Description

Technical Field

[0001] The invention relates to the technical field of pictorial display, and in particular to a long-length educational pictorial display device. Background Art

[0002] In the current education field, there are various ways to display pictorials, but traditional display methods often have problems such as fixed display angles and heights, and inconvenient adjustment. These problems not only limit the audience's viewing experience, but also affect the delivery of educational effects.

[0003] Specifically, traditional pictorial display devices usually only have a single display angle and height, and cannot be flexibly adjusted according to the needs of the audience or site conditions. In this way, viewers in different directions may not be able to clearly see the content of the pictorial on the display board, resulting in obstruction of information transmission. In addition, for some long pictorials, due to the fixed display height, the audience may need to look up or down for a long time to watch, which not only increases the viewing difficulty of the audience, but also may cause a burden on the audience's cervical spine. In order to solve the above problems, some display devices with adjustable angles and heights have appeared in the prior art. However, these devices are often complex in structure, cumbersome to operate, and require large and different energy sources to drive. This not only increases the cost of use, but may also reduce the reliability and stability of the device. For this reason, we propose a long-format educational pictorial display device.

A first mounting tube 20 connected to the interior of the oil supply box 8 is provided on the oil supply box 8, and a second mounting tube 31 connected to the interior of the oil supply box 8 is provided below the adjustment tube 3. The first displacement block 25 is slidably connected to the inner bottom and the inner bottom of the first groove 21. The reciprocating screw 17 is fixedly connected to the inner ring of the first one-way bearing 29, and the outer ring of the first one-way bearing 29 is fixedly connected to the gear 24. The design of the first one-way bearing 29 enables the reciprocating screw 17 to only drive the gear 24 in one direction, thereby ensuring the accuracy of the transmission. One end of the first mounting tube 20 connected to the oil supply box 8 is located below the oil supply plug 35, and a connector 30 is provided between the first mounting tube 20 and the second mounting tube 31.

[0021] When the present invention is used, in the initial state, the first displacement block 25 abuts against the inner wall of the end of the first groove 21 away from the second long block 14, and the second displacement block 28 abuts against the inner wall of the end of the second groove 22 away from the first long block 12. By setting the display board 4, the educational pictorial can be displayed. When the display angle needs to be adjusted, the adjustment motor 5 is started to make the rotating shaft 34, the first plate body 6 and the second plate body 7 move along the attached Figure 4 When the first adjusting rod 10 rotates counterclockwise, the first disk body 6 drives the first adjusting rod 10 to rotate counterclockwise. When the first adjusting rod 10 rotates counterclockwise, the first adjusting rod 10 will contact one side of the second adjusting rod 11. At this time, because the second displacement block 28 abuts against the inner wall of one end of the second groove 22, the first long block 12 will not move in the direction close to the second long block 14. In this way, the first displacement block 25 will move in the first groove 21 in the direction close to the second long block 14, and the second spring 32 will be compressed. Subsequently, as the first adjusting rod 10 continues to rotate, the first adjusting rod 10 and the second adjusting rod 11 can be separated from each other, and the elastic force generated by the compression of the second spring 32 causes the first The displacement block 25 is reset, and finally, as the first adjusting rod 10 continues to rotate, the first adjusting rod 10 will cooperate with the first adjusting groove 18, and the second disk body 7 will cooperate with the second adjusting groove 19, so that the third disk body 9 can rotate clockwise by a certain angle. When the third disk body 9 rotates clockwise, the inner ring and the outer ring of the second one-way bearing 38 are locked with each other, so that the direction-adjusting tube 3 can rotate clockwise. Because the adjusting plug 36 is a cube, the connecting rod 13 and the display board 4 can rotate clockwise by a certain angle. In this way, the display angle can be adjusted so that people in different directions can view the pictures on the display board 4 according to needs, which is highly practical. When the display height needs to be adjusted, the adjusting motor 5 is started to move the rotating shaft 34, the first tray 6 and the second tray 7 along the upper surface. Figure 4When the third disk body 9 rotates counterclockwise, the inner ring and the outer ring of the second one-way bearing 38 rotate idly, and the direction-adjusting tube 3 will not rotate, that is, the display board 4 will not rotate. Then, as the first adjusting rod 10 continues to rotate, the first adjusting rod 10 will cooperate with the first adjusting groove 18, and the second disk body 7 will cooperate with the second adjusting groove 19, thereby enabling the third disk body 9 to rotate counterclockwise by a certain angle. When the third disk body 9 rotates counterclockwise, the inner ring and the outer ring of the second one-way bearing 38 will rotate idly, and the direction-adjusting tube 3 will not rotate, that is, the display board 4 will not rotate. Then, as the first adjusting rod 10 continues to rotate, the first adjusting rod 10 will cooperate with the second adjusting groove 19. The other sides of the two adjusting rods 11 are in contact with each other. At this time, because the first displacement block 25 is against the inner wall of the end of the first groove 21 away from the second long block 14, the first displacement block 25 cannot move in the first groove 21 in the direction away from the second long block 14, so that the second adjusting rod 11, the first long block 12, the auxiliary rod 26, the second displacement block 28 and the rack 16 can be synchronously moved in the direction away from the gear 24. The first spring 27 is compressed, and when the rack 16 moves, it is meshed with the gear 24 through the rack 16, so that the gear 24 can rotate in one direction. When the inner and outer rings of the first one-way bearing 29 are locked, the reciprocating screw 17 rotates in one direction, so that the oil supply block 15 can move back and forth up and down. By setting the oil supply rod 23, the oil supply plug 35 can move back and forth up and down. When the oil supply plug 35 moves back and forth up and down, the hydraulic oil in the oil supply box 8 will be squeezed into the adjustment tube 3 through the first mounting tube 20 and the second mounting tube 31, or the hydraulic oil in the adjustment tube 3 will be sucked into the oil supply box 8 through the second mounting tube 31 and the first mounting tube 20, so that the adjusting plug 36 can move upward or downward, which can The connecting rod 13 and the display board 4 can be moved upward or downward, so that the display height can be adjusted. As the first adjusting rod 10 continues to rotate clockwise, the first adjusting rod 10 will no longer contact the second adjusting rod 11. The elastic force generated by the compression of the first spring 27 can reset the second adjusting rod 11, the first long block 12, the auxiliary rod 26, the second displacement block 28 and the rack 16, so that the gear 24 can rotate in the other direction. However, at this time, the inner and outer rings of the first one-way bearing 29 are idle, and the reciprocating screw 17 does not rotate.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
