[0041] As Figures 1 to 16 shown, the electric operating device 100 with padlock operation prevention function of the utility model includes an outer shell 1, an operating disc 3, a connecting assembly 4, a control circuit board 5, a padlock plate 6, a padlock baffle 7, a manual operating plate 8, a linkage 9, a plastic gasket 10, an on-off indication sliding plate 101 and a driving assembly 102.

[0042] The electric operating device 100 with the lockout function is used to drive the switch handle 2 of the circuit breaker to open or close. The switch handle 2 is shown in the figure to facilitate understanding of the cooperation between the electric operating device 100 with the lockout function and the circuit breaker, and does not mean that the switch handle 2 belongs to the electric operating device 100 with the lockout function.

[0043] As shown in Figures 1 to 4 The shell 1 includes a display cover 11 arranged on one side, a first cover body 12 extending from the display cover 11 towards one side, and a second cover body 13 extending from the first cover body 12 towards a side away from the display cover 11. The second cover body 13 protrudes out of the first cover body 12 in the horizontal direction to form a mounting step 14.

[0044] The plastic gasket 10 is arranged in the shell 1.

[0045] In this embodiment, the direction perpendicular to the display cover 11 is defined as the vertical direction, the direction of the extension of the display cover 11 or parallel to the direction of the extension of the display cover 11 is defined as the horizontal direction, and the direction of the electric operating device 100 with the lockout function towards the display cover 11 is defined as upward, and the direction away from the display cover 11 is defined as downward. Such definition does not mean the position relative to the ground in actual installation or use, and is not limited thereto.

[0046] The display cover 11 is provided with a display hole 111, an operation hole 112 and a moving groove 113; the lower side of the display cover 11 is recessed upward to form a track groove 114. In this embodiment, the track groove 114 does not penetrate through the display cover 11, but is not limited thereto.

[0047] If the open hole type installation is adopted, the first cover body 12 can protrude out of the protective panel to expose the display cover 11 outside the installation cabinet, and the second cover body 13 is hidden in the cabinet. The mounting step 14 plays a limiting role, so that the protection level can be improved.

[0048] The side of the display cover 11 outward can be further provided with an identification icon 115 to indicate that the color, shape and the like displayed from the display hole 111 correspond to the state of the electric operating device 100 with the lockout function. Generally, the electric operating device 100 with the lockout function has at least three states of closing (ON), opening (OFF) and tripping (TRIPPED). The states of closing and opening correspond to the states of closing and opening of the circuit breaker and the electric operating device 100 with the lockout function, and when the circuit breaker is opened, the electric operating device 100 with the lockout function can be in the tripping state. Those skilled in the art can understand that this will not be described here.

[0049] As shown in Figures 5 to 7 , the operation disc 3 is arranged in the outer housing 1 to manually drive the connection assembly 4 to work. In the embodiment, the operation disc 3 is provided with a key hole 31 to allow a user to insert a key to operate the disconnecting and closing.

[0050] The operation hole 112 is arranged right above the operation disc 3 to expose the key hole 31.

[0051] As shown in Figure 1 , 3 , 12, the manual operation plate 8 is provided with an exposure slot 81 penetratingly arranged on the manual operation plate 8, and the manual operation plate 8 is provided with a hand holding protrusion 82 protruding upwardly, which is inserted into the moving slot 113 in the vertical direction and can be manually operated by a user to drive the manual operation plate 8 to move in the horizontal direction.

[0052] The manual operation plate 8 is arranged between the display cover 11 and the operation disc 3, and the manual operation plate 8 has a first position to shield the operation hole 112 and the manual operation plate 8, and a second position to move in the horizontal direction relative to the first position. When the manual operation plate 8 is in the second position, the exposure slot 81 is located between the operation hole 112 and the manual operation plate 8. Without the padlock baffle 7 shielding the exposure slot 81, a user can operate the operation disc 3 through the exposure slot 81.

[0053] 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. When the padlock plate 6 is in the storage state, the padlock hole 61 is located in the outer housing 1. When the padlock plate 6 is in the padlock state, the padlock plate 6 protrudes out of the outer housing 1, and the padlock hole 61 is exposed outside the outer housing 1.

[0054] The plastic lining 10 is provided with a reset plate 110, and the padlock plate 6 is provided with a reset tension spring 62. The reset tension spring 62 connects the padlock plate 6 and the reset plate 110. When the padlock plate 6 protrudes out of the outer housing 1, the reset tension spring 62 is in the stretched state. When the external force is lost, the reset tension spring 62 can automatically drive the padlock plate 6 to change to the storage state.

