Abstract
Description
Technical Field
[0001] This utility model relates to the field of foot pads, and in particular to a shockproof foot pad that prevents slippage. Background Technology
[0002] Foot pads are mat-like accessories placed between the ground and the bottom of objects, typically made of rubber, plastic, fabric, leather, silicone, or composite materials. Their shape and size are precisely designed according to the specific usage scenario. Common structures include flat, recessed, and curved types, and customized solutions can also be provided based on the shape of the bottom of home appliances. The surface often features anti-slip textures or adhesive structures to adapt to different floor materials, thus offering a wide range of applications and meeting the anti-slip and shock absorption needs of various home appliances.
[0003] During the operation of home appliances, continuous vibrations are generated during the spin-drying stage of washing machines, the operation of refrigerator compressors, and the operation of air conditioner outdoor units. If these appliances are in direct contact with a smooth surface, the vibrations can easily cause them to shift or tilt slightly. In severe cases, they may collide with surrounding furniture or walls, potentially damaging the appliance's casing or internal components, and even causing it to tip over due to tilting, posing a safety hazard. Installing feet on the bottom of appliances can enhance their stability against the ground through the friction or adhesion of the foot material, effectively limiting movement and preventing the aforementioned problems.
[0004] Regarding the aforementioned technologies, the inventors discovered in practice that when home appliances experience abnormal vibrations or high-frequency resonance, some of the foot pads already installed on the bottom may become loose. Specific scenarios include: washing machines vibrating beyond the normal range during spin-drying due to unevenly arranged clothes; refrigerators experiencing abnormal vibrations due to aging compressors or worn parts; and air conditioner outdoor units vibrating at high frequencies for extended periods due to uneven installation, loose brackets, or resonance with the wall. In these cases, even if some foot pads are designed with adhesive backing to enhance adhesion to the bottom of the appliance, the adhesive strength will gradually weaken under the continuous action of high-frequency vibration over a long period. Ultimately, the foot pads will peel off from the bottom of the appliance, causing them to lose their original fixing and shock-absorbing functions. Utility Model Content
[0005] The main technical problem solved by this utility model is to provide a shockproof foot pad that prevents appliances from falling off due to vibration during use, thereby maintaining the stability of the appliances during use.
[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a shockproof foot pad that prevents detachment, comprising: an elastic pad and an elastic limiting column assembly connected to the center of its top, the elastic limiting column assembly comprising symmetrically arranged arc-shaped elastic blocks, the top of the arc-shaped elastic blocks being respectively connected to limiting protrusions, and also comprising a V-shaped guide block, the inner projection of the limiting protrusions coinciding with the inner projection of the arc-shaped elastic blocks, the top and bottom ends of the limiting protrusions on opposite sides being respectively inclined;
[0007] The elastic pad has a countersunk hole, the arc of the inner circle of the countersunk hole matches the arc of the inner side of the arc-shaped elastic block, and also includes a limiting and fixing rod assembly inserted into the inner side of the arc-shaped elastic block. After the limiting and fixing rod assembly is inserted into the elastic limiting column assembly, it is suitable for preventing the inner side of the limiting protrusion from deforming, and the bottom of the limiting and fixing rod assembly is located in the countersunk hole.
[0008] By adopting the above technical solution, the elastic pad directly contacts the ground, bears the weight of the appliance, and initially disperses and buffers the vibration energy, while providing an installation base for other components. The elastic limiting column assembly absorbs and buffers the vibration energy generated by the appliance through its elastic properties, reducing the impact of vibration on the appliance and the ground. The V-shaped guide block plays a guiding role during installation or use, guiding the bottom of the appliance or other components to be accurately installed in the appropriate position. Under the action of the limiting and fixing rod assembly, it is inserted into the inner side of the arc-shaped elastic block, so that the part of the elastic limiting column assembly installed inside the appliance is limited, while preventing the inner side of the limiting protrusion from deforming. Thus, when the appliance vibrates and the arc-shaped elastic block tends to deform, the limiting and fixing rod assembly can limit its deformation range, ensuring that the limiting function of the limiting protrusion is not affected. Moreover, since the bottom of the limiting and fixing rod assembly and the bottom of the elastic pad are on the same horizontal plane, the bottom of the foot pad can be flat, ensuring that the foot pad can fully contact the ground, evenly distributing the weight and vibration energy of the appliance, and avoiding uneven force on the foot pad due to uneven bottom, which would affect the performance of the shockproof and anti-fall-off functions.
