[0043] Please also read Figures 1 to 3 The utility model proposes a network port security lock, which can be used on a device with a network port 800. The device can be a switch, a router, or a computer, and no specific limitation is made here.

[0044] The network port safety lock includes a locking member 100 and an unlocking lock assembly 200. The locking member 100 can be made of many materials, such as metal, harder plastic, or other materials, which are not specifically limited here. There are many installation positions for the locking member 100, for example, the locking member 100 is directly and movably installed on the device; for another example, the locking member 100 is movably installed on the connecting member and installed on the device through the connecting member, which are not listed here one by one.

[0045] The locking member 100 has a first locking position, a second locking position and an unlocking position. When the locking member 100 is in the first locking position, the locking member 100 limits the crystal head 900 located in the network port 800 so that the crystal head 900 cannot be pulled out of the network port 800; when the locking member 100 is in the second locking position, the locking member 100 blocks the network port 800 so that the crystal head 900 located outside the network port 800 cannot be inserted into the network port 800; when the locking member 100 is in the unlocking position, the locking member 100 unlocks the limit on the crystal head 900 or exposes the network port 800 so that the crystal head 900 can be pulled out or inserted into the network port 800.

[0046] It should be noted that there are many ways for the locking member 100 to limit and release the position of the crystal head 900 in the network port 800. For example, the network port 800 itself has a limiting effect on the crystal head 900, and the crystal head 900 can be removed from the network port 800 by pressing the unlocking portion 910 of the crystal head 900. When the locking member 100 is in the first locking position, the locking member 100 blocks the unlocking portion 910 of the crystal head 900, thereby achieving the limiting effect, thereby making the crystal head 900 cannot be pulled out from the network port 800. When the locking member 100 is in the unlocked position, the locking member 100 presses the unlocking portion 910 of the crystal head 900 in the unlocked position, thereby achieving the effect of releasing the limit of the crystal head 900, or the locking member 100 exposes the unlocking portion 910 of the crystal head 900 when it is in the unlocked position, so that the user can pull the crystal head 900 out from the network port 800 by pressing the unlocking portion 910 of the crystal head 900, thereby achieving the effect of releasing the limit of the crystal head 900.

[0047] For another example, the locking member 100 is provided with an abutment portion protruding in the direction of the crystal head 900. When the locking member 100 is in the first locking position, the abutment portion abuts against the end of the crystal head 900 away from the network port 800, thereby achieving a limiting effect, and making it impossible for the crystal head 900 to be pulled out of the network port 800. When the locking member 100 is in the unlocking position, the abutment portion is arranged away from the crystal head 900, so that the crystal head 900 is not affected by the abutment portion and can move in the direction away from the network port 800, thereby achieving the effect of releasing the limiting of the crystal head 900. These are not listed one by one here.

[0048] The unlocking lock assembly 200 is used to limit the locking member 100 at the first locking position or the second locking position. The unlocking lock assembly 200 can also limit the locking member 100 at the unlocking position, thereby achieving the function of opening the network port 800, which is not limited here.

[0049] There are many ways for the unlocking lock component 200 to limit and release the limit of the locking member 100. For example, two limit holes are set on the locking member 100, and the unlocking lock component 200 limits the locking member 100 located at the first locking position or the second locking position by plugging and cooperating with different limit holes. The unlocking lock component 200 releases the plugging and cooperating with the corresponding limit hole by extending out of the corresponding limit hole, thereby releasing the limit on the locking member 100. For another example, the unlocking lock component 200 limits the locking member 100 by clamping it at the first locking position or the second locking position, and the unlocking lock component 200 releases the limit on the locking member 100 by loosening the clamping of the locking member 100. These methods are not listed here one by one.

[0050] When the network port safety lock is used to lock the network port 800 in use on the device, the unlocking lock assembly 200 is first operated to unlock the limit of the locking member 100, then the locking member 100 is switched to the unlocked position, the crystal head 900 is then inserted into the network port 800, the locking member 100 is then switched to the first locked position, and finally the unlocking lock assembly 200 is operated to limit the locking member 100. When the network port safety lock is used to lock the idle mesh on the device, the unlocking lock assembly 200 is first operated to release the limit of the locking member 100, then the locking member 100 is switched to the unlocked position, the crystal head 900 is then pulled out of the network port 800, the locking member 100 is then switched to the second locked position, and finally the unlocking lock assembly 200 is operated to limit the locking member 100.

[0051] The technical solution of the utility model controls the used network ports and idle network ports by adopting a network port safety lock, and the network port safety lock includes a locking member 100 and an unlocking lock assembly 200, and the locking member 100 has a first locking position, a second locking position and an unlocking position; when the locking member 100 is in the first locking position, the locking member 100 limits the position of the crystal head 900 in the network port 800, so that the crystal head 900 cannot be pulled out of the network port 800; the locking member 100 When the locking member 100 is in the second locking position, the locking member 100 blocks the network port 800, so that the crystal head 900 outside the network port 800 cannot be inserted into the network port 800; when the locking member 100 is in the unlocking position, the locking member 100 unlocks the limit of the crystal head 900 or exposes the network port 800, so that the crystal head 900 can be pulled out or inserted into the network port 800; the unlocking lock assembly 200 is used to limit the locking member 100 in the first locking position or the second locking position. In this way, by switching the locking member 100 between the first locking position and the second locking position, the crystal head 900 in the network port 800 can be prevented from being pulled out or the crystal head 900 can be inserted into the network port 800, so that the network port safety lock can control the network port in use and the idle network port, and by switching the locking member 100 to the unlocking position, the crystal head 900 can be pulled out or inserted into the network port 800, so as not to affect the normal use of the network port 800.

[0052] Please also read Figures 1 to 4 In some embodiments of the utility model, the network port safety lock further includes a housing 300, a mounting groove 310 is concavely provided on the surface of the housing 300, the locking member 100 is movably mounted in the mounting groove 310, and the unlocking lock assembly 200 is mounted in the mounting groove 310.

[0053] The shell 300 can be made of many materials, such as metal, hard plastic, or other materials, which are not specifically limited here. The end of the shell 300 facing away from the device can be provided with a mark to facilitate the user to identify the position of the locking member 100, thereby facilitating the user to operate the network port security lock.

[0054] There are many ways for the locking member 100 to move in the installation slot 310. For example, by setting a plurality of buckle positions in the installation slot 310, the position of the locking member 100 can be changed by driving the locking member 100 to buckle at different buckle positions. For another example, the locking member 100 can be a gear rack, and the position of the locking member 100 can be changed by rotating the gear to control the movement of the rack. The following are not listed here. There are many ways for the unlocking lock assembly 200 to be installed in the installation slot 310.

The main control board 700 is used to receive the trigger signal of the micro switch 600 and transmit the trigger signal to the background.

[0069] In this way, when the locking member 100 is located in the second locking position, the locking member 100 triggers the micro switch 600, thereby triggering the switch to send a trigger signal to the main control board 700, and then the main control board 700 sends the trigger signal to the background. At this time, the background can receive the trigger signal and know that the network port 800 is in an idle state. When the locking member 100 is located in the second locking position, the locking member 100 does not trigger the micro switch 600. At this time, the background does not receive the trigger signal sent by the main control board 700, so that the background can know that the network port 800 is in use.

[0070] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
