Description

Technical Field

[0001] This utility model relates to the field of hub technology, specifically to a USB port protection structure for a hub. Background Technology

[0002] The English term for a hub is "Hub." "Hub" means "center," and the main function of a hub is to regenerate, shape, and amplify received signals to extend the network's transmission distance, while simultaneously concentrating all nodes around it. It operates at Layer 1 of the OSI (Open Systems Interconnection) reference model, the "physical layer." Like network interface cards (NICs) and network cables, hubs are fundamental devices in local area networks (LANs), employing the CSMA / CD (Carrier Sense Multiple Access with Collision Detection) media access control mechanism. Each hub interface simply transmits and receives bits; if a 1 is received, it forwards a 1, and if a 0 is received, it forwards a 0, without collision detection.

[0003] The prior art, disclosed in CN214673278U, provides a USB hub with charging functionality, comprising a hub body, a USB port, a fixed connecting plate, a cable winding protective cup, a protective plate, and a rotating disk. The hub body has a USB port on its front side, a fixed connecting plate on its lower side, a cable winding protective cup mounted on its lower side, a fixed bracket mounted on the upper side inside the cable winding protective cup, a rotating groove inside the fixed bracket, a rotating disk mounted on the lower side of the cable winding protective cup, a protective plate mounted on the upper side of the rotating disk, a first slot inside the protective plate, a locking block on the lower side of the annular side of the cable winding protective cup, and a cable winding post mounted on the upper side of the rotating disk. This design solves the problem that the data cable length of existing USB hubs with charging functionality cannot be adjusted. This utility model has a reasonable structure, facilitates the adjustment of the data cable length, and has good performance.

[0004] With the above configuration, the existing hub, comprising a hub body, USB port, fixed connection plate, cable protection cup, protective plate, rotating disk, USB plug, fixed bracket, rotating slot, rotating chuck, data connection cable, cable winding post, cable exit guide tube, first slot, card block, and second slot, allows for convenient adjustment of the data connection cable length of the USB hub. This solves the problem that the data connection cable length of existing USB hubs with charging functions cannot be adjusted, thus improving the practicality of this invention. However, the existing hub has the following drawbacks during operation:

[0005] When using the hub described in the prior art, the data cable needs to be inserted into the USB port. However, when the hub is not in use, the data cable needs to be unplugged from the USB port, exposing the USB port to the air. Over time, due to temperature changes in the air, dust and moisture can enter the USB port, easily damaging it. In addition, some insects may crawl into the USB port, causing short circuits and unstable connections when the data cable is inserted, which can easily damage the hub. Utility Model Content

[0006] This utility model aims to provide a protective structure for the USB port of a hub, mainly to solve the technical problem that the USB plug on the hub is exposed to the air, which makes it easy for dust, moisture and insects in the air to crawl into the USB port and damage the hub.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A USB port protection structure for a hub includes a hub body. Symmetrical fixing grooves are formed on the upper surface of the hub body. A spring shaft is fixedly connected inside the fixing groove. A rotating block is fixedly attached to the outer wall of the spring shaft. A protective plate is fixedly attached to the lower surface of the rotating block at the end away from the spring shaft. The protective plate is in contact with the USB port of the hub body. A limit block is fixedly attached to the end of the rotating block away from the spring shaft. A movable groove is formed on the inner wall of the fixing groove. A limit component is installed inside the movable groove. Symmetrical sliding grooves are formed on the upper surface of the hub body. Protective components are installed on the inner wall of the sliding grooves.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the USB port needs to be used, first adjust the protective component so that the protective shell moves to the other side. Then pull the pull block, so that the pull block moves the protective plate. The protective plate moves the rotating block, which drives the spring shaft to rotate, turning the limit block to abut against the limit rod. At this time, the limit block squeezes the limit rod, so that the limit rod retracts into the movable groove. When the rotating block abuts against the bottom surface of the fixed groove, the limit rod is locked with the limit groove under the action of the spring, completing the operation.

