Description

Technical Field

[0001] The present invention belongs to the technical field of protective containers, and particularly relates to an anti-oxidation sealing device for cultural relic protection. Background Art

[0002] During archaeological excavations, organic cultural relics such as books, paintings, textiles, grains, lacquerware, and leather, as well as inorganic cultural relics such as painted pottery, are often unearthed. When these cultural relics are first unearthed and directly exposed to the external environment, they are likely to be damaged by contact with moisture, oxygen, molds, etc. in the air. Therefore, after the cultural relics are unearthed, archaeologists need to promptly transfer the unearthed cultural relics to a cultural relic protection laboratory for storage and research. When the unearthed cultural relics cannot be loaded and transported in a timely manner due to weather, distance, etc., they need to be temporarily stored on-site.

[0003] When cultural relics are transferred or temporarily stored, they need to be placed in corresponding containers. For example, "GB / T 23862-2024 Specifications for Packaging and Transportation of Cultural Relics" records that boxes made of corrugated cardboard, framed wooden boxes, fiberboard, etc. can be used as temporary storage containers for cultural relics. A moisture-proof and waterproof film is pasted on the inner wall of the container, and buffer materials such as cotton cloth and foam plastic are filled to prevent bumping. Although the above-mentioned corrugated cardboard, framed wooden boxes, etc. can to a certain extent isolate the contact between cultural relics and the external environment, they cannot completely isolate. If the archaeological site is relatively remote or transportation is impossible due to weather factors, and the cultural relics need to be stored in the container for a long time, the cultural relics may still be damaged by the external environment, causing irreparable losses. Summary of the Invention

Detailed implementation manners

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Please refer to Figures 1 to 8 together, and the anti - oxidation sealing device for cultural relic protection provided by the present invention will be described below. Among them Figures 1 to 4 are the relevant views of the first embodiment of the anti - oxidation sealing device for cultural relic protection, Figures 5 to 8 are the relevant views of the second embodiment of the anti - oxidation sealing device for cultural relic protection. The main difference between the first embodiment and the second embodiment lies in the shape and structure of the protective cover 40.

[0020] Specifically, please refer to Figures 1 to 4, the anti-oxidation sealing device for cultural relic protection provided by the present invention includes a protective box body 10, a protective backing plate 20, a sealing element 30, a protective cover 40 and a connecting unit 50. The protective box body 10 has a protective cavity, the inner wall of the protective cavity is covered with a flexible protective layer, a placing and taking opening is formed through the wall thickness of the protective box body 10 at the top of the protective cavity, and a sealing groove 11 is formed around the placing and taking opening at the top of the protective box body 10; the protective backing plate 20 is accommodated in the protective cavity and is located at the bottom of the protective cavity; the sealing element 30 is annular and is accommodated in the sealing groove 11; the protective cover 40 is covered on the placing and taking opening and abuts against the sealing element 30, and an air nozzle 41 is provided on the protective cover 40, the air nozzle 41 communicates with the protective cavity, and the air nozzle 41 is used for connecting with an inert gas source or a vacuum pump; the connecting unit 50 is connected between the protective box body 10 and the sealing element 30, and the connecting unit 50 is used for applying a pre-tightening force to the protective cover 40 to press the protective cover 40 against the sealing element 30.

[0021] Compared with the prior art, the beneficial effects of the anti-oxidation sealing device for cultural relic protection provided by the present invention are: The anti-oxidation sealing device for cultural relic protection provided by the present invention includes a protective box body 10, a protective backing plate 20, a sealing element 30, a protective cover 40 and a connecting unit 50. The protective box body 10 has a protective cavity, and a flexible protective layer is provided on the inner wall of the protective cavity. The protective backing plate 20 is arranged in the protective cavity and can protect the bottom and the surrounding of the cultural relic to prevent it from being knocked and scratched. The protective cover 40 and the protective box body 10 are connected into an integral body through the connecting unit 50, and a sealing element 30 is provided on the contact surface between the protective cover 40 and the protective box body 10. The sealing element 30 deforms under the extrusion force and can seal the gap on the contact surface, so that the cultural relic is in a completely enclosed environment. An air nozzle 41 is provided on the protective cover 40. Through the air nozzle 41, the air in the protective cavity can be pumped out and an inert gas such as nitrogen can be filled. The inert gas can prevent the damage of cultural relics such as books and paintings, painted pottery, ironware, etc. caused by environmental factors such as oxygen, humidity, polluting gases, harmful organisms and mildew, and plays an anti-oxidation protection role.

[0022] The protective box body 10 and the protective cover 40 are used to enclose a sealed protection space, and the cultural relic is placed in the sealed protection space. The protective box body 10 and the protective cover 40 can be made of materials such as metal, high-strength plastic, carbon fiber, etc., and have high structural strength and are not easily damaged. The inner part of the protective cavity is covered with a flexible protective layer, and the flexible protective layer can be a flocked fabric, a cotton cloth layer, a rubber layer, etc. It can be covered on the inner wall of the protective cavity by means of bonding, riveting connection, etc.

