Description

Technical Field

[0001] The utility model relates to the technical field of dust covers, in particular to a detachable dust cover for computer network equipment. Background Technique

[0002] Network equipment refers to the hardware equipment used to establish, manage, and maintain computer networks. They help connect computers, servers, terminal devices, and other network equipment so that they can communicate with each other and exchange data. The types of network equipment include routers, switches, hubs, gateways, firewalls, network cards, etc. These devices work at different network layers (such as the physical layer, data link layer, network layer, transport layer, etc.) to ensure the normal operation of the network and the effective transmission of data.

[0003] Currently, when a switch is in use, dust in the air easily enters the device through the heat dissipation holes on both sides. The dust may accumulate on the surface of electronic components or connectors, resulting in failures or short circuits of the electronic components, reducing the performance of the device or even causing it to completely fail. Moreover, the dust in the air may fall into the slots, causing interference or loss of signal transmission, and then there may be unstable network connections or even packet loss. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detachable dust cover for computer network equipment that can prevent dust from entering the switch through the heat dissipation holes and prevent dust from falling into the slots.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A detachable dust cover for computer network equipment includes a body. Heat dissipation holes are provided on both side surfaces of the body. A power jack and a plurality of slots are arranged on the surface of the body. A U-shaped dust cover is arranged outside the body, and installation mechanisms are arranged at both ends of the U-shaped dust cover. A rear side plate is installed on the side surface of the U-shaped dust cover. A hole and a slot are respectively provided on the rear side plate corresponding to the power jack and the slots. Sealing plates are arranged on the outer surface of the rear side plate on both the upper and lower sides of the slot. A plugging mechanism capable of driving the two sealing plates to move in opposite directions simultaneously is arranged on the outer surface of the rear side plate.

[0007] It can be seen that through the setting of the U-shaped dust cover, the heat dissipation holes on both sides of the machine body can be dust-proofed, preventing dust from entering the interior of the machine body. Moreover, the U-shaped dust cover itself has air permeability, so it does not affect the heat dissipation effect of the heat dissipation holes. In addition, the U-shaped dust cover can also prevent dust from falling on the surface of the machine body. Through the setting of the installation mechanism, it is convenient to disassemble and clean the U-shaped dust cover to ensure its use effect. Through the setting of the blocking mechanism, when the slot is not in use, the two sealing plates can be used to close it, thus preventing dust from entering and causing interference or loss of signal transmission, which may lead to unstable network connection or even loss of data packets. And after the plug is inserted into the slot, the blocking mechanism can also drive the two sealing plates to clamp the plug to ensure the stability of the plug connection and avoid data interruption caused by loosening.

[0008] Further, the installation mechanism includes an L-shaped plate installed at the bottom of the U-shaped dust cover. A clamping plate is arranged inside the L-shaped plate. A first screw rod penetrates through and is threadedly connected to the inside of the L-shaped plate, and the end of the first screw rod is rotatably connected to the clamping plate. Limiting rods are connected to both sides of the outer surface of the clamping plate, and the ends of the limiting rods penetrate through the inside of the L-shaped plate.

[0009] When installing the U-shaped dust cover, first put the U-shaped dust cover on the outside of the machine body so that the notch and the hole are respectively corresponding to the slot and the power jack. Then rotate the first screw rod. Due to the limiting effect of the limiting rods, the clamping plate can move vertically towards the machine body and press tightly against its bottom, thus achieving the purpose of fixing the U-shaped dust cover. When disassembling, only need to rotate the first screw rod in the reverse direction to drive the clamping plate to separate from the bottom of the machine body, and then pull out the U-shaped dust cover from the machine body, which is convenient for disassembly.

[0010] Further, the blocking mechanism includes two side blocks installed on the outer surface of the rear side plate. A second screw rod with a pair of reverse threads is rotatably connected between the two side blocks. Nuts are respectively installed on the two reverse threads of the second screw rod. A connecting block is connected to the outer surface of the nut, and the end of the connecting block is connected to the sealing plate.

[0011] After the plug is inserted into the slot from the notch, the second screw rod can be rotated. Due to the setting of the reverse threads, the two nuts can move inward simultaneously, and through the connection of the connecting blocks, drive the two sealing plates to move inward and clamp on the surface of the plug, achieving the purpose of fixing the plug and avoiding loosening. When the slot is not in use, the two sealing plates can be driven to close each other by rotating the second screw rod, so that the slot can be closed to prevent dust from entering.

[0012] Further, a sliding groove is opened on the outer surface of the rear side plate. Sliding blocks are installed on the outer surfaces of the two nuts, and the ends of the two sliding blocks are arranged in the sliding groove.

[0013] Through the setting of the sliding groove and the sliding block, the stability and smoothness of the movement of the nut can be improved.

[0014] Furthermore, knobs are installed at the ends of the second screw and the first screw, and anti-slip patterns are provided on the outer surfaces of the knobs.

[0015] Through the settings of the knobs and the anti-slip patterns, the rotation operations of the second screw and the first screw can be facilitated, and the occurrence of hand slipping can be effectively prevented.

[0016] Furthermore, four feet are installed at the bottom of the body, and the four feet are respectively arranged at the four corners of the bottom of the body.

[0017] Through the settings of the feet, when the body is placed on a plane, a gap is left between its bottom and the plane, so that heat can be discharged outward, which is beneficial to the heat dissipation effect.

[0018] Furthermore, the materials of the U-shaped dust cover and the rear side plate are both stainless steel.

[0019] Stainless steel has good strength and corrosion resistance, so its service life can be extended.

[0020] Furthermore, a rubber pad is arranged on the side of the clamping plate facing the body, and anti-slip patterns are provided on the outer surface of the rubber pad.

