Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator mounting components, and in particular to a novel screw fixing pad for refrigerators. Background Technology

[0002] In traditional refrigerator assembly, screw fixing spacers generally suffer from insufficient structural and environmental adaptability. The interior of a refrigerator is subjected to a unique environment of low temperature, high humidity, and temperature fluctuations. Ordinary spacers are prone to condensation buildup leading to corrosion at screw holes, or plastic deformation due to temperature changes, thus affecting the stability of the screw connection. Especially in scenarios where components need to penetrate the refrigerator wall (such as door hinges and shelf supports), conventional spacers lack effective drainage and ventilation channels. Condensation or airflow can easily stagnate around the screw holes, accelerating metal corrosion and potentially penetrating the insulation layer, reducing the refrigerator's energy efficiency.

[0003] Furthermore, most gaskets use a split design (such as an independent rubber gasket + metal insert), which involves complex manufacturing processes and is prone to water leakage at the joints; during installation, manual alignment of screws and gasket holes is required, resulting in low operational efficiency. Existing gaskets with adhesive layers face problems such as adhesive aging and peeling, and inability to adapt to the condensation surfaces on the refrigerator's inner wall. These defects collectively lead to pain points in refrigerator assembly, including poor connection reliability, high maintenance costs, and limited service life. There is an urgent need for an integrated fixing structure that can actively guide fluid, enhance sealing, simplify installation, and withstand harsh environments. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is: how to provide a new type of screw fixing pad for refrigerators to improve the product performance of screw fixing pads.

[0005] To achieve the above objectives, this utility model proposes a novel screw fixing pad for refrigerators, which includes a platform and a screw post.

[0006] The upper part of the platform is formed with a recessed portion, which extends downward in a vertical direction and is recessed. A through hole is provided inside the platform and below the recessed portion. A plurality of through holes are arranged in a vertical direction and arranged in a rectangular array. The through holes are used to transport airflow and / or liquid flow inside the recessed portion.

[0007] The screw post is provided inside the platform body and is accommodated in the arrangement space of the recessed portion. The height dimension of the screw post is greater than the depth dimension of the recessed portion, and the top surface of the screw post is higher than the top surface of the platform body in the height direction.

[0008] The screw post has a threaded hole inside, which is arranged along the axial direction of the screw post, and the outer diameter of the screw post is larger than the inner diameter of the through hole.

[0009] Furthermore, the platform and the screw post are integrally formed, and the platform is made of plastic.

[0010] Furthermore, the screw post is located at the center of the platform.

[0011] Furthermore, the bottom surface of the platform is provided with an adhesive surface, and the platform is connected to the refrigerator component through the adhesive surface.

[0012] Furthermore, the inner diameter of the through hole ranges from 1mm to 5mm.

[0013] Compared with related technologies, the present invention proposes a novel screw fixing pad for refrigerators, which has the following advantages: the recessed part on the upper part of the platform extends vertically downward and is recessed, and the interior of the platform below it is provided with multiple through holes arranged in a rectangular array along the vertical direction. This can effectively transport airflow and / or liquid flow in the recessed part, optimize the airflow circulation or liquid flow discharge inside the refrigerator, ensure uniform temperature inside the refrigerator, improve the cooling effect, and at the same time help prevent liquid accumulation, avoid bacterial growth or affecting the performance of components.

[0014] The screw post is housed within the recessed area, its height exceeding the depth of the recess, and its top surface extending above the top surface of the platform. It contains a threaded hole along its axis, with an outer diameter larger than the inner diameter of the through hole. This design ensures a more secure fit between the screw post and the screw, enhancing the reliability of the connection between the fixing pad and the refrigerator components, and preventing loosening after installation. Furthermore, the protruding screw post provides a clear positioning reference during installation, facilitating the installation process and improving efficiency.

[0015] The platform and screw posts are integrally molded from plastic, giving the fixing pad good integrity and a certain degree of elasticity. This ensures structural strength while also cushioning vibrations during installation and use, reducing the risk of component loosening or damage due to vibration. The bottom surface of the platform has an adhesive side for easy connection to refrigerator components, accommodating various shapes and materials of refrigerator parts, thus enhancing the fixing pad's applicability and installation flexibility.

[0017] Figure 2 This is a schematic diagram of the structure of a novel screw fixing pad for a refrigerator according to an embodiment of the present invention. Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Please see Figure 1 - Figure 2 As shown, this utility model proposes a novel screw fixing pad for refrigerators, which includes a platform 11 and a screw post 13.

