Description

Technical Field

[0001] This utility model relates to the field of locking mechanisms, and more specifically, to a multi-station locking mechanism. Background Technology

[0002] Currently, there is no additional locking mechanism on the handles or electrical switches of switch cabinets on the market. When the switch cabinet or line needs maintenance, the maintenance personnel will turn off the electrical switch of the switch cabinet or line, hang up the sign, and then begin the maintenance.

[0003] However, if unauthorized personnel enter the construction area and close the switch cabinet or electrical switch, it may result in electric shock to maintenance personnel or even mass casualties, seriously threatening people's lives and property.

[0004] To address the aforementioned issues, some interlocking mechanisms to prevent accidental operation have emerged on the market. However, these mechanisms simply involve placing an interlocking cover over the outside of the switch cabinet or electrical switch and then locking it with a padlock. Such interlocking mechanisms are complex to operate, and the warning signs cannot automatically switch according to the installation status of the interlocking mechanism. Furthermore, the suspended signs are prone to falling off.

[0005] Therefore, it is necessary to propose a multi-station interlocking mechanism to solve the above problems. Utility Model Content

[0006] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a multi-station locking mechanism.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a multi-station locking mechanism, including a lock body assembly and a locking cover installed on the switch cabinet handle or electrical switch;

[0008] The locking cover is provided with two or more locking positions, a status display panel with operating status indicators, and a communication port for the extension of switch cabinet handles or electrical switches.

[0009] The locking cover is connected to the lock body assembly via a locking station;

[0010] The status display panel is equipped with a stop sign, and one side of the stop sign has a notch or display area. The stop sign rotates to the corresponding position on the status display panel based on its own weight, according to the locking position connected to the lock body assembly. This allows the notch or display area of ​​the stop sign to show the working status of the switch cabinet handle or electrical switch in that locking position. Because the locking cover is placed over the switch cabinet handle or electrical switch, it prevents unauthorized personnel from turning the switch cabinet handle or electrical switch without unlocking it, reducing the occurrence of misoperation. Since the locking cover has two or more locking positions, construction personnel can adjust the installation direction of the locking cover according to the position of the switch cabinet handle or electrical switch. If the locking cover is installed incorrectly, the switch cabinet handle or electrical switch cannot extend from the connection port, making installation impossible. When the locking cover is correctly installed, the stop sign, being lighter on the notch or display area side, will rotate under its own weight, thus automatically switching the warning sign and preventing the status display panel and stop sign from falling off during construction.

[0011] Furthermore, the lock body assembly includes a lock body mounting base, a locking pin, an NFC antenna, passive magnetic induction components, and an MCU controller disposed within the lock body mounting base;

[0012] One end of the MCU controller is connected to a passive magnetic induction device, and the other end is connected to an NFC antenna;

[0013] The locking station is equipped with magnetic elements and locking holes;

[0014] When the lock body mounting base and the locking position are engaged with each other, the passive magnetic induction element in the lock body mounting base and the magnetic element in the locking position will mutually induct each other.

[0015] The locking pin is retractably mounted on the lock body mounting base. When the locking pin extends, it is inserted into the locking hole of the locking position. Since a passive magnetic induction element is set on the lock body mounting base and a magnetic element is set on the locking position, after the locking cover is installed, the magnetic element on the locking position will sense each other with the passive magnetic induction element in the lock body mounting base. The MCU controller in the lock body mounting base will determine the position of the switch cabinet handle or electrical switch based on the position of the passive magnetic induction element sensed by the magnetic element, and transmit the current status of the electrical switch and locking cover to the outside through the NFC antenna. In this utility model, the model of the MCU controller is CH444G.

