Description

Technical Field

[0001] This invention relates to the field of electronic lock technology, and in particular to a multifunctional electronic lock for a metering box. Background Technology

[0002] With the advancement of the information age and the improvement of product technology, the quality of equipment has significantly improved. To reduce daily consumable costs, improve corporate efficiency, and promote company development, the company encourages employees to innovate and modify equipment in terms of stability, miniaturization, high reliability, and safety. After on-site meter installation, the metering box needs to be sealed with a wire seal. Each time the box is opened, the seal needs to be cut, resulting in the loss of one seal each time, leading to high consumable costs over time. For large-scale upgrades or meter inspections, there may be issues such as insufficient seals, excessive weight due to too many seals, and difficulty in accurately locating the metering box. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a multi-functional electronic lock for a metering box.

[0004] The present invention adopts the following technical solution:

[0005] The metering box multi-functional electronic lock includes: electronic lock body, electronic lock body protective cover, rotary lock tongue, fixing platform, lock cylinder, power output component and anti-loosening component;

[0006] The rotating bolt and the electronic lock body protective cover rotate to connect. The rotating bolt (3) is rotated to the end of the electronic lock body (1) away from the fixed platform (4). The rotating bolt has two states: retracted locking and lowered unlocking. The fixed platform is rotated in the electronic lock body protective cover and is fixed to the inner wall of the metering box. The electronic lock body can rotate around the fixed platform. Multiple fixing holes are opened along the circumferential direction on the side wall of the fixed platform. The lock cylinder is slidably set inside the electronic lock body protective cover. The lock cylinder includes a guide post, which can slide into the fixing hole. A second motor is also provided on the outside of the electronic lock body to drive the electronic lock body to rotate. A third motor is provided on the outside of the electronic lock body to drive the rotating bolt to rotate.

[0007] According to the aforementioned multi-functional electronic lock for the metering box, the main protective cover of the electronic lock is also equipped with a power output component. The power output component drives the guide column to slide closer to or away from the fixed platform. The anti-loosening component is slidably connected to the main protective cover of the electronic lock. The anti-loosening component is repelled by the rotating lock tongue. When the rotating lock tongue is retracted and locked, the anti-loosening component restricts the lock cylinder from sliding toward the fixed platform. When the rotating lock tongue is lowered and unlocked, the anti-loosening component no longer restricts the lock cylinder from sliding toward the fixed platform.

[0008] According to the aforementioned multi-functional electronic lock for the metering box, the lock cylinder also includes: a sliding table, a translational component, a first compression spring, a second compression spring, and a first starter; the sliding table has a sliding area, the translational component is located within the sliding area, and can slide within the sliding table; one end of the guide post is inserted through one side of the sliding table and contacts one end of the translational component; one end of the first compression spring contacts the protective cover of the electronic lock body, and the other end of the first compression spring is located on the guide post; one end of the second compression spring contacts the translational component, and the other end of the second compression spring contacts the sliding table.

[0009] According to the multi-functional electronic lock of the metering box, a stop plate is fixed at the bottom of the sliding table, and a starter is set on the displacement path of the stop plate. After the sliding table moves toward the fixed table, the starter is activated through the stop plate.

[0010] A ratchet bar extends outward from the end of the sliding table away from the guide post. Multiple ratchet teeth are provided on the side of the sliding table adjacent to the ratchet bar, and the multiple ratchet teeth are arranged at equal intervals. A stop platform is provided at the end of the ratchet teeth close to the fixed table, and a ramp is provided at the end of the ratchet teeth away from the fixed table.

[0011] According to the aforementioned multi-functional electronic lock for the metering box, the power output component includes: a motor, a main ratchet, a connecting platform, a rotating column, and a compression spring. The connecting platform, the rotating column, and the main ratchet are coaxial. The rotating column is located between the connecting platform and the main ratchet, and the compression spring is sleeved on the rotating column. The main ratchet is located on the main shaft of the motor. The main ratchet meshes with the ratchet rack.

