[0001] The present invention relates to the technical field of exhibition equipment, and particularly relates to an adjustable device for exhibiting exhibits. Background Art

[0002] When museums exhibit precious antiques or exhibits, adjustable exhibition equipment is usually used, so that the exhibits can be safely and completely displayed, and the viewing effect for viewers is better.

[0003] For example, an adjustable device for museum display and exhibition disclosed in Chinese Patent Publication No. (CN215348028U) records: "Comprising an equipment box, a forward and reverse motor is fixedly connected to the bottom surface inside the equipment box, and a worm is fixedly connected to the output shaft of the forward and reverse motor. This adjustable device for museum display and exhibition can drive a moving plate to move up and down through the settings of the forward and reverse motor, worm, worm gear, bevel gear one, bevel gear two, bevel gear three, rotating shaft one, rotating shaft two, rotating rod, gear, toothed bar, limiting rod, and connecting rod, so as to achieve the purpose of adjusting the overall height of the device, thereby increasing the practicability of the device during use. Through the settings of a low-speed motor, bevel gear four, bevel gear five, fixed shaft, and placement plate, the exhibits placed on the placement plate can be driven to rotate, so that the exhibition items can be displayed to audiences in all directions, further increasing the practicability of the device."

[0004] To sum up, the device still has the following technical problems: The above device realizes the display of exhibits at different angles through multi-directional adjustment. However, exhibits are generally placed inside the display cabinet, and only glass protection is provided outside some display cabinets. If there is a collision or vibration, the exhibits inside the display cabinet may shake. If the shaking amplitude is large, the exhibits are very likely to be damaged.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As described in the background art, the above device realizes the display of exhibits at different angles through multi-directional adjustment. However, the exhibits are generally placed inside the display cabinet, and only glass protection is provided outside some display cabinets. If there is a collision or vibration, the exhibits inside the display cabinet may shake. If the shaking amplitude is large, the exhibits are very likely to be damaged. Moreover, the exhibits generally have high economic value and commemorative significance. If theft occurs, there will be a large economic loss.

[0039] To solve this technical problem, the present invention provides an adjustable device for exhibit exhibition, which is applied to museum exhibitions and the protection of exhibition items.

[0047] Through the above structural design, when the exhibit is to be displayed, it is placed on the top surface of the exhibit placement seat 9. After completion, the servo motor 6 is turned on. The servo motor 6 drives the insertion rods 7 to rotate. The rotation of the insertion rods 7 drives the exhibit placement seat 9 to rotate through cooperation with the slots 10, so as to realize the rotational display of the exhibit.

[0048] Embodiment 2:

[0049] The adjustable device for exhibit display provided in Embodiment 1 is further optimized. Specifically, as Figures 5-10 shown, the overall body protection mechanism 2 includes sliding sleeves 11 fixedly connected to the four corners of the inner wall of the display stand 4. Longitudinal guide grooves 12 are formed on the surface of the sliding sleeves 11. A top rod 13 is slidably connected to the inner wall of the sliding sleeves 11. A protection ceiling 14 is fixedly connected to one end of the top rod 13 away from the sliding sleeves 11.

[0050] Specifically, side insertion protection plates 15 are fixedly connected to the four sides of the protection ceiling 14. A glass through groove 16 is formed on the top surface of the protection ceiling 14. Glass is fixedly arranged on the four sides of the top surface of the display stand 4, and the top end of the glass passes through the glass through groove 16 and is arranged above the protection ceiling 14.

[0051] Specifically, a retaining wall 17 is fixedly connected to the surface of the display stand 4. A rubber airbag 18 is fixedly connected inside the retaining wall 17. Light rods 19 are fixedly connected to the four corners inside the retaining wall 17. A pressing ring 20 is slidably connected to the surface of the light rods 19. The pressing ring 20 is fixedly connected to the top surface of the rubber airbag 18.

[0052] Specifically, a hinge seat 26 is fixedly connected to the surface of the retaining wall 17. A flap 27 is rotatably connected inside the hinge seat 26. A torsion spring 28 is arranged inside the hinge seat 26. The two ends of the torsion spring 28 are respectively fixedly connected to the hinge seat 26 and the flap 27. A toothed plate 25 is fixedly connected to the surface of the side insertion protection plate 15. The toothed plate 25 is snap-connected to the flap 27.

[0053] Specifically, an angle iron 21 is fixedly connected to the inner wall of the display stand 4. One side of the angle iron 21 away from the display stand 4 is fixedly connected to a first air guide cylinder 22. A first sliding rod 23 is slidably connected to the inner wall of the first air guide cylinder 22. One end of the first sliding rod 23 away from the first air guide cylinder 22 is fixedly connected to an arc-shaped pressing plate 40. A first air guide pipe 24 is fixedly connected to the surface of the first air guide cylinder 22. One end of the first air guide pipe 24 away from the first air guide cylinder 22 is fixedly connected to a rubber air bag 18. The rubber air bag 18 and the first air guide cylinder 22 are communicated through the first air guide pipe 24.

