Description

Technical Field

[0001] This utility model relates to the field of network switch technology, and more specifically, to a stackable network switch. Background Technology

[0002] In modern network architectures, network switches are the core devices for building local area networks (LANs). As network size increases and bandwidth demands rise, traditional single switches often fall short in terms of port count and processing capacity. Stacking technology connects multiple physical switches using dedicated stacking cables or ports, allowing them to be logically managed as a single device, thereby expanding port density, increasing bandwidth, and enhancing redundancy.

[0003] When traditional network switches are stacked in a cabinet, they generally rely on external brackets or screws for fixing. The installation and disassembly process is cumbersome and the maintenance efficiency is low. In high-density stacking scenarios, the heat dissipation space inside the cabinet is limited, and heat is easy to accumulate, causing the internal temperature of the equipment to rise. This can lead to overheating and frequency reduction of core chips, performance degradation, or even hardware damage, which restricts the long-term stable operation of the network system. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a stackable network switch. It solves the problem that traditional network switches, when stacked in a cabinet, generally rely on external brackets or screws for fixing, which makes the installation and disassembly process cumbersome and maintenance inefficient. In high-density stacking scenarios, the heat dissipation space inside the cabinet is limited, and heat is easily accumulated, causing the internal temperature of the equipment to rise, leading to overheating and frequency reduction of core chips, performance degradation, and even hardware damage, thus restricting the long-term stable operation of the network system.

[0005] To achieve the above objectives, this utility model provides a stackable network switch, including a network switch body, four first mounting bases and four second mounting bases symmetrically mounted on the network switch body, each first mounting base having an insertion block fixedly connected to it, each second mounting base having an insertion slot fixedly connected to it, each insertion slot having a positioning block, both the insertion block and the positioning block having an inclined surface, each insertion block having a positioning opening, and each insertion slot having an elastic structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This embodiment provides a stackable network switch, including a network switch body 1. Considering that traditional network switches, when stacked in a rack, generally rely on external brackets or screws for fixing, the installation and disassembly process is cumbersome and maintenance efficiency is low. In high-density stacking scenarios, the heat dissipation space inside the rack is limited, heat easily accumulates, causing the internal temperature of the device to rise, leading to overheating and frequency reduction of the core chip, performance degradation, and even hardware damage, thus restricting the long-term stable operation of the network system. The network switch body 1 has four symmetrical first mounting bases 2 and four second mounting bases 3. Each first... Each mounting base 2 is fixedly connected to an insertion block 4, each second mounting base 3 is fixedly connected to an insertion slot 5, and each insertion slot 5 is provided with a positioning block 6. Both the insertion block 4 and the positioning block 6 are inclined. Each insertion block 4 has a positioning opening. Each insertion slot 5 is provided with an elastic structure, which includes two sliding plates 8 symmetrically fixedly connected to the positioning block 6. The opposite ends of the two sliding plates 8 are slidably connected to the inner wall of the insertion slot 5. Each sliding plate 8 is fixedly connected to a spring 9, and the opposite end of each spring 9 is fixedly connected to the inner wall of the insertion slot 5.

[0022] In summary, the improvement of this embodiment lies in:

[0023] The inclined design of the insertion block 4 and the positioning block 6 guides the equipment to automatically align, eliminating the need for manual fine-tuning. The positioning block 6, driven by the spring 9, snaps into the positioning port of the insertion block 4, forming a vibration-resistant rigid connection and improving stacking stability.

[0024] Based on the above, other structures also need to be disclosed in detail, such as:

[0025] Please see Figure 3 and Figure 4 The insertion slot 5 has a connection port, the positioning block 6 passes through the connection port and is fixedly connected to the connecting plate 7. Multiple workers can pull the connecting plate 7 simultaneously to pull the positioning block 6 out of the positioning port, lift the network switch body 1 above, and disassemble the network switch body 1.

[0026] Please see Figure 1 and Figure 2Considering that the stacked network switch body 1 will dissipate a lot of heat when working, two heat-conducting copper plates 10 are symmetrically fixedly connected on the network switch body 1. Each heat-conducting copper plate 10 is fixedly connected with a heat dissipation fin 11. When the chip inside the network switch body 1 generates heat, the heat is conducted to the heat-conducting copper plates 10 on both sides. The copper plates 10 diffuse the heat to the heat dissipation fin 11, and the air flows through the heat dissipation fin 11 to carry away the heat.

[0027] Please see Figure 1 and Figure 2 The network switch body 1 has symmetrically arranged heat dissipation vents, and filter plates 12 are installed at the heat dissipation vents. The filter plates 12 prevent dust from entering, ensuring heat dissipation efficiency and extending service life.

[0028] Please see Figure 1 and Figure 2 The first mounting base 2 and the second mounting base 3 are fixedly mounted on the main body 1 of the network switch by means of the first fixing bolt 13, and the filter plate 12 is fixedly mounted on the main body 1 of the network switch by means of the second fixing bolt 14.

[0029] In summary, the working principle of this solution is as follows:

[0030] When the network switch bodies 1 are stacked one on top of the other, the guide inserts the upper network switch body 1 into the insertion slot 5 of the lower network switch body 1. The inclined guide automatically corrects the position. The insert block 4 squeezes the inclined surface of the positioning block 6, forcing the positioning block to retract into the slot and compress the spring 9. When the insert block is fully inserted, the positioning block 6 pops out under the action of the spring's restoring force and locks into the positioning hole of the insert block, thus achieving mechanical interlocking.

[0031] The internal chip of the network switch body 1 generates heat, which is conducted to the heat-conducting copper plates 10 on both sides. The copper plates 10 diffuse the heat to the heat dissipation fins 11. Air flows through the heat dissipation fins 11 and carries away the heat. The side heat dissipation vents introduce airflow, and the filter plate 12 blocks dust from entering, ensuring heat dissipation efficiency and extending lifespan.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