[0012] According to the multi-functional electronic lock of the metering box, the main ratchet includes: a ratchet disc 1 with ratchet teeth on the top and a ratchet disc 2 with ratchet teeth on the bottom, the ratchet disc 1 and the ratchet disc 2 are coaxial; the ratchet disc 1 is fixedly connected to the main shaft of the motor 1, the ratchet disc 2 is sleeved on the rotating column, the ratchet disc 2 is rotatably connected to the rotating column, and is in contact with the compression spring 3.

[0013] According to the aforementioned multi-functional electronic lock for the metering box, the anti-loosening component includes: a stop member, a pressing member, a sliding member one, a sliding member two, and a starter two; the stop member, the pressing member, the sliding member one, and the sliding member two are all slidably connected to the main body protective cover of the electronic lock, and the pressing member, the sliding member one, and the sliding member two are in sequential contact; the sliding member two is provided with a displacement space, the stop member is located in the displacement space and is slidably connected to the sliding member two, a compression spring is provided between the sliding member two and the main body protective cover of the electronic lock, a stop plate two is also provided on one end face of the sliding member two, and the starter two is located on the sliding path of the stop plate two.

[0014] According to the multi-functional electronic lock for the metering box, the rotating lock tongue is provided with an arched notch and an arched protrusion; when the rotating lock tongue is in the downward unlocking position, the pressing member contacts the lower end of the arched notch, causing the pressing member to slide toward the rotating lock tongue.

[0015] According to the aforementioned multi-functional electronic lock for the metering box, the rotating bolt further includes: a connector, which is slidably connected to the protective cover of the electronic lock body, and the connector is in contact with the rotating bolt; an arched notch two and an arched notch three are provided at the head where the rotating bolt is spun and connected to the protective cover of the electronic lock body; when the rotating bolt is in the retracted locking position, the connector is in contact with the inner wall of the arched notch two of the rotating bolt; when the rotating bolt is in the descending unlocking position, the connector is in contact with the inner wall of the arched notch three of the rotating bolt.

[0016] The bottom of the rotating latch is equipped with a hook head, which has anti-slip beads. The hook head can rotate along the longitudinal center line of the rotating latch.

[0017] The multi-functional electronic lock for the metering box also includes a processing unit and a communication unit, which are connected by wires. Both starter one and starter two are connected to the processing unit by wires.

Therefore, the stability and reliability of the locking are further improved.

[0022] 4. The electronic lock in the metering box can transmit information to mobile phones and other electronic devices. Therefore, mobile phones and other electronic devices can record the location of the metering box, thereby enabling accurate location of all metering boxes. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] according to Figures 1-10 As shown:

[0038] This invention provides a multifunctional electronic lock for a metering box, comprising: an electronic lock body 1, an electronic lock body protective cover 2, a rotary latch 3, a fixed platform 4, a lock cylinder 5, a power output component 6, and an anti-loosening component 7. The rotary latch 3 and the electronic lock body protective cover 2 are rotatably connected. The rotary latch (3) is rotatably connected to the end of the electronic lock body (1) away from the fixed platform (4). The rotary latch 3 has two states: retracted locking and lowered unlocking. The fixed platform 4 is rotatably disposed in the electronic lock body protective cover 2 and is fixedly connected to the inner wall of the metering box. The electronic lock body 1 can rotate around the fixed platform 4. The side wall of the fixed platform 4 has openings along the circumferential direction. Multiple fixing holes 42; the lock cylinder 5 is slidably disposed inside the electronic lock body protective cover 2, the lock cylinder 5 includes: a guide post 52, the guide post 52 can slide into the fixing holes 42; the electronic lock body protective cover 2 is also provided with a power output component 6, the power output component 6 drives the guide post 52 to slide closer to or away from the fixed platform 4; the anti-loosening component 7 is slidably connected to the electronic lock body 1 protective cover 2, the anti-loosening component 7 is repelled by the rotating lock tongue 3, the anti-loosening component 7 constrains the lock cylinder 5 to slide toward the fixed platform 4 when the rotating lock tongue 3 is retracted and locked, the anti-loosening component 7 no longer constrains the lock cylinder 5 to slide toward the fixed platform 4 when the rotating lock tongue 3 is lowered and unlocked. By placing the fixed platform 4 and the guide post 52 inside the electronic lock body protective cover 2, it can be ensured that the guide post 52 is not damaged and the electronic lock operates stably. Furthermore, by controlling the locking and unlocking of the electronic lock through the two states of rotating the bolt 3, it can be prevented that the electronic lock will be accidentally opened or closed due to accidents during operation, thereby improving the stability and reliability of the electronic lock during use.

