Description

Technical Field

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

[0002] Existing technology for cabinet feet typically includes separate foot panels, adjustable feet (plastic or metal), and connectors, resulting in an overall larger structural size and cumbersome adjustment operations. Especially when furniture is placed against a wall, the feet closest to the wall are difficult to adjust due to obstruction. In addition, exposed hardware after connection and large required assembly holes also affect aesthetics, and existing connectors have a single function and do not have the additional attribute of connecting cabinet panels.

[0003] Existing foot anchors are usually adjusted for height via threaded connections, but the relative rotation between the foot anchor and the base can easily scratch the ground. Utility Model Content

[0004] The purpose of this invention is to provide a cabinet adjustable foot that can prevent scratching the floor when adjusting the height.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution: An adjustable cabinet foot includes a high-strength adjusting nut and a high-strength base on the bottom surface of the cabinet base plate. The high-strength adjusting nut includes a stud and a head at the bottom of the stud, the outer diameter of the head being larger than the outer diameter of the stud. The top of the stud has a recessed groove that matches the shape of a screwdriver or wrench tip. The high-strength base has a threaded hole for threaded connection with the stud. A plastic anti-scratch sleeve is fitted over the head. When the stud is screwed into the threaded hole, the bottom end of the plastic anti-scratch sleeve is located below the bottom end of the high-strength base. Both the high-strength adjusting nut and the high-strength base are made of zinc alloy or other high-strength materials. Their functions are as follows: the high-strength base fixes the adjustable cabinet foot to the bottom surface of the cabinet, providing a support reference; the recessed groove allows the high-strength adjusting nut to be turned by inserting a screwdriver or wrench into the recessed groove, adjusting its depth within the high-strength base, thereby adjusting the cabinet height; the plastic anti-scratch sleeve prevents the high-strength adjusting nut from scratching the floor during rotation.

[0006] Furthermore, the plastic anti-scratch sleeve has a placement cavity with an open top, and a limiting plate is provided at the top of the inner wall of the placement cavity. Its function is to accommodate the head of the high-strength adjusting nut by setting the placement cavity, so that the high-strength adjusting nut can rotate relative to the plastic anti-scratch sleeve; and to prevent the high-strength adjusting nut from falling out of the placement cavity by setting the limiting plate.

[0007] Furthermore, a through groove is provided on the bottom end of the plastic anti-scratch sleeve in the area corresponding to the limiting plate. The function of this through groove is to provide space for the plastic anti-scratch sleeve to elastically deform, facilitating the installation of the high-strength adjusting nut and the plastic anti-scratch sleeve.

[0008] Furthermore, the outer edge of the plastic anti-scratch sleeve has a notch in the area corresponding to the limiting plate. This notch provides additional space for elastic deformation.

[0009] Furthermore, the top of the limiting plate is chamfered towards the center of the placement cavity. This chamfer facilitates pressing the head down to deform the limiting plate outwards. Once the head has completely passed the limiting plate, the plate springs back and blocks the top of the head, thus securing it in place.

[0010] Furthermore, the high-strength adjusting nut has a blind hole at its bottom end, and a boss for embedding into the blind hole is located at the bottom end of the placement cavity. The outer diameter of the boss is the same as the inner diameter of the blind hole. Both the blind hole and the boss are cylindrical, with their heads coaxial with the stud, and the boss coaxial with the plastic anti-scratch sleeve. Their function is to prevent translation between the plastic anti-scratch sleeve and the high-strength adjusting nut, while also preventing the plastic anti-scratch sleeve from rotating with the nut, thus preventing it from scratching the floor.

[0011] Furthermore, the top of the high-strength base is flat, and the bottom is sloped. This design ensures that the flat top of the high-strength base fits snugly against the bottom surface of the cabinet; the sloped bottom allows it to adapt to uneven surfaces.

