Description

Technical Field

[0001] The utility model relates to the technical field of adjusting feet, in particular to an adjusting foot for furniture. Background Art

[0002] In furniture products, especially in integrated wardrobes, there is basically no function of horizontal adjustment for uneven ground, and the problem of uneven ground in buildings is a common phenomenon. Since integrated wardrobes are usually assembled with wooden boards, they are large in size and have poor overall rigidity. When the ground is uneven or the wall is not perpendicular to the ground, the wardrobe will deform with the uneven ground, resulting in problems such as being unable to be leveled with the wall or the wardrobe door being unable to be closed tightly, which affects both the appearance and the use. In order to solve this problem, people used to use wedge-shaped pads to raise the wardrobe at a lower part of the ground. If one of the four corners of the wardrobe is lower than the ground, only one corner needs to be padded. When one of the four corners of the wardrobe is higher than the ground, the other three corners need to be padded. However, it is difficult to construct the part close to the wall corner, especially when the wall is not perpendicular to the ground. In order to make the back or side of the wardrobe level with the wall, more parts need to be padded, which is very troublesome to operate, and the pads exposed outside also affect the appearance.

[0003] In order to solve the above problems, existing cabinets are equipped with adjustment feet at the bottom to adjust the level and height of the cabinet. However, the existing adjustment feet require machining through holes on the bottom plate of the cabinet, and then use tools to insert the adjustment feet through the through holes of the bottom plate, and screw the foot nails to adjust the level and height of the cabinet. After the cabinet bottom plate is punched, in order not to affect its aesthetics, a decorative cover needs to be set at the position of the machining through hole on the cabinet bottom plate.

[0026] In order to better understand the purpose, function and specific design of the present invention, the furniture adjusting foot of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-Figure 6 As shown, the furniture adjustment foot of the utility model comprises a housing 1 and a foot nail 2, and a through hole 122 for the foot nail 2 to pass through is provided at the bottom of the housing 1. An adjustment component is provided inside the housing 1, and the adjustment component is sleeved on the foot nail 2. The adjustment component comprises a first bevel gear 7 and a second bevel gear 4 that are meshed and connected. A nut bushing 8 is fixed inside the first bevel gear 7, and an inner wall of the nut bushing 8 is provided with an inner thread 83. An outer thread 22 that matches the inner thread 83 of the nut bushing 8 is provided on the outer wall of the foot nail 2. The foot nail 2 is threadedly connected with the nut bushing 8, and the second bevel gear 4 is driven to drive the first bevel gear 7 to rotate, so that the foot nail 2 can move up and down relative to the housing 1, so as to change the distance between the housing 1 and the foot nail 2 to adjust the overall height.

[0028] When driving the second bevel gear 4 to rotate, in order to prevent the foot nail 2 from rotating with the first bevel gear 7, positioning surfaces 23 are provided on opposite sides of the foot nail 2, and matching surfaces 1221 abutting against the positioning surfaces 23 are provided on opposite sides of the through hole 122 of the shell 1, and the matching surfaces 1221 are tightly against the positioning surfaces 23.

[0029] like Figure 3-Figure 5 As shown, the housing 1 is composed of an upper housing 11 and a lower housing 12, one end of the lower housing 12 is provided with a fixing seat 121, the fixing seat 121 is provided with a slot 1211, one end of the upper housing 11 is provided with a plug-in 111 adapted to the slot 1211, one end of the upper housing 11 is connected to the lower housing 12 through the plug-in 111, and the other end of the upper housing 11 is connected to the lower housing 12 through a fastener 9. The fastener 9 of this embodiment can be a rivet or a screw.

[0030] The inner wall of the port 14 of the housing 1 is provided with a first annular groove 15 and a second annular groove 16. The annular protrusion 41 of the second bevel gear 4 is placed in the first annular groove 15 and can rotate relative to the first annular groove 15. At the same time, the second bevel gear 4 can be prevented from shifting. An inner hexagonal hole 42 for connecting a hexagonal wrench is provided at one end of the second bevel gear 4. A clip 6 is installed in the second annular groove 16. The clip 6 is used to clamp the hexagonal wrench to prevent the hexagonal wrench from escaping from the inner hexagonal hole 42 of the second bevel gear 4.

