It connects to a computer via USB, enabling plug-and-play functionality and facilitating data storage and transfer. A wrist-worn USB flash drive is an innovative storage device that combines the functions of a USB flash drive with a wristband. This design not only makes it easy to carry and avoids the risk of the flash drive being lost, but also allows for easy replacement of a damaged flash drive through a locking mechanism.

[0003] Existing technologies, such as CN206249371U, disclose an anti-loss wristband USB flash drive, comprising a USB flash drive cover, a USB flash drive body, a wristband, and a retractable cable. The cover is fixed to the wristband, and the retractable cable is wrapped around the outside of the wristband, with one end fixedly connected to the USB flash drive body and the other end fixedly connected to the USB flash drive cover. When the USB flash drive is not in use, the flash drive body and the USB flash drive cover are connected as a whole by a plug-in connection. The wristband and the USB flash drive cover are connected at both ends in a retractable manner, allowing for adjustment according to the wearer's wrist size. A vibration module is provided on the back of the USB flash drive cover. This utility model combines the functions of a USB flash drive and a wristband, and has the advantages of ingenious structure, convenient use, simple operation, and low cost.

[0004] To address the issue of stable closure of existing wrist-worn USB drives, which are prone to detaching with slight tugging during daily use, causing the USB drive plug to loosen over time and making it difficult for the wristband to close properly, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing wrist-worn USB flash drives detach easily with a slight pull during daily use, leading to loosening of the USB flash drive plug and difficulty in closing the wristband after long-term use. Therefore, this invention proposes a wrist-worn USB flash drive.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wrist-mounted USB flash drive, comprising an elastic wristband, a USB flash drive plug, a groove, and an auxiliary device. The USB flash drive plug is fixedly connected to the surface of the elastic wristband, the groove is formed on the surface of the elastic wristband, the elastic wristband is provided with a rotating hinge and a magnetic groove, the rotating hinge is fixedly connected to the surface of the elastic wristband, the magnetic groove is formed on the surface of the elastic wristband, the surface of the rotating hinge is provided with an auxiliary device, the auxiliary device comprising a connecting block, the connecting block being rotatably connected to the inner wall of the rotating hinge, the surface of the connecting block being fixedly connected with a magnetic block, and the magnetic block being magnetically connected to the inner wall of the magnetic groove.

[0007] Furthermore, the number of magnetic blocks and magnetic slots are both two sets and symmetrically arranged. The surface of the elastic wristband is provided with a locking groove, and the surface of the elastic wristband is fixedly connected with a locking block, which engages with the inner wall of the locking groove.

[0008] Furthermore, the surface of the elastic wristband is fixedly connected with fixing blocks, and the number of fixing blocks is two sets, which are arranged symmetrically.

[0009] Furthermore, the inner wall of the fixing block is provided with limiting grooves, and there are two sets of limiting grooves arranged symmetrically. The inner wall of the fixing block is slidably connected to a slider.

[0010] Furthermore, a limiting block is fixedly connected to the surface of the slider. There are two sets of limiting blocks arranged symmetrically, and the limiting blocks are slidably connected to the inner wall of the limiting groove.

[0011] Furthermore, the surface of the slider is rotatably connected to a rotating shaft, and the surface of the rotating shaft is rotatably connected to a hinge block, which is slidably connected to the inner wall of the fixed block.

[0012] Furthermore, a support rod is fixedly connected to the surface of the hinge block, the support rod is slidably connected to the fixed block, the support rod is fixedly connected to the surface of the elastic wristband, and a protrusion is fixedly connected to the surface of the support rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an auxiliary device, the use of the USB flash drive is more convenient when the elastic wristband is closed and fixed. By rotating the connecting block, the connecting block rotates stably along the axis of the rotating hinge. Then the magnetic block leaves the inner wall of the magnetic groove, thereby pulling the two sides of the elastic wristband, causing the USB flash drive plug to leave the inner wall of the groove, and causing the locking block to leave the inner wall of the locking groove. When the elastic wristbands on both sides are pulled, the support rod is pulled by the hinge block, causing the slider to drive the limiting block to move along the inner wall of the slide groove. Then the support rod completely leaves the inner wall of the fixing block.

[0015] 2. In this utility model, after the support rod leaves the inner wall of the fixing block, one side of the elastic wristband drives the support rod to rotate along the axis of the rotating shaft, so that the USB flash drive plug is exposed, and the USB flash drive plug can then be used. By setting an auxiliary device, it is easy to close and fix the elastic wristband, avoiding the phenomenon that existing wrist-type USB flash drives will detach with a slight pull during daily use, which will cause the USB flash drive plug to loosen after long-term use, making it difficult to close the wristband. This effectively improves the ease of use of the device. Attached Figure Description

The USB flash drive plug 2 is fixedly connected to the surface of the elastic wristband 1, the groove 3 is formed on the surface of the elastic wristband 1, the elastic wristband 1 is provided with a rotating hinge 41 and a magnetic groove 44, the rotating hinge 41 is fixedly connected to the surface of the elastic wristband 1, the magnetic groove 44 is formed on the surface of the elastic wristband 1, and the auxiliary device 4 is provided on the surface of the rotating hinge 41.

