Description

Technical Field

[0001] This application relates to the field of circuit breaker technology, and more specifically, to a circuit breaker lock assembly. Background Technology

[0002] In the safety operating procedures of the power system, such as when performing relay protection verification or equipment maintenance, it is necessary to disconnect the relevant circuit breakers to ensure the personal safety of the operators and the safety of the equipment.

[0003] However, non-operating personnel (especially mobile personnel) may accidentally close the circuit breaker without their knowledge or permission, which could lead to electric shock, equipment damage, or even power grid accidents.

[0004] Therefore, how to prevent circuit breakers from being accidentally closed and improve safety is a technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a circuit breaker locking assembly that can prevent circuit breakers from being accidentally closed, thereby improving safety.

[0006] This application is achieved through the following technical solution: This application provides a circuit breaker lock assembly, which includes a circuit breaker lock and a tag. The circuit breaker lock is used to prevent the circuit breaker from closing. The circuit breaker lock has a lock hole for a lock to pass through and lock the circuit breaker lock. The tag includes a retaining ring, a connector, and an identification plate. The retaining ring is sleeved on the outer periphery of the circuit breaker lock, and one end of the identification plate is suspended from the retaining ring by the connector. A warning label is provided on the front of the identification plate.

[0007] The technical solution of this application embodiment prevents the circuit breaker from closing by using a circuit breaker lock, thereby preventing other personnel from accidentally closing the circuit breaker and reducing the risk of electric shock to operators, equipment damage, and power grid accidents, thus improving safety. Simultaneously, by setting up a hanging tag, clear visual warning information is provided, informing all personnel that the equipment is in a prohibited operation state, reducing the risk of other personnel accidentally closing the circuit breaker. Furthermore, by using a retaining ring fitted around the outer periphery of the circuit breaker lock and a connector to suspend the tag from the retaining ring, the reliability and convenience of hanging the tag are improved.

[0008] In some embodiments, the circuit breaker lock includes a circuit breaker lock body and a flange portion, the flange portion protruding from the outer peripheral surface of the circuit breaker lock body, and a retaining ring sleeved on the outer periphery of the flange portion.

[0009] The technical solution of this application embodiment improves the reliability and convenience of hanging signboards by using a retaining ring fitted onto the flange of the circuit breaker lock.

[0010] In some embodiments, the inner circumferential surface of the retaining ring is provided with a groove, and the outer circumference of the flange is embedded in the groove.

[0011] The technical solution of this application embodiment, by embedding the outer periphery of the flange into the groove of the inner periphery of the retaining ring, helps to reduce the risk of the retaining ring detaching from the flange and improves the reliability of the hanging sign.

[0012] In some embodiments, the retaining ring is an open ring.

[0013] The technical solution of this application embodiment, by setting the retaining ring as an open ring, allows the circuit breaker lock to still be fitted onto and removed from the flange of the circuit breaker lock after it is installed on the circuit breaker, which improves the convenience of installing and removing the retaining ring.

[0014] In some embodiments, the central angle corresponding to the opening of the retaining ring is α, which satisfies: 45°≤α≤90°.

[0015] In the technical solution of this application embodiment, when the retaining ring is fitted onto or removed from the flange of the circuit breaker lock, the retaining ring can undergo elastic deformation, causing the opening to expand. After being fitted onto or removed from the flange of the circuit breaker lock, the retaining ring can elastically return to its original position, causing the opening to return to its original position. The central angle α corresponding to the opening of the retaining ring satisfies the above conditions. When α ≥ 45°, the opening is easy to expand, thereby improving the convenience of installation and disassembly; when α ≤ 90°, the opening elastically returns to its original position better after expansion, which helps to improve the reliability of the retaining ring fitted onto the circuit breaker lock.

[0016] In some embodiments, the circuit breaker lock includes a circuit breaker lock body and a flange portion, the flange portion protruding from the outer peripheral surface of the circuit breaker lock body, and a retaining ring sleeved on the outer peripheral surface of the circuit breaker lock body.

[0017] The technical solution of this application embodiment improves the reliability and convenience of hanging signboards by using a retaining ring fitted onto the circuit breaker lock body.

[0018] In some embodiments, the inner circumferential surface of the retaining ring is provided with a protrusion, which abuts against the outer circumference of the circuit breaker lock body.

