Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator packaging components, and more specifically, to a bottom shock-absorbing padding device for refrigerator packaging components. Background Technology

[0002] As a large household appliance, refrigerators rely on packaging for protection during transportation, storage, and handling after leaving the factory. The bottom shock-absorbing pad is a core component to ensure the safety of the refrigerator, playing a crucial role in buffering external impacts and isolating moisture from the bottom.

[0003] From the perspective of the refrigerator's own structure, the bottom of the refrigerator contains core electrical components such as the compressor and condenser. These components have weak shock resistance and are prone to failure when subjected to external impacts or continuous vibrations. At the same time, the refrigerant pipes and other piping systems inside the refrigerator are intricately laid out. Common road bumps and collisions during transportation and loading and unloading can cause the refrigerator to vibrate significantly, which can easily cause the pipe connections to loosen or even break, leading to serious problems such as refrigerant leakage and directly affecting the normal function of the refrigerator.

[0004] However, existing shock-absorbing pads at the bottom of refrigerator packaging generally have shortcomings: the shock-absorbing structure design is simple, relying mostly on a single layer of cushioning material, which is difficult to effectively absorb vibration energy of different intensities, and has limited protection for core components and internal pipes; the lack of a precise positioning mechanism makes it easy for the refrigerator to shift horizontally on the device after it is placed, further increasing the risk of component damage; in addition, the moisture-proof performance and structural stability of some devices are difficult to balance, and problems such as bottom dampness or device deformation occur frequently during long-term storage. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bottom shockproof padding device for refrigerator packaging, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a shock-absorbing padding device for the bottom of a refrigerator packaging component, including a base, on which a support component is provided;

[0007] The support assembly includes a pad disposed on the top of the base, and a support plate is disposed on the top of the pad;

[0008] Positioning sleeves are provided at the four outer corners of the base, and buffer posts are provided inside each positioning sleeve.

[0009] Optionally, in a possible implementation, multiple positioning sleeves are fixed on the base, and the top of each positioning sleeve extends to the bottom of the pad. A limiting plate is provided at the top of the buffer column. The limiting plate is located on the upper surface of the pad, and the bottom end of the limiting plate penetrates the pad and extends into the buffer column. A central block is embedded in the middle of the pad. A slot is opened in the middle of the central block. A docking column is engaged in the slot. The top of the docking column is fixedly set at the bottom of the tray. A limiting groove for positioning the corner of the refrigerator is opened at the top of the tray.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] Through a multi-layered buffer structure consisting of a base, buffer column, pad, and tray, the positioning sleeve and buffer column work together to absorb external impacts, while the elastic pad further weakens vibration energy. The double buffer can effectively reduce the impact of transportation bumps on the compressor and condenser at the bottom of the refrigerator, while preventing the internal refrigerant pipes from breaking due to vibration. This solves the problems of poor shock resistance and easy damage to core components in existing devices.

[0012] The limiting groove at the top of the plate can be precisely matched with the corner of the bottom of the refrigerator. Combined with the snap-fit ​​structure between the center block in the middle of the pad and the bottom docking post of the tray, the double positioning restricts the horizontal movement of the refrigerator, solving the problem of lack of positioning and easy displacement of the refrigerator in the existing device.

[0013] The base is made of high-strength material to ensure load-bearing capacity, and all components are firmly fixed by welding, threaded connection and other methods to prevent the device from deforming; the overall structure raises the bottom of the refrigerator, effectively isolating it from ground moisture, taking into account the needs of transportation and storage, and solving the problems of insufficient stability and poor moisture protection of existing devices.

[0020] 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.

[0021] This embodiment discloses a bottom shockproof padding device for refrigerator packaging, which aims to solve the problems of poor shockproof effect, insufficient protection of key components at the bottom of the refrigerator, easy breakage of internal pipes due to vibration during transportation, and easy displacement of the refrigerator on the device due to the lack of an effective positioning structure.

[0022] Specifically, the refrigerator packaging's bottom shock-absorbing padding device includes a base 1. The base 1, serving as the fundamental support component of the entire device, is made of high-strength, rigid plastic. This ensures sufficient load-bearing capacity to support the refrigerator's weight while also reducing the overall weight of the device to some extent, facilitating transportation and installation. Support components are mounted on the base 1, playing a crucial role in directly supporting the refrigerator and cushioning vibrations.

