Description

Technical Field

[0001] The present invention relates to the technical field of USB plugs, and in particular to an adjustable USB plug. Background Art

[0002] USB (Universal Serial Bus), whose Chinese name is Universal Serial Bus, is an external bus standard and a technical specification for input and output interfaces. It is widely used in information and communication products such as personal computers and mobile devices, and has been extended to other related fields such as photographic equipment, digital TVs (set-top boxes), and game consoles. The USB interface can also achieve dual-machine interconnection through a special USB connection cable, and can expand more interfaces through a Hub. USB has the advantages of fast transmission speed, ease of use, support for hot plugging, flexible connection, and independent power supply. It can connect to almost all external devices such as mice, keyboards, printers, scanners, cameras, chargers, flash drives, MP3 players, mobile phones, digital cameras, mobile hard drives, external optical drives / floppy drives, USB network cards, ADSL Modems, Cable Modems, etc.

[0003] When not in use, some existing USB plugs are usually exposed to the outside, which can easily cause external dust to enter the inside of the USB plug. Dust accumulates inside the USB plug for a long time, which can easily corrode the internal components of the USB plug, causing damage to the USB plug or poor contact, thereby shortening the service life of the USB plug.

[0004] In view of the above problems, an adjustable USB plug is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an adjustable USB plug that can solve the problems of the background art.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an adjustable USB plug, comprising a USB plug shell, a connecting wire being provided on one side of the USB plug shell, a USB connector being provided inside the USB plug shell, a fixed shaft being fixedly mounted on the surface of the USB plug shell, an outer rod being rotatably sleeved on the surface of the fixed shaft, an inner sliding rod being slidably connected to the interior of the outer rod, one end of the inner sliding rod slidingly passing through the outer rod and extending to the outside of the outer rod, a limiting slide being fixedly mounted on one end of the inner sliding rod located inside the outer rod, the limiting slide being slidably connected to the interior of the outer rod, a tension spring being fixedly mounted on the interior of the outer rod, an end of the tension spring close to the limiting slide being fixedly connected to the limiting slide, and a protective cover being fixedly mounted on one side of the inner sliding rod.

[0007] Preferably, a sliding hole is provided on the protective cover, and a sealing plate is slidably connected inside the sliding hole.

[0008] Preferably, a hook is fixedly mounted on the sealing plate.

[0009] Preferably, a limiting slideway is provided inside the protective cover, a limiting slider is slidably connected inside the limiting slideway, and the limiting slider is fixedly connected to the surface of the sealing plate.

[0010] Preferably, a limiting shaft is fixedly installed inside the limiting slide, the surface of the limiting shaft is slidably connected to the inside of the limiting slider, and an elastic spring is movably sleeved on the surface of the limiting shaft. The end of the elastic spring close to the limiting slider is fixedly connected to the limiting slider, and the end of the elastic spring away from the limiting slider is fixedly connected to the inside of the limiting slide.

[0011] Preferably, a first threading hole is opened on the surface of the protective cover, and a push plate is slidably connected to the interior of the first threading hole, and the side of the push plate close to the sealing plate is fixedly connected to the sealing plate.

[0012] Preferably, a second threading hole is provided on the sealing plate.

[0013] Preferably, a slot is provided inside the fixed shaft, a clamping block is slidably connected inside the slot, a return spring is fixedly installed inside the slot, and one end of the return spring close to the clamping block is fixedly connected to the clamping block.

[0014] Preferably, one end of the block is semicircular.

[0015] Preferably, a slot is provided inside the outer rod, and one end of the clamping block is movably clamped inside the slot.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The adjustable USB plug allows the limiting slide plate and the inner slide bar to be reset by the tension of the tension spring, thereby resetting the protective cover and allowing the protective cover to cover the USB connector, thereby sealing the USB connector and facilitating the sealing of the USB connector. This facilitates the protection of the USB connector when not in use, thereby preventing dust from entering the interior of the USB connector, improving the protection of the USB connector, and reducing the probability of damage to the USB connector.

