Description

Technical Field

[0001] This utility model relates to the field of cabinet furniture installation technology, and in particular to a height adjustment structure for a floor-standing cabinet. Background Technology

[0002] In the field of cabinet furniture, floor-standing products such as sideboards, dining cabinets, TV cabinets, and storage cabinets often feature a base that rests directly on the ground, a common and practical structural form. This design provides good overall stability, appears visually solid and reliable, and helps distribute the weight of the cabinet and the items it supports. However, this structure has a significant drawback in actual installation and use: it requires extremely high installation precision and lacks effective error tolerance and adjustment mechanisms.

[0003] Since cabinets are typically assembled from multiple vertical panels, partitions, and a base plate using connectors, minor misalignment errors can occur during factory production or on-site installation due to factors such as the verticality of the vertical panels, the flatness of the connection between the base plate and the vertical panels, and the levelness of the ground itself. When these minor errors accumulate or are amplified individually, they can cause a slight tilt or twisting of the overall cabinet frame, resulting in instability and wobbling. Because the base plate is the load-bearing surface in direct contact with the ground, if the frame tilts due to errors, the entire weight of the cabinet will be directly pressed onto the uneven support points through the tilted base plate.

[0004] Therefore, we sought to design a structure that facilitates height adjustment for floor-standing cabinet products. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a height-adjustable structure for a floor-standing cabinet.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a height adjustment structure for a floor cabinet, including: a base plate, an adjustment seat and adjustment screws;

[0007] The bottom plate has an insertion hole on its lower side; the adjusting seat has an insertion block, which is inserted into the insertion hole; the insertion block has a threaded inner hole; the adjusting screw is threaded into the threaded inner hole from below and rests against the ground from below; the bottom plate has an adjusting through hole that runs vertically through it; the adjusting through hole is located above the threaded inner hole.

[0008] Optionally, the top of the adjusting screw is provided with a countersunk hexagonal socket; the countersunk hexagonal socket is located below the adjusting through hole.

[0009] Optionally, the bottom of the adjusting screw has a flat end.

[0010] Optionally, the end is disc-shaped.

[0011] Optionally, the end cap is fitted with a scratch-resistant cover.

[0012] Optionally, the adjustment seat includes a support plate; the support plate is located below the mounting block and is attached to the lower side of the base plate.

[0013] Optionally, the support plate has a clearance groove located below the mounting block; the end of the adjusting screw can be recessed into the clearance groove.

[0014] Optionally, the lower edge of the adjustment through hole is provided with several buffer ribs along the circumferential direction.

[0015] Optionally, the outer wall of the insert block is provided with a vertically extending protruding rib.

[0016] Optionally, the adjusting seat is made of zinc alloy; the adjusting screw is a carbon steel screw.

[0017] The beneficial effects of this utility model are as follows: By setting an adjusting seat embedded in the mounting hole of the base plate and an adjusting screw that is threaded into it, the length of the adjusting screw extending from the lower end of the adjusting seat can be precisely and conveniently changed by rotating the adjusting screw, thereby achieving independent fine-tuning of the height of the corresponding corner points of the cabinet. There is no need to lift or move the heavy cabinet; simply operate the adjusting screw through the adjusting hole on the base plate with a tool to easily compensate for installation errors or tilting caused by uneven ground, effectively solving problems such as cabinet wobbling and uneven door gaps. The adjustment operation can be completed with only conventional tools (such as a screwdriver or hex wrench) through the adjusting hole, which is simple and intuitive. If the ground changes or readjustment is needed later, it can be easily performed at any time, providing good maintainability.

[0029] Example

[0030] Reference Figures 1 to 3 The present invention proposes a height adjustment structure for a floor cabinet, comprising: a base plate 10, an adjustment seat 20, and an adjustment screw 30;

[0031] The base plate 10 has an insertion hole 11 on its lower side; the adjusting seat 20 has an insertion block 21, which is inserted into the insertion hole 11; the insertion block 21 has a threaded inner hole 22; the adjusting screw 30 is threadedly connected to the threaded inner hole 22 from below and rests against the ground below; the base plate 10 has an adjusting through hole 12 that runs vertically through it; the adjusting through hole 12 is located above the threaded inner hole 22.

[0032] In this invention, by setting an adjusting seat 20 embedded in the mounting hole 11 of the base plate 10 and an adjusting screw 30 threadedly engaged therewith, the length of the adjusting screw 30 extending from the lower end of the adjusting seat 20 can be precisely and conveniently changed by rotating the adjusting screw 30, thereby achieving independent fine-tuning of the height of the corresponding corner points of the cabinet. There is no need to lift or move the heavy cabinet; simply operate the adjusting screw 30 through the adjusting through hole 12 on the base plate 10 with a tool to easily compensate for installation errors or tilting caused by uneven ground, effectively solving problems such as cabinet wobbling and uneven door gaps. The adjustment operation only requires conventional tools (such as a screwdriver or hex wrench) through the adjusting through hole 12, making it simple and intuitive. If the ground changes later or readjustment is needed, it can be easily performed at any time, providing good maintainability.

[0033] In this embodiment, the top of the adjusting screw 30 is provided with a countersunk hexagonal socket 31; the countersunk hexagonal socket 31 is located below the adjusting through hole 12. This allows the use of a hexagonal wrench from inside the cabinet through the adjusting through hole 12, avoiding collisions between the tool and the base plate 10, and making operation convenient.

[0034] In this embodiment, the bottom of the adjusting screw 30 is provided with a flat end 32. The flat end 32 design can increase the grounding area, disperse the pressure, and prevent damage to the wooden floor or tile.

[0035] Specifically, the end 32 is disc-shaped, which can further optimize the pressure distribution and avoid local stress concentration when tilted.

[0036] In this embodiment, the end 32 is fitted with a scratch-resistant cover 40. The scratch-resistant cover 40, formed of plastic, rubber, or silicone, can eliminate hard contact between the metal and the ground, providing anti-slip and shock absorption.

[0037] In this embodiment, the adjustment seat 20 includes a support plate 23; the support plate 23 is located below the mounting block 21 and is attached to the lower side of the base plate 10. The support plate 23 increases the contact area between the adjustment seat 20 and the base plate 10, preventing local deformation and improving load-bearing capacity.

[0038] Specifically, the support plate 23 has a clearance groove 24 located below the mounting block 21; the end 32 below the adjusting screw 30 can be inserted into the clearance groove 24. The clearance groove 24 structure allows the end 32 to be inserted into the groove when the adjusting screw 30 is fully screwed in, achieving "zero protrusion height" and ensuring the minimum installation height of the cabinet.

[0039] In this embodiment, a plurality of buffer ribs 25 are provided circumferentially along the lower edge of the adjusting through hole 12. When the adjusting screw 30 is almost tightened to the top, the buffer ribs 25 can prevent the adjusting screw 30 from moving further upward, thus avoiding direct friction between the adjusting screw 30 and the adjusting seat 20.

[0040] In this embodiment, the outer wall of the insert block 21 is provided with a vertically extending protruding rib 26. The vertical rib and the insert hole 11 form an interference fit, ensuring the reliability of structural adjustments during long-term use, especially in handling vibration scenarios.

[0041] In this embodiment, the adjusting seat 20 is made of zinc alloy; the adjusting screw 30 is a carbon steel screw. The zinc alloy die-casting process ensures the strength and corrosion resistance of the adjusting seat 20; the carbon steel screw is nickel-plated to provide high thread wear resistance.

[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
