Description

Technical Field

[0001] This utility model relates to the field of furniture installation technology, specifically a height-adjustable foot for a cabinet. Background Technology

[0002] In modern homes and offices, cabinets are essential storage furniture. Due to uneven floor surfaces, or to ensure multiple cabinets are installed side-by-side with level tops, adjustable feet are typically installed at the bottom of the cabinets. These feet extend and retract to adjust the height of the four corners of the cabinet from the ground, allowing for horizontal placement. Currently, cabinet height adjustment is achieved by rotating a foot plate at the bottom of the adjustable foot, or by rotating the entire foot. When adjusting the cabinet height, the operator must tilt and lift the heavy cabinet, or even bend over or lie on the ground to reach under the cabinet to rotate the foot plate or support rod. This is extremely time-consuming and laborious, especially with large, heavy cabinets or those already full of items, often requiring two people and offering very poor convenience. Furthermore, the repeated lifting and lowering of the cabinet poses a risk of injury to the operator or scratches to the floor.

[0003] Secondly, in existing technologies, the core connection point of the adjustable feet and the main load-bearing component are the side panels of the cabinet, and the weight of the entire cabinet is transferred through the connectors of the adjustable feet. However, the connection area between this connector and the side panel is relatively small, causing the enormous weight of the cabinet to be highly concentrated in a narrow area at the bottom of the side panel, creating stress concentration. Under long-term load, the board material in this stress concentration area is prone to permanent deformation, internal structural cracking, or even localized damage. This not only leads to loosening of connecting screws and failure of the adjustable feet, but more seriously, it directly damages the main structure of the cabinet, greatly affecting its stability and overall service life.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. A height-adjustable foot for a cabinet includes a support foot 2, a base plate 1 resting on the support foot 2, an inner support seat 21 on one side of the support foot 2 extending into the side plate 11; a base 3 is installed below the support foot 2, the base 3 protruding from the bottom end face of the support foot 2 and contacting the ground; a height adjustment mechanism 7 is provided between the support foot 2 and the base 3, rotating the height adjustment mechanism 7 causes the support foot 2 to move along the axis of the base 3, thereby realizing the height adjustment of the cabinet; it also includes a fastener 4 installed on the support foot 2, the fastener 4 being pre-embedded in the base plate 1; a locking nut 5 is connected inside the support foot 2, the fastener 4 is fitted over the locking nut 5, and the fastener 4 is fixed to the top of the support foot 2.

[0025] like Figure 1 , Figure 2As shown, unlike traditional cabinets where the load is concentrated on the side panels, in this design, the cabinet base rests on support legs. An inner support base is designed into the support legs to assist in the connection with the side panels, enhancing the stability of the connection. Fasteners are pre-embedded in the bottom of the base, and locking nuts are installed in the support legs to connect with these fasteners. The screw-on connection between the fasteners and locking nuts ensures that the entire base rests on top of the support legs, cleverly transferring the entire weight of the cabinet from the traditional side panels to the larger, more stable base. This fundamentally avoids problems such as deformation, cracking, or even damage to the side panels after long-term use due to stress concentration, significantly improving the structural stability and lifespan of the cabinet.

[0026] Secondly, a height adjustment mechanism is provided between the support legs and the base. Users can rotate the height adjustment mechanism to move the support legs axially up and down relative to the base, thereby achieving the purpose of adjusting the overall height of the cabinet.

[0027] A mounting cavity 24 is provided through the middle of the support leg 2. The locking nut 5 is connected to the top of the mounting cavity 24 and extends upward to connect with the fastener 4. Figure 3 As shown: A mounting cavity is provided through the body at the center of the support foot. This mounting cavity provides a certain space for the locking nut. The complex structure is concentrated in the mounting cavity, making the entire adjusting foot look neat and compact. It effectively protects the internal components from external dust and other corrosion, ensuring the long-term stable and reliable operation of the adjusting foot.

[0028] The height adjustment mechanism 7 includes an adjusting nut 71 fixed to the bottom of the mounting cavity 24, and an adjusting screw 72 installed inside the adjusting nut 71. The lower end of the adjusting screw 72 extends downward and is supported on the base 3.

[0029] like Figure 3 As shown: An adjusting nut is fixedly connected to the bottom of the mounting cavity, and an adjusting screw is installed inside the adjusting nut. To maintain the stability of the adjusting screw, its lower end extends downwards and is supported on the base as a fulcrum. When the adjusting screw rotates, since the adjusting nut is fixedly connected to the bottom of the support foot, the rotation of the adjusting screw forces the adjusting nut and the entire support foot to move axially up and down together, converting the rotational motion of the adjusting screw into the linear motion of the support foot. The structure is clear and the transmission is reliable.

[0030] The top of the adjusting screw 72 is recessed to form an adjusting hole 721. A clearance groove 6 is provided through the fastener 4 and the locking nut 5. The adjusting hole 721 and the clearance groove 6 are electrically connected. The adjusting tool 10 passes sequentially through the clearance groove 6 of the fastener 4 and the clearance groove 6 of the locking nut 5, and connects to the adjusting hole 721, driving the adjusting screw 72 to rotate. Figure 3, Figure 4 As shown: An adjustment hole is recessed at the top of the adjustment screw; corresponding to the adjustment hole, a clearance groove is also provided in the fastener and locking nut, which is connected to the adjustment hole. The design of the clearance groove and the adjustment hole forms a through channel from the inside of the cabinet, through the bottom plate, and directly to the top of the adjustment screw. When the user needs to adjust the cabinet height, the adjustment screw can be easily rotated by passing an adjustment tool through this through channel, thus achieving precise adjustment of the cabinet height. When adjusting the cabinet height, the user does not need to laboriously tilt or lift the heavy cabinet, nor does he / she need to bend over the narrow cabinet bottom. He / she simply opens the cabinet door, passes the adjustment tool through the through channel, connects it to the adjustment hole, and rotates the adjustment tool to drive the adjustment screw, achieving precise raising and lowering of the support legs. The "top-mounted" adjustment method makes the whole process time-saving and labor-saving, which can be easily completed by one person. It not only greatly improves the efficiency of installation and adjustment, but also avoids the safety risks that may be caused by lifting heavy objects, making it safe and convenient.

