DETAILED DESCRIPTION

[0028] See also Figure 1-6 As shown, the utility model relates to a multifunctional foot pad, comprising a non-slip base 5, a raised layer, an externally threaded sleeve 3, and an internally threaded sleeve, wherein the externally threaded sleeve 3, the raised layer, and the non-slip base 5 are connected in sequence from top to bottom (the connection is achieved in a detachable manner), wherein the internally threaded sleeve is threadedly connected to the outer side surface of the externally threaded sleeve 3, and a fitting groove 11 is provided on the top of the internally threaded sleeve, and the fitting groove 11 is provided with an adjustment locking member, and the adjustment locking member includes two locking plates 12, and the two locking plates 12 are both slidably fitted in the fitting groove 11, and an adjustment plate 113 is provided in the fitting groove 11, wherein a screw 13 passes through the locking plate 12 and the adjustment plate 113, and the two locking plates 12 are brought close to each other by rotating the screw 13.

[0029] Compared with traditional foot pads, users can freely assemble different numbers of raised layers according to actual needs, thereby achieving precise adjustment of the height of furniture / home appliances, etc. This design enables the foot pad to adapt to the height requirements of various furniture / home appliances, etc. and the ground, greatly increasing its scope of application and flexibility.

[0030] By setting an adjustable locking piece at the top of the internal threaded sleeve, the user can rotate the screw 13 to make the two locking plates 12 approach each other, thereby locking or releasing the supporting feet of furniture / home appliances, etc. This design is not only easy to operate, but also has a stable locking effect, which can ensure that the furniture / home appliances, etc. will not be displaced or tipped over due to the loosening of the foot pads during use.

[0031] The combined design of the mounting slot 11 on the top of the internal threaded sleeve and the adjusting locking piece enables the foot pad to be adapted to the supporting feet of furniture / home appliances of different sizes. Whether the supporting feet of the furniture / home appliances are slender or sturdy, the user can adapt to them by adjusting the position of the locking plate 12, which increases the versatility and practicality of the foot pad.

[0032] It should also be noted that the detachable assembly design between the external threaded sleeve 3, the raised layer, and the anti-slip base 5 makes the installation and removal of the foot pad very simple and convenient. The user can easily add or remove the raised layer as needed without using any special tools or skills. This design is also easy to clean and maintain. The user can easily disassemble the various parts of the foot pad for thorough cleaning or maintenance to keep it in good condition.

[0033] The design of the anti-skid base 5 can significantly enhance the friction between the foot pad and the ground, thereby effectively preventing furniture / home appliances from sliding or tilting due to slippery or uneven ground, ensuring the stability and safety of furniture / home appliances. In addition, through the threaded connection of the external threaded sleeve 3 and the internal threaded sleeve, the height of the foot pad can be easily adjusted. This design can cope with different usage scenarios. Since the height of the raised floor can be adjusted as needed, the user can appropriately adjust the height of the foot pad according to different usage scenarios.

[0034] Furthermore, the bottom surface of the anti-slip base 5 is provided with anti-slip grooves 52, and a plurality of first mounting columns 51 are protruding from the surface of the anti-slip base 5, and the bottom of the increased layer is provided with a first mounting slot 42 corresponding to the first mounting column 51, wherein the first mounting slot 42 of the increased layer is equipped with the first mounting column 51.

[0035] The anti-skid pattern 52 at the bottom of the anti-skid base 5 can greatly enhance the friction between the foot pad and the ground, effectively preventing furniture / home appliances from sliding or tilting due to wet or uneven ground. At the same time, the shock-absorbing pad can also effectively absorb and reduce the noise generated by furniture / home appliances due to vibration or impact, bringing a more peaceful and comfortable experience to the home environment. The first mounting column 51 on the surface of the anti-skid base 5 and the first mounting slot 42 at the bottom of the raised layer ensure the overall stability of the foot pad through a precise mounting structure. This design not only makes the installation process easier and faster, but also can maintain the stability of the foot pad for a long time, avoiding loosening or falling off during use.