[0019] The technical solution of this application embodiment provides a protrusion on the inner circumferential surface of the retaining ring, which abuts against the outer circumference of the circuit breaker lock body, thereby improving the reliability of the retaining ring being fitted onto the circuit breaker lock.

[0020] In some embodiments, along the circumferential direction of the circuit breaker lock body, the outer circumferential surface of the circuit breaker lock body includes a first flat surface, a first arc surface, a second flat surface, and a second arc surface connected end to end. Along the circumferential direction of the retaining ring, the inner circumferential surface of the retaining ring includes a third flat surface, a third arc surface, a fourth flat surface, and a fourth arc surface connected end to end. Both the third flat surface and the fourth flat surface are provided with protrusions. The protrusions on the third flat surface abut against the first flat surface, and the protrusions on the fourth flat surface abut against the second flat surface.

[0021] The technical solution of this application embodiment, by having the protrusion on the third flat surface abut against the first flat surface, and the protrusion on the fourth flat surface abut against the second flat surface, is beneficial to improving the reliability of the retaining ring being fitted onto the circuit breaker lock.

[0022] In some embodiments, the retaining ring is provided with a first mounting base and a second mounting base, which are disposed opposite to each other. The first mounting base has a first connecting hole, and the second mounting base has a second connecting hole. The connector includes a middle section, a first connecting section, a second connecting section, a first end section, and a second end section. A hook is provided on the back of the sign, which is connected to the middle section. One end of the middle section is connected to the first end section via the first connecting section, and the other end of the middle section is connected to the second end section via the second connecting section. The first end section is inserted into the first connecting hole, and the second end section is inserted into the second connecting hole. The first connecting section and the second connecting section are bent relative to the middle section, the first end section is bent relative to the first connecting section, and the second end section is bent relative to the second connecting section.

[0023] The technical solution of this application embodiment connects the retaining ring through the first end section and the second end section of the connector, and connects the hook through the middle section of the connector, which helps to improve the convenience of connecting the retaining ring and the tag.

[0024] In some embodiments, the tag further includes a limiting pin, the hook has a limiting hole that extends through the inner and outer sides of the hook, and the limiting pin passes through the limiting hole to prevent the hook from detaching from the middle section.

[0025] The technical solution of this application embodiment prevents the hook from detaching from the middle section by setting a limit pin, which helps to improve the reliability of the connector connecting the tag.

[0036] Please refer to Figures 1 to 5 , Figure 1 A schematic diagram of the circuit breaker provided in this application. Figure 2 This is a schematic diagram of the circuit breaker lock provided in this application. Figure 3 This is a schematic diagram showing the operating part of the circuit breaker lock provided in this application is not pressed. Figure 4 A schematic diagram showing the operation section of the circuit breaker lock provided in this application being pressed. Figure 5 This is a schematic diagram illustrating the interaction between the circuit breaker locking assembly and the circuit breaker provided in this application. Wherein, Figure 1 and Figure 5 The circuit breaker is in the open state. This application provides a circuit breaker lock assembly 1, which includes a circuit breaker lock 10 and a tag 20. The circuit breaker lock 10 is used to prevent the circuit breaker 2 from closing. The circuit breaker lock 10 has a lock hole 15 for a lock 3 to pass through and lock the circuit breaker lock 10. The tag 20 includes a retaining ring 21, a connector 22, and an identification plate 23. The retaining ring 21 is fitted around the outer periphery of the circuit breaker lock 10. One end of the identification plate 23 is suspended from the retaining ring 21 via the connector 22. A warning label 231 is provided on the front of the identification plate 23.

[0037] Normally, when performing relay protection or equipment maintenance, it is necessary to disconnect the circuit breaker 2, that is, to adjust the disconnect switch 2a of the circuit breaker 2 to the disconnect position. The disconnect switch 2a can switch between the disconnect position and the open position along the first rotation direction X. The circuit breaker 2 is provided with multiple spaced locking seats 2b, and the locking seats 2b are provided with locking holes 2c.

[0038] In some embodiments, the circuit breaker lock 10 includes an operating part 13, a circuit breaker lock body 11, and two locking hooks 14. The two locking hooks 14 are arranged opposite to each other. The operating part 13 is movably connected to one end of the circuit breaker lock body 11, one end of the locking hook 14 is connected to the operating part 13, and the other end of the locking hook 14 extends out from the end of the circuit breaker lock body 11 away from the operating part 13.