[0009] In a preferred embodiment, the present invention can be further configured as follows: the limiting and fixing rod assembly includes a T-shaped plug-in column, the top end of the plug-in column is provided with a through groove, elastic limiting pieces are symmetrically arranged in the through groove, the top ends of the elastic limiting pieces are respectively inclined downward, when the top end of the plug-in column is inserted into the top end of the limiting protrusion, the elastic limiting pieces are respectively located between the limiting protrusions, and the bottom of the elastic limiting pieces is located in the countersunk hole.
[0010] By adopting the above technical solution, the T-shaped cross-section plug-in column has good stability and guidance when inserted into the elastic gasket and elastic limiting column assembly. The transverse wing plate matches the countersunk hole, playing a role in positioning and preventing over-insertion. The longitudinal column is used to extend into the limiting protrusion to achieve the limiting function. At the same time, it works with the elastic limiting plate. Its elasticity allows it to deform when subjected to external force from the appliance pre-drilled hole during installation, thus smoothly inserting into the interior. Subsequently, it returns to its original shape, forming a limiting end face when its bottom end is reset. This allows the plug-in column to fill the limiting protrusion and prevent inner deformation, thereby ensuring that the limiting protrusion limits the appliance pre-drilled hole. At the same time, it works with the elastic limiting plate to fix the limiting fixing rod assembly and prevent it from falling off.
[0011] In a preferred embodiment, the present invention can be further configured such that: an annular locking groove is provided at the connection of the plug-in column, and an annular locking block matching the annular locking groove is connected to the bottom of the inner circle of the countersunk hole.
[0012] By adopting the above technical solution, the annular locking groove provides a specific space and shape for cooperation with the relevant structure inside the countersunk hole. When the plug-in column of the limiting and fixing rod assembly is inserted into the countersunk hole, the locking groove can form a tight locking relationship with the annular locking block, preventing the plug-in column from easily coming out of the countersunk hole under vibration, external force pulling, etc., thereby ensuring the firmness of the connection between the limiting and fixing rod assembly and the elastic gasket.
[0013] In a preferred embodiment, the present invention can be further configured such that a disassembly hole is provided at the bottom end of the plug-in column.
[0014] By adopting the above technical solution, when the floor mats age after being placed on the ground for a long time, they can be disassembled through the disassembly holes and other disassembly tools for replacement.
[0015] In a preferred embodiment, the present invention can be further configured such that annular grooves are respectively formed at the top and bottom of the elastic pad.
[0016] By adopting the above technical solution, when the weight and vibration of the home appliance are transmitted to the elastic pad, the top annular groove can play a role in stress dispersion. It can disperse the force concentrated on a certain point to the surrounding area of the annular groove, avoiding excessive local stress that could damage the elastic pad or connecting parts, and improving the load-bearing capacity and resistance to damage of the entire foot pad structure.
[0017] In a preferred embodiment, the present invention can be further configured such that the top end of the plug-in column is conical.
[0018] By adopting the above technical solution, the conical tip has a guiding function. When inserting the plug into the countersunk hole on the elastic gasket, the conical shape makes it easier for the plug to be positioned correctly. Even if the operator has a certain angular deviation during installation, the conical tip can gradually guide the plug into the correct position, reducing installation failures or repeated adjustments caused by alignment difficulties.
