Description

Technical Field

[0001] This utility model relates to the field of calligraphy and painting protection technology, and in particular to a ground pole protection device for preventing calligraphy and painting from breaking. Background Technology

[0002] The base rod used for preserving calligraphy and paintings is a rod-shaped component used in the mounting of calligraphy and paintings to support the lower part of the artwork. When it is necessary to store the calligraphy and paintings, they are rolled up on the base rod for preservation.

[0003] Existing techniques typically use a single wooden rod with a small diameter. When paintings or calligraphy are rolled up and stored on this rod for extended periods, the paper fibers, being less elastic, stretch and deform when rolled, causing lateral tears and creases. Creases are a common problem with scroll paintings and calligraphy, reducing their aesthetic value and significantly impacting their lifespan. To address this, a common approach is to replace the rod with a larger diameter wooden one. However, this increases the overall weight, and during exhibitions, an excessively large rod can be space-consuming and inconvenient to handle. Furthermore, an overly heavy rod may crush or damage the artwork if handled improperly, thus diminishing its value.

[0004] The existing ground poles, which use wooden ground poles of fixed diameter, cannot simultaneously meet the operational needs of storing or displaying calligraphy and paintings, resulting in excessive space occupation and inconvenience in operation. Utility Model Content

[0005] This utility model provides a ground pole protection device for preventing the breakage of calligraphy and paintings, which solves the problems of excessive space occupation and inconvenient operation in the prior art. The technical solution is as follows:

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Figure 1 This is a schematic diagram of the overall structure provided in an embodiment of the present utility model; Figure 2 This is a schematic front view of the overall structure provided in an embodiment of the present utility model; Figure 3 This is an exploded view of the sub-shaft, sub-sleeve shaft, and sub-sleeve assembly provided in this embodiment of the utility model; Figure 4 This is a schematic diagram of the cross-section of the sub-sleeve provided in an embodiment of this utility model; Figure 5 This is a schematic diagram of the axial section of the sub-rod provided in an embodiment of this utility model. (See diagram below.) Figures 1 to 5 The illustrated protective device for preventing breakage of calligraphy and paintings includes: a rod shaft 1 and a sleeve shaft 2. The sleeve shaft 2 has an axially arranged mounting hole 21 at its circumferential edge. The rod shaft 1 passes through the mounting hole 21. The rod shaft 1 and the sleeve shaft 2 are detachably connected.

[0028] For example, in this embodiment of the present invention, the mounting hole 21 is formed on the circumferential edge of the sleeve shaft 2, creating an opening on the circumferential surface of the sleeve shaft 2. This allows the rod shaft 1 to be easily pressed into the sleeve shaft 2 through this opening, and also provides clearance for the installation of the scroll. The sleeve shaft 2 can be made of a flexible material, such as plastic foam, to reduce its weight. When installing the scroll, one end of the scroll is mounted on one side of the rod shaft 1, and then the sleeve shaft 2 is slipped over the rod shaft 1 from the other side. Since the mounting hole 21 is located on the circumferential edge of the sleeve shaft 2, the scroll will not interfere with the sleeve shaft 2. The scroll is then wrapped around the outside of the sleeve shaft 2 for storage. When the scroll needs to be transported or exhibited, the scroll wrapped around the sleeve shaft 2 can be unfolded, the sleeve shaft 2 removed, and the scroll wrapped around the rod shaft 1 again. The scroll will not crease when wrapped around the rod shaft 1 for a short time, and the smaller diameter of the rod shaft 1 results in a smaller volume of the wrapped scroll, facilitating its transport and exhibition. Compared to traditional techniques that use a fixed-diameter wooden structure for the ground pole, the ground pole structure in this embodiment is designed with a detachable connection between the pole shaft and the sleeve shaft. This ensures that the calligraphy and paintings will not be creased when stored and makes them easy to move during transportation or exhibition, thereby improving the ease of operation of this device.

[0029] This utility model provides a protective device for preventing the breakage of calligraphy and paintings by setting the base rod as a detachable connection between the rod shaft 1 and the sleeve shaft 2. This allows for easy adjustment of the base rod in different situations. When storing calligraphy and paintings, the sleeve shaft 2 is fitted onto the outside of the rod shaft 1 through the mounting hole 21, thereby increasing the diameter of the base rod. At this time, the scroll is wrapped around the outside of the sleeve shaft 2, so that the scroll will not crease when stored. When the scroll needs to be transported or exhibited, the scroll wrapped around the outside of the sleeve shaft 2 can be unfolded, the sleeve shaft 2 can be removed, and the scroll can be wrapped around the rod shaft 1 again. The scroll will not crease when wrapped around the rod shaft 1 for a short time, and the smaller diameter of the rod shaft 1 makes the volume of the wrapped scroll smaller, which is convenient for transportation and exhibition. This effectively solves the problem of excessive space occupation and inconvenience of operation in the prior art.

[0030] Optionally, the sleeve 2 includes a plurality of sub-sleeves 201, which are arranged along the length of the rod shaft 1.

[0031] For example, in this embodiment of the present invention, the sleeve shaft 2 is set to be composed of multiple sleeve shafts 201 spliced ​​together, so that the sleeve shaft 2 can be installed in sections, and different numbers of sleeve shafts 2 can be selected according to the actual width of the scroll being wound, thereby improving the ease of operation of the device.

[0032] Optionally, a sleeve 3 is fitted outside the shaft 1. The sleeve 3 is a cylindrical structure with a notch and is disposed in the mounting hole 21.

