Without the padlock blocking plate 7 shielding the exposure slot 81, a user can operate the operation disc 3 through the exposure slot 81.

[0054] As shown in Figures 1-3 , Figure 6 , Figure 14 , the padlock plate 6 is provided with a padlock hole 61 at one end close to the display cover 11, and the padlock plate 6 has a storage state and a padlock state, and when the padlock plate 6 is in the storage state, the padlock hole 61 is located in the outer shell 1; and when the padlock plate 6 is in the padlock state, the padlock plate 6 protrudes out of the outer shell 1, and the padlock hole 61 is exposed outside the outer shell 1.

[0055] A reset plate 110 is provided on the plastic liner 10, and a reset spring 62 is provided on the padlock plate 6. The reset spring 62 connects the padlock plate 6 and the reset plate 110. When the padlock plate 6 protrudes out of the outer shell 1, the reset spring 62 is in a stretched state. When the external force is lost, the reset spring 62 can drive the padlock plate 6 to automatically change to a retracted state.

[0056] A hook 63 is protruded from the padlock plate 6 , and one end of the reset spring 62 is engaged with the hook 63 .

[0057] The padlock plate 6 is provided with a guide groove 64 extending in the vertical direction, and the plastic liner 10 is provided with a guide portion 120 protruding through the guide groove 64. The end of the guide portion 120 is larger than the width of the guide groove 64 to prevent the guide portion 120 from detaching from the padlock plate 6.

[0058] One end of the guide groove 64 is provided with a mounting hole 641 for the guide portion 120 to pass through. When the guide portion 120 is installed, the guide portion 120 passes through the mounting hole 641 .

[0059] In this embodiment, when the circuit breaker is closed, the padlock plate 6 is necessarily in the retracted state, and when the circuit breaker is open, the padlock plate 6 may be in the retracted state or the padlocked state. Whether to padlock or not is determined by the user according to the actual situation. In order to achieve this effect, this embodiment is configured as follows:

[0060] A resisting block 65 is provided at the other end of the padlock plate 6 away from the padlock hole 61 , wherein the padlock hole 61 is close to the display cover 11 , and the resisting block 65 is away from the display cover 11 .

[0061] The abutting block 65 is rotatably arranged relative to the padlock plate 6 .

[0062] The connecting assembly 4 includes a driving motor 41, a gear set 42, a cam 43, a slider 44, and a slide rail 45. The connecting assembly 4 is used to electrically drive the switch handle 2 to work;

[0063] like Figures 5 to 9 As shown, the gear set 42 is connected to the drive motor 41 and the cam 43, and the cam 43 is connected to the gear set 42 and the slider 44. The operation of the drive motor 41 drives the gear set 42 to rotate, thereby driving the rotation of the cam 43, and the cam 43 drives the slider 44 to move. When the electric operating device 100 with an indicating function is engaged with the circuit breaker, the slider 44 is connected to the switch handle 2, and the slider 44 slides in the horizontal direction to drive the rotation of the switch handle 2. In this way, the operation of the drive motor 41 can drive the rotation of the switch handle 2.

[0064] Meanwhile, the connecting assembly 4 can connect the operation disc 3 and the switch handle 2, the operation disc 3 rotates along the axial direction to drive the switch handle 2 to move to realize the opening or closing of the circuit breaker; the implementation mode of the embodiment is that the operation disc 3 is connected with the gear set 42 and the cam 43, and the driving motor 41 has the clutch function, when not powered, the effect of driving the gear set 42 to rotate, the cam 43 to rotate and the slider 44 to move can be realized by rotating the operation disc 3.

[0065] The slider 44 is slidably arranged relative to the slide rail 45. The slide rail 45 extends along the horizontal direction, and in the embodiment, the number of slide rails 45 is two and they are arranged at intervals.

[0066] When the padlock plate 6 is in the storage state, the slider 44 can restrict the padlock plate 6 to hang in the vertical direction, and when the padlock plate 6 is locked, the padlock plate 6 restricts the slider 44 to slide to restrict the closing of the circuit breaker.

[0067] Specifically, the abutting block 65 has a first state and a second state, and in the embodiment, the first state and the second state are different angles relative to the rotation of the padlock plate 6, when the circuit breaker is closed, the padlock hole 61 is located in the housing 1, that is, in the storage state, the abutting block 65 is in the first state, and the abutting block 65 abuts with the slider 44 in the vertical direction to restrict the padlock plate 6 to move in the vertical direction; when the circuit breaker is opened and the padlock plate 6 protrudes out of the housing 1 to be locked, that is, in the locked state, the slider 44 moves in the horizontal direction to give way to the abutting block 65, the abutting block 65 is in the second state, and the abutting block 65 abuts with the slider 44 in the horizontal direction to restrict the slider 44 to move in the horizontal direction.

