Description

Technical Field

[0001] This utility model relates to the field of computer network cabinets, and in particular to a folding mechanism for a network cabinet. Background Technology

[0002] A computer network cabinet (also known as a network rack or server rack) is an enclosed structure used to store and manage computer equipment, network equipment, and related components. It provides a secure, efficient, and clean environment for easy installation, maintenance, and management of the equipment. In small offices with limited space, wall-mounted computer network cabinets can be used, effectively saving floor space by installing them on the wall.

[0003] Currently, existing network cabinets are often monolithic structures, requiring assembly via screws or welding, resulting in low assembly efficiency. Therefore, existing network cabinets have been further optimized, as shown in Chinese Utility Model Patent No. CN202222968324.7 (Authorization Announcement No. CN218888827U). This network cabinet includes a first plate, a second plate, and a third plate. Two first plates are arranged opposite each other, and two second plates are arranged opposite each other and rotatably connected between the two first plates. Each second plate includes multiple rotatably connected sub-plates. The third plate is detachably connected to the same end of the first and second plates, thus giving the network cabinet a foldable function.

[0004] While the aforementioned network cabinets feature a folding function, the folding mechanisms used in these cabinets typically fold the front and rear panels. These mechanisms are often side panels formed by the rotating connection of multiple sub-panels, resulting in a more complex structure that is difficult to manufacture. Furthermore, network cabinets assembled using this folding mechanism tend to have poor structural strength, negatively impacting the user experience. Therefore, further improvements to the folding mechanisms of network cabinets are necessary. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a folding mechanism with a reasonable structure and higher assembly efficiency in view of the above-mentioned existing technology. This folding mechanism is applied to network cabinets.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the folding mechanism of the network cabinet includes a front frame and a side frame assembled from multiple columns and beams. The front frame and the side frame are connected by a folding mechanism. The folding mechanism includes mounting plates at the four corners of the front frame and first connecting blocks at the upper and lower ends of the side frame. The mounting plates are provided with rearward-extending grooves. The cross-section of the first connecting blocks is T-shaped and corresponding to the grooves. The first connecting blocks are disposed in the grooves and can slide along the grooves. The side frame slides along the grooves to a position close to the front frame with the help of the first connecting blocks. The front frame and the side frame are perpendicular to each other and relatively fixed to allow the folding mechanism to unfold. The side frame slides along the grooves to a position away from the front frame with the help of the first connecting blocks. The side frame can rotate relative to the front frame to allow the folding mechanism to fold.

[0007] Furthermore, the folding mechanism also includes a locking part. When the folding mechanism is in the unfolded state, the locking part ensures that the vertically arranged front frame and side frame are relatively fixed. This relative fixation of the front and side frames makes the structure of the network cabinet more stable in the unfolded state.

[0008] Furthermore, the locking part includes a second connecting block disposed on the front frame and a gourd-shaped hole disposed on the side frame. The second connecting block has a T-shaped cross-section and can slide relative to the front frame. The head size of the second connecting block is larger than the small end of the gourd-shaped hole but smaller than the large end of the gourd-shaped hole. When the second connecting block is inserted into the gourd-shaped hole and located at the small end of the gourd-shaped hole, the locking part is in a locked state. The locking part can be locked or unlocked without the use of screws. The locked state of the locking part can fix the front frame and the side frame together. The unlocked state of the locking part is when the second connecting block is not inserted into the gourd-shaped hole or is located at the large end of the gourd-shaped hole.

[0009] To ensure a more accurate vertical connection between the side frame and the front frame, preferably, the front frame is provided with positioning posts, and the side frame is provided with positioning holes corresponding to the positioning posts. Inserting the positioning posts into the corresponding positioning holes allows for a more accurate vertical alignment of the front frame and the side frame, enabling the locking mechanism to secure the relative positions of the front frame and the side frame.

[0010] Furthermore, the space formed between two adjacent mounting plates allows for the installation of the side frame. The mounting plates can be fixed to the front frame with screws or directly welded to the front frame, thus simplifying the structure of the folding mechanism.

[0011] Furthermore, the slide grooves on the left and right sides of the front frame are of different lengths. When the folding mechanism is in the folded state, one side frame rests on the front frame, and the other side frame rests on its opposite side frame. The different lengths of the slide grooves allow the two side frames to be stacked when folded.