[0055] The padlock plate 6 is provided with a hook 63, and one end of the reset tension spring 62 is clamped with the hook 63.

[0056] The padlock plate 6 is provided with a guide groove 64 extending in a 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.

[0057] One end of the guide groove 64 is provided with a mounting hole 641 through which the guide part 120 passes. When the guide part 120 is installed, the guide part 120 passes through the mounting hole 641.

[0058] In this embodiment, when the circuit breaker is closed, the padlock plate 6 is necessarily in a concealed state. When the circuit breaker is open, the padlock plate 6 may be in a concealed state or a locked state. Whether to lock or not needs to be selected by the user according to the actual situation. In order to achieve this effect, the following settings are made in this embodiment:

[0059] The padlock plate 6 has a retaining block 65 at the other end away from the padlock hole 61, wherein the padlock hole 61 is close to the display cover 11, and the retaining block 65 is away from the display cover 11.

[0060] The abutment block 65 is rotatably mounted relative to the padlock plate 6.

[0061] The connecting assembly 4 includes a drive 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 operate.

[0062] like Figures 5 to 9 As shown, the gear set 42 is connected to the drive motor 41 and the cam 43. The cam 43 is connected to the gear set 42 and the slider 44. The drive motor 41 drives the gear set 42 to rotate, which in turn drives the cam 43 to rotate. The cam 43 then drives the slider 44 to move. When the electric operating device 100 with padlock anti-operation function is engaged with the circuit breaker, the slider 44 is connected to the switch handle 2. The slider 44 slides horizontally to drive the switch handle 2 to rotate. Thus, the rotation of the switch handle 2 can be driven by the operation of the drive motor 41.

[0063] Meanwhile, the connecting component 4 can connect the operating panel 3 and the switch handle 2. The operating panel 3 rotates axially and drives the switch handle 2 to move through the connecting component 4 to realize the opening or closing of the circuit breaker. In this embodiment, the operating panel 3 is connected to the gear set 42 and the cam 43, and the drive motor 41 has a clutch function. When there is no power supply, the operating panel 3 can be rotated to drive the gear set 42 to rotate, the cam 43 to rotate, and the slider 44 to move.

[0064] The sliding block 44 is slidably arranged relative to the sliding rail 45. The sliding rail 45 extends in a horizontal direction. In the embodiment, the number of the sliding rail 45 is two and the sliding rails are arranged at intervals.

[0065] When the padlock plate 6 is in the storage state, the sliding block 44 can limit the padlock plate 6 from being hung up in a vertical direction. When the padlock plate 6 is locked, the padlock plate 6 limits the sliding block 44 from sliding to limit the breaker from closing.

[0066] Specifically, the abutting block 65 has a first state and a second state. In the embodiment, the first state and the second state are different angles relative to the rotation of the padlock plate 6. When the breaker is closed, the padlock hole 61 is located in the outer shell 1, that is, in the storage state, the abutting block 65 is in the first state, and the abutting block 65 abuts with the sliding block 44 in a vertical direction to limit the padlock plate 6 from moving in the vertical direction. When the breaker is opened and the padlock plate 6 protrudes out of the outer shell 1 for locking, that is, in the locked state, the sliding block 44 moves in a 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 sliding block 44 in the horizontal direction to limit the sliding block 44 from moving in the horizontal direction.

[0067] The abutting block 65 is provided with a torsion 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 the abutting block 65 rotates under the action of the torsion spring 66.

[0068] 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 sliding rail 45 and rotates relative to the padlock plate 6.

[0069] The lower end of the sliding block 44 is provided with a giving-up part 441 for abutting and limiting the abutting block 65. When the abutting block 65 is in the first state, the abutting block 65 abuts with the giving-up part 441 of the sliding block 44.

[0070] In the embodiment, when the electric operating device 100 with the padlock anti-operation function is closed, the sliding block 44 can limit the padlock plate 6 from being hung up. When the padlock plate 6 is locked, the abutting block 65 limits the sliding block 44 from sliding to avoid closing, which is safer in use.

[0071] As Figures 1 to 6 , Figure 11 , Figure 14As shown, the padlock baffle 7 is slidably disposed in the horizontal direction. When the padlock plate 6 is locked, the padlock baffle 7 covers 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.

[0072] In this embodiment, by setting a padlock baffle 7, manual operation by the user is restricted when the padlock plate 6 is in the padlock state, so as to prevent the risk of electric shock.

[0073] When the padlock plate 6 moves vertically, the linkage 9 causes the padlock baffle 7 to slide horizontally.

