Description

Technical Field

[0001] The utility model relates to the technical field of network switches, in particular to a network switch with a dustproof function. Background Art

[0002] A switch is a network device used for forwarding electrical signals. It can connect user lines, telecommunication circuits and other functional units to be interconnected according to the request of a single user. A switch can provide an exclusive electrical signal path for any two network nodes connected to the switch. There is a MAC address table inside the switch, which records the corresponding information of all MAC addresses in the network and each port of the switch, so as to determine which port to forward from based on the destination MAC address of the data frame. Switches are widely used in various fields such as homes, offices, schools, hospitals, and enterprises to connect various network devices to achieve sharing and efficient transmission of network resources. During use, the switch needs to be placed in a well-ventilated place to facilitate the fan in the switch to work and transfer its internal heat to the external environment through the heat dissipation holes, thereby reducing the temperature inside the switch and enhancing the working stability of the switch.

[0003] With respect to the above-mentioned related technologies, the inventors have found that when the switch stops working, external dust can easily enter the inner cavity of the switch through the heat dissipation holes. Dust attached to electronic components can easily cause short circuits. However, when the existing switches stop working, the heat dissipation holes cannot be sealed, and dust can easily enter the inner cavity through the heat dissipation holes. Therefore, it is necessary to design a network switch that has the function of automatically sealing the heat dissipation holes when the switch stops working. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a network switch with a dustproof function. The rotary drive assembly drives the strip dust shield to rotate to a horizontal state, and heat is dissipated from between adjacent strip dust shields. After the network switch stops working, the strip dust shield returns to its initial vertical state under the action of its own gravity, and the rectangular heat dissipation holes are sealed. It has an automatic dustproof function, reduces the probability of damage due to short circuit caused by dust, and extends the service life.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a network switch with dustproof function, comprising: a switch body, both sides of the switch body are respectively provided with rectangular heat dissipation holes, and the inner cavities of the rectangular heat dissipation holes are respectively connected with dustproof mechanisms that can be opened and closed;

[0006] The dust-proof mechanism comprises a rectangular frame and a plurality of strip dust shield assemblies, wherein the strip dust shield assemblies comprise strip dust shields, a driving shaft and a driven shaft connected at both ends thereof, wherein the driving shaft and the driven shaft are close to the upper edge of the strip dust shields, and the outer ends of the driving shaft and the driven shaft are respectively passed through the rectangular frame and are rotatably connected thereto, and further comprises a rotation drive assembly that drives the driving shaft to drive the strip dust shields to rotate to a horizontal position;

[0007] A mounting frame is connected to the bottom of the switch body near the rectangular heat dissipation hole, and the mounting frame is respectively connected to a heat dissipation fan.

[0008] By adopting the above technical solution, when in use, the network switch is connected to an external power supply, the rotation drive component drives the active shaft to rotate, and the active shaft drives the strip dust shield to rotate to a horizontal state. There is a large heat dissipation cavity between adjacent strip dust shields. The heat dissipation fan absorbs the heat generated by the electronic components inside the switch body and transmits it to the outside, which has a high heat dissipation efficiency. After the network switch stops working, under the action of gravity of the strip dust shield, the strip dust shield rotates in the opposite direction to restore to the initial vertical state. The strip dust shield blocks the rectangular heat dissipation holes, thereby preventing external dust from entering the inner cavity of the switch body. It has an automatic dust-proof function, reduces the probability of damage due to short circuit caused by dust, and extends the service life.

[0009] In a preferred example, the utility model can be further configured as follows: the rotary drive assembly includes a rack and a driving gear respectively mounted on the driving shaft, the driving gear is meshingly connected to the rack, and also includes a guide member and a linear drive member driving the rack to move upward, the guide member is suitable for guiding the rack to move in the vertical direction.

[0010] By adopting the above technical solution, the linear drive member drives the rack to move upward, the rack drives the active gear to rotate, the active gear drives the active shaft to rotate, and the active shaft drives the strip dust shield to rotate to a horizontal state, so that a larger area of ​​heat dissipation cavity is provided between adjacent strip dust shields.

[0011] In a preferred example, the utility model can be further configured as follows: the guide member includes a waist-shaped hole arranged on the rack and two limit rods spaced apart and passing through the waist-shaped hole, and the outer end of the limit rod is spirally connected with a screw.

[0012] By adopting the above technical solution, the two limit rods slide in the waist-shaped hole to guide the rack to move in the vertical direction, so that the rack is meshed and connected with the driving gear. When the upper limit rod contacts the upper inner wall of the waist-shaped hole, the strip dust shield rotates to a horizontal state.

[0013] In a preferred example, the utility model can be further configured as follows: the linear drive component includes a magnet block and an electromagnet, the magnet block is connected to the lower end of the rack, the electromagnet is located below the magnet block, the end of the rectangular frame is connected to a horizontal plate, the electromagnet is connected to the horizontal plate and connected to an external power supply to drive the magnet block to move upward.

[0014] By adopting the above technical solution, after the electromagnet is connected to an external power supply, the electromagnet generates magnetism. At this time, a magnetic force of opposite poles repelling each other is generated between the electromagnet and the magnet block. The magnet block drives the rack to move upward, and finally the strip dust shield rotates to a horizontal state.

[0015] In a preferred example, the utility model can be further configured as follows: a strip-shaped counterweight block having a semicircular cross-section is connected to the inner surface of the strip-shaped dust shield near the lower edge.

[0016] By adopting the above technical solution, by connecting the strip-shaped counterweight block to the strip-shaped dust guard plate, the gravity of the strip-shaped dust guard plate is increased, so that the strip-shaped dust guard plate can be restored to its initial vertical state more smoothly.

[0017] In summary, the present invention includes at least one of the following beneficial technical effects:

[0018] 1. After the electromagnet is connected to an external power source, it generates magnetism. At this time, a magnetic force of opposite poles repelling each other is generated between the electromagnet and the magnet block. The magnet block drives the rack to move upward, and the rack drives the active gear to rotate. The active gear drives the active shaft to rotate, and the active shaft drives the strip dust shield to rotate to a horizontal state, so that there is a large area of ​​heat dissipation cavity between adjacent strip dust shields. The heat dissipation fan absorbs the heat generated by the electronic components inside the switch body and transmits it to the outside, which has a high heat dissipation efficiency.

[0019] 2. After the network switch stops working, the electromagnet is disconnected from the power supply, and there is no repulsive magnetic force between the electromagnet and the magnet block. Under the gravity of the strip dust shield and the strip counterweight, the strip dust shield rotates in the opposite direction to the initial vertical state. The strip dust shield blocks the rectangular heat dissipation holes, which has the function of automatic dust prevention, reduces the probability of damage due to short circuit caused by dust, and prolongs the service life.
