Description

Technical Field

[0001] This utility model relates to the field of display stand technology, and more specifically, it relates to a portable display stand for intangible cultural heritage exhibitions. Background Technology

[0002] In the current field of cultural heritage protection and display, the display stand for intangible cultural heritage (ICH) exhibitions plays a crucial role as a key display device in the protection, display and dissemination of ICH works. However, existing display stand technology still has many shortcomings. These problems not only affect the display effect of ICH works, but may also cause potential damage to precious ICH works.

[0003] First, existing display stands for intangible cultural heritage exhibitions have significant shortcomings in air quality control. Many intangible cultural heritage works, such as traditional handicrafts and ancient books and documents, have extremely high requirements for the air quality of the display environment. These works often need to ensure air circulation while preventing the intrusion of external pollutants. Although some display stand designs adopt a semi-enclosed cabinet structure and are equipped with filter plates at the air inlet to block large foreign objects from entering the display area, this design still cannot effectively block fine dust particles. These fine dust particles can easily pass through conventional filter plates and enter the display area, eventually settling on the surface of the intangible cultural heritage works. Long-term accumulation of dust not only affects the aesthetics of the works but may also lead to the deterioration of the materials, such as corrosion, discoloration, or structural damage. This situation is particularly serious for some especially sensitive intangible cultural heritage works, such as ancient textiles and painted handicrafts, and may lead to irreversible damage.

[0004] Secondly, regarding dust control, although some display equipment has introduced active dust removal systems, such as using miniature air extraction devices to adsorb and remove small particulate dust from the air, these systems often overlook the diversity and uniqueness of intangible cultural heritage works in their design. Different types of intangible cultural heritage works have varying sensitivities to airflow speed due to differences in their materials, structures, and preservation conditions. For example, some lightweight paper or fiber products may require lower airflow speeds to avoid physical damage to the works; while some more robust stone or metal products may withstand higher airflow speeds. However, most existing display stands adopt a fixed airflow speed design, which cannot flexibly adjust the airflow speed according to the needs of different works. This one-size-fits-all design method may not only fail to achieve the best dust removal effect, but may also cause unnecessary stress and damage to some fragile intangible cultural heritage works. In the long run, this inappropriate airflow control may accelerate the degradation process of some intangible cultural heritage works, which violates the original intention of the display stands to protect cultural heritage.

[0005] Furthermore, in response to the aforementioned problems, some display equipment has improved the functionality of the display stand by introducing devices that can adjust the airflow speed. However, these improved designs still have serious stability issues in practical applications. These adjustment devices are usually under continuous airflow impact and are subject to long-term vibration and airflow pressure, making them prone to structural loosening and positional displacement. Such mechanical failures not only cause changes in the preset airflow speed, affecting the dust removal effect, but may also cause airflow instability, adversely affecting the display environment. More seriously, this instability may persist without the knowledge of exhibition staff, potentially endangering the safety of exhibits. In addition, due to the lack of real-time monitoring and automatic adjustment functions, even if changes in airflow speed are detected, manual intervention is required for readjustment, which increases the complexity of maintenance and labor costs.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a portable display stand for intangible cultural heritage exhibitions, which has the following advantages:

[0019] 1. The dust removal device effectively solves the problem of filtering fine dust in existing technologies through a combination design of air pump, processing box, air pipe and box cover. The air pump creates negative pressure inside the processing box through the air pipe, and through the optimized pipeline layout, it draws air and dust from inside the cabinet into water. This water washing filtration method can effectively capture fine particles, prevent dust from re-entering the display environment, and prevent fan blockage, greatly improving the air purification effect. The design of storing water in the processing box not only improves the dust removal efficiency, but also allows for long-term collection of settled dust, reducing the frequency of maintenance. This innovative dust removal method greatly improves the air quality of the display environment and effectively protects sensitive intangible cultural heritage works from dust pollution and potential material degradation.

[0020] 2. The speed control device employs a clever combination of a control sleeve, fixed pipe, suction pipe, linkage plate, linkage groove, linkage shaft, and movable shaft. This solves the problem of fixed suction speed in existing technologies, which cannot be adjusted according to the needs of different intangible cultural heritage works. By rotating the control sleeve, the linkage plate can be moved via the movable shaft, thereby changing the internal channel area of ​​the control panel and achieving precise adjustment of the airflow speed. The linkage hole diameter on the linkage plate is larger than the filter hole on the filter plate, effectively preventing clogging. This adjustable design allows the display stand to adapt to the special needs of different types of intangible cultural heritage works. It can provide a gentle airflow environment for fragile paper or fiber products, and provide a stronger dust removal effect for solid stone or metal products, greatly improving the adaptability and protective effect of the display stand.