[0039] according to Figure 1 and Figure 3 As shown:

[0040] The lock cylinder 5 also includes: a sliding table 53, a translational member 54, a first compression spring 55, a second compression spring 56, and a first actuator 57. The sliding table 53 has a sliding area 532. The translational member 54 is located within the sliding area 532 and can slide within the sliding table 53. One end of the guide post 52 extends through one side of the sliding table 53 and contacts one end of the translational member 54. One end of the first compression spring 55 contacts the electronic lock body protective cover 2, and the other end of the first compression spring 55 is located on the guide post 52, ensuring a certain distance between the electronic lock body protective cover 2 and the sliding table 53. One end of the second compression spring 56 contacts the translational member 54, and the other end of the second compression spring 56 contacts the sliding table 53. The guide post 52 translates radially along the fixed platform 4, ensuring that the guide post 52 can be stably inserted into the fixed hole 42, achieving a more secure locking connection.

[0041] When the sliding table 53 moves within the electronic lock body protective cover 2, it applies a compressive force to the compression spring 55, causing the guide post 52 to move as well. The second compression spring 56 ensures a certain distance between the translating member 54 and the sliding table 53. If misalignment occurs between the guide post 52 and the fixing hole 42, preventing the guide post 52 from sliding, the compression spring 56 can apply a compressive force to maintain the gap between the translating member 54 and the sliding table 53. The second compression spring 56 absorbs energy, allowing the sliding table 53 to achieve the purpose of mitigating the impact force.

[0042] Furthermore, when the guide post 52 moves toward the fixing hole 42, if the center lines of the guide post 52 and the fixing hole 42 coincide, the guide post 52 can be directly inserted into the fixing hole 42. The fixing platform 4, through the entry of the guide post 52, thus constrains the rotation of the electronic lock body 1. If misalignment occurs between the guide post 52 and the fixing hole 42, the head of the guide post 52 will abut against the outer wall of the fixing platform 4, preventing further movement of the guide post 52 toward the fixing platform 4. A second motor is also provided on the outside of the electronic lock body 1 to drive the electronic lock body 1 to achieve its rotation. When the electronic lock is working, the second motor drives the electronic lock body 1 to rotate until the guide post 52, under the restoring force of the first compression spring 55 and the second compression spring 56, moves and inserts into the fixing hole 42, thus achieving the first step of locking.

[0043] The compression spring 56 can prevent the power output component 6 from being unable to move due to the inability of the sliding table 53 to slide, which could eventually cause the power output component 6 to jam. A stop plate 535 is fixed at the bottom of the sliding table 53, and the starter 57 is located on the displacement path of the stop plate 535. After the sliding table 53 moves toward the fixed table 4, the starter 57 is activated via the stop plate 535.

[0044] according to Figure 3 and Figure 4 As shown:

[0045] A ratchet bar 533 extends outward from the end of the sliding table 53 away from the guide post 52. Multiple ratchet teeth 534 are provided on the side of the sliding table 53 adjacent to the ratchet bar 533, and the multiple ratchet teeth 534 are arranged at equal intervals. A stop platform 5342 is provided at the end of the ratchet tooth 534 near the fixed table 4, and a ramp 5343 is provided at the end of the ratchet tooth 534 away from the fixed table 4.

[0046] according to Figure 3 As shown:

[0047] The power output component 6 includes: a motor 62, a main ratchet 63, a connecting platform 64, a rotating column 65, and a compression spring 66. The connecting platform 64, the rotating column 65, and the main ratchet 63 are coaxial. The rotating column 65 is located between the connecting platform 64 and the main ratchet 63, and the compression spring 66 is sleeved on the rotating column 65. The main ratchet 63 is mounted on the main shaft of the motor 62. The main ratchet 63 meshes with a ratchet rack 533. The motor 62 drives the main ratchet 63 to rotate, which in turn drives the sliding platform 53 to slide via the ratchet rack 533, thereby achieving the purpose of sliding the guide column 52.