[0016] Furthermore, it also includes conversion components, springs, and lock cylinders with keyholes;

[0017] The locking pin is provided with a slot, and the locking pin is set on the lock body mounting base by a spring;

[0018] The adapter has a "D"-shaped end, and its head is connected to the lock cylinder. The adapter's end is rotatably engaged in the locking pin's slot. The lock cylinder is connected to an MCU controller. When authorized, a person can insert a key into the keyhole to turn the lock cylinder. Since the adapter is connected to the lock cylinder, it will also rotate with the lock cylinder. Because the adapter's end is "D"-shaped, when the straight side of the "D" shape abuts against the edge of the locking pin's slot, the locking pin extends out of the lock body assembly under the action of a spring and inserts into the locking hole to lock the locking cover. When the adapter rotates 90 degrees, the intersection of the straight and curved sides of the "D"-shaped structure at the adapter's end abuts against the edge of the locking pin's slot, and the locking pin exits the locking hole, separating the lock body assembly from the locking cover. Since the lock cylinder is connected to the MCU controller, the MCU controller can also control the locking pin, thereby achieving remote control of the locking pin's unlocking or locking.

[0019] Furthermore, the passive magnetic induction element is a reed switch or a proximity switch, and the magnetic element is a magnet. When the passive magnetic induction element is a reed switch, when the magnetic element approaches the reed switch, the two reeds of the reed switch are magnetized, thereby generating magnetic fields of different polarities. When the magnetic element is attached to the reed switch, the two reeds will attract each other, thus achieving conduction. When the magnetic element is separated from the reed switch, the two reeds gradually demagnetize and disconnect, thus achieving disconnection. When the passive magnetic induction element is a proximity switch, if the magnetic element is attached to the proximity switch, the proximity switch can detect the proximity of the magnetic element and trigger the proximity switch to open. When the magnetic element is separated from the proximity switch, the proximity switch closes. In practical applications, the passive magnetic induction element and the magnetic element can also be replaced by other similar devices, all of which are within the protection scope of this utility model.

[0020] Furthermore, the passive magnetic induction device includes a first passive magnetic induction device and a second passive magnetic induction device.

[0021] The first passive magnetic induction element and the second passive magnetic induction element are respectively set at the upper and lower ends of the lock body mounting base. Since the first passive magnetic induction element and the second passive magnetic induction element are respectively set at the upper and lower ends of the lock body mounting base, the magnetic elements on the locking position can be connected in different directions. Based on the triggering of the first passive magnetic induction element and / or the second passive magnetic induction element, people can accurately determine the position of the switch cabinet handle or electrical switch.

[0022] Furthermore, the locking station includes a first locking station, a second locking station, and a third locking station;

[0023] The magnetic elements are respectively set at the bottom of the first locking position, the top of the second locking position, and the top and bottom of the third locking position. Since the magnetic elements are set in different positions in the first, second, and third locking positions, when different locking positions are connected to the lock body mounting base, people can accurately know the current state of the switch cabinet handle or electrical switch through the signal transmitted by the passive magnetic induction element on the lock body mounting base.

[0024] Furthermore, the locking station is provided with a locking station installation limiting groove, and the lock body mounting base is provided with a lock body limiting slide groove. The lock body mounting base is engaged with the locking station installation limiting groove of the locking station through the lock body limiting slide groove. By providing a locking station installation limiting groove on the locking cover and a lock body limiting slide groove on the lock body mounting base that matches the locking station installation limiting groove, the locking cover can be precisely positioned and installed with the lock body mounting base.

[0025] Furthermore, it also includes a rotating shaft. The barrier is rotatably mounted on the status display panel via the rotating shaft. With the rotating shaft, the barrier can rotate on the status display panel, thereby blocking the warning signs that do not correspond to those on the status display panel, while the corresponding warning signs are displayed in the notch or display area of ​​the barrier.

[0026] Furthermore, it also includes a protective cover with mounting slots;

[0027] The status display panel is provided with a mounting slot;

[0028] The protective cover is secured to the mounting slot of the status display panel via a mounting clip. By providing a mounting clip on the protective cover and a mounting slot on the status display panel, the protective cover can be quickly and easily installed on the status display panel.