[0021] 3. The self-locking mechanism, through the coordinated operation of the control plate, control hole, control sleeve, control rod, adapter slot, and adapter rod, effectively solves the problems of easy loosening and displacement of airflow regulating devices in existing technologies. After adjustment, the special design of the control rod and control plate can lock the position of the control sleeve, thereby fixing the control sleeve and preventing it from rotating accidentally. The adapter rod is firmly inserted into the adapter slot under the action of the adapter spring, further enhancing the stability of the structure. This multi-locking mechanism ensures that the airflow speed once set will not deviate due to vibration or long-term use, greatly improving the reliability and stability of the equipment. At the same time, the design of the self-locking mechanism also allows for quick unlocking and readjustment when needed, ensuring the stability of daily use while providing the necessary flexibility, effectively reducing the complexity of maintenance and labor costs.

[0031] Please see Figures 1-5A portable intangible cultural heritage exhibition stand includes a cabinet 1. A dust removal device is installed at the top of the cabinet 1. The dust removal device includes an air pump 2, a processing box 3, an air pipe 4, and a box cover 5. The box cover 5 is detachably installed on the top of the processing box 3. The air pipe 4, connected to the input end of the air pump 2, extends into the processing box 3, which contains two-thirds water. Another air pipe 4 is connected to the box cover 5, and its other end is connected to a speed control device. The speed control device includes a control sleeve 6, a fixed pipe 7, a suction pipe 8, a linkage plate 9, a linkage groove 10, a linkage shaft 11, and a movable shaft 12. The two ends of the control sleeve 6 are rotatably connected to the fixed pipe 7 and the suction pipe 8, respectively. The top end of the fixed pipe 7 is fixedly connected to the air pipe 4. The linkage plate 9 is connected to the movable shaft 12... The control sleeve 6 is rotatably connected, the linkage groove 10 is opened on one side of the suction pipe 8, the linkage shaft 11 is slidably arranged in the linkage groove 10, and the linkage shaft 11 is rotatably installed on the other side of the linkage plate 9. A self-locking mechanism is provided on the outside of the fixed pipe 7. The self-locking mechanism includes a control plate 13, a control hole 14, a control sleeve 15, a control rod 16, an adapter groove 17, and an adapter rod 18. The control plate 13 is rotatably installed on the outside of the fixed pipe 7, the control hole 14 is opened on the control plate 13, the control sleeve 15 is slidably sleeved on the outside of the fixed pipe 7, the control rod 16 is fixedly connected to one side of the control sleeve 15, multiple adapter grooves 17 are opened on the outer wall of the fixed pipe 7, and multiple adapter rods 18 are slidably arranged on the side wall of the control sleeve 6, with the inner end of the adapter rod 18 inserted into the adapter groove 17.

[0032] The top of the cabinet 1 is fixedly provided with a top block 19. The air pump 2 and the processing box 3 can be detachably installed on the top block 19. Three sides of the cabinet 1 are provided with observation windows 20, and one side of the cabinet 1 is provided with an opening and closing door 21.

[0033] A dust hood 22 is detachably provided below the top block 19. The top of the dust hood 22 is connected to the bottom of the dust suction pipe 8. A placement platform 23 is detachably provided inside the cabinet 1. Filter plates 24 are symmetrically provided on the side walls of the cabinet 1.

[0034] A ladder 25 is detachably provided on one side of the top block 19, and a brake caster 26 is detachably provided at the bottom of the cabinet 1.

