[0036] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0037] Embodiment one

[0038] The present embodiment provides an operating mechanism 100 of circuit breaker accessory, please refer to Figures 1-7 , including a support frame 3, an active control unit 2 and a driven regulating unit 1, wherein the active control unit 2 includes a sleeve 20, a coil 25, an action rod 19 and a conduction connecting element 15, the sleeve 20 is connected with the support frame 3, the coil 25 is wound on the outside of the sleeve 20, the coil 25 can be electrically connected with an external circuit, the action rod 19 is slidingly arranged in the sleeve 20, and the action rod 19 is made of a magnetically conductive material; when the external circuit fails, the current in the coil 25 increases, and under the action of the magnetic field, the action rod 19 can move along the axial direction of the coil 25; the conduction connecting element 15 is connected with the support frame 3; the driven regulating unit 1 includes a regulating assembly 4, the regulating assembly 4 includes a linkage element and a conductive piece 14, the linkage element is connected with the action rod 19, the linkage element can drive the conductive piece 14 to move, so that the conductive piece 14 abuts against or separates from the conduction connecting element 15, to achieve the purpose of conduction and disconnection.

[0039] The operating mechanism 100 of the circuit breaker accessory of the present application, the support frame 3 provides stable support for the active control unit 2 and the driven adjustment unit 1, the coil 25 arranged outside the sleeve 20 is connected with the external circuit, when the external circuit fails, the current in the coil 25 increases, under the action of the magnetic field, the action rod 19 moves along the axis direction of the coil 25, the action rod 19 drives the conductive sheet 14 to move, so that the conductive sheet 14 is separated from the conduction connecting element 15, realizing the circuit breaking control operation. After the external circuit failure is repaired, the action rod 19 resets, and the conductive sheet 14 abuts against the conduction connecting element 15 to realize conduction. The operating mechanism 100 of the circuit breaker accessory of the present application, the active control unit 2 drives the driven adjustment unit 1 to move synchronously, realizing the purpose of linear adjustment, simplifying the structure of the operating mechanism, and improving the circuit adjustment efficiency of the circuit breaker accessory.

[0040] In the specific embodiment, the support frame 3 adopts a frame structure, which reduces the occupied space of the operating mechanism, and is beneficial to reducing the weight of the operating mechanism. While providing support for the active control unit 2 and the driven adjustment unit 1, the structure of the operating mechanism is further simplified, and the flexible adaptability of the operating mechanism is improved.

[0041] Specifically, the active control unit 2 further includes a first limiting insulating block 18, a second limiting insulating block 21, and an adaptive slot block 17. The first limiting insulating block 18 and the second limiting insulating block 21 are respectively arranged at two ends of the sleeve 20 and connected with the support frame 3. The adaptive slot block 17 is slidably connected with the action rod 19 through the first limiting insulating block 18. The conduction connecting element 15 is arranged on the side of the second limiting insulating block 21 away from the sleeve 20. The first limiting insulating block 18 and the second limiting insulating block 21 provide stable support for the sleeve 20, ensuring the structural stability of the active control unit 2, and limiting the coil 25 arranged outside the sleeve 20. In the specific embodiment, the side of the first limiting insulating block 18 and the second limiting insulating block 21 facing the sleeve 20 is provided with a plug connector matched with the sleeve 20. The first limiting insulating block 18 and the second limiting insulating block 21 are connected with the sleeve 20 through the plug connector, improving the disassembly and assembly convenience and the structural stability of the active control unit 2. The adaptive slot block 17 is slidably connected with the action rod 19 through the first limiting insulating block 18. The action rod 19 drives the linkage element to act through the adaptive slot block 17, so as to drive the driven adjustment unit 1 to move synchronously to adjust the circuit, improving the adjustment efficiency.

[0042] The active control unit 2 further comprises a first elastic member arranged in the sleeve 20 to enable the action lever 19 to reset after the magnetic field disappears. After the external circuit is repaired, the action lever 19 can be reset smoothly under the elastic force of the first elastic member, thereby driving the adaptive slot block 17 and the linkage element to reset, enabling the conductive sheet 14 to re-abut against the conduction connecting element 15 to conduct electricity and realize the regulating function of the circuit breaker accessory, thereby ensuring the working reliability of the circuit system.

