[0002] A grounding lock is an electrical safety device with a mechanical locking mechanism, primarily used in power systems such as substations and distribution rooms. Its core function is to ensure the safety of equipment during grounding operations. In electrical work, before any maintenance or repair of electrical equipment, a grounding operation must be performed using a grounding lock to reliably connect the equipment to the earth, release residual charge, and prevent electric shock or equipment damage from sudden power surges. The grounding lock also allows for verification of the reliability of the grounding operation; only after a correct and reliable grounding operation can the next step be performed, preventing misoperation.

[0003] With the rapid development of the power industry, the requirements for the reliability and stability of grounding operation of power equipment are increasing. However, the existing grounding locks have poor sealing performance and cannot effectively resist interference from factors such as water vapor, dust, and insects in harsh environments (such as outdoor environments) (especially after the grounding wire is inserted), resulting in a short service life and poor grounding reliability.

[0006] The grounding lock device provided by this utility model has at least the following beneficial effects: By opening a socket in the lock housing that communicates with the chamber, a slider is placed in the socket and slides in cooperation with it. When the grounding component is inserted into the socket, the slider is pushed and slides along the socket, triggering the trigger switch. This allows the slider to perform both the triggering function and the function of isolating the chamber from the outside. The grounding lock device has good sealing performance before and after grounding, effectively reducing the risk of external debris entering the chamber, improving service life, and enhancing grounding reliability. It can be better applied to various harsh environments such as outdoor environments.

[0007] In one embodiment of this implementation, a through hole is provided on the side wall of the socket, and the grounding lock device includes a self-locking mechanism disposed in the cavity. The self-locking mechanism is used to extend into the through hole and cooperate with the grounding member to prevent the grounding member from exiting the socket.

[0008] In one embodiment of this implementation, the self-locking mechanism includes a latch and a limiting component. The lock housing has a groove communicating with the through hole. The latch slides in the groove. The limiting component is installed in the cavity and abuts against the latch so that the latch maintains a engagement with the grounding member.

[0009] In one embodiment of this implementation, the lock housing has an unlocking hole communicating with the chamber, and the grounding lock device includes an actuating member for inserting into the unlocking hole and driving the limiting component to separate from the lock tongue.

[0010] In one embodiment of this implementation, the grounding lock device includes a first elastic element that abuts against the latch to apply an elastic force to the latch, enabling it to extend into the through hole.

[0011] In one embodiment of this implementation, the grounding lock device includes a second elastic member disposed in the cavity and abutting against the slider. The second elastic member can be compressed when the grounding member pushes the slider.

[0012] In one embodiment of this implementation, the grounding lock device includes a grounding base and an adapter sleeve. The grounding base is located on the outside of the lock housing and has a connecting hole opposite to the insertion hole. The adapter sleeve has an internal threaded hole, which forms a limiting boss. The internal threaded hole is used for the grounding member to pass through, so that the grounding member can pass through the connecting hole and be inserted into the insertion hole. The internal threaded hole can be threadedly engaged with the grounding base, so that the grounding base and the limiting boss clamp the positioning boss on the grounding member from both sides.

[0013] In one embodiment of this implementation, the grounding base includes a body portion and an external threaded sleeve disposed on the body portion. The body portion is used to connect with electrical equipment. The external threaded sleeve has the connection hole and can cooperate with the internal threaded hole. The grounding lock device includes a sealing plug, which can be connected to the external threaded sleeve to seal the connection hole.

[0014] In one embodiment of this implementation, there are multiple trigger switches, which are symmetrically arranged on both sides of the slider. Each trigger switch is provided with a contact and a spring, and the multiple springs can be pushed by the slider to simultaneously abut against the corresponding contact.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 , Figure 1 This is a schematic diagram of the grounding lock device 100 in one embodiment of the present invention, viewed from the front. Figure 2 yes Figure 1A schematic diagram of the grounding lock device 100 viewed from the left. Figure 3 yes Figure 2 A cross-sectional view of the grounding lock device 100 in the AA direction; Figure 5 yes Figure 2 A cross-sectional view of the grounding lock device 100 in the grounded state along the AA direction. This utility model provides a grounding lock device 100, which includes a lock housing 10, a trigger switch 20, and a slider 30. The lock housing 10 has a chamber 101 and an insertion hole 102 communicating with the chamber 101 for inserting a grounding member 200. The trigger switch 20 is located within the chamber 101. The slider 30 is inserted into the insertion hole 102 and slides within it. When the grounding member 200 is inserted into the insertion hole 102, the slider 30 is pushed by the grounding member 200 and slides along the insertion hole 102 to trigger the trigger switch 20.

[0025] Specifically, the lock housing 10 is used for installation on electrical equipment such as distribution boxes. The grounding member 200 can be a ground wire head connected to a grounding stake to facilitate the release of static electricity from the electrical equipment to the ground through the grounding stake. The trigger switch 20 is constructed as a micro switch.

