Description

Technical Field

[0001] This utility model relates to the field of lifting display rack technology, specifically to an internally liftable display rack structure. Background Technology

[0002] In scenarios such as exhibitions, store displays, and museum exhibits, lifting display racks have become the mainstream display equipment due to their height-adjustable advantage. Most existing lifting display racks adopt an open frame structure, with the internal lifting mechanism and exhibits directly exposed to the air. Only a few products are equipped with simple shielding components, lacking a dedicated storage and protection structure.

[0003] Existing display rack structures have two main drawbacks: first, they lack effective storage, protection, and dust prevention structures, leading to wear and dust accumulation on exhibits due to prolonged exposure, which affects the display effect and lifespan; second, open or simple sealed structures cannot meet the protection requirements of delicate exhibits, and the manual opening of protective components is disconnected from the lifting operation, making the process cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an internally adjustable display rack structure to solve the problems mentioned in the background section. This utility model features a novel structure, forming a complete dustproof protection system by incorporating a sealed storage shell and a linked opening and closing protective cover. This effectively blocks dust erosion, prevents wear and dust accumulation on exhibits and lifting components, and improves display effectiveness and lifespan. The drive mechanism and linkage mechanism work in tandem, enabling the cover opening and closing and display rack lifting to proceed synchronously, eliminating the need for manual operation and simplifying the process. Simultaneously, it enhances structural compactness and reduces space occupancy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an internally adjustable display rack structure, comprising a storage shell, a rectangular frame fixedly connected to the upper side of the storage shell, two rotating shafts rotatably fitted to the inner wall of the rectangular frame, protective covers fixedly connected to the two rotating shafts inside the rectangular frame, a fixing plate fixedly connected to the inside of the storage shell, multiple telescopic rods mounted on the upper side of the fixing plate, a placement plate fixedly connected to the movable ends of the multiple telescopic rods, a sliding groove provided on the upper side of the fixing plate, an I-shaped slide block slidably fitted to the inner wall of the sliding groove, a connecting rod plate provided between the upper end of the I-shaped slide block and the lower side of the placement plate, a driving mechanism provided inside the storage shell, and linkage mechanisms cooperating with the rotating shafts provided on both sides of the inner wall of the storage shell.

[0006] Furthermore, the two protective covers are engaged at their closest ends, and the two ends of the connecting rod plate are respectively engaged with the placement plate and the I-shaped slide. Both protective covers are in contact with the inner wall of the rectangular frame.

[0007] Furthermore, the driving mechanism includes a threaded rod rotatably fitted on the inner wall of the storage shell, a driving plate threadedly fitted on the threaded rod, a pressing plate fixedly connected to the upper side of the driving plate, guide plates fixedly connected to both sides of the driving plate, an L-shaped guide groove opened on one side of each of the two guide plates, and a driving motor installed on one side of the storage shell.

[0008] Furthermore, the output end of the drive motor extends into the interior of the storage shell and is fixedly connected to one end of the threaded rod. The upper end of the extrusion plate cooperates with the lower end of the I-shaped slide block. The fixing plate is located between the two guide plates. Two slide rods are fixedly connected to the inner wall of the storage shell. The drive plate is slidably fitted on the two slide rods.

[0009] Furthermore, the linkage mechanism includes lifting plates disposed on both sides of the inner wall of the storage shell. Each of the two lifting plates has a limit groove on one side. Limit rods are fixedly connected to both sides of the inner wall of the storage shell. A horizontal plate is fixedly connected to the upper end of the two lifting plates. A strip groove is provided on one side of the horizontal plate. L-shaped connecting rods are fixedly connected to both ends of the two rotating shafts. A sliding rod is fixedly connected to the lower end of the two L-shaped connecting rods near the horizontal plate. A pressing rod is fixedly connected to one side of the lifting plate.

