Technical Field

[0001] The present invention relates to the technical field of literary work display, and in particular to a multi-directional display device for literary works. Background Art

[0002] Literary works refer to creative achievements that use language and text as a medium to reflect social life, express thoughts and emotions, explore human nature and philosophy through artistic expression, and have aesthetic value. A literary work display device is a comprehensive system or equipment that uses technical means and creative design to present the content, background, artistic value, etc. of literary works to the audience in a multi-sensory, interactive, and immersive manner. Therefore, it is widely used in museums and exhibition halls, libraries and schools, cultural activities and festivals, and tourist attractions. When existing display devices display literary works, most of them directly place the literary works inside the display devices, but their display positions are uniform and fixed, which is not convenient for different groups of people to watch and use, thus affecting the later viewing effect and having poor practicality.

[0003] In order to overcome the above-mentioned defects, prior art 1 (application number CN202021294420.2, Chinese patent application date 2020-07-03) is a display device for literary works. By setting up vertical poles, square blocks, threaded rods and adjusting nuts, the adjusting nuts are adjusted so that the height of the display board can be raised and lowered, which can meet the needs of viewers of different age groups or different heights to appreciate the displayed literary works. Prior art 2 (application number CN202322659167.6, Chinese patent application date 2023-09-30) is a display device for literary works. By placing the literary works at the rear end of the glass plate, the edges of the literary works are pressed and fixed by a movable pressing plate, and the positions of the movable pressing plate and the fixed plate can be adjusted, which is convenient for clamping and fixing literary works of different widths and thicknesses, so that the literary works are relatively flat when displayed, thereby making the display effect of the literary works better and the overall use effect better.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The present invention provides the following technical solution, a multi-directional display device for literary works: Embodiment 1, in order to solve the problem that the existing display device needs to be manually rotated to adjust the viewing angle, but this manual rotation adjustment method is very time-consuming and labor-intensive, and the display device may be damaged due to the complex steps of manual operation, thereby affecting the viewing of later personnel and having poor practicality, the present invention discloses: a base 1, and a moving wheel 2 arranged under the base 1, an electric telescopic frame 3 is rotatably installed inside the base 1, and a connecting seat 4 is installed above the electric telescopic frame 3, and four display frames 5 are installed on the outer screws of the connecting seat 4, such as Figure 1 and Figure 2 As shown, two rotating shafts 20 are rotatably installed inside the base 1, and the inner ends of the two rotating shafts 20 are connected to worm gears 19, and the left end rotating shaft 20 is connected to the output end of the drive motor 15, and the drive motor 15 is installed on the left side of the base 1. Two steel air pipes 10 are rotatably installed above the base 1, and a row of air nozzles 11 are evenly spaced on the outer surfaces of the two steel air pipes 10, and a display frame 5 is correspondingly provided above the row of air nozzles 11.

[0022] The outer side of the worm 19 is meshed with a worm wheel 21, and the worm wheel 21 is rotatably mounted inside the base 1, wherein the inner part of the worm wheel 21 is connected to the electric telescopic frame 3, and the inner part of the display frame 5 is rotatably mounted with a placement plate 8, and the outer surface of the placement plate 8 is provided with a row of horizontal frames 9, and the two sides of the placement plate 8 correspond to light strips 7, as shown in FIG. Figure 3-Figure 5 As shown, the two light strips 7 are symmetrically arranged about the vertical center line of the display frame 5. A sealing plate 6 is slidably installed inside the display frame 5, and the display frame 5 and the sealing plate 6 are made of transparent materials.

[0023] When the display device needs to be displayed in multiple directions, it is only necessary to start the driving motor 15 to drive the worm 19 connected to the inner ends of the two rotating shafts 20 to rotate. Figure 1 and Figure 2 As shown, the rotating worm 19 drives the worm wheel 21 to rotate inside the base 1. At this time, the electric telescopic frame 3 connected to the inside of the worm wheel 21 will simultaneously drive the connecting seat 4 connected above it to drive the four display frames 5 to rotate slowly, thereby realizing the multi-directional display of the four display frames 5 to improve the viewing effect of the crowd, such as Figure 5 and Figure 6 As shown, there is no need for complicated operation steps of manual rotation, and the display device will not be damaged due to the complicated steps of manual operation, so it is more practical.