[0018] (2) The adjustable USB plug allows the card block to slide into the interior of the card slot to fix the angle of the outer rod. When the angle of the connecting line is changed, the outer rod and the protective cover are rotated to bend the connecting line, thereby facilitating the bending of the connecting line. This prevents the user from bending the connecting line back and forth during use, thereby preventing the connecting line from breaking. This improves the convenience of adjusting the angle of the connecting line and facilitates the user's operation.

[0019] (3) When the hook of the adjustable USB plug hooks one end of the connecting wire, the second wire hole will no longer overlap with the first wire hole, and the sealing plate will cover the first wire hole. When the connecting wire is used, the hook will no longer hook the connecting wire, and the sealing plate will slide downward, so that the second wire hole overlaps with the first wire hole, and the second wire hole and the first wire hole are opened, so as to facilitate the sealing of the first wire hole, thereby preventing dust from entering the interior of the USB connector. Dust enters the interior of the USB connector from the interior of the first wire hole, thereby improving the protection of the USB connector.

[0020] (4) The adjustable USB plug allows the hook to hook the other end of the connecting line, and then the hook is no longer pulled, so that the hook and the sealing plate squeeze the other end of the connecting line through the elastic force of the elastic spring, thereby facilitating the fixing of the other end of the connecting line, preventing the connecting line from automatically loosening after being wound, improving the convenience of arranging the connecting line, preventing the loosening phenomenon, facilitating the carrying of the connecting line, and improving the convenience of carrying.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0031] See also Figure 1-6 The present invention provides a technical solution: an adjustable USB plug, comprising a USB plug shell 1, a connecting line 2 is provided on one side of the USB plug shell 1, a USB connector 6 is provided inside the USB plug shell 1, a fixed shaft 9 is fixedly installed on the surface of the USB plug shell 1, an outer rod 8 is rotatably sleeved on the surface of the fixed shaft 9, an inner sliding rod 7 is slidably connected to the inside of the outer rod 8, one end of the inner sliding rod 7 slides through the outer rod 8 and extends to the outside of the outer rod 8, a limiting slide 17 is fixedly installed on one end of the inner sliding rod 7 located inside the outer rod 8, the limiting slide 17 is slidably connected inside the outer rod 8, a tension spring 18 is fixedly installed inside the outer rod 8, and one end of the tension spring 18 close to the limiting slide 17 is fixedly connected to the limiting slide 17, and a protective cover 3 is fixedly installed on one side of the inner sliding rod 7.

[0032] When the USB connector 6 is in the closed position, the protective cover 3 is pulled back, and the inner sliding rod 7 is moved to slide inside the outer rod 8, thereby causing the inner sliding rod 7 to drive the limiting slide 17 to slide inside the outer rod 8 and stretching the tension spring 18, thereby causing the protective cover 3 to no longer cover the USB connector 6, and then causing the protective cover 3 to drive the inner sliding rod 7 and the outer rod 8 to flip around the fixed axis 9, thereby causing the protective cover 3 to no longer seal the USB connector 6. When the USB connector 6 needs to be sealed, the protective cover 3 is pulled, causing the protective cover 3 to drive the inner sliding rod 7 to move, stretching the tension spring 18, and then the protective cover 3 is no longer pulled, so that the limiting slide 17 and the inner sliding rod 7 are reset by the tension of the tension spring 18, thereby restoring the protective cover 3, so that the protective cover 3 covers the USB connector 6, achieving the sealing of the USB connector 6, facilitating the sealing of the USB connector 6, and facilitating the protection of the USB connector 6 when not in use, thereby preventing dust from entering the interior of the USB connector 6, improving the protection of the USB connector 6, and reducing the probability of damage to the USB connector 6.

[0033] By setting the limiting slide 17, it is convenient to restrict the inner sliding rod 7, so that the inner sliding rod 7 can only slide inside the outer rod 8 and cannot slide out of the outer rod 8, thereby minimizing the probability of the inner sliding rod 7 sliding out of the outer rod 8 and improving the stability of the device.