[0012] Compared with existing technologies, the advantages of this invention are as follows: The folding mechanism allows the two side frames of the network cabinet to be folded parallel to the front frame, thus simplifying the assembly process by requiring only the assembly of the panel body. Furthermore, the folding mechanism is located on both the side and front frames, resulting in a simpler structure and easier manufacturing. Additionally, this folding mechanism eliminates the need for screws during assembly or disassembly, further simplifying the process and resulting in a stronger assembled network cabinet.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-5 The figure shown is the preferred embodiment of this utility model.

[0020] like Figure 1 and Figure 2As shown, the folding mechanism in this embodiment is applied to a network cabinet. The network cabinet includes a front frame 3 and side frames 4 assembled from multiple uprights 1 and crossbeams 2, as well as a top plate, a rear plate, and a bottom plate. The top plate, rear plate, and bottom plate are detachably mounted on the front frame 3 and side frames 4. The front frame 3 and side frames 4 are cuboid structures with a hollow center. The front frame 3 and side frames 4 are connected by a folding mechanism. The front frame 3 has four mounting plates 33, which are fixed at the four corners of the front frame 3. The space formed between two adjacent mounting plates 33 allows the side frames 4 to be installed.

[0021] like Figures 3-5 As shown, the folding mechanism of this embodiment includes mounting plates 33 disposed at the four corners of the front frame 3 and first connecting blocks 41 disposed at the upper and lower ends of the side frame 4. The mounting plates 33 are provided with rearward extending grooves 31. The lengths of the grooves 31 on the left and right sides of the front frame 3 are inconsistent. The cross-section of the first connecting block 41 is T-shaped and is disposed corresponding to the grooves 31. The first connecting block 41 is disposed in the grooves 31 and can slide along the grooves 31. The side frame 4 slides along the grooves 31 to a position close to the front frame 3 with the help of the first connecting block 41. The front frame 3 and the side frame 4 are perpendicular and relatively fixed to allow the folding mechanism to unfold. The side frame 4 slides along the grooves 31 to a position away from the front frame 3 with the help of the first connecting block 41. The side frame 4 can rotate relative to the front frame 3 to fold the folding mechanism. When the folding mechanism is in the folded state, one side frame 4 rests on the front frame 3, and the other side frame 4 rests on its opposite side frame 4. Furthermore, the folding mechanism of this embodiment also includes a locking part. When the folding mechanism is in the unfolded state, the locking part can fix the vertically arranged front frame 3 and side frame 4 relatively. The locking part includes a second connecting block 34 provided on the front frame 3 and a gourd hole 43 provided on the side frame 4. The cross-section of the second connecting block 34 is T-shaped. The second connecting block 34 can slide relative to the front frame 3. The head size of the second connecting block 34 is larger than the small end of the gourd hole 43 and smaller than the large end of the gourd hole 43. When the second connecting block 34 is inserted into the gourd hole 43 and located at the small end of the gourd hole 43, the locking part is in the locked state. The locking part is unlocked when the second connecting block 34 is not inserted into the gourd hole 43 or is located at the large end of the gourd hole 43. In addition, the front frame 3 of this embodiment is provided with a positioning post 32, and the side frame 4 is provided with a positioning hole 42 corresponding to the positioning post 32. The positioning post 32 is inserted into the corresponding positioning hole 42, which can make the position of the front frame 3 and the side frame 4 perpendicularly set more accurate, and the locking part can lock the relative position of the front frame 3 and the side frame 4.

[0022] The process flow of this embodiment is as follows: First, rotate the side frame 4, which is in a folded state, relative to the front frame 3, so that the side frame 4 is opened relative to the front frame 3, that is, the side frame 4 is set perpendicular to the front frame 3. Then, slide the first connecting block 41 of the side frame 4 along the slide groove 31 to a position close to the front frame 3, so that the positioning post 32 of the front frame 3 is inserted into the positioning hole 42 of the side frame 4. The second connecting block 34 is inserted into the gourd hole 43 and is located at the large end of the gourd hole 43. Then, the user pushes the second connecting block 34 to slide the second connecting block 34 to the small end of the gourd hole 43, thereby completing the fixed connection between the front frame 3 and the side frame 4.
