Technical Field

[0001] This invention relates to the field of switches, and in particular to a PoE switch. Background Technology

[0002] A PoE switch refers to a technology that, without modifying the existing Ethernet Cat.5 cabling infrastructure, can provide DC power to IP-based terminals such as IP phones, wireless LAN access points (APs), and network cameras while simultaneously transmitting data signals. PoE switches generate heat during operation; if this heat cannot be dissipated effectively, overheating can affect performance. Summary of the Invention

[0003] The purpose of this invention is to provide a PoE switch that can quickly dissipate heat and avoid overheating from affecting its use.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A PoE switch includes a body, pads disposed at the four corners of the lower end of the body, a frame connected to the upper end of the body, a fan bracket connected to the frame, and a fan installed in the fan bracket.

[0006] The pad is made of rubber.

[0007] The front end of the frame is provided with a light rod, the rear end of the frame is rotatably provided with a screw, the front end of the fan frame is slidably connected to the light rod, and the rear end of the fan frame is threadedly connected to the screw.

[0008] The frame is equipped with a micro motor on its side for driving the screw to rotate.

[0009] The upper end of the frame is provided with multiple crossbars evenly distributed.

[0010] It also includes square rods, pins, rotating plates, and leg rods. Two square rods are fixed to the rear end of the machine body, two pins are fixed to the rear end of the square rods respectively, the middle parts of the two rotating plates rotate on the two pins respectively, and the outer ends of the two rotating plates are vertically connected to the leg rods.

[0011] A disc is slidably mounted on the square rod. Multiple locking holes are evenly distributed on the disc. A locking pin is fixed to the front side of the rotating plate. A spring I is provided between the disc and the machine body, so that one of the locking holes on the disc slides onto the locking pin.

[0012] A connecting plate is fixed near the end of the rotating plate, and a connecting rod slides through the connecting plate. A pull seat is fixed to one end of the connecting rod and is fixedly connected to the leg. A baffle is fixed to the other end of the connecting rod, and a spring II is provided between the baffle and the connecting plate. A groove for holding the leg is provided on the side of the machine body.

[0013] The legs are covered with anti-slip rubber.

[0014] Two limiting rods are fixed at the lower end of the frame. Both limiting rods pass through the machine body and are connected to the machine body by a spring III, so that the frame is attached to the upper end of the machine body downward.

[0031] like Figure 1-12 As shown:

[0032] A PoE switch includes a body 101, pads 105 disposed at the four corners of the lower end of the body 101, a frame 201 connected to the upper end of the body 101, a fan bracket 205 connected to the frame 201, and a fan 206 installed in the fan bracket 205.

[0033] The main body 101 is placed on the table by four pads 105. When in use, the fan 206 is powered on and started, so that the fan blows air on the upper part of the main body 101 to dissipate heat, thereby effectively improving the heat dissipation efficiency of the main body 101 and avoiding overheating of the main body, which would affect its use.

[0034] Further:

[0035] The pad 105 is made of rubber.

[0036] By using rubber material, the stability of the body 101 when placed on the table via the four pads 105 is increased, while the shock resistance of the body 101 is also improved.

[0037] like Figure 1-12 As shown:

[0038] The front end of the frame 201 is provided with a light rod 203, and the rear end of the frame 201 is rotatably provided with a screw 204. The front end of the fan frame 205 is slidably connected to the light rod 203, and the rear end of the fan frame 205 is threadedly connected to the screw 204.

[0039] By rotating the screw 204, the fan bracket 205 can slide laterally on the guide rod 203, thereby adjusting and controlling the position of the fan bracket 205, which in turn adjusts and controls the position of the fan 206 blowing air, thus improving heat dissipation efficiency.

[0040] Further:

[0041] The frame 201 is equipped with a micro motor on its side for driving the screw 204 to rotate.

[0042] By controlling the micro motor, the micro motor drive screw 204 is made to rotate in both directions, thereby causing the screw drive fan frame 205 to move laterally back and forth within the frame 201, thus forming a uniform airflow for heat dissipation above the body 101, further improving heat dissipation efficiency.

[0043] like Figure 1-12 As shown:

[0044] The upper end of the frame 201 is provided with a plurality of crossbars 202 evenly distributed.

[0045] By setting multiple crossbars 202, a fence is formed at the upper end of the frame 201 to protect the movement path of the fan 206 and the fan bracket 205. At the same time, items can be placed on the multiple crossbars 202 to improve space utilization.

[0046] like Figure 1-12 As shown:

[0047] It also includes square rods 103, pins 104, rotating plates 301 and leg rods 405. Two square rods 103 are fixed to the rear end of the machine body 101, two pins 104 are respectively fixed to the rear end of the square rods 103, the middle part of the two rotating plates 301 rotates on the two pins 104 respectively, and the outer ends of the two rotating plates 301 are vertically connected to the leg rods 405.