[0029] Furthermore, the locking cover, status display panel, stop sign, and lock body mounting base are all made of plastic material. The locking cover, status display panel, stop sign, and lock body mounting base made of plastic material are simple and lightweight, reducing the production cost. Of course, in practical applications, the locking cover, status display panel, stop sign, and lock body mounting base can also be made of other materials, which are all easily conceived by those skilled in the art.

[0030] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0031] This utility model discloses a multi-position interlocking mechanism. The barrier, by its own weight, rotates to the corresponding position on the status display panel, thus displaying the working status of the switchgear handle or electrical switch in that interlocking position on the status display panel through the notch or display area of ​​the barrier. Because the interlocking cover is placed over the switchgear handle or electrical switch, it prevents unauthorized personnel from turning the switchgear handle or electrical switch without unlocking, reducing the occurrence of misoperation. Since the interlocking cover has two or more interlocking positions, construction personnel can adjust the installation direction of the interlocking cover according to the position of the switchgear handle or electrical switch. If the interlocking cover is installed incorrectly, the switchgear handle or electrical switch cannot extend from the connection port, making installation impossible. When the interlocking cover is correctly installed, the barrier, being lighter on the notch or display area side, will rotate under its own weight, thus automatically switching warning signs and preventing the status display panel and barrier from falling off during construction.

Detailed Implementation

[0050] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0052] like Figure 1-4 As shown, a multi-position locking mechanism includes a lock body assembly 1 and a locking cover 3 covering a switch cabinet handle or electrical switch 2. The locking cover 3 has two or more locking positions 4, a status display panel 5 with operating status indicators, and a communication port 6 for the switch cabinet handle or electrical switch 2 to extend out. The locking cover 3 is connected to the lock body assembly 1 through the locking positions 4. The status display panel 5 has a stop plate 7, and one side of the stop plate 7 has a notch 8 or a display area. The stop plate 7 rotates to the corresponding position on the status display panel 5 according to the locking position 4 connected to the lock body assembly 1 by its own weight, so that the notch 8 or display area of ​​the stop plate 7 displays the working status of the status display panel 5 in the current locking position 4 of the switch cabinet handle or electrical switch 2. The locking cover 3 is installed on the switch cabinet handle or electrical switch 2. Therefore, the locking cover 3 can prevent unauthorized personnel from turning the switch cabinet handle or electrical switch 2 without unlocking it, reducing the occurrence of misoperation. Since there are two or more locking positions 4 on the locking cover 3, the construction personnel can adjust the installation direction of the locking cover 3 according to the position of the switch cabinet handle or electrical switch 2. When the locking cover 3 is installed in the wrong direction, the switch cabinet handle or electrical switch 2 can no longer extend from the connection port 6, and it is impossible to install it. When the locking cover 3 is installed correctly, since the barrier 7 is lighter on the side of the notch 8 or the display area, the barrier 7 will rotate under its own weight, thereby realizing automatic switching of warning signs, and the status display panel 5 and barrier 7 will not fall off during the construction process.

[0053] like Figure 5-8As shown, the lock body assembly 1 includes a lock body mounting base 9, a locking pin 10, an NFC antenna 11, a passive magnetic induction element 12, and an MCU controller 13 disposed within the lock body mounting base 9. One end of the MCU controller 13 is connected to the passive magnetic induction element 12, and the other end is connected to the NFC antenna 11. The locking station 4 is provided with a magnetic element 14 and a locking hole 15. When the lock body mounting base 9 and the locking station 4 are engaged, the passive magnetic induction element 12 in the lock body mounting base 9 and the magnetic element 14 in the locking station 4 sense each other. The locking pin 10 is retractably disposed on the lock body mounting base 9. When the locking pin 10 extends, it inserts into the locking hole. In the locking hole 15 of position 4, since a passive magnetic induction element 12 is provided on the lock body mounting base 9 and a magnetic element 14 is provided on the locking position 4, after the locking cover 3 is installed, the magnetic element 14 on the locking position 4 will sense each other with the passive magnetic induction element 12 in the lock body mounting base 9. The MCU controller 13 in the lock body mounting base 9 will determine the position of the switch cabinet handle or electrical switch 2 according to the position of the passive magnetic induction element 12 sensed by the magnetic element 14, and transmit the current status of the electrical switch 2 and the locking cover 3 to the outside through the NFC antenna 11. In this utility model, the model of the MCU controller 13 is CH444G.