[0054] Specifically, an electric telescopic pump 29 is fixedly connected to the surface of the motor support rod 5. The output ends on both sides of the electric telescopic pump 29 are fixedly connected to vertical rods 30. One end of the vertical rod 30 away from the electric telescopic pump 29 is fixedly connected to a support plate 31.

[0055] Specifically, a connecting cross bar 32 is slidably connected to the inner wall of the longitudinal guide groove 12. Both ends of the connecting cross bar 32 are fixedly connected to the bottom ends of the two sliding sleeves 11. The support plate 31 is in close contact with the surface of the connecting cross bar 32, and the support plate 31 is arranged at the bottom end of the connecting cross bar 32.

[0056] Specifically, towing rods 33 are symmetrically fixedly connected to the surface of the connecting cross bar 32. The towing rods 33 are arranged at the bottom end of the exhibit placement seat 9 and are in close contact with the bottom surface of the exhibit placement seat 9.

[0057] Through the above structural design, if vibration occurs, the vibration sensor transmits the vibration signal to the single-chip microcomputer. The single-chip microcomputer controls the electric telescopic pump 29 to start and contract its two ends inward. While the output ends of the electric telescopic pump 29 contract, they drive the vertical rod 30 and the support plate 31 to move out from the bottom end of the connecting cross bar 32. At this time, the bottom of the connecting cross bar 32 loses support, and the connecting cross bar 32 slides downward on the inner wall of the longitudinal guide groove 12. While the support plate 31 moves, it drives the ejector rod 13 to slide downward on the inner wall of the sliding sleeve 11. While the sliding sleeve 11 slides, it drives the protective ceiling 14 to move downward. While the protective ceiling 14 moves downward, the side part of its outer surface inserts the protective plate 15 into the inside of the enclosure 17 and squeezes the pressure ring 20. The pressure ring 20 is squeezed and slides into the inside of the enclosure 17 on the surface of the optical rod 19. While the pressure ring 20 moves, it squeezes the rubber air bag 18 to achieve buffering for the downward fall of the side inserted protective plate 15;

[0058] While the side inserted protective plate 15 descends, the toothed plate 25 on its outer surface is engaged with the flap 27 to lock the protective ceiling 14;

[0059] While the connecting crossbar 32 descends, it drives the towing bar 33 to move downward. At this time, the bottom of the exhibit placing seat 9 loses support, and the exhibit placing seat 9 slides downward on the surface of the insertion rod 7 and drives the exhibit to descend simultaneously. The rubber airbag 18 is squeezed, and the gas inside is transported into the interior of the first air guide cylinder 22 through the first air guide pipe 24. The gas enters the interior of the first air guide cylinder 22 and pushes the first sliding rod 23 to move inward. The first sliding rod 23 drives the arc-shaped pressing plate 40 to move inward and squeeze and lock the exhibit at the same time, so as to realize the rapid protection of the exhibit.

[0060] Embodiment 3:

[0061] The adjustable device for exhibit exhibition provided in Embodiment 1 and Embodiment 2 is further optimized. Specifically, as Figures 8-11 shown, a power interface 35 is fixedly connected to the surface of the display stand 4, and a second air guide cylinder 36 is fixedly connected to the inner wall of the display stand 4. A second sliding rod 37 is slidably connected to the interior of the second air guide cylinder 36. The second sliding rod 37 is slidably connected to the interior of the display stand 4. One end of the second sliding rod 37 away from the second air guide cylinder 36 is fixedly connected to an annular pushing frame 38. The annular pushing frame 38 is in close contact with the outer surface of the display stand 4. An external power supply 39 is inserted into the power interface 35, and the power interface 35 is electrically connected to the power interface 35. A second air guide pipe 34 is fixedly connected to the surface of the second air guide cylinder 36. One end of the second air guide pipe 34 away from the second air guide cylinder 36 is fixedly connected to the rubber airbag 18. The second air guide cylinder 36 and the rubber airbag 18 are communicated through the second air guide pipe 34.

[0062] Through the above structural design, after the rubber airbag 18 is squeezed, the gas enters the interior of the second air guide cylinder 36 through the second air guide pipe 34. The gas enters the interior of the second air guide cylinder 36 and pushes the second sliding rod 37 to slide outward from the second air guide cylinder 36. While the second sliding rod 37 moves, it pushes the annular pushing frame 38 away from the display stand 4. While the annular pushing frame 38 moves, it pushes the external power supply 39 to separate from the power interface 35, so as to cut off the power supply inside the device.