[0039] The following describes the process of the circuit breaker lock 10 engaging with the lock base 2b: After the disconnect switch 2a is in the open position, the circuit breaker lock 10 is placed between two adjacent lock seats 2b. The operating part 13 is pushed away from the circuit breaker lock body 11, so that the operating part 13 is in the unpressed state. This causes both locking hooks 14 to retract into the circuit breaker lock body 11 in the direction close to the operating part 13, and the two locking hooks 14 to move away from each other. This allows one locking hook 14 to extend into the locking hole 2c of one lock seat 2b, and the other locking hook 14 to extend into the locking hole 2c of the other lock seat 2b, thereby enabling the circuit breaker lock 10 to engage with the lock seat 2b. At this time, the circuit breaker lock body 11 abuts against the disconnect switch 2a, preventing the disconnect switch 2a from rotating from the open position to the open position in the first rotation direction X.

[0040] The following describes the process of circuit breaker lock 10 separating from lock base 2b: With the disconnect switch 2a in the open position, push the operating part 13 towards the circuit breaker lock body 11, causing the operating part 13 to be in the pressed state. This causes both locking hooks 14 to extend out of the circuit breaker lock body 11 away from the operating part 13, and the two locking hooks 14 to move closer to each other. This causes one locking hook 14 to disengage from the locking hole 2c of one lock seat 2b, and the other locking hook 14 to disengage from the locking hole 2c of the other lock seat 2b, thereby separating the circuit breaker lock 10 from the lock seat 2b. Remove the circuit breaker lock 10 from between the two adjacent lock seats 2b. At this point, the circuit breaker lock body 11 and the disconnect switch 2a are no longer in contact, and the disconnect switch 2a can rotate from the open position to the open position along the first rotation direction X.

[0041] It should be noted that the circuit breaker lock 10 may be relatively small, and the operating part 13 may only be operated with one hand. Therefore, the circuit breaker lock 10 also includes a flange 12, which protrudes from the outer periphery of the circuit breaker lock body 11. When operating with one hand, the operating part 13 can be pushed by pressing the fingers against the flange 12, which facilitates operation.

[0042] Furthermore, after the circuit breaker lock 10 is engaged with the lock seat 2b, in order to reduce the risk that the circuit breaker lock may separate from the lock seat 2b due to the operation part 13 moving along the path close to the circuit breaker lock body 11, the operation part 13 may be provided with a lock hole 15, and the lock 3 may be locked in the lock hole 15 to prevent the operation part 13 from moving along the path close to the circuit breaker lock body 11.

[0043] In some embodiments, the retaining ring 21 may be made of metal, plastic, rubber, etc.

[0044] In some embodiments, the retaining ring 21 can be first fitted onto the circuit breaker lock 10, and then the circuit breaker lock 10 can be engaged with the circuit breaker 2.

[0045] In some embodiments, the circuit breaker lock 10 can be engaged with the circuit breaker 2 first, and then the retaining ring 21 can be fitted onto the circuit breaker lock 10. For example, the retaining ring 21 can have an opening 212, through which it is fitted onto the circuit breaker lock 10. The retaining ring 21 can have a certain elasticity, undergoing elastic deformation during fitting and elastically returning to its original position after fitting. Alternatively, the retaining ring 21 can have two ends that are detachably connected. During fitting, the two ends of the retaining ring 21 are separated, and after fitting, the two ends are connected, thereby fitting the retaining ring 21 onto the circuit breaker lock 10.

[0046] In some embodiments, the connector 22 may be made of metal, plastic, or the like.

[0047] In some embodiments, the sign 23 may be made of metal, plastic, or the like.

[0048] In some embodiments, the sign 23 may have a front and a back in its thickness direction.

[0049] In some embodiments, the warning label 231 may be a scratch, solder mark, coating, etc.

[0050] In some embodiments, the warning sign 231 may be integrally formed with the sign 23, or it may be processed after the sign 23 leaves the factory.

[0051] In some embodiments, warning sign 231 may be "Personnel are working, do not turn on the switch".

[0052] In some embodiments, the connector 22 can be connected to the retaining ring 21 by welding, bolting, or snap-fitting, and the connector 22 can be connected to the sign 23 by welding, bolting, or snap-fitting.

