[0001] This utility model relates to the technical field of furniture, and specifically discloses a three-dimensional adjustable foot cover. Background Technology
[0002] Leg covers are a common component in the furniture industry, typically installed on the bottom of furniture such as wardrobes and cabinets. Their main function is to support the furniture, preventing the bottom from directly contacting the ground and being damaged by moisture. They also allow for adjustment of the furniture's level by adjusting its height to adapt to different ground conditions, ensuring both stability and aesthetics. Furthermore, leg covers can also protect the floor to some extent, preventing scratches when moving the furniture.
[0003] However, most existing furniture feet can only be adjusted in one direction, such as height (along the z-axis), and cannot be adjusted simultaneously in the horizontal direction (x-axis and y-axis). This single-adjustment function often fails to achieve the desired installation effect when facing uneven ground or furniture installation misalignment. For example, in some special installation scenarios, it may be necessary to fine-tune the furniture to adapt to a specific spatial layout; the adjustment function of existing furniture feet cannot meet these needs, limiting the installation flexibility and applicability of the furniture. Therefore, a three-dimensional adjustable furniture foot is needed. Utility Model Content

The second adjusting seat 5 is slidably connected to the first adjusting seat 4 and has a left-to-right adjusting lever 8. The top surface of the first adjusting seat 4 has a rack 41 extending along the x-axis. The left-to-right adjusting lever 8 has a gear portion 81 that meshes with the rack 41, thereby driving the second adjusting seat 5 to move along the x-axis. The third adjusting seat 6 is fixed to the second adjusting seat 5 and the lower foot sleeve 2. The upper foot sleeve 3 is slidably connected to the lower foot sleeve 2 along the y-axis. The bottom of the upper foot sleeve 3 is provided with a connecting plate 31, and a transmission screw 10 parallel to the axial direction of the upper foot sleeve 3 is mounted on the connecting plate 31. The bottom end of the transmission screw 10 is fixed with a worm gear 101 and rotatably connected to the third adjusting seat 6. The third adjusting seat 6 is provided with an up-and-down adjusting rod 9, and the up-and-down adjusting rod 9 is provided with a worm gear part 91 that meshes with the worm gear 101 to drive the upper foot sleeve 3 to move along the y-axis. This structural design allows the foot sleeve to be flexibly adjusted in three-dimensional space, which can well adapt to different installation environments, meet the requirements of height, levelness and other aspects during furniture installation, improve the convenience and adaptability of furniture installation, effectively avoid furniture installation problems caused by uneven ground and other factors, and extend the service life of furniture.
[0030] As a preferred design, the ends of the front-to-back adjusting lever 7, the left-to-right adjusting lever 8, and the up-to-down adjusting lever 9 all extend from the same side of the three-dimensional adjustable feet. This design allows operators to adjust the feet from the same side without having to move or change the operating position multiple times around the feet, improving adjustment efficiency, simplifying the operation process, and making foot adjustment more convenient and faster. This further enhances work efficiency during furniture assembly, especially when assembling large furniture or when frequent foot adjustments are required.
[0031] As a preferred embodiment, the first adjusting seat 4 and the second adjusting seat 5 are slidably connected by a slot 42 that engages with a locking block 51, with the slot 42 preventing the locking block 51 from disengaging along the z-axis. This engagement structure of the slot 42 and the locking block 51 ensures the stability of the connection between the first adjusting seat 4 and the second adjusting seat 5, while also preventing the second adjusting seat 5 from loosening or falling off along the z-axis when moving along the x-axis. This ensures the overall structural reliability of the foot cover during adjustment, preventing unstable furniture installation due to loosening of components, which could affect the normal use and stability of the furniture, and providing more reliable support and adjustment functions for the furniture.
