Detailed Implementation

[0028] The present invention will be further described in detail below with reference to specific embodiments. Figures 1-6 The diagram shows the structure of the network cabinet disclosed in this utility model. It is evident that it mainly consists of a vertical cabinet 1, network switches 2, an auxiliary management unit 3, and a mobile unit 4. The vertical cabinet 1 serves as the core carrier for equipment installation and protection, providing stable installation space for the network switches 2 and the auxiliary management unit 3. Multiple network switches 2, key components for network signal exchange and transmission, are built into the vertical cabinet 1 and arranged in a linear array along the height direction. The auxiliary management unit 3 uses the vertical cabinet 1 as its installation base and, in conjunction with the network switches 2, performs functions such as power supply, cable management, and environmental control. The mobile unit 4 is located at the bottom of the vertical cabinet 1 to ensure excellent mobility and flexibility of the cabinet.

[0029] As Figures 1-4As shown, the vertical cabinet 1 is a modular structure, mainly composed of the cabinet body 11, front door assembly 12, rear door assembly 13, left door assembly 14, and right door assembly 15. The front door assembly 12, rear door assembly 13, left door assembly 14, and right door assembly 15 are all movably connected to the cabinet body 11, forming an openable door design. This eliminates physical obstacles to equipment maintenance. Regardless of which location of the network switch 2 within the cabinet 11 needs to be operated, seamless access can be achieved by opening and closing the corresponding door. Especially in server room scenarios with densely packed cabinets, there is no need to rely on a single direction of operating space. Maintenance personnel can flexibly choose to open and close the cabinet doors according to the site layout without adjusting their operating posture or moving surrounding cabinets, significantly reducing the difficulty of maintenance.

[0030] The openable door designs of the front cabinet door assembly 12, rear cabinet door assembly 13, left cabinet door assembly 14, and right cabinet door assembly 15 are similar. The following detailed explanation uses the front cabinet door assembly 12 as an example. Figure 2 As shown, the front cabinet door assembly 12 includes a cabinet door 121, a hinge 122, and a door lock 123. One end of the hinge 122 is connected to the cabinet body 11, and the other end is connected to the cabinet door 121 to enable the cabinet door 121 to rotate and open. The hinge 122 is a detachable structure, and is fastened to both the cabinet body 11 and the cabinet door 121 by means of a first bolt assembly (not shown in the figure). Its rotation range is not less than 120°, providing sufficient space for operation and maintenance. The detachable structure facilitates the maintenance and replacement of the hinge 122. The door lock 123 is located on the side of the cabinet door 121 away from the hinge 122, and is used to lock the cabinet door 121 after it is closed, ensuring the safety of the equipment inside the cabinet body 11.

[0031] In addition, the front cabinet door assembly 12 also integrates a buffer strip. The buffer strip is distributed in a closed ring along the edge of the cabinet door 121, which is used to form an elastic contact with the cabinet body 11 when the cabinet door 121 is closed. In this way, the impact force when the cabinet door 121 and the cabinet body 11 are closed is effectively reduced to reduce noise, and the sealing between the cabinet door 121 and the cabinet body 11 is enhanced to reduce the intrusion of dust and moisture.

[0032] like Figure 5 , Figure 6As shown, mounting columns 16 extending along the height direction are provided on both sides of the interior of the cabinet 11. The mounting columns 16 are C-shaped cold-rolled steel columns, possessing high structural strength and providing stable mounting support for the network switches 2. Mounting holes distributed along the height direction are provided on the inner sidewalls of the mounting columns 16, with a spacing of 25mm along the height direction. This is compatible with the height of 1U and 2U network switches 2, meeting the installation requirements of different sizes of network switches 2. Furthermore, a 10-15mm gap is reserved between adjacent network switches 2, which facilitates heat dissipation during operation, preventing heat accumulation due to dense equipment arrangement and ensuring equipment operational stability.

[0033] Network switch 2 is fixedly connected to mounting post 16 via mounting connector 17, such as Figures 7-9 As shown, the mounting connector 17 includes a second bolt assembly (not shown) that adapts to the mounting hole group and a slidably adjustable slide rail assembly 171. The slide rail assembly 171 includes a fixed rail 1711 and a movable rail 1712. The fixed rail 1711 is fastened to the mounting column 16 by the second bolt assembly. The movable rail 1712 is detachably connected to the fixing ears on both sides of the network switch 2. A ball-bearing slider structure 1713 is provided between the movable rail 1712 and the fixed rail 1711 to realize the pull-out opening and closing of the network switch 2. The pull-out stroke is not less than 2 / 3 of the length of the network switch 2. The pull-out design allows the installation, disassembly, and maintenance of the network switch 2 to be carried out without going deep into the cabinet 11, greatly improving the convenience of operation. The ball-bearing slider structure 1713 ensures the smoothness of the pull-out process.

[0034] Depend on Figure 7 As can also be clearly seen in the diagram, the slide rail assembly 171 is further equipped with a limit locking structure 1714. The limit locking structure 1714 (consisting of at least two sets of locking screws) is located at the end of the fixed rail 1711. When the movable rail 1712 is pulled out to its maximum stroke, the network switch 2 and the fixed rail 1711 are fixed together by multiple sets of locking screws, preventing the network switch 2 from being damaged due to accidental slippage during the pulling and maintenance process, and further improving operational safety.

[0035] like Figure 10As shown, the walking unit 4 is located at the bottom of the cabinet 11, and includes four sets of casters 41. The four sets of casters 41 correspond to the four corners of the bottom of the cabinet 11 and are fastened to the cabinet 11 by the third bolt assembly 42. This effectively ensures the stability of the cabinet during movement and facilitates the adjustment of the cabinet's position in the computer room. The casters 41 are made of polyurethane, which has good wear resistance and shock absorption. Their diameter is preferably 50-70mm to better adapt to the computer room floor environment. Furthermore, shock-absorbing pads are placed between the casters 41 and the cabinet 11, which can effectively buffer the vibration generated during the movement and operation of the cabinet and reduce the impact of vibration on the internal precision equipment.

[0036] Finally, it should be noted that the bottom of the cabinet 11 is also equipped with a leveling unit 5, which includes multiple sets of leveling bolt assemblies 51. When the network cabinet is moved to the designated position, the multiple sets of leveling bolt assemblies 51 are adjusted to keep the cabinet level, preventing the cabinet 11 from tilting due to uneven ground, thus ensuring the installation stability and operational safety of the network cabinet.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
