[0002] In the teaching of accounting, the physical display of vouchers (such as invoices, checks, account books, etc.) is a key link to help students understand business processes, filling specifications and audit points. Traditional teaching mostly adopts the following methods: sticking vouchers on hard display boards and hanging them on blackboards or walls, but the display boards are large and cannot be folded, resulting in storage difficulties, and the amount of information displayed on one side is limited; vouchers are classified and stored in loose-leaf folders, and they need to be searched page by page during teaching, which is cumbersome and cannot be displayed simultaneously from multiple angles. Although high-definition images can be displayed through electronic projection, they lack the physical touch. It is difficult for students to perceive the physical characteristics of the voucher material, seal details, etc., which affects practical cognition.

[0003] Therefore, the existing voucher management devices used in accounting professional teaching still have the following defects to be solved: traditional voucher management devices often use rigid frames to ensure stability, resulting in a large storage volume (thickness > 30cm), which is difficult to quickly transfer between classrooms, especially during the transfer process, it is inconvenient to carry. In addition, the fixed display boards cannot be rotated or unfolded in layers, and teachers need to frequently change the display boards or manually adjust the position of the vouchers, interrupting the continuity of teaching. Moreover, the existing voucher management devices rely on nails, tapes and other fixing methods, which are easy to damage the blackboard surface and cannot be adapted to teaching boards of different materials (such as metal whiteboards, glass blackboards).

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] In order to enable those skilled in the art to better understand the solution of the present application, 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 only 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 those skilled in the art without creative work should fall within the scope of protection of the present application.

[0047] See also Figure 1-10 , the embodiment provided by the present invention:

[0048] Example 1

[0049] like Figure 1-Figure 2 As shown, a voucher management device for accounting professional teaching includes multiple display boards 1 for displaying vouchers to students. The display board 1 is a display board for displaying various vouchers used in accounting professional teaching for students. In order to facilitate the portability and transfer of the voucher management device without taking up space, the display board 1 includes a fixed frame 11 and a rotating plate 12. One end of the rotating plate 12 is integrally formed with the bottom surface of the fixed frame 11. The fixed frame 11 is fan-shaped. The other end side walls of the multiple rotating plates 12 are penetrated with shaft holes. The multiple rotating plates 12 are overlapped and installed through a fixing mechanism 3 inserted and installed in the shaft hole;

[0050] Specifically, the fixing mechanism 3 includes a second limit plate 31, a fixing rod 32, a washer 34 and a nut 35, wherein the axial hole of one of the rotating plates 12 is a cross hole, and a sliding key is arranged on the side wall of the fixing rod 32. The fixing rod 32 is connected to the cross hole key of one of the rotating plates 12 through a sliding member on the side wall, and a shaft sleeve 33 is installed in the axial hole of the remaining rotating plates 12, and the shaft sleeve 33 is sleeved on the side wall of the fixing rod 32. One end of the fixing rod 32 is fixedly connected to the second limit plate 31, and the other end of the fixing rod 32 is installed in the axial hole of the ratchet shaft seat 6. The side wall of the other end of the fixing rod 32 is threadedly connected with a nut 35, and the side wall of the fixing rod 32 between the nut 35 and one of the rotating plates 12 is sleeved with a washer 34.

[0051] Among them, multiple display boards 1 can be rotated along the fixing mechanism 3 to unfold in a disc shape. On the one hand, the multiple display boards 1 can classify and store different types of vouchers. On the other hand, multiple vouchers can be displayed to students as much as possible for viewing and understanding when teaching is needed. Multiple display boards 1 are connected in series on the fixing rod 32 through the axial hole of the rotating plate 12. The display boards 1 with cross holes are fixed to the fixing rod 32 and cannot be rotated at will. The remaining display boards 1 are freely rotated on the fixing rod 32 through the smooth inner wall of the shaft sleeve 33. When rotating, the remaining display boards 1 are rotated clockwise to finally form a concentric disc-shaped layout. Each display board 1 can fix a type of voucher (such as invoices, checks, account books), and the teaching content can be quickly switched by rotation.

[0052] like Figure 6-Figure 7 As shown, in order to ensure the stability of multiple display panels 1 in the unfolded state and prevent them from shaking, a slide groove 13 is provided on the top of the fixed frame 11, and a slide column 14 is fixedly connected to one end of the slide groove 13, and a second limit piece 4 is slidably connected to the bottom surface of the other end of the slide groove 13, wherein the slide column 14 of one fixed frame 11 is slidably connected in the slide groove 13 of the other fixed frame 11, and slides to the other end of the slide groove 13 and is dislocated and resisted by the second limit piece 4, and the second limit piece 4 includes a slider 41, and a second yielding groove 42 is provided in the slide groove 13, and a limited block 44 is integrally formed at both ends of the bottom of the slider 41, and the slider 41 and the limit block 44 are both slidably connected in the second yielding groove 42, and holes are respectively provided at both ends of the bottom surface of the limit block 44, and the holes are equipped with a second spring 43, and the side walls on both sides of the top of the slider 41 are inwardly concave arc structures, and the top of the slider 41 is outwardly convex arc structures.

[0053] When the display board 1 is unfolded to the maximum angle, the slide column 14 of the adjacent display board 1 slides to the end along the slide groove 13, and the slide column 14 contacts the arc surface at the top of the slider 41, pressing the slider 41 downward to make it descend along the second give way groove 42, compressing the second spring 43; when the slide column 14 passes the top of the slider 41, the spring rebounds and pushes the limit block 44 to rise, forming a physical position to prevent the slide column 14 from retreating, pinching the edge of the display board 1 and slightly lifting it upward, the slide column 14 disengages from the limit block 44, and the display board 1 can be freely rotated and folded, so that multiple display boards 1 can be unfolded and folded, so as to facilitate the transfer and storage when not teaching, and also ensure the display of various certificates during teaching.

