Description

Technical Field

[0001] This utility model relates to the field of foot pads, and in particular to a push-in anti-slip foot pad. Background Technology

[0002] Foot mats are a type of sheet or block-shaped auxiliary component widely used in homes, automobiles, industrial equipment, public spaces, and other scenarios. They are mainly made of rubber, plastic, fiber, leather, etc., and have functions such as anti-slip, protection, shock absorption, and cleaning. The core function is to solve safety, protection, and comfort issues during use by adhering to the ground, equipment base, or contact surface. Their shape and size are precisely designed according to the specific usage scenario. Common structures include flat, grooved, and curved types. Customized solutions can also be provided according to the bottom shape of home appliances. The surface often has anti-slip textures or adsorption structures to adapt to different ground environments. Therefore, they have a wide range of applications and can meet the anti-slip and shock absorption needs of various home appliances.

[0003] Many home appliances vibrate to varying degrees during operation, such as washing machines during the spin cycle and refrigerator compressors during operation. Installing suitable feet can effectively reduce noise caused by vibration, increase friction between the appliance and the ground, prevent the appliance from shifting during operation, and avoid collision damage or safety hazards caused by displacement. In addition, feet can prevent the bottom of the appliance from directly contacting the ground, reducing wear and damage caused by friction and scratches. For example, the bottom of a metal refrigerator is prone to scratches and may rust if it comes into direct contact with a rough ground. Using feet can effectively prevent this. At the same time, for appliances used in humid environments such as kitchens and bathrooms, feet can keep the bottom of the appliance a certain distance from the damp ground, reducing the corrosion of the bottom parts by moisture and lowering the probability of malfunctions such as short circuits and rust caused by moisture.

[0004] In response to the above-mentioned situations, the inventors discovered that the vibrations generated during the operation of some home appliances can cause the bottom feet to detach. In addition, during the handling and moving of some home appliances, the elastic material of the feet may gradually harden due to creep effect because it has been subjected to static pressure for a long time. This weakens the adhesion or friction, causing the feet to fall off and 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 push-in anti-detachment foot pad to prevent the foot pad from detaching from the bottom of the appliance, thereby making its operation stable.

[0006] To solve the above technical problems, the present invention adopts a technical solution as follows: a push-in anti-slip foot pad is provided, comprising: a rubber pad and a sleeve assembly with a T-shaped cross section, wherein a T-shaped locking rod assembly is inserted into the sleeve assembly, a through hole is provided on the rubber pad, a groove is provided at the bottom of the rubber pad, the groove is connected to the through hole, and the sleeve assembly is inserted into the through hole; The sleeve assembly includes a tapered mounting ring and several L-shaped limiting pins spaced apart at its top. A clearance gap is formed between two adjacent limiting pins. The projection of the through hole coincides with the projection of the several limiting pins. When the T-shaped locking rod assembly is inserted into the sleeve assembly and its top is above the top of the sleeve assembly, the top of the sleeve assembly opens outward and expands radially, and the bottom of the T-shaped locking rod assembly is parallel to the bottom of the rubber pad.

[0007] By adopting the above technical solution, the rubber pad provides cushioning during use and increases the adhesion between the foot pad and the contact surface, preventing the foot pad from slipping off. The groove guides the sleeve assembly to accurately insert into the through hole, allowing the bottom of the foot pad to better fit the contact surface and reducing installation instability caused by local unevenness. For the sleeve assembly, the insertion of the T-shaped locking rod assembly deforms the end of the sleeve assembly, achieving a locking effect. The tapered design makes it easier to insert the sleeve assembly into the rubber pad through hole. As the insertion depth of the limiting pin increases, the tapered structure gradually fits tightly against the inner wall of the through hole, providing guidance and initial fixation. During insertion, it provides space for deformation of the top of the sleeve assembly. When the T-shaped locking rod assembly is inserted to a certain position, its top extends beyond the top of the sleeve assembly, applying an outward force to the top of the sleeve assembly, causing it to open outward and radially tighten. This tightening force generates significant friction between the sleeve assembly and the inner wall of the rubber pad through hole, as well as the wall of any potential installation hole, thus ensuring reliable foot pad fixation and preventing it from falling off.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the T-shaped locking rod assembly includes a plug rod and a connecting plate connected to its bottom; the inner diameter projection of the conical mounting ring coincides with the projection of the plug rod; the projection of the groove coincides with the projection of the connecting plate; a conical groove is provided on the top of the connecting plate; an annular groove is provided in the groove; an elastic limiting ring is provided in the annular groove and connected to the outer circular surface of the connecting plate; the conical groove is adapted to the bottom of the conical mounting ring; and a thumb groove is provided on one side of the bottom of the connecting plate.

