Technical Field

[0001] This application relates to the field of power system safety equipment, and more specifically, to a grounding stake lock. Background Technology

[0002] Grounding stake locks are primarily used to ensure the safe grounding of electrical equipment during maintenance. However, existing grounding stake locks have a critical drawback: they cannot simultaneously monitor both the insertion and removal of the grounding wire.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Figure 1 This is a first schematic diagram of the structural composition of the locking mechanism provided in the embodiments of this application; Figure 2 This is a schematic diagram illustrating the structural composition of a grounding stake lock provided in an embodiment of this application. Figure 1-2 As shown, a grounding stake lock includes: a grounding stake 100 and a locking mechanism 200.

[0034] The grounding stake 100 is provided with a plug hole 110 for receiving the insertion or removal of the grounding head 300 to achieve electrical connection.

[0035] The grounding stake 100 supports the locking mechanism 200. The locking mechanism 200 includes a lock cylinder module 210 and a wireless chip 220. The lock cylinder module 210 includes a locking shaft 2110, one end of which extends into the insertion hole 110, and the other end of which is provided with a magnetic element 270. The wireless chip 220 is disposed opposite to the magnetic element 270 and has a first code value and a second code value. When the ground wire head 300 is not inserted into the insertion hole 110, one end of the locking shaft 2110 extends into the insertion hole 110, the magnetic element 270 moves away from the wireless chip 220, and the wireless chip 220 is at the first code value. When the ground wire head 300 is inserted into the insertion hole 110, one end of the locking shaft 2110 exits from the insertion hole 110, the magnetic element 270 moves closer to the wireless chip 220, and the wireless chip 220 is at the second code value.

[0036] Specifically, the locking mechanism 200 is mounted on the grounding stake 100 by fastening screws 260, so that the locking mechanism 200 and the grounding stake 100 form an integral structure, providing stable support and an operating platform. For example, the locking mechanism 200 and the grounding stake 100 can be designed as a single piece.

[0037] The grounding head 300 is used to connect the grounding wire in the field, passing through the insertion hole 110 on the grounding stake 100. It is locked by a wing nut 320 to ensure that the grounding head 300 is firmly fixed to the grounding stake 100. The grounding head 300 can be inserted into or pulled out of the insertion hole 110 on the grounding stake 100. This action triggers a state change of the locking mechanism 200, thereby locking and unlocking the grounding head 300. The grounding head 300 adopts a quick-plug design, which can improve operational efficiency.

[0038] The locking mechanism 200 includes a lock cylinder module 210 and a wireless chip 220. The lock cylinder module 210 includes a locking shaft 2110, one end of which extends into the insertion hole 110 to control the engagement state of the ground wire 300. The other end of the locking shaft 2110 is provided with a magnetic element 270. The wireless chip 220 is disposed opposite to the magnetic element 270 and has a first code value and a second code value. These code values ​​represent different states of the ground wire 300; for example, the first code value indicates that the ground wire 300 is not inserted, while the second code value indicates that the ground wire 300 is inserted. Furthermore, the locking mechanism 200 is designed to be waterproof and dustproof to ensure reliability in harsh environments.

[0039] When the ground wire head 300 is inserted into the socket 110 of the grounding stake 100, one end of the locking shaft 2110 is withdrawn from the socket 110, causing the magnetic element 270 on the locking shaft 2110 to approach the wireless chip 220, allowing the magnetic field of the magnetic element 270 to influence the wireless chip 220. This approach triggers the wireless chip 220 to switch from the first code value to the second code value, clearly indicating that the ground wire head 300 has been correctly inserted. Conversely, when the ground wire head 300 is not inserted into the socket 110, one end of the locking shaft 2110 extends into the socket 110, causing the magnetic element 270 to move away from the wireless chip 220, and the magnetic field of the magnetic element 270 cannot influence the wireless chip 220. In this state, the wireless chip 220 remains at the first code value, indicating that the ground wire head 300 is not engaged.