[0012] Furthermore, the high-strength base is provided with two connecting holes that penetrate both the top and bottom surfaces. A stepped hole is provided at the bottom end of each connecting hole, with the inner diameter of the stepped hole being larger than that of the connecting hole. This design allows screws to pass through the connecting holes and press against the end face of the stepped hole, thereby fixing the high-strength base to the bottom surface of the cabinet base plate.

[0013] Furthermore, it also includes a connecting rod for embedding into the cabinet side panel and a sleeve for embedding into the top surface of the cabinet bottom plate. The sleeve has a sleeve hole coaxially arranged through it. The connecting rod is perpendicular to the sleeve and penetrates through it. The stud is coaxially arranged with the sleeve. The connecting rod has a through hole on its side wall. A set screw is internally threaded at the top of the sleeve. The set screw has a set screw hole coaxially arranged through it. With the set screw pressing the connecting rod into the sleeve, the set screw hole, through hole, sleeve hole, and base groove are coaxially arranged. Its function is to connect the cabinet side panel and the cabinet bottom plate through the connecting rod, sleeve, and set screw; and to allow a screwdriver or wrench to be inserted through the holes to rotate the high-strength adjusting nut, thereby adjusting the height.

[0014] Furthermore, it includes a pre-embedded nut for embedding in the side panel, and the connecting rod has an external thread for threaded connection with the pre-embedded nut. The end of the connecting rod away from the external thread has a countersunk groove that matches the shape of the screwdriver or wrench tip. Its function is to enable quick assembly and disassembly of the connecting rod from the cabinet side panel through the pre-embedded nut and external thread.

[0015] The beneficial effects of this utility model are: 1. The high-strength base secures the cabinet's adjustable feet to the bottom of the cabinet, providing a support reference. The high-strength adjusting nut and recessed foot groove allow for adjustment of the cabinet's height by turning the nut within the high-strength base using a screwdriver or wrench. The plastic anti-scratch sleeve prevents the high-strength adjusting nut from scratching the floor during rotation.

[0016] 2. The placement cavity can accommodate the head of the high-strength adjusting nut, allowing the high-strength adjusting nut to rotate relative to the plastic anti-scratch sleeve; the limiting plate can prevent the high-strength adjusting nut from falling out of the placement cavity.

[0022] Example 1 A type of cabinet adjustable feet, such as Figure 1As shown, it includes a high-strength adjusting nut 1 and a high-strength base 2 located on the bottom surface of the cabinet base plate 26. The high-strength adjusting nut 1 includes a stud 3 and a head 4 located at the bottom end of the stud 3. The outer diameter of the head 4 is larger than the outer diameter of the stud 3. The top end of the stud 3 is provided with a recessed groove 5 that matches the shape of the top of a screwdriver or wrench. The high-strength base 2 is provided with a threaded hole 6 for threaded connection with the stud 3. The head 4 is covered with a plastic anti-scratch sleeve 7. When the stud 3 is screwed into the threaded hole 6, the bottom end of the plastic anti-scratch sleeve 7 is located below the bottom end of the high-strength base 2. Its function is as follows: by setting the high-strength base 2, the cabinet adjustment feet can be fixed to the bottom of the cabinet, providing a support reference; by setting the high-strength adjustment nut 1 and the foot recess 5, the depth of the high-strength adjustment nut 1 in the high-strength base 2 can be adjusted by inserting a screwdriver or wrench into the foot recess 5 and turning it; and by setting the plastic anti-scratch sleeve 7, the floor can be prevented from being scratched when the high-strength adjustment nut 1 is rotated.

[0023] Specifically, such as Figure 1 As shown, the plastic anti-scratch sleeve 7 has a placement cavity 8 with an open top, and a limiting plate 9 is provided at the top of the inner wall of the placement cavity 8. Its function is to accommodate the head 4 of the high-strength adjusting nut 1 through the placement cavity 8, so that the high-strength adjusting nut 1 can rotate relative to the plastic anti-scratch sleeve 7; and to prevent the high-strength adjusting nut 1 from falling out of the placement cavity 8 through the limiting plate 9.

