Further, the dial sleeve 13-9 of the present embodiment is of a cam structure, and a first microswitch 13-10 is disposed in the unlocking module 13. The first microswitch 13-10 of the embodiment is arranged on the outer wall (rear cover plate) of the locking plate sliding groove 13-2 b. The first microswitch 13-10 is used as a motor action inductor and has the function of collecting the rotation state of the dial sleeve 13-9 (a motor output shaft). The first micro switches 13-10 are connected to the controller 3 so as to transmit the rotation information of the dial sleeve to the controller 3. When the motor 13-6 drives the dial sleeve 13-9 to rotate for one circle, the state of the first microswitch 13-10 is changed, and the state of the first microswitch 13-10 is changed from closed state to open state, the dial sleeve 13-9 rotates for one circle, namely the eccentric column 13-9a returns to the initial position after being unlocked. The controller 3 controls the motor to rotate for one circle each time when the motor is unlocked by acquiring the state change of the first microswitch 13-10.

A locking plate reset spring 13-7 is arranged between the locking plate 13-5 and the locking plate sliding groove 13-2a (the rear cover plate 13-2), and the locking plate reset spring 13-7 provides a force for the locking plate 13-5 to move to the position which is abutted against the limiting part 13-3a on the lock bolt 13-3. In the embodiment, the locking plate 13-5 is provided with a spring groove for accommodating the locking plate return spring 13-7, the locking plate return spring 13-7 is arranged in the spring groove, one end of the locking plate return spring abuts against the inner wall of the spring groove, and the other end of the locking plate return spring abuts against the locking plate sliding groove 13-2 a.

The lock core linkage plate 13-8a is provided with an assembly hole 13-8a (figure 4), the lock core 12 is connected with the lock core linkage plate 13-8 through the matching between an eccentric column 12a arranged on the rear end part of the lock core and the assembly hole 13-8a, and the eccentric column 12a extends into the assembly hole 13-8a on the lock core pull rod 13-8. After the lock cylinder 12 is unlocked, the lock cylinder 12 is operated to rotate through a key, and the lock cylinder linkage plate 13-8 further drives the lock plate 13-5 to rotate, so that unlocking is realized.

As shown in FIG. 7, in the normal locking state, the upper part of the lock bolt 13-3 passes through the locking ring 2, and one end of the locking plate 13-5 extends into the limiting part 13-3a of the lock bolt 13-3, so as to clamp the lock bolt 13-3, so that the lock bolt cannot move downwards, and the cabinet door cannot be opened. As shown in figure 8, when unlocking, the locking piece 13-5 exits the limiting part 13-3a of the locking bolt 13-3, the locking bolt 13-3 is separated from the limiting part of the locking piece 13-5, and the locking bolt 13-3 is moved downwards under the action of the locking bolt spring 13-4 to be separated from the locking ring 2, so that the cabinet door can be opened.

Further, the unlocking module 13 further includes a second micro switch 13-11 (fig. 7), and the second micro switch 13-11 is disposed at an end of the latch 13-3 for sensing a position of the latch 13-3, so that a state of the door lock (i.e., a lock state detecting means) can be detected. The second microswitch 13-11 is connected to the controller 3 so as to send the position information of the latch 13-3 to the controller 3. In order to avoid the latch 13-3 from frequently contacting with the second microswitch 13-11 and causing the second microswitch 13-11 to be damaged, preferably, an elastic sheet 13-12 is arranged between the latch 13-3 and the second microswitch 13-11, and the end part of the latch 13-3 contacts with the second microswitch 13-11 through the elastic sheet 13-12. The impact on the first microswitch 13-10 is smaller than that on the second microswitch 13-11, and a protective elastic sheet is not needed. The motor action sensor (13-10) and the lock bolt position sensor (13-11) can adopt sensors such as a Hall device, a proximity sensor and the like besides a microswitch.