[0023] The protective box body 10 and the protective cover 40 can be designed in various specifications according to the size, and the appropriate-sized protective box body 10 and protective cover 40 can be selected according to the volume of the cultural relic.

[0024] In use, first place the protective backing plate 20 stably at the bottom of the protective cavity, and then place the cultural relics to be transferred or stored above the protective backing plate 20. When the gap between the four sides of the cultural relics and the inner wall of the protective cavity is large, buffer materials such as cotton cloth and foam plastic can be filled into it to prevent the cultural relics from shaking significantly during transportation. After the cultural relics are fixed, place the sealing element 30 into the sealing groove 11, cover the protective cover 40, and install the connecting unit 50 so that there is a certain pre-tightening force between the protective cover 40 and the protective box body 10. The sealing element 30 is deformed under pressure to seal the joint surface between the protective cover 40 and the protective box body 10, ensuring airtightness. After the connecting unit 50 is installed, first connect the air nozzle 41 to the vacuum pump through a gas hose, and the vacuum pump pumps out the air in the protective cavity. Then connect the air nozzle 41 to an inert gas source (such as nitrogen) to fill the protective box body 10 with inert gas, playing an anti-oxidation role. The air pressure of the inert gas in the protective box body 10 is greater than the external atmospheric pressure, and it is not easy to leak.

[0025] The connecting unit 50 is used to connect the protective cover 40 and the protective box body 10 into one body. The connecting unit 50 can be common connecting parts such as bolts. In addition, an anti-theft lock can be set between the protective cover 40 and the protective box body 10 to prevent the cultural relics from being stolen.

[0026] Please refer to Figures 2 to 4 , the anti-oxidation sealing device for cultural relic protection further includes a limiting unit 60. The limiting unit 60 is accommodated in the protective cavity and is located above the protective backing plate 20. The limiting unit 60 has a limiting space for accommodating cultural relics and can isolate and limit the cultural relics.

[0027] There are two functions of setting the limiting unit 60. One is that when the gap between the volume of the cultural relics and the protective cavity is large, in order to prevent the cultural relics from being damaged by bumping due to shaking, an additional limiting unit 60 is added above the protective backing plate 20 to assist in supporting and limiting the cultural relics. The other is that the protective cavity can be divided into multiple spaces by the limiting unit 60, and different cultural relics can be stored in each of the multiple spaces respectively, improving the space utilization rate.

[0028] The limiting unit 60 can be made of corrugated board, plastic, etc. When used to store fragile items such as ceramics, a buffer material layer should be provided on the surface of the limiting unit 60 or in the space between it and the cultural relics.

[0029] Please refer to Figures 2 to 6, sliding grooves 16 are respectively formed on the inner walls of the opposite sides of the protection cavity, and the sliding grooves 16 are arranged in the up and down direction; the limiting unit 60 includes two partition plates 61 and two inserting plates 62. The two partition plates 61 are respectively arranged above the protection cushion plate 20. The two ends of the partition plate 61 are respectively in sliding fit with the two sliding grooves 16. The two partition plates 61 are arranged at intervals in the first horizontal direction, and the first horizontal direction is perpendicular to the connecting direction of the two opposite sliding grooves 16; the two inserting plates 62 are arranged at intervals in the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. A plurality of slots are arranged at intervals along the length direction of the bottom of the inserting plate 62. The two inserting plates 62 and the two partition plates 61 are arranged in a grid-like cross manner. The slots are used to accommodate the partition plates 61. The two inserting plates 62 and the two partition plates 61 enclose a limiting space for accommodating cultural relics.

[0030] As Figure 2 and Figure 4 shown, correspondingly, a plurality of slots can also be arranged along the length direction of the upper part of the partition plate 61. The inserting plate 62 and the partition plate 61 are inserted and matched with each other to form a grid-like limiting space. By changing the relative arrangement of the inserting plate 62 and the partition plate 61, the size of the grid-like limiting space can be changed to adapt to the volume of the cultural relic.

[0031] Please refer to Figure 3 and Figure 4 , the protection cushion plate 20 includes a plate body 21 and an airbag 22. The plate body 21 is arranged at the bottom of the protection cavity. The plate body 21 can be made of metal, high-strength plastic, etc., with high structural strength and not easy to bend and damage; a plurality of airbags 22 are arranged in an array on the upper surface of the plate body 21. The airbag 22 can be a bubble cushion, which can play a role in anti-collision protection.

[0032] Please refer to Figure 1 and Figure 2 , a plurality of first connecting ears 12 are formed around the access opening at the top of the protection box body 10. A plurality of second connecting ears 42 are arranged around the circumferential direction of the bottom edge of the protection cover 40. The first connecting ears 12 and the second connecting ears 42 correspond one by one. The first connecting ear 12 has a threaded hole, and the second connecting ear 42 has a light hole penetrating through its thickness direction. The connecting unit 50 is a bolt. After the bolt penetrates through the light hole on the second connecting part, it is threadedly matched with the threaded hole on the first connecting ear 12.

