[0014] (III) Beneficial effects Compared with the prior art, the present invention provides a teaching material and teaching aid management device, which has the following beneficial effects: 1. The rotating groove and telescopic guide groove arranged inside the built-in partition are convenient for the deflection of the connecting rod and the guiding sliding of the vertical pressure rod. The multi-link structure composed of the connecting rod, L-shaped support, rotating connecting seat, rotating connecting rod and vertical pressure rod can drive the vertical pressure rod to press down by the weight of the teaching aids themselves when the teaching aids are placed on the support table, so as to synchronously drive the connecting rod to deflect in combination with the multi-link structure, so that the arc-shaped closing pieces at the top of the connecting rod are close to each other to achieve automatic closing, and through the mutual closing between the two arc-shaped closing pieces, a limited space is quickly constructed on the top of the support table, and the rubber thin rod on the inner side of the arc-shaped closing piece can be used to flexibly limit and support the teaching aids in the limited space, so that the teaching aids can be placed more stably in the limited space, and the evenly arranged rubber thin rods can support teaching aids with different special-shaped structures, providing adaptability to the limited space.

[0015] 2. By arranging a counterweight block on the back of the two arc-shaped closing pieces, the deflection force between the arc-shaped closing pieces can be increased when the arc-shaped closing pieces are deflected under the drive of the connecting rod, so that the two groups of arc-shaped closing pieces can move toward each other quickly. At the same time, the adsorption magnetic strips arranged on the opposite sides of the two arc-shaped closing pieces can increase the attraction for the arc-shaped closing pieces to move toward each other when they are closed, so that the two arc-shaped closing pieces can maintain a relatively stable state after closing, thereby maintaining the limited space from deformation and facilitating better support and placement of teaching aids.

[0016] 3. By arranging an installation sleeve, a support spring, a limit plate and a guide rod between the built-in partition and the support platform, when the support platform descends, the guide rod and the limit plate can be lowered in the installation sleeve, thereby compressing the support spring and accumulating force in the support spring. After the teaching aids on the support platform are taken away, there is no additional gravity on the support platform, so that the support spring can be quickly reset, so that the support platform moves up and synchronously drives the arc-shaped closing piece to move away, so as to facilitate the taking of teaching aids and the subsequent re-placement of the teaching aids.

[0017] 4. By installing the cabinet on the side, the circulation slot, the air inlet slot, the exhaust slot and the fan, the air inlet and outlet ducts can be constructed on both sides of the management cabinet, so as to improve the ventilation capacity inside the management cabinet in the actual application process. At the same time, with the drying box, the airflow entering from the outside and the airflow inside the management cabinet can be dried and dehumidified during the ventilation process, so as to ensure the dryness inside the management cabinet and prevent the teaching aids from being damaged when stored due to the humid environment inside the management cabinet; Based on the engaging groove, connecting tension spring and sealing plate at the exhaust groove, the sealing plate can be pushed to move based on the pressure of the exhaust airflow during exhaust, so that the sealing plate drives the connecting tension spring to stretch, so that the airflow can be quickly discharged through the gap between the sealing plate and the edge of the side-mounted cabinet without affecting the exhaust. At the same time, after the exhaust is completed, the automatic reset of the connecting tension spring can be used to facilitate the reset of the sealing plate, thereby sealing the exhaust groove, so as to avoid the entry of external dust and dirt when the exhaust groove is not exhausted, thereby contaminating the teaching aids.

[0018] 5. Through the exhaust top plate, mounting frame, movable frame, air trough, liquid storage sponge, thin spring, squeezing switch and top cover, when the humidity inside the management cabinet is heavy during the rainy season, the liquid storage sponge can absorb and accumulate the moisture and the water stains in the moisture, and when the water stains accumulated inside the liquid storage sponge reach a certain amount, the weight of the liquid storage sponge increases, so that the liquid storage sponge will drive the movable frame to move down on the inner side of the mounting frame, and the movable frame moves down to squeeze the thin spring and press the squeezing switch, and the fan can be quickly and conveniently turned on by squeezing the switch. When the humidity inside the management cabinet is high, the fan can be turned on through the active response of the liquid storage sponge, thereby realizing active and rapid ventilation and dehumidification, and avoiding the high humidity inside the management cabinet causing mold and damage to the teaching aids.

