Description

Technical Field

[0001] This utility model relates to the field of cultural relic restoration technology, specifically to a clamp for the protection and restoration of pottery cultural relics. Background Technology

[0002] "Ceramics" is generally divided into two main categories: pottery and porcelain. "Ceramics" is actually a collective term for both types of vessels, with porcelain evolving from pottery. Pottery and porcelain differ significantly in raw materials, firing temperatures, and glazing techniques: Pottery consists of clay and porcelain stone products whose bodies are not densely sintered; the portion fired at higher temperatures and with better sintering is called "hard pottery"; the glazed type is called "glazed pottery"; and clay or porcelain stone products fired at high temperatures, with a denser body and excellent glaze quality are called "porcelain." The development of traditional ceramics spanned a considerable historical period, resulting in a wide variety of types and unique techniques. With the development of archaeology and the continuous enrichment of archaeological findings, more and more artifacts are awaiting excavation. After excavation, these artifacts require restoration, including cleaning, bonding, and plastering of broken pieces. The primary purpose is to facilitate typological research by archaeologists. In the context of the new era, society has placed higher demands on cultural relics work. Cultural relics restorers should do their best to improve the effectiveness of cultural relics restoration, explore the value and connotation of cultural relics, and truly bring cultural relics to life, thereby promoting the effective use of cultural relics and ensuring that the achievements of cultural relics protection benefit more people.

[0003] Because pottery artifacts are relatively brittle, excessive clamping force can easily cause them to crack or break. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a clamp for the protection and restoration of pottery artifacts, which uses an electromagnet to generate pressure in the thickness direction of the bottom wall of the pottery artifact to fix it in place.

[0005] This utility model is achieved through the following technical solution: a clamp for the protection and restoration of pottery cultural relics, including a platform, an inserter and an adsorption component; The platform is equipped with a first electromagnet, the implanter is located on the platform, the implanter includes a frame, a crossbeam is fixedly connected to the top of the frame, a telescopic rod is fixedly connected to the bottom of the crossbeam, a second electromagnet is fixedly connected to the bottom of the telescopic rod, an air pump is provided on the crossbeam, an air injection port is provided at the bottom of the telescopic rod, and the air injection port is connected to the air pump. The adsorption component includes an iron sheet, with an air bladder fixedly connected to the bottom of the iron sheet. The air inlet of the air bladder extends to the top of the iron sheet, and the air injection port engages with the air inlet. The airbag has a pressure trigger switch at the bottom, which is electrically connected to a metal conductive plate. The telescopic rod has a metal conductive base at the bottom, and the air pump is electrically connected to the metal conductive base.

[0006] Furthermore, a rotating platform is rotatably connected to the platform body, the first electromagnet is located on the rotating platform, and the platform body is provided with a first driving component that drives the rotating platform to rotate.

[0007] Furthermore, the implanter is rotatably connected to the platform, and a second driving component for driving the implanter to rotate is provided inside the platform.

[0008] Furthermore, a soft sleeve is provided at the bottom of the airbag, and the soft sleeve has a through hole, with the pressure trigger switch located inside the through hole.

[0009] Furthermore, several guard rods are rotatably connected to the platform, and the guard rods are distributed circumferentially around the rotating platform. Each guard rod is fixedly connected with an elastic net.

[0010] Furthermore, a projection light is installed at the bottom of the telescopic pole.

[0011] Furthermore, a level is fixedly connected to one side of the rotating platform.

[0012] The technical solution of this utility model has at least the following beneficial effects: Pottery artifacts are mostly in the form of plates, bowls, or bottles. When fixing pottery artifacts, the adsorption component is first attached to the bottom of the telescopic rod by the second electromagnet. At this time, the air inlet is connected to the air inlet of the air bag, and the metal conductive plate is in contact with the metal conductive base. The telescopic rod of the inserter is then moved to directly above the pottery artifact. The telescopic rod is then activated to lower the adsorption component close to the bottom wall of the pottery artifact.