[0035] In this embodiment, when the device is needed, the brake plate in the brake caster 26 first engages to limit the caster, then the cabinet 1 is pushed, causing the entire device to move via the brake caster 26 at the bottom. After moving to the designated position, the brake plate in the brake caster 26 locks the caster, preventing the device from moving. Then, the opening door 21 is opened, or one of the observation windows 20 is removed, allowing the intangible cultural heritage artwork to be stably placed on the placement platform 23. The opening door 21 is then closed, or the observation window 20 is reinstalled on one side of the cabinet 1. The opening door 21 can be locked using existing locks. Air then enters the cabinet 1 through the filter plate 24, where large foreign objects and flying insects are filtered out. The air, mixed with small dust particles, is blocked outside the cabinet 1 by the filter plate 24 and enters the cabinet 1 through the filter plate 24. Then, the air pump 2 is turned on. The air pump 2 draws the space between the water and the treatment tank 3 into a negative pressure state through the air pipe 4 connected to the input end. The air pipe 4 extends to the water surface. Then, the air pipe 4 set on the tank cover 5 sucks in the air and small dust particles in the cabinet 1 through the fixed pipe 7, the suction pipe 8, and the suction hood 22. The air pipe 4 extends below the water surface. Then, the air and small dust particles enter the water stored in the treatment tank 3. Then, the dust mixes with the water and settles to the bottom of the treatment tank 3. The air floats out of the water surface and is sucked in by the air pipe 4 connected to the input end of the air pump 2, and then discharged through the output end of the air pump 2.

[0036] Please see Figures 2-5 As a further implementation of the overall equipment: the linkage plate 9 has multiple linkage holes 27, and the diameter of the linkage holes 27 is larger than the diameter of the filter holes on the filter plate 24.

[0037] A rubber strip 28 is fixedly provided at one end of the suction pipe 8, and a corresponding slot 29 is provided on the inner side of the control sleeve 6, in which the rubber strip 28 is engaged.

[0038] An adapter spring 30 is provided on the outer side of the control sleeve 6, and the outer end of the adapter rod 18 is connected to the outer wall of the control sleeve 6 through the adapter spring 30.

[0039] A control spring 31 is movably sleeved on the outside of the control lever 16. One end of the control spring 31 is connected to the control sleeve 15, and the other end of the control spring 31 is in contact with the control plate 13.

[0040] More specifically, when the suction speed needs to be adjusted according to the characteristics of intangible cultural heritage products, facing the tall cabinet 1, staff can climb to the top of the top block 19 using the ladder 25. First, they rotate the control plate 13, which causes the control hole 14 to rotate. When the control hole 14 is concentric with the control rod 16, they push the control sleeve 15. The control sleeve 15 then causes the control rod 16 to slide into the control hole 14. The control sleeve 15 and the control plate 13 work together to compress the control spring 31, causing the adapter rod 18 to lose its limit. Then, rotating the control sleeve 15 causes the sliding mechanism on the side wall to... Multiple adapter rods 18 are moved, and then the inner wall of the adapter groove 17 on the outside of the fixed tube 7 presses against the inner end of the adapter rod 18. Due to the rounded corner design at the edge of the inner wall of the adapter groove 17 and the end of the adapter rod 18, the inner end of the adapter rod 18 slides out of the adapter groove 17, and the other end of the adapter rod 18 will drive the adapter spring 30 to stretch. At the same time, the control sleeve 6 will drive the linkage plate 9 to move through the movable shaft 12. Then, multiple linkage plates 9 will synchronously drive the linkage hole 27 to rotate. Since the diameter of the linkage hole 27 is larger than the diameter of the filter hole on the filter plate 24, the linkage hole 27 will not be blocked, and the other side of the linkage plate 9 will drive the linkage hole 27 to rotate. The moving linkage shaft 11 slides along the linkage groove 10, causing multiple linkage plates 9 to simultaneously open the linkage groove 10 outwards. This changes the cross-sectional area of ​​the opening inside the control sleeve 6, resulting in a change in the flow area and thus a change in the gas volume, thereby altering the pumping speed. After proper adjustment, the control sleeve 6 is stopped from rotating, and the adapter spring 30 causes the adapter rod 18 to slide back into the corresponding adapter groove 17. Then, the control sleeve 15 is released, and the control spring 31 pushes the control sleeve 15 to slide back into place. The control sleeve 15 then causes the control rod 16 to slide back into place. When the control spring 31 is fully reset, the control rod 16... 6 is no longer inserted into the control hole 14, and then the control plate 13 is rotated again, so that the control plate 13 drives the control hole 14 to rotate to a position that does not correspond to the control rod 16. Through the support of the control sleeve 15 by the control rod 16 and the control plate 13, and the preload applied by the control spring 31, the control sleeve 15 cannot easily slide. Then, the inner wall of the control sleeve 15 limits the outer end of the control rod 16, so that the control rod 16 cannot move. Then, the control rod 16 and the control groove cooperate to lock the control sleeve 6, so that the control sleeve 6 cannot rotate, thereby ensuring the stability of the adjusted structure and ensuring the stable operation of the dust removal work.