[0024] The second embodiment differs from the first embodiment in that, when the display device is automatically rotating, the gas stored in the two gas storage bags 30 can be sealed and transported through two hoses to a row of gas nozzles 11 provided above the two steel gas pipes 10 for gas injection. The ejected gas can then be transported into the display frame 5 through the second air holes 18. At this time, the gas inside the display frame 5 is discharged to the outside of the display frame 5 through the first air holes 17. This prevents the moisture inside the display frame 5 from causing the paper of the literary work to absorb water and expand, break fibers, and cause curling, brittleness, or adhesion of the document edges. This improves the preservation integrity of the literary work. An arcuate groove 22 is formed on the outer surface of the rotating shaft 20, and a slide rod 23 is slidably connected to the interior of the arcuate groove 22, and a turntable 24 is connected to the rear end of the slide rod 23, and a movable frame 25 is meshed and connected to the lower part of the turntable 24 through a second rack 26. The two movable frames 25 are symmetrically slidably mounted on the interior of the base 1, and the two movable frames 25 are connected to an extrusion plate 27 on one side close to the base 1, wherein the two extrusion plates 27 are slidably mounted on the interior of the storage box 28, as shown in FIG. Figure 7 and Figure 8As shown, the two storage boxes 28 are symmetrically arranged about the vertical center line of the base 1, and the interiors of the two storage boxes 28 are provided with air storage airbags 30, and the outer side surfaces of the two air storage airbags 30 correspond to the extrusion plates 27, and the tops of the two air storage airbags 30 are sealed with steel air pipes 10 through hoses, a second air vent 18 is provided below the display frame 5, and the top of the second air vent 18 corresponds to the first air vent 17, wherein the first air vent 17 is provided above the display frame 5.

[0025] When the display device is automatically rotating, the arc grooves 22 on the outer surfaces of the two rotating shafts 20 will simultaneously drive the two sliding rods 23 to drive the two turntables 24 to swing. At this time, the two swinging turntables 24 will drive the two moving frames 25 to expand and move inside the base 1 through the two second racks 26. Figure 7 and Figure 8 As shown, at this time, the extrusion plates 27 connected to the outer ends of the two mobile frames 25 will squeeze and exhaust the gas storage bags 30 placed inside the two storage boxes 28, so that the two gas storage bags 30 can transport the exhausted gas through two hoses to a row of air nozzles 11 arranged on the surface of the two steel air pipes 10 for air jet processing, as shown in FIG. Figure 4 As shown, the four slowly rotating display frames 5 can be subjected to air jet dehumidification treatment, thereby preventing the paper of the literary works from absorbing water and swelling, breaking fibers inside the four display frames 5, and causing the edges of the literature to curl, become brittle or stick together. This can keep the paper dry, maintain its strength and flexibility, and extend the life of the literary works.

[0026] While the two rows of air nozzles 11 are performing air jet dehumidification, the air jetted out will be transported to the interior of the display frame 5 through the second air holes 18, and then the humid air inside the display frame 5 will be discharged through the first air holes 17. Figure 3 and Figure 4 As shown, the dehumidification effect of the four display frames 5 is improved, and moist gas is prevented from being stored inside the display frames 5 and affecting the display effect of later literary works.

[0027] The third embodiment differs from the second embodiment in that two movable frames 25 can be used to drive the two movable plates 13 to expand their positions. At this time, a row of first racks 14 provided on the upper surfaces of the two movable plates 13 will simultaneously drive the steel air pipes 10 connected to the two half gears 12 to rotate, thereby expanding the jet range of the row of air nozzles 11 above the two steel air pipes 10, thereby preventing the yellowing of literary works that have been affected by moisture, thereby maintaining the aesthetics of the literary works. A movable plate 13 is positioned and installed above the two movable frames 25, and the two movable plates 13 are both "L" shaped, and the top ends of the two movable plates 13 slide and extend to the upper outside of the base 1. A row of first racks 14 are provided above the two movable plates 13, and the two first racks 14 are meshed and connected to the steel air pipe 10 through the half gear 12, as shown in FIG. Figure 7 and Figure 8 As shown, the two half gears 12 are installed on the front side of the two steel air pipes 10, and the outer side surfaces of the two steel air pipes 10 are wrapped with one end of a torsion spring 29, and the two torsion springs 29 have the same structure, and the other ends of the two torsion springs 29 are connected to the base 1.

[0028] When the two moving frames 25 move back and forth, they will drive a row of first racks 14 set above the two moving plates 13 to drive the two half gears 12 to rotate. At this time, the two rotating half gears 12 will simultaneously drive a row of air nozzles 11 set on the surface of the two steel air pipes 10 to swing and spray. Figure 7 and Figure 8 As shown, in order to improve the jet range of the two rows of air nozzles 11, avoid the yellowing of the wet literary works, maintain the aesthetics of the literary works, and thus improve the dehumidification effect of the literary works, after the first rack 14 is separated from the half gear 12, the torsion spring 29 will elastically reset the position of the rotated steel air pipe 10 by its own elastic force, as shown in FIG. Figure 9 As shown, it is convenient to reset and swing a row of air nozzles 11, and finally the steel air pipe 10 after reset and swing can be reset and limited by the limit rod 16, so as to avoid the steel air pipe 10 from being over-reset, and the stability is better, thereby completing a series of tasks.

[0029] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