[0048] By rotating the rotating plate 301, the leg 405 can be rotated around the pin 104. When the lower end of the leg 405 is lower than the height of the pad 105 and contacts the desktop, it will replace the pad 105 to form support for the entire switch. Moreover, as the rotating plate 301 rotates, the distance between the leg 405 and the lower end of the body 101 can be controlled, thereby adjusting the horizontal height of the body 101 and increasing the space between the body 101 and the desktop, further improving heat dissipation efficiency.

[0049] like Figure 1-12 As shown:

[0050] A disc 501 is slidably mounted on the square rod 103. The disc 501 is provided with a plurality of locking holes 503 evenly distributed on it. A locking pin 303 is fixed on the front side of the rotating plate 301. A spring I 502 is provided between the disc 501 and the machine body 101, so that one of the locking holes 503 on the disc 501 slides onto the locking pin 303.

[0051] To ensure the stability of the machine body 101 after the rotating plate 301 rotates and the height of the machine body 101 is adjusted by the leg rod 405, a disc 501 and a locking pin 303 are provided. The locking pin 303 is inserted into the corresponding locking hole 503 to lock the rotating plate 301, thereby ensuring the stability of the support provided by the leg rod 405 after the height of the machine body 101 is adjusted.

[0052] When adjustment is needed, press the disc 501 forward so that it overcomes the elastic force of the spring I 502 and moves forward on the square rod 103, thereby disengaging the locking hole 503 from the locking pin 303. Then, rotate the rotating plate 301. After the rotating plate 301 has rotated, release the disc 501. The elastic force of the spring I 502 will push the disc 501 closer to the rotating plate 301, thereby causing the locking pin 303 to be inserted into the corresponding locking hole 503 and locked again.

[0053] like Figure 1-12 As shown:

[0054] A connecting plate 302 is fixed to the end of the rotating plate 301 near the leg rod 405. A connecting rod 401 slides through the connecting plate 302. A pull seat 404 is fixed to one end of the connecting rod 401. The pull seat 404 is fixedly connected to the leg rod 405. A baffle 402 is fixed to the other end of the connecting rod 401. A spring II 403 is provided between the baffle 402 and the connecting plate 302. A groove 102 for holding the leg rod 405 is provided on the side of the machine body 101.

[0055] When the leg 405 needs to be retracted, the pull seat 404 is pulled to overcome the elastic force of the spring II 403 and move away from the rotating plate 301, thereby moving the leg 405 away from the rotating plate 301. The leg 405 can then rotate with the rotating plate 301 to the groove 102. At this time, the pull seat 404 is released, and the elastic force of the spring II 403 will push the pull seat 404 through the baffle 402 and the connecting rod 401 to move the leg 405 into the groove 102, thereby retracting the leg 405. This ensures that the switch is neat and tidy when the leg 405 is retracted, and occupies less space, making it easy to carry and package.

[0056] When in use, pull the leg 405 out of the groove 102 using the pull seat 404, and then rotate it to the appropriate position.

[0057] Further:

[0058] The leg bar 405 is covered with anti-slip rubber.

[0059] The anti-slip rubber design increases the stability of the machine body 101 when placed on the table via the leg bar 405, while also improving the shock resistance of the machine body 101.

[0060] like Figure 1-12 As shown:

[0061] Two limiting rods 207 are fixed at the lower end of the frame 201. Both limiting rods 207 pass through the body 101 and are provided with springs III 208 between them and the body 101, so that the frame 201 is attached downward to the upper end of the body 101. The rotating plate 301 is damped by an eccentric pin 602 at the end away from the leg 405. A clamping block 601 is fixed on the eccentric pin 602.

[0062] When items are placed on multiple crossbars 202, they will obstruct the space above the body 101, thereby reducing the heat dissipation effect of the body 101. At this time, the top clamping block 601 can be rotated around the eccentric pin 602 as the axis on the rotating plate 301 until the top clamping block 601 is in contact with the rear end of the body 101. Then, the rotating plate 301 is rotated downward so that the body 101 is supported by the leg bar 405. During this process, the rotating plate 301 will carry the top clamping block 601 upward and clamp the part of the frame 201 that protrudes from the body 101 at the rear end, so that the frame 201 slides upward on the body 101 through the two limit bars 207, thereby creating a gap between the frame 201 and the upper end of the body 101, so that there is space for heat dissipation at both the upper and lower ends of the body 101, ensuring the heat dissipation efficiency of the body 101, and at the same time ensuring that the body 101 supports the items through the frame 201. At this time, the switch is in the fully unfolded state.

[0063] Before rotating the rotating plate 301, the clamping block 601 can be rotated around the eccentric pin 602 as the axis. When the clamping block 601 is at its farthest distance from the rear end of the body 101, rotating the rotating plate 301 will only adjust the position of the leg rod 405, and the clamping block 601 will not contact the frame 201, thus continuing to ensure that the frame 201 is in contact with the upper end of the body 101.