[0034] The protective cover 3 is provided with a sliding hole 23, and the sliding hole 23 is internally slidably connected to the sealing plate 11, and the sealing plate 11 is fixedly installed with a hook 10. The protective cover 3 is provided with a limiting slide 13 inside, and the limiting slide 13 is internally slidably connected to the limiting slider 14, and the limiting slider 14 is fixedly connected to the surface of the sealing plate 11. The limiting slide 13 is internally fixedly installed with a limiting shaft 15, and the surface of the limiting shaft 15 is slidably connected to the internal limiting slider 14. The surface of the limiting shaft 15 is movably sleeved with an elastic spring 16, and one end of the elastic spring 16 close to the limiting slider 14 is fixedly connected to the limiting slider 14, and the end of the elastic spring 16 away from the limiting slider 14 is fixedly connected to the interior of the limiting slide 13. A first threading hole 4 is provided on the surface of the protective cover 3, and a push plate 5 is internally slidably connected to the first threading hole 4. The push plate 5 is fixedly connected to the sealing plate 11 on one side close to the sealing plate 11, and a second threading hole 12 is provided on the sealing plate 11.

[0035] The push plate 5 is pushed, and the push plate 5 slides inside the first threading hole 4, and the sealing plate 11 slides inside the protective cover 3, so that the hook 10 moves to the outside of the protective cover 3, and at the same time, the limiting slider 14 slides inside the limiting slide 13 and on the surface of the limiting shaft 15, so that the limiting slider 14 squeezes the elastic spring 16, and then when the hook 10 moves to the outside of the protective cover 3, the connecting line 2 is wound together, so that the hook 10 hooks the other end of the connecting line 2, and then the hook 10 is no longer pulled, so that the hook 10 and the sealing plate 11 squeeze the other end of the connecting line 2 through the elastic force of the elastic spring 16, so as to facilitate the fixing of the other end of the connecting line 2, preventing the connecting line 2 from automatically loosening after being wound, improving the convenience of arranging the connecting line 2, preventing the loose phenomenon, facilitating the carrying of the connecting line 2, and improving the convenience of carrying.

[0036] When there is no need to fix one end of the connecting wire 2, the connecting wire 2 is taken out from the opening of the hook 10, and then the sealing plate 11 and the hook 10 are reset by the elastic force of the elastic spring 16, and then the sealing plate 11 slides into the interior of the sliding hole 23, thereby hiding the hook 10, making it easier to hide the hook 10, thereby preventing interference with the user's use during use and improving the convenience of using the device.

[0037] When the hook 10 hooks one end of the connecting wire 2, the second wire hole 12 will no longer overlap with the first wire hole 4, and the sealing plate 11 will block the first wire hole 4. When the connecting wire 2 is used, the hook 10 will no longer hook the connecting wire 2, and the sealing plate 11 will slide downward, so that the second wire hole 12 overlaps with the first wire hole 4, and the second wire hole 12 and the first wire hole 4 are opened, so as to facilitate the sealing of the first wire hole 4, thereby preventing dust from entering the interior of the USB connector 6. Dust enters the interior of the USB connector 6 from the inside of the first wire hole 4, thereby improving the protection of the USB connector 6.

[0038] By setting the limiting slider 14 and the limiting shaft 15, the sealing plate 11 is easily restricted, thereby preventing the sealing plate 11 from sliding out of the sliding hole 23, improving the restriction effect on the sealing plate 11, and avoiding damage to the device.

[0039] A slot 20 is provided inside the fixed shaft 9, and a block 22 is slidably connected to the inside of the slot 20. One end of the block 22 is semicircular, and a return spring 21 is fixedly installed inside the slot 20. The end of the return spring 21 close to the block 22 is fixedly connected to the block 22. A slot 19 is provided inside the outer rod 8, and one end of the block 22 is movably engaged inside the slot 19.