[0033] Please refer to Figure 5 and Figure 6 , one of the protection cover 40 or the protection box body 10 is provided with a handle 43 for easy handling. Specifically, the handle 43 is arranged on the protection cover 40. An avoidance groove is formed on the upper surface of the protection cover 40. The handle 43 is rotatably arranged in the avoidance groove, and a torsion spring is installed on the rotating shaft of the handle 43. In the natural state, the torsion spring enables the handle 43 to be placed flat in the avoidance groove as Figure 5 shown.

[0034] See also Figure 5 and Figure 6 A connecting hole 44 is provided on the protective cover 40, and the connecting hole 44 is connected to the protective cavity. The anti-oxidation sealing device for cultural relics protection also includes an air pressure detector 70. The air pressure detector 70 includes a detection probe 71 and a display instrument 72. The detection probe 71 is inserted into the connecting hole 44 and is sealed with the connecting hole 44 through a thread. The detection probe 71 can detect the air pressure in the protective cavity. The display instrument 72 is provided on the protective cover 40, and is used to display the detection results of the detection probe 71 and to issue an alarm when the air pressure drops significantly or is lower than the set value. When the displayed air pressure drops, nitrogen can be introduced into the protective box 10 through a gas cylinder to compensate for the escape of gas. The air pressure detector 70 can directly select the existing air pressure detection equipment on the market, which has air pressure detection and display functions, and its specific specifications and models are not limited.

[0035] See also Figure 7 and Figure 8 The horizontal cross-section of the protective cavity gradually shrinks from top to bottom. The shape of the protective box 10 is a quadrangular pyramid. Multiple protective boxes 10 can be stacked together as shown in Figure 7. When not in use, they occupy little space and are easy to carry and transport.

[0036] Because the protective housing 10 and protective cover 40 must maintain a seal during use, they require high dimensional accuracy. If the actual dimensions of the manufactured product deviate significantly from the designed dimensions, air leakage may occur. The protective housing 10 can be integrally manufactured using an injection molding process, which offers high dimensional accuracy, consistent overall structure, and low manufacturing costs. Mass production can be achieved simply by designing an injection mold.

[0037] It is understood that when injection molding is used to manufacture the protective box 10, high-strength engineering plastics can be used to provide sufficient structural strength. Furthermore, embedded steel plates or carbon fiber plates can be installed on the side walls and corners of the protective box 10 during the injection molding process to further enhance the compressive strength of the protective box 10, ensuring that it does not deform excessively during vacuuming and can meet the requirements of use.

[0038] When multiple protective boxes 10 are stacked together, the outer walls of adjacent protective boxes 10 and the interior of the protective cavity fit together, creating a compressive force. Excessive compressive force, or prolonged compressive force, can cause the shape and size of the protective boxes 10 to change, affecting the airtightness of the sealed product. Furthermore, the outer walls of adjacent protective boxes 10 and the interior of the protective cavity fit together, making it easy to remove the lower protective box 10 when removing the upper protective box 10, creating inconvenience.

[0039] To solve the above problems, a circular positioning boss 13 is provided at the bottom of the protection box body 10. The circular positioning boss 13 enables the protection box body 10 to be stably placed on the ground. A positioning groove 14 adapted to the positioning boss 13 is provided on the bottom wall of the protection cavity, and the positioning groove 14 is circular. When the height of the positioning boss 13 is greater than the depth of the positioning groove 14, when two protection box bodies 10 are stacked up and down, the positioning boss 13 of the upper protection box body 10 is inserted into the positioning groove 14 of the lower protection box body 10, and a clearance margin is formed between the outer wall of the upper protection box body 10 and the inner wall of the protection cavity of the lower protection box body 10. With such a setting, when multiple protection box bodies 10 are stacked together, the positioning boss 13 at the bottom of the protection box body 10 is stressed, and the side walls are not stressed, so that deformation will not occur, which helps to ensure the manufacturing and use accuracy of the product. At the same time, due to the existence of the clearance margin, it is convenient to take the protection box bodies 10 one by one, which is more convenient to use.

[0040] Please refer to Figure 7 and Figure 8 , a plurality of reinforcing rib strips 15 are provided at intervals along the circumference of the bottom of the protection cavity. A receiving groove is formed on one side of the reinforcing rib strip 15 adjacent to the protection cushion plate 20, and the receiving groove penetrates through the thickness direction of the reinforcing rib strip 15. The protection cushion plate 20 is received within the area enclosed by the plurality of protection cushion plates 20, and the edge of the protection cushion plate 20 abuts against the side wall of the receiving groove. The reinforcing rib strip 15 is connected between the bottom wall and the side wall of the protection cavity, and a receiving groove is formed on the reinforcing rib strip 15. On the one hand, the reinforcing rib strip 15 can improve the connection strength between the bottom wall and the side wall of the protection box body 10 and is not prone to deformation or fracture. On the other hand, since the protection cushion plate 20 is square, the reinforcing rib strip 15 can limit the protection cushion plate 20 to prevent the protection cushion plate 20 from slipping, so that it can stably support the cultural relics.
