Abstract
Description
Technical Field
[0001] This utility model relates to the field of USB technology, specifically to a USB security lock with dual unlocking heads. Background Technology
[0002] USB is a data connection interface that allows you to connect to a computer and read or transfer information and data inside the computer. On some important computers, it is necessary to lock the computer's USB interface to prevent the leakage of information inside the computer, hence the need for a USB lock.
[0003] USB interface locks typically use a lock to lock the interface. The lock has an unlocking port, but existing locks only have one unlocking port. When cracked, only one unlocking port needs to be cracked to open the lock, resulting in low security. Utility Model Content
[0004] The purpose of this invention is to provide a USB security lock with dual unlocking heads to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a USB security lock with dual unlocking heads, comprising an unlocking component, the unlocking component being equipped with a USB lock component, the unlocking component having dual unlocking heads on one side, the USB lock component including a housing, a snap fastener fixedly disposed inside the housing, the housing having dual unlocking ports on the side facing the unlocking component, damping components being disposed on both sides of the housing, one of the dual unlocking ports being a minus sign shape and the other being a plus sign shape.
[0006] Preferably, the fastener is provided with an inclined slide, and a snap-fit end is provided on one side of the inclined slide.
[0007] Preferably, the dual unlocking heads are matched with the dual unlocking ports and the buckle to form a dual-lock dual-key structure; in forming a dual-lock dual-key structure, the lock hole shapes of the dual unlocking ports are different, and the lock head structures of the dual unlocking heads are also different.
[0008] Preferably, the USB lock assembly is integrally cast and molded, and the USB lock assembly is elastic.
[0009] Compared with the prior art, the beneficial effects of this utility model are: by using dual unlocking heads and dual unlocking ports to unlock the USB lock component, it is necessary to unlock two unlocking ports at the same time. Since the USB lock component is small in size, it is difficult to crack two unlocking ports at the same time, thus improving the security of the USB interface. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0016] Please refer to 1-4. One embodiment of this utility model is provided: a USB security lock with dual unlocking heads, including an unlocking component 1, a USB lock component 2, a dual unlocking head 3 on one side of the unlocking component 1, a housing, a latching member 4 fixedly installed inside the housing, a dual unlocking port 5 on the side of the housing facing the unlocking component 1, and damping members 6 on both sides of the housing. One of the dual unlocking ports 5 is in the shape of a minus sign and the other is in the shape of a plus sign. The damping member 6 can provide feedback when the USB lock component 2 enters the USB interface, and at the same time facilitates fixing it to the USB interface. When the USB lock component 2 is inserted into the USB interface, the latching member 4 is used to lock it to the USB interface. When unlocking is required, the dual unlocking head 3 of the unlocking component 1 must be inserted into the dual unlocking port 5 to squeeze the latching member 4, so that the USB lock component 2 can be unlocked and disengaged from the USB interface.
[0017] The buckle 4 is provided with an inclined slide 41, and a snap-fit end 42 is provided on one side of the inclined slide 41. After the double unlocking head 3 enters the inclined slide 41, it squeezes the inclined slide 41, causing the buckle 4 to move downward as a whole, which in turn moves the snap-fit end 42 downward, thereby causing the USB lock assembly 2 to disengage from the USB interface.
[0018] The double unlocking head 3 matches the double unlocking port 5 and the latch 4 to form a double lock and double key structure. The lock hole shapes of the double unlocking ports 5 are different, and the lock head structures of the double unlocking heads 3 are also different. One of the unlocking heads of the double unlocking head 3 is a horizontal key and the other is a vertical key. The horizontal key is inserted into the minus-shaped double unlocking port 5, and the vertical key is inserted into the plus-shaped double unlocking port 5. They need to be unlocked at the same time to open the lock.
[0019] The USB lock component 2 is integrally cast, resulting in low manufacturing costs. The USB lock component 2 is elastic, which facilitates the rebound of the latch 4, making it easier to lock and unlock the USB interface.
[0020] Working principle: When in use, the USB lock component 2 is inserted into the USB interface, so that the latching end 42 of the latch 4 abuts and presses against the upper end of the USB interface to lock the USB interface. When unlocking is required, the double unlocking head 3 of the unlocking component 1 enters from the double unlocking port 5 and enters the inclined slide 41, moving the latch 4 downward as a whole, so that the latching end 42 disengages from the upper end of the USB interface, thereby unlocking.
