Description

Technical Field

[0001] This utility model relates to the field of cultural relic protection and exhibition technology, specifically a modular display stand. Background Technology

[0002] The patterns on Majiayao painted pottery are mainly geometric, with the most representative being spiral patterns, water ripple patterns, concentric circle patterns, and sawtooth patterns. These patterns originate from the ancient people's observation of natural phenomena, embodying their reverence for and dependence on water, and also reflecting the symmetrical aesthetics of primitive art. Currently, to better showcase the aesthetic beauty of the painted pottery, modular display stands are often used. Their structure is easy to disassemble and move, allowing for assembly and arrangement during museum exhibition layout adjustments or touring exhibitions, improving exhibition efficiency. They can easily create a display atmosphere, and when combined with lighting elements, can better highlight the cultural connotations and artistic value of Majiayao painted pottery, enhancing the audience's viewing experience. The existing modular display stand mainly consists of a base, a drive system, and multiple layers of discs for displaying painted pottery patterns. Each layer of discs is fixed to the connecting shaft of the drive system via riveting or multiple bolts for assembly. However, there are some issues with compatibility: the riveting process requires specialized tools for installation and disassembly, which is time-consuming and cannot be adjusted on-site; bolted connections require aligning bolt holes one by one, inserting and tightening multiple bolts, which is cumbersome, slows down the exhibition setup, and may damage the ceramics due to bumps during installation; therefore, we propose a modular display stand to solve the problems encountered by existing technologies. Utility Model Content

[0003] The purpose of this utility model is to provide a modular display stand to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular display stand, including a base, with a connecting shaft and three discs rotatably mounted on the upper end of the base. A limiting component is provided between the periphery of the connecting shaft and the axis of each disc. Multiple annular grooves are formed on the periphery of the connecting shaft. Each limiting component includes an inner cylinder sleeved around the connecting shaft, and an outer cylinder movably mounted around the inner cylinder. Multiple locking blocks are elastically arranged within the inner cylinder wall. The outer cylinder moves downward, driving each locking block to abut against the inner wall of the annular groove for assembling the discs.

[0005] Preferably, a motor is fixed to the bottom wall of the base, and the output end of the motor is fixed to the lower end of the connecting shaft through a flange to drive the connecting shaft to rotate.

[0006] Preferably, the upper end of the base is fitted with a glass cover, and the upper end of the disc has a groove and a recess for placing ceramic jars.

[0007] Preferably, a lamp body is disposed in the groove, and a pattern is disposed at the upper end of the groove, wherein the substrate of the pattern is made of acrylic material.

[0008] Preferably, the lower end of the inner cylinder is fixed to the axis of the disc, the outer surface of the inner cylinder is provided with an external thread, the inner wall of the outer cylinder is provided with an internal thread for engaging with the external thread, the inner wall of the inner cylinder is provided with a ramp, and the inner side of the ramp abuts against the outer end of the locking block to drive each locking block to move simultaneously toward the axis of the inner cylinder.

[0009] Preferably, the plurality of the locking blocks are symmetrically arranged about the axis of the inner cylinder, and a spring is welded between the outer end of the locking block and the outer surface of the inner cylinder.

