Description

Technical Field

[0001] This utility model relates to a network communication cabinet, and more particularly to a foldable frame structure for a 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 the individual boards and then packing them together to reduce the transport volume. However, when users use them, they need to assemble the individual boards, 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 frame structure for a network cabinet, including a front frame with a front door, two side frames, side panels, a top cover, a bottom plate, and a back plate; characterized in that: the side frame includes a first side frame and a second side frame, the front edge of the first side frame is hinged to the side of the front frame, so that the first side frame can be flipped inward relative to the front frame, and the front edge of the second side frame is hinged to the rear edge of the first side frame, so that the second side frame can be flipped outward relative to the first side frame; the first side frame and the second side frame can swing to an unfolded state perpendicular to the front frame, and the first side frame and the second side frame can also be folded in half and then swinged to a folded state that is laterally close to the front frame; the top cover and the bottom plate are detachably installed above and below the two side frames in the unfolded state, the back plate is detachably installed at the rear of the two side frames in the unfolded state, and the side panels are installed on the sides of the side frames.

[0008] To better secure the first side frame relative to the front frame in the unfolded state, as an improvement, the first side frame in the unfolded state is positioned against the front frame by a first locating pin. The locating pin can be a screw or a bolt and nut structure.

[0009] To better secure the first side frame relative to the second side frame in the unfolded state, as an improvement, the second side frame and the first side frame are fixed together in the unfolded state by hand-press screws.

[0010] Specifically, the aforementioned hand-operated screw is fixed to the front wall of the second side frame, and the rear wall of the first side frame has a notch through which the rod of the hand-operated screw passes. During adjustment, the first and second side frames are in the unfolded state, the rod of the hand-operated screw passes through the notch on the rear wall of the first side frame, and then the handle of the hand-operated screw is pressed. Under the biasing action, the two nuts on the upper and lower parts of the hand-operated screw move closer to each other, pressing the front wall of the second side frame and the rear wall of the first side frame together.

[0011] Preferably, the front edge of the second side frame is hinged to the rear edge of the first side frame via a hinge. The two halves of the hinge have large fixing surfaces with the first and second side frames, making the first and second side frames more stably hinged together.

[0012] To facilitate disassembly and assembly, as a preferred embodiment of the hinged connection between the first side frame and the front frame, the upper and lower ends of the front edge of the first side frame are connected to the front frame via a rotating structure. The rotating structure includes a mounting base fixed on the first side frame, a pin constrained on the mounting base and capable of sliding up and down, a shaft hole for the pin to be inserted into on the front frame, and a spring acting on the mounting base to keep the pin inclined to be inserted into the shaft hole.

[0013] During installation, simply pull the pin inward to place the front edge of the first side frame on the front frame, aligning the pin with the corresponding socket. Release the pin, and the spring will allow it to insert into the socket, completing the hinge connection. For disassembly, pull the pin inward again to disengage it from the socket, allowing the connecting plate to be removed from the front frame, or the side frame to be removed from the connecting plate.

[0014] To achieve screwless installation of the back panel, the back panel has inwardly extending positioning plates on both the left and right sides. These positioning plates have positioning holes and are fitted against the inner wall of the second side frame, then positioned with the second side frame by second positioning pins. The positioning pins can be screws or bolt-nut structures.

[0015] 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, covering the outer side of the upper beams of the first and second side frames. An L-shaped upper positioning plate is fixed to the inner top surface of the top cover. The top surfaces of the first and second side frames have upper positioning holes that engage with the upper positioning plate, which is then inserted into the upper positioning holes. Similarly, the bottom plate has upward-extending lower mounting walls on both sides, covering the outer side of the lower beams of the first and second side frames. An L-shaped lower positioning plate is fixed to the inner bottom surface of the bottom plate. The bottom surfaces of the first and second side frames have lower positioning holes that engage with the lower positioning plate, which is then inserted into the lower positioning holes. During top cover assembly, simply insert the upper positioning plate into the upper positioning hole and then push the top cover forward to complete the snap-fit ​​installation. The bottom plate installation is the same.

[0016] To facilitate the removal and installation of the side panels for maintenance from the side, as an improvement, the aforementioned side panels are installed between the upper and lower mounting walls using side panel locks.

[0017] To facilitate the installation of communication equipment into the cabinet, the inner sides of both the first and second side frames are fixed with longitudinally arranged mounting brackets for installing communication equipment; to facilitate wall mounting of the network cabinet, the rear wall of the second side frame is provided with wall mounting holes.

[0018] 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, and the side frame is hinged to the front frame as a whole. The side frame is designed as two parts, a first side frame and a second side frame, which can be hinged to each other. The first side frame folds inward relative to the front frame, and the second side frame folds outward relative to the first side frame. After the first and second side frames are folded, they swing with the first side frame to a folded state that is laterally close to the front frame, thereby reducing the volume of the network cabinet during packaging and transportation, and reducing packaging and transportation costs. During assembly, it is only necessary to swing the first and second side frames to an unfolded state perpendicular to the front frame, and then install the side panels, top cover, bottom panel, and back panel into the corresponding positions. Assembly is also quite convenient, saving the operation of independently installing the two side frames and the front door. Attached Figure Description