[0009] By adopting the above technical solution, the insert rod is the main insertion part. By varying the insertion depth and position of the insert rod within the sleeve assembly, the deformation degree of the sleeve assembly can be precisely controlled, thereby adjusting the locking force. The interaction between the connecting plate and the bottom of the rubber pad better disperses the pressure on the foot pad, making it more stable during use. Furthermore, the projection of the groove coincides with the projection of the connecting plate, allowing the connecting plate to be accurately placed within the groove at the bottom of the rubber pad, achieving precise positioning between the connecting plate and the rubber pad. The tapered groove matches the bottom of the tapered mounting ring, increasing the connection stability and sealing between the T-shaped locking rod assembly and the sleeve assembly. When the T-shaped locking rod assembly is inserted into the sleeve assembly, the bottom of the tapered mounting ring can be tightly embedded in the tapered groove, forming a relatively closed space. This reduces the possibility of dust, moisture, and other impurities entering the sleeve assembly, helping to protect the internal structure and extend the service life of the foot pad. The annular groove provides installation space for the elastic limiting ring, allowing it to be accurately fixed in the groove of the rubber pad. When the foot pad is subjected to external force, the elastic limiting ring can absorb some energy, reducing the direct impact between the connecting plate and the rubber pad, preventing the connecting plate from loosening or being damaged. At the same time, it can also limit the movement range of the connecting plate in the groove, ensuring the relative position stability of the connecting plate and the rubber pad, further improving the anti-dislodgement performance of the foot pad. On the other hand, when installing or removing the foot pad, the user can put their thumb into the groove to more easily apply force to rotate or insert / remove the T-shaped locking rod assembly, improving the convenience and efficiency of operation.

[0010] In a preferred embodiment, the present invention can be further configured such that: an annular groove two is provided in the groove above the annular groove one, and an elastic limiting ring two is provided in the annular groove two and connected to the outer circular surface of the conical mounting ring.

[0011] By adopting the above technical solution, the first annular groove restricts the movement of the connecting disc within the groove through the first elastic limiting ring. The second annular groove, in conjunction with the second elastic limiting ring, limits the conical mounting ring of the sleeve assembly from another position and angle, making the connection between the sleeve assembly and the rubber pad more stable. This effectively prevents the sleeve assembly from loosening or shifting due to external forces during use, thus ensuring the stability and reliability of the entire push-in anti-slip foot pad structure. The first and second elastic limiting rings work together. When the foot pad is subjected to external forces of different directions or types, the two elastic limiting rings can respectively play a limiting role according to the force. When the foot pad is subjected to vertical compression, the second elastic limiting ring can better bear and disperse this force, preventing the conical mounting ring from moving upwards. When subjected to horizontal forces, the first and second elastic limiting rings work together to limit the horizontal displacement of the sleeve assembly, further improving the stability of the structure.

[0012] In a preferred embodiment, the present invention can be further configured such that the top of the limiting post has a rounded corner.

[0013] By adopting the above technical solution, during the process of inserting the sleeve assembly into the through hole of the rubber pad, the rounded corner at the top of the limiting post plays a guiding role. Since the edge of the through hole and the limiting post need to be precisely matched, the rounded corner can make the limiting post enter the through hole more smoothly, avoiding the jamming phenomenon caused by the collision between the sharp corner and the edge of the through hole, which greatly improves the efficiency and accuracy of installation.

[0014] In a preferred embodiment, the present invention can be further configured such that at least one annular adsorption groove is formed at the bottom of the rubber pad.

[0015] By adopting the above technical solution, the ring-shaped adsorption groove increases the actual contact area between the bottom of the rubber pad and the contact surface. Compared with flat contact, after opening the ring-shaped adsorption groove, more micro-contact areas are formed between the rubber pad and the contact surface. Under the principle of vacuum adsorption, more air can be adsorbed, thereby generating a greater adsorption force, making the foot pad more firmly fixed on the contact surface, and effectively preventing the foot pad from sliding or shifting during use.

[0016] In a preferred embodiment, the present invention can be further configured such that the cross-section of the rubber pad is either conical or rectangular.