[0036] It is also important to note that, through the design of the first mounting column 51 and the first mounting slot 42 at the bottom of the heightened layer, there is no need to use screws 13 for fixing, thereby achieving convenient assembly and disassembly. The user only needs to simply insert the first mounting column 51 into the corresponding first mounting slot 42 to achieve quick assembly of the foot pad. Similarly, when the foot pad needs to be removed, it is only necessary to pull the first mounting column 51 out of the slot without the use of any tools, which greatly improves the convenience and efficiency of assembly and disassembly. This design not only simplifies the installation process, but also provides users with a more flexible and convenient user experience.

[0037] Furthermore, the height-increasing layer includes one or more assembled height-increasing tubes 4, wherein a first fitting slot 42 is provided at the bottom of each assembled height-increasing tube 4, and a second fitting column 41 is protrudingly provided on the surface of the assembled height-increasing tube 4, and multiple assembled height-increasing tubes 4 are stacked by fitting their own second fitting columns 41 with the first fitting slot 42.

[0038] By introducing the design of the assembled height-increasing tube 4, the height-increasing layer of the supporting foot pad of this furniture / home appliance etc. shows higher flexibility and customizability. The bottom of each assembled height-increasing tube 4 is equipped with a first fitting slot 42, and the surface thereof is convexly provided with a second fitting column 41. This design enables multiple assembled height-increasing tubes 4 to be assembled with the first fitting slot 42 through their own second fitting columns 41, thereby achieving a stacking effect.

[0039] This stacking design provides great convenience for users, because users can freely choose the required number of assembling heightening tubes 4 according to the actual needs of furniture / home appliances, etc., and flexibly combine and adjust. (In this specific embodiment, 10mm and 20mm height assembling heightening tubes 4 are provided for customers to choose), and users can easily complete the stacking of assembling heightening tubes 4 to achieve precise adjustment of the foot pad height.

[0040] Furthermore, the bottom of the assembled heightening tube 4 is also provided with a reinforcing rib 43 connected to the first fitting slot 42. On the basis of introducing the assembled heightening tube 4, its structural design is further strengthened, that is, a reinforcing rib 43 connected to the first fitting slot 42 is provided at the bottom of the assembled heightening tube 4, which can significantly enhance the stability and load-bearing capacity of the entire foot pad. The design of the reinforcing rib 43 can not only effectively prevent the assembled heightening tube 4 from being deformed or loosened due to external force or load-bearing when stacked, but also strengthen the connection between each heightening tube, so that the entire heightening layer forms a more stable whole. In this way, whether in normal use or when subjected to unexpected impact, the foot pad can maintain stable performance and provide reliable support for furniture / home appliances, etc. At the same time, the provision of the reinforcing rib 43 can also improve the durability of the foot pad. Since the reinforcing rib 43 can share and withstand more pressure and impact force, it can reduce the wear and damage of the heightening tube itself and extend the service life of the foot pad.

[0041] Furthermore, a second fitting slot 31 is provided at the bottom of the externally threaded sleeve 3 , wherein the raised layer is fitted with the second fitting slot 31 of the externally threaded sleeve 3 via a second fitting column 41 .

[0042] This connection method allows the user to easily combine the raised layer with the external threaded sleeve 3 without using additional tools. The user only needs to align the second fitting column 41 on the raised layer with the second fitting slot 31 at the bottom of the external threaded sleeve 3, and then press to achieve a stable connection between the two. In addition, the fitting method of the second fitting column 41 and the second fitting slot 31 can also ensure that the foot pad maintains a stable connection state during long-term use. This design reduces the risk of loosening or falling off, and further improves the safety and reliability of the foot pad.

[0043] Furthermore, the internally threaded sleeve comprises an internally threaded locking ring 2 and an internally threaded supporting tube 1 , wherein the internally threaded locking ring 2 and the internally threaded supporting tube 1 are both threadedly connected to the externally threaded sleeve 3 , and the internally threaded supporting tube 1 is located above the internally threaded locking ring 2 .

