Description

Technical Field

[0001] This utility model relates to the field of logistics and warehousing equipment technology, and in particular to an adjustable shelf. Background Technology

[0002] Logistics racks are racks used in logistics turnover centers. They are generally divided into warehouse racks and drive-in racks. In the field of logistics warehousing equipment technology, traditional racks usually adopt a fixed structure and have a single load-bearing surface shape.

[0003] In existing technology, operators place goods directly on the fixed flat surface of the shelf, regardless of whether the goods are square, cuboid, or other regular shapes; all are stored in the same way. If cylindrical goods need to be stored, they can only be placed horizontally or vertically on the flat surface, and simple supports such as wooden boards or foam are added around the goods to prevent them from rolling or tipping over, thus maintaining the stability of the goods.

[0004] Because the load-bearing surface is fixed, it is difficult to provide good support and fixation for irregularly shaped or special-shaped goods, such as cylindrical goods. These goods are prone to shifting and tipping, posing safety hazards. The supports added to prevent rolling occupy extra storage space, reducing space utilization. Storing goods of different shapes requires frequent adjustment of supports, which is cumbersome and increases labor and time costs. Therefore, an adjustable shelving system is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable shelf, which aims to improve the problems of existing shelves having a single load-bearing surface, poor adaptability, easy displacement of goods with special shapes, and low space utilization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable shelf, including a base, a frame fixedly connected to the top of the base, a crossbar fixedly connected to the inner wall of the frame, and a switching component provided on the crossbar;

[0007] The switching assembly includes a movable plate located inside the crossbeam. A hinge plate is hinged to the side of the movable plate via a pin. A groove is provided on the inner wall of the crossbeam. Slider blocks are fixedly connected to the front and back of the movable plate, respectively. A rotating rod is rotatably connected to the inner wall of the groove via a bearing. The surface of the rotating rod is provided with opposite threads. Slider blocks are threaded onto the opposite threads on the surface of the rotating rod. The front of the slider is fixedly connected to the back of the movable plate. A drainage assembly is provided on the frame.

[0008] As a further description of the above technical solution: the drainage component includes a diversion plate, which is fixedly connected to both sides of the frame, and the surface of the hinge plate is provided with drainage holes.

[0009] As a further description of the above technical solution: a triangular baffle is fixedly connected to the bottom of the cross frame, and the diversion plate is fixedly connected to the bottom of the triangular baffle.

[0010] As a further description of the above technical solution: the diversion plate is inclined, the surface of the diversion plate is provided with diversion grooves, and the diversion plates are longitudinally distributed above the frame.

[0011] As a further description of the above technical solution: water collection shells are fixedly connected to both sides of the base, the top of the water collection shells is open, and the water collection shells are configured to cooperate with the guide plate.

[0012] As a further description of the above technical solution: both the slider and the groove are "T" shaped, and the slider is slidably connected to the inner wall of the groove.

[0013] As a further description of the above technical solution: the inner wall of the cross frame is provided with a limiting groove, the movable front is fixedly connected to a limiting block, the limiting block is slidably connected to the inner wall of the limiting groove, and both the limiting groove and the limiting block are "T" shaped.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3This utility model provides an embodiment of an adjustable shelf, including a base 1. The base 1 provides stable support for the entire shelf and serves as the foundation for the installation of the frame 2 and other components. The frame 2 is fixedly connected to the top, forming the main framework of the shelf and providing installation positions for components such as crossbars 4. Crossbars 4 are fixedly connected to the inner wall of the frame 2, serving as the mounting carrier for switching components, carrying goods, and participating in shelf shape adjustment. Switching components are provided on the crossbars 4, changing the shape of the shelf's load-bearing surface to adapt to different goods placement needs. The switching components include a movable plate 8. The movable plate 8 is located inside the cross frame 4. The side of the movable plate 8 is hinged to a hinge plate 5 by a pin. The hinge plate 5 can rotate around the pin and fold or unfold under the drive of the movable plate 8 to form a bearing surface of different shapes. The inner wall of the cross frame 4 is provided with a slide groove 11. The slide groove 11 provides a sliding track for the slider 10. Its "T"-shaped structure prevents the slider 10 from falling off. The front and back of the movable plate 8 are respectively fixedly connected to the slider 10. The slider 10 is slidably connected to the inner wall of the slide groove 11. The slider 10 slides in the slide groove 11 to realize the smooth movement of the movable plate 8. Both the slider 10 and the slide groove 11 are "T"-shaped.

[0027] Reference Figure 3 , Figure 4 The inner wall of the slide 11 is rotatably connected to a rotating rod 9 via a bearing. The rotating rod 9 serves as a power transmission component, driving the slider 10 to move through rotation. A knob is fixedly connected to the end of the rotating rod 9, allowing the operator to manually rotate the rod 9 to control the switching component. The surface of the rotating rod 9 has opposing threads, which allow the two sliders 10 to move closer or further apart during rotation. Slider 10s are threaded onto the opposing threads of the rotating rod 9, and the sliders 10 engage with the rotating rod 9 to rotate... The rotation of rod 9 is converted into linear movement. The front of slider 10 is fixedly connected to the back of moving plate 8. A limit groove 13 is opened on the inner wall of crossbar 4. The limit groove 13 provides guidance and limit for limit block 14 to ensure the stability of moving plate 8. Limit block 14 is fixedly connected to the front of moving plate 8. Limit block 14 is slidably connected to the inner wall of limit groove 13. Limit block 14 slides in limit groove 13 to further limit the moving direction of moving plate 8 and prevent it from deviating. Limit groove 13 and limit block 14 are both "T" shaped.