[0017] By adopting the above technical solution, in some installation space-constrained scenarios, especially where the bottom space is small and the upper space is relatively large, the rubber pad with a conical cross-section can better adapt to this spatial structure. The conical shape of the rubber pad can guide the external force to be dispersed and transmitted along the conical slope. When the foot pad is subjected to vertical downward pressure, the pressure will gradually diffuse outwards along the conical slope, rather than being concentrated on a certain point, thereby changing the force transmission path.

[0018] In summary, this utility model includes at least one of the following beneficial technical effects of push-in anti-slip foot pads: The limiting pins of the sleeve assembly engage with the bottom mounting structure of the appliance at multiple points, and the T-shaped locking rod assembly, after being inserted into the sleeve assembly, causes the limiting pins to expand radially, tightly fitting against the inner wall of the through hole or the appliance mounting hole to generate friction, effectively preventing loosening. At the same time, the first and second elastic limiting rings form a double-layer locking mechanism, restricting the longitudinal displacement of the sleeve assembly. Even if the T-shaped locking rod assembly accidentally comes loose, it can prevent the foot pad from detaching from the bottom of the appliance, greatly enhancing the stability of the connection and the anti-detachment performance.

[0019] The rounded corner design at the top of the limiting plug prevents jamming when inserting into the appliance mounting hole, reduces assembly resistance, and makes the installation process smoother. The thumb groove at the bottom of the connecting plate allows users to apply force to operate the T-shaped locking rod assembly when installing or removing the foot pads, improving the convenience and efficiency of maintenance operations and saving time and labor costs.

[0022] 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.

[0023] 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.

[0024] Reference Figure 1-3This utility model discloses a push-in anti-slip foot pad, comprising: a rubber pad 1 and a sleeve assembly 20 with a T-shaped cross-section. A T-shaped locking rod assembly 30 is inserted into the sleeve assembly 20. The rubber pad 1 has a through hole 4 and a groove 5 at its bottom, which communicates with the through hole 4. The sleeve assembly 20 is inserted into the through hole 4. The sleeve assembly 20 includes a conical mounting ring 21 and several L-shaped limiting pins 22 spaced apart at its top. The top of the limiting pins 22 is rounded, and a clearance gap 23 is formed between two adjacent limiting pins 22. The projection of the through hole 4 coincides with the projection of the several limiting pins 22. When the T-shaped locking rod assembly 30 is inserted into the sleeve assembly 20 and its top is above the top of the sleeve assembly 20, the top of the sleeve assembly 20 opens outward and expands radially, and the bottom of the T-shaped locking rod assembly 30 is parallel to the bottom of the rubber pad 1.

[0025] Rubber pad 1 provides elastic support, anti-slip and shock absorption. The upper part of the sleeve assembly 20 is connected to the bottom of the appliance, and the lower tapered mounting ring 21 is located in the groove 5 of the rubber pad 1, thereby indirectly fixing the appliance to the rubber pad 1. The limiting post 22 engages with the bottom mounting structure of the appliance. When the T-shaped locking rod assembly 30 is inserted, it opens outward to achieve tightening. The horizontal section of the L-shaped structure of the limiting post 22 forms a multi-point engagement with the bottom of the appliance, enhancing the connection stability. Its top rounded corner design avoids jamming when inserted into the appliance mounting hole, reducing assembly resistance. When the T-shaped locking rod assembly 30 is inserted between the limiting posts 22, the clearance gap 23 opens radially to provide deformation space, ensuring smooth tightening action. After opening outward, it fits tightly with the inner wall of the through hole 4 or the appliance mounting hole, generating friction to prevent loosening.

[0026] The T-shaped locking rod assembly 30 includes a rod 31 and a connecting plate 32 connected to its bottom. The inner diameter projection of the conical mounting ring 21 coincides with the projection of the rod 31, and the projection of the groove 5 coincides with the projection of the connecting plate 32. A conical groove 33 is provided on the top of the connecting plate 32. An annular groove 6 is provided in the groove 5. An elastic limiting ring 34 connected to the outer circular surface of the connecting plate 32 is provided in the annular groove 6. The conical groove 33 is adapted to the bottom of the conical mounting ring 21. A thumb groove 35 is provided on one side of the bottom of the connecting plate 32. An annular groove 7 located above the annular groove 6 is provided in the groove 5. An elastic limiting ring 24 connected to the outer circular surface of the conical mounting ring 21 is provided in the annular groove 7.

