Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a wardrobe leveling foot. Background Technology

[0002] A wardrobe is a cabinet for storing clothes, usually made of engineered wood or natural wood panels, combined with hardware accessories. The standard structure of this type of wardrobe is a fixed panel wardrobe, which cannot be adjusted after assembly. Each storage compartment is fixed and cannot be adjusted according to the type of clothing.

[0003] In recent years, some metal wardrobes have emerged, assembled with stainless steel, aluminum alloy, tempered glass and other hardware accessories. These metal wardrobes use detachable columns and panels, which are indeed relatively environmentally friendly and allow for some adjustment of clothing storage space.

[0004] After the wardrobe is assembled, it needs to be leveled. Existing leveling mechanisms have the following problems:

[0005] 1. Because the adjustment components are relatively small, external adjustment tools are required for adjustment. Installers cannot adjust them manually by hand, or it is very difficult to do so.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a wardrobe leveling foot, comprising a first housing, a second housing, a leveling screw, and a screwing device; the first housing abuts against the lower end of the wardrobe to be leveled device, and rotating the screwing device can drive the leveling screw to rotate, thereby driving the first housing to rise and fall within the second housing, realizing the raising and lowering of the wardrobe to be leveled device.

[0010] In a preferred embodiment, the first housing has a first protrusion, and the wardrobe leveling device has a cavity. The first protrusion on the first housing extends into the cavity of the wardrobe leveling device, and the first protrusion has a guide slope. The first housing also has a pre-embedded nut, a second protrusion, and a third protrusion that are threadedly engaged with the leveling screw. The second housing has a first cavity and a second cavity that are respectively slidably engaged with the second protrusion and the third protrusion. When the screwing device is rotated, the leveling screw is driven to rotate. During the rotation of the leveling screw, it is threadedly engaged with the pre-embedded nut in the first housing, causing the first housing to rise and fall. During the rising and falling of the first housing, the second protrusion and the third protrusion of the first housing are respectively slidably engaged with the first cavity and the second cavity of the second housing, thereby guiding the rising and falling of the first housing.

[0011] In a preferred embodiment, the screwing device includes an adjusting nut rigidly connected to the leveling screw and a hand-tightening housing that engages with the adjusting nut. The wardrobe leveling feet also include a hollow decorative sliding cover, through which the leveling screw passes, and the decorative sliding cover rests freely on the hand-tightening housing. By rotating the hand-tightening housing, the adjusting nut drives the leveling screw to rotate as a whole. The leveling screw engages with a nut pre-embedded in the first housing, thereby raising and lowering the first housing. A spring is fitted on the leveling screw, with one end of the spring abutting against the inner shell of the decorative sliding cover and the other end abutting against the first housing, allowing the decorative sliding cover to follow the rise and fall. The decorative sliding cover ensures that the rise and fall of the first housing does not cause the leveling screw to be exposed.

During the rising and falling of the first housing 31, the second protrusion 312 and the third protrusion 313 of the first housing 31 are respectively slidably engaged with the first cavity 321 and the second cavity 322 of the second housing, thereby guiding the rising and falling of the first housing 31. The screwing device 34 includes an adjusting nut 341 that is rigidly connected to the leveling screw 33. (The rigid connection between the adjusting nut 341 and the leveling screw 33 can be achieved by installing the adjusting nut 341 onto the leveling screw 33 and then fixing it with glue or by welding, etc. In other embodiments, the leveling screw 33 can also have two nuts, one of which is the adjusting nut 341 and the other is a locking nut that matches the adjusting nut 341. The two nuts are fitted onto the leveling screw 33 to achieve locking. The three parts are integrated by gluing or welding. At the same time, the leveling screw 33 is installed on the second housing 32 so that it can rotate relative to the second housing 32 but will not fall off.)The wardrobe leveling feet 30 also include a hollow decorative sliding cover 35 through which the leveling screw 33 passes. The leveling screw 33 is threaded onto the pre-embedded nut 311 in the first housing 31, allowing the first housing 31 to be raised and lowered. A spring 331 is fitted on the leveling screw 33. One end of the spring 33 abuts against the inner shell of the decorative sliding cover 35, and the other end abuts against the first housing 31, allowing the decorative sliding cover 35 to follow the raising and lowering of the first housing 31. The decorative sliding cover 35 ensures that the raising and lowering of the first housing 31 will not cause the leveling screw 33 to be exposed. The wardrobe leveling feet 30 also include foot positioning pieces 36, which can be locked to the ground with self-tapping screws, and can be installed and fixed with the second housing 32 by thread engagement (of course, in other embodiments, the foot positioning pieces can also be fixed with the second housing by other fixing methods).