[0041] In summary, during the use or operation of the entire device: When the device needs to be used, firstly, the brake plate in the brake caster 26 engages to limit the caster, then the cabinet 1 is pushed, allowing the entire device to move via the brake caster 26 at the bottom. After moving to the designated position, the brake plate in the brake caster 26 locks the caster, preventing further movement. Then, the opening door 21 is opened, or one of the observation windows 20 is removed, allowing the intangible cultural heritage artwork to be stably placed on the placement platform 23. Then, the opening door 21 is closed, or the observation window 20 is reinstalled on one side of the cabinet 1. The opening door 21 can be locked using existing locks. Air then enters the cabinet 1 through the filter plate 24, absorbing large foreign objects. Flying insects are intercepted by filter plate 24 and kept outside the cabinet 1. Air mixed with small dust particles passes through filter plate 24 and enters the cabinet 1. Then, air pump 2 is turned on. Air pump 2 draws the space between water and treatment tank 3 into a negative pressure state through air pipe 4 connected to the input end. Air pipe 4 extends to the water surface. Then, air pipe 4 set on the cover 5 sucks in air and small dust particles from the cabinet 1 through fixed pipe 7, suction pipe 8, and suction hood 22. Air pipe 4 extends below the water surface. Then, air and small dust particles enter the water stored in treatment tank 3. Then, dust mixes with water and settles to the bottom of treatment tank 3. Air floats from the water surface and is sucked in by air pipe 4 connected to the input end of air pump 2, and then discharged through the output end of air pump 2.

[0042] When the suction speed needs to be adjusted according to the characteristics of intangible cultural heritage products, facing the tall cabinet 1, the staff can climb to the top of the top block 19 using the ladder 25. Then, they first rotate the control plate 13, which will cause the control hole 14 to rotate. When the control hole 14 rotates to a position concentric with the control rod 16, they push the control sleeve 15. The control sleeve 15 will cause the control rod 16 to slide into the control hole 14, and the control sleeve 15 and the control plate 13 will work together to compress the control spring 31. Then, the adapter rod 18 loses its limit. Then, rotating the control sleeve 15 will cause multiple slidingly set on the side wall to move. The adapter rod 18 moves, and then the inner wall of the adapter groove 17 on the outside of the fixed tube 7 presses against the inner end of the adapter rod 18. Due to the rounded corner design at the edge of the inner wall of the adapter groove 17 and the end of the adapter rod 18, the inner end of the adapter rod 18 slides out of the adapter groove 17, and the other end of the adapter rod 18 will drive the adapter spring 30 to stretch. At the same time, the control sleeve 6 will drive the linkage plate 9 to move through the movable shaft 12. Then, multiple linkage plates 9 will synchronously drive the linkage hole 27 to rotate. Since the diameter of the linkage hole 27 is larger than the diameter of the filter hole on the filter plate 24, the linkage hole 27 will not be blocked, and the other side of the linkage plate 9 will drive the linkage... Shaft 11 slides along linkage groove 10, causing multiple linkage plates 9 to simultaneously open linkage groove 10 outwards. This changes the cross-sectional area of ​​the opening inside control sleeve 6, resulting in a change in the flow area and thus a change in the volume of gas passing through, thereby altering the pumping speed. After proper adjustment, rotation of control sleeve 6 is stopped, and adapter spring 30 causes adapter rod 18 to slide back into the corresponding adapter groove 17. Then, control sleeve 15 is released, and control spring 31 pushes control sleeve 15 to slide back. Control sleeve 15 then causes control rod 16 to slide back. When control spring 31 is fully reset, control rod 16... The control rod is no longer inserted into the control hole 14. Then, the control plate 13 is rotated again, causing the control plate 13 to rotate the control hole 14 to a position that does not correspond to the control rod 16. Through the support of the control sleeve 15 by the control rod 16 and the control plate 13, and the preload applied by the control spring 31, the control sleeve 15 cannot easily slide. Then, the inner wall of the control sleeve 15 limits the outer end of the control rod 16, making the control rod 16 unable to move. Then, the control rod 16 and the control groove lock the control sleeve 6, making the control sleeve 6 unable to rotate, thereby ensuring the stability of the adjusted structure and ensuring the stable operation of the dust removal work.

For all the fixed connections mentioned above, welding is preferred.
