Description

Technical Field

[0001] This utility model relates to the field of mobile storage device technology, specifically to a USB flash drive structure with a Type-C anti-loss cap. Background Technology

[0002] A USB flash drive, also known as a USB flash drive, is a miniature, high-capacity portable storage device that uses a USB interface and requires no physical drive. It allows for data exchange with computers or other devices via the USB interface. Small in size and easy to carry, it is widely used for storing and transferring personal files, work documents, photos, videos, and other digital content.

[0003] Existing Type-C interface USB flash drives generally adopt a detachable protective cap design or a rotating protective cap design. When using them, the protective cap needs to be removed or the dust cap needs to be unscrewed. However, the detachable protective cap is not physically connected to the USB flash drive body, and frequent plugging and unplugging can easily lead to its loss. The rotating protective cap lacks a limiting structure and cannot securely protect the Type-C interface. It is easy for the USB flash drive to rotate on its own during the movement of the USB flash drive, thus making it difficult to achieve a certain level of protection for the Type-C interface. Utility Model Content

[0004] The purpose of this utility model is to provide a USB flash drive structure with a Type-C anti-loss cap, which integrates the anti-loss cap with the USB flash drive body, solving the problems of easy loss of the anti-loss cap, insufficient interface protection, cumbersome plugging and unplugging operations, and imbalance of the center of gravity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a USB flash drive structure with a Type-C anti-loss cap, comprising a main body, a Type-C interface, and an anti-loss cap body. A rotating shaft is fixed to both the top and bottom of the main body. A limiting cover is fixed to one end of the rotating shaft. A rotating shell is rotatably connected to the surface of the rotating shaft. A torsion spring is fixed to the bottom of the upper limiting cover. The bottom of the torsion spring is fixedly connected to the top of the upper rotating shell. An extension shell is fixed to the surface of the rotating shell. Two limiting protrusions are fixed to both the top and bottom of the anti-loss cap body. Two sliding grooves are formed on the surface of the extension shell. The limiting protrusions are slidably connected to the surfaces of the sliding grooves. Two plug-in plates are fixed to the surface of the anti-loss cap body. Two plug-in slots are formed at both the head and tail of the main body.

[0022] Please see Figures 1-6 A USB flash drive structure with a Type-C anti-loss cap includes a main body 1, a Type-C interface 2, and an anti-loss cap body 8. The main body 1 has a rotating shaft 3 fixed at both the top and bottom. A limit cover 5 is fixed at one end of the rotating shaft 3. A rotating shell 4 is rotatably connected to the surface of the rotating shaft 3. A torsion spring 6 is fixed at the bottom of the upper limit cover 5. The bottom of the torsion spring 6 is fixedly connected to the top of the upper rotating shell 4. An extension shell 7 is fixed to the surface of the rotating shell 4. The anti-loss cap body 8 is slidably connected to the inner wall of the extension shell 7. Two limit protrusions 9 are fixed at both the top and bottom of the anti-loss cap body 8. Two sliding grooves 10 are opened on the surface of the extension shell 7. The limit protrusions 9 are slidably connected to the surface of the sliding grooves 10. Two plug-in plates 11 are fixed to the surface of the anti-loss cap body 8. Two plug-in slots 12 are opened at both the head and tail of the main body 1.

[0023] Type-C interface 2 is used for connection with the device. The design of the rotating shaft 3 allows the rotating shell 4 to rotate on its surface. The torsion spring 6 provides a preload force for the anti-loss cap body 8 to rotate towards the head of the main body 1. This allows the anti-loss cap body 8 to naturally rotate to the head of the main body 1. The anti-loss cap body 8 can slide inside the extension shell 7, and the limiting protrusion 9 also slides on the surface of the slide groove 10. Through the cooperation of the limiting protrusion 9 and the slide groove 10, the anti-loss cap body 8 is prevented from detaching from the extension shell 7. When the USB flash drive is in the head or tail position, the sliding anti-loss cap body 8 can allow the connector plate 11 to enter the connector slot 12, thereby protecting the Type-C interface 2 or limiting the rotation shell 4 and the anti-loss cap body 8. This prevents the torsion spring 6 from automatically rotating the rotating shell 4 to the head position of the main body 1 during data transmission. The above design ensures that the Type-C interface 2 is protected, completely solves the problem of accessory loss, and also prevents the anti-loss cap body 8 from separating from the Type-C interface 2 when the USB flash drive is in motion. It is especially suitable for high-frequency usage scenarios such as mobile office.

[0024] Furthermore, two reinforcing plates 18 are fixed between the upper and lower extended shells 7;

[0025] The design of the reinforcing plate 18 can enhance the structural strength of the upper and lower extension shells 7, thereby improving rigidity and reducing deformation.

[0026] Furthermore, magnets 17 are fixed to both the surface of the plug plate 11 and the inner wall of the plug groove 12;

[0027] After the plug plate 11 is inserted into the plug slot 12 through the anti-loss cap body 8, the magnet 17 on the surface of the plug plate 11 and the magnet 17 inside the plug slot 12 can attract each other, thereby using magnetic force to further limit the anti-loss cap body 8.

[0028] Furthermore, a sealing gasket 15 is fixed on the surface of the anti-loss cap body 8, and sealing grooves 16 that cooperate with the sealing gasket 15 are opened at the head and tail of the main body 1.

[0029] When the anti-loss cap body 8 is attached to the head or tail surface of the main body 1, the sealing gasket 15 will be able to deform under pressure and enter the sealing groove 16, thereby improving the sealing performance after the main body 1 is connected to the anti-loss cap body 8, and further enhancing the protection effect of the Type-C interface 2.

[0030] Furthermore, an arc-shaped groove 13 is provided on the top of the upper rotating shell 4, and a limiting rod 14 is fixed on the top of the main body 1. The limiting rod 14 is slidably connected to the surface of the arc-shaped groove 13.

[0031] When the rotating shell 4 rotates on the surface of the rotating shaft 3, the limiting rod 14 can rotate together on the surface of the arc groove 13, so that the rotating shell 4 can be limited to a 180-degree angle, thereby improving the convenience of use.

[0032] Furthermore, the rotating shaft 3 is made of 316L stainless steel;

[0033] Using 316L stainless steel for the rotating shaft 3 can give it good wear resistance, ensure that there is no serious wear after multiple rotations, and improve the service life of the rotating shaft 3.

[0034] Furthermore, the rotating shell 4, the extension shell 7, and the anti-loss cap body 8 are all made of ABS plastic.

[0035] ABS plastic has good mechanical strength, chemical resistance and relatively low cost, which makes the rotating shell 4, the extension shell 7 and the anti-loss cap body 8 lighter.

[0036] Furthermore, a protruding ring 19 is fixed on the surface of the anti-loss cap body 8;

[0037] The protruding ring 19 allows users to connect it with a lobster clip or other connectors, making the USB flash drive easier to carry.

[0038] Working principle: In use, first overcome the magnetic attraction to slide the anti-loss cap body 8 outward, so that the plug plate 11 can be taken out from the plug slot 12. Then rotate the rotating shell 4 so that the anti-loss cap body 8 can rotate to the tail of the main body 1. Then move the anti-loss cap body 8 again so that the plug plate 11 enters the plug slot 12 at the tail of the main body 1, thereby completing the limiting and turning of the anti-loss cap body 8. At this time, it can be connected to the external device normally through the Type-C interface 2 for data transmission.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