[0031] like Figure 3 , Figure 5 and Figure 8 As shown, the inner wall of the first bevel gear 7 is provided with a slotted hole 71, the outer wall of the nut bushing 8 is provided with a protrusion 84 matched with the slotted hole 71 of the first bevel gear 7, and the nut bushing 8 is fixed inside the first bevel gear 7 through the protrusion 84. The bottom of the nut bushing 8 is provided with a base 81, which contacts the step surface 73 of the first bevel gear 7, and the top of the nut bushing 8 is provided with a buckle 82, which contacts the retaining edge 72 of the first bevel gear 7. When the nut bushing 8 needs to be replaced, the buckle 82 is compressed, and the nut bushing 8 is moved downward to make the nut bushing 8 disengage from the first bevel gear 7.

[0032] like Figure 5 and Figure 6 As shown, convex columns 112 are provided on both sides of the upper shell 11, so that the shell is in a butterfly shape as a whole, and the upper surface of the convex column 112 is a flat design. Deep nail holes 1121 are provided on the convex column 112, and the adjustment feet are fixed to the bottom of the cabinet using self-tapping screws to ensure the directionality and stability of the adjustment feet, and also prevent them from tilting due to load-bearing.

[0033] like Figure 1 , Figure 5 , Figure 6 and Fig. 9 As shown, the furniture adjusting foot further comprises a guide member 3 , which is fixed at the port 14 of the housing 1 , so as to facilitate a hexagonal wrench to extend into the inner hexagonal hole 42 of the second bevel gear 4 .

[0034] The upper and lower sides of the shell port 14 are both provided with card slots 13 , and one end of the guide member 3 is provided with a card block 31 matched with the card slot 13 . The guide member 3 is connected and fixed to the shell 1 through the card block 31 .

[0035] A foot pad 5 is provided at the bottom of the foot nail 2, and a boss 51 is provided in the middle of the foot pad 5. The foot pad 5 is inserted into the bottom of the foot nail 2 through the boss 51. The foot pad 5 is made of plastic material to prevent the foot nail 2 from scratching the ground when the furniture is moved.

[0036] A boss 113 is disposed at the upper end of the upper shell 11 , and the boss 113 is embedded in a corresponding blind hole of the cabinet bottom plate to play a role of limiting and positioning.

[0037] like Figure 7 As shown, during installation, the self-tapping screws pass through the deep nail holes 1121 of the shell to fix the adjusting feet at the bottom of the cabinet. The adjusting feet located in the front of the cabinet do not need to be installed with guide pieces. When the height of the furniture needs to be adjusted, the hexagonal wrench is inserted into the hexagonal hole 42 of the second bevel gear 4. By rotating the hexagonal wrench, the second bevel gear 4 drives the first bevel gear 7 to rotate, so that the foot nail 2 can move up and down relative to the shell 1, thereby changing the distance between the shell 1 and the foot nail 2 to adjust the overall height.

[0038] The overall shape of the adjusting foot is a butterfly-shaped structure design. The adjusting foot has a certain inclination when installed, so that the adjusting foot behind the cabinet avoids the shielding of the adjusting foot in front, which facilitates the extended hexagonal wrench to be smoothly inserted into the inner hexagonal hole 42 of the second bevel gear 4 through the guide piece (such as Figure 7 as shown).

[0039] There are convex columns on the left and right sides of the adjusting foot, and the upper surface of the convex column is a flat design. When the adjusting foot is used on a floor-standing vertical plate, the convex column can be embedded in the corresponding hole of the vertical plate with the same diameter to play a limiting and supporting role (such as Figure 7 As shown), when used on a vertical plate that does not touch the ground, the convex column is flush with the bottom plate, and the upper plane of the convex column supports the vertical plate and also plays a role of limiting and supporting.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
