Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to an explosion-proof switch. Background Art

[0002] A network switch is a device that expands a network and can provide more connection ports in a sub-network to connect more computers. It has the characteristics of high performance-price ratio, high flexibility, relative simplicity, and easy implementation.

[0003] For example, the authorization announcement number is CN217445382U, an explosion-proof network switch. The heat generated by the switch body is transferred to the heat conduction plate, and then heat exchange is carried out with the air through the heat dissipation fins to accelerate the heat discharge of the switch body. However, during the use of the switch in the above document, due to the lack of a fixing structure at the bottom of the switch in the above document, the switch cannot be fixed, which causes the switch in the above document to easily move when it is hit by an external impact, and easily causes the network port and the terminal of the switch in the above document to be pulled and loosened, thereby affecting the use of the switch;

[0004] Also, during use of the switch in the above document, since the filters on both sides of the switch in the above document cannot dry the external air, water molecules in the air can easily flow into the interior of the switch, which can easily cause short-circuit damage to the internal components of the switch, resulting in poor explosion-proof performance of the switch. Utility Model Content

[0005] The utility model aims to solve the problem that the switch body cannot be fixed and the air flowing into the switch cannot be dried, and proposes an explosion-proof switch.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An explosion-proof switch is designed, comprising a switch body and a network port, wherein a plurality of network ports are arranged at the front end of the switch body, the bottom end of the switch body is fixedly connected to a plurality of sleeves, the bottom end of the sleeves is fixedly connected to a suction cup, both sides of the switch body are fitted with a plurality of drying boxes, the two ends of the drying boxes are fixedly connected to a plurality of filter screens, a protective structure is arranged inside the drying box, and a fixing structure is arranged on the top of the sleeves.

[0008] Preferably, the fixing structure includes an I-shaped block, the outer wall of the I-shaped block is slidably connected to the sleeve, the bottom of the outer wall of the I-shaped block is fixedly connected to a rubber ring, the outer end of the rubber ring is tightly pressed against the sleeve, the top of the I-shaped block is slidably connected to the bottom protrusion, the ends of the protrusions on both sides are fixedly connected to the rotating rod, the middle part of the front end of the rotating rod is fixedly connected to one end of the torsion spring, and the outer wall of the protrusion at the top is slidably connected to the pressure block.

[0009] Preferably, the outer wall of the pressing block is slidably connected to the switch body, and the outer ends of the pressing blocks on both sides are fixedly connected to the connecting plate.

[0010] Preferably, the other end of the torsion spring is fixedly connected to the support rod, the middle part of the rotating rod is rotationally connected to the support rod, and the outer end of the support rod is fixedly connected to the switch body.

[0011] Preferably, the protective structure comprises a round rod, the middle parts of the round rods on both sides are rotatably connected to the drying box, the ends of the round rods are fixedly connected to the round blocks, the two sides of the round blocks are rotatably connected to the connecting rods through pins, the outer side of the connecting rods is rotatably connected to the vertical rods through pins, the outer ends of the vertical rods are fixedly connected to the limit blocks, the inner ends of the limit blocks are fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the drying box, and the outer walls of the plurality of vertical rods are slidably connected to the switch body.

[0012] Preferably, the middle portion of the outer wall of the limit block is slidably connected to the drying box, and the outer side of the outer wall of the limit block is snap-connected to the switch body.

[0013] The utility model provides an explosion-proof switch, which has the following beneficial effects: when the user presses the connection plates on both sides inward, the connection plates on both sides drive the top protrusions to move during the movement of the pressing blocks, the top protrusions drive the bottom protrusions to move in a circle through the rotating rod, and the bottom protrusions drive the rubber ring to move downward through the I-shaped block, and at the same time, the rotating rod drives the torsion spring to deform, and then the switch body is placed at a specified position, and the switch body is squeezed to squeeze the air inside the suction cup out, and then the connection plate is released, and the elastic force of the torsion spring drives the I-shaped block to move upward through the rotating rod, so that the cavity pressure between the I-shaped block and the sleeve is reduced, so that the external atmospheric pressure is pressed against the installation position by the squeezing suction cup, so as to fix the switch body, and avoid the situation that the switch is prone to movement when subjected to external impact, which may cause the network port and the wiring terminal to be pulled and loosened;

[0014] The user manually rotates the round rods on both sides, and the round rods drive the connecting rods on both sides to rotate through the round blocks. The connecting rods on both sides drive the corresponding limit blocks to move inward through the vertical rods on both sides. The drying box is then disassembled and the new drying box is connected to the switch body. The round rods are rotated in the same way. When the drying box is installed to the corresponding position, the round rods are released, and the elastic force of the spring resets the limit blocks, thereby fixing the drying box, thereby ensuring that the air flowing into the switch body is continuously dried, preventing humid air from entering the switch and causing short circuit explosions in internal components, thereby improving the explosion-proof performance of the switch.
