[0019] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.
[0020] like Figure 1 As shown, the utility model is an electric operating mechanism maintenance interlocking structure, comprising a cover 1, in which a slider 6, a clamping block assembly, an electric operating mechanism operating shaft 3, and a button 5 are arranged.
[0021] The surface cover 1 is provided with a slider operation slot 1-1, a shaft operation hole 1-2, a block slot 1-3, and a button hole.
[0022] like Figure 2 As shown, a shaft avoidance hole 6-1 vertically passes through the slider 6; a slider dial 6-2 is provided on the upper part of the slider 6, and the slider dial 6-2 slides in the slider operating groove 1-1. A slider upper arm 6-3 and a slider lower arm 6-4 are respectively provided at the upper and lower ends of the middle part of the slider 6.
[0023] like Figure 3 As shown, the block assembly includes a block 4-1, which slides vertically in the cover 1. A spring 8 is provided between the bottom of the block 4-1 and the cover 1. The spring 8 gives the block 4-1 an upward thrust. A limiting mechanism is provided between the block 4-1 and the cover 1. A lock hole 4-4 is provided on the upper part of the block 4-1 for installing a padlock. The limiting mechanism includes a limiting waist groove 4-2 and a limiting screw 4-3. The limiting waist groove 4-2 is vertically provided in the middle of the block 4-1. The limiting screw 4-3 passes through the limiting waist groove 4-2 and then connects to the cover 1.
[0024] The button 5 is vertically slidably installed in the cover 1 , and a circuit breaker test button 7 is provided below the button 5 .
[0025] An electric operating mechanism for operating the rotating shaft 3 is provided below the rotating shaft operating hole 1-2.
[0026] The slider table 6-2 is installed in the slider operation slot 1-1 by interference fit, so as to prevent the slider table 6-2 from sliding easily in the slider operation slot 1-1.
[0027] In order to ensure that the slider table 6-2 accurately slides to the middle of the slider operation slot 1-1, scale lines are provided on the slider operation slot 1-1.
[0028] The working process of the utility model is as follows:
[0029] The slider protrusion 6-1 of the slider 6 has three positions in the cover window 1-1. 1. The slider protrusion 6-1 is on the left side of the cover window 1-1. At this time, the electric operating mechanism operating shaft 3 is blocked by the slider 6-2, the manual operating handle cannot be inserted into the shaft operating hole 1-2 to operate the shaft 3, and the electric operating mechanism cannot be manually operated.
[0030] 2. The slider protrusion 6-1 is in the middle of the cover window 1-1. At this time, the shaft avoidance hole 6-1 moves below the shaft operation hole 1-2. The manual operating handle can pass through the shaft operation hole 1-2 and the shaft avoidance hole 6-1 and then be inserted into the electric operating mechanism to operate the shaft 3, and manually operate the electric operating mechanism.
[0031] When the slider protrusion 6-1 is at the left side and middle of the cover window 1-1, the slider upper arm 6-3 abuts against the upper end of the block 4-1 to prevent the spring 8 from ejecting the upper part of the block 4-1 out of the block slot 1-3, and the slider lower arm 6-4 is located on the left side of the button 5.
[0032] 3. The slider protrusion 6-1 is on the right side of the cover window 1-1. When the slider protrusion 6-1 is moved from the middle of the cover window 1-1 to the right side, the push button 5 needs to be pressed down from the button hole. The button 5 presses down the circuit breaker test button 7 to ensure that the circuit breaker is in a tripped and disconnected state. At the same time, after the button 5 moves down, the button 5 cannot prevent the slider lower arm 6-4 from moving rightward to above the button 5. When the slider 6 moves rightward, the slider upper arm 6-3 is disengaged from the block 4-1. The block 4-1 pops up from the block slot 1-3 under the action of the spring 8 and is padlocked in the lock hole 4-4. The block 4-1 prevents the slider 6-2 from moving leftward, ensuring that when the block 4-1 pops up, the electric operation button 5 is in a depressed state and the circuit breaker is in a tripped and disconnected state. That is, the slider protrusion 6-1 is on the right side of the cover window 1-1. After the padlock is installed, it can be ensured that the circuit breaker is in the disconnected position, the circuit is powered off, and the personal safety of the line maintenance personnel is ensured.
[0033] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