[0040] The dual-state identification mechanism of the wireless chip 220 can provide real-time feedback on the insertion and removal status of the ground wire head 300, enhancing the reliability of the ground wire stake lock and the user's operational convenience, ensuring the safety of power equipment during maintenance, and avoiding potential risks caused by the ground wire head 300 not being properly connected.

[0041] In one embodiment, Figure 3 This is an exploded view of the overall structure of the grounding stake lock provided in the embodiments of this application; as shown... Figure 3 As shown, the grounding stake lock also includes a control key 400, which includes a sensing unit 410 for reading the code value of the wireless chip 220.

[0042] Specifically, when the ground wire connector 300 is inserted, the sensor unit 410 on the control key 400 can read the code value of the wireless chip 220 to confirm that the operator knows that the ground wire connector 300 has been safely connected.

[0043] Similarly, when the ground wire connector 300 is disconnected, the code value of the wireless chip 220 can be read by the sensing unit 410 on the control key 400 to confirm this, ensuring that the operator confirms the status of the ground wire connector 300 before proceeding to the next step. For example, the sensing unit 410 of the control key 400 is designed to prevent unauthorized access, ensuring that only authorized personnel can read the status of the wireless chip 220, thus enhancing system security.

[0044] In one embodiment, Figure 4 This is a schematic diagram of the structural composition of the wireless chip provided in the embodiments of this application, as shown below. Figure 3 and Figure 4As shown, the wireless chip 220 is a passive electronic component whose working principle is based on the sensing capability of the reed switch 223 to changes in magnetic fields. The wireless chip 220 consists of a plastic housing 221, a PCB board 222, and the reed switch 223, with a built-in chip that can switch the code value stored inside the chip according to the changes in the magnetic field sensed by the reed switch 223. When the magnetic element 270 (such as a magnet) on the locking shaft 2110 approaches or moves away from the reed switch 223, the internal circuitry of the reed switch 223 will be attracted or disconnected due to magnetic force. This process causes the chip code value to switch between a first code value and a second code value, thus establishing the connection state of the wireless communication ground wire 300. Code value recognition of the wireless chip 220 is achieved through a sensing unit 410 on the control key 400. The sensing unit 410 provides an induced current to trigger the wireless chip 220, causing it to provide a signal return, thus enabling the reading of the code value. This design allows the wireless chip 220 to operate without an external power supply, extending its service life and improving the reliability and security of the device.

[0045] In one embodiment, Figure 5 This is a schematic diagram illustrating the structural composition of a ground wire connector provided in an embodiment of this application. Figure 5 As shown, the grounding stake lock also includes a grounding head 300, which includes a grounding head rod 310 and a locking part 330 connected to each other; the locking part 330 has a groove 331 on the side near the grounding head rod 310 and a tapered inclined surface 332 on the side away from the grounding head rod 310; when the locking part 330 of the grounding head 300 is fully inserted into the insertion hole 110, one end of the locking shaft 2110 abuts against the groove 331.

[0046] Specifically, the grounding head 300 consists of a grounding head rod 310 and a locking part 330. The grounding head rod 310 is used to connect the grounding wire, while the locking part 330 is responsible for interacting with the locking shaft 2110 to lock and unlock the grounding head 300. The locking part 330 has a groove 331 on the side near the grounding head rod 310. When the locking part 330 is fully inserted into the insertion hole 110, one end of the locking shaft 2110 abuts against the groove 331, ensuring the grounding head 300 is correctly locked in place. The side of the locking part 330 away from the grounding head rod 310 is designed as a tapered slope 332. This tapered slope 332 pushes the locking shaft 2110 in the locking mechanism 200 to move when the grounding head 300 is partially inserted into the insertion hole 110.