[0040] When the charging cable 2 needs to be bent, the protective cover 3 is removed from the USB connector 6, and the protective cover 3, the inner slide bar 7 and the outer rod 8 are turned 180 degrees around the fixed axis 9, so that one end of the connecting cable 2 passes through the first threading hole 4 and the second threading hole 12. When the outer rod 8 rotates on the fixed axis 9, the card block 22 slides inside the card slot 19, and then squeezes the card block 22 into the inside of the slot 20, so that the card block 22 squeezes the reset spring 21, and then when the card block 22 coincides with another card slot 19, , the block 22 is reset by the elastic force of the reset spring 21, and then the block 22 slides into the inside of the card slot 19, thereby fixing the angle of the outer rod 8. When the angle of the connecting line 2 is changed, the outer rod 8 and the protective cover 3 are rotated, thereby bending the connecting line 2, making it easier to bend the connecting line 2, thereby preventing the user from bending the connecting line 2 back and forth during use to the greatest extent, causing the connecting line 2 to break, improving the convenience of adjusting the angle of the connecting line 2, and assisting the user in operation.

[0041] Working principle:

[0042] Pull the protective cover 3, so that the inner slide bar 7 slides inside the outer rod 8, and the inner slide bar 7 drives the limiting slide plate 17 to slide inside the outer rod 8, and stretches the tension spring 18, so that the protective cover 3 is no longer covering the USB connector 6, and then the protective cover 3 drives the inner slide bar 7 and the outer rod 8 to flip around the fixed axis 9, so that the protective cover 3 no longer seals the USB connector 6. When it is necessary to seal the USB connector 6, pull the protective cover 3, so that the protective cover 3 drives the inner slide bar 7 to move, stretch the tension spring 18, and then stop pulling the protective cover 3, so that the limiting slide plate 17 and the inner slide bar 7 are reset by the tension of the tension spring 18, and then the protective cover 3 is reset, so that the protective cover 3 covers the USB connector 6, and the USB connector 6 is sealed. Push the push plate 5, so that the push plate 5 slides inside the first threading hole 4, and then the sealing plate 11 slides inside the protective cover 3, so that the hook 10 moves to the outside of the protective cover 3, and at the same time, the limiting slider 14 slides inside the limiting slide 13 and on the surface of the limiting shaft 15, so that the limiting slider 14 squeezes the elastic spring 16, and then when the hook 10 moves to the outside of the protective cover 3, the connecting line 2 is wound together, so that the hook 10 hooks the other end of the connecting line 2, and then the hook 10 is no longer pulled, so that the hook 10 and the sealing plate 11 squeeze the other end of the connecting line 2 through the elastic force of the elastic spring 16, so as to facilitate the fixation of the other end of the connecting line 2 to prevent the connecting line 2 from automatically loosening after being wound.

[0043] When the hook 10 hooks one end of the connecting line 2, the second threading hole 12 will no longer overlap with the first threading hole 4, and the sealing plate 11 will block the first threading hole 4. When the connecting line 2 is used, the hook 10 will no longer hook the connecting line 2, and the sealing plate 11 will slide downward, so that the second threading hole 12 overlaps with the first threading hole 4, and the second threading hole 12 and the first threading hole 4 are opened, so as to facilitate sealing the first threading hole 4.

[0044] Remove the protective cover 3 from the USB connector 6, and flip the protective cover 3, the inner slide rod 7 and the outer rod 8 one hundred and eighty degrees around the fixed axis 9, so that one end of the connecting line 2 passes through the inside of the first threading hole 4 and the second threading hole 12. When the outer rod 8 rotates on the fixed axis 9, the card block 22 will slide inside the card slot 19, and then squeeze the card block 22 into the inside of the slot 20, so that the card block 22 squeezes the reset spring 21, and then when the card block 22 coincides with another card slot 19, the card block 22 will be reset by the elastic force of the reset spring 21, and then the card block 22 will slide into the inside of the card slot 19, thereby fixing the angle of the outer rod 8. When the angle of the connecting line 2 is changed, the outer rod 8 and the protective cover 3 are rotated, so that the connecting line 2 is bent, which facilitates the bending of the connecting line 2.
