Description

Technical Field

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

[0002] Ideological and political education is the primary content of China's spiritual civilization construction and one of the main ways to solve social contradictions and problems. The high-efficiency teaching board for ideological and political education is a device used for ideological and political education. It is widely used in various fields and places. Because ideological and political education mainly adopts display methods such as pasting and writing, which is different from other subjects that require continuous writing teaching, its structure is also very different from other types of teaching boards.

[0003] After searching, application number 201920716325.8 discloses a high-efficiency teaching board for ideological and political education, including a support plate, which is a hollow structure, and a vertical partition is fixedly connected to the center of the support plate, and rectangular openings are provided on the front side walls of the support plate on the left and right sides of the partition, and display boards are slidably connected to the left and right sides of the partition, and strip openings corresponding to the display boards are provided on the left and right side walls of the support plate, and a connecting groove corresponding to the display board is provided on the inner wall of the support plate, and a sliding mechanism is provided between the display board and the connecting groove, and a teaching board is fixedly connected to the support plate.

[0004] During use, the high-efficiency ideological and political teaching board in this patent application increases the blackboard writing area during teaching by stretching the display board to the outside of the support board, which is helpful for teachers to use. However, during such use, the device only increases the blackboard writing area on one side of the display board, but fails to fully utilize both sides of the display board, reducing the practicality of the device. Moreover, when the display board is stretched to the outside of the support board, the volume of the upper end of the device becomes larger, while the bottom support area of ​​the device fails to increase accordingly, resulting in reduced stability of the device. For this reason, we propose a new teaching device. Utility Model Content

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a new teaching device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new teaching device, including a supporting base and a teaching board which can be adjusted in height and is arranged above the supporting base. Storage slide grooves are symmetrically provided at the left and right ends of the teaching board. The two storage slide grooves are symmetrically and slidingly connected with installation frames. The two installation frames are rotatably connected with display boards. Auxiliary bases which can be adjusted left and right are symmetrically provided at the left and right ends of the supporting base. Auxiliary supporting mechanisms are provided on the two auxiliary bases. The auxiliary supporting mechanisms include supporting rollers which are symmetrically and rotatably connected to the front and rear ends of the bottom wall of the auxiliary base and auxiliary telescopic columns which are fixedly installed to the top wall of the auxiliary base.

[0007] Furthermore, support rollers are symmetrically rotatably connected to the front and rear ends of the bottom wall of the support base.

[0008] Furthermore, a vertical telescopic support column is fixedly mounted on the top wall of the support base, and a telescopic end on the top side of the telescopic support column is fixedly mounted on the middle part of the bottom wall of the teaching board.

[0009] Furthermore, vertical rotating shafts are fixedly installed in the middle of the upper and lower walls of the two display boards, and the ends of the four rotating shafts away from the two display boards are rotatably connected to the corresponding positions of the upper and lower inner walls of the two installation frames.

[0010] Furthermore, an operating handle is fixedly mounted on one side of the two mounting frames away from the teaching board.

[0011] Furthermore, the bottom walls of the two storage slide grooves are penetrated by linear through grooves, and the telescopic ends of the top sides of the two auxiliary telescopic columns respectively penetrate the two linear through grooves and are respectively fixedly installed on the sides of the bottom walls of the two installation frames that are close to each other.

[0012] Furthermore, the two supporting rollers and the four auxiliary rollers are all provided with brake pads.

[0013] Furthermore, positioning magnet blocks are fixedly embedded on the left and right side walls of the support base, and two positioning iron sheets corresponding to the positions of the two positioning magnet blocks are fixedly embedded on one side wall of the two auxiliary bases close to the support base.

[0016] 1. This novel teaching device is provided with a display board and an auxiliary supporting mechanism. When in use, the device is conveniently moved to a designated position through two supporting rollers and four auxiliary rollers. When the blackboard writing area of ​​the device needs to be increased, the two installation frames are driven to move out of the two storage slides by pulling the operating handle, and the two installation frames drive the two display boards to move out of the two storage slides, and the two display boards can be turned over by rotating the shaft rod as the axis, so that both sides of the two display boards can be used, thereby improving the practicality of the device, and when the two installation frames are moved out of the two storage slides, the two installation frames drive the two auxiliary bases to move away from the supporting base through the two auxiliary telescopic columns, thereby increasing the support area of ​​the device and improving the stability of the placement of the device.

[0017] 2. This novel teaching device is provided with a positioning magnet block and a positioning iron sheet. When the two mounting frames are completely retracted into the two storage slide grooves, the two auxiliary bases are respectively fitted with the left and right side walls of the supporting base. At this time, the magnetic force between the positioning magnet block and the positioning iron sheet makes the two auxiliary bases fixedly connected to the supporting base, thereby improving the stability of the device structure.