[0028] Reference Figure 1 , Figure 2 , Figure 4The frame 2 is equipped with a drainage assembly for collecting leaked liquid from goods and maintaining a clean storage environment. The drainage assembly includes a diversion plate 6, which is fixedly connected to both sides of the frame 2. The diversion plate 6 is inclined and has a diversion groove 12 to guide the liquid flow to the collection shell 3. The surface of the hinge plate 5 has drainage holes 7, which allow leaked liquid to enter the diversion plate 6 through the hinge plate 5. The bottom of the crossbar 4 is fixedly connected to a triangular baffle 15, which fits snugly. The hinge plate 5, after being folded into a "V" shape, limits the front and rear movement of the goods on the hinge plate 5 to prevent them from falling. The diversion plate 6 is fixedly connected to the bottom of the triangular baffle 15. The diversion plate 6 is inclined and has a diversion groove 12 on its surface. The diversion plates 6 are arranged longitudinally above the frame 2. Water collection shells 3 are fixedly connected to both sides of the base 1. The top of the water collection shell 3 is open to collect the liquid flowing down from the diversion groove 12 of the diversion plate 6. The water collection shell 3 is configured to cooperate with the diversion plate.

[0029] Reference Figure 1 Each layer of horizontal frame 4 has two sets of hinge plates 5 and movable plates 8. Each set has two hinge plates 5 and two movable plates 8. The two hinge plates 5 are in a "V" shape. The adjacent sides of the hinge plates 5 are hinged by a pin. The two sets of hinge plates 5 and movable plates 8 work together to enhance the stability and load-bearing capacity of the rack for cylindrical goods.

[0030] Working principle: When cylindrical goods need to be placed, the operator turns the knob, which drives the rotating rod 9 to rotate. Because the surface of the rotating rod 9 has opposite threads, and its two ends are respectively threaded with sliders 10, when the rotating rod 9 rotates, the two sliders 10 slide closer to each other in the sliding groove 11 along opposite thread directions. Since the sliders 10 are fixedly connected to the front and back of the moving plate 8 respectively, and both the sliders 10 and the sliding groove 11 are "T" shaped, this structural design ensures that the sliders 10 can only slide within the sliding groove 11, preventing the sliders 10 from detaching from the sliding groove 11. At the same time, the limiting block 14 fixedly connected to the front of the moving plate 8 slides within the limiting groove 13. The limiting groove 13 and the limiting block 14 are also "T" shaped. The cooperation between the limiting block 14 and the limiting groove 13 further restricts the movement direction of the moving plate 8, ensuring that the moving plate 8 moves smoothly and preventing it from deviating or shaking during movement.

[0031] As the two sliders 10 approach each other, the two movable plates 8 move synchronously with the sliders 10. The hinge plate 5, hinged to the movable plate 8 via a pin, gradually folds into a "V" shape due to the downward curvature of the movable plate 8, thereby changing the shape of the shelf's load-bearing surface to accommodate cylindrical goods. Each horizontal shelf 4 has two sets of hinge plates 5 and movable plates 8, with two plates in each set. The two hinge plates 5 are in a "V" shape and are hinged to adjacent sides via a pin. This design allows the shelf to stably support cylindrical goods. Furthermore, a triangular baffle 15 fixedly connected to the bottom of the horizontal shelf 4 matches the "V" shape of the folded hinge plate 5, limiting the forward and backward movement of the "V" shaped hinge plate 5 and effectively preventing goods from falling through the gaps between the hinge plates 5, thus enhancing the safety and stability of the shelf when placing cylindrical goods.

[0032] When a cylindrical item contains liquid and leaks, the liquid first passes through the drain hole 7 on the surface of the hinge plate 5. Since the diversion plates 6 fixedly connected to both sides of the frame 2 are inclined and have diversion grooves 12 on their surfaces, the liquid flows into the diversion grooves 12 along the inclined angle of the diversion plates 6 after passing through the drain hole 7. Then, following the guide of the diversion grooves 12, it finally flows into the water collection shells 3 fixedly connected to both sides of the base 1. The top opening of the water collection shells 3 is set and cooperates with the diversion plates 6 to complete the liquid collection work, preventing the liquid from dripping onto the ground or other goods, and maintaining the cleanliness of the storage environment and the safety of the goods.

[0033] In actual use, first determine whether the shelf configuration needs to be adjusted based on the shape of the goods to be placed. If the goods are cylindrical, turn the knob to adjust the hinge plate 5 into a "V" shape according to the working principle of the switching components described above; if the goods are of other shapes, turn the knob in the opposite direction to move the two sliders 10 away from each other, causing the moving plate 8 and the hinge plate 5 to unfold and form a flat bearing surface to accommodate the placement of goods of different shapes.

[0034] During cargo placement, the cargo is placed smoothly on the adjusted hinge plate 5. For cylindrical cargo, ensure it is positioned in the middle of the "V"-shaped hinge plate 5, using the triangular baffle 15 for restraint. If a liquid leak occurs during cargo storage, the liquid will automatically flow into the water collection tank 3 through the drainage assembly. Once the water collection tank 3 is full, the operator can remove it from the base 1, properly dispose of the liquid, and then reinstall the water collection tank 3 back onto the base 1 to continue collecting liquid.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
