Description

Technical Field

[0001] This utility model relates to a storage shelf, and more specifically, to a storage shelf for wooden vases. Background Technology

[0002] Wooden vase display shelves, in short, are shelving systems made primarily of wood, specifically designed for storing and displaying wooden vases. They combine the natural beauty and practicality of wood, providing a stable, attractive, and easy-to-manage display platform for wooden vases.

[0003] When using existing wooden vase display shelves, if the wooden vase is placed on the top shelf, people need to use a ladder or stepping stones to reach it because of the height of the top shelf. Using ladders or stepping stones increases the instability of operation, which can easily lead to people falling or falling and causing physical injury. In addition, it requires frequent movement of ladders or stepping stones to reach vases in different positions, which increases the complexity of operation.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shelf for placing wooden vases, which aims to solve the technical problem that wooden vases are inconvenient to pick up, making them easy to fall and reduce safety.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wooden vase shelf, including uprights, two uprights are provided, and three placement plates are provided on the opposite sides of the two uprights. The middle placement plate and the lower placement plate are fixedly connected to the uprights, and the upper placement plate is movably connected to the uprights. A sliding groove is provided on the opposite sides of the two uprights. A driving component is provided in the left sliding groove. An adjusting plate is threadedly connected to the upper part of the outer surface of the driving component. The adjusting plate is fixedly connected to the bottom of the upper placement plate.

[0007] The present invention is further configured such that: the driving assembly includes a servo motor, a first lead screw is fixedly installed at the output end of the servo motor, an adjusting plate is movably threadedly connected to the first lead screw, a fixing block is fixedly installed on the upper side of the servo motor, the fixing block is fixedly connected in the left slide groove, a synchronous pulley is fixedly installed on the upper part of the first lead screw, a synchronous belt is movably connected to the outer surface of the synchronous pulley, and a second lead screw is fixedly installed on the right side of the inner cavity of the synchronous belt through a right synchronous pulley, the second lead screw moving inside the right slide groove.

[0008] The present invention is further configured such that two pads are fixedly installed at the lower end of the support frame.

[0009] The present invention is further configured such that a stabilizing plate is fixedly installed on the lower part of the opposite surfaces of the two uprights, and the stabilizing plate is located below the lower placement plate.

[0010] The present invention is further configured such that: a plurality of placement circular grooves are provided at the upper end of the placement plate, and a baffle is fixedly installed on both the front and rear sides of the upper end of the placement plate.

[0011] In summary, this utility model has the following beneficial effects:

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A wooden vase for display on a shelf, such as Figures 1 to 2 As shown, the device includes a support frame 1, of which there are two. The two support frames 1 have three placement plates 2 on their opposite sides. The middle placement plate 2 and the lower placement plate 2 are fixedly connected to the support frame 1, and the upper placement plate 2 is movably connected to the support frame 1. Each of the two support frames 1 has a sliding groove 3 on its opposite side. A drive assembly 4 is installed in the left sliding groove 3. An adjustment plate 5 is threadedly connected to the upper part of the outer surface of the drive assembly 4. The adjustment plate 5 is fixedly connected to the bottom of the upper placement plate 2.

[0021] Two pads 7 are fixedly installed at the lower end of the upright frame 1, which provide support and stability to the upright frame 1.

[0022] A stabilizing plate 8 is fixedly installed on the lower part of the opposite sides of the uprights 1. The stabilizing plate 8 is located below the lower plate 2. As a key component connecting the two uprights 1, the stabilizing plate 8 can significantly enhance the stability of the entire structure. By tightly connecting the two uprights 1 together, it forms a more stable overall frame, effectively resisting external loads and deformation.

[0023] The upper end of the placement plate 2 has several circular grooves 9. A baffle 10 is fixedly installed on both the front and rear sides of the upper end of the placement plate 2. The design of the circular grooves 9 provides a precise positioning space for the wooden vase, ensuring that the vase can be placed stably on the shelf and is not easy to shake or tip over. The baffle 10 can effectively prevent the wooden vase from tipping over on the placement plate 2 due to external forces (such as collisions, vibrations or touches when customers select), ensuring the stability of the vase.

