When locking device is in locking state, control piece is located at upper lock position, and control piece is limited, and control piece prevents contiguous block 3
Moved to using position, usb 10 is in off position；When locking device is in unlocking condition, contiguous block 3 is movable to use
Position and usb 10 is movable to via positions.
For the technical program when implementing, locking device is generally mechanical lock, such as coded lock, key lock, naturally it is also possible to electricity
Son lock；Control piece in locking device is controlled by lock status, and when locking device is located at locking state, control piece is typically in limit
Position state or positioned at upper lock position, limits the movement of contiguous block 3；When locking device is unlocking condition, control piece is located at movable shape
State now no longer limits one end of contiguous block 3 positioned at lockset position of coupler, control piece, or directly contiguous block 3 is moved to using position
Put.Now USB interface can be moved to via positions.
Secondly, between usb 10 and the mainboard of computer here and it is indirect connected by data wire, but in computer
With set on usb 10 set respectively corresponding to contact, when the corresponding contact of both sides abuts, usb 10 is in path
Position simultaneously electrically connects with the mainboard of computer.Locking device is played by controlling the connection status between usb 10 and mainboard
The effect locked to usb 10.When in use, USB is locked and combined with smart machines such as computer, notebooks；By machinery
Locking is due on smart machine.USB locks are locked for built-in machines.
When positioned at lockset position of coupler, USB flash disk etc. can by grafting usb 10 and promote usb 10 positioned at connection position
Put to use.
Further, locking device includes mechanical code lock, and it includes housing 1, at least three password wheel unit 2 and motion bar
5, motion bar 5 is the control piece, and housing 1 is provided with the mounting hole being engaged with password wheel unit 2, and password wheel unit stretches out shell
Body 1, one end of motion bar 5 sequentially passes through described password wheel unit 2 and is connected with contiguous block 3, when password wheel unit 2 is respectively positioned on
During password correct position, motion bar 5 can move relative to password wheel unit 2；When one of password wheel unit 2 is located at code error position
Put, motion bar 5 is limited.
The combination of password wheel unit 2 and motion bar 5, can be the prior art of mechanical code lock；Pass through password wheel unit 2
Password adjust and control the working condition of motion bar 5, at least three password wheel unit 2 here includes one and above password
Wheel unit 2.Certainly, locking device can also include key lock, and key lock includes lock core, and lock core connects the control piece, works as key
During unlocking, control piece leaves upper lock position（The place i.e. outside the motion track of contiguous block 3）, contiguous block 3 can be with USB
Interface 10 moves；In specific design, housing 1 is formed by connecting by upper shell 11 and lower house 12.
Housing 1 can be the housing of notebook computer or desktop computer.
Further, the side of motion bar 5 is provided with spacing block set 51, and the medial surface of password wheel unit is provided with and spacing block set
The annulus 221 of 51 bands being engaged jagged 224；When password wheel unit password is correct, spacing block set 51 is relative with breach 224
Should.
Here password wheel unit can originally be set and no longer be adjusted with an entirety, password.
Yet further, the password wheel unit includes being located at the password wheels 21 in outside and is placed on the left regulation wheel of inner side,
The annulus 221 is located at the medial surface of left regulation wheel；The one end of the medial surface of password wheels 21 away from contiguous block 3 extends internally out multiple
Gap is formed between raised 211, raised 211；The left regulation wheel is provided with spacing ring 223 and spacing ring close to one end of contiguous block 3
223 stretch out the fixture block 222 being engaged for gap, and the described one end of housing 1 away from contiguous block 3 is provided with can relative housing 1
Mobile regulating block 7, regulating block 7 are provided with the adjustment portion for stretching out housing 1；Housing 1 is provided with close to one end of contiguous block 3 to be used to aid in
The elastic component for adjusting code wheel 22 to reset.
Password wheel unit is arranged to password wheels 21 and adjusts the Split type structure of code wheel 22, password wheels 21 can be adjusted.Specially：
When password is correct, regulating block 7 is promoted to move by adjustment portion so that the fixture block 222 of bar code wheel separates with gap, now bullet
Property part deforms upon；Then password wheels 21 are selected to adjust password；After password adjusts, adjustment portion is unclamped, adjusts code wheel 22 in elasticity
Resetted under the promotion of part.Elastic component can be spring 6, and one end abuts with tune code wheel 22, the other end and contiguous block 3 or housing 1
Abut.
Preferably, be additionally provided with shell fragment in the housing, shell fragment is provided with the elastic portion being engaged with password wheels 21, elastic portion with
Password wheels 21 offset.
The surface of password wheels 21 is provided with digital pattern, and elastic portion offsets with password wheels 21 so that password wheels 21 rotation when
Wait, by the resistance of elastic portion so that the operation of password wheels 21 has power sense；Password wheels 21 are also avoided arbitrarily to rotate simultaneously.
Further, the side of the housing 1 is provided with mounting hole, and drive block 4, one end of drive block 4 are provided with mounting hole
Housing 1 is stretched out, the other end of drive block 4 is provided with skewback, and the contiguous block 3 is provided with the inclined-plane 31 being engaged with skewback；Work as driving
When block 4 moves into housing 1, drive block 4 promotes contiguous block 3 to be moved to locking device direction.
By setting drive block 4 to be controlled from side to contiguous block 3.So that operation enhanced convenience.Preferably,
The middle part of the contiguous block 3 is provided with jack, and the end of drive block 4 is provided with inserted block, and the inclined-plane 31 is arranged at the side of jack, institute
It is the skewback to state inserted block.Jack and inserted block are designed, can effectively be reduced compacter using space, structure.
Yet further, the drive block 4 is provided with guide part 41, and the housing 1 is provided with and led with what guide part 41 was engaged
To groove.
Guide part 41 and guide groove are set so that drive block 4 can do displacement.Avoid rocking in housing 1.