As shown in fig. 9, the controller 3 is connected to the remote lock control system host 4 through the wireless communication module, and performs information interaction with the lock control system host 4 through the wireless network, so as to send the state of the lock plunger sensed by the second micro switch to the lock control system host 4, so that the remote management center can obtain the state of the door lock in time. The lock control system host 4 is a conventional remote management platform, and the lock control system host 4 is preset with general microcomputer anti-misoperation system software in the prior art and is used for management, authorization and other operations of locks. The lock control system host 4 can send an instruction to the controller 3 to unlock the door lock. More preferably, in order to reduce the power consumption of the system, the cabinet door lock further includes a wake-up button 5, the wake-up button 5 is disposed on the outer shell 11, and the wake-up button 5 is electrically connected to the controller 3. In a normal state, the controller 3 is in a dormant state, when unlocking is needed, the awakening button 5 is pressed down first, the controller 3 is awakened from the dormant state, then the lock control system host 4 can send an unlocking signal to the controller 3, the controller 3 controls the motors 13-6 to act according to the unlocking signal sent by the lock control system host 4, and unlocking is carried out, and in the unlocking process, the rotation state of the motors sensed by the first micro switch can be convenient for controlling the rotation stroke of the motors; the second micro-switches 13-11 collect the state of the door lock (lock bolt) and send the collected information to the controller 3, and the controller 3 uploads the current state information of the door lock to the lock control system host 4. When the door lock is in the awakening state, the lock control system host 4 can request the controller 3 to upload the current state of the door lock at any time. The wake-up button 5 is arranged to further have an effect of confirming that the operator is in place, for example, the controller 3 is in a dormant state in a normal state, the controller 3 cannot receive an unlocking signal to unlock in the dormant state, the unlocking signal can be sent to the controller 3 to unlock only after the operator presses the wake-up button 5 to wake-up the controller 3 on site, and the unlocking signal cannot be sent to the controller to unlock if the operator is not in place. In addition, in order to enable the lock control system host 4 to periodically check the status of the cabinet door lock, the controller 3 may be configured to periodically and automatically wake up (i.e., may automatically wake up without pressing a wake-up button), and the current status of the cabinet door lock is actively uploaded to the lock control system 4 after the controller 3 automatically wakes up. The period of automatic wake-up may be 24 hours or 12 hours or 8 hours, or other times.

As shown in fig. 11, the lock control system includes an electric control lock (cabinet door lock), a controller 3, and a lock control system host 4, and the lock control system host 4 is connected to the controller 3 in a remote communication manner. The electric control lock is internally provided with a driving unit (a motor), a lock state detection device (a second microswitch) and a driving unit action inductor (a first microswitch) which are electrically connected with the controller 3.

The door lock of the invention has two unlocking channels: the motor unlocking channel and the lock cylinder unlocking channel. These two unlocking methods will be described below with reference to fig. 7 and 8.

Unlocking a channel by the motor: as shown in fig. 7, when locking, the locking plate 13-5 extends into the limiting part 13-3a of the locking bolt 13-3, the locking bolt 13-3 cannot move, and the upper part of the locking bolt passes through the locking ring 2 to realize locking; when the controller is in an awakening state, when the lock control system host 4 sends an unlocking signal to the controller 3 through a network, after the controller 3 receives the unlocking signal, the motor 13-6 is controlled to rotate, the motor 13-6 drives the dial sleeve 13-9 to rotate for a circle, the eccentric shaft 13-9a at the end part of the dial sleeve 13-9 drives the lock plate 13-5 to move, the lock plate 13-5 leaves the limiting part 13-3a of the lock bolt 13-3, and after the lock bolt 13-3 leaves the limiting part of the lock plate 13-5, the lock bolt moves downwards under the action of the lock bolt spring 13-4 to separate from the lock ring 2, so that unlocking is realized (figure 8). In the unlocking process, the controller 3 collects the rotation information of the motor through the first micro switches 13-10, so that the motor is controlled to rotate for one circle each time the motor is unlocked. When locking, the lock bolt 13-3 is pushed upwards, the upper part of the lock bolt passes through the lock ring 2, and the lock plate 13-5 extends into the limiting part 13-3a of the lock bolt 13-3 again under the action of the lock plate return spring 13-7 to limit the lock bolt 13-3, so that locking is realized.

In addition, the unlocking signal can be sent to the controller 3 through the mobile terminal 6 to perform unlocking operation. As shown in fig. 10, the mobile terminal 6 obtains an unlocking authorization from the lock control system host 4, and sends an unlocking signal to the controller 3 through bluetooth, and the controller 3 controls the motor 13-6 to act for unlocking. The door lock state information collected by the second micro switches 13-11 can be directly sent to the lock control system host 4 through the controller 3, and under the condition of bad network, the door lock state information can also be sent to the mobile terminal 6 through the controller 3, and then sent to the lock control system host 4 through the mobile terminal 6. The mobile terminal 6 may also perform unlocking by directly issuing an unlocking instruction to the controller 3 by the lock control system host 4 after requesting unlocking from the lock control system host 4.