[0048] Furthermore, motor 62 can rotate in the forward direction or in the reverse direction. When motor 62 rotates in the forward direction, the sliding table 53 moves towards the fixed table 4 with the guide post 52 to perform the first locking action. When motor 62 rotates in the reverse direction, the sliding table 53 moves away from the fixed table 4 with the guide post 52 to perform the second unlocking action.

[0049] Furthermore, the main ratchet disc 63 includes: a first ratchet disc 632 with ratchet teeth at the top and a second ratchet disc 633 with ratchet teeth at the bottom, with the first ratchet disc 632 and the second ratchet disc 633 coaxial. The first ratchet disc 632 is fixed to the main shaft of the first motor 62, and the second ratchet disc 633 is sleeved on the rotating column 65, rotatingly connected to the rotating column 65 and in contact with the third compression spring 66. There is a certain distance between the second ratchet disc 633 and the connecting platform 64, which is greater than the overall height of the ratchet teeth on the second ratchet disc 633.

[0050] If the sliding table 53 malfunctions and becomes stuck, preventing it from moving, and the motor 62 drives the ratchet 632 to rotate, the ratchet 633 will not rotate under the meshing force because it is engaged with the ratchet rack 533. However, the upper surface of the ratchet 632 has a guiding function, which can drive the ratchet 633 to move away from it along the rotating post 65, thus allowing relative sliding between them and preventing the motor 62 from transmitting kinetic energy to it, thereby protecting the motor 62.

[0051] according to Figure 5 and Figure 6 As shown:

[0052] The anti-loosening component 7 includes: a stop member 72, a pressing member 73, a first sliding member 74, a second sliding member 75, and a second actuator 76. The stop member 72, pressing member 73, first sliding member 74, and second sliding member 75 are all slidably connected to the electronic lock main body protective cover 2, and the pressing member 73, first sliding member 74, and second sliding member 75 are in sequential contact. The second sliding member 75 has a displacement space 752, in which the stop member 72 is located and slidably connected. A compression spring is provided between the second sliding member 75 and the electronic lock main body protective cover 2, ensuring a certain distance between the second sliding member 75 and the sliding table 53. A second stop plate 753 is also provided on one end face of the second sliding member 75, and the second actuator 76 is located on the sliding path of the second stop plate 753.

[0053] The rotary latch 3 has an arched notch 322 and an arched protrusion 323. When the rotary latch 3 is in the downward unlocking position, the pressing member 73 contacts the lower end of the arched notch 322, causing the pressing member 73 to slide towards the rotary latch 3. Due to the setting of the compression spring, there is a certain distance between the stop member 72 and the ratchet 534, and the stop member 72 stops limiting the ratchet 534 and the sliding table 53.

[0054] according to Figure 5 , Figure 7 or Figure 10 As shown:

[0055] When the rotating locking tongue 3 retracts, it is in the retracted locking position, achieving the second locking step. The pressing member 73 contacts the arched protrusion 323, causing the pressing member 73 to slide away from the rotating locking tongue 3. Because the arched protrusion 323 protrudes outward relative to the arched notch 322, the sliding member 74 and the sliding member 75 push the stop member 72 toward the sliding table 53.

[0056] The rotary latch 3 also includes a connector 33, which is slidably connected to the electronic lock body protective cover 2 and contacts the rotary latch 3. The head of the rotary latch 3, where it is spun and connected to the electronic lock body protective cover 2, is provided with an arched notch 2 324 and an arched notch 325. When the rotary latch 3 is retracted and locked, the connector 33 contacts the inner wall of the arched notch 2 324 of the rotary latch 3. When the rotary latch 3 is lowered and unlocked, the connector 33 contacts the inner wall of the arched notch 325 of the rotary latch 3. Because the arched notches 324 and 325 are recessed inward, when the connector 33 contacts the inner wall of the arched notch 324 of the rotating bolt 3, and when the connector 33 contacts the inner wall of the arched notch 325, the connector 33 remains below the arched notches 324 and 325, thus ensuring the stability of the rotating bolt 3 in both the retracting locking and lowering unlocking states.

[0057] The electronic lock body has a motor 3 on the outside, which drives the rotating bolt 3 to rotate; the bottom of the rotating bolt 3 has a hook 34, which is used to further enhance the stability and reliability of the locking. The hook 34 has anti-slip beads and can rotate along the longitudinal center line of the rotating bolt 3.

