Description

Technical Field

[0001] This invention relates to the field of display device technology, specifically to a psychological knowledge display device with a convenient function of changing display paper. Background Technology

[0002] When promoting psychological knowledge, display devices are used to show exhibits. However, the current use of psychological knowledge displays still has the following problems:

[0003] 1. In the current psychological knowledge display device, when replacing the display paper on both sides of the display device, it is necessary to open the shell on both sides of the display device. Therefore, there are many operation steps when replacing the display paper, resulting in low efficiency of display paper replacement.

[0004] 2. Current psychological knowledge display devices generally have a fixed display area when displaying the paper, so it is impossible to adjust the number of display areas according to the display needs, which causes inconvenience in use.

[0005] 3. Current psychological knowledge display devices require different display surfaces depending on the size of the display paper. However, the current display devices are not easy to adjust the size of the display surface accordingly, which causes inconvenience in use.

[0006] 4. Currently, psychological knowledge display devices generally use adhesive to fix the display paper. This is not only inconvenient to operate, but also cannot guarantee the firmness of the fixation, so there is a possibility that the display paper will fall off.

[0007] 5. Current psychological knowledge display devices require multiple light tubes for lighting the display paper, which not only consumes a lot of electricity, but also takes up space inside the display device.

[0008] Therefore, a psychological knowledge display device with the function of easy paper replacement is needed to solve the above problems. Summary of the Invention

[0009] (a) Technical problems to be solved

[0010] To address the shortcomings of existing technologies, this invention provides a psychological knowledge display device with a convenient paper replacement function. This solves the problems of the need to open the casing on both sides of the display device to replace the paper, resulting in numerous steps and low efficiency. Furthermore, the fixed display surfaces prevent adjustment of the required number of surfaces according to display needs, causing inconvenience. Different paper sizes require different display surface sizes, but current devices do not allow for adjustments, further complicating usage. The paper is typically fixed using adhesive, which is inconvenient and lacks stability, potentially leading to paper detachment.

[0027] (III) Beneficial Effects

[0028] The beneficial effects of this invention are as follows:

[0029] 1. This psychological knowledge display device with convenient paper replacement function allows the protective frame to be removed when replacing the paper by connecting the circular groove and bolt on one of the four protective frames. At this time, the ring guide belt is supported by the support cylinder 1, support cylinder 2, rear main cylinder and front main cylinder. Rotating the rotating ring 1 or rotating ring 2 drives the rotating shaft 1 and rotating shaft 2 to rotate. At this time, the rear main cylinder and the front main cylinder drive the ring guide belt to rotate, so that the four display areas on the ring guide belt are rotated to the right front side of the display device. Then, by removing the protective frame on the right front side, the paper of the four display areas can be replaced. It is no longer necessary to disassemble and remove the protective frames in other directions. Therefore, it can effectively reduce the operation steps when replacing the paper and effectively improve the efficiency of paper replacement.

[0030] 2. This psychological knowledge display device, which features convenient paper replacement, connects the left and right positioning supports via an adjustable component, and further connects them via rear and front guide positioning components. When adjusting the number of display surfaces, the adjusting shaft can be rotated via rotating ring three. This rotation, through the meshing of bevel gear four and bevel gear three, drives the linkage shaft to rotate. The rotation of the linkage shaft, through the meshing of bevel gear two and two bevel gears one, drives the two threaded cylinders to rotate. When the two threaded cylinders rotate in either the forward or reverse direction, the two threaded cylinders can move closer together. The left and right vertical plates can be moved closer or further apart. When the left and right vertical plates move further apart, the two front and two rear display areas on the circular display belt can be adjusted from a right angle to a plane. This allows the display device to form a larger display surface between the four display areas, the two front display areas, and the two rear display areas. In other words, the display device can be adjusted from a square shape to a long strip. This allows the number of display surfaces to be adjusted according to the display needs when displaying the paper, making it more convenient to use.

[0031] 3. This psychological knowledge display device with convenient paper replacement function connects the left and right positioning supports through adjustable components, and also connects them through rear and front guide positioning components. When a larger display surface is formed between the two display areas on the front and the two display areas on the back of the device through the adjustable components, the device can be adjusted from a square shape to a long strip. After a larger display area is formed between the two display areas on the front and the two display areas on the back, a larger piece of paper can be displayed on either the front or the back display areas. In other words, the width of the paper can be doubled compared to before. This solves the problem that current psychological knowledge display devices do not allow for adjustments to the display surface size due to the different sizes of the paper, which causes inconvenience in use.

