] Furthermore, a push rod is fixedly installed on the top of the guide block, and a rubber sleeve is fixedly installed on the surface of the push rod.

[0013] Furthermore, the bottom end of the limiting plate is specifically arc-shaped.

[0014] This utility model provides a flip-up, multi-functional teaching demonstration board device. It offers the following advantages:

[0015] (1) By setting both sides of the blackboard to be able to be written on and the blackboard to be able to rotate, and then using a limiting component to limit it, knowledge can be written on both sides of the blackboard. After one side is displayed, it can be flipped to display the other side. When displaying the other side, the content of the original side can be replaced, thereby saving time.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0025] Example:

[0026] like Figure 1-6 As shown, a teaching demonstration board device with a flip-up multi-functional structure includes a base 1, vertical rods 2 fixedly disposed on the left and right sides of the top of the base 1, a mounting frame 3 disposed between the two vertical rods 2, and a demonstration board 4 rotatably disposed inside the mounting frame 3. The top of the mounting frame 3 is provided with a limiting component 5 for restricting the movement of the demonstration board 4.

[0027] The limiting component 5 includes a guide seat 51 fixedly mounted on the top of the mounting frame 3. A guide rod 53 is slidably mounted inside the guide seat 51. A crossbar 54 is fixedly mounted at the bottom of the guide rod 53. The two ends of the crossbar 54 pass through the left and right sides of the guide seat 51 and are slidably connected to the guide seat 51. A connecting rod 55 is fixedly mounted at the bottom of the left and right sides of the crossbar 54. A limiting plate 52 is fixedly mounted at the bottom of the connecting rod 55. The upper and lower ends of the limiting plate 52 pass through the inner and outer sides of the mounting frame 3. A limiting groove matching the limiting plate 52 is opened on the top of the demonstration plate 4. The top of the crossbar 54 is connected to the top of the inner wall of the guide seat 51 by a return spring, and the return spring is sleeved on the outside of the guide rod 53. The top of the guide rod 53 extends to the outside of the guide seat 51.

[0028] Once one side of the content has been displayed, the guide rod 53 is moved upwards, which in turn moves the horizontal bar 54, which in turn moves the connecting rod 55, which in turn moves the limiting plate 52 upwards, causing the limiting plate 52 to disengage from the limiting groove and release the limitation on the demonstration board 4. At this point, the demonstration board 4 is rotated 180 degrees to bring the reverse side to the front. The guide rod 53 is then released, and the horizontal bar 54 is moved downwards by the return spring, which in turn moves the connecting rod 55 downwards, causing the limiting plate 52 to move downwards and into the limiting groove, thus limiting the demonstration board 4. When displaying the reverse side, the content on the front side can be erased and new content can be written, thereby saving time.

[0029] A connecting plate 56 is fixedly installed on the rear side of the guide rod 53. Two mounting blocks 57 are fixedly installed on the rear side of the bottom end of the connecting plate 56. A movable rod 58 is rotatably installed between the two mounting blocks 57.

[0030] By setting up the movable rod 58, pushing the movable rod 58 upward can drive the connecting plate 56 to move, which in turn drives the guide rod 53 to move. Since the movable rod 58 is set to rotate, it will not affect the rotation of the demonstration board 4.

[0031] Mounting bases 31 are fixedly installed on the front and rear bottom ends of mounting frame 3. A collection groove is opened on the top of mounting base 31, and a guide block 35 is slidably installed in the collection groove. A scraper 36 is fixedly installed at the bottom of guide block 35.

[0032] Because of the mounting base 31 and the collection slot on the top of the mounting base 31, chalk dust that falls when writing can be collected and prevented from falling to the ground. By moving the scraper 36, the chalk dust can be scraped to one side.

[0033] A drainage tube 32 is fixedly installed at the bottom of the mounting frame 3. The top end of the drainage tube 32 extends into the collection tank. A sealing cap 33 is threadedly connected to the bottom of the drainage tube 32. Anti-slip stripes are evenly distributed on the surface of the sealing cap 33.

[0034] By setting up the drainage pipe 32, chalk dust can be discharged into the collection tank through the drainage pipe 32, thus achieving the cleaning effect.

[0035] A push rod 34 is fixedly installed on the top of the guide block 35, and a rubber sleeve 37 is fixedly installed on the surface of the push rod 34.

[0036] The bottom end of the limiting plate 52 is specifically arc-shaped.

[0037] Working principle: After one side of the knowledge has been displayed, the guide rod 53 is moved upward, which in turn moves the horizontal bar 54, which in turn moves the connecting rod 55, which in turn moves the limiting plate 52 upward, causing the limiting plate 52 to disengage from the limiting groove and release the limitation on the demonstration board 4. At this time, the demonstration board 4 is rotated 180 degrees to bring the reverse side to the front. The guide rod 53 is released, and the return spring moves the horizontal bar 54 downward, which in turn moves the connecting rod 55 downward, which in turn moves the limiting plate 52 downward, causing the limiting plate 52 to abut into the limiting groove, thus limiting the demonstration board 4. When displaying the reverse side, the content on the front side can be erased and new content can be written, thereby saving time.
