Referring to fig. 10, 11, 12 and 15, a synchronous spring 421 is disposed between the side of the rotating member 42 away from the axis of the driven turntable 44 and the driven turntable 44, and the upper and lower portions of the rotating member 42 close to the axis of the driven turntable 44 are both provided with arc surfaces; when the button head is pressed, the edge of the button head contacts with one side of the rotating member 42 close to the axis of the driven turntable 44 and is matched with the inclined surface of the rotating member, so that the rotating member 42 is pushed towards the sliding groove 434, and the synchronous spring 421 is compressed; the button head can be inserted into the driven turntable 44, so that the phenomenon of pressing failure caused by the fact that the button head is not pressed is avoided; when the rotating member 42 rotates to the anti-slip groove position, the synchronous spring 421 pushes the rotating member 42 to extend into the anti-slip groove, so as to drive the button head to rotate and reset; the rotating piece 42 is used for driving the button head to rotate and reset in a mode of being clamped in the anti-skidding groove, so that the button head can be smoothly popped out from the driven turntable 44 after being rotated to a reset angle, and the button head is prevented from being damaged by excessive rotation.
Referring to fig. 2, 9, 14 and 15, the inside of the side wall of the device frame 1 is provided with a reset piece 12 for resetting the rotating rod 431 at equal intervals left and right along the length direction thereof, and the inside of the side wall of the device frame 1 is provided with a locking piece 13 for locking the initial position of the rotating rod 431 at equal intervals up and down along the length direction thereof; after the shift lever 451 moves over the rotation rod 431, the reset member 12 in the corresponding position pushes the rotation rod 431 to the left to the position of the locking member 13 by its own elastic force, so that the rotation rod 431 returns to the initial position, thereby returning the driving turntable 43 to the initial position; the reset member 12 is used to restore the active dial 43 to the initial position after the button head has been rotationally reset, in order to handle the next reset action.
When the life detection is carried out on the emergency stop button, the invention comprises the following steps: firstly, manually rotating a height screw 23, wherein the height screw 23 drives an alignment frame 2 to move up and down to a position where a button head can be pressed to be locked by a pressing rod 52; the rotating rod 431 is rotated to be positioned at the left side of the device frame 1, then the sliding bracket 41 is lifted, then the emergency stop button is manually moved to the inside of the alignment frame 2, and the two alignment plates 21 push the base to be positioned at the central position of the alignment frame 2 left and right under the action of the elastic force of the alignment spring 22.
Secondly, pushing the emergency stop button to the inside of the alignment frame 2, moving the fastening stud to the inside of the notch formed by the upper clamping plate 32 and the lower clamping plate 33, then adjusting the height of the clamping frame 31 until the upper clamping plate 32 is tightly attached to the lower part of the button head, and then rotating the locking screw to lock the position of the clamping frame 31; then, a piston rod of the clamping cylinder 36 extends forwards to push the top block 35 forwards, and the lower clamping plate 33 is pushed downwards through an inclined plane arranged at the front part of the piston rod, so that the lower clamping plate 33 is tightly abutted against the upper end face of the fastener, and the emergency stop button is installed and fixed; then, the sliding bracket 41 is moved down to the initial position; the lock member 13 is lifted, the rotating lever 431 is rotated to the right side of the lock member 13, and then the lock member 13 is restored to the original position.
Thirdly, starting the actuating motor 6, driving the cam shaft 51 to rotate by the actuating motor 6 through a belt, and pushing the pressing rod 52 downwards by the cam shaft 51 to be in contact with the button head, and pressing the pressing rod downwards into the driven turntable 44 to be self-locked; the pressing lever 52 is restored to the initial position by the elastic force of the return spring 53; at this time, the following two cases A and B occur: A. when the anti-skid groove corresponds to the rotating part 42, the rotating part 42 extends into the anti-skid groove; when the device is reset, the actuating motor 6 drives the shift lever 451 to rotate to the rotating rod 431 through the transmission belt 45, the rotating rod 431 is pushed to rotate, and the rotating rod 431 drives the driving turntable 43 to rotate; B. when the anti-slip groove is staggered with the position of the rotating piece 42, the button head pushes the rotating piece 42 to be inserted into the sliding groove 434, and simultaneously compresses the synchronous spring 421; when the reset is performed, the execution motor 6 drives the shift lever 451 to rotate to the rotating rod 431 through the transmission belt 45, and pushes the rotating rod 431 to rotate; at this time, the driving rotary plate 43 drives the rotating member 42 to rotate synchronously with the driven rotary plate 44 through the rotating member 42 inserted into the sliding slot 434, and when the rotating member 42 rotates to the anti-slip slot position at the button head, the synchronous spring 421 pushes the rotating member 42 to extend into the anti-slip slot and withdraw from the sliding slot 434.
Fourthly, the driving turntable 43 independently rotates without driving the driven turntable 44 to rotate, so that the positions of the sliding groove 434 and the rotating member 42 are shifted, and the rotating member 42 cannot move into the sliding groove 434; subsequently, when the pushing block 433 rotates through the notch of the guide rail 441 to contact with the guide rail 441, the driving rotary disc 43 drives the driven rotary disc 44 to rotate through the pushing block 433, and the driven rotary disc 44 drives the button head to rotate and reset through the rotating member 42.
Fifthly, when the button head rotates to the reset angle, the button head is automatically unlocked and popped out, so that the button head is separated from the rotating part 42, and the rotating part 42 can not drive the button head to rotate; after the shift lever 451 moves to pass over the rotation lever 431, the reset member 12 pushes the rotation lever 431 to the position of the lock member 13 by its own elastic force, so that the rotation lever 431 returns to the initial position, thereby returning the driving dial 43 to the initial position; the driving turntable 43 is held in the relative position in the initial state by the elastic force of the position spring 46, so that the rotation member 42 can be inserted into the inside of the driving turntable 43 again.
And sixthly, repeating the third step to the fifth step, and continuously detecting the service life of the emergency stop button.
