The utility model discloses a portable handwriting communication board, including the board frame, one side installation of board frame in winding assembly, winding assembly includes the reel, scroll spring, reel and installation cavity, and the reel outside is wound with writing tape, and the free end of writing tape is connected with extension assembly, and extension assembly includes the accommodation cavity, extension pull plate, cross lock bolt and pull handle. Advantageous effect lies in: the utility model discloses a winding assembly and extension assembly are installed on the board frame, so that the handwriting communication board can realize the increase of writing area according to the actual use needs of user when using, so that the language barrier user can express the thought completely in the communication, and the language barrier user and other people's smooth communication are convenient, make the handwriting communication board more flexible, and the use effect is better.

The invention relates to the field of teaching tools, in particular to an intelligent English language teaching board and a using method thereof.The intelligent English language teaching board comprises a fixing block and a supporting seat, a rotating mechanism is arranged in the fixing block, a sliding groove is formed in the outer wall of one side of the fixing block in a penetrating mode, and trapezoidal blocks are symmetrically connected to the inner wall of the sliding groove in a sliding mode; sliding holes are formed in the outer walls of the sides, away from the sliding grooves, of the fixing blocks in a penetrating mode, one ends of the two trapezoidal blocks extend out of the sliding holes and are fixedly connected with first white boards, supporting bases are arranged on the lower surfaces of the fixing blocks, the writing area of blackboard writing can be increased or decreased according to use requirements, and after the area of the white boards is adjusted, the white boards can be conveniently placed on the supporting bases. The height of the first whiteboard and the height of the second whiteboard can be adjusted according to the height of a user, the user does not need to manually rotate and replace cards, meanwhile, the storage rack can be moved upwards in batches, the storage rack does not need to rotate, whether the cards are rotated and replaced or not can be flexibly adjusted, and the memory ability of students is improved.

The utility model discloses a teaching display board for simulating investment, and particularly relates to the technical field of financial management teaching, which comprises a placing box and realizes a teaching simulation demonstration function through movement of an increase block and a decrease block so as to explain for students in a more detailed manner and vividly express data trend and rule change for the students through simulation. The second double-face writing board and the third double-face writing board are pulled out of the rectangular frame, explanation can be conducted for students according to mobile writing data of the rising block and the falling block, the teaching quality is improved in the form of image-text combination, and when writing layouts are not enough, a threaded rod can be rotated, so that the teaching quality and the teaching vitality are improved. The rack is driven to move, then the gear and the rotating shaft are driven to rotate, the rectangular frame is conveniently driven to rotate, then the first writing board is located on the front face, writing can be conducted on the other face of the second double-face writing board and the other face of the third double-face writing board, and the writing area is increased.

The utility model relates to the technical field of physics teaching, in particular to a teaching display board convenient to store, which comprises a bottom plate, supporting rods are fixed at the top of the bottom plate, connecting plates are fixed above the supporting rods in pairs, and slots are formed in the connecting plates in a penetrating manner; the display board is detachably connected to the supporting rod through a plurality of groups of inserting plates fixed on the back; and the fixing rings are mounted at the bottoms of the supporting rods. The display device overcomes the defects in the prior art, by arranging the connecting rods, the movable rings, the inserting plates and the inserting grooves, the display plates are lifted upwards firstly, the inserting plates on the backs of the display plates are separated from the inserting grooves, after the display plates are taken out, the rotary knobs are loosened to release the locking state of the movable rings, and then the supporting rods are squeezed inwards at the same time; the two sets of connecting rods upwards extrude the movable ring along with the rotating shaft between the two sets of connecting rods, the movable ring upwards moves on the supporting rod, after the movable ring reaches a proper position, the positioning rod is connected into the positioning hole to complete overall storage, and then the occupied space when the device is not used is reduced.