[0053] The technical solution of this application embodiment prevents the circuit breaker 2 from closing by using the circuit breaker lock 10, thereby preventing other personnel from accidentally closing the circuit breaker 2, reducing the risk of electric shock to operators, equipment damage, and power grid accidents, and improving safety. Simultaneously, by setting up an identification sign 23 with a hanging tag 20, clear visual warning information is provided, informing all personnel that the equipment is in a prohibited operation state, reducing the risk of other personnel accidentally closing the circuit breaker 2. Furthermore, by using a retaining ring 21 fitted around the outer periphery of the circuit breaker lock 10, and using a connector 22 to suspend the identification sign 23 from the retaining ring 21, the reliability and convenience of suspending the identification sign 23 are improved.

[0054] Please refer to Figure 5 and refer to Figure 6 , Figure 6 This is a schematic diagram of a hang tag provided in some embodiments of this application. In some embodiments, the circuit breaker lock 10 includes a circuit breaker lock body 11 and a flange portion 12, the flange portion 12 protruding from the outer peripheral surface of the circuit breaker lock body 11, and a retaining ring 21 sleeved on the outer periphery of the flange portion 12.

[0055] In some embodiments, the shape of the retaining ring 21 and the shape of the flange 12 can be adapted.

[0056] In some embodiments, the flange portion 12 can be a disk, the retaining ring 21 can be a ring, and the inner circumferential surface of the retaining ring 21 can be fitted onto the outer circumferential surface of the flange portion 12.

[0057] The technical solution of this application embodiment, by fitting the retaining ring 21 onto the flange portion 12 of the circuit breaker lock 10, helps to improve the reliability and convenience of the hanging sign 23.

[0058] Please refer to Figure 6 and refer to Figure 7 , Figure 7 This is a schematic diagram of a retaining ring provided in some embodiments of this application. In some embodiments, the inner circumferential surface of the retaining ring 21 is provided with a groove 211, and the outer circumference of the flange portion 12 is embedded in the groove 211.

[0059] In some embodiments, the inner circumferential surface of the retaining ring 21 is provided with a groove 211. The groove 211 can be integrally formed with the retaining ring 21 or machined on the inner circumferential surface of the retaining ring 21.

[0060] In some embodiments, the flange 12 can be a disk, and the inner wall of the groove 211 can be an arc surface adapted to the flange 12. When the outer periphery of the flange 12 is inserted into the groove 211, the inner wall of the groove 211 covers part of the outer periphery of the flange 12, reducing the axial displacement of the retaining ring 21 from the flange 12.

[0061] The technical solution of this application embodiment, by embedding the outer periphery of the flange portion 12 into the groove 211 on the inner periphery surface of the retaining ring 21, helps to reduce the risk of the retaining ring 21 detaching from the flange portion 12 and improves the reliability of the hanging sign 23.

[0062] Please refer to Figure 6 and Figure 7 In some embodiments, the retaining ring 21 is an opening 212 ring.

[0063] In some embodiments, the retaining ring 21 is an open ring 212, that is, the retaining ring 21 has an open ring 212. The open ring 212 can be formed integrally with the retaining ring 21 or can be formed by machining.

[0064] In some embodiments, the circuit breaker lock 10 can be engaged with the circuit breaker 2 first, and then the retaining ring 21 can be fitted onto the circuit breaker lock 10. The retaining ring 21 can have a certain elasticity. When fitted, the retaining ring 21 undergoes elastic deformation, causing the opening 212 of the retaining ring 21 to be opened by the flange portion 12, thereby expanding the opening 212. After fitting, the flange portion 12 no longer expands the opening 212, and the retaining ring 21 elastically resets, thereby resetting the opening 212, so that the flange portion 12 is engaged within the retaining ring 21.

[0065] Similarly, when the retaining ring 21 is removed, the retaining ring 21 undergoes elastic deformation, causing the opening 212 of the retaining ring 21 to be opened by the flange portion 12, thereby expanding the opening 212. After the retaining ring 21 separates from the flange portion 12, the flange portion 12 no longer opens the opening 212, and the retaining ring 21 elastically resets, thereby resetting the opening 212.

[0066] The technical solution of this application embodiment, by setting the retaining ring 21 as an open ring 212, allows the circuit breaker lock 10 to still be fitted onto the flange portion 12 of the circuit breaker lock 10 and removed from the flange portion 12 of the circuit breaker lock 10 after it is installed on the circuit breaker 2, which helps to improve the convenience of installing and removing the retaining ring 21.

[0067] Please refer to Figure 6 and Figure 7 In some embodiments, the central angle corresponding to the opening 212 of the retaining ring 21 is α, which satisfies: 45°≤α≤90°.