[0054] like Figure 3 As shown, the fixing frame 11 is provided with a mounting groove 15 inside, and the credential loading plate 2 is rotatably connected in the mounting groove 15, and the top and bottom ends of the credential loading plate 2 are integrally formed with a rotating shaft 24, and the top and bottom surfaces of the mounting groove 15 are provided with an axial hole, and the rotating shaft 24 is rotatably connected in the axial hole, and the side wall of the credential loading plate 2 is penetrated to provide a first loading cavity 21 and a second loading cavity 22 for inserting a credential;

[0055] The first loading cavity 21 can be inserted with A4-sized documents (such as contracts), and the second loading cavity 22 is suitable for small-sized documents (such as checks), so as to facilitate the classification and management of different documents. It is worth noting that the document loading plate 2 is a transparent acrylic plate, and the contracts or documents in the first loading cavity 21 and the second loading cavity 22 can be directly seen through the document loading plate 2.

[0056] like Figure 3-Figure 5 As shown, in order to prevent the credential loading plate 2 from rotating in the installation slot 15 during the movement, the side walls of the credential loading plate 2 are slidably engaged with the side walls of the installation slot 15 through the first limiting member 23, and the side walls of the installation slot 15 are respectively provided with arc grooves 151, the first limiting member 23 includes a clamping head 231 and a first spring 233, and the side walls of the credential loading plate 2 are respectively provided with first clearance grooves 232, the clamping head 231 is slidably connected in the first clearance groove 232 through the first limiting plate 234 at the bottom, and the first spring 233 is arranged in the gap between the first limiting plate 234 and the first clearance groove 232;

[0057] The ends of the clamping head 231 exposed on the two side walls of the certificate loading plate 2 are set to be spherical, and the ends of the clamping head 231 are slidably engaged with the inside of the arc surface groove 151;

[0058] When the credential loading plate 2 and the fixed frame 11 are in the same plane, the first spring 233 pushes the spherical end of the clamping head 231 to embed into the arc groove 151 of the mounting groove 15, forming a "ball-socket pair" structure. The friction force prevents the loading plate from rotating freely. When the credential loading plate 2 rotates along the rotating shaft 24, the clamping head 231 retracts into the first yielding groove 232, releasing the clamping connection with the arc groove 151, so that the loading plate can be rotated to replace the credential. Even if the device is tilted during movement, the clamping head 231 can still lock the angle of the loading plate to prevent the credential from being scattered.

[0059] Example 2

[0060] like Figure 8-Figure 9 As shown, on the basis of Example 1, in order to facilitate students to view the credential management device, a ratchet shaft seat 6 is installed at the tail end of the fixing mechanism 3, and the ratchet shaft seat 6 is fixed to one side wall of the mounting mechanism 5 by screws, and an adsorption mechanism is fixed to the other side wall of the mounting mechanism 5.

[0061] The mounting mechanism 5 includes a mounting frame 51, which is disc-shaped and has a plurality of hollow grooves on its side wall. The center of one side wall of the mounting frame 51 is fixed to the ratchet shaft seat 6 by screws. When the plurality of display panels 1 are rotated and unfolded clockwise, the plurality of display panels 1 rotate along the fixing rod 32, causing the ratchet teeth of the fixing rod 32 in the ratchet shaft seat 6 to rotate, the ratchet pawl spring is compressed, and the ratchet teeth slide over the ratchet pawl, allowing one-way rotation.

[0062] The top surface of the installation frame 51 is fixedly connected to one end of the indicator plate 52 , the other end of the indicator plate 52 is a pointed tip 521 , and another point of the indicator plate 52 is placed outside the plurality of display panels 1 .

[0063] During the teaching process, the multiple display boards 1 can be rotated to make the pointed ends 521 of the indicator board 52 point to the vouchers in different areas, so that students can answer questions related to the vouchers in the area, which also increases the fun of the teaching process.

[0064] The adsorption mechanism includes a mounting column 53 and a suction cup 54 . The other side wall of the mounting frame 51 is threadedly connected to one end of the mounting column 53 at equal angles along a circle around the center of the circle, and the other end of the mounting column 53 is threadedly connected to the suction cup 54 .

[0065] The suction cups 54 are adapted to ordinary blackboards without magnetism, so that the credential management device can be adsorbed on the blackboard through multiple suction cups 54, and can explain and teach different credentials facing students for the convenience of students to watch.

[0066] Example 3

[0067] like Fig.10As shown, on the basis of Example 2, what is different from Example 2 is that, depending on the material of the base blackboard, if the suction cup 54 cannot be well adsorbed on the blackboard, the adsorption mechanism can also be replaced with a magnetic adsorption method, and the adsorption mechanism includes a mounting column 53, a mounting plate 55 and a magnet 56. The side wall on the other side of the mounting frame 51 is threadedly connected to one end of the mounting column 53 at equal angles along a circle around the center of the circle, and the other end of the mounting column 53 is threadedly connected to the center of one side wall of the mounting plate 55. A groove is provided on the other side wall of the mounting plate 55, and the magnet 56 is bonded in the groove.

[0068] The magnetic suction method is adapted to the blackboard with magnetic suction, so that the credential management device can be adsorbed on the blackboard, and the magnet 56 is recessed in the groove of the mounting plate 55 to avoid direct contact with the surface of the blackboard, prevent scratches or magnetic powder from falling off and contamination, and can still be firmly adsorbed on the frameless metal whiteboard, solving the limitation of the traditional suction cup 54 relying on a smooth surface.

[0069] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
