Description

Technical Field

[0001] The utility model relates to a cabinet, in particular to a cabinet foot with hidden casters. Background Art

[0002] A cabinet is an independent or self-supporting casing used to house electrical or electronic equipment. Cabinets are generally equipped with doors, removable or non-removable side panels and back panels. Cabinets are an indispensable component of electrical equipment and are the carrier of electrical control equipment. They are generally made of cold-rolled steel plates or alloys. They can provide waterproof, dustproof, and anti-electromagnetic interference protection for stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.

[0003] The Chinese patent with patent number CN201711275928.0 discloses "A cabinet foot with hidden casters". By adjusting the bolts, the casters are pushed and retracted with the intersection axis as the center of the circle, so that the casters can be hidden inside the cabinet after use, which is convenient for the transportation and daily placement of the cabinet.

[0004] This structure has certain advantages, but still has some shortcomings:

[0005] When the cabinet needs to be moved again after the casters are hidden inside, the casters are driven to rotate and extend out of the bottom of the cabinet by moving the adjusting bolts outward. During this operation, the load-bearing capacity of the casters adjusted in sequence is too large, which may easily cause the cabinet to be unstable. In addition, the casters are difficult to extend out of the bottom of the cabinet due to the large force, making the operation difficult. When the casters are retracted, one side of the cabinet touches the ground first, which may easily cause the cabinet to tilt, making it inconvenient to place and move the cabinet safely.

[0036] like Figure 2-3 As shown, a cabinet foot with hidden casters includes an adjusting device 3, which includes an assembly 31, a universal brake wheel 32, a strong spring 33, a movable rod 34, a movable plate 35, a folding piece 36, a block 37, and an auxiliary support piece 38; the assembly 31 is installed at the bottom end of the cabinet, and the universal brake wheel 32 is installed inside it with bolts, the left end of the strong spring 33 is fixed to the assembly 31, the left end of the movable rod 34 is elastically connected to the assembly 31 with the strong spring 33, the left end of the movable plate 35 is fixed to the movable rod 34, and it is movable inside the assembly 31, the top of the folding piece 36 is fixed to the movable plate 35, the right end of the auxiliary support piece 38 is fixed to the assembly 31, and the left end is fixed to the cabinet foot body 1.

[0037] In this embodiment, a block 37 is fixed to the bottom end of the movable plate 35, and the right end of the block 37 is in contact with the folding piece 36. The setting of the block 37 prevents the folding plate 36 from hitting the assembly 31 when the movable plate 35 retracts, thereby protecting the folding plate 36. The cross-section of the movable plate 35 is "L"-shaped, which is convenient for pushing the movable plate 35 outward from the inside and pulling the strong spring 33. Two groups of folding pieces 36 are provided, which are symmetrically distributed at the front and rear ends of the movable plate 35, so as to hide the universal brake wheel 32 inside and realize the purpose of hidden casters of the cabinet feet. The folding plate 36 is made of plastic, is soft and thin, and can be folded to play a shielding role. At the same time, it is also convenient for the folding plate 36 to be folded upward when the universal brake wheel 32 is pressed by hand to provide a movable space for operation.

[0038] like Figure 5-6 As shown, a cabinet foot with hidden casters, the auxiliary support member 38 includes a base plate 381, a guide rod 382, ​​a limit rod 383, a support seat 384, and a support foot 385. The left and right ends of the base plate 381 are respectively fixed to the cabinet foot body 1 and the assembly body 31, and its top end is fixed to the cabinet, the bottom end of the base plate 381 is fixed with a guide rod 382, ​​the top end of the limit rod 383 is threadedly connected to the base plate 381, and the bottom end is rotatably connected to the support seat 384, the interior of the support seat 384 is slidably connected to the guide rod 382, ​​and the support foot 385 is fixed to the bottom end of the support seat 384.

[0039] In this embodiment, multiple groups of support legs 385 are provided to play a stable supporting role, which reduces the pressure of the overall gravity on the universal wheel 2 and the universal brake wheel 32 when the cabinet is placed.
