DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0018] Example: Figure 1-5 As shown, the utility model provides a physical security locking device for a USB interface, comprising an interface plug-in frame 1, a through slot 11 is provided on one side of the interface plug-in frame 1, two horizontal plates 2 are provided inside the interface plug-in frame 1, a pressing mechanism 3 is provided on the interface plug-in frame 1 and the two horizontal plates 2, and a mounting mechanism 4 is provided on the two horizontal plates 2. When the interface plug-in frame 1 is horizontally inserted into the inner wall of the USB interface of the device, the chip on the inner wall of the USB interface passes through the through slot 11. By setting the mounting mechanism 4, the mounting mechanism 4 can make the interface plug-in frame 1 fixedly installed on the inner wall of the USB interface, so as to realize the physical locking of the USB interface of the device, prohibit the insertion of other USB storage devices, and prevent the random copying of data through the USB interface, and improve the versatility of the security locking device (security locking device and interface plug-in frame 1, horizontal plate 2, pressing mechanism 3 and mounting mechanism 4), so as to facilitate the installation of different devices and the disassembly of the security locking device, and by setting the pressing mechanism 3, the pressing mechanism 3 can improve the stability of the interface plug-in frame 1 after installation;
[0019] The mounting mechanism 4 comprises a limit block 41, eight of which are provided. The limit blocks 41 are triangular in shape. Four uniformly distributed contraction grooves 43 are provided on one side of the two horizontal plates 2. The bottom of one of the limit blocks 41 is in active contact with the inner wall of a contraction groove 43. Two telescopic rods 44 are fixedly installed on the bottom wall of the contraction groove 43. The piston ends of two adjacent telescopic rods 44 are fixedly connected to the bottom of a limit block 41. The outer wall of the telescopic rod 44 is movably sleeved with a telescopic spring 45. One end of two adjacent telescopic springs 45 is fixedly connected to the bottom wall of a contraction groove 43. The other ends of two adjacent telescopic springs 45 are fixedly connected to the bottom of a limit block 41. By setting a triangular limit block 41, when the top of the limit block 41 contacts the top wall and the bottom wall of the USB interface, the interface plug-in frame 1 can be fixed to the inner wall of the USB interface. By setting a contraction groove 43, a telescopic rod 44 and a telescopic spring 45, the telescopic rod 44 and the telescopic spring 45 can provide the limit block 41 with a space for upward and downward movement. At the same time, the extension of the telescopic rod 44 and the telescopic spring 45 makes the top of the limit block 41 always contact the top wall or the bottom wall of the USB interface.
[0020] The top and bottom walls of the slot 11 are fixedly mounted with protective pads 12, and two notches 13 are provided on the side of the interface frame 1 away from the slot 11. By providing the protective pads 12, when the chip in the USB interface passes through the inner wall of the slot 11, the protective pads 12 contact the chip to prevent the chip from being worn.
[0021] An anti-slip sleeve 42 is fixedly mounted on the outer wall of the limiting block 41 . By providing the anti-slip sleeve 42 , the anti-slip sleeve 42 can improve the stability between the limiting block 41 and the top wall or bottom wall of the USB interface.
[0022] Two guide grooves 46 are provided on the side wall of the contraction groove 43, and a guide block 47 is slidably installed at one end of the guide groove 46, wherein the opposite sides of two adjacent guide blocks 47 are fixedly connected to the bottom of a limit block 41. By setting the guide grooves 46 and the guide blocks 47, the guide blocks 47 can slide in the vertical direction in the guide grooves 46, thereby guiding the limit block 41 in the vertical direction, so that the limit block 41 can maintain the vertical lifting.
[0023] The clamping mechanism 3 includes a rotating shaft 31, and four rotating shafts 31 are provided. One end of the rotating shaft 31 is rotatably connected to the interface plug-in frame 1, wherein the other ends of two adjacent rotating shafts 31 are fixedly connected to one end of a horizontal plate 2. A torsion spring 32 is movably sleeved on the outer wall of the rotating shaft 31, and one end of the torsion spring 32 is fixedly connected to the side wall of the interface plug-in frame 1, wherein the other ends of two adjacent torsion springs 32 are fixedly connected to one end of a horizontal plate 2. By providing the rotating shaft 31 and the torsion spring 32, the horizontal plate 2 can be flipped and rotated with the axis of the rotating shaft 31 as the center of the circle, and the torsion spring 32 can restore the horizontal plate 2 to a horizontal state after flipping and rotation.
[0024] The pressing mechanism 3 also includes a hand-operated plate 33 , and four hand-operated plates 33 are provided, wherein two adjacent hand-operated plates 33 are fixedly mounted at the other end of a horizontal plate 2 . By providing the hand-operated plates 33 , it is convenient for users to flip and rotate the two horizontal plates 2 toward each other.
[0025] Working principle: When the USB interface of the device needs to be locked, the user holds the interface plug-in frame 1 so that the interface plug-in frame 1 corresponds horizontally to the USB interface, and then pushes the interface plug-in frame 1 horizontally, so that the chip in the USB interface passes through the through slot 11, so that the interface plug-in frame 1 completely enters the inner wall of the USB interface;
[0026] In this process, the tops of the eight anti-slip covers 42 are in contact with the top and bottom walls of the USB interface, and the horizontal thrust of the interface plug-in frame 1 causes the eight limit blocks 41 to move into the corresponding contraction grooves 43. At the same time, the multiple telescopic rods 44 and the telescopic springs 45 are in a contracted state. At the same time, the limit blocks 41, through the telescopic rods 44 and the telescopic springs 45, cause the horizontal plate 2 to flip around the axis of the rotating shaft 31, and the corresponding torsion springs 32 are in a power storage state.
[0027] When the interface plug-in frame 1 completely enters the interior of the USB interface, the four torsion springs 32 are reset, and the two horizontal plates 2 are flipped over and reset through the four rotating shafts 31. At the same time, the tops of the eight anti-slip sleeves 42 are pressed against the top and bottom walls of the USB interface. At this time, the interface plug-in frame 1 is fixed inside the USB interface, so that the interface plug-in frame 1 can be conveniently installed in the USB interface of the device, thereby physically locking the USB interface of the device, prohibiting the insertion of other USB storage devices, and preventing data from being copied randomly through the USB interface. At the same time, the versatility of the safety locking device is improved, which is convenient for installation on different devices and disassembly of the safety locking device.
[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
