Description

Technical Field

[0001] The invention belongs to the field of protective exhibits, in particular to a multifunctional display cabinet. Background Art

[0002] Display cabinets are special cabinets used to display exhibits, cultural relics or commodities in exhibitions, museums and shops. The upper part of the display cabinet is made of transparent glass or other transparent materials. Placing exhibits in the display cabinet will not affect the viewing of the exhibits, and it can also provide waterproof, dustproof and UV protection for the exhibits.

[0003] Existing display cabinets are movable and immovable. Immovable display cabinets need to be disassembled to move after assembly. Movable display cabinets have poor stability when fixed. To improve stability, accessories must be added to the display cabinet to prevent movement, which is very cumbersome to operate.

[0004] When a movable display cabinet is moved, the exhibits placed in the display cabinet are not well protected. In order to prevent the exhibits from being broken, the exhibits need to be taken out before moving the display cabinet. During the moving process, the display cabinet lacks protection on the periphery. If a collision occurs, the display cabinet will be seriously damaged, making the display cabinet unusable. In severe cases, the display cabinet may be broken, and the splashed fragments may cause harm to the staff.

[0005] To this end, the present invention provides a multifunctional display cabinet. Summary of the Invention

[0040] The annular airbag 23 is made of soft rubber material and can be squeezed and then restored to its original shape after inflation; the display box 2 and the opening and closing plate 3 are both made of acrylic material, which is not as fragile as glass and will not be as sharp as glass even if broken.

[0041] An eighth groove 45 is formed on the outer wall of the display stand 1; one of the second grooves 20 is connected to the eighth groove 45; a fourth rotating shaft 46 is fixedly connected to the second groove 20; a second L-shaped plate 47 is rotatably connected to the outer surface of the fourth rotating shaft 46; the end of the second L-shaped plate 47 away from the fourth rotating shaft 46 is concave, and the concave end of the second L-shaped plate 47 is rotatably connected to a push rod 48, which is opened in the same way as the protective piece, making it convenient to move the display stand 1.

[0042] Working principle: push the third blocking block 43 to open the opening and closing plate 3 and put the exhibit into the middle of the placement table 9 in the display box 2. A group of circular anti-slip grooves 44 are provided in the middle of the top of the display table 1 to place the exhibit accordingly. After placing the exhibit, close the opening and closing plate 3 and turn on the motor 28 so that the exhibit can be rotated for display. When it needs to be moved, turn off the motor 28, push the slide bar 27 to contact the micro-auger piece 29, turn the circular handle 40 to open the limit unit, and start the motor 28 after the bottom plate 10 is released from the limit.

When it is pressed down and contacts the connecting block 16, a group of sponge blocks 12 move into the first cavity to protect the exhibit. At the same time, because the bottom plate 10 is connected to the placement plate 8 through the connecting shaft 7, the bottom plate 10 moves with the placement plate 8. The plate 8 is pressed down to release the limit of the first L-shaped plate 22 and the second L-shaped plate 47, and the protective part is opened. As the placement plate 8 squeezes the annular airbag 23, air enters the airbag 25 through the air tube 26 to protect the display stand 1. A set of universal wheels 11 are fixed under the bottom plate 10. When the bottom plate 10 moves to the bottom end, it pushes the push rod 48 to move. After the movement is completed, the motor 28 is turned on to raise the bottom plate 10 to push the first L-shaped plate 22 and the second L-shaped plate 47 back into the second groove 20. At the same time, the bottom end of the placement plate 8 is fixed to the top of the annular airbag 23. The placement plate 8 rises and drives the annular airbag 23 to draw back the air. Because the side of the first blocking block 34, the second blocking block 37 and the third blocking block 43 that first contacts the other plates is arc-shaped, the bottom plate 10 rises and the limiting unit automatically limits the bottom plate 10. After the limiting is completed, the slide bar 27 is pulled out.