[0032] 4. This psychological knowledge display device with convenient paper replacement function uses multiple fixing parts set in each display area. When paper needs to be fixed, the magnetic block is taken out from the clamping groove by the pick-and-place block, separating the magnetic block from the magnetic sheet. Then, the transparent fixing strip and the ring display strip are separated by pulling a gap. The paper to be fixed can then be placed between the ring display strip and the multiple transparent fixing strips. The paper is clamped on the display area of ​​the ring display strip by the multiple transparent fixing strips. Then, the magnetic block is put into the clamping groove and is attracted to the magnetic sheet. This further clamps and fixes the paper to the ring display strip, thus fixing the paper to the ring display strip. This solves the problem that current psychological knowledge display devices generally use adhesive to fix the paper, which is not only inconvenient to operate, but also cannot guarantee the firmness of the fixation, so there is a possibility that the paper will fall off.

[0033] 5. This psychological knowledge display device, which features convenient paper replacement, utilizes a lighting system on its top side. A solar panel converts light energy into electrical energy, which is stored in a battery to power the lamps. When the light sensor detects dim lighting, the control box receives a signal and activates the lamps. Since the two lamps are horizontally positioned in the middle of the display device, the light source illuminates the front and rear annular display strips, thus illuminating the four display areas on the annular display strips. This solves the problem that current display devices require multiple lamps for lighting the paper, which not only consumes a lot of electricity but also takes up internal space.

When it is necessary to fix the displayed paper using the multiple fixing components 8 installed in each display area 73, the magnetic block 83 is removed from the clamping groove 82 by using the pick-and-place block 85, thus attaching the magnetic block 83 to the magnetic sheet 71. After separating the sheet 84, the transparent fixing strip 81 and the annular display strip 71 can be separated by pulling to create a gap. Then, the display paper that needs to be fixed can be placed between the annular display strip 71 and multiple transparent fixing strips 81. The display paper is clamped on the display area 73 of the annular display strip 71 by multiple transparent fixing strips 81. Then, the magnetic block 83 is placed into the clamping groove 82 and attracted to the magnetic sheet 84. This further clamps and fixes the display paper by sticking the transparent fixing strip 81 and the annular display strip 71 together, thus fixing the display paper on the annular display strip 71.

[0055] The lighting device 9 includes a top plate 91, which is fixedly installed between the left vertical plate 11 and the right vertical plate 21. A solar panel 93 is installed on the top plate 91 via a mounting plate 92. A battery 94 and a control box 95 are installed in the middle of the top plate 91. A light source sensor 96 is installed at the top of the right vertical plate 21. A side plate 97 is installed on the top side between the left vertical plate 11 and the right vertical plate 21. Lamp tubes 98 are installed on both the front and rear sides of the side plate 97. The solar panel 93 can convert light energy into electrical energy and store it in the battery 94, which can provide power to the lamp tubes 98. When the light source sensor 96 detects that the light is dim, the control box 95 receives a signal and starts the lamp tubes 98. At this time, since the two lamp tubes 98 are horizontally installed in the middle of the display device, the light source will illuminate the front and rear annular display strips 71, thereby illuminating the four display areas 73 on the annular display strips 71.

[0056] The protective device 10 includes four protective frames 102. A cover plate 103 is fixedly installed at the top of each protective frame 102. A transparent plate 104 is fixedly installed inside each protective frame 102. Two L-shaped support plates 101 are installed at the top of each of the four protective frames 102. Two bolts 105 are fitted onto the protective frame 102 on the right front side through a circular groove 106. The two bolts 105 are fixedly installed on the cover plate 103. The L-shaped support plates 101 are fixedly connected to the corresponding upper connecting rod 510 and connecting rod 610, respectively. By fitting the circular groove 106 on one of the four protective frames 102 with the bolts 105, the protective frame 102 can be removed when changing the unfolded paper. At this time, the support cylinder 14, support cylinder 24, rear main cylinder 59 and front main cylinder 69 support the annular guide belt 71. Rotating the rotating ring 15 or rotating ring 25 will drive the rotating shaft 13 and rotating shaft 23 to rotate. At this time, the rear main cylinder 59 and the front main cylinder 69 will drive the annular guide belt 71 to rotate, so that the four display areas 73 on the annular guide belt 71 are rotated to the right front side of the display device. Then, by removing the protective frame 102 on the right front side, the display paper of the four display areas 73 can be replaced. It is no longer necessary to disassemble and remove the protective frames 102 in other directions. Therefore, the operation steps when replacing the display paper can be effectively reduced.