[0068] In some embodiments, the central angle α satisfies the above conditions, and α can be any value among 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, and 90°, or a value between any two values.

[0069] It should be noted that due to processing errors and the incomplete reset process after expansion of opening 212, the central angle α corresponding to opening 212 may exceed 90°.

[0070] In some embodiments, the central angle α corresponding to the opening 212 satisfies the above conditions, and the opening 212 is in the state when it is not fitted onto the flange portion 12.

[0071] In some embodiments, the retaining ring 21 may have a first end and a second end along its circumference, with the first end and the second end spaced apart to form an opening 212 between the first end and the second end. The orthographic projection of the retaining ring 21 is obtained with its axial direction as the projection direction. Connecting the center of the orthographic projection of the first end with the center of the orthographic projection of the retaining ring 21 yields a first straight line; connecting the center of the orthographic projection of the second end with the center of the orthographic projection of the retaining ring 21 yields a second straight line. The angle between the first straight line and the second straight line is the central angle α corresponding to the opening 212.

[0072] In the technical solution of this application embodiment, when the retaining ring 21 is fitted onto the flange portion 12 of the circuit breaker lock 10 or removed from the flange portion 12 of the circuit breaker lock 10, the retaining ring 21 can undergo elastic deformation, causing the opening 212 to expand. After being fitted onto or removed from the flange portion 12 of the circuit breaker lock 10, the retaining ring 21 can elastically return to its original position, causing the opening 212 to return to its original position. The central angle α corresponding to the opening 212 of the retaining ring 21 satisfies the above conditions. When α ≥ 45°, the opening 212 is easy to expand, thereby improving the convenience of installation and disassembly; when α ≤ 90°, the opening 212 elastically returns to its original position after expansion, which helps to improve the reliability of the retaining ring 21 fitted onto the circuit breaker lock 10.

[0073] Please refer to Figure 5 and refer to Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of a hang tag provided in other embodiments of this application. Figure 9 This is a schematic diagram of a retaining ring provided in some other embodiments of this application. In some embodiments, the circuit breaker lock 10 includes a circuit breaker lock body 11 and a flange portion 12, the flange portion 12 protruding from the outer peripheral surface of the circuit breaker lock body 11, and the retaining ring 21 sleeved on the outer periphery of the circuit breaker lock body 11.

[0074] In some embodiments, the retaining ring 21 can be a closed ring-shaped member. The retaining ring 21 can be first fitted onto the outer periphery of the circuit breaker lock body 11, and then the circuit breaker lock 10 can be engaged with the circuit breaker 2.

[0075] In some embodiments, the shape of the inner periphery of the retaining ring 21 may match the shape of the outer periphery of the circuit breaker lock body 11.

[0076] In some embodiments, the retaining ring 21 can be completely fitted around the outer periphery of the circuit breaker lock body 11, and the inner circumferential surface of the retaining ring 21 is interference-fitted with the outer periphery of the circuit breaker lock body 11, reducing the risk of interference with the circuit breaker 2 caused by the movement of the retaining ring 21 on the circuit breaker lock body 11.

[0077] The technical solution of this application embodiment, by using a retaining ring 21 fitted onto the circuit breaker lock body 11 of the circuit breaker lock 10, helps to improve the reliability and convenience of the hanging sign 23.

[0078] Please refer to Figure 8 and Figure 9 In some embodiments, the inner circumferential surface of the retaining ring 21 is provided with a protrusion 213, which abuts against the outer circumference of the circuit breaker lock body 11.

[0079] In some embodiments, the inner circumferential surface of the retaining ring 21 is provided with a protrusion 213. The protrusion 213 can be integrally formed with the retaining ring 21, or it can be provided on the inner circumferential surface of the retaining ring 21 by welding, gluing or bolting.

[0080] In some embodiments, when the retaining ring 21 is fitted onto the outer periphery of the circuit breaker lock body 11, the protrusion 213 can abut against the outer periphery of the circuit breaker lock body 11, reducing the risk of the retaining ring 21 moving on the circuit breaker lock body 11 and interfering with the circuit breaker 2.

[0081] In some embodiments, the number of protrusions 213 can be multiple, and multiple protrusions 213 together abut against the outer periphery of the circuit breaker lock body 11.

