Abstract

This utility model relates to the field of USB technology, specifically a USB interface device, comprising: a housing including a USB connector with a data cable disposed on its surface; and a protective mechanism including a slider acting on the surface of the USB connector, with a connecting block fixedly connected to the surface of the slider. This utility model, through the connection between the USB connector and the slider, allows the movable slider to expose the USB connector interface for use. The connection between the connecting block and the guide rod guides the movement of the slider. The movement of the slider causes the USB connector to push against a dustproof baffle, and a damping torsion spring deforms accordingly to expose the interface. Furthermore, through the connection between the damping torsion spring and the dustproof baffle, when the USB connector is not in use, the slider returns to its original position, causing the damping torsion spring to press the dustproof baffle against the surface of the USB connector interface, thus achieving dust protection for the USB connector interface.

[0003] USB interface devices typically integrate fixed LED indicator lights to show the power connection status. LED indicator lights are indicator lights that use light-emitting diodes as light sources. They are semiconductor solid-state light-emitting devices that emit light directly through solid semiconductor chips. They have the characteristics of high efficiency, low power consumption, long durability and environmental friendliness. However, when using existing USB interface devices, their interface ends lack a dustproof structure. When not in use, dust and other dirt can easily enter the interface end, affecting the effect of subsequent wiring. Utility Model Content

[0004] The purpose of this utility model is to provide a USB interface device to solve the problem mentioned in the background art that when the USB interface device is used, its interface end lacks a dustproof structure, and when not in use, dust and other dirt can easily enter the interface end, affecting the effect of subsequent wiring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a USB interface device, comprising:

[0006] The housing includes a USB connector, the surface of which is provided with data lines;

[0007] The protective mechanism includes a slider that acts on the surface of a USB connector. A connecting block is fixedly connected to the surface of the slider. A movable groove is formed on the surface of the USB connector. A guide rod is fixedly connected to the surface of the movable groove. A fixed shaft is fixedly connected inside the slider. A damping torsion spring is wound around the surface of the fixed shaft. A dustproof baffle is rotatably connected to the surface of the fixed shaft.

[0008] Preferably, the movable slots are evenly distributed in four groups on the surface of the USB connector, and the connecting blocks are evenly distributed in four groups on the surface of the slider.

[0009] Preferably, the slider is movably connected to the surface of the connecting block and the guide rod, and the slider is movably connected to the surface of the USB connector via the movable slot.

[0010] Preferably, the fixed shafts are symmetrically distributed in two sets inside the slider, and the dustproof baffle is rotatably connected to the slider through the fixed shafts.

[0011] Preferably, the two ends of the damping torsion spring are fixedly connected to the surface of the fixed shaft and the inside of the dustproof baffle, and the dustproof baffle is connected to the surface of the USB connector by the damping torsion spring.

[0012] Preferably, the cable management mechanism includes an adjusting block that acts on the surface of the data cable. A worm gear is fixedly connected inside the adjusting block, and an adjusting handle is fixedly connected to the surface of the worm gear. An elastic band is sleeved on the surface of the data cable, and an adjusting groove is formed on the surface of the elastic band. A limit block is fixedly connected to the surface of the elastic band.

[0013] Preferably, the two ends of the elastic band are fixedly connected to the surfaces of the adjusting block and the limiting block, and the adjusting grooves are evenly distributed on the surface of the elastic band.

[0014] Preferably, the worm gear is internally rotatably connected to the adjusting handle and the adjusting block, the elastic band is engaged with the surface of the worm gear through the adjusting groove, and the elastic band is movably connected with the surface of the worm gear and the adjusting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By connecting the USB connector and the slider, the movable slider exposes the USB connector interface for use. Then, the connection between the connecting block and the guide rod, and the connection between the connecting block and the movable slot, guides the movement of the slider. Through the connection between the damping torsion spring and the dustproof baffle, the slider moves so that the USB connector pushes against the dustproof baffle, and the damping torsion spring deforms accordingly to expose the interface. When the USB connector is not in use, the slider is reset, and the damping torsion spring returns to its original shape, causing the dustproof baffle to press against the surface of the USB connector interface, thus achieving dust protection for the USB connector interface.

[0017] 2. By connecting the data cable and the elastic band, the data cable can be managed using the elastic band. Then, by connecting the adjusting block and the worm gear, and the worm gear and the adjusting handle, rotating the adjusting handle drives the worm gear to rotate. Then, by connecting the worm gear and the adjusting groove, and the adjusting block and the elastic band, the elastic band can move on the surface of the adjusting block following the rotation of the worm gear, thereby binding the data cable. By connecting the elastic band and the limiting block, it is prevented that one end of the elastic band will completely leave the surface of the adjusting block, thus achieving the effect of managing the data cable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A USB interface device, comprising:

[0027] The housing includes a USB connector 1, which includes multiple LED indicators and a control unit. Each LED indicator can be controlled independently and can display different colors and flashing patterns. The control unit is connected to a data cable 11 and can receive external signals and control the LED indicators according to the signals. The control unit can be programmed by software or hardware to achieve personalized control of the LED indicators. The USB connector 1 also includes a user interface that allows users to directly set and control the status of the LED indicators. The data cable 11 is provided on the surface of the USB connector 1. The data cable 11 is an existing product and is not a technical protection point of this application. It will not be described in detail here.