[0024] like Figure 2As shown, the drive assembly 4 includes a servo motor 41. A first lead screw 42 is fixedly mounted on the output end of the servo motor 41. An adjusting plate 5 is movably threaded onto the first lead screw 42. A fixing block 43 is fixedly mounted on the upper side of the servo motor 41 and is fixedly connected to the left slide groove 3. A synchronous pulley 44 is fixedly mounted on the upper part of the first lead screw 42. A synchronous belt 45 is movably connected to the outer surface of the synchronous pulley 44. A second lead screw 46 is fixedly mounted on the right side of the inner cavity of the synchronous belt 45 through the right synchronous pulley 44. The second lead screw 46 moves inside the right slide groove 3. To ensure the servo motor... To facilitate power supply to the servo motor 41 and enhance the overall aesthetics and mobility of the shelf, a removable battery box is installed on the side near the servo motor 41. The battery box contains batteries, which are connected to the servo motor 41 via power cables. This design not only increases usability but also avoids the inconvenience of excessively long or tangled power cords. The synchronous belt 45 is positioned far from the upper shelf 2 to ensure that the wooden vases will not collide with it, effectively guaranteeing its normal transmission and preventing transmission failures or damage caused by external impacts. By setting a first lead screw 42 and a second lead screw 46, and utilizing a synchronous pulley 44 and a synchronous belt 45 to achieve dual-side linkage transmission, the upper placement plate 2 is ensured to move smoothly, synchronously, without tilting or jamming during lifting. Driving force is provided simultaneously from both ends, enabling the upper placement plate 2 to lift synchronously from both ends. The weight of the vase and placement plate 2 is evenly distributed across the transmission systems on both sides, significantly reducing stress concentration at single points and improving the overall structural rigidity and stability. The first lead screw 42 and the second lead screw 46 are trapezoidal lead screws with self-locking characteristics. The threads of the trapezoidal lead screws have a trapezoidal cross-section, and the thread helix angle (…). The angle between the helix and the plane perpendicular to the axis is usually designed to be small (generally less than 4°). When the nut (here, the adjusting plate 5) is fitted onto the lead screw, its movement depends on the external driving force (the torque of the servo motor 41) to overcome the static friction between the threads. Once the external driving force stops (the servo motor 41 stops), since the friction angle of the thread helix is ​​greater than the thread helix angle, the component of gravity along the helix direction is insufficient to overcome the static friction between the thread pairs. Therefore, even if the total weight of the upper placement plate 2 and the vase is large, the system can still remain stationary and will not experience reverse drive or free fall.

[0025] Working principle: The upper shelf 2 is located at the highest position of the shelf, maintaining a certain distance from the middle shelf 2 to form a normal display layout;

[0026] When the wooden vase needs to be placed on the upper placement plate 2, the servo motor 41 is started. The servo motor 41 drives the first lead screw 42 to rotate. Since the adjusting plate 5 is threadedly connected to the first lead screw 42 and is limited by the slide groove 3, the adjusting plate 5 generates a downward spiral motion on the first lead screw 42. At the same time, the synchronous wheel 44 at the upper end of the first lead screw 42 drives the second synchronous wheel 44 on the right side to rotate through the synchronous belt 45, thereby driving the second lead screw 46 to rotate synchronously. The adjusting plate 5 is fixedly connected to the bottom of the upper placement plate 2. Therefore, under the synchronous drive of the left and right lead screws, the upper placement plate 2 descends smoothly along the slide grooves on both sides until it drops to a height close to that of the middle placement plate 2, making it convenient for operators to safely place the vase on the ground.

[0027] The operator places the wooden vase with its bottom aligned with the placement groove 9 on the upper placement plate 2. The front and rear baffles 10 prevent the vase from sliding or tipping over. The entire process does not require the use of ladders or stepping tools, and the operator's feet remain firmly on the ground, greatly improving the safety and convenience of the operation.

[0028] After the vases are placed, the servo motor 41 is started in reverse, driving the lead screw to rotate in the opposite direction. The adjusting plate 5 moves upward, causing the upper placement plate 2 to rise back to its original height along the slide 3. At this time, the shelf returns to a complete three-layer display state, and the vases are safely and stably displayed on the top layer. After the upper layer vases are placed, other vases can be placed on the fixed placement plates 2 of the middle and lower layers in turn to complete the display.

[0029] In summary, the design of the liftable upper placement plate 2 allows users to safely place vases at heights from the ground without climbing ladders or using stepping stones, fundamentally avoiding accidents such as falls due to imbalance and ensuring the personal safety of operators. The height of the top layer can be automatically adjusted simply by activating the servo motor 41, making the operation simple, time-saving, and labor-saving.

[0030] It is worth noting that the servo motor 41 disclosed in the above embodiments is specifically a Panasonic MINAS A6 series, and the external control switch group and external power supply control the operation of the servo motor 41 adopt the methods commonly used in the prior art.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
