[0007] As a preferred embodiment of the invention, the lifting assembly includes a motor, the bottom of which is fixedly connected to the inner wall of the adjusting groove, an adjusting plate is movably connected to the inner cavity of the adjusting hole, the left and right sides of the adjusting plate are fixedly connected to the lifting tube, a screw is fixedly connected to the output end of the motor, and the top of the screw passes through the adjusting plate and is rotatably connected to the inner wall of the adjusting groove through a bearing seat.

[0008] As a preferred embodiment of the invention, each of the hexagonal corners of the platform surface is provided with a mating groove, the inner cavity of the mating groove is provided with a flip box, and both sides of the inner cavity of the flip box are provided with anti-detachment components.

[0009] As a preferred embodiment of the invention, the bottom of the flip box is provided with a toothed groove, and the number of toothed grooves is multiple. A toothed plate is movably connected to the bottom of the flip box, and the top of the toothed plate is engaged with the toothed groove.

[0010] As a preferred embodiment of the invention, the top of the toothed plate is provided with an extrusion plate, the top of the extrusion plate is movably connected to an extrusion rod, the inner cavity of the movable groove is movably connected to a linkage plate, the side of the extrusion rod near the linkage plate is fixedly connected to the linkage plate, the bottom of the linkage plate is fixedly connected to a movable rod, and the bottom of the movable rod passes through the movable groove and is fixedly connected to a support rod.

[0011] As a preferred embodiment of the invention, the rebound assembly includes a fixed plate, the bottom of which is fixedly connected to the toothed plate. A stroke hole is provided on the side of the fixed plate near the extrusion plate. A stroke rod is movably connected to the inner cavity of the stroke hole. A spring is sleeved on the surface of the stroke rod. The side of the stroke rod near the inner wall of the receiving groove is fixedly connected to the inner wall of the receiving groove.

[0012] As a preferred embodiment of the invention, the anti-detachment component includes an anti-detachment groove, which is formed on both sides of the inner cavity of the flip box. An anti-detachment rod is movably connected to the inner cavity of the anti-detachment groove. A torsion spring is sleeved on the surface of the anti-detachment rod. The side of the torsion spring near the anti-detachment rod is fixedly connected to the anti-detachment rod, and the side of the torsion spring near the inner wall of the anti-detachment groove is fixedly connected to the inner wall of the anti-detachment groove. The side of the anti-detachment rod away from the toothed plate passes through the anti-detachment groove and is fixedly connected to the mating groove.

[0013] As a preferred embodiment of the present invention, the first step is: when it is necessary to control the rise of the artwork display stand, first turn on the motor to drive the screw to rotate. The rotation of the screw will drive the adjustment plate to rise. The movement of the adjustment plate will drive the lifting tube on the outer surface of the support rod to rise. The rise of the lifting tube will drive the platform to rise. Step 2: When the platform rises, it will cause the pressing plate to rise and press against the pressing rod on the linkage plate at the top of the moving rod. At this time, the pressing rod presses against the inclined surface on the linkage plate, which will cause the six toothed plates to move closer to each other. The movement of the toothed plates will drive the fixed plate, and the fixed plate will press the spring following the stroke rod. Step 3: When the toothed plate moves, it engages with the toothed groove at the bottom of the flip box. This will cause the flip box to rotate 90 degrees and unfold. Then, the items to be displayed can be placed in the placement slot on the top of the connecting plate and inside the flip box. Step 4: When the flip box rotates, the torsion spring can be twisted around the anti-detachment rod. When the screw rotates and drives the display stand back to its original position, the torsion spring will undergo elastic deformation and drive the flip box back to its original position for storage.

[0014] Compared with existing technologies, the beneficial effects of the invention are as follows: 1. The invention solves the problems of fixed-height exhibition stands being unable to meet different display needs, having a low reusability rate, and being unable to lower the height to accommodate special audiences (children's exhibition areas, barrier-free exhibitions), resulting in an insufficient viewing experience, by setting up movable slots, movable holes, receiving slots, spring-loaded components, connecting plates, placement slots, motors, adjusting plates, screws, mating slots, flip boxes, and anti-detachment components. It achieves the effect of adjustment and storage.

[0015] 2. The invention, through the second embodiment, uses a motor-driven screw to rotate, which in turn drives the adjusting plate and lifting tube to simultaneously raise and lower the hexagonal platform. The platform height can be freely switched. During the platform raising process, the movable rod remains stationary. The platform rises, causing the extrusion plate to push the extrusion rod. The inclined plane transmission drives the six sets of toothed plates to converge towards the center synchronously. The toothed plates move synchronously in six directions by relying on the central linkage plate. The six sets of flip boxes open and close synchronously. The opening and closing of the display boxes is achieved by the mechanical transmission of the platform's lifting mechanism, without the need for an additional independent drive motor.

