the compensation locking mechanism 4 is disposed outside the second locking through hole, the compensation locking mechanism 4 is provided with a second locking shaft 41, the second locking shaft 41 is movably telescopic in the second locking through hole, when the unlocking device is in a locking state and the first locking shaft 31 retracts due to shaking, the second locking shaft 41 of the compensation locking mechanism 4 is accommodated in the second locking portion 22 and limits the unlocking transmission member 2 to slide in the chute 11, and when the unlocking device is in an unlocking state, the second locking shaft 41 cannot extend into the second locking portion 22.
In the unlocking device for preventing accidental unlocking, when the unlocking device is normally locked, the unlocking mechanism 3 moves towards the unlocking transmission piece 2 so as to clamp the unlocking transmission piece 2; when the lock is normally unlocked, after the unlocking mechanism 3 moves towards the direction far away from the unlocking transmission part 2, an operator pushes the unlocking transmission part 2 to slide in the lock body 1 so as to realize unlocking. When the unlocking device in the normal locking state is shaken, the first locking shaft 31 of the unlocking mechanism 3 retracts towards the direction far away from the first locking part 21 due to shaking, and the second locking shaft 41 of the compensation locking mechanism 4 moves towards the direction of the second locking part 22 under the action of gravity or electromagnetic force so as to clamp the unlocking transmission member 2, so that the unlocking device is still in the locking state, and the situation that the unlocking device is locked and disabled and a computer key loses the function of preventing misoperation is avoided. The first locking through hole and the second locking through hole are arranged on two opposite sides of the groove wall of the sliding groove 11, so that the unlocking mechanism 3 and the compensation locking mechanism 4 are arranged on two opposite sides of the groove wall of the sliding groove 11, the unlocking mechanism 3 and the compensation locking mechanism 4 can be mutually matched to form complementation when shaking occurs, and the influence of acting force generated when shaking on the locking function of the unlocking mechanism 3 is overcome.
The first locking part 21 is a first groove, and the first locking part 21 is arranged at the lower side of the unlocking transmission piece 2 perpendicular to the sliding direction of the unlocking transmission piece;
the second locking portion 22 is a second groove, and the second locking portion 22 is opened on the upper side of the unlocking transmission member 2 perpendicular to the sliding direction of the second locking portion;
the unlocking mechanism 3 includes a first electromagnet 32, one end of the first locking shaft 31 faces the first locking portion 21, and the other end of the first locking shaft 31 faces the first electromagnet 32.
The first locking shaft 31 is made of iron, cobalt, nickel, or the like that can be attracted by the first electromagnet 32 after being energized.
In normal locking, the first electromagnet 32 is not energized, and the first locking portion 21 is accommodated in the first locking portion 21. During normal unlocking, the first electromagnet 32 is energized to generate a magnetic field, the magnetic field attracts the first locking shaft 31 to drive the first locking shaft 31 to move in a direction away from the first locking part 21 and leave the first locking part 21, and an operator pushes the unlocking transmission member 2 to slide in the lock body 1 to realize unlocking.
It is worth to say that the first elastic element 33 is connected between the first locking shaft 31 and the first electromagnet 32;
when the unlocking device is in a locked state, the first elastic element 33 pushes the first locking shaft 31 to extend towards the first locking part 21 and be accommodated in the first locking part 21;

In normal locking, the first electromagnet 32 is not energized and does not attract the first locking shaft 31, and the first elastic element 33 pushes the first locking shaft 31 to be accommodated in the first locking portion 21 by an elastic force. After the first electromagnet 32 is energized to generate a magnetic field, the attraction force of the magnetic field to the first locking shaft 31 is greater than the elastic force of the first elastic element 33 to the first locking shaft 31, and the first locking shaft 31 moves toward the first electromagnet 32 and moves away from the first locking portion 21, so that unlocking can be achieved.