[0043] More specifically, the linkage element comprises a first connecting rod 10 and a second connecting rod 11, both of which are connected with the conductive sheet 14, and the adaptive slot block 17 can drive the first connecting rod 10 and the second connecting rod 11 to move, thereby driving the conductive sheet 14 to move. The movement direction of the first connecting rod 10 and the second connecting rod 11 is parallel to the movement direction of the action lever 19. The driven regulating unit 1 drives the conductive sheet 14 to reciprocate by means of the first connecting rod 10 and the second connecting rod 11, thereby realizing the contact and separation of the conductive sheet 14 and the conduction connecting element 15 to regulate the circuit. The first connecting rod 10 is parallel to the second connecting rod 11, and the adaptive slot block 17 drives the first connecting rod 10 and the second connecting rod 11 to move, thereby realizing the purpose of driving the conductive sheet 14 to move along the axis direction parallel to the coil 25, and the structure is simple and the movement is reliable.

[0044] Meanwhile, the linkage element further comprises a connecting guide rod 5, a push block 6 and a pressing frame 7. One end of the connecting guide rod 5 is connected with the adaptive slot block 17, and the other end of the connecting guide rod 5 is connected with one end of the first connecting rod 10 away from the conductive sheet 14. The connecting guide rod 5 is further connected with the push block 6, which is located between the adaptive slot block 17 and the first connecting rod 10. The push block 6 is slidably connected with the support frame 3, and the sliding direction of the push block 6 is parallel to the movement direction of the action lever 19. The pressing frame 7 is connected with the push block 6, and further connected with one end of the second connecting rod 11 away from the conductive sheet 14. When the adaptive slot block 17 moves towards the second limiting insulating block 21 along with the action lever 19, the connecting guide rod 5 is driven to move synchronously, the first connecting rod 10 is driven to move by the connecting guide rod 5, the first connecting rod 10 pushes the conductive sheet 14 to separate from the conduction connecting element 15, thereby realizing the breaking control operation. Meanwhile, the connecting guide rod 5 is further connected with the push block 6, and the push block 6 is driven to move by the connecting guide rod 5 when the connecting guide rod 5 moves along with the action lever 19. The push block 6 slides relative to the support frame 3, and drives the second connecting rod 11 to move by means of the pressing frame 7, thereby avoiding the influence of the second connecting rod 11 on the movement of the conductive sheet 14. When the circuit is regulated to be conductive, the pressing frame 7 is pulled, the second connecting rod 11 drives the conductive sheet 14 to move towards the first limiting insulating block 18, thereby enabling the conductive sheet 14 to abut against the conduction connecting element 15 to realize the conduction regulating control.

[0045] In the specific embodiment, the push block 6 is connected with the support frame 3 by the support block 26, which provides stable support for the push block 6, thereby improving the structural and motion stability of the linkage element. One end of the support block 26 is connected with the push block 6, and the other end of the support block 26 is slidably connected with the support frame 3. A second elastic member is arranged between the support block 26 and the support frame 3 to enable the support block 26 to reset. The support block 26 is slidably connected with the support frame 3 to avoid affecting the motion of the push block 6 and ensure the working reliability of the linkage element.

[0046] Further, the adjusting assembly 4 further comprises an adjusting piece 12 and a limiting block 9. One end of the adjusting piece 12 is connected with the conductive piece 14, and the other end of the adjusting piece 12 is connected with the first connecting rod 10. The adjusting piece 12 is further connected with the second connecting rod 11 by the adapter frame 13, and the first connecting rod 10 and the adapter frame 13 are respectively located on two sides of the adjusting piece 12. The adjusting piece 12 is arranged to facilitate the connection of the first connecting rod 10 and the second connecting rod 11 with the conductive piece 14, so that the first connecting rod 10 and the second connecting rod 11 can smoothly drive the conductive piece 14 to move. The adjusting piece 12 can be made of insulating material to ensure the reliable movement of the conductive piece 14 and improve the operation safety factor.

