When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0043] The embodiment of the utility model provides a type-C port locking device. The type-C port locking device is used to connect a type-C port and unlock the type-C port. The type-C port herein is an electrical connection structure.

[0044] like Figures 1 to 8 As shown, the type-C port includes a pin connector 190, and the pin connector 190 includes a limiting protrusion 191. The type-C port locking device includes a lock body 100, a plug 110, a locking member 120, and a locking assembly. The plug 110 is installed on the lock body 100, and the plug 110 has an inserted state that can be inserted into the type-C port and an exit state that exits the type-C port. The locking member 120 is movably arranged in the lock body 100, and the locking member 120 has an unlocked state and a locked state. In the locked state, the locking member 120 and the limiting protrusion 191 are limitedly matched to stop the plug 110 from exiting the type-C port. In the unlocked state, the locking member 120 can release the limiting protrusion 191, and the plug 110 can exit the type-C port. The locking assembly is installed on the lock body 100, and the locking assembly is used to drive the locking member 120 to move to switch the state of the locking member 120.

[0045] The embodiment of the utility model adopts a locking assembly to limit the locking member 120 and the limiting protrusion 191 to each other, wherein the locking assembly drives the locking member 120 to move, so that the locking member 120 and the limiting protrusion 191 are locked to each other, and the plug 110 cannot be pulled out, thereby realizing the locked state of the type-C port. When unlocking is required, the locking member 120 releases the limiting protrusion 191, thereby realizing the unlocked state of the type-C port. The mutual cooperation between the above-mentioned components, through the mutual locking of the locking member 120 and the limiting protrusion 191, the plug 110 cannot be easily pulled out, thereby ensuring that the type-C port is in a locked state. This design effectively prevents unauthorized access or operation and improves security. When unlocking, the locking assembly releases the limiting protrusion 191, so that the type-C port can be easily unlocked, thereby realizing the convenience of operation and ensuring the safety and reliability of the type-C port.

[0046] In some embodiments, the type-C port locking device also includes: a bracket 160, the bracket 160 is located in the plug, and the bracket 160 has a supporting surface; the locking member 120 includes a limiting portion 121 and a connecting portion 122 connected to a preset angle structure, and the locking assembly drives the limiting portion 121 to move, so that the limiting portion 121 swings relative to the supporting surface with the connection point between the limiting portion 121 and the connecting portion 122 as a fulcrum, and when the limiting portion 121 swings to different positions relative to the supporting surface, it switches to a locked state or an unlocked state accordingly.

[0047] In some embodiments, the limiting portion 121 switches to a locked state when attached to the support surface, and switches to an unlocked state when the limiting portion 121 is separated from the support surface.

[0048] In some other embodiments, the limiting portion 121 is switched to an unlocked state when attached to the support surface, and is switched to a locked state when separated from the support surface.

[0049] The locking member 120 is designed to have strong rigidity, and can withstand long-term use and frequent unlocking and locking operations without being easily damaged, thereby extending the service life of the locking device. The locking member 120 is composed of a connecting portion 122 and a limiting portion 121, and the two have a certain bending angle. When in use, the connection point between the limiting portion 121 and the connecting portion 122 is used as a fulcrum to form a lever structure, so that it can be unlocked in a very small space, and can effectively prevent unlocking or locking failure caused by misoperation or external vibration. At the same time, the common lever structure principle is used, and the design is relatively simple, which makes the manufacturing and maintenance of the locking member 120 relatively easy, reducing costs and complexity. When the locking device is unlocked, the locking assembly pushes the connection portion 122 of the locking member 120 downward, and the limiting portion 121 tilts upward to avoid the pin connector 190 inside the type-C port. At this time, the locking device can be freely plugged in and out; when the lock is locked, the locking assembly pushes the limiting portion 121 of the locking member 120 downward, and the limiting portion 121 cooperates with the protrusions on both sides of the pin connector 190 inside the type-C port to achieve mutual locking between the locking device and the type-C port, thereby improving the safety of the type-C port locking. In some embodiments, the limiting portion 121 includes two symmetrically arranged limiting claws 1211, and the two limiting claws 1211 are respectively provided with bending portions extending toward each other. In the locked state, the bending portions cooperate with the limiting protrusion 191. Through the symmetrically arranged two limiting claws 1211, it can be ensured that the limiting cooperation between the locking member 120 and the limiting protrusion 191 in the locked state is stable and reliable. The design of two limiting claws 1211 extending toward each other increases the contact area between the locking member 120 and the type-C port, and improves the stability of the connection. The setting of the bent portion can make the limiting cooperation between the locking member 120 and the limiting protrusion 191 more precise. The bending portion design of the limiting claw 1211 can withstand a certain amount of pressure and friction, thereby improving the durability of the locking member 120 in the locked state. The design of the limiting claw 1211 can adapt to limiting protrusions 191 of different shapes and sizes, thereby enhancing the applicability of the limiting portion 121. This design enables the locking member 120 to cooperate with various types of type-C ports, thereby improving the versatility of the locking device. The design of the limiting portion 121 can ensure that the locking member 120 is firmly matched with the limiting protrusion 191 in the locked state, thereby increasing the safety of the type-C port locking.