[0051] The quick-release connecting device 4 includes a quick-release buckle housing 41, two quick-release buckle steel hooks 42, a quick-release buckle eccentric lock 43, and a quick-release buckle shaft 44. The quick-release buckle eccentric lock 43 is rotatably mounted on the quick-release buckle housing 41 via the quick-release buckle shaft 44. The quick-release buckle housing 41 has mounting grooves 410 on both sides to accommodate the quick-release buckle steel hooks 42, and the two quick-release buckle steel hooks 42 are fixedly embedded in the mounting grooves 410 of the quick-release buckle housing 41 via the quick-release buckle shaft 44.

[0052] The storage mechanism is detachably connected to the column 1 via quick-release connecting device 4 as follows:

[0053] The connecting parts 95 of the storage mechanism (e.g., the connecting part of the clothes rod 91 is the clothes rod arm 95) have clearance spaces 950 for the quick-release buckle steel hooks 42 to pass through (this could also be a space or a through hole for the steel hooks 42 to pass through; for example, when the connecting part of the clothes rod 91 is the clothes rod arm 95, it is a clearance space; if it is a connecting part of a double or single movable drawer, this clearance space 950 could be a through hole); the connecting parts of the storage mechanism in this embodiment 95 (for example, the connecting part of the clothes rod 91 is the clothes rod support arm 95) respectively have lock holes 951 that cooperate with the quick-release buckle eccentric lock 43 (the overall locking principle of the quick-release buckle eccentric lock is to use the eccentric mechanism to compress the elastic material and lock the storage mechanism through greater friction. In the preferred embodiment, the cooperation between the locking part and the lock hole is added, which is a secondary safety protection setting to prevent the storage mechanism from falling due to the failure of the elastic compression or human error).

[0054] When locking is required, the corresponding quick-release buckle steel hooks 42 pass through the clearance space 950 on the connecting part of the corresponding storage mechanism and hang on the mounting hole 104 of the steel adjusting strip 102 of the column 1. The corresponding quick-release buckle eccentric lock 43 is flipped so that the quick-release buckle eccentric lock 43 presses the connecting part of the corresponding storage mechanism, thus fixing the corresponding storage mechanism to the column 1.

[0055] When unlocking is required, flip the corresponding quick-release buckle eccentric lock 43 to disengage it from the connecting part of the corresponding storage mechanism, and remove the corresponding quick-release buckle steel hook 42 from the mounting hole 104 of the steel adjusting strip 102 of the column 1 to complete the unlocking.

[0056] The connecting component 95 of the storage mechanism has a multi-layer structure, wherein the layer closest to the column is an elastic material layer 952, and the other layers are rigid material layers 953.

[0057] The quick-release eccentric lock 43 is generally in the shape of a flat shell, with a locking part 431 at the top. This locking part is shaped like an eccentric shaft, and a protruding locking part 432 is provided on the eccentric shaft 431. By rotating the quick-release eccentric lock 43, the locking part 432 can engage or disengage with the lock hole 951 on the component to be connected. (The overall locking principle of the quick-release eccentric lock is to use the eccentric mechanism to compress the elastic material, thereby locking the storage mechanism through greater friction. The addition of the locking part and the lock hole in this solution is a secondary safety protection feature, which prevents the storage mechanism from falling due to failure of the elastic compression or human error.)

[0058] In this embodiment, as Figure 26As shown, the frame-type wardrobe is equipped with a lighting system. The wiring conduit of the lighting system of the frame-type wardrobe consists of the following components: the wall track 3 is in the shape of an "L" (the wall track 3 and the transformer 302 are fixed on the wall 303), the wire clip 20 is clipped on the top plate 2 and the L-shaped wall track 3, and the wiring of the entire lighting system 301 runs from the "L"-shaped wall track 3 to the corresponding suspended top plate support device 5 after being limited by the wire clip 20 (the corresponding suspended top plate support device 5 can be a hollow structure for wiring), and then from the suspended top plate support device 5 to the corresponding hollow column 1, and then from the column 1 to the LED light strip 105 on the column 1.
