Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator door panel storage racks, specifically a refrigerator door panel storage rack. Background Technology

[0002] In the refrigerator manufacturing industry, door panels, as exterior components, typically undergo meticulous surface treatment (such as spraying and coating), requiring extremely high levels of scratch and impact resistance. Currently, factories commonly use multi-layered storage racks in production lines and warehousing to temporarily store and transport refrigerator door panels.

[0003] However, existing storage racks have many inconveniences. When pushing or pulling the door panel into or out of the storage rack, sliding friction occurs between the bottom of the door panel and the shelf surface. This friction can easily leave scratches on the delicate door panel surface, leading to a decrease in product qualification rate and causing economic losses.

[0004] To address the aforementioned issues, we propose a refrigerator door panel storage rack. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a refrigerator door panel storage rack.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A refrigerator door panel storage rack includes a main frame. Multiple sets of shelves are arranged at equal intervals along the inner side of the main frame. Each set of shelves has a lifting plate at its inner center. Multiple sets of rollers are arranged in a rectangular array on the upper surface of each lifting plate. The lifting plates move synchronously up and down via a lifting assembly. The lifting assembly includes two lifting columns located at the midpoints of both ends of the main frame. A hydraulic cylinder is mounted on the top of each lifting column to drive its movement.

[0007] Preferably, a support plate is provided at the bottom center of each of the multiple sets of lifting plates, and a through hole is provided at the center of each end of the support plate. The two sets of lifting columns pass through the through holes at both ends of the support plate, and a limit ring is provided at the bottom of the through hole. The limit ring is fixedly installed on the lifting column.

[0008] Preferably, limit blocks are provided at the bottom of both ends of the main frame, and the end of the lifting column passes through the central hole of the limit block and extends out.

[0009] Preferably, side baffles are provided on both sides of the upper end of the shelf, and the side baffles are fixedly installed vertically on the upper surface edge of the shelf, with the lifting column located at the middle of the outer side of the side baffle.

[0010] Preferably, each of the four bottom corners of the main frame is equipped with a locking wheel.

[0011] Preferably, mounting seats are provided on both sides of the top of the main frame, and the two sets of hydraulic cylinders are respectively fixedly installed at the middle of the top of the mounting seats on both sides. The output end of the hydraulic cylinder passes through the mounting seat and is fixedly connected to the top of the lifting column.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this solution, a lifting plate with multiple sets of rollers is set in the middle of the shelf. When storing and retrieving the refrigerator door panel, the refrigerator door panel and the rollers use rolling friction, which replaces the traditional sliding friction and saves effort. At the same time, the rolling conveying by the rollers also effectively avoids scratches and wear on the delicate surface of the refrigerator door panel during the pushing and pulling process, effectively protecting the outer surface of the refrigerator door panel and ensuring product quality and yield.

[0015] The technical solution in this application embodiment addresses the problems described in the background technology. The overall concept is as follows: This utility model features high space utilization and flexible movement. The storage rack maintains a multi-layer storage structure, resulting in high space utilization. Simultaneously, by installing locking wheels 13 at the bottom of the main frame 1, the entire storage rack can be easily moved and positioned according to production rhythm or warehousing needs, offering excellent flexibility. Furthermore, by setting a lifting plate 3 with multiple sets of rollers 4 in the middle of the shelf 2, rolling friction occurs between the refrigerator door panel and the rollers 4 when storing or retrieving the refrigerator door panel, replacing traditional sliding friction. This effectively avoids scratches and wear on the delicate surface of the refrigerator door panel during pushing and pulling, effectively protecting the outer surface of the refrigerator door panel and ensuring product quality and yield.

[0016] Example: Refer to Figure 1 - Figure 4 As shown, a refrigerator door panel storage rack in this embodiment includes a main frame 1. Multiple sets of shelves 2 are arranged in the middle of the inner side of the main frame 1. The shelves 2 are equidistantly distributed vertically. A lifting plate 3 is provided in the middle of the inner side of each shelf 2. Multiple sets of rollers 4 are provided on the upper surface of each lifting plate 3. The rollers 4 are arranged in a rectangular array on the upper surface of the lifting plate 3. The lifting plates 3 are driven to move synchronously up and down by a lifting assembly. When taking out or placing the refrigerator door panel, the rolling action of the rollers 4 saves effort and avoids friction between the refrigerator door panel and the shelves 2, preventing scratches.