[0068] The abutting block 65 is provided with a torsional spring 66, when the abutting block 65 rotates from the first state to the second state, the abutting block 65 is driven by the padlock plate 6 to move upward by a distance, and at the same time, the abutting block 65 rotates under the action of the torsional spring 66.

[0069] When the abutting block 65 changes from the second state to the first state, the abutting block 65 is driven by the padlock plate 6 to move downward by a distance, and the abutting block 65 abuts with the slide rail 45 and rotates relative to the padlock plate 6.

[0070] The lower end of the slider 44 is provided with a giving-up part 441 for abutting and limiting the abutting block 65, and when the abutting block 65 is in the first state, the abutting block 65 abuts with the giving-up part 441 of the slider 44.

[0071] In this embodiment, when the electric operating device 100 with an indication function is closed, the slider 44 can limit the padlock plate 6 from hanging up, and when the padlock plate 6 is padlocked, the retaining block 65 limits the sliding of the slider 44 to avoid closing, which is safer to use.

[0072] like Figures 1 to 6 , Figure 11 、 Figure 14 As shown, the padlock baffle 7 is slidably arranged in the horizontal direction. When the padlock plate 6 is padlocked, the padlock baffle 7 is blocked between the operating hole 112 and the manual operating plate 8. When the circuit breaker is closed, the padlock baffle 7 moves away from the operating hole 112 and the manual operating plate 8 in the horizontal direction.

[0073] In this embodiment, the padlock baffle 7 is provided to restrict manual operation of the user when the padlock plate 6 is in the padlocked state, thereby preventing the risk of electric shock.

[0074] When the padlock plate 6 moves in the vertical direction, the linkage member 9 drives the padlock baffle 7 to slide in the horizontal direction.

[0075] The plastic liner 10 is provided with a rotating shaft 130 pivotally engaged with the linkage member 9, and the linkage member 9 is rotatably arranged relative to the rotating shaft 130.

[0076] The padlock baffle 7 is vertically penetrated with a stop hole 71 . When the circuit breaker is closed, the padlock plate 6 is in a receiving state, and one end of the linkage member 9 is vertically inserted into the stop hole 71 .

[0077] The padlock baffle 7 is provided with a driving plate 72 protruding downward in the vertical direction. When the padlock plate 6 is switched from the receiving state to the padlock state, the linkage member 9 pushes the driving plate 72 in the horizontal direction to drive the padlock baffle 7 to move in the horizontal direction.

[0078] The padlock baffle 7 is provided with a limiting shaft 73 protruding upward in the vertical direction, and the track groove 114 extends in the horizontal direction. The limiting shaft 73 is inserted into the track groove 114 and is slidable relative to the track groove 114 .

[0079] The driving block 67 is arranged on the padlock plate 6 and used to abut against the linkage 9 in the vertical direction. When the padlock plate 6 moves upward, the driving block 67 can drive the linkage 9 to rotate, on the one hand, so that the end of the linkage 9 is separated from the stop hole 71, and on the other hand, so that the linkage 9 drives the driving plate 72 to move the padlock baffle 7 in the horizontal direction. When the padlock plate 6 moves downward, the upper end of the linkage 9 is gradually inserted into the stop hole 71 and drives the padlock baffle 7 to move in the horizontal direction.

[0080] The padlock baffle 7 is arranged in the exposure groove 81 and abuts against the manual operation plate 8 in the horizontal direction.

[0081] The manual operation plate 8 protrudes into the exposure groove 81 and is provided with a limiting step 83, and the padlock baffle 7 is arranged on the limiting step 83. The limiting step 83 can support the padlock baffle 7 and limit the left and right shaking of the padlock baffle 7.

[0082] When the padlock plate 6 is in the storage state, the user can freely move the manual operation plate 8 without driving the padlock baffle 7 to move, so that the manual operation plate 8 is shielded between the operation hole 112 and the operation disc 3 or the exposure groove 81 is arranged between the operation hole 112 and the operation disc 3. When the padlock plate 6 is in the padlocking state, the padlock baffle 7 drives the manual operation plate 8 to move, although the exposure groove 81 is arranged between the operation hole 112 and the operation disc 3, the padlock baffle 7 is necessarily arranged in the exposure groove 81, so as to shield the operation disc 3 and avoid the danger caused by manual operation.

[0083] The linkage 9 is arranged to drive the padlock plate 6 to drive the padlock baffle 7 to move, so as to avoid the danger caused by manual operation when the padlock is locked.