A lock cylinder unlocking channel: as shown in fig. 11, the door lock can be opened by using an authorized computer key 7, and a code reading circuit is arranged on the unlocking head of the computer key 7, so that the code of the ID code chip at the front end of the lock cylinder 13 can be read. The computer key 7 is connected with the lock control system host 4 through the mobile terminal 6 or a key adapter (not shown), and obtains unlocking authority from the lock control system host 4. The computer key 7 reads the code of the ID code chip of the door lock, and the door lock can be unlocked only after the lock is confirmed to be the door lock which is authorized to be opened. After unlocking, the computer key 7 is used for operating the rotating lock cylinder 12, and when the lock cylinder 12 rotates, the lock cylinder linkage plate 13-8 is driven to move, so that the lock plate 13-5 is pulled to rotate, and unlocking is realized. A plurality of case cabinet doors can use the same lock core, and every lock core front end is equipped with the ID chip of different codes, and the lock core is inserted to computer key 7's unblock head, reads the code of ID chip, confirms that ID code is correct after, and unblock head can rotate the lock core, can manage a plurality of tool to lock through a computer key 7 like this, has avoided that a key corresponds the mode of a lock and leads to the chaotic condition of many keys management among the prior art.

In addition, can also set up the door state sensor who is connected with the controller electricity on the cabinet door for the state of response cabinet door, so that managers combines lock state detection device to judge lock state and cabinet door state better, prevent to take place because of the incident that lock or door do not correctly close and lead to. The door state sensor of the present embodiment may employ a door state sensor that is conventional in the art.

This example differs from example 1 in that: the unlatching module 13 of this embodiment also includes a latching stop 13-13, the latching stop 13-13 being located in the latching ring groove 13-2a opposite the latching ring. As shown in fig. 12 and 13, the latch stop 13-13 includes a stop mount 13-13a, a stop 13-13b, and a stop spring 13-13 c. The stopper 13-13b of the embodiment is arranged in the stopper mounting seat 13-13a, the stopper mounting seat 13-13a is arranged in the lock ring groove 13-2a, the stopper spring 13-13c is arranged between the stopper 13-13b and the stopper mounting seat 13-13a, the stopper 13-13b is popped out of the stopper mounting seat 13-13a under the action of the stopper spring 13-13c, and the stopper 13-13b is positioned on the moving path of the lock bolt 13-3 after being popped out; the stopper 13-13b is retracted into the stopper mount 13-13a against the elastic force of the stopper spring 13-13c when an external force is applied.

The operation of the tumbler lock is further described below with reference to fig. 14 and 15:

as shown in fig. 14, when locking, the lock ring 2 extends into the lock body (lock ring groove), the lock bolts 13-13 pass through the lock ring 2, and the cabinet door cannot be opened. When the shackle 2 is in a locked position extending into the lock body, the forward end of the shackle 2 abuts the stop 13-13b of the bolt blocker 13-13, urging the stop 13-13b into the blocker mount 13-13 a.

As shown in fig. 15, when unlocking, the lock bolt 13-3 moves downward to withdraw the lock ring 2, so that the lock ring 2 can be withdrawn outward from the lock body, thereby opening the cabinet door. When the lock ring 2 is withdrawn from the lock body, the stop 13-13b is ejected outwards under the action of the stop spring 13-13c due to the loss of the abutting of the lock ring 2 and moves to the moving path of the lock bolt 13-3, and the lock bolt 13-3 cannot move upwards at the moment due to the blocking of the stop 13-13 b.

