In this embodiment, it is used to place wine bottles. A placement groove 41 is arranged on the top of the pedestal 4 to improve the stability of the wine bottles. A number of opening and closing members 5 are arranged around the pedestal 4 through a rotating shaft 51. In order to make the opening and closing members 5 more beautiful when opening and closing, the shape of the opening and closing members 5 can be one or more of a stepped shape and a petal shape. In this embodiment, the opening and closing members 5 are stepped, and the number thereof is 3. The stepped opening and closing members 5 are used to improve the artistic beauty. A linkage mechanism is provided in the pedestal 4, which transmits and connects the opening and closing member 5 and the cover 3. When the cover 3 is rotated to open, the linkage mechanism drives the opening and closing member 5 to rotate and expand, thereby improving the decoration and display effect of the object (wine bottle) and attracting people's attention. When the cover 3 is rotated to close, the linkage mechanism drives the opening and closing member 5 to rotate together, which is interesting and has a protective effect on the object (wine bottle) and improves the stability of the object (wine bottle).

[0037] This embodiment further, please refer to Figure 3-Figure 5 , the linkage mechanism includes a turntable 61, a T-shaped linkage member 62, a plurality of transmission components 63 and a pair of opening and closing pieces 64;

[0038] The turntable 61 is rotatably disposed in the center of the base 4; a transmission assembly 63 is disposed between the opening and closing member 5 and the turntable 61. When the turntable 61 rotates, the transmission assembly 63 drives the opening and closing member 5 to rotate and expand or close.

[0039] The pair of opening and closing pieces 64 can be rotatably arranged on one side of the base 4 near the rear side plate 2, and the pair of opening and closing pieces 64 are symmetrically arranged on the left and right sides of the base 4. The side wall of the base 4 is provided with an opening 40 for the opening and closing piece 64 to pass through. One side of the opening and closing piece 64 passes through the opening 40 and is connected to the adjacent cover 3. The other side of the opening and closing piece 64 is provided with a stopper 641. The direction of the line connecting the pair of opening and closing pieces 64 is defined as the x-direction, and the direction perpendicular to the x-direction on the horizontal plane is defined as the y-direction.

[0040] The T-shaped linkage 62 is slidably disposed in the pedestal 4 along the y direction, and a first spring 65 is disposed between the T-shaped linkage 62 and the pedestal 4 along the y direction. Figure 3As shown, the base 4 is equipped with a fixing rod 511, and the T-shaped linkage 62 is provided with a mounting rod 521. One end of the first spring 65 is assembled on the fixing rod 511 and the other end is assembled on the mounting rod 521; the T-shaped linkage 62 is movably connected to the base 4, so as to drive the turntable 61 to rotate when the T-shaped linkage 62 moves along the y direction. Specifically, the T-shaped linkage 62 is provided with a strip hole 620 along the x direction, and the turntable 61 is provided with a movable rod 610, and the movable rod 610 is slidably arranged in the strip hole 620. When the T-shaped linkage 62 moves along the y direction, the movable rod 610 and the turntable 61 are driven to rotate under the action of the strip hole 620, and the movable rod 610 slides in the strip hole 620; the two ends of the T-shaped linkage 62 abut against the stop block 641, and when the opening and closing piece 64 rotates When the cover 3 is moving, the stopper 641 drives the T-shaped linkage 62 to move along the y direction, and when the cover 3 is closed, the cover 3 drives the opening and closing piece 64 to rotate, and the stopper 641 drives the T-shaped linkage 62 to move along the y direction, so that the first spring 65 is deformed and is in an energy storage state. At the same time, the T-shaped linkage 62 moves along the y direction to drive the turntable 61 to rotate, and the transmission assembly 63 drives the opening and closing piece 5 to rotate and close, thereby achieving the effect of closing the cover 3 and automatically closing the opening and closing piece 5; when the cover 3 is unfolded, the cover 3 drives the opening and closing piece 64 to rotate, and the first spring 65 releases elastic potential energy, and under the action of the elastic force of the first spring 65, drives the T-shaped linkage 62 to move in the opposite direction of the y direction and then drives the turntable 61 to reverse, and the transmission assembly 63 drives the opening and closing piece 5 to rotate and unfold, thereby achieving the effect of opening the cover 3 and automatically unfolding the opening and closing piece 5.

[0041] This embodiment further refers to Figure 3 A second spring 66 is arranged between the pair of stoppers 641. By utilizing the second spring 66, when the cover 3 is closed, the opening and closing piece 64 rotates to drive the second spring 66 to stretch and store spring potential energy, so that when the cover 3 is opened, the second spring 66 releases the spring potential energy to assist in opening the cover 3, making it more convenient to open the cover 3. At the same time, under the connecting action of the second spring 66, the cover 3 on both sides can be opened synchronously. Even if only one side of the cover 3 is opened, the cover 3 on the other side will be opened synchronously.