[0047] In one embodiment, Figure 6 This is a schematic diagram of the locking shaft provided in an embodiment of this application, as shown below. Figure 1 and Figure 6 As shown, the lock cylinder module 210 also includes a lock button 2120 and a lock tongue 2130.

[0048] The locking button 2120 is used for rotation; the locking tongue 2130 abuts perpendicularly to the locking button 2120, and the rotation of the locking button 2120 causes the locking tongue 2130 to move to the locked or unlocked state; the locking tongue 2130 is perpendicularly arranged to the locking shaft 2110; the locking shaft 2110 has a first groove 2111 and a second groove 2112, the first groove 2111 and the second groove 2112 are connected in a stepped manner, and the depth of the first groove 2111 is greater than that of the second groove 2112. The depth of the two slots 2112 is such that the second slot 2112 is located on the side closer to the insertion hole 110, and the first slot 2111 is located on the side farther from the insertion hole 110. When the ground wire head 300 is fully inserted into the insertion hole 110 or not inserted into the insertion hole 110 in the locked state, the latch 2130 abuts against the first slot 2111. When the ground wire head 300 is partially inserted into the insertion hole 110 in the unlocked state, the latch 2130 abuts against the second slot 2112. The first elastic member 2131 abuts against the end of the latch 2130 away from the locking shaft 2110; the third elastic member 2114 abuts against the end of the locking shaft 2110 away from the insertion hole 110.

[0049] Specifically, Figure 7 This is a schematic diagram of the structure of the grounding stake lock in the locked state when the grounding head is not inserted, as provided in the embodiments of this application. Figure 8 This is a schematic diagram showing the structural composition of the grounding stake locking button when rotated approximately 65°, as provided in an embodiment of this application. Figure 7-8 As shown, the locking button 2120 is used to rotate in conjunction with the key unlocking lever 420 of the control key 400 to lock and unlock the locking shaft 2110. The control key 400 is the part directly operated by the operator.

[0050] The latch 2130 abuts perpendicularly to the button 2120. Rotation of the button 2120 causes the latch 2130 to move between locked and unlocked states. For example, the end of the button 2120 has a sliding groove that abuts perpendicularly to the latch 2130. When the button 2120 rotates, the sliding groove presses against the latch 2130, causing it to move. The sliding groove can be a semi-cylinder. The design of the latch 2130 ensures precise engagement with the locking shaft 2110, providing a reliable locking mechanism. A first elastic element 2131, such as a spring, abuts against the end of the latch 2130 away from the locking shaft 2110, providing a restoring force to ensure the latch 2130 returns to its initial position after operation. The other end of the first elastic element 2131 has a plug 280, which in the lock cylinder module 210 mainly serves to fix the spring, protect internal components, ensure operational stability, and prevent external contamination.

[0051] The locking shaft 2110 is a key transmission component in the lock cylinder module 210. One end extends into the insertion hole 110, and the other end is equipped with a magnetic element 270, which is positioned opposite to the wireless code chip 220. The locking shaft 2110 has two stepped grooves, namely the first groove 2111 and the second groove 2112. These two grooves have different depths and their positions have specific functions. A third elastic element 2114, such as a spring, abuts against the end of the locking shaft 2110 away from the insertion hole 110, providing stable support and restoring force for the locking shaft 2110, ensuring that the locking shaft 2110 can return to its initial position after operation.

[0052] The first slot 2111 is deeper than the second slot 2112 and is located on the side of the locking shaft 2110 away from the insertion hole 110, while the second slot 2112 is located on the side closer to the insertion hole 110. In the locked state, when the ground wire 300 is fully inserted or not inserted into the insertion hole 110, the locking tongue 2130 abuts against the first slot 2111, ensuring that the locking shaft 2110 is fixed in the correct position. In the unlocked state, when the ground wire 300 is partially inserted into the insertion hole 110, the locking tongue 2130 abuts against the second slot 2112, allowing the locking shaft 2110 to move.