[0050] In some embodiments, the locking assembly includes a lock core 130 and a push rod 140. The lock core 130 is installed in the lock body 100. The push rod 140 is arranged in the lock body 100, and the push rod 140 is transmission-connected between the lock core 130 and the locking member 120. The rotational movement of the lock core 130 can drive the push rod 140 to reciprocate to switch the state of the locking member 120. The operator can control the state of the locking member 120 by rotating the lock core 130 to achieve the unlocking and locking of the type-C port, thereby improving the controllability and flexibility of the locking device. The push rod 140 is arranged inside the lock body 100, is not easily affected by the external environment, and maintains stability during movement.

[0051] In some embodiments, the lock core 130 has a built-in wireless code chip, and a computer key is inserted into the lock core 130 to read the code value of the wireless code chip to determine the identity.

[0052] Specifically, the computer key is inserted into the lock core 130, and the code value of the lock core 130 is read. If the code value is correct, the key rotates the lock core 130 clockwise, the locking assembly pushes the connecting part 122 of the locking member 120 downward, and the limiting part 121 tilts upward to avoid the pin connector 190 inside the type-C port. The locking device is pulled out of the type-C port, and the unlocking is completed.

[0053] The computer key is inserted into the lock core 130, and the code value of the lock core 130 is read. If the code value is correct, the key rotates the lock core 130 in the opposite direction, and the lock assembly pushes the limit portion 121 of the locking member 120 downward, and the limit portion 121 cooperates with the protrusions on both sides of the pin connector 190 inside the type-C port to achieve mutual locking between the locking device and the type-C port. The locking device cannot be pulled out, and locking is achieved. The technical problem of one-key-to-open and low security in the existing locking method is solved. At the same time, both unlocking and locking operations require code reading and authorization, and the lock status can be recorded and traced.

[0054] In some embodiments, the push rod 140 includes a sliding portion 141, the sliding portion 141 is provided with a protruding portion 1411 and a giving portion 1412, and the sliding portion 141 is slidably disposed in the lock body 100. The sliding portion 141 slides relative to the lock body 100 so that the protruding portion 1411 pushes the limiting portion 121 downward, and the connecting portion 122 enters the giving portion 1412, and the locking member 120 switches to a locked state; the sliding portion 141 slides relative to the lock body 100 so that the protruding portion 1411 pushes the connecting portion 122 downward, and the limiting portion 121 tilts up, and the locking member 120 switches to an unlocked state.

[0055] In some embodiments, the push rod 140 also includes a threaded portion 142 and a mounting portion 143, the sliding portion 141 and the threaded portion 142 are located at opposite ends of the mounting portion 143, the locking assembly also includes a rotating shaft 150, the rotating shaft 150 is connected to the lock core 130, the threaded portion 142 is inserted into the rotating shaft 150 and cooperates with the rotating shaft 150, the screw portion is provided with an internal thread, which cooperates with the external thread of the inner cavity of the rotating shaft 150, the lock core 130 drives the rotating shaft 150 to rotate, so that the push rod 140 reciprocates. In some embodiments, a double helix structure thread is provided on the threaded portion 142. The double helix structure is used to convert the rotational motion of the lock core into the forward and backward linear motion of the push rod, which has high transmission efficiency and strong load-bearing capacity.

[0056] In some embodiments, the mounting portion 143 is symmetrically provided with grooves 1431 , and the inner circumference of the lock body 100 is provided with guide columns, and the grooves 1431 and the guide columns are limitedly matched to allow the push rod 140 to slide smoothly inside the lock body 100 .

[0057] In some embodiments, a limiting groove 101 is provided on the inner circumference of the lock body 100 , and a preset blade of the lock core 130 is inserted into the limiting groove 101 to limit the rotatable angle of the lock core 130 .

[0058] In some embodiments, the type-C port locking device further includes a cover plate 170 , which is located inside the plug 110 . The cover plate 170 is fixedly connected to the bracket 160 , and the cover plate 170 is used to insulate and space the plug 110 from the pin connector 190 .

[0059] Specifically, the plug 110 is fixedly mounted on the outer end surface of the lock body 100 by screws. The bracket 160 is made of plastic and has a ring structure at the front end, which guides and positions the pin connector 190 inside the type-C port when the locking device is inserted into the type-C port, and prevents the plug 110 from short-circuiting the pins on the pin connector 190. The bracket 160 is also provided with a support block and a limit block, which are used to provide movement support for the ejector 140 and limit the cover 170 respectively.

[0060] In some embodiments, the type-C port locking device also includes an elastic member 180. The elastic member 180 is, for example, a spring. The elastic member 180 elastically abuts between the bracket 160 and the ejector rod 140, and the elastic member 180 provides power for the rebound of the ejector rod 140. A spring mounting cavity is provided on the central axis of the mounting portion 143 for placing the elastic member 180. Under the action of the elastic force, the ejector rod 140 is always in contact with the rotating shaft 150, and provides a certain rebound force to drive the ejector rod 140 to move horizontally backward when unlocked. In some other embodiments, the elastic member 180 may also be arranged in other ways, as long as the above-mentioned effects can be achieved.

[0061] The above are only preferred embodiments of the present invention, and do 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 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.