[0054] like Figure 9-13 As shown, it also includes a converter 16, a spring 17, and a lock cylinder 19 with a keyhole 18; the locking pin 10 has a slot 20, and the locking pin 10 is mounted on the lock body mounting base 9 via the spring 17; the end of the converter 16 is D-shaped, the head of the converter 16 is connected to the lock cylinder 19, and the end of the converter 16 is rotatably locked in the slot 20 of the locking pin 10. The lock cylinder 19 is connected to the MCU controller 13. When authorized, a person can rotate the lock cylinder 19 by inserting a key into the keyhole 18. Since the converter 16 is connected to the lock cylinder 19, the converter 16 will also rotate along with the lock cylinder 19. When the straight side of the "D" shape abuts against the edge of the groove 20 of the locking pin 10, the locking pin 10 extends out of the lock body assembly 1 under the action of the spring 17 and inserts into the locking hole 15 to lock the locking cover 3. When the conversion component 16 rotates 90 degrees, the intersection of the straight side and the arc side of the "D" shape at the end of the conversion component 16 abuts against the edge of the groove 20 of the locking pin 10, and the locking pin 10 exits the locking hole 15 to separate the lock body assembly 1 from the locking cover 3. Since the lock cylinder 19 is connected to the MCU controller 13, the MCU controller 13 can also control the locking pin 10, thereby realizing remote control of the locking pin 10 to unlock or lock.

[0055] In this invention, the passive magnetic induction element 12 is a reed switch or a proximity switch, and the magnetic element 14 is a magnet. When the passive magnetic induction element 12 is a reed switch, when the magnetic element 14 approaches the reed switch, the two reeds of the reed switch are magnetized, thereby generating magnetic fields of different polarities. When the magnetic element 14 is attached to the reed switch, the two reeds will attract each other, thus achieving conduction. When the magnetic element 14 is separated from the reed switch, the two reeds gradually demagnetize and disconnect, thus achieving disconnection. When the passive magnetic induction element 12 is a proximity switch, if the magnetic element 14 is attached to the proximity switch, the proximity switch can detect the approach of the magnetic element 14 and trigger the proximity switch to open. When the magnetic element 14 is separated from the proximity switch, the proximity switch closes. In practical applications, the passive magnetic induction element 12 and the magnetic element 14 can also be replaced by other similar devices, all of which are within the protection scope of this invention.

[0056] The passive magnetic induction element 12 includes a first passive magnetic induction element 21 and a second passive magnetic induction element 22. The first passive magnetic induction element 21 and the second passive magnetic induction element 22 are respectively disposed at the upper and lower ends of the lock body mounting base 9. Because the first passive magnetic induction element 21 and the second passive magnetic induction element 22 are respectively disposed at the upper and lower ends of the lock body mounting base 9, the magnetic element 14 on the locking position 4 can be connected in different directions. Based on the triggering of the first passive magnetic induction element 21 and / or the second passive magnetic induction element 22, the position of the switch cabinet handle or electrical switch 2 can be accurately determined. In this utility model, the locking station 4 includes a first locking station 23, a second locking station 24, and a third locking station 25; magnetic elements 14 are respectively disposed at the bottom of the first locking station 23, the top of the second locking station 24, and the top and bottom of the third locking station 25. Since the magnetic elements 14 are disposed in different positions in the first locking station 23, the second locking station 24, and the third locking station 25, when different locking stations 4 are used to connect with the lock body mounting base 9, people can accurately know the current state of the switch cabinet handle or electrical switch 2 through the signal transmitted by the passive magnetic induction element 12 on the lock body mounting base 9.