[0044] Specifically, the user can easily adjust the height of the foot pad by rotating the internal thread support tube 1 to adapt to the needs of different furniture / home appliances and the ground. After adjusting to a suitable position, the user rotates the internal thread locking ring 2 to make it fit tightly with the bottom of the internal thread support tube 1. In this way, the internal thread locking ring 2 can play a locking role to prevent the internal thread support tube 1 from rotating when subjected to external force, thereby maintaining the stability of the height of the foot pad. This design not only improves the adaptability and flexibility of the foot pad, but also enhances its stability and safety. Users can easily complete height adjustment and locking without using any tools, which greatly improves the convenience of use. In addition, this design also takes into account the durability and long-term stability of the foot pad. Through the locking effect of the internal thread locking ring 2, the internal thread support tube 1 can be effectively prevented from loosening or deforming due to uneven force during long-term use, thereby extending the service life of the foot pad.

[0045] Furthermore, the locking plate 12 includes a locking plate 121 and a slider plate 122 located at the bottom of the locking plate 121, the slider plate 122 is provided with a first adjustment hole 1222, and the adjustment plate 113 located in the fitting slide groove 11 is provided with a second adjustment hole 1131, wherein the screw 13 passes through the first adjustment hole 1222 and the second adjustment hole 1131. By arranging the locking plate 121 and the slider plate 122 on the locking plate 12, and the corresponding adjustment holes (the first adjustment hole 1222 and the second adjustment hole 1131) thereon, the user can more finely adjust the position and locking force of the locking plate 12. The first adjustment hole 1222 on the slider plate 122 cooperates with the second adjustment hole 1131 on the adjustment plate 113, and by rotating the screw 13, the distance between the two locking plates 12 can be accurately adjusted to adapt to the supporting feet of furniture / home appliances of different sizes, and ensure a stable locking effect.

[0046] In this specific embodiment, the locking plate 121 is designed as a flat structure, so that it can be well adapted to the supporting feet of furniture / home appliances, etc. whose corresponding sides are flat. This design ensures the fit and stability between the foot pad and the supporting feet of the furniture / home appliances, etc., and reduces the possibility of loosening or sliding due to mismatch. When the locking plate 121 is tightly fitted with the plane of the supporting feet of the furniture / home appliances, etc., a strong locking force can be generated by adjusting the screw 13 to bring the two locking plates 12 closer to each other. This locking force ensures the stability of the supporting feet of the furniture / home appliances, etc. on the foot pad, and prevents the furniture / home appliances, etc. from tilting or moving due to loosening of the foot pad during use. This design greatly simplifies the installation steps and improves the installation efficiency.

[0047] When removing the multifunctional foot pad with the locking plate 121 design, you need to prepare a screwdriver suitable for removing the screw 13. Then, find the screw 13 located between the locking plates 121, and use the screwdriver to rotate the screw 13 counterclockwise to gradually loosen it. Due to the design characteristics of the screw 13, it may only be able to push the locking plate 121 but cannot be directly pulled back, so the user needs to manually pull the two locking plates 121 apart. Once the locking plates 121 are completely separated, they can be easily removed from the supporting feet of furniture / appliances, etc.

[0048] Furthermore, the slider plate 122 is further provided with a first easing hole 1223 , wherein the first easing hole 1223 of one slider plate 122 is aligned with the first adjustment hole 1222 of another slider plate 122 .

[0049] The first clearance hole 1223 is mainly used to prevent the screw 13 on one slider plate 122 from interfering with the other slider plate 122 when the two locking plates 12 are close to each other. Without the first clearance hole 1223, the screw 13 may contact the other slider plate 122 during the adjustment process, resulting in obstruction of the adjustment. With this hole, the screw 13 can smoothly pass through the two slider plates 122 without interference, ensuring a smooth adjustment process. In addition, the first clearance hole 1223 also enables the locking plate 12 to accurately adapt to the support feet of furniture / home appliances of different sizes, thereby improving the stability and durability of the locking mechanism.

