This embodiment provides a cabinet opens and shuts, includes: a cabinet door, a cabinet body, a hanging buckle 21 and a lockset device. Wherein, the cabinet door can be arranged on the cabinet body in an opening and closing way; the hanging buckle 21 is detachably installed with the lockset device; the lockset device is arranged on one of the cabinet door and the cabinet body, and the hanging buckle 21 is arranged on the other of the cabinet door and the cabinet body. For example, the catch 21 is mounted on the cabinet door and the lock device is mounted on the cabinet body. The cabinet door and the cabinet body are provided with the hanging buckle 21 or the lockset device which can be adjusted according to specific use conditions.

Specifically, the latch device in the present embodiment, as shown in fig. 1 to 4, includes: the casing 4, spring bolt 11, actuating mechanism and drive mechanism. Specifically, the latch 11 is slidably mounted in the housing, the driving mechanism is located in the housing 4 and includes an attraction member and a driving member, the attraction member is magnetically connected to the driving member, the attraction member is connected to the housing, and the driving member is capable of moving toward a direction close to or away from the attraction member. The transmission mechanism includes a transmission member 131 and a first biasing member 132. The transmission member 131 is rotatably disposed on the housing 4 with the rotation fulcrum O as a rotation axis; the bolt 11 and the driving member are disposed on two sides of the driving member 131, and are respectively connected to the bolt 11 and the driving member. In this embodiment, the mode that the bolt 11 is installed upwards is adopted.

As shown in fig. 2, 3 and 4, in the present embodiment, the driving mechanism further includes a controller. The controller is electrically connected with the suction piece to control the on-off of the suction piece; the attraction member is energized to generate magnetism. The suction piece is fixedly arranged on the shell; the driving piece is arranged in a slidable mode relative to the attraction piece, and when the driving piece is powered on, the driving piece and the attraction piece attract each other.

The engaging member in this embodiment is an electromagnet 121, and the driving member is a magnetic core 122. As shown in fig. 4, a connecting plate is disposed on the top of the magnetic core, and a connecting hole is disposed on the connecting plate, specifically, the connecting hole is a round hole, but may also be a square hole in other alternative embodiments. The magnetic core 122 is connected to the transmission member 131 through the connection hole. The right end of the driving member 131 is inserted into the connecting hole in fig. 2 and 3. In the connection manner between the electromagnet 121 and the magnetic core 122, as shown in fig. 4, an accommodating cavity for accommodating the magnetic core 122 is arranged in the electromagnet 121, a guide post is connected below the magnetic core 122, and the magnetic core 122 extends into or moves out of the accommodating cavity through the guide post, so that the magnetic core 122 is close to or away from the electromagnet 121.

In the present embodiment, the lock device has an unlocked state and a locked state, wherein in the unlocked state, the electromagnet 121 and the magnetic core 122 are attracted to each other, and the lock tongue 11 and the hanging buckle 21 are separated from each other; in the locked state, the electromagnet 121 and the magnetic core 122 are separated, and the lock tongue 11 and the hanging buckle 21 are locked with each other.

Specifically, the specific movement of the drive mechanism is as follows: the electromagnet 121 is powered on under the driving of the controller to generate a magnetic field, and then the magnetic core 122 moves towards the electromagnet 121 to drive the lock device to be switched to an unlocking state, so that the stability and reliability of the lock device in place during unlocking are guaranteed. When the electromagnet 121 is powered without being driven by a controller, no magnetic field is generated in the electromagnet 121, and the magnetic core 122 and the electromagnet 121 are separated from each other, and at this time, the magnetic core 122 is only subjected to self gravity and is not subjected to the magnetic force of the electromagnet 121. The arrangement of the driving mechanism further ensures that the lock device is in a locking state that the lock tongue 11 and the hanging buckle 21 are mutually locked, and further ensures the stability of the lock device in the locking state.

In the present embodiment, a first gravitational moment of the latch 11 relative to the pivot point O is greater than a second gravitational moment of the driving mechanism relative to the pivot point O. Therefore, even if all the elastic parts are invalid, the lock tongue 11 in the locking state is still kept at the locking position under the condition of fire or high temperature, so that the influence of the fire on the position of the lock tongue 11 is avoided, the spreading of dangers such as the fire and the like is prevented, and the safety of the lockset device is further improved.

For example, as shown in fig. 2, 3 and 4, the rotation fulcrum O of the transmission member 131 is disposed at a position between the latch bolt 11 and the driving mechanism, and the rotation fulcrum O is disposed closer to the latch bolt 11 than the driving mechanism, and the arm of the first gravitational moment is: the distance between the rotating fulcrum O and the connecting point of the lock tongue and the transmission part; the force arm of the second moment of weight is: the distance between the rotating fulcrum O and the connecting point of the lock core and the transmission piece.