[0025] The specific setup and function of auxiliary device 4 will be explained below.

[0026] In this embodiment: the auxiliary device 4 includes a connecting block 42, which is rotatably connected to the inner wall of the rotating hinge 41. A magnetic block 43 is fixedly connected to the surface of the connecting block 42, and the magnetic block 43 is magnetically connected to the inner wall of the magnetic groove 44.

[0027] Specifically, there are two sets of magnetic blocks 43 and magnetic grooves 44, which are arranged symmetrically. The surface of the elastic wristband 1 is provided with a locking groove 45, and a locking block 46 is fixedly connected to the surface of the elastic wristband 1. The locking block 46 is engaged with the inner wall of the locking groove 45.

[0028] Specifically, the surface of the elastic wristband 1 is fixedly connected with a fixing block 47, and there are two sets of fixing blocks 47 arranged symmetrically.

[0029] Specifically, the inner wall of the fixing block 47 is provided with a limiting groove 48, and there are two sets of limiting grooves 48 arranged symmetrically. The inner wall of the fixing block 47 is slidably connected with a slider 49.

[0030] Specifically, a limiting block 410 is fixedly connected to the surface of the slider 49. There are two sets of limiting blocks 410 arranged symmetrically. The limiting blocks 410 are slidably connected to the inner wall of the limiting groove 48.

[0031] Specifically, the surface of the slider 49 is rotatably connected to a rotating shaft 411, and the surface of the rotating shaft 411 is rotatably connected to a hinge block 412. The hinge block 412 is slidably connected to the inner wall of the fixed block 47.

[0032] Specifically, a support rod 413 is fixedly connected to the surface of the hinge block 412, the support rod 413 is slidably connected to the fixed block 47, the support rod 413 is fixedly connected to the surface of the elastic wristband 1, and a protrusion 414 is fixedly connected to the surface of the support rod 413.

[0033] The effects achieved by the above components are as follows: The rotating hinge 41 facilitates stable rotation of the connecting block 42 along its axis; the connection between the magnetic block 43 and the magnetic groove 44 facilitates the connection of the elastic wristband 1 by the connecting block 42, ensuring the USB plug 2 is stably engaged in the groove 3; the connection between the engaging block 46 and the engaging groove 45 ensures proper alignment of the USB plug 2 connection point, preventing misalignment and gaps that could allow water to enter the USB plug 2; and the limiting groove 48 helps prevent… The slider 49 is detached from the inner wall of the fixed block 47. A connection is provided between the limiting block 410 and the limiting groove 48 to facilitate the constraint of the movement trajectory of the slider 49. A rotating shaft 411 and a hinge block 412 are provided to facilitate the support rod 413 to drive the elastic wristband 1 on one side to rotate stably along the axis of the rotating shaft 411, making it easy to use the USB plug 2. The support rod 413 is provided to facilitate the connection of the elastic wristband 1. The two ends of the elastic wristband 1 are easily separated, which may require re-alignment and connection.

[0034] Working principle: By setting up auxiliary device 4, it is easier to use the USB flash drive when closing and fixing the elastic wristband 1. Rotate the connecting block 42 so that the connecting block 42 rotates stably along the axis of the rotating hinge 41. Then the magnetic block 43 leaves the inner wall of the magnetic groove 44, thereby pulling the two sides of the elastic wristband 1, so that the USB flash drive plug 2 leaves the inner wall of the groove 3, and the locking block 46 leaves the inner wall of the locking groove 45. When the elastic wristbands 1 on both sides are pulled, the support rod 413 is pulled by the hinge block 412, so that the slider 49 drives the limiting block 410 to move along the inner wall of the groove. Then the support rod 413 completely leaves the inner wall of the fixing block 47.

[0035] After the support rod 413 leaves the inner wall of the fixing block 47, one side of the elastic wristband 1 drives the support rod 413 to rotate along the axis of the rotating shaft 411, so that the USB plug 2 is exposed, and the USB plug 2 can then be used. By setting the auxiliary device 4, it is easy to close and fix the elastic wristband 1, avoiding the phenomenon that the existing wrist-type USB drives will come off with a slight pull during daily use, which will cause the USB plug 2 to loosen after long-term use, making it difficult to close the wristband. This effectively improves the ease of use of the device.