[0016] 3. In the third embodiment of the invention, when the display stand is raised, the toothed plate retracts and compresses the spring to store elastic potential energy. When the display stand is lowered and reset, the spring releases its elastic force to push the fixed plate and toothed plate to reset outward. When the flip box flips outward, the torsion spring undergoes elastic torsion to store elastic force. After the display stand is lowered, the spring and the torsion spring form a dual reset driving force. The forces on both sides are applied simultaneously to drive the display box to rotate smoothly, and the storage action is smooth and without jamming. Attached Figure Description

[0023] Example 1

[0024] Reference Figure 1-6 The first embodiment of the invention provides a liftable artwork display stand and its usage method, including a support plate 1, a support rod 2, a lifting tube 3 and a platform 4. The top of the support plate 1 is fixedly connected to the bottom of the support rod 2, the lifting tube 3 is sleeved on the surface of the support rod 2, and the top of the lifting tube 3 is fixedly connected to the bottom of the platform 4. The inner cavity of the support rod 2 is provided with an adjustment groove 5. The left and right sides of the inner cavity of the adjustment groove 5 are provided with adjustment holes 6. The inner cavity of the adjustment groove 5 is provided with a lifting component 7. The inner cavity of the platform 4 is provided with a movable groove 8. The hexagonal corners of the inner cavity of the movable groove 8 are provided with movable holes 9. The top of the movable hole 9 is provided with a receiving groove 10. Springback assembly 11 is disposed in the inner cavity of receiving groove 10; A connecting plate 12 is provided on the top of the platform 4, and a placement groove 13 is provided on the top of the connecting plate 12; The lifting assembly 7 includes a motor 71, the bottom of which is fixedly connected to the inner wall of the adjusting groove 5. An adjusting plate 72 is movably connected to the inner cavity of the adjusting hole 6. The left and right sides of the adjusting plate 72 are fixedly connected to the lifting tube 3. A screw 73 is fixedly connected to the output end of the motor 71. The top of the screw 73 passes through the adjusting plate 72 and is rotatably connected to the inner wall of the adjusting groove 5 through a bearing seat.

[0025] Specifically, when it is necessary to control the rise of the artwork display stand, first turn on the motor 71 to drive the screw 73 to rotate. The rotation of the screw 73 will drive the adjustment plate 72 to rise. The movement of the adjustment plate 72 will drive the lifting tube 3 on the outer surface of the support rod 2 to rise. The rise of the lifting tube 3 will drive the platform 4 to rise.

[0026] Example 2

[0027] The second embodiment of the invention provides a height-adjustable art display stand and its usage method. The hexagonal corners of the stand body 4 are provided with mating grooves 14. A flip box 15 is provided within the inner cavity of the mating groove 14. Anti-detachment components 16 are provided on both sides of the inner cavity of the flip box 15. Multiple toothed grooves 17 are provided at the bottom of the flip box 15. A toothed plate 18 is movably connected to the bottom of the flip box 15. The top of the toothed plate 18 engages with the toothed groove 17. A pressing plate 19 is provided at the top of the toothed plate 18. A pressing rod 20 is movably connected to the top of the pressing plate 19. A linkage plate 21 is movably connected to the inner cavity of the movable groove 8. The side of the pressing rod 20 closest to the linkage plate 21 is fixedly connected to the linkage plate 21. A movable rod 22 is fixedly connected to the bottom of the linkage plate 21. The bottom of the movable rod 22 passes through the movable groove 8 and is fixedly connected to the support rod 2.

[0028] Specifically, in the second embodiment, the motor 71 drives the screw 73 to rotate, which in turn drives the adjusting plate 72 and the lifting tube 3 to simultaneously raise and lower the hexagonal platform 4, allowing for free switching of the platform height. During the platform raising process, the movable rod 22 remains stationary, and the platform 4 rises, causing the extrusion plate 19 to push the extrusion rod 20. The inclined plane transmission drives the six sets of toothed plates 18 to converge towards the center simultaneously. The central linkage plate 21 enables the toothed plates 18 to move synchronously in six directions, and the six sets of flip boxes 15 to open and close synchronously. The opening and closing of the display boxes is achieved by the mechanical transmission of the platform's lifting mechanism, without the need for an additional independent drive motor 71.

