Description

Technical Field

[0001] This utility model relates to the field of refrigerator door support technology, specifically a reinforcement structure for refrigerator door support. Background Technology

[0002] The refrigerator door bracket is a key component in the refrigerator door structure. It is mainly used to support the weight of the door, fix accessories on the door (such as storage shelves, decorative panels, sealing strips, etc.), and ensure the stability and durability of the door during opening and closing. The refrigerator door bracket is a frame structure installed inside the refrigerator door. It is usually made of metal (such as stainless steel, aluminum alloy) or composite materials (such as plastic, fiberglass) to support the overall structure of the door and prevent the door from deforming or sagging.

[0003] However, existing unreinforced supports are usually made of a single material (such as ordinary plastic or thin metal), which has poor impact and fatigue resistance. When the door is opened and closed frequently, the support may break or loosen due to vibration or external impact. In humid or corrosive environments (such as kitchens), metal supports are prone to rust, and plastic supports are prone to aging and embrittlement, requiring frequent replacement of the supports and increasing maintenance costs. To address these issues, we propose a reinforced structure for refrigerator door supports. Summary of the Invention

[0004] The purpose of this utility model is to provide a reinforcement structure for a refrigerator door support to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforcement structure for a refrigerator door bracket, comprising a bracket body, a reinforcement plate fixedly connected to the lower left side of the bracket body, a reinforcement frame engaged on the right side of the bracket body, a reinforcement rod inserted into the bracket body, and a nut sleeved on the lower end of the reinforcement rod.

[0006] Preferably, the support body includes a reinforcing layer disposed on the outer surface of the support body.

[0007] Preferably, an antibacterial layer is fixedly connected to the other end of the reinforcing layer, and an anti-corrosion layer is fixedly connected to the other end of the antibacterial layer.

[0008] Preferably, the reinforcing plates are evenly distributed on the support body, and the reinforcing plates are arranged in a triangular structure.

[0009] Preferably, both the upper and lower ends of the reinforcing frame are engaged with the support body, and the support body has a slot that cooperates with the reinforcing frame.

[0010] Preferably, threaded grooves are uniformly formed on the outer surfaces of both the upper and lower ends of the reinforcing rod, and the reinforcing rod is threadedly inserted into the bracket body.

[0011] Preferably, both the upper and lower ends of the reinforcing rod are fitted with washers, and the upper and lower ends of one set of washers abut against the bracket body and the reinforcing rod, while the upper and lower ends of the other set of washers abut against the nut and the bracket body.

[0012] This utility model provides a reinforcing structure for a refrigerator door support, which has the following advantages:

[0013] The reinforcing plate is fixed to the lower left side of the bracket body, effectively distributing the weight of the door and preventing deformation or breakage caused by excessive local stress. It enhances the bending resistance of the bracket, making it particularly suitable for scenarios where the door is heavy or needs to support many accessories (such as storage shelves). It is also snapped into the right side of the bracket body, forming a double-sided support structure, which further improves the rigidity and stability of the bracket, resists the lateral impact force when the door is opened and closed, and prevents the bracket from shaking or loosening. After being inserted into the bracket body, it is fixed with nuts to form longitudinal support, which significantly improves the compressive strength of the bracket and prevents the bracket from twisting or collapsing due to long-term load or external force. The reinforcing plate, reinforcing frame, and reinforcing rod work together to form a "triangular stable structure", extending the service life of the bracket.

[0014] To reduce wear and aging caused by frequent door opening and closing or environmental factors (such as humidity and high temperature), the reinforcing rod is secured with nuts to prevent loosening due to vibration or impact, thus improving the overall structural reliability. The reinforced structure effectively prevents the door from sagging or tilting due to its own weight or external forces, ensuring a tight fit between the door and the refrigerator body, reducing cold air leakage, lowering energy consumption, and improving the preservation effect. The reinforced structure also increases the rigidity of the bracket, reducing shaking and vibration when the door is opened and closed, thereby reducing noise and extending the service life of hinges, sealing strips, and other accessories.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a reinforcement structure for a refrigerator door bracket, including a bracket body 1, a reinforcement plate 2 fixedly connected to the lower left side of the bracket body 1, a reinforcement frame 3 snapped into the right side of the bracket body 1, a reinforcement rod 4 inserted on the bracket body 1, and a nut 5 sleeved on the lower end of the reinforcement rod 4.

[0024] The support body 1 includes a reinforcing layer 11, which is disposed on the outer surface of the support body 1. An antibacterial layer 12 is fixedly connected to the other end of the reinforcing layer 11, and an anti-corrosion layer 13 is fixedly connected to the other end of the antibacterial layer 12. The reinforcing layer 11 is typically made of high-strength materials (such as carbon fiber, glass fiber, or metal mesh), significantly improving the rigidity and bending resistance of the support body 1. This effectively prevents the support body 1 from deforming or breaking due to long-term load-bearing or external forces, extending its service life. It is suitable for high-end refrigerators or scenarios requiring the support of heavy doors, ensuring the support body 1 can withstand high loads. For stability, antibacterial materials (such as silver ion coating, nano antibacterial agents, or antibacterial plastics) are used to inhibit the growth of bacteria, mold, and other microorganisms on the surface of the support body 1, reduce odor generation, and keep the inside of the refrigerator clean. It is especially suitable for refrigerator doors where food is stored, and for scenarios with high hygiene requirements such as household refrigerators, commercial refrigerators, or medical refrigerators. It usually adopts chrome plating, zinc plating, anodizing, or anti-corrosion coating technology to effectively resist the corrosion of the support body 1 by humid, salt spray, and other corrosive environments, prevent the metal support body 1 from rusting or the plastic support from aging, and extend the service life of the support body 1.