[0053] In one embodiment, such as Figure 1 and Figure 7 As shown, the lock cylinder module 210 also includes: a lock tongue limiting shaft 2140 and a second elastic element 2141.

[0054] The latch limiting shaft 2140 is perpendicular to the latch 2130 and is used to abut against the latch 2130 to limit the self-resetting of the latch 2130. The second elastic element 2141 abuts against the end of the latch limiting shaft 2140 away from the latch 2130.

[0055] Specifically, the latch limiting shaft 2140 is perpendicular to the latch 2130. As a key limiting element, it directly abuts against the latch 2130 to limit its self-resetting action. Specifically, the second slot 2112 engages with the latch limiting shaft 2140 in the unlocked state to limit the self-resetting of the latch 2130, ensuring that the latch 2130 remains in the required position during unlocking, preventing accidental reset due to spring force or other external forces, thereby improving the security and operational accuracy of the lock system.

[0056] The second elastic element 2141, such as a spring, abuts against the end of the latch limiting shaft 2140 away from the latch 2130, providing necessary elastic support for the latch limiting shaft 2140. Its function is to provide restoring force during the operation of the latch limiting shaft 2140, ensuring that the latch limiting shaft 2140 can quickly and accurately return to its initial position after operation. The other end of the second elastic element 2141 is provided with a plug 280.

[0057] In one embodiment, Figure 9 This is a schematic diagram of the structure of the grounding stake lock in the unlocked state when it is fully inserted into the conical inclined surface of the grounding head, as provided in the embodiments of this application. Figure 1 and Figure 7-9 As shown, the latch 2130 includes a first latch groove 2132, a second latch groove 2133, and an end position 2134 connected in sequence; the first latch groove 2132 abuts against the lock button 2120; in the locked state, the second latch groove 2133 abuts against the latch limiting shaft 2140; in the unlocked state, when the ground wire head 300 is not inserted into the insertion hole 110, the latch limiting shaft 2140 abuts against the end position 2134, and when the ground wire head 300 is partially inserted into the insertion hole 110, the latch limiting shaft 2140 disengages from the end position 2134.

[0058] Specifically, the latch 2130 directly abuts against the button 2120 through the first latch groove 2132, so that the rotation of the button 2120 can directly drive the latch 2130 to switch between the locked and unlocked states.

[0059] In the locked state, such as Figure 7 As shown, the latch limiting shaft 2140 abuts against the second latch groove 2133 in a first direction. This interaction ensures the stability of the latch 2130 in the locked position. When in the unlocked state, and the ground wire head 300 is not inserted into the connector hole, as... Figure 8 As shown, the latch limiting shaft 2140 abuts against the end position 2134 of the latch 2130, and under the elastic force of the second elastic member 2141, the latch limiting shaft 2140 abuts against the second latch groove 2133 in the second direction, restricting the self-resetting of the latch 2130 under the pressure of the first elastic member 2131, so as to keep the latch 2130 in the unlocked position and ensure that the unlocked state of the lock is effectively maintained. When the local wire end 300 is inserted into the plug hole 110, as Figure 9 As shown, the locking tongue limiting shaft 2140 disengages from the end position 2134, releasing the limiting effect on the locking tongue 2130. The locking tongue 2130 then self-resets and presses onto the second slot 2112 of the locking shaft 2110.

[0060] This design improves the overall responsiveness and operational stability of the system, thus providing a better user experience, especially in situations requiring frequent locking and unlocking.

[0061] In one embodiment, such as Figure 9As shown, the locking tongue limiting shaft 2140 and the locking shaft 2110 are arranged in parallel. The locking shaft 2110 has a boss 2113. When the ground wire head 300 is inserted into the insertion hole 110, the boss 2113 abuts against the locking tongue limiting shaft 2140. The locking shaft 2110 moves away from the insertion hole 110, which drives the locking tongue limiting shaft 2140 to move away from the locking tongue 2130.