[0047] In order to provide stable support for the first connecting rod 10, the limiting block 9 is connected with the support frame 3, and the first connecting rod 10 is slidably connected with the limiting block 9. The first connecting rod 10 is slidably connected with the limiting block 9 without affecting the reciprocating motion of the first connecting rod 10, thereby enhancing the support effect of the first connecting rod 10 and further improving the motion stability of the first connecting rod 10, and thus improving the action reliability of the linkage element. In the specific embodiment, the limiting block 9 has a sliding hole matched with the first connecting rod 10, and the first connecting rod 10 is slidably connected with the adjusting piece 12 after passing through the sliding hole. Meanwhile, a third elastic member 8 is arranged between the limiting block 9 and the connecting guide rod 5 to enable the first connecting rod 10 to smoothly reset, thereby ensuring the working reliability of the driven adjusting unit 1. In actual application, the third elastic member 8 can be a spring, which is sleeved outside the first connecting rod 10 and located between the limiting block 9 and the connecting guide rod 5. The structure is compact and easy to install.

[0048] In addition, it needs to be explained that the operating mechanism 100 of the circuit breaker accessory of the present application further comprises a limiting protection assembly 16, which comprises a fixed support block 22, an operating seat 23 and a swing limiting rod 24, the fixed support block 22 is connected with the support frame 3, one end of the operating seat 23 is connected with the fixed support block 22, the other end of the operating seat 23 is hinged with the swing limiting rod 24 and a torsion spring is arranged between the two, the swing limiting rod 24 can abut against the adjusting piece 12 to limit the position of the adjusting piece 12. The arrangement of the limiting protection assembly 16 can prevent the automatic reset of the conducting piece 14. When the adjusting piece 12 moves with the first connecting rod 10 and the second connecting rod 11, it will push the swing limiting rod 24, the swing limiting rod 24 rotates relative to the operating seat 23, so that the adjusting piece 12 can continue to move. Specifically, when the circuit breaking operation is performed, the first connecting rod 10 drives the adjusting piece 12 to move away from the second limiting insulating block 21, the adjusting piece 12 pushes the swing limiting rod 24, the swing limiting rod 24 rotates relative to the operating seat 23, the adjusting piece 12 continues to move after “passing” the swing limiting rod 24, the adjusting piece 12 smoothly separates from the conducting connecting element 15, after the adjusting piece 12 “passes” the swing limiting rod 24, the swing limiting rod 24 is reset under the action of the torsion spring, limiting the reverse movement of the adjusting piece 12, avoiding the automatic reset of the adjusting piece 12 after the external circuit fault is repaired. When the conducting piece 14 and the conducting connecting element 15 need to be reconnected, pull the pressing frame 7, so that the second connecting rod 11 drives the adjusting piece 12 to move towards the first limiting insulating block 18, the adjusting piece 12 is pressed against the swing limiting rod 24 under the action of the pulling force, so that the swing limiting rod 24 reverses in the opposite direction (here, the “opposite direction” refers to the reverse direction of the swing limiting rod 24 during the circuit breaking operation), the adjusting piece 12 continues to move after “passing” the swing limiting rod 24 again, until the conducting piece 14 contacts the conducting connecting element 15 to realize conduction, after the swing limiting rod 24 is separated from the adjusting piece 12, the swing limiting rod 24 is reset under the action of the torsion spring, ready for the next limiting. The present application sets the limiting protection assembly 16, which can effectively prevent the direct reset of the conducting piece 14 to cause safety accidents, thereby improving the adjustment safety factor of the operating mechanism. It needs to be explained here that in actual application, the pulling force of the pressing frame 7 can be the force applied to the operating mechanism by external equipment or other mechanisms of the circuit breaker system, which can be selected and adjusted according to the actual working condition of the circuit breaker system, and the external force applying equipment is reasonably selected or the force is directly applied by the operator to achieve the purpose of pulling the pressing frame 7, which is a common means for those skilled in the art, and will not be described here.

[0049] Further, in the specific embodiment, the number of adjustment assemblies 4 is two sets, and the two sets of adjustment assemblies 4 are symmetrically arranged on both sides of the active control unit 2 with the axis of the sleeve 20 as the axis of symmetry, and the arrangement of the two sets of adjustment assemblies 4 is beneficial to enhance the function realized by the circuit breaker accessory and improve the safety and operation convenience of the circuit breaker system. The symmetric arrangement of the two sets of adjustment assemblies 4 makes the operating mechanism 100 of the circuit breaker accessory of the application compact in structure and small in space occupation, which is beneficial to improve the flexible adaptability of the operating mechanism 100 of the circuit breaker accessory.

