Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch with good heat dissipation performance. Background Art

[0002] With the continuous development of information technology, the demand for network communication in various fields is increasing day by day. As a key device in network communication, the importance of switches is self-evident. However, there are some problems with traditional switches. In terms of heat dissipation, the early switches had poor heat dissipation performance. Since a large number of electronic components are integrated inside the switch, a lot of heat will be generated during operation. Traditional switches may not have a specially optimized heat dissipation design, such as the lack of an effective air duct structure. This may cause heat to accumulate inside the switch and cannot be dissipated in time, resulting in an increase in the device temperature. When the temperature is too high, it will affect the performance and lifespan of electronic components, and may cause the switch to operate unstably, resulting in data transmission errors, lags or even crashes. In terms of scalability, the expansion ability of previous switches was limited. With the continuous expansion of the network scale and the increase in the number of devices, the demand for the number of switch communication interfaces is also increasing. Traditional switches may not be easily expandable, or the expansion method is relatively complex. For example, some old switches may need to replace the entire device to increase the number of interfaces, which is costly and inconvenient to operate. Moreover, for some network layouts with special requirements, traditional switches may be difficult to flexibly adapt to different connection and expansion requirements. In terms of cable management, the cable management of past switches was not perfect. There are many cables connected to the switch in the network. Traditional switches may not have effective cable sorting and fixing measures. This easily leads to messy cables, which is not only unsightly, but may also affect the stability of network connection and communication quality due to problems such as loose or entangled cables. At the same time, messy cables will also bring difficulties to the maintenance and troubleshooting of the device, increasing the maintenance cost and time. To solve these problems, it is very necessary to develop a switch with good heat dissipation performance, strong scalability and good cable management function. Publication No.: CN208434068U discloses a switch, including a case, a switch circuit disposed in the case, and a plurality of first switch communication interfaces disposed on the front surface of the case; it further includes a flexible connecting plate and an expansion board, the expansion board is rotatably connected to the front surface of the case through the flexible connecting plate in a foldable manner, a metal trace is disposed on the flexible connecting plate, and a plurality of second switch communication interfaces are disposed on the expansion board, and the plurality of second switch communication interfaces are connected to the switch circuit through the metal trace. However, for the above device, the device dissipates heat through heat dissipation holes. During the use of the device, the heat dissipation effect is low, and long-term use may cause the device to be damaged due to heat accumulation and needs to be improved. Content of the Utility Model

[0003] The purpose of the present utility model is to solve the technical problems raised in the above-mentioned background technology.

[0004] The present utility model adopts the following technical solutions: A switch with good heat dissipation performance, including a body, a top plate is sleeved on the top of the body, an extension board one is placed at the fitting position at the rear end of the body, one end of the extension board one is rotatably connected to an extension board two, communication interfaces are opened on the surfaces of the extension board one, the extension board two and the rear end of the body, air ducts are opened inside both ends of the body, heat dissipation holes are fixedly installed at the front end of the air ducts, a placement groove is opened on one side at the rear end of the air ducts, a micro motor is fixed inside the placement groove, a fan blade is fixedly installed at the output end of the micro motor, and an air outlet board is fixedly installed at the rear end of the placement groove.

[0005] Preferably, the top plate and the top of the body are fixed by bolts. Here, the top plate and the top of the body are fixed by bolts. This fixing method is firm and reliable, ensuring that the top plate will not loosen or fall off easily during normal use, and can effectively protect the components inside the body from external dust, sundries, etc. At the same time, when it is necessary to open the top plate, bolt fixing is also convenient for disassembly and installation.

[0006] Preferably, the rear end of the body and the surface of the extension board one are fixed by bolts, and screw holes are opened on the surface of the extension board two. Here, the rear end of the body and the extension board one are fixed by bolts, ensuring the stability and reliability of the extension board one during use, and it will not move or separate from the body easily due to external forces, etc., ensuring the stability of the communication interface connection. Screw holes are opened on the surface of the extension board two, which is convenient for further fixing the extension board two or connecting it with other components, improving the flexibility of use and the convenience of installation of the extension board two.

[0007] Preferably, the connection between the placement groove and the air duct is arc-shaped. Here, the connection between the placement groove and the air duct is arc-shaped. This design can reduce the resistance of the air flowing in the air duct, enabling the airflow generated by the micro motor driving the fan blade to pass through the air duct more smoothly, improving the heat dissipation efficiency, and at the same time reducing the noise generated during the airflow movement, creating a relatively quiet working environment.

[0008] Preferably, fixing blocks are fixedly installed on the surfaces of the first extension board and the second extension board. A bidirectional positive and reverse lead screw is sleeved inside the fixing block. Clamping blocks are threadedly connected to the surface of the bidirectional positive and reverse lead screw, and a rotating block is fixedly installed at the top end of the bidirectional positive and reverse lead screw. Here, the structure of the bidirectional positive and reverse lead screw, the clamping blocks threadedly connected thereto, and the rotating block at the top end inside the fixing blocks on the surfaces of the first extension board and the second extension board can drive the bidirectional positive and reverse lead screw to rotate by rotating the rotating block, causing the clamping blocks to move, which can clamp or loosen cables connected to the communication interfaces, etc., playing a role in organizing and fixing the cables, preventing the cables from being in a mess, and preventing the communication quality from being affected or potential safety hazards from being caused due to the cables being loose or entangled.