[0026] Specifically, the slider 30 is positioned at one end of the socket 102, and the grounding member 200 can be inserted from the other end of the socket 102. For example... Figure 3 When the grounding component 200 is not inserted, the slider 30 is in the first position of the socket 102, and the slider 30 can prevent foreign objects from entering the chamber 101 from the socket 102. Figure 5 When the grounding member 200 is inserted and grounding is completed, the slider 30 is pushed to the second position by the grounding member 200. The slider 30 is in the second position of the socket 102. The slider 30 can still prevent foreign objects from entering the chamber 101 from the socket 102.

[0027] Specifically, the slider 30 and the socket 102 are in transition fit to ensure that the gap between the slider 30 and the side wall of the socket 102 is appropriate, the slider 30 can slide smoothly in the socket 102, and foreign objects are not easy to pass through the gap.

[0028] Specifically, in order to ensure sealing while simplifying the structure, facilitating processing, and reducing costs, the part of the slider 30 that slides into the socket 102 is cylindrical, and the socket 102 is a round hole.

[0029] By opening a socket 102 in the lock housing 10 that communicates with the chamber 101, the slider 30 is placed in the socket 102 and slides in cooperation with the socket 102. When the grounding member 200 is inserted into the socket 102, the slider 30 is pushed by it and slides along the socket 102, triggering the trigger switch 20. This allows the slider 30 to perform both the triggering function and the function of isolating the chamber 101 from the outside. The grounding lock device 100 has good sealing performance before and after grounding, effectively reducing the risk of external debris entering the chamber 101, improving service life, and enhancing grounding reliability. It can be better applied to various harsh environments such as outdoor environments.

[0030] In one embodiment of this implementation, please refer to Figure 3 and Figure 5 The side wall of the socket 102 has a through hole 103. The grounding lock device 100 includes a self-locking mechanism 40, which is located in the chamber 101. The self-locking mechanism 40 extends into the through hole 103 and cooperates with the grounding member 200 to prevent the grounding member 200 from exiting the socket 102. This configuration allows the self-locking mechanism 40 to fix the position of the grounding member 200 in the socket 102, reducing the risk of the grounding member 200 accidentally exiting the socket 102 and improving grounding reliability. Simultaneously, since the through hole 103 is located on the side wall of the socket 102 and the self-locking mechanism 40 extends into the through hole 103, the self-locking mechanism 40 can seal the through hole 103, achieving the locking function while maintaining as much sealing as possible.

[0031] In one embodiment of this implementation, please refer to Figure 3 and Figure 5 The self-locking mechanism 40 includes a latch 41 and a limiting component 42. The lock housing 10 has a groove 104 communicating with the through hole 103. The latch 41 is slidably engaged with the groove 104. The limiting component 42 is installed in the chamber 101 and abuts against the latch 41 to keep the latch 41 engaged with the grounding member 200. By opening the groove 104 in the lock housing 10 communicating with the through hole 103, the latch 41 is slidably engaged with the groove 104, so that the latch 41 can move relative to the through hole 103 by sliding relative to the groove 104. This allows the latch 41 to engage with the grounding member 200 to prevent the grounding member 200 from exiting the socket 102, or to separate from the grounding member 200, releasing the restriction on the grounding member 200. At the same time, the limiting component 42 can abut against the latch 41 to prevent the latch 41 from exiting the through hole 103, thereby keeping the latch 41 engaged with the grounding member 200 and further improving the reliability of grounding.

[0032] Specifically, the grounding member 200 has an arc-shaped groove on its outer periphery for engaging with the latch 41. It is understood that when the limiting component 42 releases the latch 41, the grounding member 200, during its withdrawal from the socket 102, can push the latch 41 away from the socket 102, thus not restricting the withdrawal of the grounding member 200. The arc-shaped groove on the grounding member 200 facilitates the movement of the latch 41 through its arc-shaped inner wall.

[0033] Specifically, the sliding direction of the locking tongue 41 in the slide groove 104 is perpendicular to the sliding direction of the slider 30 in the socket 102.

[0034] Specifically, one end of the locking tongue 41 engages with the arc-shaped groove of the grounding member 200, and the other end of the locking tongue 41 abuts against the limiting member 42.

[0035] Specifically, to ensure good sealing performance of the slide groove 104, the part of the locking tongue 41 that slides into the slide groove 104 is cylindrical. The slide groove 104 is constructed as a sealing groove with a circular cross-section. In the extension direction of the slide groove 104, the slide groove 104 has a first opening and a second opening. The first opening communicates with the through hole 103, allowing one end of the locking tongue 41 to extend into the through hole 103 through the first opening. The second opening is adjacent to the limiting component 42, allowing the other end of the locking tongue 41 to extend out of the slide groove 104 through the second opening, so that the limiting component 42 abuts against this end and functions to keep the locking tongue 41 engaged with the grounding component 200.

