[0025] As Figures 1 to 9 shown, an embodiment of the present application provides an intelligent electric telescopic pin, including a box body 10, a guide rail 11, a driving rack 12 sliding along the guide rail 11, a driving gear 13 meshing with the driving rack 12, a reduction motor 14 driving the driving gear 13 to rotate, a pin shaft 15, a guide rod 16 and a spring 17; the spring 17 is sleeved outside the guide rod 16 and its top extends out of the guide rod 16; a flange guide sleeve 18 is provided at the top of the box body 10, the pin shaft 15 is movably inserted into the flange guide sleeve 18, an installation hole 19 is provided at the bottom of the pin shaft 15, a retraction driving disc 20 is provided on the circumferential wall of the bottom of the pin shaft 15, the bottom of the guide rod 16 contacts the bottom of the box body 10, and the top is inserted into the installation hole 19, the bottom of the spring 17 contacts the bottom of the box body 10, and the top is inserted into the installation hole 19, the driving rack 12 is connected with a rotating wheel 21, and the rotating wheel 21 contacts the retraction driving disc 20 and is used to drive the pin shaft 15 to move downward along the flange guide sleeve 18.

[0026] As Figures 1 to 9As shown in the figure, the reduction motor 14 drives the driving gear 13 to rotate forward and backward. When the reduction motor 14 drives the driving gear 13 to rotate in one direction, the driving gear 13 drives the driving rack 12 to move downward. The driving rack 12 drives the retracted driving disc 20 and the pin shaft 15 to move downward through the rotating wheel 21. The pin shaft 15 moves downward along the flange guide sleeve 18, and the spring 17 is in a compressed state. When the pin shaft 15 is completely retracted into the flange guide sleeve 18, the present utility model moves to the lower part of the object to be hung, so that when the pin shaft 15 is located below the hanging hole of the object to be hung, when the reduction motor 14 drives the driving gear 13 to rotate in the other direction, the driving gear 13 drives the driving rack 12 to move upward. Under the action of the elastic force of the spring 17, the pin shaft 15 and the retracted driving disc 20 move upward, and the pin shaft 15 moves upward along the flange guide sleeve 18. The pin shaft 15 is inserted into the hanging hole of the object to be hung. At this time, the present utility model can tow the hung object to move.

[0027] As Figures 1 to 9 shown, since the upward movement of the pin shaft 15 and the retracted driving disc 20 is driven by the spring 17, even if the pin shaft 15 is not aligned with the hanging hole of the object to be hung, or there is a foreign object in the hanging hole of the object to be hung, the reduction motor 14 will not be stuck.

[0028] As Figures 1 to 9 shown, the intelligent electric telescopic pin further includes a single-chip microcomputer control board 22, an A touch switch 23 and a B touch switch 24. The reduction motor 14, the A touch switch 23 and the B touch switch 24 are respectively connected to the single-chip microcomputer control board 22. The A touch switch 23 and the B touch switch 24 are respectively arranged at both ends of the moving direction of the pin shaft 15. When the driving gear 13 on the reduction motor 14 pushes the driving rack 12 to drive the retracted driving disc 20 to move back and forth, the retracted driving disc 20 contacts the A touch switch or the B touch switch respectively.

[0029] The A touch switch 23 is arranged above the B touch switch 24. When the rotating wheel 21 pushes the retracted driving disc 20 to move up and down, the retracted driving disc 20 contacts the A touch switch 23 or the B touch switch 24 respectively.