[0017] The lifting assembly includes two sets of lifting columns 7, which are located at the middle of both ends of the main frame 1. A hydraulic cylinder 9 is installed at the top of each lifting column 7, and the hydraulic cylinder 9 is used to drive the lifting column 7 to move up and down. Additionally, a support plate 5 is installed at the middle of the bottom end of each of the multiple lifting plates 3. Through holes 6 are provided at the middle of both ends of each support plate 5. The two sets of lifting columns 7 pass through the through holes 6 at both ends of the support plate 5. A limit ring 8 is installed at the bottom of the through hole 6, and the limit ring 8 is fixedly installed on the lifting column 7.

[0018] The lifting column 7 passes through the through holes 6 of each layer of support plate 5 and is equipped with a limit ring 8 to ensure that the multi-layer lifting plate 3 can remain horizontal and move synchronously during the lifting process, running smoothly without jamming or tilting, thus ensuring the reliability of storage and lifting. When the lifting column 7 is rising, under the action of the limit ring 8, it can synchronously drive the support plate 5 to rise, thereby lifting the lifting plate 3. Conversely, when descending, without the limit ring 8, the support plate 5 and the lifting plate 3 will descend together under their own weight. During the descent, the lifting plate 3 does not need to completely detach from the shelf 2. It is only necessary for the top surface of the roller 4 to descend to the same level as the top surface of the shelf 2, thus avoiding the situation where the lifting plate 3 is difficult to reinsert into the shelf 2 after it has completely detached.

[0019] In some examples, limit blocks 12 are provided at the bottom of both ends of the main frame 1. The end of the lifting column 7 passes through and extends out of the center hole of the limit block 12. The limit block 12 mainly plays a role in limiting the lifting of the lifting column 7, enhancing the stability of the lifting column 7, and preventing deviation and tilting.

[0020] In some examples, side baffles 11 are provided on both sides of the upper end of the shelf 2. The side baffles 11 are fixedly installed vertically on the upper surface edge of the shelf 2, and the lifting column 7 is located in the middle of the outer side of the side baffle 11.

[0021] In some examples, mounting seats 10 are provided on both sides of the top of the main frame 1, and two sets of hydraulic cylinders 9 are fixedly installed at the middle of the top of the mounting seats 10 on both sides. The output end of the hydraulic cylinder 9 passes through the mounting seat 10 and is fixedly connected to the top of the lifting column 7.

[0022] In some examples, the four bottom corners of the main frame 1 are equipped with locking casters 13 to facilitate the movement and adjustment of the position of the main frame 1. The main frame 1 needs to be placed in a horizontal position to prevent the refrigerator door panel from sliding off the shelf 2 when tilted.

[0023] In some examples, the hydraulic cylinder 9 of this utility model can be raised and lowered by a button, which can be installed on the front of the main frame 1. This control module uses existing technology and will not be described in detail.

[0024] The working principle of this utility model is as follows: During use, the staff first need to move the main frame 1 to the designated location using the casters 13 for horizontal and stable placement, and then lock the casters 13.

[0025] When the refrigerator door panel needs to be placed, the hydraulic cylinder 9 is first activated to drive the lifting column 7 to rise. Under the action of the limiting ring 8, the support plate 5 and the lifting plate 3 are raised, causing multiple sets of rollers 4 to protrude from the upper surface of the shelf 2. At this time, the refrigerator door panel is placed directly on the multiple sets of rollers 4. With the help of the rolling of the rollers 4, the refrigerator door panel can be easily pushed inward, which saves effort. At the same time, it also reduces the friction between the refrigerator door panel and the shelf 2, thereby effectively avoiding scratches and damage to the refrigerator door panel caused by friction with the shelf 2.

[0026] After all the refrigerator door panels are placed, the hydraulic cylinder 9 pushes the lifting column 7 down. At this time, the limit ring 8 is no longer restricted, and the lifting plate 3 will follow the downward due to its own weight, so that the roller 4 will fall down to the same level as the shelf 2. At this time, the multiple sets of rollers 4 and the shelf 2 together support the refrigerator door panels, thereby enhancing the stability of the placement.

[0027] Conversely, when it is necessary to remove the refrigerator door panel, the hydraulic cylinder 9 drives the lifting column 7 to rise, and the lifting plate 3 rises to lift the refrigerator door panel. At this time, the refrigerator door panel can be pulled. During the pulling, the rollers 4 roll to achieve rolling transport of the refrigerator door panel, which saves effort and also minimizes the friction between the refrigerator door panel and the shelf 2.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