[0013] When the suction device is positioned a short distance above the bottom wall of the pottery artifact, the air pump injects gas into the air bladder, causing it to inflate. The inflated air bladder thickens the suction device, causing its bottom to press against the bottom wall of the pottery artifact. When the first electromagnet on the platform is energized, it generates a magnetic force on the iron plate, attracting it and causing the suction device to exert downward pressure on the bottom wall of the pottery artifact, pressing the pottery onto the platform and securing it in place.

[0014] Because the force of the adsorption component is in the thickness direction of the bottom wall of the pottery artifact, the pressure generated will directly act on the pottery material of the bottom wall. Unlike the existing technology that applies a lateral clamping force, the torque generated by the adsorption component is smaller and less likely to cause the cracks of the pottery artifact to expand due to the force. At the same time, the overall volume occupied is smaller and there is less volume interference during the restoration process. The airbag can expand to fill the space between the iron sheet and the bottom wall of the pottery artifact, adapting to pottery artifacts with different bottom wall thicknesses, and keeping the distance between the iron sheet and the first electromagnet the same each time it is used, thereby controlling the magnetic attraction force and avoiding the bottom wall of the pottery artifact being damaged due to excessive magnetic attraction force or the pottery artifact being loosened due to insufficient magnetic attraction force.

[0015] The pressure-triggered switch controls the expansion of the airbag. When the airbag expands to the point where it touches the bottom wall of the pottery artifact, the pressure-triggered switch is triggered and disconnected due to sufficient pressure. When the suction device is attached to the telescopic rod, the pressure-triggered switch forms a series circuit with the air pump through the metal conductive plate and the metal conductive socket. When the pressure-triggered switch disconnects, it cuts off the power to the air pump, thereby stopping the airbag from expanding further. The expansion size of the airbag is controlled to precisely fill the gap between the iron plate and the bottom wall of the pottery artifact. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The following detailed description illustrates the specific implementation method: Example 1 As attached Figures 1-7 As shown, a clamp for the protection and restoration of pottery artifacts includes a platform 1, an inserter 2, and an adsorption component 3.

[0022] A rotating platform 5 is rotatably connected to the platform 1. A first electromagnet 4 is located on the rotating platform 5. A first driving component 6 that drives the rotating platform 5 to rotate is provided inside the platform 1. The first electromagnet 4 is provided on the rotating platform 5. The inserter 2 is rotatably connected to the platform 1. A second driving component 7 that drives the inserter 2 to rotate is provided inside the platform 1. Both the first driving component 6 and the second driving component 7 are motors. The inserter 2 includes a frame 201. A crossbeam 202 is bolted to the top of the frame 201. A telescopic rod 203 is bolted to the bottom of the crossbeam 202. The telescopic rod 203 is a cylinder. A second electromagnet 204 is bolted to the bottom of the telescopic rod 203. An air pump 205 is provided on the crossbeam 202. An air injection port 206 is provided at the bottom of the telescopic rod 203. The air injection port 206 is connected to the air pump 205.

[0023] The adsorption component 3 includes an iron sheet 301, to the bottom of which an airbag 302 is bonded and fixed. The air inlet 303 of the airbag 302 extends to the top of the iron sheet 301, and the air injection port 206 engages with the air inlet 303. A soft sleeve 306 is provided at the bottom of the airbag 302, and the soft sleeve 306 has a through hole. A pressure trigger switch 304 is located in the through hole.

[0024] The airbag 302 has a pressure trigger switch 304 at the bottom. The pressure trigger switch 304 is model QPM11-NC. The pressure trigger switch 304 is electrically connected to a metal conductive piece 305. The telescopic rod 203 has a metal conductive female seat 207 at the bottom. The air pump 205 is electrically connected to the metal conductive female seat 207.

[0025] Pottery artifacts are mostly in the form of plates, bowls, or bottles. When securing pottery artifacts, the suction device 3 is first attached to the bottom of the telescopic rod 203 via the second electromagnet 204. The air inlet 206 is connected to the air inlet 303 of the airbag 302, and the metal conductive pad 305 is in contact with the metal conductive base 207. The telescopic rod 203 of the inserter 2 is then moved directly above the pottery artifact, and the telescopic rod 203 is activated, lowering the suction device 3 close to the bottom wall of the pottery artifact. Taking a bottle-shaped pottery artifact as an example, the telescopic rod 203 of the inserter 2 will directly penetrate the bottle, ensuring that it does not contact the bottle wall during the insertion process.