Optionally, the compensating locking mechanism 4 further comprises a driving member and a second elastic element 43, one end of the second locking shaft 41 faces the second locking portion 22, the other end of the second locking shaft 41 faces the driving member, and the second elastic element 43 is connected between the second locking shaft 41 and the driving member;
the second elastic element 43 is used for pushing the second latching shaft 41 to be inserted into the second locking part 22 by elastic force or pushing the second latching shaft 41 to be separated from the second locking part 22 by elastic force;
the driving member is used to drive the second latching shaft 41 to disengage from the second locking part 22 or to insert into the second locking part 22 against the elastic force of the second elastic member 43.
The driving member and the second elastic member 43 interact with each other to allow the second latching shaft 41 to be moved out of the second locking portion 22 or inserted into the second locking portion 22.
In some embodiments, the second elastic member 43 is used to push the second latching shaft 41 to be inserted into the second locking part 22 by elastic force; the driving member is used to drive the second latching shaft 41 to disengage from the second locking part 22 against the elastic force of the second elastic member 43. For example, the driving member may be a motor having its own power source, an electromagnet, a micro cylinder, etc., and in the locked state, the second elastic member 43 pushes the second locking portion 22 to be inserted into the second locking portion 22 by elastic force, and in the case that the first locking shaft 31 is retracted due to shaking, the unlocking device is also ensured to be in the locked state; in the unlocked state, the driving member drives the second latching shaft 41 to disengage from the second locking portion 22 against the elastic force of the second elastic element 43, and the unlocking device can unlock through the unlocking mechanism 3.
In still other embodiments, the second elastic element 43 is used for driving the second latching shaft 41 to disengage from the second locking part 22 by elastic force; the driving member is used to drive the second latching shaft 41 to be inserted into the second locking part 22 against the elastic force of the second elastic member 43. For example, the driving member may be a counterweight without a power source, when the unlocking mechanism is not shaken, the second elastic element 43 drives the second locking shaft 41 to disengage from the second locking portion 22 by an elastic force, and the unlocking device can be unlocked or locked by the unlocking mechanism 3; when the lock body is shaken, the driving member drives the second latching shaft 41 to be inserted into the second locking portion 22 against the elastic force of the second elastic member 43, so that the unlocking device can be ensured to be in a locked state when the first latching shaft 31 is retracted due to shaking.
Example 2
This example was modified from example 1 as follows: the driving member of this embodiment includes a second electromagnet 42, one end of the second latching shaft 41 faces the second locking part 22, and the other end of the second latching shaft 41 faces the second electromagnet 42;
when the unlocking device is in the locked state, the second elastic element 43 pushes the second locking shaft 41 to extend toward the second locking portion 22 and be accommodated in the second locking portion 22;
when the unlocking device is in the unlocked state, the second latching shaft 41 is retracted away from the second locking portion 22 against the elastic force of the second elastic element 43 after the second electromagnet 42 is energized.
The second locking shaft 41 is made of a material such as iron, cobalt, or nickel that can be attracted by the second electromagnet 42 after the energization.
As shown in fig. 1, in the normal locking state, the second electromagnet 42 is not energized, and the second locking portion 22 is accommodated in the second locking portion 22. When the unlocking device in the normal locking state is shaken, and the shaking force is upward, the first locking shaft 31 of the unlocking mechanism 3 can retract downwards relative to the first locking part 21 under the action of inertia to leave the first locking part 21, at this time, the second locking shaft 41 can be clamped with the second locking part 22 more tightly under the action of inertia, and when the shaking force is downward, the first locking shaft 41 of the unlocking mechanism 3 can be clamped with the first locking part 21 more tightly under the action of inertia, so that the situation that the locking of the unlocking device fails when the unlocking mechanism 3 is shaken and retracts is avoided.
When the lock body is normally unlocked, the second electromagnet 42 is energized to generate a magnetic field, the magnetic field attracts the second locking shaft 41 to drive the second locking shaft 41 to move away from the second locking part 22 and leave the second locking part 22, and in addition, the first locking shaft 31 is in a retraction state, so that an operator pushes the unlocking transmission member 2 to slide in the lock body 1 to realize unlocking.
