Detailed Implementation

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0023] like Figures 1 to 4 As shown, this embodiment designs a columnar display cabinet that can hide the hinges, including components such as a support column 9, a columnar base 5, a columnar cabinet cover 1, and an arc-shaped cabinet door 3.

[0024] The support column 9 is a tubular structure. The lower end of the support column 9 can be pre-embedded and fixed to the ground, or it can be fixed to the ground via a connecting plate, which is bolted to the ground. This pre-fixed support column 9 provides support and stability to the hinge-concealing cylindrical display case, effectively preventing it from tipping over under external forces and thus protecting the exhibit 12. Cables from the ground can extend from the support column 9 into the cylindrical base 5, supplying power to the various electrical devices within the hinge-concealing cylindrical display case.

[0025] An installation hole is provided at the center of the lower end of the columnar base 5. During installation, the support column 9 is inserted into the installation hole and supports the columnar base 5.

[0026] The cylindrical display case 1 is made of acrylic or tempered glass and is tubular in shape. The interior space of the cylindrical display case 1 is used to place the exhibits 12. The cylindrical display case 1 is coaxially mounted on the upper end of the cylindrical base 5, and the lower end of the cylindrical display case 1 is fixedly connected to the upper end of the cylindrical base 5. A loading / unloading opening is provided on the side of the cylindrical display case 1, through which the exhibits 12 can be loaded or unloaded.

[0027] The curved cabinet door 3 is rotatably connected to the access opening to open and close it. When the curved cabinet door 3 is closed, it can separate the exhibit 12, thereby protecting the exhibit 12. One side of the curved cabinet door 3 is connected to the columnar cabinet cover 1 via hinges 10 at its upper and lower parts, and a lock is provided at the lower part of the other end; an electromagnetic lock 11 is fixedly installed on the side of the top of the columnar base 5, and the lock is used to lock the lock.

[0028] The hinge 10 includes a short connecting rod 101, a long connecting rod 102, a fixed base, and a movable base 103. Both ends of the short connecting rod 101 are rotatably connected to both the fixed base and the movable base 103 via separate pivots. Similarly, both ends of the long connecting rod 102 are rotatably connected to both the fixed base and the movable base 103 via separate pivots. The short connecting rod 101 is shorter than the long connecting rod 102, and the distance between the two pivots on the fixed base is greater than the distance between the two pivots on the movable base 103. The fixed base is fixed inside the access opening, and the movable base 103 is fixed to the curved cabinet door. The fixed base is a side-opening box-shaped structure used to house the short connecting rod 101 and the long connecting rod 102. When the curved cabinet door rotates, the short connecting rod 101 and the long connecting rod 102 can rotate into or out of the fixed base, thus achieving the rotation effect. When the short connecting rod 101 and the long connecting rod 102 rotate into the fixed base, they are well hidden, achieving an aesthetically pleasing effect.

[0029] The upper end of the columnar base 5 has an internal equipment mounting cavity 51, and the upper end of the support column 9 is inserted into the equipment mounting cavity 51. The support column 9 has a central hole, through which ground cables can be introduced into the equipment mounting cavity 51. The power supply 8 can be installed in the equipment mounting cavity 51 to supply power to various power-consuming components.

[0030] A card reader 7 can be installed on the cavity wall of the equipment installation cavity 51. An electromagnetic switch is connected between the power supply 8 and the electromagnetic lock 11. The card reader 7 is connected to the control terminal of the electromagnetic switch. When the RFID card is close to the card reader 7, the card reader 7 identifies and verifies the RFID card. After successful verification, the card reader 7 controls the electromagnetic switch to operate, so that the electromagnetic lock 11 is energized and thus opens the electromagnetic lock 11. The power supply 8 can supply power to the card reader 7 and the electromagnetic lock 11.

[0031] The top of the columnar cabinet cover 1 is provided with a cap 2. The cap 2 can be a flat top structure or an arched top structure, and the cap 2 closes the upper end of the columnar cabinet cover 1.

[0032] A chandelier 4 is installed inside the columnar cabinet 1, and the chandelier 4 is suspended below the ceiling 2. The light from the chandelier 4 shines on the exhibit 12 from top to bottom, thereby supplementing the lighting of the exhibit 12 and improving the display effect of the exhibit 12.

[0033] A detachable exhibit tray 6 is provided at the bottom of the inner cavity of the columnar cabinet cover 1, which is used to support the exhibits 12. At the same time, the surface of the exhibit tray 6 can be covered with velvet cloth to improve the display effect of the exhibits 12.

[0034] An inspection port 52 is provided at the center of the top surface of the columnar base 5. The inspection port 52 is located below the exhibit tray 6 and is covered by the exhibit tray 6. The inspection port 52 communicates with the equipment mounting cavity 51. When it is necessary to repair components such as the power supply 8 in the equipment mounting cavity 51, the exhibit tray 6 can be removed, and then the power supply 8 and other components can be taken out through the inspection port 52 for repair.

[0035] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