[0084] The control circuit board 5 is electrically connected with the connecting assembly 4 to control the working of the connecting assembly 4. More specifically, the control circuit board 5 is provided with a switching power supply, a power conversion circuit, a sampling switch and circuit, and a control circuit.

[0088] The drive assembly 102 is used to drive the split and combination indication sliding plate 101 to slide. The drive assembly 102 drives the split and combination indication sliding plate 101 to move, so that the second display part 1011 or the through hole 1012 is located below the display hole 111. When the through hole 1012 is located below the display hole 111, the first display part 32 is exposed from the display hole 111.

[0089] In the embodiment, the first display part 32 is a different color block arranged on the side of the operation disc 3 facing the display cover 11, and the different color blocks are arranged in a circumferential direction. The second display part 1011 is another color block arranged on the split and combination indication sliding plate 101.

[0090] More specifically, the second display part 1011 is a red color block, and the two first display parts 32 are a green color block and a white color block respectively. The identification icon 115 corresponds to different colors. Red represents closing (ON), green represents opening (OFF), and white represents tripping (TRIPPED or TRIP). When the closing is performed, the second display part 1011 is located below the display hole 111, and the display hole 111 can only expose the red color on the second display part 1011. When the opening is performed, the display hole 111 exposes the green color on the first display part 32 through the through hole 1012. In this state, if there is a tripping problem, the operation disc 3 will relatively rotate, and the display hole 111 will expose the white color.

[0091] The drive assembly 102 includes an indication push rod 1021 and an indication rotating part 1022. The indication push rod 1021 and the indication rotating part 1022 are arranged on the side of the split and combination indication sliding plate 101 away from the display cover 11. The indication push rod 1021 slides in a direction perpendicular to the split and combination indication sliding plate 101. The indication rotating part 1022 is driven by the indication push rod 1021 to drive the split and combination indication sliding plate 101 to move in a horizontal direction, so that the second display part 1011 or the through hole 1012 is located below the display hole 111.

[0092] The indication rotating part 1022 and the plastic gasket 10 are rotatably arranged.

[0093] The split-combination indication sliding plate 101 is provided with a driving fastener 1015 protruding towards the indication rotary part 1022, one end of the indication rotary part 1022 is inserted into the driving fastener 1015, so as to drive the split-combination indication sliding plate 101 to slide when the indication rotary part 1022 rotates.

[0099] When closing, the slider 44 is abutted by the abutted block 65, the slider 44 is limited from hanging up by the abutted block 65, at the same time, the limiting protrusion 1024 of the indicating rotary part 1022 is also inserted into the limiting hole 68, further limiting the hanging up of the lock plate 6, playing a double insurance; at the same time, the second display part 1011 is below the display hole 111, showing that it is in the closing state at this time; no matter whether the electric operating device 100 with indicating function is in the opening state or the closing state, as long as the lock plate 6 is not hung up, the user can manually move the manual operating plate 8 to determine whether to control the operating disc 3 in a manual mode;

[0100] When opening and the lock plate 6 is not hung up, the slider 44 is relatively slid, at this time, in the vertical direction, the slider 44 gives the abutted block 65 a clearance, the indicating push rod 1021 is moved upward, driving the indicating rotary part 1022 to rotate, further driving the opening-closing indicating sliding plate 101 to slide, so that the through hole 1012 is located below the display hole 111, exposing the first display part 32, at the same time, the limiting protrusion 1024 is separated from the limiting hole 68, no longer limiting the lock plate 6, in this state, the lock plate 6 can be hung up;

[0101] When opening and the lock plate 6 is hung up, the abutted block 65 is lifted and relatively rotated to abut the slider 44 in the horizontal direction, avoiding closing, at the same time, the driving block 67 is moved upward, driving the linkage 9 to rotate and driving the lock baffle 7 to move to the upper side of the operating disc 3 to shield the key hole 31, avoiding manual operation by the user.

[0102] When the lock is released, the lock plate 6 returns to the storage state under the action of the second reset spring 1023, and the abutted block 65 returns to the first state under the action of the torsional spring 66, releasing the limitation on the slider 44, the lock baffle 7 moves away from between the operating hole 112 and the manual operating plate 8 in the horizontal direction;

[0103] When switching from opening to closing, the slider 44 moves to the upper side of the abutted block 65, the first reset spring 1013 pushes the opening-closing indicating sliding plate 101 to slide, driving the indicating rotary part 1022 to rotate and making the limiting protrusion 1024 inserted into the limiting hole 68.

[0104] The electric operating device 100 with the indication function is compact in structure, convenient to use and high in safety.

[0105] The technical features of the above-described embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure.

[0106] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