[0032] As a preferred embodiment, the slot 42 and the locking block 51 are joined by a dovetail joint. The dovetail joint structure possesses excellent tensile and compressive strength and high connection strength. Using a dovetail joint as the fitting form for the slot 42 and the locking block 51 further enhances the connection strength and stability between the first adjusting seat 4 and the second adjusting seat 5, effectively resisting various external forces that may occur during adjustment, ensuring the structural stability and reliability of the foot cover during long-term use, and contributing to improving the overall quality and stability of the furniture. Of course, in other embodiments, the slot 42 can also be a T-slot or other shaped groove structure that restricts the locking block 51 from disengaging along the z-axis.
[0033] As a preferred embodiment, the ends of the front-to-back adjusting lever 7, the left-to-right adjusting lever 8, and the up-to-down adjusting lever 9 are all equipped with hexagonal sockets. The hexagonal socket design facilitates operation of the adjusting levers using tools such as hexagonal wrenches, making adjustment more effortless and convenient, and providing more precise control over the adjustment force. The hexagonal socket structure is relatively compact, not occupying excessive space, while ensuring a good fit between the tool and the adjusting lever, improving the reliability and stability of the adjustment.
[0034] As a preferred embodiment, the lower leg cover 2 houses the second adjustment seat 5 and the third adjustment seat 6. The lower leg cover 2 is fixed to the second adjustment seat 5 by connecting screws, and the second adjustment seat 5 is fixed to the third adjustment seat 6 by connecting screws. By designing the lower leg cover 2 to house the second adjustment seat 5 and the third adjustment seat 6, a relatively stable overall structure is formed between the lower leg cover 2, the second adjustment seat 5, and the third adjustment seat 6, enhancing the overall structural strength and stability of the leg cover. The indirect fixation between the lower leg cover 2 and the third adjustment seat 6 via the second adjustment seat 5 better disperses and transmits forces, reducing local stress concentration, thereby improving the load-bearing capacity and service life of the leg cover. It also helps ensure the stability and reliability of the leg cover during adjustment, ensuring the stability and safety of the furniture after installation.
[0035] As a preferred embodiment, the third adjustment seat 6 includes a box body 61 and a cover body 62. The box body 61 has a cavity for mounting the upper and lower adjustment rods 9 and the worm gear 101, with an opening at the top. The cover body 62 covers the opening of the box body 61 and has an opening for the transmission screw 10 to extend out. This split-type design of the third adjustment seat 6 facilitates the installation and maintenance of components such as the upper and lower adjustment rods 9 and the worm gear 101, improving the assembly efficiency and maintainability of the foot cover. In actual production, the box body 61 and the cover body 62 can be processed and assembled separately, reducing processing difficulty and cost. Furthermore, when internal components need repair or replacement, the cover can be quickly opened for operation without disassembling the entire foot cover, greatly improving maintenance efficiency, reducing maintenance costs and time, increasing the service life and economy of the foot cover, and also providing convenient conditions for future upgrades and improvements to the foot cover.
[0036] As a preferred embodiment, the base 1, upper foot sleeve 3, and lower foot sleeve 2 have square cross-sections. The square cross-sectional structure offers better stability and load-bearing capacity, better adapting to the structural characteristics of the furniture's bottom. Furthermore, it allows the first adjusting seat 4 and upper foot sleeve 3, driven by a lead screw, to move along the inner wall of the square structure without requiring additional limiting or guiding structures. Of course, in other embodiments, the cross-sections of the base 1, upper foot sleeve 3, and lower foot sleeve 2 can also be triangular or other non-circular shapes, or circular with additional limiting or guiding structures, depending on the specific requirements.
[0037] As a preferred embodiment, the base 1, lower foot cover 2, upper foot cover 3, first adjustment seat 4, second adjustment seat 5, and third adjustment seat 6 are all made of metal. Metal materials have high strength, high rigidity, and good wear resistance, which can ensure the stability and durability of the overall foot cover structure, extend the service life of the foot cover, reduce the replacement frequency, and improve the economy and reliability of the foot cover.
