[0030] Embodiment:
[0031] The embodiment of the present application discloses an adjustable winding belt tensioning wheel. Please refer to Figure 1 , Figure 2 , Figure 3, including a base 1, on which there are two adjusting components 2. A toothed disc 3 is movably sleeved on the outer wall of each of the two adjusting components 2. The adjusting component 2 includes an adjusting chute 4. A rotating screw 5 is rotatably installed in the adjusting chute 4. A translation block 7 is movably sleeved on the outer wall of the rotating screw 5. A tray 8 is provided at the top of the translation block 7. A fixed shaft 11 is provided at the center of the top of the tray 8. The toothed disc 3 is movably sleeved on the outer wall of the fixed shaft 11. A fixing cap 12 is provided at the top of the fixed shaft 11. There are two threaded through holes on the fixing cap 12, and adjusting screws 13 are provided in the threaded through holes. An activity ring 14 is movably sleeved on the outer wall of the fixed shaft 11. The width dimension of the translation block 7 is the same as the width dimension of the adjusting chute 4. By controlling the rotation of the rotating screw 5, the translation block 7 can be driven to translate in the adjusting chute 4, so as to adjust the distance between the two toothed discs 3 located on the fixed shaft 11.
[0032] Please refer to Figure 2 、 Figure 3 , one side of the rotating screw 5 passes through the inner wall of the adjusting chute 4 and extends to the outside of the base 1. A handle 6 is installed on the side of the rotating screw 5 extending to the outside of the base 1. The side of the rotating screw 5 away from the handle 6 is connected to the inner wall of the adjusting chute 4 through a rotating connection ring, which is convenient for driving the two rotating screws 5 to rotate by holding the handle 6.
[0033] Please refer to Figure 2 、 Figure 3 , a plurality of convex blocks 9 are provided at the top of the tray 8. Hemispherical grooves are provided at the tops of the convex blocks 9, and balls 10 are provided in the hemispherical grooves. The stability of the rotation of the toothed disc 3 can be enhanced through the balls 10.
[0034] Please refer to Figure 2 、 Figure 3 , two rotating connection rings are installed at the top of the activity ring 14, and the tops of the two rotating connection rings are respectively connected to an adjusting screw 13, which is convenient for adjusting the height of the activity ring 14 on the outer wall of the fixed shaft 11 by controlling the rotation of the adjusting screw 13, that is, adjusting the friction between the activity ring 14 and the toothed disc 3.
[0035] Please refer to Figure 2 、 Figure 3 , a plurality of friction plates 15 are provided on the outer wall of the activity ring 14, and the friction plates 15 are fixedly connected to the outer wall of the activity ring 14. By contacting between the friction plates 15 and the toothed disc 3, it can be avoided that only relying on the contact between the activity ring 14 and the toothed disc 3, the limiting effect of the toothed ring 3 on the rotation speed of the activity ring 14 is reduced during long-term use, and it is convenient to increase the friction effect on the toothed disc 3.
[0036] Please refer to Figure 2 、 Figure 3, a square clamping block is provided at the bottom end of the fixed shaft 11, and a square clamping groove matching the square clamping block is provided at the top end of the tray 8, which facilitates the removal of the fixed shaft 11 for maintenance in the later stage, and the square clamping block can prevent the fixed shaft 11 from rotating with the toothed disc 3, resulting in the influence of the fixed shaft 11 on the rotation speed of the toothed disc 3.
[0037] Please refer to Figure 2 、 Figure 3 , a clamping groove is provided at the top end of the fixed shaft 11, and a clamping block is provided in the clamping groove. The top end of the clamping block is fixedly connected to the fixing cap 12, which facilitates the removal of the fixing cap 12 and the removal of the toothed disc 3 for maintenance.
[0038] The implementation principle of this embodiment is as follows: during use, the two rotating screws 5 are rotated according to the thickness of the winding tape, driving the two translation blocks 7 to slide in the adjustment chute 4. At this time, the toothed disc 3 moves with the translation block 7 to adjust the position, that is, the distance between the two toothed discs 3 is adjusted. And during the use process, the friction force between the movable ring 14, the friction plate 15 and the toothed disc 3 can be adjusted by controlling the rotation of the adjustment screw 13 to control the rotation speed of the toothed disc 3.
[0039] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