[0031] The working principle and use process of the present invention are as follows: when the teaching aids are stored, the teaching aids need to be placed on the support platform 12 on the top of the built-in partition 4, and the rotation groove 5 and the telescopic guide groove 6 inside the built-in partition 4 facilitate the deflection of the connecting rod 7 and the guided sliding of the vertical pressure rod 11. Based on the multi-link structure composed of the connecting rod 7, the L-shaped support 8, the rotating connecting seat 9, the rotating connecting rod 10 and the vertical pressure rod 11, when the teaching aids are placed on the support platform 12, the vertical pressure rod 11 can be pressed down by the weight of the teaching aids themselves, thereby synchronously driving the connecting rod 7 to deflect in combination with the multi-link structure, so that the arc-shaped closing pieces 14 at the top of the connecting rod 7 are close to each other to achieve automatic closure; In the process of the two arc-shaped closing pieces 14 closing toward each other, a limited space is quickly constructed on the top of the support platform 12, and the thin rubber rods 17 on the inner side of the arc-shaped closing piece 14 can be used to flexibly limit and support the teaching aids in the limited space, so that the teaching aids can be placed more stably in the limited space, and the uniformly arranged thin rubber rods 17 can support teaching aids with different special-shaped structures, providing adaptability of the limited space; When the two arc-shaped closed pieces 14 are closed toward each other, a counterweight 15 is arranged on the back of the two arc-shaped closed pieces 14, so that when the arc-shaped closed pieces 14 are deflected under the drive of the connecting rod 7, the deflection force therebetween can be increased, so that the two groups of arc-shaped closed pieces 14 can move toward each other quickly, and at the same time, the adsorption magnetic strips 16 arranged on the opposite sides of the two arc-shaped closed pieces 14 can increase the attraction for the arc-shaped closed pieces 14 to move toward each other when they are closed toward each other, so that the two arc-shaped closed pieces 14 can maintain a relatively stable state after closing, thereby maintaining the limited space from deformation, and facilitating better support and placement of teaching aids; In addition, when the teaching aid drives the support platform 12 and the vertical pressure rod 11 to press down, the guide rod 21 and the limit plate 20 are lowered in the installation sleeve 18 by pressure, thereby compressing the support spring 19, so that the support spring 19 accumulates force, and after the teaching aid on the support platform 12 is taken, there is no additional gravity on the support platform 12, so that the support spring 19 is quickly reset, so that the support platform 12 moves up, and synchronously drives the arc-shaped closing piece 14 to move away, so as to facilitate the taking of the teaching aid and the subsequent re-placement of the teaching aid; When the teaching aids are stored in the management cabinet 1, the side-mounted cabinet 30, the circulation slot 31, the air inlet slot 32, the exhaust slot 33 and the fan 34 can be used to construct air inlet and outlet ducts on both sides of the management cabinet 1.

At the same time, in conjunction with the drying box 35, the airflow entering from the outside and the airflow inside the management cabinet 1 can be dried and dehumidified during the ventilation process to ensure the dryness inside the management cabinet 1 and prevent the teaching aids from being damaged due to the humid environment inside the management cabinet 1 when they are stored. When the exhaust slot 33 is exhausted, the sealing plate 38 is pushed to move based on the pressure of the exhaust airflow, so that the sealing plate 38 drives the connecting tension spring 37 to stretch, so that the airflow can be quickly discharged through the gap between the sealing plate 38 and the edge of the side installation cabinet 30 without affecting the exhaust. At the same time, after the exhaust is completed, the automatic reset of the connecting tension spring 37 is used to facilitate the reset of the sealing plate 38, so as to achieve the blocking of the exhaust slot 33, so as to avoid the entry of dust and dirt from the outside when the exhaust slot 33 is not exhausted, causing pollution to the teaching aids; In addition, when the humidity inside the management cabinet 1 is heavy during the rainy season, the moisture and the water stains in the moisture are adsorbed and accumulated through the liquid storage sponge 26, and when the water stains accumulated inside the liquid storage sponge 26 reach a certain amount, the weight of the liquid storage sponge 26 increases, so that the liquid storage sponge 26 will drive the movable frame 24 to move down on the inner side of the mounting frame 23, and the movable frame 24 moves down to squeeze the thin spring 27 and press the squeezing switch 28, and the fan 34 is quickly and conveniently turned on by squeezing the switch 28. In this way, when the humidity inside the management cabinet 1 is high, the fan 34 can be turned on through the active response of the liquid storage sponge 26, thereby realizing active and rapid ventilation and dehumidification, and avoiding the high humidity inside the management cabinet 1 causing mold and damage to the teaching aids.