[0050] See also Figure 7In addition, it should be noted that the adjustment plate 113 can be a solid plate structure and then a second adjustment hole 1131 with a thread is tapped, or a nut groove 1132 is opened on the adjustment plate 113, and a nut 1133 aligned with the second adjustment hole 1131 is installed in the nut groove, wherein the nut groove 1132 is a key design, which allows the user to accurately install the nut 1133 at the required position, that is, aligned with the second adjustment hole 1131. This design ensures that when the screw 13 passes through the first adjustment hole 1222 and the second adjustment hole 1131, it can be smoothly tightened with the nut 1133 and the position can be adjusted, thereby achieving the position adjustment of the locking plate 12. At the same time, the nut 1133 is installed in the nut groove 1132, which not only simplifies the installation process, but also improves the accuracy and stability of the installation. The close fit between the nut 1133 and the screw 13 makes it difficult for the locking plate 12 to loosen when subjected to external force, thereby ensuring the locking effect.

[0051] Moreover, one of the main functions of the adjustment plate 113 is to enable the two locking plates 12 to be freely moved and adjusted. This design allows the user to flexibly adjust the position of the locking plates 12 according to the size and shape of the furniture legs to ensure that the furniture legs can be accurately placed in the middle of the product. This flexibility greatly improves the adaptability and practicality of the foot pad. Compared with the existing design that uses a single-piece lock to move and adjust, the two locking plates 12 in this solution can ensure that the furniture legs remain in the middle position, which effectively prevents the furniture legs from collapsing sideways.

[0052] Furthermore, the inner walls on both sides of the mounting chute 11 are concavely provided with limiting grooves 111, and the two sides of the slider plate 122 are convexly provided with limiting protrusions 1221, wherein the slider plate 122 is mounted in the mounting chute 11 and the limiting protrusions 1221 are movably mounted in the limiting grooves 111. The limiting grooves 111 on the inner walls on both sides of the mounting chute 11 cooperate with the limiting protrusions 1221 on both sides of the slider plate 122, which not only limits the movement of the entire locking plate 12 in the vertical direction so that it cannot be directly pulled out vertically, but also ensures the accurate positioning and stable sliding of the slider plate 122 in the mounting chute 11. This design improves the accuracy, stability and durability of the locking mechanism.

[0053] Furthermore, the top of the internal thread support tube 1 is also provided with positioning grooves 112 located on both sides of the fitting slide groove 11, and the bottoms of both sides of the locking plate 121 are provided with positioning protrusions 1211, wherein the positioning protrusions 1211 are movably mounted in the positioning grooves 112. The matching design between the positioning grooves 112 at the top of the internal thread support tube 1 and the positioning protrusions 1211 on both sides of the locking plate 121 makes the installation and removal process of the locking plate 121 more convenient and quick. The user only needs to align the positioning protrusions 1211 with the positioning grooves 112 and gently push them in to complete the installation without the need for additional tools or complicated operation steps.

[0054] Furthermore, vertical anti-skid grooves 60 are distributed along the circumference of the anti-skid base 5 , the raised layer, and the outer side walls of the externally threaded sleeve 3 .

[0055] The vertical anti-skid groove 60 provides a clear guide for the assembly between components, allowing users to easily assemble the components together. During the installation process, users can ensure the correct position and angle between components by aligning the anti-skid grooves, thereby avoiding unnecessary misalignment or installation difficulties. For components that need to be rotated (such as the internal thread support cylinder 1), the vertical anti-skid groove 60 provides additional gripping points, allowing users to rotate these components more easily. Through the design of the anti-skid groove, users can obtain better grip and stability when rotating components, making it easier to complete operations such as adjustment or locking.

[0056] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention.