[0010] Preferably, the inner end of the card block is provided with an arc surface, and the inner wall of the arc surface is integrally provided with a protrusion for abutting against the inner wall of the annular groove, and the inner wall of the annular groove is coated with a rubber coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The display stand is assembled by using elastic clips and annular grooves. During assembly, the disc can be quickly installed and disassembled simply by rotating the outer cylinder. No professional tools or bolt holes need to be aligned one by one. This can shorten the setup time, avoid damage to the painted pottery during installation, and facilitate museums to adjust the layout or conduct touring exhibitions. 2. The lamp body, in conjunction with the illumination of acrylic patterns, can highlight the symmetrical aesthetics and cultural connotations of geometric patterns such as swirling patterns and water ripples on painted pottery, enhancing the viewing experience. Early, middle, and late Majiayao painted pottery are placed in three circular pottery jar placement slots in chronological order, with patterns from the corresponding period embedded in the corresponding slots. By rotating the discs and illuminating them in layers with the lamp body, viewers can intuitively see the evolution of the patterns from simple concentric circle patterns in the early period to complex swirling patterns in the middle period, and then to a combination of sawtooth patterns and water ripple patterns in the late period. This clearly presents the temporal and spatial context and avoids the monotony of traditional exhibition methods. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 6 As shown, a modular display stand includes a base 1. A connecting shaft 2 and three discs 3 are rotatably mounted on the upper end of the base 1. A limiting member 4 is provided between the periphery of the connecting shaft 2 and the axis of each disc 3. Multiple annular grooves 10 are provided on the periphery of the connecting shaft 2. The limiting member 4 includes an inner cylinder 41 sleeved on the periphery of the connecting shaft 2. An outer cylinder 43 is movably mounted on the periphery of the inner cylinder 41. Multiple locking blocks 42 are elastically mounted inside the inner cylinder 41. The outer cylinder 43 moves down to drive each locking block 42 to abut against the inner wall of the annular groove 10 for assembling the discs 3. By defining the assembly relationships of the core components of the display stand, such as the base 1, connecting shaft 2, disc 3, and limiting component 4, the layout of the three-layer disc 3 is clarified, reserving space for the layered and categorized display of Majiayao painted pottery, such as arranging them according to the stages of pattern evolution. The combination structure of the inner cylinder 41 and outer cylinder 43 of the limiting component 4 with the elastic locking block 42, as well as the cooperation method with the annular groove 10 of the connecting shaft 2, is clarified. Rapid assembly is achieved by the outer cylinder 43 moving down to drive the locking block 42 to abut, solving the problem of insufficient compatibility caused by the cumbersome and inefficient operation of traditional riveting or bolting connections.

[0021] The design of the flexible locking block 42 and the annular groove 10 takes into account both the firmness of the connection and the flexibility of disassembly. It not only ensures the stability of the disc 3 during operation and prevents the painted pottery from tipping over, but also makes it easier for museums to adjust the exhibition layout or touring exhibitions, thus improving the overall exhibition adaptability of the device.

[0022] Specifically, Figure 5 In the middle, a motor 5 is fixed to the bottom wall of the base 1, and the output end of the motor 5 is fixed to the lower end of the connecting shaft 2 through a flange to drive the connecting shaft 2 to rotate; By clearly defining the fixed position of motor 5 on the bottom wall of base 1 and the flange connection method with connecting shaft 2, the stable output power of motor 5 is ensured, driving connecting shaft 2 to rotate disc 3, providing reliable power for the dynamic display of painted pottery and the intuitive presentation of the pattern evolution sequence. It should be noted that the suitable speed of motor 5 is 0.5–1 revolutions per minute (rpm), which can balance the safety of painted pottery and the viewing experience. In this speed range, firstly, the extremely low speed can greatly reduce the impact of centrifugal force on painted pottery. Combined with the limiting position of pottery jar placement slot 6 on disc 3, it can prevent painted pottery from sliding or falling due to centrifugal force, while reducing vibration transmission; secondly, the slow rotation allows the audience to clearly observe the geometric patterns such as vortex patterns and water ripple patterns around the painted pottery. It is neither limited by the viewing angle due to stillness nor visually blurred due to excessive speed, which is suitable for the detailed viewing needs of Majiayao painted pottery patterns.

[0023] Specifically, Figure 1 and Figure 6 In the middle, a glass cover is fitted on the upper end of the base 1, and a pottery jar placement slot 6 and a groove 7 are opened in the upper end of the disc 3; By installing the glass cover on the upper part of the base 1, and by opening the pottery jar placement slots 6 and grooves 7 on the disc 3, the glass cover can effectively prevent dust and contact, and protect the safety of Majiayao painted pottery; the pottery jar placement slots 6 and grooves 7 can realize the orderly placement of painted pottery and pattern 9, avoid the chaos of the exhibition, and at the same time reserve reasonable space for the installation of lamp body 8 and lighting.

[0024] Specifically, Figure 6 In the middle, a lamp body 8 is set in the groove 7, and a pattern 9 is set at the upper end of the groove 7. The substrate of the pattern 9 is made of acrylic material. By clearly defining the placement of the lamp body 8 within the groove 7, the installation method of the pattern 9, and the material of the acrylic substrate, the good light transmittance of the acrylic material, combined with the illumination of the lamp body 8, can enhance the visual clarity of the pattern 9, highlighting the symmetrical aesthetics of geometric patterns such as painted pottery vortex patterns and water ripple patterns, allowing the audience to more clearly perceive the cultural connotations and enhance the viewing experience.