[0062] Specifically, the parallel arrangement of the latch limiting shaft 2140 and the locking shaft 2110 achieves precise synchronization of operation. The latch limiting shaft 2140 not only restricts the self-resetting of the latch 2130, but also works in conjunction with the boss 2113 and stepped groove on the locking shaft 2110 to precisely control the position of the latch 2130. When the ground wire end 300 is partially inserted into the insertion hole 110, the locking shaft 2110 moves away from the insertion hole 110. After moving to a specific position, it triggers the boss 2113 on the locking shaft 2110 to abut against the latch limiting shaft 2140, causing the latch limiting shaft 2140 to move away from the latch 2130 until the insertion of the ground wire end 300 is completed, thereby releasing the limiting effect on the latch 2130. The latch 2130 then self-resets and presses against the second groove 2112 of the locking shaft 2110.

[0063] The movement of the locking shaft 2110 drives the latch limiting shaft 2140 to move away from the latch 2130, automatically releasing the limiting effect on the latch 2130 and allowing the latch 2130 to self-reset. This process requires no additional operation, improving the convenience and efficiency of releasing the limit. It also reduces errors caused by improper human operation, such as forgetting to release the limit, thereby improving the overall system's safety and reliability.

[0064] In one embodiment, Figure 10 This is a second schematic diagram showing the structural composition of the locking mechanism provided in the embodiments of this application, as shown below. Figure 10 As shown, the locking mechanism 200 also includes a housing 230, a locking pin 250, and an unlocking pin 240. The surface of the housing 230 is provided with a locking hole 231, a locking pin limiting hole 251, and an unlocking pin limiting hole 241. The locking pin limiting hole 251 and the unlocking pin limiting hole 241 are perpendicular to the locking hole 231. The locking pin 2120 is located inside the locking hole 231, and the unlocking pin limiting hole 241 is located in the locking hole 231 away from the locking pin 2120. The locking pin 250 passes through the locking pin limiting hole 251 and abuts against the limiting groove of the locking pin 2120. The unlocking pin 240 passes through the unlocking pin limiting hole 241 and partially extends into the locking hole 231.

[0065] Specifically, the housing 230 constitutes the main structure of the locking mechanism 200, providing a reliable mounting base for the locking button 2120 and the limiting pin. The surface of the housing 230 is provided with a dedicated locking button hole 231 to accommodate the locking button 2120, allowing it to rotate freely within the hole. The key unlocking lever 420 extends into the locking button hole 231 and engages with the locking button 2120 to perform the rotation operation. The locking button 2120 is fixed to the lock body by the locking button limiting pin 250, ensuring its positional stability and operational precision. Furthermore, the housing 230 is also provided with a locking button limiting hole 251 and an unlocking limiting hole 241, which are perpendicular to the locking button hole 231 and are used for the installation of the locking button limiting pin 250 and the unlocking limiting pin 240, respectively, thereby ensuring precise control of the operation of the locking button 2120.

[0066] The unlocking limit pin 240 is positioned away from the locking button 2120. It passes through the unlocking limit hole 241 and partially extends into the locking button hole 231, effectively preventing the lock from being opened by rotating it with a screwdriver or tweezers (or other non-dedicated key). The locking torsion limit pin 250 is positioned close to the locking button 2120. It passes through the locking torsion limit hole 251 and engages with the locking torsion groove of the locking button 2120 to ensure precise positioning of the locking button 2120 during operation and to limit its excessive rotation. This prevents damage to the lock or safety accidents that might occur due to improper operation or external force causing excessive rotation of the locking button 2120, further enhancing the security of the locking mechanism 200.

