Description

Technical Field

[0001] This utility model relates to the field of art protection technology, and more specifically, to a protective device for sculptural artworks. Background Technology

[0002] Sculpture is a form of visual art, creating three-dimensional images using materials and techniques. Early sculpture primarily employed carving (shaping by subtracting material) and modeling (shaping by layering material) on materials such as stone, metal, wood, and ceramics. However, modernist sculpture enjoys a high degree of freedom in terms of materials and techniques, utilizing carving, welding, molding, or casting on various materials. During exhibitions, protective devices are needed to safeguard the artworks and prevent damage. However, current technologies have the following shortcomings in their application:

[0003] The protective devices used are often fixed in size and cannot be adjusted. For some sculptures with similar length and width but different heights, it is impossible to adjust the height of the transparent protective cover according to the different heights of the sculptures. Traditional transparent protective covers are all directly exposed, which makes the fixed-volume protective devices less applicable and less flexible in use, which is not conducive to practical use.

[0004] Therefore, there is an urgent need for a protective device for sculptural artworks to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that the size of existing protective devices is often fixed and cannot be adjusted.

[0027] Example:

[0028] like Figure 1-5As shown, this embodiment proposes a protective device for sculptural artworks, including a base 1, an outer frame 2 mounted on top of the base 1, four circumferentially arranged pulleys 3 rotatably connected to the top of the outer frame 2, a transparent protective cover 4 positioned directly above the base 1, a connecting plate 5 inside the outer frame 2, a positioning mechanism for fixing the transparent protective cover 4 on the top of the connecting plate 5, two rectangular openings 6 on the transparent protective cover 4, and a placement rack 7 located inside the outer frame 2 fixedly connected to the top of the base 1. Workers place the sculptural artwork on the top of the placement rack 7, and then... A transparent protective cover 4 is placed between the outer frame 2 and the placement rack 7. A fixing frame 8 is fixedly connected to the outer surface of the placement rack 7, so that the bottom of the transparent protective cover 4 is in contact with the upper surface of the connecting plate 5. All four pulleys 3 are in contact with the outer surface of the transparent protective cover 4 for initial positioning. A servo motor 9 is fixedly installed on one side of the fixing frame 8, and the transparent protective cover 4 is fixed by the positioning mechanism at the top of the connecting plate 5. The output end of the servo motor 9 is fixedly connected to a first connecting shaft 10, and a first connecting gear 11 is fixedly sleeved on the first connecting shaft 10. The servo motor 9 is started, which drives the first connecting shaft 10 and the first connecting gear 11 to rotate counterclockwise. A second connecting shaft 12 is rotatably connected to the fixed frame 8. A second connecting gear 13, which meshes with the first connecting gear 11, is fixedly sleeved on the second connecting shaft 12. Through the meshing transmission of the first connecting gear 11, the second connecting gear 13 and the second connecting shaft 12 rotate clockwise. A first rack plate 14 and a second rack plate 15 are fixedly connected to the bottom of the connecting plate 5. The first connecting gear 11 and the second connecting gear 13 respectively mesh with the first rack plate 14 and the second rack plate 15. 4 meshes with the second rack plate 15. The bottom of the connecting plate 5 is provided with a guide mechanism. Through the meshing transmission of the first connecting gear 11 and the first rack plate 14 and the meshing transmission of the second connecting gear 13 and the second rack plate 15, the connecting plate 5 can be driven to move downward. The transparent protective cover 4 moves downward synchronously with the connecting plate 5. According to the actual height of the sculpture, the transparent protective cover 4 is adjusted to a suitable height position, thereby realizing the adjustment of the height position of the transparent protective cover 4, so that it can be flexibly adjusted and used according to sculptures of different height values.

