Description

Cabinet

The invention relates to a cabinet, in particular to a server cabinet.

In the prior art, electronic devices such as servers and the like are often placed in a stacked manner in a cubic cabinet. However, the height of a typical cabinet is usually high. When a user with a short body needs to place the server in the height of the cabinet, or when the server located at a high position in the cabinet is maintained, it can be obtained by using other climbing tools. The operation is very inconvenient.

In view of the above, it is necessary to provide a cabinet that can facilitate the user to carry out the climbing operation.

A cabinet includes a frame and a folding ladder. The folding ladder is provided with a receiving portion mounted in the frame and at least one folded portion received in the receiving portion. The folded portion is slidably coupled to the receiving portion. When the folded portion is pulled outward, the folded portion can be opened in a stepped manner.

The cabinet is designed to facilitate the user to climb up by installing an extendable folding ladder in the rack, and has a simple structure and convenient use.

Referring to FIG. 1 and FIG. 3 , a preferred embodiment of the cabinet of the present invention includes a rack 10 that houses a plurality of electronic devices 30 and a folding ladder 20 that is mounted on the rack 10 .

Referring to FIG. 1 and FIG. 2 together, the folding ladder 20 includes a receiving portion 22 and two folding portions 25 mounted on the receiving portion 22.

The receiving portion 22 includes a bottom plate 21 and an upper cover 23 that can be attached to the bottom plate. The upper cover 23 includes two opposite side walls 231, and the front and rear ends of each side wall 231 are respectively bent outward to form a fixing portion 233. A sliding rail 235 having an "L" shape in cross section is disposed on the inner side of each of the side walls 231. A vertical groove 237 is formed on the vertical surface of each of the sliding rails 235 along the same horizontal line.

Each of the folding portions 25 includes a first layer 251, a second layer 252, a first supporting portion 254 pivotally connected between the first layer 251 and the second layer 252, and a pivoting The second support portion 253 is connected to the second layer plate 252. The rear side of the first layer plate 251 is provided with a sliding bar 255 protruding from both ends. The first supporting portion 254 includes a pivoting shaft 2541 and two parallel fixing rods 2543 extending perpendicularly from the two ends of the pivoting shaft 2541. The pivoting shaft 2541 and the two fixing rods 2543 form a receiving cavity. Both ends of the pivot shaft 2541 are rotatably connected to both ends of the front side of the first layer plate 251, respectively. The rear side of the second layer 252 and the second support portion 253 are respectively provided with a pivot rod 2524, 2534, and the second layer plate 252 is rotatably connected to the first support portion via a pivot rod 2524 thereon The free ends of the two fixing rods 2543 of 254, the second supporting portion 253 is rotatably coupled to the front side of the second layer plate 252 through a pivoting rod 2534 thereon. The first layer plate 251, the second layer plate 252 and the second support portion 253 each include two end walls, and the inner side of each end wall of the first layer plate 251 and the corresponding fixing rod 2543 of the first support portion 254 The outer side is connected through a bendable first support rod 257; the outer side of each end wall of the second layer 252 and the inner side of the corresponding fixed rod 2543 of the first support portion 254 are transmitted through a bendable second support rod The inner side of each end wall of the second layer 252 is connected to the outer side of the corresponding end wall of the second support portion 253 through a bendable third support rod 258. Each of the first support rod 257, the second support rod 256 and the third support rod 258 are It consists of two mutually articulated rods. When the two rods of each first support rod 257 are rotated to 180°, the plane of the first support portion 254 is perpendicular to the first layer plate 251; when the two rods of each second support rod 256 are turned The plane of the first supporting portion 254 is perpendicular to the second layer 252 when it is 180°; when the two rods of each third supporting rod 258 are rotated to 180°, the second supporting portion 253 is The second ply 252 is vertical. The free ends of the second supporting portion 253 protrude from the two spaced supporting legs 2532.

At the time of assembly, the two folded portions 25 are slidably received on the front and rear sides of the accommodating portion 22, respectively. For each of the folded portions 25, the second support portion 253 is rotated to be folded over the second laminate 252. The second layer plate 252 is rotated to be received in the receiving cavity of the first supporting portion 254 together with the second supporting portion 253. Then, the first supporting portion 254 is rotated to be folded together with the second layer 252 and the second supporting portion 253 at the bottom of the first layer plate 251, as shown in FIG. Each folded portion 25 of the folded portion is fitted into the upper cover 23 of the receiving portion 22 such that the slide bars 255 of the first layer plate 251 of the two folded portions 25 are adjacent to each other and located in the middle of the upper cover 23, and each fold Both ends of the sliding bar 255 of the portion 25 are slidably received in the corresponding sliding grooves 237 of the two sliding rails 235 in the upper cover 23, respectively. The bottom plate 21 of the accommodating portion 22 is fixed to the bottom of the upper cover 23, and the folding ladder 20 is assembled. Finally, the folding ladder 20 is mounted on the frame 10 through a plurality of locking members, such as screws, respectively, passing through the four fixing portions 233 of the receiving portion 22 and locking into the middle of the four pillars of the frame 10. Inside, as shown in Figure 3.

Referring to FIG. 1 , in use, the folded portion 25 of the user facing side is extracted from the receiving portion 22 of the folding ladder 20 installed in the frame 10 until the ends of the sliding bar 255 of the folded portion 25 . The ends of the corresponding chutes 237 in the receiving portion 22 are respectively abutted. The first support portion 254 is rotated downward to straighten the two first support bars 257, and the first support portion 254 is perpendicular to the first layer plate 251. The second layer 252 is further rotated outward and downward until the two second support bars 256 are straightened, and the second layer plate 252 is perpendicular to the first support portion 254. Rotating the second support portion 253 downward to the two third support bars 258 are straightened, the second support portion 253 is perpendicular to the second layer plate 252, and the second support portion The two support legs 2532 of 253 are supported on the ground. At this time, the folded portion 25 of the folding ladder 20 protrudes in a stepped manner from the cabinet, the first layer plate 251 and the second layer plate 252 are parallel to the ground, and the second layer plate 252 is supported by the second supporting portion 253 and The third support rod 258 is supported by the second layer plate 252 and the second support rod 256. The first layer plate 251 is supported by the first support portion 254 and the first support rod 257. The user can easily operate the electronic device at the height of the cabinet by stepping on the first layer 251 or the second layer 252 of the folding ladder 20 without further searching for the climbing tool.

When the folding ladder 20 is not required to be used, the folding portion 25 of the folding ladder 20 can be folded and then stored in the accommodating portion 22 of the rack 10, thereby facilitating the user to lower the electronic equipment of the cabinet. Take action.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