For example, the transmission member 131 is a V-shaped rod, the transmission member 131 is connected with the bolt 11 in a sliding manner, and the transmission member 131 is connected with the driving mechanism in a sliding manner, for example, the transmission member 131 is in contact with the bolt 11 in a surface-to-surface contact manner and slides, and the transmission member 131 is in sliding connection with the magnetic core 122 through a slotted hole.

The first biasing member 132 in this embodiment is a torsion spring, one end of the torsion spring is fixedly disposed on the limiting protrusion on the housing 4, and the other end of the torsion spring is fixedly hooked on the transmission member 131; as shown in fig. 2, 3 and 4, the first biasing member 132 has a first biasing force that drives the driving member 131 to lock the latch 11. The first biasing force of the first biasing member 132 is a torsional elastic force generated by a torsion spring. When the electromagnet 121 is not powered on, the transmission member 131 can drive the magnetic core 122 to return to the locking position under the action of the elastic force of the torsion spring, and at this time, the transmission member drives the lock tongue to move towards the locking direction, so that the lock tongue is kept at the locking position. When the electromagnet 121 is energized, the magnetic core 122 moves downward when the magnetic attraction of the electromagnet 121 is applied to the magnetic core 122 to change the position from the position shown in fig. 2 to the position shown in fig. 3, and at this time, the magnetic core 122 still overcomes the elastic force of the torsion spring to achieve the attraction action of the magnetic core 122.

In this embodiment, the lock device further includes a second biasing member 14, one end of the second biasing member 14 abuts on the housing 4, and the other end abuts on the latch 11, and the second biasing member 14 has a second biasing force for driving the latch 11 to latch. The secondary biasing member 14 is a spring. The second biasing member 14 is in a compressed state when in a locking state, so that the reliability of the locking position of the lock bolt can be ensured when the lock bolt is locked in the using process, and the using safety of the lock device is further improved.

In this embodiment, the latch 11 further has a failure driving end 111 extending out of the housing 4, and the failure driving end 111 is driven by an external force to slide along the housing 4. For example, when the electromagnet 121 cannot be energized to attract the magnetic core, 122 may lift the faulty driving end 111 towards a direction away from the housing 4, so as to separate the lock tongue 11 from the hanging buckle 21, thereby realizing unlocking, ensuring that a fault handling countermeasure is provided for the lock device, and improving user experience. In the present embodiment, the fail driving end 111 is integrally formed with the latch 11. The second biasing member 14 is located in the housing 4 and sleeved at the failure driving end 111, when the latch bolt is in a locking state with the buckle, the second biasing member 14 is in a compression state, and the latch bolt is kept at a locking position under the elastic force of the second biasing member 14.

The tongue mouth of the locking tongue 11 in this embodiment is an inclined surface structure, and the inclination between the inclined surface and the horizontal plane may preferably be 40 degrees to 50 degrees, and in this embodiment, 45 degrees may be adopted.

As shown in fig. 2, 3 and 4, the opening and closing cabinet in this embodiment further includes: a rod body 22 and a third biasing member 23. Wherein, the rod body 22 is fixed with the hanging buckle 21 and extends into the shell 4; a third biasing member 23, which is sleeved on the rod body 22, wherein one end of the third biasing member 23 is fixedly connected with the rod body 22, and the other end of the third biasing member 23 is arranged in the shell 4; the third biasing member 23 has a third biasing force that drives the catch 21 in a direction away from the bolt 11. The third biasing member 23 is a spring. When the latch bolt and the catch are in the locked state, the third biasing member is in a compressed state. The third biasing member 23 ensures that when the lock tongue 11 is disengaged from the position of the locked state, the hanging buckle 21 can move towards the unlocking direction under the action of the third biasing force of the third biasing member 23, so as to be separated from the lock tongue 11, and further ensure the accuracy of the unlocking state.

In the opening and closing cabinet in this embodiment, the lock device further includes a first in-place detection assembly 31 and a second in-place detection assembly 32. The first in-place detection component 31 is arranged close to one side of the hanging buckle 21. The first in-place detecting assembly 31 has a first detecting end for detecting the position of the hanging buckle 21. When the buckle 21 is locked with the tongue 11, the first detection end abuts against the buckle 21, so that the first in-place detection assembly 31 is closed. The second in-place detection assembly 32 is disposed near one side of the lock tongue 11, and the second in-place detection assembly 32 is used for detecting the position of the lock tongue 11. The second in-place detection assembly 32 has a second detection end, and when the lock tongue 11 is separated from the hanging buckle 21, that is, when the lock tongue is in the locking device, the second detection end abuts against the lock tongue.