[0029] like Figure 2 and Figure 3As shown, the positioning mechanism includes two first fixing plates 16 symmetrically fixedly installed on the top of the connecting plate 5. An electric push rod 17 is fixedly installed on one side surface of the first fixing plate 16. A second fixing plate 18 is fixedly connected to the push rod end of the electric push rod 17. A positioning block 19 that cooperates with the rectangular opening 6 is fixedly connected to the end face of the second fixing plate 18 away from the electric push rod 17. The two rectangular openings 6 are symmetrically distributed about the central axis of the transparent protective cover 4, and the two rectangular openings 6 correspond to the two positioning blocks 19 respectively. When the two electric push rods 17 are started synchronously, the two electric push rods 17 drive the two second fixing plates 18 to move, so that the two second fixing plates 18 move away from each other. The two positioning blocks 19 move synchronously with the two second fixing plates 18, so that the two positioning blocks 19 are inserted into the two rectangular openings 6 respectively, which can fix the transparent protective cover 4.

[0030] like Figure 3 As shown, the guiding mechanism includes four guide rods 20 fixedly installed at the bottom of the connecting plate 5. All four guide rods 20 movably pass through the fixing frame 8. Through the cooperation of the four guide rods 20 and the fixing frame 8, the connecting plate 5 can be guided to prevent the position of the connecting plate 5 from shifting during the movement.

[0031] like Figure 1 and Figure 2 As shown, the outer surface of the transparent protective cover 4 is in contact with four pulleys 3. The transparent protective cover 4 is located between the outer frame 2 and the placement rack 7. The bottom of the transparent protective cover 4 is in contact with the upper surface of the connecting plate 5. When the bottom of the transparent protective cover 4 is in contact with the upper surface of the connecting plate 5, the four pulleys 3 on the outer frame 2 are in contact with the transparent protective cover 4 from four different directions, which can perform preliminary positioning of the transparent protective cover 4.

[0032] like Figure 3 As shown, the first connecting gear 11 and the second connecting gear 13 have the same specifications, and the first rack plate 14 and the second rack plate 15 are arranged opposite to each other. When the first connecting gear 11 rotates, it drives the second connecting gear 13 to rotate in the opposite direction. The rotation speed of the second connecting gear 13 and the first connecting gear 11 is the same, so that the first rack plate 14 and the second rack plate 15 can move synchronously.

[0033] like Figure 3 As shown, the end of the first connecting shaft 10 away from the servo motor 9 is rotatably connected to the fixed frame 8 through a bearing. The bearing ensures the stability of the first connecting shaft 10 and the first connecting gear 11 when they rotate.

[0034] Specifically, when using this protective device for the sculpture artwork: The servo motor 9 and electric push rod 17 are electrically connected to an external control power supply. The operator first places the sculpture artwork on top of the placement rack 7, then places the transparent protective cover 4 between the outer frame 2 and the placement rack 7, ensuring the bottom of the transparent protective cover 4 is flush with the upper surface of the connecting plate 5, and all four pulleys 3 are flush with the outer surface of the transparent protective cover 4 for initial positioning. The two rectangular openings 6 correspond to the two positioning blocks 19. Then, the two electric push rods 17 are simultaneously activated, driving the two second fixing plates 18 to move away from each other. The two positioning blocks 19 move synchronously with the two second fixing plates 18, inserting themselves into the two rectangular openings 6 to fix the transparent protective cover 4. Then, the servo motor 9 is activated again. Motor 9, via servo motor 9, drives the first connecting shaft 10 and the first connecting gear 11 to rotate counterclockwise. Through the meshing transmission of the first connecting gear 11, it drives the second connecting gear 13 and the second connecting shaft 12 to rotate clockwise. Through the meshing transmission of the first connecting gear 11 and the first rack plate 14, and the meshing transmission of the second connecting gear 13 and the second rack plate 15, the connecting plate 5 can be moved downward. The transparent protective cover 4 moves downward synchronously with the connecting plate 5. Through the cooperation of four guide rods 20 and the fixing frame 8, the connecting plate 5 can be guided. According to the actual height of the sculpture, the transparent protective cover 4 can be adjusted to a suitable height position, thereby realizing the height adjustment of the transparent protective cover 4. This allows for flexible adjustment and use according to sculptures of different heights. The overall size of the device is adjustable, making it more widely applicable and conducive to practical promotion and use.
