[0016] The utility model is further described below in conjunction with specific embodiments.

[0017] An operation interlocking device of an electric operating mechanism, comprising a partition plate 1, a fixing plate 2, a fixing plate center hole 2.1, a first slider 3, a first slider center hole 3.1, a first slider protrusion 3.2, a second slider 4, a lock core 5, a lock baffle 6, a release button 7, a button arm 7.1, a housing 8 and a cover 9;

[0018] A partition 1 is fixed in the shell, a fixing plate 2 is fixed above the partition 1, a fixing plate center hole 2.1 is opened on the fixing plate 2, and a manual operation shaft of the electric operating mechanism is arranged in the fixing plate center hole 2.1; the first slider 3 is slidably installed on the upper surface of the fixing plate 2, the first slider 3 can slide left and right relative to the fixing plate 2, a first slider center hole 3.1 is opened on the first slider 3, the first slider center hole 3.1 cooperates with the fixing plate center hole 2.1, when the first slider 3 moves to the leftmost side along the fixing plate 2, the first slider center hole 3.1 and the fixing plate center hole 2.1 are staggered, when the first slider 3 moves to the right along the fixing plate 2 to the middle position, the first slider center hole 3.1 and the fixing plate center hole 2.1 are concentrically arranged, and a first slider protrusion 3.2 is provided on the upper surface of the first slider 3, with the help of the first slider protrusion 3.2, the slider 3 can be moved left and right;

[0019] The second slider 4 is slidably mounted on the fixed plate 2. The second slider 4 can slide left and right relative to the fixed plate 2. A return spring is mounted on the fixed plate 2. The other end of the return spring is connected to the second slider 4.

[0020] The face cover 9 is installed on the shell 8, and the face cover 9 cooperates with the shell 8. A lock core 5 is installed on the face cover 9, and a lock baffle 6 is fixed on the lock core 5, and the lock baffle 6 cooperates with the second slider 4; a trip button 7 is installed in the shell on the left side of the corresponding lock core 5, and a button arm 7.1 is provided on the trip button 7. The distance between the lower surface of the button arm 7.1 and the lower surface of the shell is greater than the distance between the upper surface of the second slider 4 and the lower surface of the shell, and the button arm 7.1 cooperates with the second slider 4. When the second slider 4 moves to the left to the leftmost side along the fixing plate 2, part of the second slider 4 is below the button arm 7.1, so that the trip button 7 cannot be pressed down.

[0021] A rectangular cover window 9.1 is provided on the cover 9, and the length direction of the cover window 9.1 is the left-right direction. A baffle 10 is fixed in the housing 8 below the cover window 9.1, and a rectangular baffle window 10.1 is provided on the baffle 10, and the first slider protrusion 3.2 extends upward from the baffle window 10.1 and the cover window 9.1.

[0022] The second sliding block 4 is located below the first sliding block 3 .

[0023] like Figure 1 and Figure 2 As shown, in the unlocked state, the first slider protrusion 3.2 is located at the leftmost side of the baffle window 10.1, and the electric operating mechanism can realize electric operation (that is, remote automatic closing and opening operations can be realized through remote closing and opening signals).

[0024] like Figure 5 As shown, when the first slider 3 is moved to the right to the middle position by the first slider protrusion 3.2, the center hole 3.1 of the first slider is concentric with the center hole 2.1 of the fixing plate, the manual operating handle 11 can be inserted into the slot of the manual operating shaft of the electric operating mechanism, and the manual operating handle 11 can be rotated clockwise to realize manual operation of the electric operating mechanism.

[0025] like Figure 3 and Figure 4As shown, when locking, the lock cylinder 5 of the running lock is rotated counterclockwise, the lock cylinder 5 is in a locked state, the lock baffle 6 and the lock cylinder 5 are rotated counterclockwise by 90°, and the lock baffle 6 stops the second slider 4, which can prevent the second slider 4 from moving to the right, that is, the protrusion 3.2 of the first slider is positioned at the leftmost side of the baffle window 10.1. At this time, the card slot of the manual operation shaft of the electric operating mechanism is misaligned with the first slider 3, and the electric operating mechanism cannot be operated by the manual operating handle 11, and the electric operating mechanism is always in the electric operation state; in addition, during the locking process, the lock baffle 6 pushes the second slider 4 to slide to the left, and the second slider 4 is partially stopped below the button arm 7.1, preventing the trip button 7 from moving downward, that is, the trip button 7 is in an invalid state, and the circuit breaker can no longer be tripped or disconnected by pressing the trip button 7.

[0026] After locking, if the lock core 5 is rotated clockwise, the lock baffle 6 and the lock core 5 are rotated clockwise by 90°, and the second slider 4 is reset under the elastic force of the reset spring, and the utility model is in the unlocked state again.

[0027] In summary, after the operation lock is locked, it can be ensured that the electric operating mechanism can only be operated automatically, and the electric operating mechanism cannot be operated by manually operating the handle 11 or pressing the trip button 7, thereby avoiding unnecessary misoperation.
