Description

Technical Field

[0001] The utility model relates to the technical field of U disk technology, in particular to a dustproof U disk. Background Art

[0002] U disk is the abbreviation of USB (USB flash disk), which is also called "U disk" according to its homophony. U disk is a kind of flash memory, so it is sometimes called a flash disk. The biggest difference between U disk and hard disk is that it does not require a physical drive, plug and play, and its storage capacity is far greater than that of floppy disk, making it very easy to carry.

[0003] When the existing USB flash drives are not in use, the metal plugs of the USB flash drives are mostly exposed, which makes it easy for dust to enter the USB flash drives from the plug cavity and adhere to the inner wall of the plug. As the dust increases, the reading and writing efficiency of the USB flash drives will be affected, which is not conducive to the efficient use of the USB flash drives. Utility Model Content

[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0022] like Figure 1-Figure 5As shown, a dustproof U disk provided in this embodiment includes a dustproof box 1, a pull-out rod 4 is slidably connected to the inner wall of the dustproof box 1, one end of the pull-out rod 4 is hooked and connected to a limiting pull rope 12, an ejection spring 13 is fixed to one end of the inner wall of the dustproof box 1, and a U disk body 3 is rotatably connected between the inner walls of the pull-out rod 4 through a rotating shaft 14, a locking hole 6 is opened at the top of the dustproof box 1, a lower pressing groove 10 is opened at the bottom of the inner wall of the locking hole 6, and a pressure plate 7 is slidably connected in the lower pressing groove 10.

[0023] One end of the limiting pull rope 12 is fixedly connected to the inner wall of the dustproof box 1. The length of the limiting pull rope 12 is less than the length of the groove on the inner wall of the dustproof box 1. The limiting pull rope 12 limits the pop-up pull rod 4 to the inner wall of the dustproof box 1 to prevent it from falling out. The traditional cap-type dustproof structure requires the U disk to be separated from the cap, which easily causes the cap to be lost. The present device solves this drawback.

[0024] A pressure plate 7 is slidably connected to the top of the dustproof box 1, and a pressure column 8 is glued and fixed to the bottom of the pressure plate 7. The bottom of the pressure column 8 is welded and fixed to the pressure plate 7. The pressure plate 7 is flush with the bottom of the inner wall of the locking hole 6. When the locking block 15 enters the locking hole 6, the arc-shaped pressure plate 7 is squeezed to the bottom. When the locking groove 16 is located at the top of the arc-shaped pressure plate 7, the arc-shaped pressure plate 7 pops out and is inserted into the locking groove 16 to achieve a locking effect.

[0025] An arc-shaped baffle rod 9 is formed on the top of the pressure plate 7 , and the arc-shaped baffle rod 9 is located between the pressure columns 8 . A limit spring 11 is clamped at the bottom of the pressure plate 7 , and the limit spring 11 is fixedly connected to the inner wall of the lower pressure groove 10 .

[0026] A blocking cover 5 is fixed to one end of the outer portion of the pull rod 4 by screws, a locking block 15 is glued to one side of the outer wall of the blocking cover 5 , and a locking groove 16 is provided at the bottom of the locking block 15 .

[0027] The locking groove 16 and the arc-shaped blocking rod 9 are movably mounted.

[0028] The working principle of this device: when this device is in use, the initial position of the blocking cover 5 is in close contact with the outer wall of the dustproof box 1, and the locking groove 16 at the bottom of the locking block 15 is clamped with the arc-shaped blocking rod 9 in the locking hole 6 to lock the pull-out rod 4. This method can keep the U disk body 3 inside the dustproof box 1 to prevent the metal plug from being exposed to dust for a long time when the U disk is not in use, thereby affecting the reading and writing efficiency of the plug and the internal circuit. When the U disk is in use, the pressing key 2 can be pressed down, and the pressing key 2 is connected to the pressing column 8. The pressing column 8 can press down the pressing plate 7. The pressing plate 7 carries the arc-shaped blocking rod 9 into the pressing groove 10 and squeezes the limit spring 11. The arc-shaped blocking rod 9 slides out of the locking groove 16, and the ejection spring 13 pushes the pull-out rod 4 out of the dustproof box 1, and the U disk body 3 leaks out. The USB end or TYPE-C end of the U disk can be used by rotating the U disk body 3 through the rotating shaft 14.

[0029] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