[0082] In some embodiments, the number of protrusions 213 can be two, with the two protrusions 213 arranged radially opposite to each other along the retaining ring 21, and the two protrusions 213 jointly abutting against the outer periphery of the circuit breaker lock body 11.

[0083] In some embodiments, the number of protrusions 213 can be one, and the inner peripheral surfaces of protrusions 213 and retaining ring 21 abut against the outer periphery of circuit breaker lock body 11.

[0084] The technical solution of this application embodiment provides a protrusion 213 on the inner circumferential surface of the retaining ring 21. The protrusion 213 abuts against the outer circumference of the circuit breaker lock body 11, which helps to improve the reliability of the retaining ring 21 being fitted onto the circuit breaker lock 10.

[0085] Please refer to Figure 3 , Figure 4 , Figure 8 and Figure 9In some embodiments, along the circumferential direction of the circuit breaker lock body 11, the outer circumferential surface of the circuit breaker lock body 11 includes a first flat surface 111, a first arc surface 112, a second flat surface 113, and a second arc surface 114 connected end to end. Along the circumferential direction of the retaining ring 21, the inner circumferential surface of the retaining ring 21 includes a third flat surface 214, a third arc surface 215, a fourth flat surface 216, and a fourth arc surface 217 connected end to end. Both the third flat surface 214 and the fourth flat surface 216 are provided with protrusions 213. The protrusions 213 on the third flat surface 214 abut against the first flat surface 111, and the protrusions 213 on the fourth flat surface 216 abut against the second flat surface 113.

[0086] In some embodiments, the circuit breaker lock body 11 can be directly injection molded to form a first flat surface 111, a first arc surface 112, a second flat surface 113, and a second arc surface 114 connected end to end.

[0087] In some embodiments, the circuit breaker lock body 11 can be a cylinder. After injection molding, it is machined to form a first flat surface 111 and a second flat surface 113 on the outer periphery of the circuit breaker lock body 11, while the outer periphery of the cylinder is divided into a first arc surface 112 and a second arc surface 114.

[0088] In some embodiments, the first flat surface 111 and the second flat surface 113 may be arranged opposite each other along the radial direction of the circuit breaker lock body 11.

[0089] In some embodiments, along the circumferential direction of the circuit breaker lock body 11, one end of the first flat surface 111 is connected to one end of the first arc surface 112, the other end of the first arc surface 112 is connected to one end of the second flat surface 113, the other end of the second flat surface 113 is connected to one end of the second arc surface 114, and the other end of the second arc surface 114 is connected to the end of the first flat surface 111 that is away from the first arc surface 112.

[0090] In some embodiments, the retaining ring 21 can be directly injection molded to form a third flat surface 214, a third arc surface 215, and a third flat surface 214 and a third arc surface 215 connected end to end.

[0091] In some embodiments, the retaining ring 21 can be a circular ring. After injection molding, the retaining ring 21 is machined to form a third flat surface 214 and a fourth flat surface 216 on its inner circumferential surface, while the inner circumferential surface of the retaining ring 21 is separated into a third arc surface 215 and a fourth arc surface 217.

[0092] In some embodiments, along the circumference of the retaining ring 21, one end of the third flat surface 214 is connected to one end of the third arc surface 215, the other end of the third arc surface 215 is connected to one end of the fourth flat surface 216, the other end of the fourth flat surface 216 is connected to one end of the fourth arc surface 217, and the other end of the fourth arc surface 217 is connected to the end of the third flat surface 214 opposite to the third arc surface 215.

[0093] In some embodiments, there are two bumps 213, one bump 213 is disposed on the third flat surface 214, and the other bump 213 is disposed on the fourth flat surface 216.

[0094] In some embodiments, when the retaining ring 21 is sleeved on the circuit breaker lock body 11, the protrusion 213 provided on the third flat surface 214 abuts against the first flat surface 111, the protrusion 213 provided on the fourth flat surface 216 abuts against the second flat surface 113, the third arc surface 215 abuts against the first arc surface 112, and the fourth arc surface 217 abuts against the second arc surface 114.

[0095] The technical solution of this application embodiment is that the protrusion 213 on the third flat surface 214 abuts against the first flat surface 111, and the protrusion 213 on the fourth flat surface 216 abuts against the second flat surface 113, which helps to improve the reliability of the retaining ring 21 being sleeved on the circuit breaker lock 10.

