Description

Technical Field

[0001] This utility model relates to a network communication cabinet, and more particularly to a foldable network cabinet. Background Technology

[0002] Communication cabinets are generally used in computer network equipment management centers. They are mainly used to install hubs, routers, network switches, servers or other data transmission equipment in a unified space to realize the connection and management between devices, and at the same time facilitate the centralized management of the normal operation and maintenance of the above-mentioned devices.

[0003] Therefore, the applicant has applied for Chinese utility model patent No. ZL202020426112.4 (authorization announcement No. CN212163882U), which discloses a convenient detachable communication cabinet. During assembly, the front and rear door frames are first fixed to the bottom of the chassis with screws. Then, three crossbeams are fixed between the two uprights of the front and rear door frames, respectively. Next, the bracket is fixed to the crossbeams. Then, the side panels are installed. The positioning holes at the bottom of the side panels are aligned with the positioning pins on the side mounting wall and inserted. Simultaneously, the latch is forced inward with a finger. After the side panels are in place, the finger is released, and the latch springs into place, completing the side panel installation. Next, the top cover is installed and fixed to the top of the front and rear door frames with screws. Finally, the front and rear doors are installed. The chassis, front door frame, rear door frame, front door, rear door, top cover, and two side panels constituting this cabinet can be shipped separately in bulk. When installing it on the front and rear door frames, multiple people are required to operate it. One person holds the door frame while another person aligns it with the corresponding mounting hole and then screws in the screws, which is inconvenient.

[0004] Existing server racks can only be transported by disassembling each panel, column, and beam separately and then packing them together to reduce the transport volume. However, when users use them, they need to assemble each panel, column, and beam in the same way, which is laborious and time-consuming.

[0005] Therefore, how to design a network cabinet that is both easy to transport and quick to assemble is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a foldable frame structure for network cabinets that is convenient to transport and can be quickly assembled, in view of the above-mentioned existing technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a foldable network cabinet, including a door, a top cover, a bottom plate, side plates, a back plate, and side frames located on the left and right sides, wherein the side plates are detachably installed on the side frames; characterized in that: the front parts of the two side frames are connected by two sets of front connecting rod assemblies arranged vertically and horizontally, and the rear parts of the two side frames are connected by two sets of rear connecting rod assemblies arranged vertically and horizontally, both the front connecting rod assemblies and the rear connecting rod assemblies can be folded down, and the front connecting rod assemblies and the rear connecting rod assemblies are vertically staggered; in the folded state, the two side frames are close to each other, and the front connecting rod assemblies and the rear connecting rod assemblies are folded between the two side frames; in the unfolded state, the two side frames are far apart from each other, and the front connecting rod assemblies and the rear connecting rod assemblies are extended and supported between the two side frames; the top cover and the bottom plate are detachably installed above and below the two side frames, respectively, the door is hinged to the front part of one of the side frames, and the back plate is detachably installed on the back side between the two side frames.

[0008] Preferably, the aforementioned front linkage assembly includes two front long linkages and one front intermediate linkage. The outer ends of the two front long linkages are hinged to the side frames on corresponding sides, and the inner ends of the two front long linkages are respectively hinged to the two ends of the front intermediate linkage. The rear linkage assembly includes two rear long linkages and one rear intermediate linkage. The outer ends of the two rear long linkages are hinged to the side frames on corresponding sides, and the inner ends of the two rear long linkages are respectively hinged to the two ends of the rear intermediate linkage. The intermediate linkage is shorter, and the thickness of the folded long linkages is basically the same as that of the intermediate linkage, allowing the folded long linkages to contact each other, resulting in a better folding effect.

[0009] To provide a secure mounting position for the top cover and bottom plate, the inner side of the aforementioned side frame is provided with an upper and lower protrusion extending in the front-to-back direction. The top cover is snapped onto and rests on the upper protrusion, and the bottom plate is snapped onto and rests on the lower protrusion. This allows for an embedded installation of the top cover and bottom plate.

[0010] To achieve screwless installation of the top cover and bottom plate, as an improvement, the top cover has downward-extending upper mounting walls on both sides. Each upper mounting wall has an L-shaped upper positioning plate. Two upper positioning holes are formed on the upper protrusions of the top mounting walls, engaging with the upper positioning plates. The upper positioning plates are inserted into the upper positioning holes, and the upper mounting walls rest on the upper protrusions. Similarly, the bottom plate has upward-extending lower mounting walls on both sides. Each lower mounting wall has an L-shaped lower positioning plate. Two lower positioning holes are formed on the lower protrusions of the bottom mounting walls, engaging with the lower positioning plates. The lower mounting walls rest on the lower protrusions. During top cover assembly, simply place the top cover on the upper protrusions so that the upper positioning plates are inserted into the upper positioning holes, and then push the top cover forward to complete the snap-fit ​​installation. The bottom plate installation is the same.

[0011] To facilitate the installation of communication equipment into the cabinet, two longitudinally arranged mounting brackets for installing communication equipment are fixed on the inner side of the aforementioned side frame. The two mounting brackets are fixed on the upper and lower protrusions and are spaced apart from each other.

[0012] To achieve screwless installation of the back panel, the upper edge of the back panel has an inwardly and downwardly bent limiting part, and the lower edge of the back panel has inwardly extending positioning plates on both sides. The positioning plates have positioning holes. The positioning plates are attached to the inner wall of the side frame and positioned with the side frame by positioning pins. The limiting part is fastened to the rear linkage assembly located at the top.

[0013] To facilitate the removal and installation of the side panels for maintenance from the side, as an improvement, the aforementioned side panels are mounted on the side frame using side panel locks.

[0014] To facilitate wall mounting of the network cabinet, the rear wall of the aforementioned side frame is provided with wall mounting holes.

[0015] One of the side frames has a hinge seat on its front wall.

[0016] Compared with the prior art, the advantages of this utility model are as follows: During transportation, the top cover, side panels, bottom panel, and back panel are removed. Since the side frames on both sides are connected by foldable front and rear linkage assemblies, after the front and rear linkage assemblies are folded, the two side frames are close to each other, and the front and rear linkage assemblies are folded between the two side frames. Then, the top cover, side panels, bottom panel, and back panel are stacked on the side frames, thereby reducing the volume of the network cabinet during packaging and transportation, and reducing packaging and transportation costs. During assembly, the side frames on both sides are pulled apart to move away from each other, the front and rear linkage assemblies are straightened and supported between the two side frames, and then the top cover, back panel, bottom panel, and side panels are installed in the corresponding positions. Assembly is also quite convenient. Attached Figure Description
