[0019] See also Figure 1 and 2 , showing a schematic diagram of an embodiment of adjusting the orientation of the device according to needs in the utility model;

[0020] A display and lecture board, comprising a support frame 101, a plug board 201 and a core board 202, wherein an inverted T-shaped groove is provided on the top surface of the support frame 101, the plug board 201 and the core board 202 are plugged into each other, the outer ends of the plug board 201 and the core board 202 are fixed with T-shaped blocks, the plug board 201 and the core board 202 are slidably connected to the two sides of the inverted T-shaped groove through the T-shaped blocks, the plug board 201 and the core board 202 are hinged with display boards 203, and the two display boards 203 are hingedly connected;

[0021] The support frame 101 is fixed on the ground, the plug board 201, the core board 202 and the two display boards 203 are all writing boards, the core board 202 can slide in the plug board 201, so as to change the overall writing area of ​​the plug board 201 and the core board 202, and the plug board 201 and the core board 202 slide away from each other and unfold, which drives the two display boards 203 to rotate, and the two display boards 203 are close to the plug board 201 and the core board 202 and are close to the coplanar state, and face the same direction. At this time, the two display boards 203 and the plug board 201 and the core board 202 can be displayed in the front and back directions. When the plug board 201 and the core board 202 move close to each other and the core board 202 is stored in the plug board 201, the two display boards 203 are driven to unfold to form a certain angle, such as Figure 1 and 2 As shown, at this time, the two display boards 203 are facing two different directions respectively, so that the device can be displayed to the public in three different directions; therefore, the relative position between the plug board 201 and the core board 202 can be adjusted according to needs. When the core board 202 is pulled out from the plug board 201, the writing surface of the device becomes larger and can be displayed in two directions. When the core board 202 is stored in the plug board 201, the two display boards 203 are unfolded at a certain angle, and the device can be displayed in three directions.

[0022] See also Figure 6 , showing a schematic diagram of an embodiment of preventing the center of gravity of the device from shifting due to the unfolding of two display panels 203 according to the utility model;

[0023] The lower end of the support frame 101 is symmetrically fixed with two rotating shafts 104, and the two rotating shafts 104 are rotatably connected with a rotating frame 105;

[0024] When the two display panels 203 are in the unfolded state, in order to prevent the device from being overweight, the two rotating frames 105 can be rotated so that the two rotating frames 105 are respectively rotated to the lower ends of the two display panels 203, thereby providing auxiliary support for the device and preventing the center of gravity of the device from shifting due to the unfolded two display panels 203, thereby increasing the stability of the device.

[0025] See also Figure 6 , showing a schematic diagram of an embodiment of fixing the angles of two rotating racks 105 according to the utility model;

[0026] The upper ends of the two rotating frames 105 are both threadedly connected with studs 106, and the bottom surfaces of the two display boards 203 are both provided with insertion holes II 204 capable of inserting the studs 106;

[0027] When the two rotating frames 105 are rotated to the lower ends of the two unfolded display panels 203 respectively, the two studs 106 are screwed so that the upper ends of the two studs 106 are respectively inserted into the two sockets II 204, thereby fixing the angles of the two rotating frames 105 and further providing auxiliary support to the two display panels 203 from the lower ends where the two display panels 203 are connected.

[0028] See also Figure 7 , showing a schematic diagram of an embodiment of making the rotating rack 105 rotate more smoothly according to the utility model;

[0029] The lower ends of the two rotating frames 105 are rotatably connected with universal wheels 107;

[0030] The two universal wheels 107 are supported by rolling on the ground, thereby reducing the friction between the rotating frame 105 and the ground, making the rotating frame 105 rotate more smoothly.

[0031] See also Figure 3 and 6 , showing a schematic diagram of an embodiment of fixing two rotating racks 105 in a storage state according to the utility model;

[0032] The support frame 101 is provided with two insertion holes Ⅰ 103 into which the studs 106 can be inserted;

[0033] When the two rotating frames 105 are stored in the support frame 101, the two studs 106 are screwed so that the upper ends of the two studs 106 are respectively inserted into the corresponding insertion holes Ⅰ 103, thereby fixing the angles of the two rotating frames 105 in the stored state.

[0034] See also Figure 1 , 2 and 6, which are schematic diagrams showing an embodiment of the present invention for avoiding interference between two rotating racks 105 when they are stored;

[0035] The two insertion holes Ⅰ 103 are centrally symmetrically arranged relative to the core of the support frame 101;

[0036] The two rotating racks 105 in the storage state are both in an inclined state, so that the two rotating racks 105 can be staggered with each other. Figure 1 and 2 As shown, interference between the two rotating racks 105 when they are stored can be avoided. When the two rotating racks 105 are unfolded, the two rotating racks 105 can be unfolded sequentially.

[0037] See also Figure 6 , showing a schematic diagram of an embodiment of changing the relative position between the plug board 201 and the core board 202 according to the utility model;

[0038] The upper end of the support frame 101 is rotatably connected with a bidirectional screw rod 102, and the T-blocks on the insert plate 201 and the core plate 202 are respectively threadedly connected to the two ends of the bidirectional screw rod 102;

[0039] Rotating the bidirectional screw 102 drives the two T-blocks to move closer to or away from each other, thereby driving the plug plate 201 and the core plate 202 to move closer to or away from each other, thereby changing the relative position between the plug plate 201 and the core plate 202. Since the bidirectional screw 102 and the T-block have the characteristic of self-locking threads, the relative position between the plug plate 201 and the core plate 202 can be fixed after adjustment.

[0040] See also Figure 4 , showing a schematic diagram of an embodiment of avoiding jamming between two display boards 203 according to the utility model;

[0041] A convex edge 205 is fixedly connected to one side of the plug board 201 close to the display board 203;

[0042] When the display panel 203 is rotated close to the plug board 201, it can fit on the convex edge 205, so that a certain angle is formed between the display panel 203 fitted on the convex edge 205 and the plug board 201, and then when the core board 202 is inserted into the plug board 201, the two display panels 203 have a tendency to move outward and expand, thereby avoiding jamming between the two display panels 203.

[0043] See also Figure 7 , showing a schematic diagram of an embodiment of reducing the wind resistance surface according to the utility model;

[0044] The two rotating frames 105 are both hollow in shape. When the device is used in an outdoor environment, the hollow rotating frames 105 can reduce the wind resistance surface, making the device more stable during use.

[0045] See also Figure 3 , showing a schematic diagram of an embodiment of fixing the device on a designated ground by screws according to the utility model;

[0046] The legs at the lower end of the support frame 101 are provided with screw insertion holes for inserting screws to fix the device on a designated ground.