[0029] Furthermore, when the platform 4 rises, it will cause the pressing plate 19 to rise and press against the pressing rod 20 on the top linkage plate 21 of the movable rod 22. At this time, the pressing rod 20 presses against the inclined surface on the linkage plate 21, which will cause the six toothed plates 18 to move closer to each other. The movement of the toothed plates 18 will drive the fixed plate 111. The fixed plate 111 will press the spring 114 following the stroke rod 113. When the toothed plates 18 move, they will engage with the toothed groove 17 at the bottom of the flip box 15. At this time, the flip box 15 can be rotated ninety degrees to unfold. Then, the items to be displayed can be placed in the placement slot 13 on the top of the connecting plate 12 and in the flip box 15.

[0030] Example 3

[0031] A third embodiment of the invention provides a height-adjustable artwork display stand and its usage method. The spring-loaded assembly 11 includes a fixed plate 111, the bottom of which is fixedly connected to a toothed plate 18. A travel hole 112 is formed on the side of the fixed plate 111 near the pressing plate 19. A travel rod 113 is movably connected to the inner cavity of the travel hole 112. A spring 114 is sleeved on the surface of the travel rod 113. The side of the travel rod 113 near the inner wall of the receiving groove 10 is fixedly connected to the inner wall of the receiving groove 10. An anti-detachment assembly 1... 6 includes an anti-detachment groove 161, which is formed on both sides of the inner cavity of the flip box 15. An anti-detachment rod 162 is movably connected to the inner cavity of the anti-detachment groove 161. A torsion spring 163 is sleeved on the surface of the anti-detachment rod 162. The side of the torsion spring 163 near the anti-detachment rod 162 is fixedly connected to the anti-detachment rod 162. The side of the torsion spring 163 near the inner wall of the anti-detachment groove 161 is fixedly connected to the inner wall of the anti-detachment groove 161. The side of the anti-detachment rod 162 away from the toothed plate 18 passes through the anti-detachment groove 161 and is fixedly connected to the mating groove 14.

[0032] Specifically, by setting the third embodiment, when the display stand is raised, the toothed plate 18 retracts and compresses the spring 114 to store elastic potential energy. When the display stand is lowered and reset, the spring 114 releases its elastic force to push the fixed plate 111 and the toothed plate 18 to reset outward. When the flip box 15 flips outward, the torsion spring 163 undergoes elastic torsion to store elastic force. After the display stand is lowered, the spring 114 and the torsion spring 163 form a dual reset driving force. The forces on both sides are applied simultaneously to drive the display box to rotate smoothly, and the storage action is smooth and without jamming.

[0033] Furthermore, when the flip box 15 rotates, it can twist the torsion spring 163 around the anti-detachment rod 162. When the screw 73 rotates and drives the display stand back to its original position, the torsion spring 163 will undergo elastic deformation and drive the flip box 15 back to its original position for storage.

[0034] Working principle: When it is necessary to control the raising of the artwork display stand, first turn on the motor 71 to drive the screw 73 to rotate. The rotation of the screw 73 will drive the adjusting plate 72 to rise. The movement of the adjusting plate 72 will drive the lifting tube 3 on the outer surface of the support rod 2 to rise. The rise of the lifting tube 3 will drive the platform 4 to rise. When the platform 4 rises, it will drive the pressing plate 19 to rise and press against the pressing rod 20 on the linkage plate 21 at the top of the movable rod 22. At this time, the pressing rod 20 presses against the inclined surface on the linkage plate 21, which will drive the six toothed plates 18 to move closer to each other. The movement of the toothed plates 18 will drive the fixed plate 111 to move closer together. The fixed plate 111, following the travel rod 113, will compress the spring 114. When the toothed plate 18 moves, it engages with the toothed groove 17 at the bottom of the flip box 15. At this time, the flip box 15 can be rotated 90 degrees to unfold. Then, the items to be displayed can be placed in the placement slot 13 on the top of the connecting plate 12 and in the flip box 15. When the flip box 15 rotates, the anti-detachment rod 162 can twist the torsion spring 163. When the screw 73 rotates and drives the display stand back to its original position, the torsion spring 163 will undergo elastic deformation and drive the flip box 15 back to its original position for storage.

[0035] In summary, the adjustment and storage effects are achieved through the cooperation of the movable groove 8, movable hole 9, receiving groove 10, spring-loaded component 11, connecting plate 12, placement groove 13, motor 71, adjusting plate 72, screw 73, mating groove 14, flip box 15 and anti-detachment component 16.