[0020] The upper part of the platform 11 forms a recess 12, which extends vertically downward and is recessed. The recess 12 is used to accommodate the screw post 13, thereby limiting the space for the screw post 13. The height of the screw post 13 is greater than the depth of the recess 12, thus ensuring that the top surface of the screw post 13 is higher than the top surface of the platform 11. This provides a prominent mounting structure for screw connection, facilitates the fixing function with the screw, and enhances the reliability of the connection.

[0021] A through hole 14 is provided inside the platform 11 below the recessed portion 12. The recessed portion 12 serves as the inlet area for airflow and / or liquid flow and is connected to the through hole 14, so that the airflow and / or liquid flow inside the recessed portion 12 can be transported through the through hole 14, thereby optimizing the airflow circulation inside the refrigerator or discharging the liquid flow, avoiding liquid accumulation, and ensuring the cooling effect and component performance of the refrigerator.

[0022] In addition, the recessed portion 12 can also play a role in positioning and protecting the screw post 13 to a certain extent, ensuring the accurate position of the screw post 13 on the platform 11, and reducing the direct impact of external factors on the screw post 13 during installation and use.

[0023] A through hole 14 is provided inside the platform 11 and below the recess 12. Multiple through holes 14 are arranged vertically in a rectangular array. The inner diameter of the through hole 14 is in the range of 1mm-5mm. The through hole 14 is used to transport airflow and / or liquid flow inside the recess 12.

[0024] The through hole 14 serves as a transmission channel for airflow and / or liquid flow. After communicating with the recess 12, it can discharge the airflow or liquid flow inside the recess 12, thereby optimizing the airflow circulation inside the refrigerator, ensuring uniform cooling temperature, or timely draining liquid flow to prevent accumulation, avoid affecting component performance and bacteria growth.

[0025] The through holes 14 are distributed in a rectangular array. While realizing the fluid transport function, the structural strength of the platform 11 can be balanced by a reasonable hole diameter range (1mm-5mm) and array layout. This avoids the decrease in the strength of the platform 11 due to too many holes, while also taking into account the processing cost.

[0026] The through hole 14 is positioned to form a spatial fit with the screw post 13. The outer diameter of the screw post 13 is larger than the inner diameter of the through hole 14, which can avoid interference between the screw post 13 and the through hole 14 during installation. This ensures that the structural design of the screw post 13 protruding from the top surface of the platform 11 can be realized, thereby ensuring the reliability of the screw connection and the accuracy of the installation positioning.

[0027] The through holes 14 reduce the amount of material used in the platform 11 by creating holes inside the platform 11, thereby achieving a lightweight effect. Multiple through holes 14 are arranged in a rectangular array, which reasonably removes some material while ensuring the structural strength of the platform 11, avoiding a decline in structural performance due to excessive weight reduction, and balancing lightweight and structural reliability.

[0028] A screw post 13 is provided inside the platform 11. The platform 11 and the screw post 13 are integrally formed. The platform 11 is made of plastic. The screw post 13 is located at the center of the platform 11 and is accommodated in the arrangement space of the recess 12. The height of the screw post 13 is greater than the depth of the recess 12. The top surface of the screw post 13 is higher than the top surface of the platform 11 in the height direction.

[0029] The screw post 13 has a threaded hole inside, which is set along the axial direction of the screw post 13. The outer diameter of the screw post 13 is larger than the inner diameter of the through hole 14.

[0030] The screw post 13 is integrally molded and fixed inside the platform 11. Its top surface extends beyond the top surface of the platform 11 in the height direction, forming a raised threaded connection part. When the screw is screwed in, it preferentially engages with the higher screw post 13, avoiding blockage of the threaded hole due to residual condensate or foreign matter on the surface of the platform 11. At the same time, it ensures the center alignment accuracy of the screw and the pad, significantly reducing the risk of misalignment during assembly. The outer diameter of the screw post 13 is larger than the inner diameter of the through hole 14, forming a physical isolation barrier to prevent fluid from seeping into the threaded connection area through the through hole 14. This ensures a dry environment for the threaded pair while achieving airflow / liquid flow guidance.

[0031] The threaded hole is set through the axis of the screw post 13, and its structural strength is higher than that of traditional split metal inserts, which can withstand the alternating load caused by frequent opening and closing of the refrigerator door. The layout of the screw post 13 at the center of the platform 11 ensures that the fastening force is evenly transmitted to the adhesive surface, avoiding local stress concentration that could lead to adhesive peeling.

[0032] In addition, the design that the height of the screw post 13 is greater than the depth of the recess 12 creates a space gap between the screw head after tightening and the top surface of the platform 11, creating space conditions for condensate to flow along the side wall of the recess 12 to the through hole 14.

[0033] The bottom surface of the platform 11 is provided with an adhesive surface, and the platform 11 is connected to the refrigerator components through the adhesive surface.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
