DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. Example

[0023] according to Figure 1 , 2 As shown in Figures 3, 4, 5 and 6, a mobile teaching device for school teaching is proposed in this embodiment, including a cabinet 1, a pulley 2 is provided at the lower end of the cabinet 1, a storage slot 3 is provided at the upper end of the cabinet 1, a display board 4 is provided in the storage slot 3, the display board 4 is slidably connected to the storage slot 3, and the upper end surface of the display board 4 is flush with the upper end surface of the cabinet 1; when the display board 4 is in use, the gear transmission member will control the plug plate 7 to move upward, and the plug plate 7 will lift the display board 4 upward along the storage slot 3 during movement, so that the display board 4 is placed on the upper end of the cabinet 1. When the display board 4 is idle, the gear transmission member will pull the display board 4 through the plug plate 7, so that the display board 4 is stored in the storage slot 3. The retractable structural design can not only protect the idle display board 4, but also when the display board 4 is completely retracted, the upper end surface of the cabinet 1 can still remain horizontal, which is conducive to teaching staff writing at the upper end of the cabinet 1.

[0024] The storage slot 3 is provided with an insert plate 7, and the storage slot 3 is provided with a toothed plate transmission member for adjusting the height of the insert plate 7. The upper end of the insert plate 7 is rotatably connected to the display board 4. The connection between the display board 4 and the insert plate 7 is provided with a bolt positioning member for limiting the rotation of the display board 4. The display board 4 includes a first display area 41 and a second display area 42, and the first display area 41 and the second display area 42 are respectively placed on the front and back of the first display area 41. After the teaching staff writes the content on the first display area 41 of the display board 4, the display board 4 can be turned over after the bolt positioning member is released to rotate the display board 4. After the display board 4 is turned over, the user does not need to move the cabinet 1, and the first display area 41 with the content can be facing the students, which is convenient and practical.

[0025] More specifically, a slot seat 10 is provided at the lower end of the plug board 7, the slot seat 10 is sleeved on the outer side of the plug board 7, the slot seat 10 is slidably connected to the plug board 7, and the lower end of the slot seat 10 is fixedly connected to the bottom wall of the storage slot 3. When the toothed plate transmission member drives the plug board 7 to rise and fall, the plug board 7 will slide along the inner side wall of the slot seat 10, and the slot seat 10 guides the plug board 7 by slidingly cooperating with the plug board 7, so that the plug board 7 will not deviate when it is raised or lowered.

[0026] About the gear plate transmission part: the gear plate transmission part includes a positioning sleeve 12, a gear 8, a gear plate 9 and a motor 6. The positioning sleeve 12 is sleeved on the upper end of the plug plate 7, the positioning sleeve 12 is fixedly connected to the plug plate 7, the gear plate 9 is placed on one side of the plug plate 7, the upper end of the gear plate 9 is fixedly connected to the positioning sleeve 12, the gear 8 is placed on one side of the gear plate 9, the gear 8 is meshed with the gear plate 9, the motor 6 is installed on the outside of the cabinet 1, and the output end of the motor 6 is fixedly connected with the gear 8. The motor 6 drives the gear 8 to rotate, and the gear 8 is meshed with the gear plate 9 during the rotation. When the gear 8 rotates counterclockwise, the gear plate 9 falls, and the plug plate 7 also falls. When the gear 8 rotates clockwise, the gear plate 9 rises, and the plug plate 7 also rises.

[0027] Of course, in addition to using the motor 6 to control the rotation of the gear 8, the gear 8 can also be rotated by a hand crank structure for manual control. The advantage of manual control is that there is no need to consider the power supply problem. I will not explain it in detail here.

[0028] The bolt positioning member is also arranged at the lower end of the display board 4, which is used to limit the display board 4 from rotating at the upper end of the plug board 7, so that the teaching staff can correctly write the content on the display board 4. Specifically, the bolt positioning member includes a bolt plate 14, which is placed on one side of the positioning sleeve 12, and the bolt plate 14 is fixedly connected to the lower end of the display board 4. The bolt plate 14 is equipped with a positioning bolt 15, which passes through the bolt plate 14 and is threadedly connected with the thread groove 13 provided on the outer side of the positioning sleeve 12. The outer side of the positioning sleeve 12 has a plurality of thread grooves 13, and each thread groove 13 is evenly arranged in the circumferential direction of the axis of the positioning sleeve 12. The display board 4 can rotate at the upper end of the plug board 7, and the bolt plate 14 is fixed at the lower end of the display board 4. When the display board 4 rotates, the bolt plate 14 will also rotate around the axis of the positioning sleeve 12. When the position of the display board 4 is locked, the positioning bolt 15 assembled on the bolt plate 14 is matched with one of the thread grooves 13 on the outer side of the positioning sleeve 12, and the positioning bolt 15 can be screwed into it. High flexibility.

[0029] When the display board 4 falls into the storage groove 3, the tooth plate 9 fixed with the positioning sleeve 12 will also fall down. In order to avoid the tooth plate 9 from interfering with the bottom wall of the storage groove 3, a slot 11 is provided at the bottom of the storage groove 3, and the slot 11 is placed below the tooth plate 9. The tooth plate 9 after falling will be inserted into the slot 11, and the slot 11 will store the tooth plate 9.

[0030] In a preferred embodiment, the back of the cabinet 1 is provided with an arc-shaped concave surface 5, which extends to the upper end surface of the cabinet 1. During teaching, the arc-shaped concave surface 5 provided on the back of the cabinet 1 can enable the teaching staff to be closer to the display board 4, which is convenient for the teaching staff to write.

[0031] The working principle of the present application is as follows: when the display board 4 is in use, the gear transmission member controls the plug board 7 to move upward, and the plug board 7 lifts the display board 4 upward along the storage slot 3 during the movement, so that the display board 4 is mounted on the upper end of the cabinet 1.

[0032] When the display board 4 is idle, the gear transmission member will pull the display board 4 through the plug plate 7, so that the display board 4 is stored in the storage slot 3. The retractable structural design can not only protect the idle display board 4, but also keep the upper end surface of the cabinet 1 horizontal when the display board 4 is completely retracted, which is conducive to teaching staff to write on the upper end of the cabinet 1.

[0033] After the teaching staff writes the content on the first display area 41 of the display board 4, the display board 4 can be turned over by releasing the rotation of the bolt positioning member on the display board 4. After the display board 4 is turned over, the user does not need to move the cabinet 1, and the first display area 41 with the content can face the students, which is convenient and practical.
