Description

Technical Field

[0001] The utility model relates to the field of U disk related products, in particular to a safety protection device for a U disk. Background Technique

[0002] The U disk is short for USB disk, and is also called "you disk" according to the homophone. The U disk is a kind of flash memory, so it is sometimes also called a flash drive. The biggest difference between the U disk and the hard disk is that it does not require a physical drive, is plug and play, and its storage capacity far exceeds that of the floppy disk, making it extremely convenient to carry. And the interface, as one of the important components of the U disk, is the main component for data transmission.

[0003] However, it still has the following disadvantages in actual use:

[0004] For the external protection treatment of the existing U disk transmission interface, a protective cover is generally added, and a socket connection method is used for its own stability. However, this socket connection method lacks a positioning component, and the protective cover is easily loosened, reducing the protection effect on the interface, and has defects. Content of the Utility Model

[0005] The purpose of the utility model is to provide a safety protection device for a U disk to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a safety protection device for a U disk, including a U disk body, one end of the U disk body is fixedly connected with a data interface, and support plates are fixedly connected to the outer walls on both sides of the U disk body. A chute is provided on one side of the support plate, a slide bar is fixedly connected in the chute, a slider is slidably sleeved on the slide bar, one end of the slider is rotatably connected with a rotating shaft, and one end of the rotating shaft is fixedly connected with a swing plate. An end cover is provided between one ends of the two swing plates. Both sides of the end cover are fixedly connected with the swing plates through connecting blocks. A cross plate is fixedly connected between the two sliders. A stop rod is slidably inserted into the cross plate. One end of the stop rod is fixedly connected with a holding block, and the other end of the stop rod is fixedly connected with a limiting block. An elastic mechanism is sleeved on the stop rod, and both ends of the elastic mechanism are fixedly connected with the limiting block and the cross plate respectively. A positioning plate is fixedly connected to one side of the U disk body, and two stop grooves corresponding to the stop rod are provided on the positioning plate.

[0007] Preferably, the stop rod is slidably inserted in the middle of the cross plate.

[0008] Preferably, the elastic mechanism is a spring.

[0009] Preferably, a plurality of anti-slip lines are provided on the outer side wall of the holding block and are inclined.

[0010] Preferably, both ends of the cross plate are bent downward.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For the safety protection device of the USB flash drive, by pulling the holding block, the stop rod is disengaged from the stop groove on the positioning plate. At this time, the limiting block will squeeze the elastic mechanism. Subsequently, when pulling the end cover, the connecting block can be used to promote the movement of the swing plate. The swing plate pulls the slider to slide on the sliding rod through the rotating shaft. When the swing plate is flipped and the end cover is displaced to one end of the data interface, press the end cover to be clamped on the data interface. Then release the holding block. At this time, the elastic mechanism in the compressed state will cause the stop rod to rebound into another stop groove under the action of its own resilience to achieve fixation. The present utility model realizes the positioning of the end cover through the setting of the clamping and fixing component, avoids the loosening of the end cover, and it is not easy to lose during the assembly connection between the end cover and the USB flash drive body.

[0019] Please refer to Figure 1-2 , an embodiment provided by the present utility model: a security protection device for a USB flash drive, including a USB flash drive body 1. One end of the USB flash drive body 1 is fixedly connected with a data interface 2. Support plates 3 are fixedly connected to the outer walls on both sides of the USB flash drive body 1. A chute is provided on one side of the support plate 3, and a slide bar 4 is fixedly connected in the chute. A slider 5 is slidably sleeved on the slide bar 4. One end of the slider 5 is rotatably connected with a rotating shaft 6. One end of the rotating shaft 6 is fixedly connected with a swing plate 7. An end cover 8 is provided between one ends of the two swing plates 7. Both sides of the end cover 8 are fixedly connected with the swing plate 7 through connecting blocks 16. A cross plate 9 is fixedly connected between the two sliders 5. A stop rod 10 is slidably inserted into the cross plate 9. One end of the stop rod 10 is fixedly connected with a holding block 11. The other end of the stop rod 10 is fixedly connected with a limiting block 12. An elastic mechanism 13 is sleeved on the stop rod 10. Both ends of the elastic mechanism 13 are fixedly connected with the limiting block 12 and the cross plate 9 respectively. A positioning plate 14 is fixedly connected to one side of the USB flash drive body 1. Two stop grooves 15 corresponding to the stop rod 10 are provided on the positioning plate 14. Specifically, pulling the holding block 11 drives the stop rod 10 to loosen from the stop groove 15 on the positioning plate 14. At this time, the limiting block 12 will squeeze the elastic mechanism 13. Then, pulling the end cover 8 can cause the swing plate 7 to move by using the connecting block 16. The swing plate 7 pulls the slider 5 to slide on the slide bar 4 through the rotating shaft 6. When the swing plate 7 is flipped and the end cover 8 is displaced to one end of the data interface 2, pressing the end cover 8 to be clamped on the data interface 2. Then, releasing the holding block 11. At this time, the elastic mechanism 13 in a compressed state rebounds the stop rod 10 into another stop groove 15 under the action of its own resilience force to achieve fixation.

[0020] In this embodiment, the stop rod 10 is slidably inserted in the middle of the cross plate; the elastic mechanism 13 is a spring, with high elasticity; a plurality of anti-slip lines are provided on the outer side wall of the holding block 11 and are inclined, increasing the friction when holding; both ends of the cross plate 9 are bent downward, reserving space for the stop rod 10.

[0021] Working principle: First, pull the holding block 11 to drive the stop rod 10 to disengage from the stop groove 15 on the positioning plate 14. At this time, the limit block 12 will squeeze the elastic mechanism 13. Subsequently, pull the end cover 8, and the swing plate 7 can be driven by the connecting block 16. The swing plate 7 pulls the slider 5 to slide on the slide rod 4 through the rotating shaft 6. Flip the swing plate 7 to make the end cover 8 displace to one end of the data interface 2, then press the end cover 8 to be clamped on the data interface 2. Subsequently, release the holding block 11. At this time, the elastic mechanism 13 in the compressed state will cause the stop rod 10 to rebound into another stop groove 15 under the action of its own resilience to achieve fixation.