[0025] Specifically, Figure 2 In the middle, the lower end of the inner cylinder 41 is fixed to the axis of the disk 3. The outer surface of the inner cylinder 41 is provided with external threads, and the inner wall of the outer cylinder 43 is provided with internal threads for engaging with the external threads. The inner wall of the inner cylinder 41 is provided with a ramp 47, and the inner side of the ramp 47 abuts against the outer end of the locking block 42 to drive each locking block 42 to move simultaneously toward the axis of the inner cylinder 41. By describing the fixed relationship between the inner cylinder 41 and the disc 3, the threaded engagement between the inner cylinder 41 and the outer cylinder 43, and the cooperation between the inner wall ramp 47 of the inner cylinder 41 and the locking block 42, the threaded connection ensures that the outer cylinder 43 moves smoothly downwards, and the ramp 47 structure can drive the two locking blocks 42 to move synchronously towards the axis, providing stable structural support for the rapid assembly of the disc 3 and the connecting shaft 2, and solving the problems of cumbersome and inefficient operation of traditional riveting / bolt connection.

[0026] Specifically, Figure 2 and Figure 4 In the middle, multiple locking blocks 42 are symmetrically arranged on the left and right with the axis of the inner cylinder 41 as the center, and springs 44 are welded between the outer end of the locking block 42 and the outer surface of the inner cylinder 41. The symmetrical design of the locking block 42 ensures that the force on the locking block 42 is balanced, and the spring 44 provides the locking block 42 with elastic reset capability. This ensures that the locking block 42 and the annular groove 10 are tightly fitted and firmly fixed, while also facilitating subsequent disassembly and adjustment, improving the flexibility of the display stand assembly and adapting to the needs of museum layout adjustments and traveling exhibitions.

[0027] Specifically, Figure 4 In the middle, the inner end of the card block 42 is provided with an arc surface 46, and the inner wall of the arc surface 46 is integrally provided with a protrusion 45 for abutting against the inner wall of the annular groove 10, and the inner wall of the annular groove 10 is coated with a rubber coating. The rubber coating can buffer vibration and increase friction, preventing loose connections from causing the disc 3 to tilt or the painted pottery to fall. It also reduces wear and tear on components during assembly and disassembly, ensuring the safety of cultural relics during exhibition.

[0028] Working principle: Place the base 1 in a stable position, and assemble the three discs 3 to the corresponding positions of the connecting shaft 2 through the limiting parts 4. Sleeve the inner cylinder 41 around the connecting shaft 2 and fix the lower end of the inner cylinder 41 to the axis of the disc 3. Rotate the outer cylinder 43 to move it down along the external thread on the outer surface of the inner cylinder 41. The downward movement of the outer cylinder 43 drives the locking block 42 to move along the slope 47 of the inner wall of the inner cylinder 41 towards the axis of the inner cylinder 41. The protrusion 45 on the inner end arc surface 46 of the locking block 42 is inserted into the annular groove 10 around the connecting shaft 2 and abuts against the rubber coating in the groove, thus completing the assembly. Next, place Majiayao painted pottery into the pottery jar placement slot 6 of the disc 3, embed acrylic pattern 9 into the groove 7, and place the glass cover on the upper end of the base 1. Then, the motor 5 drives the connecting shaft 2 to rotate the disc 3, and the brightness of the lamp body 8 is adjusted to complete the display. When the lamp body 8 illuminates the acrylic pattern 9, it can highlight the symmetrical aesthetics and cultural connotations of geometric patterns such as the painted pottery vortex pattern and water ripple pattern, enhancing the viewing experience. The early, middle and late Majiayao painted pottery are placed in the pottery jar placement slots 6 of the three discs 3 in chronological order, and the corresponding pattern 9 is embedded in the grooves 7. The motor 5 drives the connecting shaft 2 to rotate the disc 3 at a uniform speed, and the lamp body 8 illuminates it in layers, allowing the audience to intuitively see the evolution of the pattern from the simple concentric circle pattern in the early period to the complex vortex pattern in the middle period, and then to the combination of sawtooth pattern and water ripple pattern in the late period, clearly presenting the time and space context.