Example 3
This example was modified from example 1 as follows: the driving member of this embodiment includes a weight 44, one end of a second elastic element 43 is fixedly connected with the lock body 1, one end of the second locking shaft 41 faces the second locking portion 22 and is disposed in the second elastic element 43 in a penetrating manner, the other end of the second locking shaft 41 is mounted with the weight 44, and the weight 44 is abutted against and connected with the other end of the second elastic element 43;
the second elastic element 43 is used for driving the second latching shaft 41 to be disengaged from the second locking part 22 by elastic force;
the weight 44 is used to drive the second latching shaft 41 to be inserted into the second locking portion 22 against the elastic force of the second elastic member 43.
As shown in fig. 2 and 3, in normal locking and unlocking, the elastic force of the second elastic element 43 is greater than the weight 44 and the weight of the second locking shaft 41, the second elastic element 43 jacks up the weight 44 and the second locking shaft 41 by the elastic force, and one end of the second locking shaft 41 leaves the second locking portion 22, so that unlocking can be achieved by the unlocking mechanism 3. When the unlocking device is shaken and the shaking force is upward, due to the action of inertia, the gravity of the weight block 44 and the second locking shaft 41 plus the shaking force is larger than the elastic force of the second elastic element 43, the weight block 44 drives the second locking shaft 41 to move towards the direction of the second locking part 22, one end of the second locking shaft 41 is clamped in the second locking part 22, the unlocking transmission member 2 can be limited to slide, and the situation that the unlocking device is locked and disabled due to the fact that the first locking shaft 31 retracts towards the direction away from the second locking part 22 during shaking is avoided.
It is worth noting that the weight of the weight 44 plus the second locking shaft 41 is greater than the weight of the first locking shaft 31.
This has the advantage that the inertia of the weight 44 and the second locking shaft 41 is greater than that of the first locking shaft 31, and when the first locking shaft 31 retracts in a direction away from the first locking portion 21 under the shaking of an external force, the weight 44 can drive the second locking shaft 41 to be locked into the second locking portion 22 to limit the unlocking transmission member 2 from sliding.
Optionally, one end of the second locking shaft 41 is provided with a snap-in portion 46 having a diameter larger than that of the second elastic member 43.
The clamping portion 46 serves as a limit, and after the second locking shaft 41 passes through the second elastic element 43, the second locking shaft 41 can be prevented from being separated from the second elastic element 43 in the process of being jacked up.
Specifically, as shown in fig. 4, a mounting bracket 12 is disposed at the second locking through hole of the lock body 1, a mounting hole 13 coaxial with the second locking through hole is formed in the mounting bracket 12, one end of the second elastic element 43 is disposed in the mounting hole 13 and is fixedly connected to an inner wall of the mounting hole 13, and one end of the second locking shaft 41 is disposed in the mounting hole 13 in a penetrating manner and moves up and down in the mounting hole 13.
When the locking device is installed, one end of the second elastic element 43 is fixedly installed in the installation hole 13, and then one end of the second locking shaft 41 passes through the installation hole 13, and the other end of the second locking shaft 41 is installed with the counterweight 44, so that the second locking shaft 41 can be limited, and the second locking shaft 41 is prevented from being separated from the lock body. When the second locking shaft 41 moves up and down in the mounting hole 13, the function of compensation locking can be realized, and the condition of locking failure is avoided.
Preferably, as shown in fig. 3 and 4, the upper end of the weight block 44 is fixedly connected to the other end of the second locking shaft 41 by a snap spring 45.
During installation, the counterweight block 44 is firstly sleeved on the outer wall of the other end of the second locking shaft 41, and then the clamp spring 45 is clamped into the clamp groove preset at the other end of the second locking shaft 41, so that the counterweight block 44 is limited to move upwards and be separated from the second locking shaft 41.