[0026] When the adsorbent 3 is located not far above the bottom wall of the pottery artifact, the air pump 205 injects gas into the air bag 302, causing the air bag 302 to inflate. The inflated air bag 302 thickens the adsorbent 3, causing its bottom to press against the bottom wall of the pottery artifact. De-energizing the second electromagnet 204 allows the adsorbent 3 to detach from the pottery artifact. When the first electromagnet 4 on the platform 1 is energized, it generates a magnetic attraction to the iron plate 301, causing the adsorbent 3 to exert downward pressure on the bottom wall of the pottery artifact, pressing the artifact onto the platform 1 and securing it.

[0027] Since the force of the adsorption element 3 is in the thickness direction of the bottom wall of the pottery artifact, the pressure generated will directly act on the pottery material of the bottom wall. Unlike the existing technology that applies a lateral clamping force, the torque generated by the adsorption element 3 is smaller and less likely to cause the cracks of the pottery artifact to expand due to the force. At the same time, it occupies a smaller volume and has less volume interference during the restoration process. The inflatable airbag 302 fills the space between the iron plate 301 and the bottom wall of the pottery artifact, adapting to pottery artifacts with different bottom wall thicknesses. It also maintains the same distance between the iron plate 301 and the first electromagnet 4 each time it is used, thereby controlling the magnetic attraction force and preventing excessive magnetic force from damaging the bottom wall of the pottery artifact or insufficient magnetic force from loosening it. The soft sleeve 306 provides cushioning, reducing the rigid effect of the airbag 302 on the bottom of the pottery artifact.

[0028] The pressure-triggered switch 304 controls the expansion degree of the airbag 302. When the airbag 302 expands to a point where it touches the bottom wall of the pottery artifact, the pressure-triggered switch 304 will be triggered to disconnect due to sufficient pressure. When the adsorption component 3 is adsorbed onto the telescopic rod 203, the pressure-triggered switch 304 forms a series circuit with the air pump 205 through the metal conductive sheet 305 and the metal conductive socket 207. When the pressure-triggered switch 304 disconnects, it will de-energize the air pump 205, thereby stopping the airbag 302 from expanding further. The expansion size of the airbag 302 is controlled to just fill the distance from the iron sheet 301 to the bottom wall of the pottery artifact.

[0029] After securing the pottery artifact, the user can rotate the rotating platform 5 to adjust the orientation of the artifact for easier subsequent restoration work. The inserter 2 is also rotatably connected to the platform 1. After inserting the suction element 3, the telescopic rod 203 of the inserter 2 can be rotated to the other side to reduce its spatial volume from interfering with subsequent restoration work. Once the restoration is complete, the user can rotate the inserter 2 to align the telescopic rod 203 with the suction element 3, and then use the second electromagnet 204 to attract the suction element 3, removing it from the pottery artifact.

[0030] Example 2 The difference from the above embodiment is that a number of guard rods 8 are rotatably connected to the platform 1. The guard rods 8 are distributed circumferentially around the rotating platform 5, and each guard rod 8 is fixedly connected with an elastic net 9.

[0031] After placing the pottery artifact on the platform 1, the guard rod 8 can be rotated to support it, thereby constructing a protective net to ensure that if the pottery artifact falls before being secured by the pottery artifact, it can be protected by the elastic net 9.

[0032] Example 3 The difference from the above embodiment is that a projection lamp 208 is provided at the bottom of the telescopic rod 203.

[0033] The projection lamp 208 is used to project a light spot under the telescopic rod 203, so that the user can determine the position of the telescopic rod 203 and accurately probe into the pottery artifact.

[0034] Example 4 The difference from the above embodiment is that a level 10 is bolted to one side of the rotating table 5.

[0035] The level 10 can check the level of the rotating table 5, making it easy for the user to determine the level surface, so as to make accurate measurements and operations during the repair process.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