[0096] Please refer to Figure 7 and Figure 9 and refer to Figure 10 , Figure 10 This is a schematic diagram of a connector provided in some embodiments of this application. In some embodiments, the retaining ring 21 is provided with a first mounting base 218 and a second mounting base 219, which are disposed opposite to each other. The first mounting base 218 is provided with a first connecting hole 2181, and the second mounting base 219 is provided with a second connecting hole 2191. The connector 22 includes an intermediate section 221, a first connecting section 222, a second connecting section 223, a first end section 224, and a second end section 225. The back of the sign 23 is provided with a hook 232, which is connected to the intermediate section 221. One end of the intermediate section 221 is connected to the first end section 224 through the first connecting section 222, and the other end of the intermediate section 221 is connected to the second end section 225 through the second connecting section 223. The first end section 224 is inserted into the first connecting hole 2181, and the second end section 225 is inserted into the second connecting hole 2191. The first connecting segment 222 and the second connecting segment 223 are bent relative to the middle segment 221, the first end segment 224 is bent relative to the first connecting segment 222, and the second end segment 225 is bent relative to the second connecting segment 223.

[0097] In some embodiments, the retaining ring 21 is provided with a first mounting seat 218 and a second mounting seat 219. The first mounting seat 218 and the second mounting seat 219 can be disposed on the outer peripheral surface of the retaining ring 21 or on the axial surface of the retaining ring 21.

[0098] In some embodiments, the first mounting base 218 may be integrally formed with the retaining ring 21, or it may be connected to the retaining ring 21 by means of adhesive bonding, welding or bolt connection.

[0099] In some embodiments, the second mounting base 219 may be integrally formed with the retaining ring 21, or it may be connected to the retaining ring 21 by means of adhesive bonding, welding or bolting.

[0100] In some embodiments, the form in which the first mounting base 218 is disposed on the retaining ring 21 and the form in which the second mounting base 219 is disposed on the retaining ring 21 may be the same or different.

[0101] In some embodiments, the first mounting base 218 and the second mounting base 219 may be spaced apart along the circumference of the retaining ring 21.

[0102] In some embodiments, the first mounting base 218 is provided with a first connecting hole 2181, which can be formed by integral molding or machining.

[0103] In some embodiments, the second mounting base 219 is provided with a second connecting hole 2191, which can be formed by integral molding or machining.

[0104] In some embodiments, the forming method of the first connecting hole 2181 and the forming method of the second connecting hole 2191 may be the same or different.

[0105] It should be noted that if the first mounting base 218 and the second mounting base 219 are located above the retaining ring 21, it is inconvenient to connect the connecting piece 22, and it is easy for the sign 23 to sag under gravity and interfere with the retaining ring 21. Therefore, the first mounting base 218 and the second mounting base 219 need to be located below the retaining ring 21. When the retaining ring 21 is a closed ring, in order to reduce the impact after the retaining ring 21 is fitted onto the circuit breaker lock 10, the first mounting base 218 and the second mounting base 219 are located above the retaining ring 21. The number of first mounting bases 218 and the number of second mounting bases 219 can both be two. The two first mounting bases 218 are arranged radially opposite each other along the retaining ring 21, and the two second mounting bases 219 are arranged radially opposite each other along the retaining ring 21, so that there is always one first mounting base 218 and one second mounting base 219 located below the retaining ring 21.

[0106] In some embodiments, the connector 22 includes an intermediate section 221, a first connecting section 222, a second connecting section 223, a first end section 224, and a second end section 225. The connector 22 may be integrally formed or formed by welding several connecting sections.

[0107] In some embodiments, the connector 22 can be a straight connecting segment, which is formed by bending into an intermediate segment 221, a first connecting segment 222, a second connecting segment 223, a first end segment 224, and a second end segment 225.

[0108] In some embodiments, the material of the connector 22 may be metal, plastic, etc., and the connector 22 may have the ability to elastically deform and elastically return to its original position.

[0109] In some embodiments, the hook 232 may be disposed on the back of the sign 23, that is, the hook 232 is disposed on the surface of the sign 23 where the warning sign 231 is not provided, thereby reducing the risk of the hook 232 obscuring the warning sign 231.