[0042] This embodiment further, please refer to Figure 3 and Figure 4The transmission assembly 63 includes a rotating rod 631 and a linkage rod 632; the rotating rod 631 can be rotatably arranged in the base 4, and the rotating rod 631 is parallel to the adjacent rotating shaft 51, and a driving assembly is provided between the rotating rod 631 and the rotating shaft 51. The driving assembly is used to synchronously transmit the rotating rod 631 and the rotating shaft 51, and the outer wall of the rotating rod 631 is provided with a driving arm 633, and the driving arm 633 is L-shaped; one end of the linkage rod 632 is rotatably connected to the turntable 61, and the other end of the linkage rod 632 is rotatably connected to the driving arm 633. Specifically, the end of the linkage rod 632 is provided with a connecting hole, and the linkage rod 632 is movably connected to the driving arm 633 through the connecting hole. When the turntable 61 rotates, the driving arm 633 and the rotating rod 631 are driven to rotate under the action of the linkage rod 632, thereby driving the rotating shaft 51 to rotate under the action of the driving assembly, and then driving the opening and closing member 5 to rotate to expand or close. Specifically, the drive assembly includes a meshing first gear 634 and a second gear 635. The first gear 634 is disposed on the rotating shaft 51, and the second gear 635 is disposed on the rotating rod 631. When the rotating rod 631 rotates, the second gear 635 rotates, thereby driving the first gear 634 and the rotating shaft 51 to rotate. In this embodiment, the diameter of the second gear 635 is larger than that of the first gear 634, thereby increasing the rotation angle of the opening and closing member 5. To reduce manufacturing costs, the second gear 635 is fan-shaped.

[0043] This embodiment further, please refer to Figure 3 and Figure 5 The T-shaped linkage 62 includes a horizontal rod 621 and a vertical rod 622 connected perpendicularly to each other. A plurality of first guide grooves 42 are arranged in the y direction in the base 4. The vertical rod 622 is slidably arranged in the first guide groove 42. The horizontal rod 621 is symmetrically arranged with a pair of second guide grooves 623 with the vertical rod 622 as the center. A pair of limit blocks 43 matching the second guide grooves 623 are arranged in the base 4. The limit blocks 43 are slidably arranged in the second guide grooves 623, thereby utilizing the first guide grooves 42 and the second guide grooves 623 to improve the stability of the T-shaped linkage 62 during movement.

[0044] This embodiment further, please refer to Figure 3 and Figure 5 Therefore, the vertical rod 622 is further provided with a plurality of limiting holes 624 along the y direction, and a limiting rod 44 is slidably arranged in the limiting hole 624. The limiting rod 44 is fixedly connected to the base 4. The limiting rod 44 and the limiting hole 624 are used to limit the movement distance of the T-shaped linkage 62, thereby limiting the expansion angle of the opening and closing piece 64 and the cover 3, thereby avoiding the situation where the cover 3 is artificially expanded at an excessive angle and the box body is damaged.

[0045] The use process of the present invention is as follows:

[0046] When the user closes the cover 3, the cover 3 drives the opening and closing piece 64 to rotate, the second spring 66 stretches to store spring potential energy, and the stopper 641 drives the T-shaped linkage 62 to move in the y direction, so that the first spring 65 assembly gradually stretches to store spring potential energy. At the same time, the T-shaped linkage 62 moves in the y direction to drive the turntable 61 to rotate, and drives the linkage rod 632 to move, thereby driving the driving arm 633 and the rotating rod 631 to rotate, and the second gear 635 drives the first gear 634 to rotate, and then the rotating shaft 51 rotates to drive the opening and closing piece 5 to close; thus, the cover 3 is closed and the opening and closing piece 5 slowly and automatically closes.

[0047] When the user opens the cover 3, the cover 3 drives the opening and closing piece 64 to rotate, and the first spring 65 releases elastic potential energy to open the cover 3. At the same time, the first spring 65 releases elastic potential energy, and under the elastic force of the first spring 65, the T-shaped linkage 62 is driven to move in the opposite direction along the y direction, thereby driving the turntable 61 to reverse, driving the linkage rod 632 to move, thereby driving the driving arm 633 and the rotating rod 631 to rotate, and the second gear 635 drives the first gear 634 to rotate, and then the rotating shaft 51 rotates to drive the opening and closing piece 5 to unfold, thereby achieving the effect of opening the cover 3 and the opening and closing piece 5 slowly and automatically unfolding.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