[0036] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The self-locking mechanism 40 includes a button 43 disposed on the lock housing 10. The button 43 is electrically connected to the limiting component 42 and is used to control the separation of the limiting component 42 from the bolt 41, so that the grounding member 200 can be inserted into or removed from the socket 102. With this configuration, the user can perform grounding operation or release grounding operation through the button 43.

[0037] Specifically, button 43 can be electrically connected to limiting component 42 via wires or other means.

[0038] Specifically, the limiting component 42 includes a solenoid 421 and an iron core 422. The iron core 422 is disposed inside the solenoid 421. The solenoid 421 is used to generate a magnetic field by passing electricity through it, so as to separate the iron core 422 from the locking tongue 41. With this configuration, the iron core 422 can be driven to move relative to the locking tongue 41 by passing electricity through the solenoid 421, so that the iron core 422 abuts against or separates from the locking tongue 41.

[0039] Specifically, when the solenoid 421 is energized, the resulting magnetic field can drive the iron core 422 to separate from the locking tongue 41, allowing the locking tongue 41 to slide along the slide groove 104 and the grounding member 200 to retract from the socket 102. When the solenoid 421 is not energized, the iron core 422 remains in contact with one end of the locking tongue 41, so that in the grounded state, the grounding member 200 cannot retract from the socket 102, or in the uncontacted state, the grounding member 200 cannot be inserted into the socket 102.

[0040] In one embodiment of this implementation, please refer to Figure 1 , Figure 3 and Figure 5 The lock housing 10 has an unlocking hole (not shown) communicating with the chamber 101. The grounding lock device 100 includes an actuating member (not shown) that is inserted into the unlocking hole and causes the limiting component 42 to separate from the bolt 41. This configuration allows the bolt 41 to be released from the grounding component 200 in an emergency by means of the actuating member, thus improving applicability.

[0041] Specifically, the unlocking hole is located adjacent to the iron core 422. In emergency situations such as button 43 malfunction or solenoid 421 failing to receive power, an actuating component can be inserted into the unlocking hole to separate the iron core 422 from the latch 41, allowing the grounding component 200 to exit or be inserted into the socket 102. In this embodiment, the actuating component is constructed as a key. The user can insert the key into the unlocking hole and turn it to move the iron core 422 relative to the solenoid 421.

[0042] Specifically, the unlocking hole cover of the lock case 10 is provided with an unlocking cover 11, which closes the unlocking hole when the actuating component is not needed, preventing debris from entering the chamber 101 through the unlocking hole. When the actuating component is needed, the user can remove the unlocking cover 11, exposing the unlocking hole, allowing the actuating component to be inserted through the unlocking hole. This improves usability while ensuring service life and reliability.

[0043] In one embodiment of this implementation, please refer to Figure 3 and Figure 5The grounding lock device 100 includes a first elastic element 51, which abuts against the latch 41 to apply an elastic force to the latch 41, enabling it to extend into the through hole 103. Thus, the first elastic element 51 can reset the latch 41, placing it within the through hole 103. Specifically, after the solenoid 421 is energized and the grounding member 200 has been inserted into or withdrawn from the socket 102, the first elastic element 51 can drive the latch 41 back into the through hole 103, protruding to a certain extent relative to the side wall of the socket 102, to maintain engagement with the grounding member 200 or restrict the insertion of the grounding member 200 into the socket 102.

[0044] Specifically, the first elastic element 51 is constructed as a spring and is located inside the slide groove 104, sleeved on the outer periphery of the locking tongue 41.

[0045] In one embodiment of this implementation, please refer to Figure 3 and Figure 5 The grounding lock device 100 includes a second elastic element 52, which is disposed in the chamber 101 and abuts against the slider 30. The second elastic element 52 can be compressed when the grounding member 200 pushes the slider 30. With this configuration, the slider 30 can be reset by the second elastic element 52 after the grounding member 200 leaves the socket 102.

[0046] In this embodiment, the slider 30 is provided with an actuation rib 31 for triggering the trigger switch 20, and the inner wall of the lock housing 10 has an annular protrusion, with the insertion hole 102 located on the end face of the annular protrusion. Under the action of the second elastic member 52, the actuation rib 31 can abut against the end face of the annular protrusion to further seal the insertion hole 102. With this configuration, before the grounding member 200 is inserted into the insertion hole 102, the insertion hole 102 has sufficient sealing properties, which can better resist interference in harsh environments.