[0050] In use, the coil 25 in the active control unit 2 is connected to an external circuit through a wire, and when the circuit has a problem, a large current is generated on the coil 25 at this time, thereby generating a magnetic field through the sleeve 20 to attract the action rod 19, so that the action rod 19 drives the adaptive groove block 17 to move to the position of the second limiting insulating block 21, and the adaptive groove block 17 moves backward on the first limiting insulating block 18 (in this document, the "front" and "rear" directions specifically refer to the directions perpendicular to the paper plane in the drawings, and the direction close to the reader is the front direction, and the direction away from the reader is the rear direction). The upper end of the adaptive groove block 17 is limitedly connected to the connecting guide rod 5, and when the adaptive groove block 17 moves, the connecting guide rod 5 of the two sets of adjustment assemblies 4 moves synchronously backward, so that the push block 6 and the pressing frame 7 move synchronously. At this time, the second connecting rod 11, the third elastic member 8, and the first connecting rod 10 can move, and the adjusting piece 12 and the adaptive frame 13 are pushed to change the position, so that the conductive piece 14 moves with them. The conductive piece 14 is connected in communication with the through connection element 15 through the lapping, and at this time, the conductive piece 14 is separated from the through connection element 15 to achieve the purpose of breaking the circuit. In order to prevent automatic reset, when the adjusting piece 12 moves, it pushes the swing limiting rod 24, the swing limiting rod 24 is turned over, the adjusting piece 12 enters the rear end of the swing limiting rod 24, at this time, the swing limiting rod 24 is reset to hinder the movement of the adjusting piece 12. When reconnection is needed, the pressing frame 7 is pulled to move the second connecting rod 11, the third elastic member 8, the limiting block 9, and the first connecting rod 10, so that the adjusting piece 12, the adaptive frame 13, and the conductive piece 14 also move, the conductive piece 14 is reconnected to work, and at this time, the adjusting piece 12 can press the swing limiting rod 24 again under the action of the pressing force, so that the swing limiting rod 24 is reversely rotated and reset again, and the movement of the adjusting piece 12 is hindered again.

[0051] The adjusting assembly 4 of the present application adopts longitudinal direct connection control, can quickly adjust, and the user pulls the pressing frame 7 forward, can drive the connecting guide rod 5, the push block 6, the pressing frame 7 to move, thereby pushing the adaptive groove block 17, so that the adaptive groove block 17 resets, and the connecting guide rod 5 drives the third elastic member 8, the first connecting rod 10, the second connecting rod 11 to move, changes the position of the adjusting sheet 12, the adaptive frame 13, the conductive sheet 14, so that the conductive sheet 14 can contact the conductive connection element 15 arranged on the second limiting insulating block 21, and conductive work is carried out;

[0052] The present application is convenient for operation by the structure of the active control unit 2, the coil 25 is wound on the sleeve 20, the coil 25 is electrified, a magnetic field is generated, when short-circuiting, the magnetic field can be enhanced instantaneously, the adaptive groove block 17 is pulled back, and the adaptive groove block 17 is connected with the connecting guide rod 5, drives the connecting guide rod 5 to move backward, so that the conductive sheet 14 can be separated from the conductive connection element 15, and the circuit breaking control work is realized.

[0053] The operating mechanism 100 of the circuit breaker accessory of the present application realizes the purpose of linear adjustment by the structure of the adjusting assembly 4, reduces the intervention of redundant mechanical parts, the connecting guide rod 5 can control the third elastic member 8, the first connecting rod 10, the second connecting rod 11 to move through the push block 6 support, so that the adjusting sheet 12, the adaptive frame 13, the conductive sheet 14 are driven to adjust; when resetting, the connecting guide rod 5 can be reset by pulling the pressing frame 7 forward, and the butt joint work is facilitated, and the limiting protection assembly 16 can limit the adjusting sheet 12, when the conductive sheet 14 is in different states, the adjusting sheet 12 can limit the adjusting sheet 12, prevents the conductive sheet 14 from resetting directly, and causes a safety accident.