[0010] Furthermore, the limiting rod is slidably fitted on the inner wall of the limiting groove, the sliding rod is slidably fitted on the inner wall of the strip groove, and the extrusion rod is slidably fitted on the inner wall of the L-shaped guide groove.

[0011] Furthermore, two support plates are symmetrically fixedly connected to the upper side of the placement plate. Each of the two support plates has a screw threaded onto its opposite side. Each of the two screws has a clamping plate rotatably fitted onto its closest end. Each of the two support plates has a limit guide rod slidably fitted onto one side. Multiple limit guide rods are respectively fixedly connected to one side of the corresponding clamping plate.

[0012] Furthermore, an observation window is provided on one side of the storage shell.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model forms a complete dust protection system by setting a sealed storage shell and a protective cover that opens and closes in conjunction with the structure. This effectively blocks dust erosion, prevents wear and dust accumulation on exhibits and lifting components, and improves the display effect and service life. The drive mechanism and the linkage mechanism work together to realize the opening and closing of the cover and the lifting of the display stand simultaneously. No manual operation is required, which improves the problem of cumbersome operation process. At the same time, it improves the compactness of the structure and reduces space occupation.

[0015] 2. This utility model, by setting a clamping plate driven by a lead screw and a limiting guide rod, can flexibly adapt to exhibits of different sizes and fix them firmly, avoiding the exhibits from shaking during the lifting process, further improving the stability of the display and enhancing the flexibility of use.

[0024] Please refer to Figures 1 to 6This utility model provides a technical solution: an internally adjustable display rack structure, including a storage shell 1, a rectangular frame 2 fixedly connected to the upper side of the storage shell 1, two rotating shafts 3 rotatably fitted on the inner wall of the rectangular frame 2, protective cover plates 4 fixedly connected to the two rotating shafts 3 inside the rectangular frame 2, a fixing plate 5 fixedly connected inside the storage shell 1, multiple telescopic rods 6 installed on the upper side of the fixing plate 5, a placement plate 7 fixedly connected to the movable end of the multiple telescopic rods 6, a sliding groove 8 opened on the upper side of the fixing plate 5, an I-shaped slide block 9 slidably fitted on the inner wall of the sliding groove 8, a connecting rod plate 10 provided between the upper end of the I-shaped slide block 9 and the lower side of the placement plate 7, a driving mechanism 11 provided inside the storage shell 1, and linkage mechanisms 12 that cooperate with the rotating shafts 3 on both sides of the inner wall of the storage shell 1. The two protective cover plates 4 are fitted together at their closest ends, and the two ends of the connecting rod plate 10 are rotatably fitted with the placement plate 7 and the I-shaped slide block 9 respectively, with both protective cover plates 4 in contact with the inner wall of the rectangular frame 2. Two support plates 14 are symmetrically fixedly connected to the upper side of the placement plate 7. Each support plate 14 has a threaded screw 15 on its opposite side. A clamping plate 16 is rotatably fitted to the closest end of each screw 15. Limiting guide rods 17 are slidably fitted to one side of each support plate 14. Multiple limiting guide rods 17 are respectively fixedly connected to one side of the corresponding clamping plate 16. An observation window 18 is provided on one side of the storage shell 1. The support plate 14 on the placement plate 7 works in conjunction with the lead screw 15. Rotating the lead screw 15 drives the clamping plate 16 to move. The limit guide rod 17 ensures stable clamping, adapts to exhibits of different sizes and fixes them firmly, preventing exhibits from shaking or shifting during lifting and improving display stability. The observation window 18 of the storage shell 1 allows real-time viewing of the internal status, balancing protection and convenient observation needs. The protective cover 4 fits snugly and seals against the rectangular frame 2, forming a closed space when stored, effectively blocking dust and protecting exhibits and lifting components. The drive mechanism 11 and the linkage mechanism 12 work together to achieve simultaneous "cover opening and closing - display stand lifting" without manual operation, simplifying the process. At the same time, the telescopic rod 6 and the guide design of the slide 8 ensure no deviation during lifting and stable load bearing.