[0047] In one embodiment of this implementation, please refer to Figure 1 , Figure 5 and Figure 6 , Figure 6 yes Figure 5An enlarged schematic diagram of region I. The grounding lock device 100 includes a grounding base 61 and an adapter sleeve 62. The grounding base 61 is located on the outside of the lock housing 10 and has a connecting hole 6101 opposite to the insertion hole 102. The adapter sleeve 62 has an internal threaded hole 6201, which forms a limiting boss 6202. The internal threaded hole 6201 is used for the grounding member 200 to pass through, so that the grounding member 200 can pass through the connecting hole 6101 and be inserted into the insertion hole 102. The internal threaded hole 6201 can be threadedly engaged with the grounding base 61, so that the grounding base 61 and the limiting boss 6202 clamp the positioning boss 210 on the grounding member 200 from both sides. With this configuration, the grounding base 61 and the grounding component 200 can be connected via the adapter sleeve 62, and the grounding component 200 can be inserted into the socket 102. At the same time, after installation, the limiting boss 6202 can cooperate with the grounding base 61 to clamp the positioning boss 210, so that the grounding component 200 can be stably connected to the grounding base 61 and can help maintain the position of the grounding component 200 in the socket 102, thereby effectively improving the reliability of grounding.

[0048] Specifically, the grounding base 61 is fixed to the outside of the lock housing 10 and connected to the electrical equipment for conducting static electricity on the electrical equipment. The adapter sleeve 62 is constructed as a hexagonal nut.

[0049] In one embodiment of this implementation, please refer to Figures 1 to 3 The grounding base 61 includes a body 611 and an external threaded sleeve 612 disposed on the body 611. The body 611 is used for connection with electrical equipment. The external threaded sleeve 612 has a connection hole 6101 and can mate with an internal threaded hole 6201. The grounding lock device 100 includes a sealing plug 63, which can be connected to the external threaded sleeve 612 to seal the connection hole 6101. This arrangement allows the connection hole 6101 to be sealed by the sealing plug 63 after the grounding operation is released, preventing debris from entering the chamber 101 through the connection hole 6101 and the insertion hole 102, thereby improving sealing performance and extending service life.

[0050] Specifically, the sealing plug 63 is connected to the lock housing 10 via a chain 631, so that during grounding operations, the sealing plug 63 can be suspended on the lock housing 10 via the chain 631 to prevent the sealing plug 63 from being lost.

[0051] Specifically, the sealing plug 63 covers the outer periphery of the external threaded sleeve 612 to protect its external threads.

[0052] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 , Figure 4 yes Figure 2A cross-sectional view of the grounding lock device 100 in the BB direction is shown. Multiple trigger switches 20 are symmetrically arranged on both sides of the slider 30. Each trigger switch 20 has a contact 21 and a spring 22. Multiple springs 22 can be pushed by the slider 30 to simultaneously abut against the corresponding contact 21. This arrangement ensures that the springs 22 of each trigger switch 20 experience essentially the same force, which helps extend their service life.

[0053] Specifically, the number of starting ribs 31 is the same as the number of spring pieces 22, and they are set one-to-one. Multiple starting ribs 31 can simultaneously push the corresponding spring pieces 22 when the slider 30 slides, so that multiple spring pieces 22 abut against the corresponding contacts 21 respectively, thereby turning on the circuit.

[0054] Furthermore, there are two starting ribs 31, symmetrically distributed on the slider 30. The length of the starting ribs covers all the spring pieces 22. When the slider 30 slides, the starting ribs 31 can simultaneously push all the spring pieces 22, so that multiple spring pieces 22 abut against the corresponding contacts 21, thereby conducting the circuit. In this process, the force on each spring piece 22 is basically balanced.

[0055] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 The grounding lock device 100 includes a main control board 71 located in the chamber 101 and two circuit boards 72. The two circuit boards 72 are respectively located on both sides of the slider 30 and are opposite to and electrically connected to the corresponding trigger switches 20. The side of the circuit board 72 facing away from the trigger switches 20 is electrically connected to the main control board 71 through a wire. This arrangement allows for wiring from the side of the circuit board 72 facing away from the trigger switches 20, reducing wiring difficulty, preventing the wires from affecting the triggering action of the trigger switches 20, and improving reliability.

[0056] Specifically, the main control board 71 is located on the top side of the slider 30 and above the middle area of ​​the two circuit boards 72, so that the wires of the two circuit boards 72 can be connected to the main control board 71.

[0057] Specifically, the grounding lock device 100 also includes an indicator light 73 on the lock housing 10. The indicator light 73 is electrically connected to the main control board 71 so as to present the grounding status of the electrical equipment through the signal of the trigger switch 20, which is convenient for user operation.

[0058] Specifically, the main control board 71 is electrically connected to the limiting component 42 and the button 43, so that the limiting component 42 can be controlled to separate from the locking tongue 41 according to the input signal of the button 43.

[0059] Specifically, the main control board 71 is equipped with a communication unit so that the user can send signals to the communication unit to control the power supply of the limiting component 42 and realize remote control.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