[0024] Specifically, such as Figure 2 As shown, a through groove 10 is provided on the bottom end of the plastic anti-scratch sleeve 7 in the area corresponding to the limiting plate 9. Its function is to provide space for elastic deformation of the plastic anti-scratch sleeve 7 through the through groove 10, which facilitates the installation of the high-strength adjusting nut 1 and the plastic anti-scratch sleeve 7.

[0025] Specifically, such as Figure 2 As shown, the outer edge of the plastic anti-scratch sleeve 7 has a notch 11 in the area corresponding to the limiting plate 9. Its function is to provide space for elastic deformation through the setting of the notch 11.

[0026] Specifically, such as Figure 1 As shown, the top of the limiting plate 9 is chamfered towards the middle of the placement cavity 8. Its function is that, by setting the chamfer, it is easy to press down on the head 4 to deform the limiting plate 9 outward. After the head 4 has completely passed through the limiting plate 9, the limiting plate 9 springs back and covers the top of the head 4, thereby achieving the effect of fixing the head 4.

[0027] Specifically, such as Figure 2As shown, the high-strength adjusting nut 1 has a blind hole 12 at its bottom end, and a boss 13 for embedding into the blind hole 12 is provided at the bottom end of the placement cavity 8. The outer diameter of the boss 13 is the same as the inner diameter of the blind hole 12. Both the blind hole 12 and the boss 13 are cylindrical. The head 4 is coaxially arranged with the stud 3, the blind hole 12 is coaxially arranged with the head 4, and the boss 13 is coaxially arranged with the plastic anti-scratch sleeve 7. Its function is to prevent the plastic anti-scratch sleeve 7 from translating with the high-strength adjusting nut 1 through the setting of the blind hole 12 and the boss 13, and at the same time, to prevent the plastic anti-scratch sleeve 7 from rotating with the nut, thereby preventing the plastic anti-scratch sleeve 7 from scratching the floor.

[0028] Specifically, such as Figure 3 As shown, the top of the high-strength base 2 is flat, and the bottom of the high-strength base 2 is sloping. Its function is that the flat top of the high-strength base 2 ensures it can fit close to the bottom surface of the cabinet base plate 26; and the sloping bottom of the high-strength base 2 adapts to uneven ground.

[0029] Specifically, such as Figure 2 As shown, the high-strength base 2 has two through-holes 14 on its upper and lower surfaces. A stepped hole 15 is provided at the bottom end of each through-hole 14, and the inner diameter of the stepped hole 15 is larger than the inner diameter of the through-hole 14. The purpose of these holes is to allow screws to pass through the through-holes 14 and press against the end face of the stepped hole 15, thereby fixing the high-strength base 2 to the bottom surface of the cabinet base plate 26.

[0030] The working principle of this embodiment is explained as follows: First, screw the stud 3 into the threaded hole 6 (do not tighten it yet). Then, with the placement groove facing the head 4 and the screw facing away from the placement groove, push the head 4 into the placement groove from top to bottom. The chamfered top of the limiting plate 9 guides the head 4 to slide downward into the placement groove. After the head 4 pushes the limiting plate 9 outward, it enters the placement groove. When the head 4 is completely inside the placement groove, the limiting plate 9 is stopped at the top of the head 4 by elastic reset. At the same time as the head 4 enters the placement groove, the boss 13 enters the blind hole 12. Figure 3 As shown, the installation of the high-strength adjusting nut 1, the high-strength base 2, and the plastic anti-scratch sleeve 7 is completed.

[0031] When the cabinet height needs to be adjusted, simply insert a hex wrench into the base plate 26 through the coaxial through hole with the base groove 5 from top to bottom, and then turn the hex wrench to rotate the high-strength adjusting nut 1, thereby adjusting the cabinet height. During the rotation of the high-strength adjusting nut 1, the high-strength adjusting nut 1 and the plastic anti-scratch sleeve 7 rotate relative to each other, while the plastic anti-scratch sleeve 7 remains relatively stationary with respect to the ground, thus preventing scratches on the ground.