[0067] The usage process of the ground wire lock in this embodiment is as follows:

[0068] The unlocking process of the locking mechanism, such as Figure 7 and Figure 8 As shown:

[0069] When the control key 400 and key unlocking lever 420 are inserted into the lock button hole 231, and the sensing unit 410 correctly identifies the code value (e.g., the first code value), the key unlocking lever 420 rotates, causing the lock button 2120 to rotate. At the same time, the lock button 2120 cooperates with the horizontal lock tongue 2130, and rotating the lock button 2120 also causes the lock tongue 2130 to move to the left. After rotating to the unlock position, the lock tongue limiting shaft 2140 will move forward under the push of the elastic element behind it, limiting the lock tongue 2130 from self-resetting under the pressure of the elastic element. After this process, the locking shaft 2110 is unlocked. Then, the key unlocking lever 420 causes the lock button 2120 to self-reset. The control key 400 is then pulled out, completing the unlocking operation of the locking module.

[0070] The process of inserting the ground wire 300, as follows: Figure 9 and Figure 11 As shown:

[0071] With the device unlocked, the ground wire head 300 is inserted into the connector 110. During this process, as follows: Figure 9 As shown, the tapered ramp 332 of the ground wire head 300 can push the locking shaft 2110 upward. As the tapered ramp 332 of the ground wire head 300 is gradually fully inserted into the ground wire stake 100, the boss 2113 on the locking shaft 2110 will connect with the locking tongue limiting shaft 2140 and drive it upward together. During this process, the locking tongue 2130 cannot be reset due to the restriction of the second slot 2112 on the locking shaft 2110, and the locking shaft 2110 can continue to move upward until the tapered ramp 332 of the ground wire head 300 is fully inserted. After this process, the locking shaft 2110 moves to the highest point, and the magnetic element 270 set on it will approach the wireless chip 220 and trigger the wireless chip 220 to change the code value.

[0072] Figure 11 This is a schematic diagram of the structure when the ground wire head is fully inserted into the ground wire stake and locked, as provided in the embodiments of this application. Figure 11 As shown, the ground wire head 300 is continuously pushed in until the groove 331 is directly below the locking shaft 2110. At this time, the locking shaft 2110 and the locking tongue limiting shaft 2140 press the ground wire head 300 under the action of the corresponding elastic element. The locking tongue 2130 then self-resets and presses onto the second groove 2112 of the locking shaft 2110 to lock the locking shaft 2110. Because the reed switch 223 is magnetized, the height to which the locking shaft 2110 descends into the groove 331 will not cause the code value to switch. At this time, when the control key 400 is inserted into the lock, the sensing unit 410 reads the second code value after the ground wire head 300 is inserted, confirming that the ground wire head 300 has been accurately inserted into the ground wire stake 100 and locking is performed. As with the above-described locking mechanism 200, after unlocking, after the ground wire head 300 is pulled out, the locking shaft 2110 is fully reset, and the code value of the wireless chip 220 returns to the first code value before the ground wire head 300 was inserted. This method can realize the recognition of the insertion and removal status of the ground wire head 300. The unlocking process of the locking mechanism and the step of pulling out the ground wire head 300 are similar to those described above, and will not be repeated here.

[0073] In summary, the technical solution provided by the embodiments of this utility model has the following advantages:

[0074] Through the interaction between the wireless chip 220 and the magnetic element 270 on the locking shaft 2110, the insertion and removal status of the ground wire head 300 can be accurately monitored, significantly improving the safety during the maintenance of power equipment.

[0075] The use of the passive wireless chip 220 reduces the risk of system failure due to power issues and enhances overall reliability. Because the wireless chip 220 does not require an external power supply, it can operate stably in various environments, unaffected by power fluctuations or battery aging.

[0076] The grounded lock employs a mechanical structure, reducing reliance on electronic components and external power supplies, effectively lowering manufacturing and maintenance costs while also simplifying maintenance. This design simplifies the lock's structure, reduces maintenance needs due to electronic component failures, and lowers long-term operating costs.

[0077] The modular design of each component allows for quick replacement of parts and system upgrades. Different models of components can be used interchangeably, improving the system's flexibility and compatibility while reducing long-term operating costs.

[0078] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0079] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