[0058] according to Figure 8 and Figure 9 As shown:

[0059] The stop member 72 includes a second stop platform 722 and a second inclined platform 723. When the stop member 72 engages with the ratchet 534, the second stop platform 722 engages with the first stop platform 5342 and constrains the sliding platform 53 to slide toward the fixed platform 4. The second inclined platform 723 and the first inclined platform 5343 have a guiding function, allowing the sliding platform 53 to slide away from the fixed platform 4 when the stop member 72 slides within the second sliding member 75.

[0060] The electronic lock also includes a processing unit and a communication unit, which are connected by wires. Actuator 1 (57) and Actuator 2 (76) are both connected to the processing unit by wires. The communication unit interacts with electronic devices such as mobile phones, enabling these devices to send unlocking and locking commands to the electronic lock via signals. Upon receiving a command, the processing unit manages the cooperation of motors 1 (62), 2 (62), and 3 (76) to achieve the unlocking and locking results. First, motor 2 drives the electronic lock body to rotate. Second, after motor 1 (62) drives the sliding table 53 to slide towards the fixed table 4, the stop plate 535 contacts actuator 1 (57). Finally, motor 3 drives the rotating bolt 3 to rotate, thus completing the locking. The processing unit then receives the locking message and transmits it to the mobile phone or other electronic device via the communication unit.

[0061] Working principle:

[0062] By connecting the fixed platform 4 to the inner wall of the metering box, firstly, motor 2 drives the electronic lock body to rotate. Secondly, when motor 1 drives the guide post 52 to move towards the fixed platform 4, the guide post 52 can cooperate with the fixing hole 42 on the fixed platform 4, thereby constraining the rotation of the electronic lock body and achieving the first step of locking the electronic lock. Finally, motor 3 drives the rotating bolt 3 to rotate. When it rotates to the locking position, the second step of locking is achieved. Both the fixed platform 4 and the guide post 52 are located in the electronic lock body protective cover 2. The first step of locking and the second step of unlocking the electronic lock are both within the electronic lock body protective cover 2, which protects the guide post 52 from damage, enhancing the stability and reliability of the electronic lock. The sliding platform 53 and the translational member 54 that moves on the sliding platform 53 can reduce the impact force of the guide post 52 and protect motor 1 when the guide post 52 is not inserted into the fixing hole 42.

[0063] Work process:

[0064] S1. Send a locking command to the electronic lock via a mobile phone or other electronic device;

[0065] S1.1, The motor drives the electronic lock body to rotate;

[0066] S1.2, Motor 62 drives guide post 52 to move toward fixed platform 4, guide post 52 is inserted into fixed hole 42, completing the first step of locking;

[0067] S1.3 The motor drives the rotary locking tongue 3 to rotate to the locked position, completing the second step of locking;

[0068] S2. Send an unlocking command to the electronic lock via a mobile phone or other electronic device;

[0069] S2.1 The motor drives the rotary lock tongue 3 to rotate in the opposite direction, so that it rotates back to its original position, completing the first step of unlocking;

[0070] S2.2, Motor 62 rotates in the opposite direction, driving guide post 52 to move away from fixed platform 4, and guide post 52 is pulled out from fixed hole 42;

[0071] S2.3 The second motor drives the electronic lock body 1 to rotate, causing the guide post 52 to abut against the outer wall of the fixed platform 4, completing the second step of unlocking.

[0072] Therefore, by setting up a sliding table and a translational component that can move within the sliding table, the impact force of the guide column can be reduced, thus protecting the motor when the guide column is not inserted into the fixing hole.

[0073] Therefore, commands to unlock or lock are transmitted to electronic locks via mobile phones and other electronic devices;

[0074] Therefore, a two-step locking method is set up to ensure the stability and reliability of the locking. At the same time, the two locking relationships are parallel, that is, if one locking method fails, the other locking method can still complete the locking function, thus further improving the stability and reliability of the locking.

[0075] Therefore, the electronic lock in the metering box can transmit information to electronic devices such as mobile phones, which can then record the location of the metering box, thus enabling accurate location of all metering boxes.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
