The rapid fastening device for the terminal reel is applicable to the rapid fastening treatment of all materials packaged in reels during their feeding and discharging, can achieve rapid material change of the terminals, greatly reduce the fastening time of the terminal reel, improve the loading and unloading efficiency of the terminals, and thus improve the production efficiency.

[0024] Combined Figures 1 to 4 As shown, the rapid fastening device for the terminal reel in this embodiment includes a reel body 10 and a fastening part 20. A fixed shaft 11 is provided at the central position of the reel body 10. The fastening part 20 is located between the reel body 10 and the fixed shaft 11, thereby installing the reel body 10.

[0025] In this embodiment, the fastening part 20 is arranged on the fixed shaft 11. The fastening part 20 includes a driving shaft sleeve 21, a driven shaft sleeve 22, and a fixed shaft sleeve 23. The driving shaft sleeve 21, the driven shaft sleeve 22, and the fixed shaft sleeve 23 are all coaxially arranged with the fixed shaft 11. The driving shaft sleeve 21 pushes the driven shaft sleeve 22 through a spring 30. A ball 40 is arranged on the driven shaft sleeve 22. The fixed shaft sleeve 23 is fixedly connected to the fixed shaft 11. A fastening surface 231 is provided on the fixed shaft sleeve 23. When the driven shaft sleeve 22 drives the ball 40 to fit against the fastening surface 231, the reel body 10 is fastened. When it is necessary to fasten the reel body 10, the operator pushes the driving shaft sleeve 21, and the driving shaft sleeve 21 pushes the driven shaft sleeve 22 through the spring 30. The driven shaft sleeve 22 drives the ball 40 to fit against the fastening surface 231 of the fixed shaft sleeve 23, causing the fastening part 20 to be tightened. And the fastening part 20 is filled between the reel body 10 and the fixed shaft 11, so the fastening of the reel body 10 is realized. When it is necessary to change the material of the reel body 10, the operator pulls the driving shaft sleeve 21 to reset the driven shaft sleeve 22, and then replaces the reel body 10 and fastens it again.

[0026] As Figure 1As shown in the figure, the driving shaft sleeve 21 of this embodiment is located outside the driven shaft sleeve 22 and the fixed shaft sleeve 23. An annular cavity 50 is provided between the driving shaft sleeve 21 and the driven shaft sleeve 22. The spring 30 is located in the annular cavity 50, and one end of the spring 30 is installed on the driving shaft sleeve 21, and the other end is installed on the driven shaft sleeve 22. Therefore, when the driving shaft sleeve 21 is pulled, the driven shaft sleeve 22 can be pulled through the spring 30, so as to realize the fastening and loosening of the reel body 10, so as to quickly replace the reel body 10 and improve the efficiency.

[0027] In this embodiment, a pushing handle 60 is provided at one end of the driving shaft sleeve 21 to push the driving shaft sleeve 21. The pushing handle 60 of this embodiment is fixedly connected to the driving shaft sleeve 21, so that the pushing handle 60 can drive the driving shaft sleeve 21.

[0028] Combined Figure 3 with Figure 4 As shown in the figure, the driven shaft sleeve 22 of this embodiment is provided with concave holes 221. The ball 40 is located in the concave holes 221. The number of concave holes 221 is at least two and is evenly distributed on the surface of the driven shaft sleeve 22. The fastening surface 231 is an arc-shaped inclined surface to cooperate with the ball 40. When fastening the reel body 10, the ball 40 located on the driven shaft sleeve 22 can be guided into the fastening surface 231 of the fixed shaft sleeve 23. When the reel body 10 needs to be replaced, the ball 40 can be separated from the fastening surface 231 for replacement, and then re-fastened after replacement.

[0029] In the actual use of the quick fastening device for the terminal reel of this embodiment, after the reel body 10 is placed, the operator pushes the driving shaft sleeve 21 through the pushing handle 60. The driving shaft sleeve 21 pushes the driven shaft sleeve 22 through the spring 30. The driven shaft sleeve 22 drives the ball 40 to fit the fastening surface 231 of the fixed shaft sleeve 23, so that the fastening part 20 is tightened. The fastening part 20 is filled between the reel body 10 and the fixed shaft 11. Therefore, the fastening of the reel body 10 is realized. When the reel body 10 needs to be refilled, the operator pulls the driving shaft sleeve 21 to reset the driven shaft sleeve 22, and then replaces the reel body 10 and re-fastens it.

[0030] All in all, the quick fastening device for the terminal reel of this embodiment is applicable to the quick fastening treatment of all materials packaged in reels during their feeding and discharging, can realize the quick replacement of terminals, greatly reduce the fastening time of the terminal reel, so as to improve the feeding and discharging efficiency of the terminals, and thus improve the production efficiency.