[0110] In some embodiments, when the connector 22 connects the retaining ring 21 and the sign 23, the middle section 221 can be connected to the hook 232 first, and then the first end section 224 and the second end section 225 can be pressed simultaneously, causing the first end section 224 and the second end section 225 to elastically deform and move closer to each other, thereby bringing the first connecting section 222 and the second connecting section 223 closer to each other. At this time, the first connecting section 222 and the second connecting section 223 can both be disposed between the first mounting base 218 and the second mounting base 219, such that the end of the first connecting section 222 facing the second mounting base 219 is inserted into the first connecting hole 2181, and the end of the second connecting section 223 facing the first mounting base 218 is inserted into the second connecting hole 2191. Release the first end segment 224 and the second end segment 225 so that the first end segment 224 and the second end segment 225 elastically reset and move away from each other. At this time, the first connecting segment 222 passes through the end of the first connecting hole 2181 away from the second mounting base 219, and the second connecting segment 223 passes through the end of the second connecting hole 2191 away from the first mounting base 218, so that the connector 22 connects the retaining ring 21 and the sign 23.

[0111] In some embodiments, when the connector 22 separates the retaining ring 21 and the sign 23, the middle section 221 can be first removed from the hook 232. Then, the first end section 224 and the second end section 225 are pressed simultaneously, causing the first end section 224 and the second end section 225 to elastically deform and move closer to each other, thereby bringing the first connecting section 222 and the second connecting section 223 closer to each other. At this time, the first connecting section 222 exits the first connecting hole 2181 from the end facing the second mounting base 219, and the second connecting section 223 exits the second connecting hole 2191 from the end facing the first mounting base 218. Then, the first connecting section 222 and the second connecting section 223 are removed from between the first mounting base 218 and the second mounting base 219, and the first end section 224 and the second end section 225 are released, causing the first end section 224 and the second end section 225 to elastically reset and move away from each other, thus separating the retaining ring 21 and the sign 23 by the connector 22.

[0112] It should be noted that, in order to improve the reliability of the connector 22 connecting the retaining ring 21, when the first connecting segment 222 protrudes from the end of the first connecting hole 2181 away from the second mounting base 219, and the second connecting segment 223 protrudes from the end of the second connecting hole 2191 away from the first mounting base 218, the protruding part of the first connecting segment 222 can be bent so that the bent part abuts against the surface of the first mounting base 218 away from the second mounting base 219, reducing the risk of the first connecting segment 222 exiting the first connecting hole 2181, and the protruding part of the second connecting segment 223 can be bent so that the bent part abuts against the surface of the second mounting base 219 away from the first mounting base 218, reducing the risk of the second connecting segment 223 exiting the second connecting hole 2191.

[0113] The technical solution of this application embodiment connects the retaining ring 21 through the first end segment 224 and the second end segment 225 of the connector 22, and connects the hook 232 through the middle segment 221 of the connector 22, which helps to improve the convenience of connecting the retaining ring 21 and the tag 20 through the connector 22.

[0114] Please refer to Figure 10 and refer to Figure 11 , Figure 11 This is a schematic diagram illustrating the interaction between a hook and a tag according to some embodiments of this application. In some embodiments, the tag 20 further includes a limiting pin 24, and the hook 232 is provided with a limiting hole 2321, which penetrates the inner and outer sides of the hook 232. The limiting pin 24 passes through the limiting hole 2321 and is used to prevent the hook 232 from detaching from the middle section 221.

[0115] In some embodiments, a hook 232 is disposed on the back of the sign 23, and one end of the hook 232 is connected to the sign 23. The connection method can be welding, gluing, or bolting.

[0116] In some embodiments, the hook 232 may be integrally formed with the sign 23.

[0117] In some embodiments, the other end of the hook 232 may be spaced apart from the sign 23, and the hook 232 and the sign 23 may form a receiving cavity. The middle section 221 may enter the receiving cavity from between the other end of the hook 232 and the sign 23. Under the action of gravity, the sign 23 droops, causing the upper surface of the middle section 221 to abut against the hook 232.

[0118] In some embodiments, the surface of the hook 232 facing the signboard 23 is the inner side, and the surface of the hook 232 away from the signboard 23 is the outer side. The limiting hole 2321 penetrates both the inner and outer sides. When the upper surface of the intermediate section 221 abuts against the hook 232, the limiting pin 24 passes through the limiting hole 2321, so that the limiting pin 24 is located at the lower end of the intermediate section 221, thereby preventing the hook 232 from detaching from the intermediate section 221.

[0119] The technical solution of this application embodiment prevents the hook 232 from detaching from the middle section 221 by setting a limit pin 24, which helps to improve the reliability of the connector 22 connecting the tag 20.
