[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0019] like Figure 1 As shown, a mechanical pull-rope emergency stop reset switch comprises an annular working platform 1, a column 3 is arranged on the outside of the annular working platform 1, a sliding component that can send an on-off signal is connected and fixed to the column 3, and pull ropes 5 are hung on the left and right sides of the sliding component to enable it to slide. The pull ropes 5 are arranged on several guide wheels 2 on the outside of the annular working platform 1 for guiding the pull ropes 5.

[0020] like Figure 1 , 2As shown in Figure 3, the sliding assembly includes a frame 4 fixed on the column 3, and the frame 4 is provided with a sensing slider 7 and a sliding bracket 81 that can slide therein, and the corresponding sensing slider 7 and the sliding bracket 81 are respectively provided with connecting rods 11 extending to the outside of the frame 4, and the corresponding connecting rods 11 are provided with hanging rings 6 for fixing the pull rope 5 at the ends, and the corresponding sensing slider 7 and the sliding bracket 81 are provided with card slots 13 on the upper and lower sides, and the frame 4 is provided with limit components that cooperate with the corresponding card slots 13 on the upper and lower sides.

[0021] like Figure 2 As shown, a spring 12 is provided between the corresponding sensing slider 7 and the sliding bracket 81 and the frame 4 .

[0022] like Figure 2 As shown, a proximity switch 8 is provided on the sliding bracket 81 .

[0023] like Figure 2 As shown, the limiting assembly includes a plurality of U-shaped frames 9 fixed on the upper and lower sides of the frame 4, and a pin 14 is slidably connected to the inside of the corresponding U-shaped frame 9, and the pin 14 extends to the pull ring 10 outside the U-shaped frame 9.

[0024] like Figure 2 As shown, a return spring 15 is arranged inside the corresponding U-shaped frame 9 , one end of the return spring 15 is connected and fixed to the pin shaft 14 and the other end is connected and fixed to the inner side of the U-shaped frame 9 .

[0025] like Figure 1 As shown, the pull rope 5 between the guide wheels 2 forms a pulling area.

[0026] The implementation principle of a mechanical pull-cord emergency stop reset switch in the embodiment of the present application is:

[0027] When the equipment of the assembly line is operating normally, the sensing slider 7 and the sliding bracket 81 equipped with the proximity switch 8 will be moved closer to the middle by the rebound force of the spring 12. At the same time, the proximity switch 8 will generate a passage signal with the sensing slider 7 and send the signal to the equipment to ensure its normal operation. At the same time, the corresponding pin shaft 14 will be lifted up by the sensing slider 7 or the sliding bracket 81 outside the card slot 13, so that the reset spring 15 is compressed to generate a rebound force.

[0028] When the equipment in the assembly line needs to stop urgently, the pull rope 5 can be pulled in any pulling area. When the pull rope 5 is pulled, the corresponding sensing slider 7 or the sliding bracket 81 equipped with the proximity switch 8 will be driven to move parallel in the relative direction, and the spring 12 will be squeezed to retract and generate a rebound force.

[0029] During the parallel movement, the card slot 13 will move parallel to the bottom of the pin shaft 14, and the pin shaft 14 will be rebounded by the return spring 15 to pass through the through hole on the frame 4 and enter the card slot 13, so that the distance between the sensing slider 7 and the proximity switch 8 becomes larger, and the proximity switch 8 cannot sense the sensing slider 7, so it generates a circuit breaker signal, and sends the signal to the device to cut off the power of the device, so that it stops working and prepares for maintenance or handling abnormal situations;

[0030] After the inspection is completed or the abnormal situation is handled, the pull ring 10 is pulled out to pull the pin 14 out of the slot 13. After pulling it out, the distance between the sensing slider 7 and the proximity switch 8 becomes smaller, the proximity switch 8 and the sensing slider 7 generate a passage signal again, and the equipment starts to work normally.

[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