[0019] In summary, this utility model includes at least one of the following beneficial technical effects of anti-fall-off shockproof foot pads:
[0020] 1. When the plug-in column is inserted into the inner side of the arc-shaped elastic block, the elastic limiting piece is compressed and retracts into the through groove so that the plug-in column can be smoothly inserted into the top of the limiting protrusion. After installation, the elastic limiting piece unfolds from the through groove by its own elasticity to achieve the locking function and fills the inner side of the limiting protrusion to prevent it from deforming. The bottom limit after the elastic limiting piece is reset restricts its overall longitudinal displacement to prevent the elastic pad from loosening and falling out under high-frequency vibration.
[0021] 2. Under the weight of the foot pad itself and the pressure applied by the appliance, the bottom suction groove of the plug-in column forms a negative pressure, generating suction force, which makes the bottom of the plug-in column tightly fit the contact surface, enhancing the adhesion to the ground and preventing the foot pad from sliding or detaching due to external forces such as vibration of the appliance. On the other hand, the annular groove on the top of the elastic pad and the limiting protrusion and other components form a nested or interlocking structure, increasing the tightness of the connection and the friction.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0030] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0031] Reference Figure 1-3 This utility model discloses an anti-fall-off shockproof foot pad, comprising: an elastic pad 1 and an elastic limiting column assembly 20 connected to the top center of the elastic pad 1. The top and bottom of the elastic pad 1 are respectively provided with annular grooves 6. The elastic limiting column assembly 20 includes symmetrically arranged arc-shaped elastic blocks 21. The top of the arc-shaped elastic blocks 21 is respectively connected with limiting protrusions 22. It also includes a V-shaped guide block 23. The inner projection of the limiting protrusions 22 coincides with the inner projection of the arc-shaped elastic blocks 21. The top and bottom of the opposite side of the limiting protrusions 22 are respectively inclined. The elastic pad 1 is provided with a countersunk hole 3. The arc of the inner circle of the countersunk hole 3 matches the inner arc of the arc-shaped elastic blocks 21. It also includes a limiting fixing rod assembly 40 inserted into the inner side of the arc-shaped elastic blocks 21. After the limiting fixing rod assembly 40 is inserted into the elastic limiting column assembly 20, it is used to prevent the inner side of the limiting protrusions 22 from deforming. The bottom of the limiting fixing rod assembly 40 is located in the countersunk hole 3.
[0032] The annular grooves 6 at the top and bottom of the elastic pad 1 increase the roughness of the contact surface between the elastic pad 1 and the ground and the bottom of the appliance. When the foot pad is placed on the ground, the annular grooves 6 can better adhere to the ground, and they have a certain elastic deformation space to adapt to the deformation of the ground, ensuring that the elastic pad 1 always maintains good contact with the ground, maintaining stable support and anti-slip effect, and further enhancing the anti-fall-off performance. When the shock-absorbing foot pad is installed in the reserved hole at the bottom of the appliance, the V-shaped guide block 23 plays a guiding role and deforms, while the arc-shaped... A clearance gap is formed between the elastic block 21 and the limiting protrusion 22, and the elastic block deforms as it is gradually inserted into the reserved hole to ensure that the whole assembly is installed in the right position. The elastic limiting column assembly 20 is made of hard rubber or nylon, and its main body is inserted into the inner side of the arc-shaped elastic block 21 to expand the inner side of the arc-shaped elastic block 21 and the inner side of the limiting protrusion 22, thereby preventing the inner side of the limiting protrusion 22 from deforming. Since its surface protrudes outward, it can play a limiting role, preventing the appliance from sliding out between the limiting protrusions 22 during vibration and improving the reliability of anti-falling.
[0033] The limiting and fixing rod assembly 40 includes a T-shaped insertion column 41. A through groove 42 is provided at the top of the insertion column 41. Elastic limiting pieces 43 are symmetrically arranged in the through groove 42. The tops of the elastic limiting pieces 43 are respectively inclined downward. When the top of the insertion column 41 is inserted into the top of the limiting protrusion 22, the elastic limiting pieces 43 are respectively located between the limiting protrusions 22, and the bottom of the elastic limiting pieces 43 is located in the countersunk hole 3. A disassembly hole 45 is provided at the bottom of the insertion column 41, and the top of the insertion column 41 is conical.