[0057] like Figure 14-17As shown, the locking station 4 is provided with a locking station installation limiting groove 26, and the lock body mounting base 9 is provided with a lock body limiting slide groove 27. The lock body mounting base 9 is engaged with the locking station installation limiting groove 26 of the locking station 4 through the lock body limiting slide groove 27. By providing a locking station installation limiting groove 26 on the locking cover 3 and a lock body limiting slide groove 27 on the lock body mounting base 9 that matches the locking station installation limiting groove 26, the locking cover 3 can be precisely positioned and installed with the lock body mounting base 9. In addition, it also includes a rotating shaft 28. The stop 7 is rotatably mounted on the status display panel 5 through the rotating shaft 28. With the setting of the rotating shaft 28, the stop 7 can rotate on the status display panel 5, thereby blocking the warning signs that do not correspond on the status display panel 5, while the corresponding warning signs are displayed in the notch 8 or display area of ​​the stop 7. In this utility model, a protective cover 30 with a mounting slot 29 is also included; a mounting slot 31 is provided on the status display panel 5; the protective cover 30 is secured to the mounting slot 31 of the status display panel 5 by the mounting slot 29. By providing the mounting slot 29 on the protective cover 30 and the mounting slot 31 on the status display panel 5, the protective cover 30 can be quickly installed on the status display panel 5. In this utility model, the locking cover 3, the status display panel 5, the stop plate 7, and the lock body mounting base 9 are all made of plastic material. The locking cover 3, the status display panel 5, the stop plate 7, and the lock body mounting base 9 made of plastic material are simple and lightweight, reducing the production cost. Of course, in practical applications, the locking cover 3, the status display panel 5, the stop plate 7, and the lock body mounting base 9 can also be made of other materials, which are all easily conceived by those skilled in the art.

[0058] Example

[0059] In this embodiment, during use, maintenance personnel place the interlock cover on the switch cabinet handle or electrical switch. Therefore, the interlock cover can prevent unauthorized personnel from turning the switch cabinet handle or electrical switch without unlocking, reducing the occurrence of misoperation. Since there are three interlocking positions on the interlock cover, the construction personnel can adjust the installation direction of the interlock cover according to the position of the switch cabinet handle or electrical switch. When the interlock cover is installed in the wrong direction, the switch cabinet handle or electrical switch can no longer extend from the connection port, and it is impossible to install it. When the interlock cover is correctly installed, since the barrier is lighter on the side of the notch or display area, the barrier will rotate under its own weight, thereby realizing automatic switching of warning signs, and the status display panel and barrier will not fall off during construction.

[0060] When the first locking station is connected to the lock body mounting base, the magnet in the first locking station is connected to the second passive magnetic induction element of the lock body mounting base. When the second locking station is connected to the lock body mounting base, the magnet in the second locking station is connected to the first passive magnetic induction element of the lock body mounting base. When the third locking station is connected to the lock body mounting base, the magnet in the third locking station is connected to the first passive magnetic induction element and the second passive magnetic induction element of the lock body mounting base respectively. Therefore, the current working state of the switch cabinet handle or electrical switch in the locking station can be determined by the triggering status of the first passive magnetic induction element and the second passive magnetic induction element.

[0061] When authorized, people can turn the lock cylinder by inserting a key into the keyhole. Since the adapter is connected to the lock cylinder, it will also rotate along with the lock cylinder. Because the end of the adapter is "D"-shaped, when the straight side of the "D" shape abuts against the edge of the locking pin's groove, the locking pin extends out of the lock body assembly under the action of the spring and inserts into the locking hole to lock the locking cover. When the adapter rotates 90 degrees, the intersection of the straight side and the curved side of the "D"-shaped structure at the end of the adapter abuts against the edge of the locking pin's groove, and the locking pin exits the locking hole, separating the lock body assembly from the locking cover. Since the lock cylinder is connected to the MCU controller, the MCU controller can also control the locking pin, thereby realizing remote control of the locking pin to unlock or lock.

[0062] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