[0057] The operation steps of this invention are as follows:

[0058] By connecting the circular groove 106 on one of the four protective frames 102 with the bolt 105, the protective frame 102 can be removed when changing the paper. At this time, the support cylinder 14, support cylinder 24, rear main cylinder 59 and front main cylinder 69 support the annular guide belt 71. Rotating the rotating ring 15 or rotating ring 25 will drive the rotating shaft 13 and rotating shaft 23 to rotate. At this time, the rear main cylinder 59 and the front main cylinder 69 will drive the annular guide belt 71 to rotate, so that the four display areas 73 on the annular guide belt 71 are rotated to the right front side of the display device. Then, by removing the protective frame 102 on the right front side, the paper of the four display areas 73 can be replaced. It is no longer necessary to disassemble and remove the protective frames 102 in other directions. Therefore, the operation steps when changing the paper can be effectively reduced.

[0059] The left and right positioning supports are connected by the rear guide positioning component 5 and the front guide positioning component 6. When the number of display surfaces of the unfolded paper needs to be adjusted, the adjusting shaft 315 can be rotated by rotating the rotating ring 316. At this time, the meshing of the bevel gear 4 314 and the bevel gear 313 can drive the linkage shaft 311 to rotate. When the linkage shaft 311 rotates, the meshing of the bevel gear 2 310 and the two bevel gears 1 39 can drive the two threaded cylinders 33 to rotate. When the two threaded cylinders 33 rotate in the forward or reverse direction, the two threaded columns 34 can move closer or further away from each other, thereby pushing the left vertical plate 11 and... The right vertical plates 21 can move closer or further apart from each other. When the left vertical plate 11 and the right vertical plate 21 move further apart from each other, the two front display areas 73 and the two rear display areas 73 on the annular display belt 71 can be adjusted from a right angle to a plane. This allows the display device to form a larger display surface between the four display areas 73, the two front display areas 73, and the two rear display areas 73. In other words, the display device can be adjusted from a square shape to a long strip shape. This allows the number of display surfaces to be adjusted according to the display needs when displaying the paper.

[0060] By connecting the left and right positioning supports through the rear guide positioning component 5 and the front guide positioning component 6, and by adjusting the component 3 to form a larger display surface between the two display areas 73 on the front side and the two display areas 73 on the rear side of the display device, the display device is adjusted from a square shape to a long strip shape. After forming a larger display area between the two display areas 73 on the front side and the two display areas 73 on the rear side, a larger display paper can be displayed on the two display areas 73 on the front side or the two display areas 73 on the rear side. That is, the width of the display paper can be doubled compared to the previous one.

[0061] By using multiple fasteners 8 set on each display area 73, when it is necessary to fix the display paper, the magnetic block 83 is taken out from the clamping groove 82 by the pick-and-place block 85, and the magnetic block 83 is separated from the magnetic sheet 84. Then, the transparent fixing strip 81 and the circular display strip 71 can be separated by pulling a gap. Then, the display paper to be fixed can be placed between the circular display strip 71 and multiple transparent fixing strips 81, so that the display paper is clamped on the display area 73 of the circular display strip 71 by multiple transparent fixing strips 81. Then, the magnetic block 83 is placed into the clamping groove 82 and attracted to the magnetic sheet 84, so that the transparent fixing strip 81 and the circular display strip 71 can be attached together to further clamp and fix the display paper, thus fixing the display paper on the circular display strip 71.

[0062] The solar panel 93 can convert light energy into electrical energy and store it in the battery 94, which can provide power to the lamp tube 98. When the light source sensor 96 detects that the light is dim, the control box 95 receives the signal and starts the lamp tube 98. At this time, since the two lamp tubes 98 are horizontally set in the middle of the display device, the light source will illuminate the front and rear annular display strips 71, thereby illuminating the four display areas 73 on the annular display strips 71.