[0025] In this embodiment, the driving mechanism 11 includes a threaded rod 111 rotatably fitted to the inner wall of the housing 1. A driving plate 112 is threaded onto the threaded rod 111. A pressing plate 113 is fixedly connected to the upper side of the driving plate 112. Guide plates 114 are fixedly connected to both sides of the driving plate 112. An L-shaped guide groove 115 is provided on one side of each of the two guide plates 114. A driving motor 116 is installed on one side of the housing 1. The output end of the driving motor 116 extends into the interior of the housing 1 and is fixedly connected to one end of the threaded rod 111. The upper end of the pressing plate 113 engages with the lower end of the I-shaped slide block 9. A fixing plate 5 is located between the two guide plates 114. Two sliding rods 13 are fixedly connected to the inner wall of the housing 1, and the driving plate 112 is slidably fitted onto the two sliding rods 13. The drive motor 116 starts and drives the threaded rod 111 to rotate. The drive plate 112 slides along the slide rod 13. The pressing plate 113 pushes the I-shaped slide block 9 to move along the slide groove 8. The connecting rod plate 10 lifts the placement plate 7. The telescopic rod 6 extends and retracts synchronously to guide the exhibit, so as to realize the smooth lifting and lowering of the exhibit.

[0026] In this embodiment, the linkage mechanism 12 includes lifting plates 121 disposed on both sides of the inner wall of the storage shell 1. Each lifting plate 121 has a limiting groove 122 on one side. Limiting rods 123 are fixedly connected to both sides of the inner wall of the storage shell 1. A horizontal plate 124 is fixedly connected to the upper end of each lifting plate 121. A strip groove 125 is formed on one side of the horizontal plate 124. L-shaped connecting rods 126 are fixedly connected to both ends of two rotating shafts 3. Sliding rods 127 are fixedly connected to the lower ends of the two L-shaped connecting rods 126 near the horizontal plate 124. A pressing rod 128 is fixedly connected to one side of each lifting plate 121. The limiting rod 123 slides within the inner wall of the limiting groove 122, the sliding rod 127 slides within the inner wall of the strip groove 125, and the pressing rod 128 slides within the inner wall of the L-shaped guide groove 115. The drive plate 112 drives the guide plate 114 to move. The L-shaped guide groove 115 drives the lifting plate 121 to rise and fall along the limit rod 123 through the extrusion rod 128. The horizontal plate 124 drives the L-shaped connecting rod 126 and the rotating shaft 3 to rotate through the strip groove 125 and the sliding rod 127, so that the protective cover 4 opens and closes automatically, with smooth linkage and dust protection.

[0027] When the device is in use, the drive motor 116 starts and drives the threaded rod 111 to rotate. The drive plate 112 slides laterally along the slide rod 13. On the one hand, the extrusion plate 113 pushes the I-shaped slide block 9 to move in the slide groove 8, and lifts the placement plate 7 through the connecting rod plate 10. The telescopic rod 6 extends and retracts to assist in the guidance, so that the exhibit can be raised. On the other hand, the L-shaped guide groove 115 of the guide plate 114 drives the extrusion rod 128, so that the lifting plate 121 rises and falls vertically along the limit rod 123. The horizontal plate 124 drives the L-shaped connecting rod 126 through the strip groove 125 and the sliding rod 127, which drives the rotating shaft 3 to rotate, so that the protective cover plate 4 opens automatically.

[0028] The exhibit is fixed by the screw 15 driving the clamping plate 16, and the limit guide rod 17 ensures the stability of the clamping. When storing, the drive motor 116 reverses, the drive plate 112 resets, the placement plate 7 descends, and the protective cover 4 closes simultaneously to form a sealed space to prevent dust and moisture. The observation window 18 can be used to view the internal status in real time. The whole system realizes automatic linkage, stable load-bearing and effective protection.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