[0023] The support assembly includes a pad 2 on top of the base 1 and a tray 3 on top of the pad 2. The pad 2 is made of elastic rubber, which has good elasticity and cushioning properties, effectively absorbing some of the vibration energy generated during transportation and reducing the impact of vibration on the refrigerator. The tray 3 is made of wear-resistant and relatively rigid composite board, and its size is adapted to the contact area of ​​the bottom of a common refrigerator, ensuring that the refrigerator can be placed stably on the tray 3. A limiting groove 4 for positioning the corners of the refrigerator is opened on the top of the tray 3. Corresponding to the corner position of the bottom of the refrigerator, the shape of the limiting groove 4 matches the shape of the refrigerator corner. When the refrigerator is placed on the tray 3, the four corners of the refrigerator can be locked into the limiting groove 4, thereby effectively restricting the horizontal movement of the refrigerator and preventing the refrigerator from shifting on the device due to transportation bumps, further improving the stability of the refrigerator placement.

[0024] Positioning sleeves 5 are installed at the four outer corners of the base 1. These positioning sleeves 5 are made of metal, providing high strength and stability. Multiple positioning sleeves 5 are fixed to the base 1 by welding, with the welds rigorously sealed to prevent loosening or water ingress during use. The top of each positioning sleeve 5 extends to the bottom of the pad 2, and the positioning sleeve 5 and pad 2 are tightly fitted together. This structural design not only positions the pad 2, preventing it from shifting on the base 1, but also allows the positioning sleeves 5 to better transmit support force. A protective liner 6, made of soft silicone, is also installed on the inner wall of the positioning sleeve 5. The protective liner 6 prevents direct rigid contact between the buffer post 7 and the positioning sleeve 5, reducing wear during relative movement and further enhancing the cushioning effect.

[0025] Each positioning sleeve 5 is equipped with a buffer post 7, which is made of elastic polyurethane material and is slightly higher than the positioning sleeve 5. When the device is vibrated, the buffer post 7 can extend and retract within the positioning sleeve 5, absorbing vibration energy through its elastic deformation, thereby providing shock protection for the refrigerator. A limiting plate 8 is provided at the top of the buffer post 7. The limiting plate 8 is made of the same metal material as the positioning sleeve 5, and its diameter is larger than the inner diameter of the positioning sleeve 5. The limiting plate 8 is located on the upper surface of the pad 2, and its bottom end penetrates the pad 2 and extends into the buffer post 7. The limiting plate 8 and the buffer post 7 are fixed by a threaded connection. This connection method facilitates installation and disassembly while ensuring a secure connection. The limiting plate 8 restricts the extension and retraction range of the buffer post 7, preventing it from detaching from the positioning sleeve 5, and also evenly transmits the supporting force of the buffer post 7 to the pad 2, ensuring that the pad 2 is under balanced stress.

[0026] A central block 9, made of rigid plastic, is embedded in the center of the pad 2. It is integrally molded with the pad 2 via injection molding, ensuring a tight and stable connection. A slot 10, with an inverted trapezoidal cross-section, is formed in the center of the central block 9. This design allows the mating post 11 to be securely engaged within the slot 10, preventing it from easily slipping out. The mating post 11, made of metal, is secured within the slot 10. Its top is bolted to the bottom of the support plate 3. This bolted connection provides high strength, ensuring a firm connection between the support plate 3 and the mating post 11, thus guaranteeing the stability of the support plate 3 on the pad 2. The mating post 11 and the slot 10 are interference-fitted, further enhancing the connection stability between the support plate 3 and the pad 2, preventing displacement or wobbling of the support plate 3 on the pad 2.

[0027] The specific working principle is as follows: When using the refrigerator packaging bottom shock-absorbing pad, first place the base 1 on the bottom of the transport vehicle or on a flat surface in the storage area to ensure that the base 1 is placed stably. Then, move the refrigerator onto the pallet 3, so that the corners of the bottom of the refrigerator are engaged in the limiting grooves 4 at the top of the pallet 3. The limiting grooves 4 provide initial positioning of the refrigerator, preventing it from moving horizontally. During transportation, when encountering bumps, collisions during loading and unloading, or other impacts, the vibration energy will first be transmitted to the base 1. The buffer posts 7 inside the positioning sleeves 5 at the four outer corners of the base 1 will be affected by the vibration and absorb some of the vibration energy through their own elastic deformation. At the same time, the protective liner 6 will reduce the wear between the buffer posts 7 and the positioning sleeves 5 and further assist in absorbing vibration energy. Subsequently, the remaining vibration energy will be transmitted to the pad 2, where the elastic rubber material will absorb some of the vibration energy again, further reducing the impact of vibration on the refrigerator. The tray 3 is secured to the center block 9 in the middle of the pad 2 via the connecting post 11, ensuring the stability of the tray 3 on the pad 2 and preventing it from shifting or shaking due to vibration. This ensures the refrigerator remains stably placed on the tray 3. This multi-layered shock-absorbing structure effectively reduces the impact of vibration during transportation, protecting critical electrical components such as the compressor and condenser at the bottom of the refrigerator, as well as internal piping, from damage. It also prevents moisture from getting into the bottom of the refrigerator, providing reliable protection during transportation, storage, and handling.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