[0025] Reinforcing plates 2 are evenly distributed on the support body 1, and the reinforcing plates 2 are arranged in a triangular structure. The upper and lower ends of the reinforcing frame 3 are both engaged with the support body 1, and the support body 1 has slots that cooperate with the reinforcing frame 3. The upper and lower ends of the reinforcing rod 4 are evenly provided with threaded grooves on their outer surfaces. The reinforcing rod 4 is threaded into the support body 1, and the upper and lower ends of the reinforcing rod 4 are fitted with washers. The upper and lower ends of one set of washers abut against the support body 1 and the reinforcing rod 4, and the upper and lower ends of the other set of washers abut against the nut 5 and the support body 1. The triangle is the optimal stability structure in mechanics, which can effectively distribute the force and resist bending and torsional deformation. The reinforcing plates 2 are evenly distributed on the support body 1, forming multi-point support, which significantly improves the overall rigidity and is suitable for large... For refrigerators with large doors or heavy loads, to prevent the door from sagging or deforming due to its own weight or external forces, the reinforcing frame 3 is fixed to the bracket body 1 through a snap-fit ​​structure at both ends, forming a "frame-like" support, further improving bending and torsional resistance. The matching design of the slots and the reinforcing frame 3 simplifies the installation process and avoids the risk of loosening that may be caused by screw fixing. It is suitable for doors that are frequently opened and closed, reducing the loosening or displacement of the bracket body 1 due to vibration. The outer surfaces of the upper and lower ends of the reinforcing rod 4 are provided with threaded grooves, which can be inserted into the threaded holes of the bracket body 1 by rotation to achieve fastening. The threaded design allows for adjustment of the tightness of the reinforcing rod 4 to adapt to different door weights or installation requirements. Gaskets are placed between the reinforcing rod 4 and the bracket body 1, and between the nut 5 and the bracket body 1. The spacers provide uniform clamping force, preventing localized stress concentration caused by threaded fastening. The gaskets also reduce metal-to-metal friction, extending the service life of the threads and nuts. Suitable for scenarios requiring precise adjustment of the bracket body 1's strength, such as high-end refrigerators or customized products, the three components combine to form a "triangular stability structure," enhancing the strength and stability of the bracket body 1 from multiple directions. This resists lateral impacts and prevents longitudinal deformation, comprehensively improving the door's safety and durability. Suitable for scenarios with extremely high performance requirements, such as commercial refrigerators, outdoor refrigerators, or smart refrigerators, the reinforcing plate 2, reinforcing frame 3, and reinforcing rod 4 can all be installed or replaced independently, facilitating future maintenance and upgrades. The snap-fit ​​structure and threaded insertion simplify the installation process and reduce labor costs. Through threaded tightening and shim adjustment, the strength of the bracket body 1 can be easily fine-tuned to adapt to different usage needs. The multiple reinforcement structures effectively prevent the door from tilting or sagging due to bracket body 1 failure, ensuring a tight fit between the door and the refrigerator body. Suitable for household refrigerators or commercial freezers with high sealing requirements, the reinforcement structure increases the rigidity of the bracket body 1, reducing door shaking and vibration during opening and closing, thereby reducing noise and extending the service life of hinges, sealing strips, and other accessories. Shims provide cushioning during threaded tightening, reducing direct metal-to-metal collision noise. The design of the reinforcing rod 4 and reinforcing frame 3 can be adjusted according to door size or load-bearing requirements to adapt to different refrigerator models. Space can be reserved in the bracket body 1 to integrate intelligent components such as sensors and wiring channels.The reinforcing plate 2, reinforcing frame 3, and reinforcing rod 4 can be made of stainless steel, aluminum alloy, or composite materials, taking into account the requirements of corrosion resistance, lightweight, and high strength.

[0026] Working principle: The reinforcing plate 2 is fixedly connected to the lower left side of the bracket body 1, usually by welding, riveting or screwing, forming a local reinforcement structure. The reinforcing plate 2 increases the local thickness and strength, balances the weight distribution of the door, and prevents the bracket body 1 from deforming or bending due to excessive force on one side. The triangular structure of the reinforcing plate 2 uses the "triangular stability principle" in mechanics to transfer the weight of the door to the bracket body 1, enhancing the overall bending resistance. When the door is opened or closed or when it is carrying heavy objects, the reinforcing plate 2 effectively disperses stress and avoids local damage to the bracket body 1. The reinforcing frame 3 is engaged on the right side of the bracket body 1 and is fixed by the slot opened on the bracket body 1. It is usually an embedded or mortise and tenon structure. The reinforcing frame 3 forms an integral part with the bracket body 1 through the engaging structure, resisting the lateral tensile force or impact force generated when the door is opened and closed, and preventing the bracket from shaking or displacing.
