[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, an electric display stand lifting mechanism and a cake display case include:

[0026] Example 1

[0027] The refrigerator 1 and its top are symmetrically fixedly mounted on two opposite sides. Turntables 3 are axially rotatably mounted on the outer walls of adjacent sides of each turntable 11. Connecting rods 33 arranged in a circular array are fixedly mounted between the two turntables 3. Triangular plates 6 are symmetrically rotatably mounted on the connecting rods 33, and a long plate 61 is fixedly mounted between the two triangular plates 6. By rotating the turntables 3, the multiple connecting rods 33 between the turntables 3 rise and fall sequentially. Under the weight of the long plate 61 and the triangular plates 6, the triangular plates 6 rotate relative to the connecting rods 33, ensuring that the long plate 61 remains parallel to the top of the refrigerator 1. This allows for the raising and lowering of cakes supported on the top of the long plate 61 and maintains stability, enabling cakes to be displayed in turn and avoiding the problem of cakes in corners obstructing the view.

[0028] Example 2

[0029] The top of the upright plate 11 is provided with an arc-shaped part 12, and a front transparent glass plate 2 is fixedly installed between the two upright plates 11. Furthermore, the outer walls of the two adjacent sides of the upright plates 11 are symmetrically provided with arc-shaped grooves 13 that match the arc-shaped part 12. A support block 22 is slidably arranged in the arc-shaped groove 13, and an arc-shaped glass plate 21 is fixedly installed between the two support blocks 22. A rear glass plate 23 is hinged between the two upright plates 11.

[0030] Specifically, the front transparent glass panel 2 is fixed to the upright panel 11 with glue. The front transparent glass panel 2 provides initial shielding for the glass between the two upright panels 11, while the refrigerator 1 cools the area between the two upright panels 11, thus facilitating cake preservation. The curved glass panel 21 is slidably installed within the curved groove 13, and the rear glass panel 23 is hinged between the two upright panels 11. This allows the curved glass panel 21, rear glass panel 23, and front transparent glass panel 2 to work together with the refrigerator 1 to form a closed enclosure structure, facilitating cake refrigeration. Sliding the curved glass panel 21 and flipping the rear glass panel 23 allows for easy opening and removal of the cake between the two upright panels 11, or for storing the cake.

[0031] Example 3

[0032] A weight block 63 is fixedly installed at the bottom of the triangular plate 6. A main motor 32 is fixedly installed inside the refrigerator 1, and the output end of the main motor 32 is driven by a belt through a rotating shaft 31 fixedly installed on one of the turntables 3.

[0033] Specifically, the weight block 63 is bolted to the triangular plate 6. The weight block 63 is used to increase its own weight and improve the stability of the long plate 61 when the turntable 3 rotates. The weight block 63 is an aluminum alloy block. One end of the rotating shaft 31 and the output end of the main motor 32 are respectively fixedly mounted with pulleys. The main motor 32 drives the turntable 3 to rotate through the belt between the two pulleys.

[0034] Example 4

[0035] A curved angle 64 is provided at one corner of the triangle plate 6, and a bearing 52 fixedly installed on the connecting rod 33 is located on one side of the curved angle 64. A locking block 5 is fixedly installed on one side of the outer wall of the triangle plate 6, which is coaxially distributed with the connecting rod 33. The outer wall of the locking block 5 has slots 51 arranged in a circular array. A locking member 4 is slidably arranged in the cutting part 34 symmetrically opened on the outer wall of the connecting rod 33, and a card plate 41 fixedly installed on the locking member 4 is movably arranged in the slot 51.

[0036] Specifically, bearing 52 is sleeved on connecting rod 33. By utilizing bearing 52, friction between triangular plate 6 and connecting rod 33 is reduced, further improving the stability of the long plate 61. Locking member 4 slides within cutting section 34. When the turntable 3 stops rotating, the locking member 4 slides, and the locking plate 41 is inserted into the slot 51, locking the long plate 61 and connecting rod 33, thus facilitating the placement and removal of cakes from the long plate 61 in this stable state. The main motor 32 is a stepper motor to achieve a certain degree of locking rotation when rotation stops. Furthermore, curved protective edges 62 are fixedly installed on opposite sides of the long plate 61. The curved protective edges 62 can shield and protect the cakes on the long plate 61, while also protecting the sides of the long plate 61 from impacts. The curved protective edges 62 are made of wood, and the triangular plate 6 is made of aluminum alloy.

[0037] Working Principle: The two upright panels 11 at the top of the refrigerator 1, connected by a front transparent glass panel 2, a sliding curved glass panel 21, and a flip-up rear glass panel 23, form an openable and closable refrigerated display space. Its core display function is achieved by a main motor 32 driving a rotating shaft 31 via a belt, which in turn drives two turntables 3 and multiple connecting rods 33 to rotate synchronously. Triangular plates 6 are rotatably mounted on the connecting rods 33 via bearings 52, and a long plate 61 is fixedly installed between the two triangular plates 6. As the turntables 3 rotate, causing the connecting rods 33 to rise and fall sequentially, the triangular plates 6 and their bottom weight blocks 63 utilize gravity to allow the triangular plates 6 to rotate automatically relative to the connecting rods 33. This ensures that the long plate 61 remains approximately parallel to the top surface of the refrigerator 1, allowing the cakes supported to be raised and lowered in turn for display without obstruction. In addition, when the turntable 3 stops rotating, the locking member 4 can be manually pushed so that the card plate 41 on it is inserted into the card slot 51 of the locking block 5, locking the long plate 61 and the connecting rod 33 relative to each other, so as to safely pick up and put down the cake.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
