Description

Technical Field

[0001] The utility model relates to the technical field of U disks, in particular to a portable U disk with a push-pull dust cover. Background Art

[0002] USB disk, referred to as U disk, is a mobile storage device used to back up data and is easy to carry. U disk is a kind of flash memory, so it is also called a flash drive. It is small and easy to carry, has a large storage capacity and is cheap. At present, the common U disks on the market are direct plug-in, push-pull, rotating, capped, etc. From the perspective of dustproof effect, wear and security, the direct plug-in type is the worst, followed by the push-pull and rotating types, and the capped type is more ideal. The direct plug-in interface is exposed to the outside, which is the most prone to wear and the storage security is also poor. Therefore, most U disks on the market have poor dustproof effect and poor wear resistance. After a long time of use, it is easy to cause more dust to enter, and long-term wear will cause the U disk to be damaged and its storage content to be lost. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Embodiment: A portable USB flash drive with a push-pull dust cover comprises a main body 1 and a shell arranged on the main body 1, the shell comprising a lower shell 2 fixedly connected to the outer side of the main body 1 and an upper shell 3 movably connected to the top of the lower shell 2, a dustproof component for blocking dust on the main body 1 is arranged between the upper shell 3 and the lower shell 2, and the dustproof component can be well provided for the interface of the main body 1 of the USB flash drive, and the dust from the outside can be blocked from entering the interior thereof, so that the USB flash drive is not affected, the dustproof component comprises two symmetrical slide grooves 4 provided on the main body 1, spherical bayonet holes 5 are provided at both ends of the slide grooves 4, hollow grooves 6 are provided on both sides of the lower shell 2, the upper shell 3 and the main body 1 are connected by a circular clamping column 7, and a spherical clamping cap 8 is fixedly connected to one end of the circular clamping column 7.

[0027] See attached Figure 1-5 When the upper shell 3 is pulled, the circular card column 7 at the bottom moves upward along the slide groove 4 under the action of the force of the upper shell 3. The outer side of the spherical card cap 8 is provided with an elastic rubber layer. At this time, the spherical card cap 8 at one end of the circular card column 7 is separated from the spherical card slot 5 at one end of the slide groove 4 until it moves into the spherical card slot 5 at the other end of the slide groove 4. A silicone cover cap 9 is fixedly installed in the upper shell 3, and the silicone cover cap 9 is embedded with the interface on the main body 1. During the movement, the silicone cover cap 9 is separated from the external interface on the main body 1. Since the diameter of the spherical card slot 5 is larger than the width of the slide groove 4, the diameter of the spherical card cap 8 is larger than the diameter of the spherical card slot 5, the spherical card cap 8 will be subjected to resistance when it slides into the spherical card slot 5 at the other end of the slide groove 4. The spherical card cap 8 is connected to the spherical card slot 5. At this time, stop pulling the upper shell 3, and then rotate the main body 1 or the upper shell 3 ninety degrees along the hollow groove 6, that is, the spherical card cap 8 rotates in the spherical card slot 5 as shown in FIG. Figure 2 As shown, you can then use this USB flash drive.

[0028] See attached Figure 1-5 As shown in the figure, after use, the main body 1 or the upper shell 3 is rotated in the opposite direction by 90 degrees, and the upper shell 3 is pushed so that the upper shell 3 drives the circular card column 7 to move downward along the slide groove 4 until the spherical card cap 8 at its bottom end is disengaged from the spherical card socket 5 at one end and goes into the spherical card 5 at the other end. At this time, the silicone cover cap 9 in the upper shell 3 is re-engaged with the external interface in the main body 1 to protect it from dust.

[0029] See attached Figure 1-5 As shown in the figure, it also includes a buckle assembly arranged at the bottom of the main body 1 for easy carrying of the U disk. By setting the bayonet assembly, the U disk can be conveniently connected to components such as a key chain, so as to be easy to carry. The buckle assembly includes a limiting groove opened at the bottom of the main body 1, and a pull rod 10 is slidably connected in the limiting groove. The pull rod 10 and the main body 1 are fixedly connected by a spring 11. By pulling the pull rod 10 to move upward, the spring 11 is compressed, and the pull rod 10 moves out of the limiting groove at one end. At this time, components such as a key chain or a key ring can be clamped on the pull rod 10, and then the pull rod 10 is released. Under the reaction force of the spring 11, the pull rod 10 is re-clamped in the limiting groove, which facilitates the carrying of the U disk and avoids the situation where hard components such as key rings are difficult to clamp on the U disk.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