[0030] As Figures 1 to 9As shown in the figure, when the reduction motor 14 drives the driving gear 13 to rotate in one direction, the driving gear 13 drives the driving rack 12 to move downward. The driving rack 12 drives the retracting driving disc 20 and the pin shaft 15 to move downward through the rotating wheel 21. The pin shaft 15 moves downward along the flange guide sleeve 18. The retracting driving disc 20 disengages from the A touch switch 23, and the spring 17 is in a compressed state. When the pin shaft 15 is completely retracted into the flange guide sleeve 18, the retracting driving disc 20 contacts the B touch switch 24. When the present utility model moves to below the object to be hung and the pin shaft 15 is located below the hanging hole of the object to be hung, when the reduction motor 14 drives the driving gear 13 to rotate in the other direction, the driving gear 13 drives the driving rack 12 to move upward. Under the action of the elastic force of the spring 17, the pin shaft 15 and the retracting driving disc 20 move upward. The retracting driving disc 20 disengages from the B touch switch 24, and the pin shaft 15 moves upward along the flange guide sleeve 18. The pin shaft 15 is inserted into the hanging hole of the object to be hung. At this time, the present utility model can tow the hung object to move.

[0031] As Figures 1 to 9 shown, the single-chip microcomputer control board 22 is connected with an alarm. When the pin shaft 15 is not aligned with the hanging hole of the object to be hung, or there is a foreign object in the hanging hole of the object to be hung, the reduction motor 14 continuously rotates the driving gear 13 forward and backward. Under the action of the spring 17 and the driving force of the reduction motor 14, the pin shaft 15 continuously moves up and down, so that the pin shaft 15 is aligned with the hanging hole of the object to be hung, or the foreign object in the hanging hole of the object to be hung is pushed out. When the pin shaft 15 moves back and forth to reach the predetermined number of times, the single-chip microcomputer control board 22 controls the alarm to give an alarm. After the alarm, the staff can handle it.

[0032] As Figures 1 to 9 shown, a notch portion 25 is provided on the peripheral wall of the driving gear 13, and there is a gap between the notch portion 25 and the driving rack 12. During installation, the notch portion 25 of the driving gear 13 is parallel to the driving rack 12, and the notch portion 25 does not contact the driving rack 12. After installation, the reduction motor 14 drives the driving gear 13 to mesh with the driving rack 12, which is convenient for the installation of the driving gear 13 and the driving rack 12, and is beneficial to the flexibility of debugging the present utility model without power.

[0033] As Figures 1 to 9 shown, the driving gear 13 extends with an extension portion 26. A slider 27 is connected to the front surface of the extension portion 26. The slider 27 is slidably connected to the guide rail 11. The rotating wheel 21 is rotatably arranged on the back surface of the extension portion 26.

[0034] As Figures 1 to 9As shown, the rotating wheel 21 is located on the upper surface of the retracting drive disk 20 and in contact with it. When the driving gear 13 moves downward, the rotating wheel 21 drives the retracting drive disk 20 and the pin shaft 15 to move downward. The pin shaft 15 moves downward along the flange guide sleeve 18, and the spring 17 is in a compressed state. When the pin shaft 15 is completely retracted into the flange guide sleeve 18, the present utility model moves below the object to be hooked. When the pin shaft 15 is located below the hanging hole of the object to be hooked, when the reduction motor 14 drives the driving gear 13 to rotate in the other direction, the driving gear 13 drives the driving rack 12 to move upward. Under the action of the elastic force of the spring 17, the pin shaft 15 and the retracting drive disk 20 move upward. The pin shaft 15 moves upward along the flange guide sleeve 18, and the pin shaft 15 is inserted into the hanging hole of the object to be hooked. At this time, the present utility model can tow the hooked object to move.

[0035] As Figures 1 to 9 shown, the guide rail 11 is fixedly connected to the side wall of the box body 10, and the driving gear 13 and the reduction motor 14 are fixedly connected to the side wall of the box body 10 through the support frame 28.

[0036] As Figures 1 to 9 shown, in the present utility model, the guide rail 11, the driving rack 12, the driving gear 13, the reduction motor 14, the pin shaft 15, the guide rod 16 and the spring 17 are located inside the box body 10, making the whole structure compact and small in volume.

[0037] As Figures 1 to 9 shown, a socket 29 is provided on the side wall of the box body 10, and the socket 29 is connected to the single-chip microcomputer control board 22.
