Description

Technical Field

[0001] The utility model relates to the technical field of teaching, in particular to a teaching auxiliary board. Background Art

[0002] Teaching is a unique talent cultivation activity composed of teachers' teaching and students' learning. During teaching, in addition to the large blackboard in the classroom, in order to facilitate better teaching for students, important knowledge will be written on the small blackboard, and then cases of important knowledge will be written on the large blackboard to prevent important knowledge from being erased, resulting in some students not being able to write it down and memorize it in time.

[0003] However, in the prior art, small blackboards are usually small, which sometimes leads to insufficient area for writing important knowledge. Small blackboards are too large and inconvenient to store in the classroom. At the same time, small blackboards do not have fixed mechanisms. If too much force is used when writing important knowledge, the small blackboard may tilt and need to be erased and rewritten, which is very inconvenient. Therefore, a teaching auxiliary board is needed. Utility Model Content

If too much force is used when writing important knowledge, the small blackboard may tilt, and the writing needs to be erased and rewritten. The problems raised in the background technology are solved by providing a foldable small blackboard and a fixing mechanism.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a teaching auxiliary board, comprising: an adjustable rod, a support plate fixedly installed on the top of the adjustable rod, a fixed plate welded to the bottom of the support plate, a main blackboard fixedly installed on the top of the support plate, connecting hinges fixedly installed on both sides of the outer wall of the main blackboard, two connecting hinges fixedly installed on one side of the outer walls of the two connecting hinges, fixed blocks fixedly installed on the back surfaces of the two auxiliary blackboards, threaded rods movably installed on the inner walls of the two fixed blocks in the form of earrings, threaded cylinders rotatably sleeved on the outer walls of the two threaded rods, and suction cups fixedly installed on one end of the outer walls of the two threaded cylinders.

[0006] Preferably, two first insertion frames are fixedly installed on the back surface of the two auxiliary blackboards, and four second insertion frames are fixedly installed on the back surface of the main blackboard. The inner walls of the four second insertion frames are movably provided with insertion blocks, so that the two auxiliary blackboards can be fixed by the insertion blocks after being unfolded.

[0007] Preferably, the back surfaces of the two auxiliary blackboards are fixedly installed with fixed shafts, the outer wall of one of the two fixed shafts is movably provided with a rotating block, and the inner wall of the rotating block is engaged with the outer wall of the other one of the two fixed shafts, so that the two auxiliary blackboards can be fixed by the rotating block when they are closed.

[0008] Preferably, a base plate is fixedly mounted at the bottom of the adjustable rod, and a universal wheel is arranged at the bottom of the base plate, so that when the device needs to be moved, the device can be driven to move by the universal wheel.

[0009] Preferably, two handles are welded to the top of the bottom plate, and the outer walls of the two handles are fixedly covered with rubber sleeves, so that when the device needs to be lifted to the teacher's desk, the device can be lifted by holding the handles.

[0010] Preferably, storage grooves are provided on the front surface of the main blackboard and the front surfaces of the two auxiliary blackboards, so as to facilitate the storage of teaching tools in the storage grooves and prevent tools such as writing pens from falling on the ground.

[0011] Preferably, baffles are movably installed on the front surface of the main blackboard and the front surfaces of the two auxiliary blackboards through hinges, so that the baffles can be used to cover the storage slots to prevent tools from falling out.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by setting a secondary blackboard and a suction cup, after the device is moved to the podium, the two secondary blackboards are unfolded by connecting the hinges, and after the threaded rod is in a horizontal position, the suction cup is sucked onto the wall to fix the blackboard, so that the secondary blackboard and the main blackboard are used to increase the area of ​​the overall blackboard, providing a larger area for teachers to write important knowledge, and also to write knowledge points with force, so that students can see more clearly, thereby improving the quality of teaching. When the device is not needed, it is only necessary to fold the secondary blackboard using the hinge, so that the overall width of the device will be reduced, which is convenient for storage.

[0014] 2. In the utility model, universal wheels and handles are provided to improve the mobility of the device. Since the teacher's desk in the classroom has steps, when the device needs to be moved to the teacher's desk, the handle can be held to lift the device to the teacher's desk. Then a storage slot and a baffle are provided. After writing is completed, teaching tools such as pens and blackboard erasers can be placed in the storage slot and blocked with a baffle for easy storage, thereby improving the comfort of the device.