[0034] The through groove 42 provides the necessary deformation space for the elastic limiting piece 43. During installation, the elastic limiting piece 43 can retract into the through groove 42, greatly reducing the resistance of the insertion post 41 into the top of the limiting protrusion 22, facilitating smooth installation. After installation, the elastic limiting piece 43 can unfold from the through groove 42 by its own elasticity, accurately achieving the locking function. The inclined top of the elastic limiting piece 43 can slide smoothly along the inner inclined surface of the limiting protrusion 22 and easily enter the limiting protrusion through its own elastic contraction. The space between 22, and when the top of the insertion post 41 is inserted into the top of the limiting protrusion 22, the elastic limiting piece 43 unfolds from the through groove 42, and its outer side is tightly attached to the inner side wall of the limiting protrusion 22, forming a stable "lateral support"; when the limiting protrusion 22 tends to retract inward under high frequency vibration, the bottom end of the elastic limiting piece 43 forms a "reverse engagement" with the top inner wall of the mounting hole at the bottom of the appliance, thereby preventing the limiting protrusion 22 from retracting, thus preventing it from detaching in the reverse direction, further reducing the risk of falling off.
[0035] An annular locking groove 44 is provided at the connection of the plug-in column 41, and an annular locking block 5 that matches the annular locking groove 44 is connected to the bottom of the inner circle of the countersunk hole 3.
[0036] The vertical column part of the plug-in column 41 can be tightly inserted into the inner side of the arc-shaped elastic block 21, forming a connection with the original structure, effectively restricting the inward deformation of the arc-shaped elastic block 21. After its transverse flange is inserted into place, the annular locking groove 44 can form a tight locking relationship with the annular locking block 5, preventing the plug-in column 41 from easily coming out of the countersunk hole 3 under the condition of vibration, external force pulling, etc.
[0037] The implementation principle of this embodiment is as follows: In use, firstly, the limiting and fixing rod assembly 40 is inserted between the arc-shaped elastic blocks 21. Then, the V-shaped guide block 23 is aligned with the reserved mounting hole on the appliance. Since the V-shaped guide block 23 has a guiding function, it can guide the appliance to be inserted accurately. Subsequently, the limiting protrusion 22 deforms and moves towards each other, so that the whole assembly is inserted above the reserved hole. At this time, the elastic limiting column assembly 20 is pressed, so that the bottom end of the insertion column 41 gradually enters the countersunk hole 3 until the assembly is fully installed, ensuring that the countersunk hole 3 at the bottom end of the insertion column 41 fits tightly. At this time, the annular locking groove 44 can form a tight locking relationship with the annular locking block 5, and the top end of its insertion column 41 is also inserted into the inner top end of the limiting protrusion 22, expanding the inner side of the arc-shaped elastic block 21 and the inner side of the limiting protrusion 22. This prevents the inner side of the limiting protrusion 22 from deforming. Since its surface protrudes outward, it can play a limiting role, preventing the appliance from sliding out between the limiting protrusions 22 during vibration and improving the reliability of anti-falling. In addition, during the insertion process, the inclined surface of the top of the elastic limiting piece 43 is pressed and will be smoothly squeezed and entered between the limiting protrusions 22. As the insertion goes deeper, the elastic limiting piece 43 will return to its original position due to its own elasticity and be stuck at the top of the reserved hole to achieve locking and limiting. When the foot pad is vibrated and tends to fall downward, the limiting protrusion 22 will be firmly pressed against the top of the reserved hole by the expansion and squeezing action of the insertion column 41, preventing it from falling out in the opposite direction. At the same time, after the elastic limiting piece 43 unfolds from the through groove 42, its bottom end is tightly attached to the top wall of the reserved hole, and the locking state is maintained, thereby preventing the foot pad from falling out.
[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