[0031] The bottom of the adjusting screw 72 extends out and is provided with a limiting platform 722. The base 3 has a limiting hole 31, and the limiting platform 722 is rotatably installed in the limiting hole 31.

[0032] like Figure 3 As shown: In order to further restrict the support point of the adjusting screw, a limiting platform is provided extending from the bottom of the adjusting screw. At the same time, a limiting hole is provided in the base for mounting the limiting platform. The limiting platform can and can only rotate within the limiting hole, restricting the axial displacement of the adjusting screw, providing stable support for the rotation of the adjusting screw, and ensuring the stability and smoothness of the adjustment process.

[0033] The outer cylindrical surface of the adjusting screw 72 is provided with an external threaded post 723, and correspondingly, the inner wall of the adjusting nut 71 is provided with an internal threaded hole 711, and the external threaded post 723 is screwed into the internal threaded hole 711.

[0034] like Figure 3 , Figure 4 As shown: The outer cylindrical surface of the adjusting screw is provided with an external thread post. In order to adapt to the assembly of the adjusting screw, an internal thread hole is provided on the inner wall of the adjusting nut. The adjusting screw and the adjusting nut are transmitted through the thread, which efficiently and accurately converts the rotational motion into linear motion, resulting in high adjustment accuracy. Moreover, the thread structure has self-locking properties, so it will not easily slip after being adjusted to the specified height, thus ensuring the stability of the cabinet height.

[0035] A connecting rod 8 is horizontally mounted on the fastener 4. One end of the connecting rod 8 is pre-embedded in the base plate 1, and the other end extends out of the side of the base plate 1 and connects to the side plate 11. The clearance groove 6 is provided through the connecting rod 8. Figure 3 , Figure 4As shown: The design of the connecting rod rigidly connects the base plate and the side plate into one unit, enhancing the connection stability of the cabinet, effectively preventing the cabinet structure from loosening, and extending the overall service life of the cabinet.

[0036] A guide groove 25 is hollowed out between the mounting cavity 24 and the body of the support foot 2. An insert plate 32 is provided on the outer periphery of the base 3. The insert plate 32 is inserted into the guide groove 25. The support foot 2 moves up and down along the axis of the insert plate 32.

[0037] like Figure 3 , Figure 5 As shown: A guide groove is set inside the support foot, and an insert plate is set in the base body. The insert plate and the guide groove are connected to form an anti-rotation mechanism, which effectively guides the axial movement of the support foot, ensuring that the support foot moves on the preset movement trajectory. The adjustment accuracy is high, avoiding the ineffective rotation of the adjusting screw during the rotation process, ensuring that the height adjustment function can be realized smoothly, and the adjustment process is more accurate and reliable.

[0038] The other side of the support leg 2 is provided with an outer support seat 22, the outer support seat 22 protrudes to form a positioning platform 23, the bottom of the base plate 1 is provided with a positioning hole, and the positioning platform 23 is connected in the positioning hole to restrict the lateral displacement of the base plate 1.

[0039] like Figure 3 , Figure 4 , Figure 5 As shown: An external support base is set on the support leg, and a positioning platform is designed on the external support base. The positioning platform is used to connect with the positioning hole on the bottom of the base plate to accurately position the support leg and the base plate in the lateral direction. This effectively limits the lateral displacement of the base plate, enhances the cabinet's resistance to torsion and lateral thrust, effectively solves the problem of loose connection of traditional cabinet legs and easy shaking of the cabinet, and improves the overall stability.

[0040] In summary: During use, the user first embeds and fixes the fasteners and their connecting rods within the base plate, simultaneously connecting them to the side plates. Next, the positioning plates on the support legs are precisely inserted into the positioning holes in the base plate, thus initially connecting the support legs to the fasteners. At this point, by cooperating with the locking nuts and fasteners, the base plate and side plates are connected as a single unit via the support legs. At this point, the main load-bearing capacity of the cabinet shifts from the traditional side plates to the more structurally stable base plate.

[0041] When the cabinet height needs to be adjusted, the user does not need to move or tilt the cabinet. Simply insert an adjusting tool from inside the cabinet, passing it through the clearance groove located in the center of the fastener and locking nut, and align it with the adjusting hole of the adjusting screw inside the support leg. The user rotates the adjusting tool, and the adjusting screw rotates accordingly. Because the bottom of the adjusting screw is fixed in the limiting hole of the base by the limiting platform, and the support leg body is constrained by the cooperation of the guide groove and the insert plate, the rotational motion of the adjusting screw is precisely converted into the linear motion of the support leg. This forces the support leg to move smoothly and steadily up and down along the axis of the base, thus accurately adjusting the cabinet height. The adjustment process is simple, convenient, time-saving, labor-saving, efficient, and safe, and therefore can be widely used.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