[0009] Preferably, a silica gel pad is fixedly installed on the surface of the clamping block. Here, the silica gel pad fixedly installed on the surface of the clamping block can, on the one hand, increase the friction between the clamping block and the cable, making the cable fixed more firmly. On the other hand, the silica gel pad has a soft texture and can protect the surface of the cable from being scratched or damaged by the clamping block, ensuring the integrity and service life of the cable.

[0010] Preferably, anti-slip lines are provided on the surface of the rotating block. Here, the anti-slip lines provided on the surface of the rotating block increase the friction between the finger and the rotating block. When rotating the rotating block to operate the clamping block to clamp or loosen the cable, it is more convenient and accurate to apply force, preventing the finger from slipping, improving the convenience and accuracy of the operation, and making the operation of organizing and fixing the cable more efficient.

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a switch with good heat dissipation performance, including a body 1, a top plate 2 is sleeved on the top end of the body 1, a first expansion board 3 is placed at the fitting part of the rear end of the body 1, one end of the first expansion board 3 is rotatably connected to a second expansion board 4, communication interfaces 5 are opened on the surfaces of the first expansion board 3, the second expansion board 4, and the rear end of the body 1, air ducts 6 are opened inside both ends of the body 1, heat dissipation holes 7 are fixedly installed at the front end of the air ducts 6, a placing groove 8 is opened at one side of the rear end of the air ducts 6, a micro - motor 9 is fixed inside the placing groove 8, a fan blade 10 is fixedly installed at the output end of the micro - motor 9, and an air outlet plate 11 is fixedly installed at the rear end of the placing groove 8. By starting the micro - motor 9, the micro - motor 9 drives the fan blade 10 to rotate, and the air flow generated by the rotation of the fan blade 10 enters the device through the air duct 6, so as to dissipate heat from the device.

[0024] Please refer toFigures 1-4 The top plate 2 is fixed to the top end of the body 1 by bolts, and the rear end of the body 1 is fixed to the surface of the first extension plate 3 by bolts. A screw hole 12 is provided on the surface of the second extension plate 4. The connection between the placement groove 8 and the air duct 6 is arc-shaped. A silica gel pad 17 is fixedly installed on the surface of the clamping block 15, and an anti-slip groove 18 is provided on the surface of the rotating block 16. By providing the anti-slip groove 18, it is convenient for the staff to clamp and fix the cable.

[0025] Embodiment 2

[0026] Please refer to Figures 1-4 On the surfaces of the first extension plate 3 and the second extension plate 4, fixing blocks 13 are fixedly installed. A bidirectional positive and negative lead screw 14 is sleeved inside the fixing block 13. A clamping block 15 is threadedly connected to the surface of the bidirectional positive and negative lead screw 14. A rotating block 16 is fixedly installed at the top end of the bidirectional positive and negative lead screw 14. By rotating the rotating block 16, the rotation of the rotating block 16 drives the bidirectional positive and negative lead screw 14 to rotate. Then, the rotation of the bidirectional positive and negative lead screw 14 drives the clamping block 15 to move, and the cable can be clamped and fixed.

[0027] Working principle: First, for communication connection, the cable of the network device is connected to the communication interfaces 5 on the rear end surfaces of the body 1, the first extension plate 3, and the second extension plate 4 to achieve data communication. The first extension plate 3 is placed in contact with the body 1, and the second extension plate 4 can be rotated to adjust the position, increasing the number of communication interfaces 5 and the range of devices that can be connected. Next is the heat dissipation work. When the internal electronic components of the switch generate heat during operation, the micro motor 9 starts to drive the fan blade 10 to rotate to generate air flow. The air flow enters the air duct 6 from the placement groove 8 on one side of the rear end of the air duct 6. Since the connection between the placement groove 8 and the air duct 6 is arc-shaped, the resistance of the air flow is reduced. After the air flow flows through the air duct 6 and takes away the heat, it is discharged through the heat dissipation holes 7 at the front end of the air duct 6. The air outlet plate 11 at the rear end of the placement groove 8 guides and protects the air flow. Finally, for cable arrangement and fixation, by rotating the rotating block 16 at the top end of the bidirectional positive and negative lead screw 14 inside the fixing block 13 on the surfaces of the first extension plate 3 and the second extension plate 4, the rotation of the bidirectional positive and negative lead screw 14 drives the movement of the clamping block 15 that is threadedly connected. The clamping block 15 can clamp or loosen the cable. The silica gel pad 17 on the surface of the clamping block 15 not only increases the friction with the cable to make the fixation more firm, but also protects the surface of the cable from being scratched or damaged, playing a role in arranging and fixing the cable and avoiding the chaos of the cable from affecting the communication quality or causing potential safety hazards.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