[0011] 2. Beneficial effects:

[0012] Existing technology, by incorporating a hub body, USB port, fixed connecting plate, cable protection cup cover, protective plate, rotating disk, USB plug, fixed bracket, rotating slot, rotating chuck, data connection cable, winding post, cable guide tube, first slot, card block, and second slot, allows for convenient adjustment of the data connection cable length of the USB hub. This solves the problem of the inability to adjust the data connection cable length in existing USB hubs with charging functions, thus improving the practicality of this invention. However, existing hubs require the data connection cable to be inserted into the USB port during use, but must be unplugged when not in use, leaving the USB port exposed to air. Over time, this exposure can lead to corrosion and other defects. Changes in air temperature can allow dust and moisture to enter the USB port, easily damaging it. Insects can also crawl inside, causing short circuits and unstable connections when data cables are inserted, potentially damaging the hub. This solution addresses this by using a protective plate, a rotating block, and a limiting component. The protective plate prevents dust from entering the USB port. Pulling the protective plate rotates the rotating block, which in turn rotates the limiting block. Ultimately, the limiting slot on the limiting block engages with the limiting rod of the limiting component, opening the protective plate. The operation is very simple, and the protective plate effectively prevents dust and insects from entering the USB port, thus preventing damage.

[0013] Preferably, the limiting component includes a limiting rod that is slidably connected to a movable groove. A limiting groove is formed on one side of the limiting block, and the limiting rod is inserted into the limiting groove. A spring is fixedly connected to the inner wall of the movable groove, and the other end of the spring is fixedly connected to the limiting rod. Symmetrical pull grooves are formed on the upper surface of the hub body, communicating with the movable groove. A pull rod is fixedly connected to the outer wall of the limiting rod, passing through the pull groove and slidably connected to it. By setting the limiting component, the protective plate can be prevented from rebounding and hitting the data cable when it is inserted into the USB port, preventing the data cable from detaching from the USB port and causing damage. Inserting the data cable is also more convenient and faster.

[0014] Preferably, the protective component includes a protective shell, a slider fixedly attached to the bottom surface of the protective shell, the slider being slidably connected to the inner wall of a groove, and symmetrical support grooves formed on the inner wall of the groove. Support blocks are slidably connected to the inner walls of the support grooves, and the support blocks are fixedly connected to the slider. By setting up the protective component, dust and water can be prevented from falling into the fixed groove, thus preventing damage to the USB port.

[0015] Preferably, the end of the limiting rod away from the spring is sloped. This ensures that the limiting rod does not obstruct the movement of the limiting block when the protective plate is opened, making it easier and faster for the limiting rod to insert into the limiting groove without requiring adjustment of the limiting components, making it very convenient to use.

[0016] Preferably, the upper surface of the protective case has protective textured patterns. This increases the friction between the fingers and the protective case, preventing slippage.

[0017] Preferably, a pull block is fixed to the side of the protective plate away from the hub body, and a rubber pad is fixed to the outer wall of the pull block. This facilitates pulling the protective plate and increases the friction between the fingers and the pull block. Attached Figure Description

[0026] When the USB port needs to be used, first pull the protective shell 13, causing the protective shell 13 to move the slider 14. The slider 14 then moves the support block 16, moving the protective shell 13 away from the fixed groove 2. Then pull the pull block 18, causing the pull block 18 to move the protective plate 5. The protective plate 5 then moves the rotating block 4, which in turn rotates the spring shaft 3, causing the limiting block 6 to abut against the limiting rod 9. At this time, the limiting block 6 presses against the limiting rod 9, and the limiting rod 9 presses against the spring 10, causing the limiting rod 9 to retract into the movable groove 7. When the rotating block 4 abuts against the bottom surface of the fixed groove 2, the limiting rod 9 is engaged with the limiting groove 17 under the action of the spring 10. When it is necessary to close the protective shell 13, pull the pull rod 12, causing the limiting rod 9 to disengage from the limiting groove 17. Then, one side of the protective plate 5 abuts against the USB port under the action of the spring 10. Finally, pull the protective shell 13 to protect the fixed groove 2, completing the operation.