In the embodiment, the lock bolt blocking piece is arranged, if the door is not closed correctly, namely the lock ring 2 does not extend into the lock body, because no other external force acts on the stop blocks 13-13b, the stop blocks 13-13b are always positioned on the moving path of the lock bolt 13-3 under the action of the stop block springs 13-13c, the lock bolt 13-3 is blocked and cannot be locked upwards, and at the moment, the second microswitch 13-11 cannot sense the lock bolt 13-3, which indicates that the door is not closed and the door lock is not locked; when the door is correctly closed, the lock ring 2 extends into the lock body and pushes the stop block 13-13b of the lock bolt stop block 13-13 back into the stop block mounting seat 13-13a, the stop block 13-13b leaves the moving path of the lock bolt 13-3, the lock bolt 13-3 can move upwards at the moment, the lock is locked by penetrating through the lock ring 2, and the second microswitch 13-11 senses the lock bolt 13-3 at the moment, so that the condition that the door is closed and the door lock is locked is avoided, and the condition that the door is not correctly closed and the door lock is locked is avoided. In the embodiment, the lock bolt position sensor and the door state sensor are integrated, the detection of two states of the door lock state and the door closing state can be realized only by arranging one sensor (the second micro switch 13-11), the additional arrangement of the door state sensor is not needed, and the structure is simplified.

This example differs from example 2 in that: the stopper 13-13b of the plug stops of this embodiment is disposed in the latch groove 13-2a by the rotation shaft 13-13 d. As shown in fig. 17, the stopper 13-13b of this embodiment is a fan-shaped block body, the stopper 13-13b is rotatable about the rotation shaft 14-13d, and the stopper 13-13b is rotatable to be on the movement path of the latch 13-3 or to be away from the movement path of the latch 13-3 when rotated about the rotation shaft 13-13 d. The stop spring is a torsion spring (not shown), when the stop 13-13b is not acted by other external force, the torsion spring rotates the stop 13-13b to a position located on the moving path of the lock bolt 13-3, when the lock ring 2 is inserted after the door is closed, the front end of the lock ring 2 is abutted against the stop 13-13b, and as the lock ring 2 is continuously inserted, the stop 13-13b is jacked by the lock ring 2, so that the lock bolt 13-3 can upwards pass through the lock ring 2 to realize locking, and the lock bolt 13-3 can rotate out of the moving path of the lock bolt 13-3.

Example 4

This example differs from example 1 in that: the lock body of this embodiment does not set up the lock core in, does not have lock core interlock board in the unblocking module, does not possess lock core unblock passageway promptly, can only pass through the motor unblock. The unlocking and locking module comprises a front cover plate, a rear cover plate, a lock bolt spring, a lock plate, a motor, a lock plate return spring and a shifting sleeve, and the connection relation among the elements is the same as that of the embodiment 1.

In a locking state, the lock ring extends into the lock body, the upper part of the lock bolt penetrates through the lock bolt, the lock plate extends into the limiting part of the lock bolt, and the lock bolt cannot move to realize locking; the lock control system host sends an unlocking signal to the controller through the network, the controller controls the motor to rotate after receiving the unlocking signal, the motor drives the lock plate to move through the shifting sleeve, the lock plate leaves the limiting part of the lock bolt, and the lock bolt moves downwards under the action of the lock bolt spring after being separated from the limiting part of the lock bolt, so that the lock bolt is separated from the lock ring, and unlocking is realized.

When the lock is locked, the lock bolt is pushed upwards, the upper part of the lock bolt penetrates through the lock ring, and the lock plate stretches into the limiting part of the lock bolt again under the action of the lock plate reset spring to limit the lock bolt, so that locking is realized.

When the mobile terminal is adopted to send an unlocking signal to the controller for unlocking and locking, the mobile terminal obtains unlocking authorization from the lock control system host, and sends the unlocking signal to the controller through Bluetooth, and the controller controls the motor to act for unlocking. Or after the mobile terminal requests the lock control system host to unlock, the lock control system host directly issues an unlocking instruction to the controller to unlock.

Of course, the technical concept of the present invention is not limited to the above embodiments, and many different specific schemes can be obtained according to the concept of the present invention, for example, the lock ring may be in a U-shaped structure, or in a ring-shaped structure, or may be processed on a metal sheet body with certain strength in a lock hole manner; when the door is opened outwards, the lock ring is fixed with the cabinet body, the lock body is arranged on the door, when the door is opened inwards, the lock body can also be fixed with the cabinet body, and the lock ring is arranged on the door; the lock ring can extend into the lock body, and can also be positioned outside the lock body, such as independently arranged above or below the lock body, as long as the lock bolt can pass through the lock ring to realize locking; the shifting sleeve can also be a round block, and the rotating state of the shifting sleeve (the output shaft of the motor) is induced by arranging a magnetic proximity sensor to replace a first microswitch; such modifications and equivalents are intended to be included within the scope of the present invention.