[0021] Through the settings of the rubber pad and the anti-slip patterns, the friction between the clamping plate and the body can be increased, so as to improve the installation effect of the U-shaped dust cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The present utility model will be described in detail below in conjunction with the accompanying drawings.

[0028] As Figures 1-4 shown, a detachable dust-proof cover for a computer network device includes a body 100. Heat dissipation holes are provided on both side surfaces of the body 100. A power jack 102 and a plurality of slots 101 are provided on the surface of the body 100. A U-shaped dust-proof cover 103 is provided outside the body 100. Mounting mechanisms 200 are provided at both ends of the U-shaped dust-proof cover 103. A rear side plate 104 is mounted on the side surface of the U-shaped dust-proof cover 103. A hole 106 and a slot 105 are respectively provided on the rear side plate 104 corresponding to the power jack 102 and the slots 101. Sealing plates 107 are provided on both the upper and lower sides of the outer surface of the rear side plate 104 at the slot 105. A plugging mechanism 300 capable of driving the two sealing plates 107 to move in opposite directions simultaneously is provided on the outer surface of the rear side plate 104.

[0029] During use, first put the U-shaped dust-proof cover 103 on the outside of the body 100, and make the slot 105 and the hole 106 correspond to the slot 101 and the power jack 102 respectively. Then fix the U-shaped dust-proof cover 103 on the outside of the body 100 through the mounting mechanism 200. The U-shaped dust-proof cover 103 can protect the heat dissipation holes on both sides of the body 100, prevent dust from entering, and ensure the air circulation without affecting the normal heat dissipation of the body 100. Then pass the power plug through the hole 106 and insert it into the power jack 102, and pass the data plug through the slot 105 and insert it into the slot 101. Then, under the action of the plugging mechanism 300, drive the two sealing plates 107 to approach each other and clamp on both sides of the data plug to fix the data plug, thereby avoiding the situation of connection interruption caused by the loosening of the data plug during use and ensuring the stability of data transmission. And when the slot 101 is not in use, the plugging mechanism 300 can be used to drive the two sealing plates 107 to close each other, so as to close the slot 101 and prevent dust from entering.

[0030] Specifically, the installation mechanism 200 includes an L-shaped plate 201 installed at the bottom of the U-shaped dust cover 103. A clamping plate 202 is arranged on the inner side of the L-shaped plate 201. A first screw rod 203 penetrates through and is threadedly connected to the inside of the L-shaped plate 201, and the end of the first screw rod 203 is rotatably connected to the clamping plate 202. Limit rods 204 are connected to both sides of the outer surface of the clamping plate 202. The ends of the limit rods 204 penetrate through the inside of the L-shaped plate 201. When installing the U-shaped dust cover 103, first put the U-shaped dust cover 103 on the outside of the machine body 100, so that the notch 105 and the hole 106 correspond to the slot 101 and the power jack 102 respectively. Then rotate the first screw rod 203. Due to the limiting effect of the limit rods 204, the clamping plate 202 can move vertically towards the machine body 100 and press tightly against its bottom, thereby achieving the purpose of fixing the U-shaped dust cover 103. When disassembling, only need to rotate the first screw rod 203 in the reverse direction to drive the clamping plate 202 to separate from the bottom of the machine body 100, and then pull out the U-shaped dust cover 103 from the machine body 100, which is convenient for disassembly.

[0031] Specifically, the blocking mechanism 300 includes two side blocks 301 installed on the outer surface of the rear side plate 104. A second screw rod 302 with a pair of reverse threads is rotatably connected between the two side blocks 301. Nuts 303 are respectively installed on the two reverse threads of the second screw rod 302. A connecting block 304 is connected to the outer surface of the nut 303. The end of the connecting block 304 is connected to the sealing plate 107. After the plug is inserted into the slot 101 from the notch 105, the second screw rod 302 can be rotated. Due to the setting of the reverse threads, the two nuts 303 can move inwards simultaneously, and through the connection of the connecting block 304, drive the two sealing plates 107 to move inwards and clamp on the surface of the plug, achieving the purpose of fixing the plug and preventing loosening. When the slot 101 is not in use, the two sealing plates 107 can be driven to close each other by rotating the second screw rod 302, thereby closing the slot 101 and preventing dust from entering.

[0032] Specifically, a chute 400 is opened on the outer surface of the rear side plate 104. Sliders 401 are installed on the outer surfaces of the two nuts 303, and the ends of the two sliders 401 are arranged in the chute 400. Through the setting of the chute 400 and the slider 401, the stability and smoothness of the movement of the nut 303 can be improved.

[0033] Specifically, knobs 500 are installed at the ends of the second screw rod 302 and the first screw rod 203. Anti-slip patterns are opened on the outer surfaces of the knobs 500. Through the setting of the knobs 500 and the anti-slip patterns, the rotation operation of the second screw rod 302 and the first screw rod 203 can be facilitated, and the occurrence of hand slipping can be effectively prevented.

[0034] Specifically, four feet 600 are installed at the bottom of the body 100, and the four feet 600 are respectively arranged at the four corners of the bottom of the body 100. Through the arrangement of the feet 600, when the body 100 is placed on a plane, there is a gap between its bottom and the plane, so that heat can be discharged outward, which is beneficial to the heat dissipation effect.

[0035] Specifically, the materials of the U-shaped dust cover 103 and the rear side plate 104 are both stainless steel. Stainless steel has good strength and corrosion resistance, so its service life can be extended.

[0036] Specifically, a rubber pad is arranged on the side of the clamping plate 202 facing the body 100, and anti-slip lines are arranged on the outer surface of the rubber pad. Through the arrangement of the rubber pad and the anti-slip lines, the friction between the clamping plate 202 and the body 100 can be increased, and the installation effect of the U-shaped dust cover 103 can be improved.