[0032] Example 2 like Figure 4As shown, based on Embodiment 1, it further includes a connecting rod 18 for embedding into the cabinet side panel 25 and a sleeve 16 for embedding into the top surface of the cabinet bottom panel 26. The sleeve 16 has a sleeve hole 17 coaxially arranged with the sleeve 16. The connecting rod 18 is perpendicular to the sleeve 16 and penetrates the sleeve 16. The stud 3 is coaxially arranged with the sleeve 16. The connecting rod 18 has a through hole 19 on its side wall. The top of the sleeve 16 is internally threaded with a set screw 20. The set screw 20 has a set screw hole 21 coaxially arranged with the set screw 20. When the set screw 20 presses the connecting rod 18 into the sleeve 16, the set screw hole 21, the through hole 19, the sleeve hole 17, and the base recess 5 are coaxially arranged. The recess 24 uses a cross hole, and the base recess 5 uses an internal hexagonal hole. Its function is to connect the cabinet side panel 25 and the cabinet bottom panel 26 through the setting of the connecting rod 18, sleeve 16 and set screw 20; through the setting of set screw hole 21, through hole 19 and sleeve hole 17, a screwdriver or wrench can be inserted through the above holes to drive the high-strength adjusting nut 1 to rotate, thereby achieving the function of adjusting the height.

[0033] Specifically, such as Figure 2 As shown, it also includes a pre-embedded nut 22 for embedding in the side plate 25, and an external thread 23 for threaded connection with the pre-embedded nut 22 on the connecting rod 18. A countersunk groove 24, adapted to the shape of the screwdriver or wrench tip, is provided on the end of the connecting rod 18 away from the external thread 23. Its function is to enable quick assembly and disassembly of the connecting rod 18 from the cabinet side plate 25 through the pre-embedded nut 22 and the external thread 23.

[0034] The remaining structure and principle are the same as in Example 1.

[0035] The working principle of this embodiment is explained as follows: After the installation of the high-strength adjusting nut 1, the high-strength base 2, and the plastic anti-scratch sleeve 7 is completed, the pre-embedded nut 22 is embedded into the cabinet side plate 25, the sleeve 16 is vertically embedded from top to bottom into the pre-drilled hole in the top surface of the cabinet bottom plate 26, the top of the high-strength base 2 with the high-strength adjusting nut 1 and the plastic anti-scratch sleeve 7 is pressed against the bottom surface of the cabinet bottom plate 26, the screw is inserted into the pre-drilled hole of the cabinet bottom plate 26, and the screw is passed through the connecting hole 14 and screwed into the cabinet bottom plate 26 from bottom to top until the screw head is pressed on the step hole 15; Next, use a screwdriver or wrench to insert into the countersunk groove 24 and screw the end of the connecting rod 18 with the external thread 23 into the pre-embedded nut 22. Then, extend the connecting post on the side plate 25 into the side hole of the base plate 26 so that the connecting post passes through the sleeve 16. Then, screw the set screw 20 into the top of the sleeve 16 to ensure that the set screw hole 21, the through hole 19, the sleeve hole 17, and the countersunk groove 5 are coaxially set, thus completing the connection of the adjusting foot to the side plate 25 and the base plate 26.

[0036] When the cabinet height needs to be adjusted, simply use a hex wrench to pass through the top screw hole 21, through hole 19, and sleeve hole 17 from top to bottom into the base groove 5. Then, turn the hex wrench to rotate the high-strength adjusting nut 1, thereby adjusting the cabinet height. During the rotation of the high-strength adjusting nut 1, the high-strength adjusting nut 1 and the plastic anti-scratch sleeve 7 rotate relative to each other, while the plastic anti-scratch sleeve 7 remains relatively stationary with respect to the ground, thus preventing scratches on the ground.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