[0074] The plastic pad 10 is provided with a pivot shaft 130 that pivotally engages with the linkage 9. The linkage 9 is rotatably disposed relative to the pivot shaft 130. In this embodiment, by providing the linkage 9, when the padlock plate 6 moves in the vertical direction, it can drive the padlock baffle 7 to move in the horizontal direction.

[0075] The padlock baffle 7 is provided with a stop hole 71 in the vertical direction. When the circuit breaker is closed, the padlock plate 6 is in the receiving state, and one end of the linkage 9 is inserted into the stop hole 71 in the vertical direction.

[0076] The padlock baffle 7 is provided with a drive plate 72 protruding downward in the vertical direction. When the padlock plate 6 switches from the receiving state to the padlock state, the linkage 9 pushes the drive plate 72 in the horizontal direction to drive the padlock baffle 7 to move in the horizontal direction.

[0077] The padlock baffle 7 is provided with a limiting shaft 73 protruding upward in the vertical direction, the track groove 114 extends in the horizontal direction, the limiting shaft 73 is inserted into the track groove 114 and is slidably disposed relative to the track groove 114.

[0078] The padlock plate 6 is provided with a driving block 67 for abutting 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, causing the end of the linkage 9 to disengage from the stop hole 71, and causing the linkage 9 to push 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 gradually inserts into the stop hole 71, and drives the padlock baffle 7 to move in the horizontal direction.

[0079] The padlock baffle 7 is located within the exposure slot 81 and abuts against the manual operation plate 8 in the horizontal direction.

[0080] The manual operation plate 8 is provided with a limiting step 83 protruding into the exposure slot 81, and the padlock baffle 7 is installed on the limiting step 83. The limiting step 83 supports the padlock baffle 7 and limits the left and right shaking of the padlock baffle 7.

[0081] When the padlock plate 6 is in the storage state, the user can freely move the manual operation plate 8 without moving the padlock baffle 7, so that the manual operation plate 8 is shielded between the operation hole 112 and the operation disc 3 or the exposure slot 81 is located between the operation hole 112 and the operation disc 3. When the padlock plate 6 is in the padlocked state, the padlock baffle 7 pushes the manual operation plate 8 to move, although the exposure slot 81 is located between the operation hole 112 and the operation disc 3, the padlock baffle 7 is necessarily located in the exposure slot 81, thereby shielding the operation disc 3 to avoid the danger caused by manual operation.

[0082] The linkage 9 is arranged to enable the padlock plate 6 to move the padlock baffle 7, thereby avoiding the danger caused by manual operation when padlocking.

[0083] 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.

[0084] The switching power supply is used to control the switching of the driving motor 41, and the power conversion circuit is used to adjust the output voltage. The sampling switch can include manual-automatic state sampling, on-off position sampling, reset signal sampling, or tripping signal sampling. The control circuit can realize remote control and other functions.

[0085] As shown in Figures 1 to 7 , Figures 15 to 16 The display hole 111 vertically faces the operation disc 3. The operation disc 3 is provided with at least two first display parts 32 exposed from the display hole 111.

[0086] The on-off indication sliding plate 101 is arranged between the operation disc 3 and the display cover 11, and the on-off indication sliding plate 101 is provided with a second display part 1011 and a through hole 1012.

[0087] The driving assembly 102 is used to drive the on-off indication sliding plate 101 to slide, and the driving assembly 102 drives the on-off 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.

[0088] 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 is arranged staggered in the circumferential direction. The second display part 1011 is a color block arranged on the other side of the on-off indication sliding plate 101.

[0089] 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 for closing (ON), green for opening (OFF), and white for tripping (TRIPPED or TRIP). When the circuit breaker is closed, 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 circuit breaker is opened, 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 rotate relatively, and the display hole 111 will expose the white color.

[0090] 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 on-off indication sliding plate 101 away from the display cover 11. The indication push rod 1021 slides in a direction perpendicular to the on-off indication sliding plate 101. The indication rotating part 1022 is driven by the indication push rod 1021 to drive the on-off indication sliding plate 101 to move in the horizontal direction, so that the second display part 1011 or the through hole 1012 is located below the display hole 111.

[0091] The indication rotating part 1022 and the plastic gasket 10 are rotatably arranged.

[0092] The on-off indication sliding plate 101 protrudes towards the indication rotating part 1022 and is provided with a drive fastener 1015. One end of the indication rotating part 1022 is inserted into the drive fastener 1015, so that the indication rotating part 1022 drives the on-off indication sliding plate 101 to slide when the indication rotating part 1022 rotates.

