With the development of electronic information technology, some electronic data will serve as very important electronic evidence in the judicial proceedings. When collecting evidence from storage devices, in order to ensure fairness, it is necessary to prevent some people from editing or tampering with the data in the storage device. When extracting the storage device, a read-only lock will be connected between the storage device and the computer, so that the computer cannot edit the contents of the storage device.

[0003] In the prior art, traditional read-only locks often use multiple interfaces to adapt to different storage devices. However, there are many types of common storage devices, and their interface types are also diverse, such as USB interface, PCIe interface, SATA interface, SD card, etc. Their plug-in and unplugging methods are also different, which is inconvenient to use. In addition, if the storage device is accidentally damaged during the plug-in and unplugging process, data may be damaged, which may lead to serious consequences such as obstruction of justice. Therefore, we propose a read-only lock with an easy-to-plug interface structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , comprising a read-only lock body 1, one side of the read-only lock body 1 is provided with a type-c interface 2 for connecting to a computer, and an integrated interface component is provided on the side of the read-only lock body 1 away from the type-c interface 2, wherein:

[0023] The integrated interface assembly includes an interface panel, a power interface 3 is provided on the interface panel, and an SD card slot 4 and a USB interface 5 are provided on the interface panel. A sink is also provided on the read-only lock body 1, and a drawer 6 is slidably connected in the sink. An opening for making way for the drawer 6 is provided on the interface panel, and a spring buckle 7 is provided on one side of the interface panel close to the drawer 6. A card slot 8 matching the spring buckle 7 is provided on one side of the drawer 6. A slide is provided in the drawer 6, and a SATA connector 9 is provided on the inner wall of one side of the slide. The drawer 6 is also provided with a power cord for powering the solid-state hard disk and a connector corresponding to the power supply interface of the mechanical hard disk. The slide groove is also provided with a groove 10, and the groove 10 is provided with an m.2 interface 11. A round sleeve 12 is fixedly connected in the groove 10, and a compression spring is fixedly connected in the round sleeve 12. The upper end of the compression spring is fixedly connected with a fastener 13, and the lower end of the fastener 13 is slidably connected to the round sleeve 12. The upper end of the drawer 6 is also fixedly connected with a spring sheet 14, and the lower end of the spring sheet 14 is fixedly connected with an anti-slip pad.

[0024] Furthermore, telescopic joints 15 are provided at both ends of the spring sheet 14, and a guide block is provided at one end of the spring sheet 14 close to the interface panel. The spring sheet 14 is used to press the mechanical hard disk with an anti-slip pad when the drawer 6 is returned to the sink groove, so as to avoid poor contact of the SATA interface for data transmission due to vibration of the hard disk during operation, thereby fixing the mechanical hard disk. The telescopic joint 15 is provided to ensure that the spring sheet 14 will not interfere with the drawer 6 being stuck in the sink groove after it is deformed by contact with the inner wall of the sink groove.

[0025] Furthermore, the inner wall of the drawer 6 is also provided with a slide rail, and a hard disk rack 16 is slidably connected in the slide rail. The hard disk rack 16 is made of elastic plastic material, and a connecting shell 17 is detachably connected to the hard disk rack 16. In this design, the hard disk rack 16 is suitable for 2.5-inch hard disks, which are mainly used in portable devices such as laptops. When a 3.5-inch hard disk is placed in the drawer 6, the hard disk rack 16 can be removed, and the connecting shell 17 is used to place an SSD solid-state hard disk that also has a SATA interface.

[0026] Furthermore, the interface panel is also provided with a TF card interface 18 and a high-speed CF card interface 19, wherein the TF card interface 18 is used to insert a TF memory card used on devices such as a driving recorder and a mobile phone, while the high-speed CF card interface 19 is used to support the memory card interface of devices such as a digital camera and a video camera, thereby further expanding the reading range of the read-only lock and reducing the demand for accessories.

[0027] Furthermore, the USB interface 5 is a USB 3.0 interface and is backward compatible with the USB 2.0 protocol.

[0028] Working principle: In this read-only lock body, it is based on Rockchip's RK3568CPU chip, equipped with Ubuntu system, to achieve read-only of SATA, PCIe, USB3.0 interface protocol data, without destroying the MD5 value of the storage medium. The core of the solution is RK3568, which is based on the ARM Cortex-A55 core and is a domestic high-end SoC integrating CPU, NPU, and GPU. The main control chip integrates multiple protocol PHY interfaces, and plays the role of carrying Ubuntu operating system and data processing in the solution. RK809 is a module that integrates system power supply and control, including the control of power-on parameters and power-on timing of each power supply of the system, as well as multiple functions such as system switch control and power-on self-start control. The RAM module of this solution is equipped with 2 DDR4 chips, which can realize fast storage and processing of data; the ROM chip mainly uses EMMC chip, which can support EMMC5.1 protocol to realize the loading of system running code and running system. The more important part of this solution is rich communication interface, including 1 x2 PCIe3.0 interface, 1 SATA3.0 interface, 2 USB3.0 interfaces (HOST and OTG), 2 USB2.0 interfaces, and compatible with SD, SPI protocol FLASH and NAND FLASH interfaces. When matching interface components, the SD card slot 4 and USB interface 5 are the most common devices in the current mobile storage devices, and are plug-and-play storage devices, so corresponding interfaces can be set, and the sink groove is set to match the drawer 6 for connecting the most popular mechanical hard disk on the computer. The slide groove in the drawer 6 just matches the 3.5-inch mechanical hard disk. The user can put this kind of mechanical hard disk into the drawer 6 and directly connect the SATA connector 9 to the mechanical hard disk. It should be noted that when this kind of chassis hard disk is running, its inner wall disk will rotate at high speed, so the mechanical hard disk will vibrate to a certain extent, and setting The spring sheet 14 and the anti-slip pad can fix the hard disk, and the m.2 interface 11 located in the groove 10 is matched with the most popular solid-state hard disk at this stage. Together with the round sleeve 12 and the compression spring, the user can use the fastener 13 to temporarily fix the solid-state hard disk after inserting the solid-state hard disk into the m.2 interface 11 to meet the need of reading data. This design not only has rich interface types, but also has fewer requirements for accessories. It reasonably uses the structure to accommodate storage devices, supports all current mainstream storage devices, has fewer requirements for accessories, effectively guarantees data reading efficiency, and is not easy to cause damage to storage devices when reading data.

[0029] The above description is only a preferred specific implementation manner 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 technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