[0028] The protective mechanism includes a slider 2, which acts on the surface of the USB connector 1 to connect a dustproof baffle 26. A connecting block 21 is fixedly connected to the surface of the slider 2 to connect a guide rod 23. A movable groove 22 is provided on the surface of the USB connector 1 to connect the guide rod 23. A guide rod 23 is fixedly connected to the surface of the movable groove 22 to guide the movement of the slider 2. A fixed shaft 24 is fixedly connected inside the slider 2 to connect the dustproof baffle 26. A damping torsion spring 25 is wound around the surface of the fixed shaft 24 to drive the dustproof baffle 26 to press against the surface of the USB connector 1. The dustproof baffle 26 is rotatably connected to the surface of the fixed shaft 24 to protect the interface end of the USB connector 1 from dust.

[0029] Furthermore, four sets of movable slots 22 are evenly distributed on the surface of the USB connector 1, and four sets of connecting blocks 21 are evenly distributed on the surface of the slider 2. The four sets of movable slots 22 are connected to four sets of guide rods 23, and the four sets of connecting blocks 21 are connected to four sets of guide rods 23, thereby ensuring the stability of the slider 2 movement.

[0030] Furthermore, the slider 2 is movably connected to the surface of the connecting block 21 and the guide rod 23, and the slider 2 is movably connected to the surface of the USB connector 1 through the movable groove 22. Moving the slider 2 can cause the connecting block 21 to move on the surface of the guide rod 23, thereby opening and closing the slider 2.

[0031] Furthermore, the fixed shafts 24 are symmetrically distributed in two sets inside the slider 2. The dust baffle 26 is rotatably connected to the inside of the slider 2 through the fixed shafts 24. The slider 2 moves away from the interface end of the USB connector 1, which in turn moves the dust baffle 26 away from the interface end of the USB connector 1. As a result, it is pushed aside by the USB connector 1, and the damping torsion spring 25 deforms accordingly, exposing the interface end.

[0032] Furthermore, the two ends of the damping torsion spring 25 are fixedly connected to the surface of the fixed shaft 24 and the inside of the dustproof baffle 26. The dustproof baffle 26 is connected to the surface of the USB connector 1 by the damping torsion spring 25. When the USB connector 1 is not in use, the slider 2 is moved to the interface end of the USB connector 1. At this time, the damping torsion spring 25 returns to its original state and drives the dustproof baffle 26 to press against the surface of the interface end of the USB connector 1 to perform dustproof treatment on the interface end of the USB connector 1.

[0033] Furthermore, the cable management mechanism includes an adjustment block 3, which acts on the surface of the data cable 11. A worm gear 31 is fixedly connected inside the adjustment block 3, and an adjustment handle 32 is fixedly connected to the surface of the worm gear 31. An elastic band 33 is sleeved on the surface of the data cable 11, and an adjustment groove 34 is opened on the surface of the elastic band 33. A limit block 35 is fixedly connected to the surface of the elastic band 33.

[0034] Furthermore, both ends of the elastic band 33 are fixedly connected to the surfaces of the adjusting block 3 and the limiting block 35. One end of the elastic band 33 is fixed to the surface of the adjusting block 3, so that when the worm gear 31 rotates, it will only drive the other end of the elastic band 33 to move. At the same time, the setting of the limiting block 35 prevents the elastic band 33 from leaving the surface of the adjusting block 3. The adjusting groove 34 is evenly opened on the surface of the elastic band 33. The even opening of the adjusting groove 34 can freely control the tightness of the elastic band 33.

[0035] Furthermore, the worm gear 31 is internally rotatably connected to the adjusting handle 32 and the adjusting block 3, and the elastic band 33 is engaged with the surface of the worm gear 31 through the adjusting groove 34. The elastic band 33 is movably connected to the surface of the worm gear 31 and the adjusting block 3. Rotating the adjusting handle 32 can drive the worm gear 31 to rotate, thereby driving one end of the elastic band 33 to move on the surface of the adjusting block 3, thereby controlling the tightness of the elastic band 33 binding the data cable 11.

[0036] Working principle: When using the USB connector 1, move the slider 2 away from the interface end of the USB connector 1, causing the dust cover 26 to move away from the interface end of the USB connector 1, thus being pushed open by the USB connector 1. The damping torsion spring 25 deforms accordingly, exposing the interface end, and then it can be plugged in for use. When the USB connector 1 is not in use, move the slider 2 to the interface end of the USB connector 1. At this time, the damping torsion spring 25 returns to its original shape, causing the dust cover 26 to press against the surface of the interface end of the USB connector 1 to protect the interface end of the USB connector 1 from dust. To prevent the two sets of data cables 11 from loosening, the adjustable handle 32 can be rotated to drive the worm gear 31 to rotate, thereby causing one end of the elastic band 33 to move on the surface of the adjusting block 3, thereby controlling the tightness of the elastic band 33 binding the data cable 11.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