The first in-place detection assembly 31 and the second in-place detection assembly 32 may both be limit switches. Through the arrangement of the first detection assembly and the second detection assembly, the locking state and the unlocking state can be monitored, so that the accuracy of the in-place of the internal components of the locking state device is realized, and the accuracy of in-place is improved. In this embodiment, the first detection assembly and the second detection assembly are both connected to the controller. When the lock is closed, when the rod body of the hanging buckle reaches the lock closing position, the rod body can be abutted against the first in-place detection assembly 31, so that the first in-place detection assembly 31 is closed to form a passage, at the moment, the controller detects a trigger signal of the first in-place detection assembly 31, and the second in-place detection assembly 32 is in an open state to indicate that the lock is closed successfully. When the controller detects the trigger signal of the second in-place detection component 32 and the first in-place detection component 31 is in an open state, the unlocking is successful. In other optional embodiments, only the first in-place detection assembly 31 or only the second in-place detection assembly 32 may be provided, and the detection and indication of the state of the lock tongue may also be implemented to ensure that the position of the lock tongue is detected.

The switch cabinet in this embodiment is specifically used as follows:

when the door is used under a normal condition, if the cabinet door needs to be opened, firstly, a door opening instruction is issued or a two-dimensional code scanning door opening instruction is sent to the control mainboard through terminal equipment such as an APP of a mobile phone, so that the electromagnet 121 is electrified to generate magnetism, and then the electromagnet 121 adsorbs the magnetic core 122; then, the driving member 131 is driven, and the first biasing force and the second biasing force are overcome, so that the lock tongue 11 is lifted through the lever principle, the lock tongue 11 and the hook buckle are in a separated state, at this time, the third biasing member 23 on the rod body 22 drives the rod body 22 to move towards the direction away from the shell 4, so that the hook buckle 21 is pushed to be separated, and the cabinet door is opened immediately. In the above process, the second detection end of the second in-place detection component 32 is triggered, and then the background detects the trigger signal that the second detection end is triggered, and meanwhile, the background also detects that the first in-place detection component 31 has no trigger signal, which indicates that the cabinet door is opened and the unlocking is successful. At this time, the first biasing member 132 and the second biasing member 14 are both in a resiliently compressed state.

After the unlocking is successful, the electromagnet can be powered off through the control main board, at the moment, the magnetism of the electromagnet disappears, the suction force between the magnetic core and the electromagnet disappears, and the transmission piece rotates under the combined action of the first biasing force and the first gravity moment; because the first gravity moment of the lock tongue 11 relative to the rotation fulcrum O is greater than the second gravity moment of the driving mechanism relative to the rotation fulcrum O, the lock tongue 11 is moved toward the locking position. Then, the door is closed, the catch 21 moves towards the direction close to the latch bolt 11, when the catch 21 is inserted, the latch bolt 11 will push the latch bolt 11 back to the closed state under the bias of the second biasing member 14 when the catch 21 is fully inserted, guided by the slope of the latch bolt 11. In the process that the hanging buckle 21 is inserted into the lock tongue 11, the rod body 22 is pushed to move towards the direction close to the shell 4, when the rod body 22 abuts against the first in-place detection assembly 31 and closes the first in-place detection assembly 31, the background detects that the first in-place detection assembly 31 is triggered, and the second in-place detection assembly 32 is not triggered, so that the cabinet door can be fed back to be in a locking state at the moment. At this point, the second biasing member 14 is still in compression, thereby holding the bolt 11 in the locked position.

In a dangerous situation, for example, when the opening and closing cabinet is a battery cabinet, the first biasing member 132, the second biasing member 14 and the third biasing member 23 may be disabled in case of an ultra-high temperature such as fire. At this time, because the first gravity moment of the lock tongue 11 relative to the rotation fulcrum O is greater than the second gravity moment of the driving mechanism relative to the rotation fulcrum O, the lock tongue can be kept at the locking position under the action of self gravity, so that the opening and closing cabinet is in the locking state, and the danger is prevented from spreading to other places.

In addition, when the lock device has a special fault or cannot power on the electromagnet 121, the fault driving end 111 can be pulled outwards to separate the lock bolt 11 from the hanging buckle 21, so that manual unlocking is realized.

The tool to lock device that this embodiment provided, wherein, actuation spare and driving piece magnetic force are connected, can be through the actuation and the separation of control actuation spare and driving piece to the driving medium that drives and the driving piece is connected rotates around rotating the fulcrum, and then realizes that the driving piece drives 11 motion realization unblanks and the action of shutting of spring bolt. The lockset device has simple structure and good locking effect. The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
