Abstract
The invention provides a computer key unlocking device which comprises a shell, an unlocking rod, a locking shaft, a moving part and an unlocking module part, wherein the unlocking rod comprises a main body part and a head part; the moving part comprises a release pin, a connecting piece with a moving cavity, an electromagnet and a push-pull rod which can axially enter and exit along the electromagnet; the unlocking module component is used for sending a signal to the electromagnet, so that the push-pull rod is driven to move towards the direction far away from the unlocking rod, the unlocking pin is attracted by magnetic force to move towards the direction far away from the unlocking rod, and the locking shaft is switched from a rotation limited state to a free rotation state. Because the electromagnet and the push-pull rod do not directly participate in the locking/unlocking action of the movement of the locking shaft, the phenomenon that the unlocking mechanism cannot normally unlock due to the fact that the electromagnet is damaged by external force is avoided.

Technical Field
The invention relates to the field of transformer substation misoperation-preventive locking, in particular to a computer key unlocking device.
Background
The existing computer keys mostly use an electromagnet push-pull rod to lock/unlock the movement of an unlocking mechanism, and the implementation mode is divided into a direct type or an indirect type. The former uses an electromagnet push-pull rod to directly bear the torque force of the unlocking mechanism, and the torque force directly acts on the push-pull rod during forced unlocking, so that the push-pull rod and a rotating shaft and other elements in contact with the push-pull rod are easily damaged to influence the smoothness of unlocking operation. Compared with a direct unlocking mechanism, the indirect unlocking mechanism structure uses an indirect element instead of an electromagnet push-pull rod to bear torsion, and the size of the unlocking mechanism structure with a complex structure can be increased, so that the power consumption of the electromagnet and the miniaturization difficulty of a computer key are increased.

In one embodiment, the head is provided with a stepped recess.
In one embodiment, the head is further provided with a pair of protrusions matched with the five-prevention lockset. .
In one embodiment, the top of the housing further comprises a code reading member.
In one embodiment, the tail of the main body is provided with an opaque blocking piece.
In one embodiment, the unlocking pin and the push-pull rod are made of soft magnetic materials.

Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. The invention is further illustrated by the figures and examples of the present application.
As shown in fig. 1, the computer key unlocking device according to the embodiment of the present invention includes a housing 100; an unlocking lever 200 including a body portion 210 and a head portion 220; the locking shaft 300, the locking shaft 300 is sleeved on the periphery of the main body part 210, and the locking shaft 300 is provided with a locking hole 310; the moving part 400 comprises a release pin 440, a moving cavity 430, an electromagnet 410 and a push-pull rod 420 which can move in and out along the axial direction of the moving part, the release pin 440, the electromagnet 410, the push-pull rod 420 and the moving cavity 430 are on the same central axis, and the release pin 440 and the push-pull rod 420 can move along the central axis of the moving cavity 430; and the unlocking module component is used for sending a signal to the electromagnet 410 so as to drive the push-pull rod 420 to move towards the direction far away from the unlocking rod 200 and attract the unlocking pin 440 to move towards the direction far away from the unlocking rod 200 through magnetic force, so that the locking shaft 300 is switched from the rotation limited state to the free rotation state.
Referring to fig. 2, the electromagnet 410 pushes the push-pull rod 420 and the unlocking pin 440 into the locking hole 310 by its own spring force, and the unlocking mechanism is in a non-unlocking state, limiting the relative rotation of the locking shaft 300 and the housing 100; referring to fig. 3, the unlocking module sends a signal to the electromagnet 410 to suck the push-pull rod 420 back, and the magnetic force drives the unlocking pin 440 to disengage from the locking hole 310, so that the unlocking mechanism is in an unlocked state, and the relative rotation restriction of the locking shaft 300 and the housing 100 is released. Because the electromagnet 410 and the push-pull rod 420 do not directly participate in the locking/unlocking action of the movement of the locking shaft 300, the situation that the unlocking mechanism cannot normally unlock due to the electromagnet 410 being damaged by external force is avoided.
In one embodiment, as shown in fig. 1, the head 220 is provided with a stepped groove 230 for unlocking the mechanical cylinder of the five-prevention lock.
In one embodiment, as shown in fig. 1, the head 220 is further provided with a pair of protrusions 240 cooperating with the five-prevention lock, and the five-prevention lock is directly or indirectly driven by the mechanical lock cylinder to be turned and unlocked.
In one embodiment, as shown in fig. 1, the top of the housing 100 further includes a code reading component 500, and when the five-prevention lock code is correctly read, the unlocking module component sends an unlocking signal to the electromagnet 410.
In one embodiment, as shown in fig. 1, an opaque blocking piece 600 is provided at the rear of the body 210, and rotates synchronously with the unlocking lever 200, so as to detect whether the unlocking rotation is in place during the operation of the electric lock.
In one embodiment, as shown in fig. 1, the unlocking pin 440 and the push-pull rod 420 are soft magnetic materials.
In one embodiment, as shown in fig. 1, a pair of metal electrodes 700 is disposed on two sides of the housing 100, and is connected to the conductive electrodes of the electric lock for performing an operation and an electroscopy operation.
In one embodiment, as shown in fig. 1, the unlocking pin 440, the moving chamber 430, and the electromagnet 410 are axially perpendicular to the unlocking lever 200.
In one embodiment, as shown in fig. 4, the unlocking pin 440, the moving chamber 430, and the electromagnet 410 may also be axially parallel to the unlocking lever 200.
In one embodiment, as shown in fig. 1, the unlocking pin 440 is in non-contact connection with the push-pull rod 420, so that the external force received by the unlocking pin 440 is not transmitted to the push-pull rod 420, thereby preventing damage to the electromagnet 410.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