[0027] The insertion rod 31 is made of hard rubber, and its top is hemispherical. When it is inserted into the sleeve assembly 20, it transmits the tightening force and simultaneously achieves precise positioning by matching the inner diameter of the conical mounting ring 21. Its outer diameter coincides with the projection of the inner diameter of the conical mounting ring 21, ensuring that it is always inserted along the central axis direction to avoid deviation. After insertion, it squeezes all the limiting insertion posts 22 to ensure that the insertion posts open radially synchronously, avoiding loosening caused by insufficient tightening on one side. At the same time, the conical mounting ring 21 fits tightly with the groove 5, further improving its overall stability. The conical groove 33 matches the bottom of the conical mounting ring 21 to form a conical surface fit, eliminating the assembly gap between the two and limiting the downward displacement of the sleeve assembly 20, preventing the sleeve assembly 20 from coming out of the through hole 4 of the rubber pad 1 due to long-term vibration. Ring 34, through its elastic deformation, engages with the annular groove 6 of the rubber pad 1, preventing the connecting plate 32 from detaching upwards from the groove 5. On the other hand, when installing or removing the foot pad, the user can place their fingers into the thumb groove 35 to more easily apply force to disassemble the T-shaped locking rod assembly 30, improving the convenience and efficiency of maintenance operations. The annular groove 7 provides engagement space for the elastic limiting ring 24, whose size precisely matches the limiting ring. At the same time, it forms a double-layer locking with the annular groove 6, restricting the longitudinal displacement of the sleeve assembly 20. Its elastic characteristics can absorb longitudinal vibration impact. Even if the T-shaped locking rod assembly 30 is accidentally loosened, the elastic limiting ring 24 can still fix the sleeve assembly 20 on the rubber pad 1, preventing the entire foot pad from detaching from the bottom of the appliance and reducing the risk of sudden safety incidents.

[0028] The bottom of the rubber pad 1 has at least one annular adsorption groove 8.

[0029] The ring-shaped adsorption groove 8 increases the actual contact area between the bottom of the rubber pad 1 and the contact surface. Compared with flat contact, the ring-shaped adsorption groove 8 creates more micro-contact areas between the rubber pad 1 and the contact surface. Under the principle of vacuum adsorption, it can adsorb more air, thereby generating a greater adsorption force, making the foot pad more firmly fixed on the contact surface, and effectively preventing the foot pad from sliding or shifting during use.

[0030] The cross-section of rubber pad 1 is either conical or rectangular.

[0031] The implementation principle of this embodiment is as follows: During use, the rubber pad 1 is placed at the target installation position on the bottom of the appliance, aligning the through hole 4 on the rubber pad 1 with the corresponding installation hole on the bottom of the appliance. The annular adsorption groove 8 at the bottom of the rubber pad 1 faces the contact surface. The adsorption force generated by the annular adsorption groove 8 initially fixes the position of the rubber pad 1, preventing it from sliding. Then, holding the sleeve assembly 20 with the conical mounting ring 21 facing downwards, the several L-shaped limiting pins 22 are aligned with the through hole 4 on the rubber pad 1. Since the projection of the through hole 4 coincides with the projection of the several limiting pins 22, the accuracy of the insertion direction is ensured. The sleeve assembly 20 is slowly inserted into the through hole 4 until the conical mounting ring 21 is completely inserted into the groove 5 at the bottom of the rubber pad 1. At this point, the L-shaped transverse section of the limiting pin 22 initially contacts the bottom mounting structure of the appliance. Its rounded top design prevents jamming during insertion and reduces assembly resistance. Then, the top of the insert 31 is aligned with the top opening of the sleeve assembly 20. Since the insert 31 is made of hard rubber and its outer diameter coincides with the inner diameter projection of the conical mounting ring 21, it ensures that the insertion is always along the central axis direction, avoiding deviation. Slowly insert the T-shaped locking rod assembly 30 into the sleeve assembly 20. As the insert 31 is inserted, it will squeeze all the limiting pins 22, allowing the clearance 23 to provide deformation space for the limiting pins 22, causing the limiting pins 22 to open outward and expand radially. Continue insertion until the bottom of the T-shaped locking rod assembly 30 is parallel to the bottom of the rubber pad 1. At this point, the conical groove 33 fits and conforms to the bottom of the conical mounting ring 21, forming a conical surface fit, eliminating the assembly gap between the two, thereby achieving an anti-dislodgement effect.

[0032] 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.