[0033] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, the notch in sleeve 3 is located on the circumferential surface to allow for clearance of the installed scroll. By providing sleeve 3, the rod shaft 1 engages with the sleeve shaft 2 via sleeve 3. Since the sleeve shaft 2 is made of materials such as plastic foam, it is typically fixed using adhesive. If adhesive were directly applied to the outside of the rod shaft 1 to engage with the sleeve shaft 2, it would easily cause adhesive residue to adhere to the outside of the rod shaft 1, making replacement difficult. By adding sleeve 3, adhesive can be applied to the outer wall of sleeve 3 to engage with the sleeve shaft 2. Sleeve 3 can also be made of materials such as plastic, facilitating replacement. The addition of sleeve 3 further improves the ease of operation of this device.

[0034] Optionally, the sleeve 3 includes a plurality of sub-sleeves 301, which are arranged along the length of the rod shaft 1.

[0035] For example, in this embodiment of the present invention, by setting the sleeve 3 in the form of multiple sub-sleeves 301, the sleeve 3 can be conveniently installed, and the sub-sleeves 301 and the sub-sleeve shaft 201 can be set to the same length. The number of sub-sleeve shafts 201 can be set accordingly to further improve the ease of operation of the device.

[0036] Optionally, one end of the sub-sleeve 301 is provided with a first limiting protrusion 302, and the other end is provided with a first limiting groove 303, wherein the first limiting protrusion 302 and the first limiting groove 303 are matched.

[0037] Exemplary, in embodiments of this utility model, such as Figure 4 As shown, the first limiting protrusion 302 of each sub-sleeve 301 is inserted into the first limiting groove 303 of another sub-sleeve 301, thereby connecting multiple sub-sleeves 301. Multiple first limiting protrusions 302 can be provided at the ends of the sub-sleeves 301 to match multiple first limiting grooves 303, thus preventing rotation between adjacent sub-sleeves 301. This structure makes the connection between multiple sub-sleeves 301 more stable, improving the structural stability of the device.

[0038] Optionally, the inner wall of the sleeve 301 is provided with anti-rotation ribs 41 arranged along the length direction, and the shaft 1 is provided with anti-rotation grooves 42 that match the anti-rotation ribs 41.

[0039] Exemplary, in embodiments of this utility model, such as Figure 3As shown, the anti-rotation rib 41 is arranged along the length of the sub-sleeve 301. When the sub-sleeve 301 is fitted with the rod shaft 1, the anti-rotation rib 41 is aligned with the anti-rotation groove 42 before the rod shaft 1 is pushed into the inner ring of the sub-sleeve 301. By setting this structure, relative rotation between the sub-sleeve 301 and the rod shaft 1 in the circumferential direction can be prevented, thereby making the fit between the sub-sleeve 301 and the rod shaft 1 more stable, thus further improving the structural stability of the device.

[0040] Optionally, an anti-slip ring 51 is provided inside the sleeve 301, and an anti-slip groove 52 matching the anti-slip ring 51 is provided on the shaft 1.

[0041] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, the anti-slip ring 51 also has a notch, arranged circumferentially along the sub-sleeve 310. When the sub-sleeve 301 is fitted with the rod shaft 1, the anti-slip ring 51 is aligned with the anti-slip groove 52 before the rod shaft 1 is pushed into the inner ring of the sub-sleeve 301. By setting this structure, relative displacement along the length direction between the sub-sleeve 301 and the rod shaft 1 can be prevented, thereby making the fit between the sub-sleeve 301 and the rod shaft 1 more stable, thus further improving the structural stability of the device.

[0042] Optionally, a roller 6 is provided at the notch of the sleeve 3, and the roller 6 is slidably connected to the circumferential surface of the rod shaft 1.

[0043] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, when both the anti-rotation rib 41 and the anti-slip ring 51 are installed inside the sub-sleeve 301, the rod shaft 1 cannot be inserted into the sub-sleeve 301 along its length. Instead, the rod shaft 1 can only be pushed into the sub-sleeve 301 through the notch. The sleeve 3 can be made of materials such as plastic, which can deform to a certain extent, allowing the rod shaft 1 to be pushed into the sub-sleeve 301. By installing the roller 6 at the notch of the sleeve 3, the friction force of pushing the rod shaft 1 into the sub-sleeve 301 can be reduced, thereby further improving the ease of operation of this device.

[0044] Optionally, the rod shaft 1 includes a plurality of sub-rod shafts 101. One end of each sub-rod shaft 101 is provided with a second limiting protrusion 102 and the other end is provided with a second limiting groove 103. The second limiting protrusion 102 and the second limiting groove 103 are matched.

[0045] Exemplary, in embodiments of this utility model, such as Figure 5As shown, by inserting the second limiting protrusion 102 of each sub-shaft 101 into the second limiting groove 103 of the adjacent sub-shaft 101, multiple sub-shafts 101 are spliced ​​together to form a shaft. By setting the shaft 1 in the form of splicing multiple sub-shafts 101, different numbers of sub-shafts 101 can be selected for splicing according to actual usage requirements, thereby changing the total length of the shaft 1 and improving the compatibility of the device. On the other hand, when some sub-shafts 101 are damaged, only the damaged sub-shafts 101 can be disassembled, and the remaining intact sub-shafts 101 can continue to be used, thereby improving the service life of the device.

[0046] Optionally, side guard plates 7 are provided at both ends of the rod shaft 1.

[0047] Exemplary, in embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the side guard plate 7 is a circular plate structure with a diameter larger than that of the rod shaft 1. When the scroll needs to be transported or exhibited, it is directly wrapped around the outside of the rod shaft 1. To prevent the sides of the scroll from being damaged by external physical impacts, the side guard plate 7 is provided to protect the sides of the scroll, thereby improving the safety of the device.