[0093] The indication rotating part 1022 is provided with a limiting protrusion 1024, and the hanging lock plate 6 is provided with a limiting hole 68. When the circuit breaker is closed, the limiting protrusion 1024 is inserted into the limiting hole 68 to limit the hanging of the hanging lock plate 6. In the embodiment, in addition to the sliding block 44, the indication rotating part 1022 linked with the on-off indication sliding plate 101 can also limit the hanging of the hanging lock plate 6.

[0094] The outer casing 1 is provided with a reset block 116 protruding toward the open / close indicator slide 101. Specifically, the reset block 116 is provided on the display cover 11. The open / close indicator slide 101 is provided with a first reset spring 1013. When the circuit breaker is closed, the first reset spring 1013 is compressed. When the circuit breaker is opened, the first reset spring 1013 is reset to drive the open / close indicator slide 101 to slide in the horizontal direction.

[0095] The split / open indicator slide plate 101 has a recessed receiving groove 1014 on the side facing the display cover 11, and the first reset spring 1013 is disposed in the receiving groove 1014.

[0096] The indicator push rod 1021 is provided with a second return spring 1023 for abutting against the plastic pad 10. When the circuit breaker is closed, the second return spring 1023 is compressed. When the circuit breaker is opened, the second return spring 1023 is reset to drive the indicator push rod 1021 to slide in the horizontal direction.

[0097] like Figures 1 to 6 As shown, the working process of the electric operating device 100 with padlock anti-operation function of this utility model is as follows: When the electric operating device 100 with padlock anti-operation function needs to control the circuit breaker to close, it must ensure that the padlock plate 6 is in the receiving state, and drive the slider 44 to slide by manual or electric means, thereby driving the switch handle 2 to rotate.

[0098] When the circuit is closed, the slider 44 abuts against the abutting block 65. The slider 44 restricts the padlock plate 6 from being hooked up by abutting against the abutting block 65. At the same time, the limiting protrusion 1024 of the indicating rotary member 1022 is also inserted into the limiting hole 68, further restricting the hooking up of the padlock plate 6, thus providing double protection. Meanwhile, the second display part 1011 is located below the display hole 111, indicating that the circuit is closed. Regardless of whether the electric operating device 100 with padlock anti-operation function is in the open or closed state, as long as the padlock plate 6 is not hooked up, the user can manually move the manual operating panel 8 to decide whether to manually control the operating panel 3.

[0099] When the circuit breaker is open and the padlock plate 6 is not engaged, the slider 44 slides relative to the circuit breaker. At this time, in the vertical direction, the slider 44 makes way for the abutment block 65, and the indicator push rod 1021 moves upward, causing the indicator rotary member 1022 to rotate, which in turn causes the open / close indicator slide 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 disengages from the limiting hole 68 and no longer limits the padlock plate 6. In this state, the padlock plate 6 can be engaged.

[0100] When the switch is opened and the padlock plate 6 is hung, the abutting block 65 is lifted and rotated to abut the sliding block 44 in the horizontal direction to prevent closing, and meanwhile, the driving block 67 moves upward to drive the linkage 9 to rotate and drive the padlock baffle 7 to move to the above of the operation disc 3 to shield the key hole 31, thereby preventing manual operation.

[0101] When the padlock is released, the padlock plate 6 returns to the storage state under the action of the second reset spring 1023, and the abutting block 65 returns to the first state under the action of the torsional spring 66 to release the restriction on the sliding block 44, and the padlock baffle 7 moves away from the operation hole 112 and the manual operation plate 8 in the horizontal direction.

[0102] When the switch is switched from opening to closing, the sliding block 44 moves to the above of the abutting block 65, the first reset spring 1013 pushes the opening and closing indication sliding plate 101 to slide, drives the indication rotary part 1022 to rotate, and makes the limiting protrusion 1024 inserted into the limiting hole 68.

[0103] The electric operating device 100 with the padlock anti-operation function has the effects that the opening and closing indication sliding plate 101 and the driving assembly 102 are arranged to realize the indication of opening, closing and tripping, and can cooperate with the padlock plate 6 to limit the padlock plate 6 when closing; the abutting block 65 is arranged to limit the padlock plate 6 from being hung by the sliding block 44 when closing, and when the padlock plate 6 is hung, the sliding block 44 is limited to move to close, thereby improving the safety; the padlock baffle 7 is arranged to limit manual operation when the padlock plate 6 is hung, thereby further improving the safety.
