[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the proportions shown in the drawings are not exactly the same as the actual proportions and are only used as examples. In the description of the present invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0016] This invention provides a foldable and extendable display case for exhibits, such as... Figure 1-3 As shown, the system includes a support rod 1, a sliding ring 2 slidably mounted on the support rod 1, a central hinge seat 3 at the top of the support rod 1, several base plates 4 hinged to the central hinge seat 3, a connecting rod hinge seat 5 on the bottom surface of the base plate 4, and a connecting rod 6 hinged to the connecting rod hinge seat 5. One end of the connecting rod 6 is hinged to the connecting rod hinge seat 5, and the other end is hinged to the side of the sliding ring 2. A display cabinet 7 is mounted on the upper surface of the base plate 4, and a base 8 is mounted below the support rod 1. An electric push cylinder 9 is mounted on the base 8, and the output end of the electric push cylinder 9 is connected to the bottom surface of the sliding ring 2. The support rod 1, sliding ring 2, base plate 4, and connecting rod 6 form a structure similar to an umbrella handle and ribs. By moving the sliding ring 2 up and down through the electric push cylinder 9, the base plate 4 can be closed and opened, thereby causing the display cabinet on the base plate 4 to close and open. The electric push cylinder 9 and the base 8 are detachably connected by bolts, which is a conventional fixed connection structure and will not be described in detail.

[0017] It should be noted that the top view of the display cabinet 7 is trapezoidal, so that the display cabinet 7 will not interfere with each other when it is opened. The display cabinet 7 includes an upper fixed plate 10 and a lower fixed plate 11. A connecting plate 12 and a telescopic plate 13 are provided between the upper fixed plate 10 and the lower fixed plate 11. The connecting plate 12 forms the upper base of the trapezoid, and the telescopic plate 13 forms the lower base of the trapezoid.

[0018] Reference Appendix Figure 1-3 Both sides of the upper fixed plate 10 and the lower fixed plate 11 are rotatably connected to triangular plates 14. The top view of the triangular plate 14 is a right triangle. One right-angled side of the triangular plate 14 is rotatably connected to the side of the upper and lower fixed plates, and the other right-angled side is collinear with the telescopic plate 13. Side plates 15 are rotatably connected to both sides of the connecting plate 13. The side plates 15 are trapezoidal legs. The maximum rotation angle of the side plates 15 is when the top view of the side plates 15 coincides with the hypotenuse of the triangular plates 15. When the display cabinet 7 moves forward with the base plate 4, the side plates 15 and triangular plates 14 of the display cabinet 7 need to be folded up first to avoid interference between adjacent display cabinets 7 after folding.

[0019] It should be noted that the distance between the triangular plates 14 rotatably connected to both sides of the lower fixed plate 11 and the lower fixed plate 11 is greater than the distance between the triangular plates 14 rotatably connected to both sides of the upper fixed plate 11 and the upper fixed plate 11, so that the side plates 15 and the triangular plates 14 are folded together.

[0020] When folding the side plate 15 and the triangular plate 14, first fold the two sides of the telescopic plate 12, then push the side plate 15 inward so that the inner wall of the side plate 15 abuts against the two sides of the telescopic plate 12. Then, first fold the triangular plates 14 on both sides of the fixing plate 11 to the outside of the side plate 15, and then fold the triangular plates 14 on both sides of the lower fixing plate 11 to the outside of the triangular plate 14. Then, connect cable ties or ropes between the connecting post 16 on the bottom surface of the triangular plate 14 and the connecting post 16 on the upper end surface of the upper fixing plate 10 for fixation. The cable ties or ropes are embedded in the groove 17. In the unfolded state, cable ties or ropes also need to be connected between the connecting post 16 of the side plate 15 and the connecting post 16 on the bottom surface of the triangular plate 14 to prevent the side plate 15 from being pushed and rotating inward.

[0021] This invention discloses a foldable and extendable display case. When folded, it has a compact volume, significantly reducing logistics and warehousing costs. The entire process requires no tools and can be completed by 1-2 people in 5-10 minutes, greatly improving work efficiency. By changing the length of the support rods and the size of the display case, display cases of different sizes and heights can be easily derived to adapt to various exhibit needs. It transforms the complex spatial construction process into simple, linear mechanical movements, perfectly achieving a balance between convenience and stability.

[0022] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
