DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

Since the reduction gear 5 is rotatably connected to the output shaft 6, the reduction gear 5 The speed gear 5 will not drive the output shaft 6 to rotate. The adjustment component 7 is arranged on one side of the box body 1. The adjustment component 7 includes a positioning hole 701, an identification ruler 702, a positioning rod 703, a retaining ring 704, a spring 705, a rotating seat 706, a sliding column 707, an adjustment plate 708 and a guide rod 709. A positioning hole 701 is opened on one side of the box body 1, and identification rulers 702 are arranged at the upper and lower ends of one side of the box body 1. Through the identification on the identification ruler 702, it is convenient to observe the direction to be adjusted. The positioning hole 701 is slidably connected to the positioning rod 703, and the positioning The upper and lower ends of the positioning rod 703 are fixed with a retaining ring 704, and a spring 705 is provided on one side of the retaining ring 704, and a rotating seat 706 is connected to one side of the spring 705. After releasing the hand, the spring 705 will push the retaining ring 704, so that the positioning rod 703 is inserted into the positioning hole 701, and the adjusted position can be quickly locked, which is beneficial to improve the stability after adjustment. The positioning rod 703 is C-shaped, and the positioning rod 703 is slidably connected to the rotating seat 706. First, pull the positioning rod 703 to separate it from the positioning hole 701, and then rotate the positioning rod 703 to lock the adjusted position. 03 can drive the rotating seat 706 to rotate. A sliding column 707 is fixed on one side of the rotating seat 706, and an adjustment plate 708 is slidably connected to the outer side of the sliding column 707. Guide rods 709 are slidably connected to the inside of both ends of the adjustment plate 708. The rotating seat 706 is rotatably connected to the box body 1, and the box body 1 is fixedly connected to the guide rod 709. During the rotation of the rotating seat 706, the sliding column 707 will push the adjustment plate 708 to slide on the guide rod 709, which can quickly shift gears, thereby being able to quickly adjust the speed of the output shaft 6 according to needs.

[0023] like Figure 1 and Figure 3As shown, the interior of the adjustment plate 708 is provided with a shift assembly 8, the shift assembly 8 includes a spline hub 801 and a coupling sleeve 802, the outer side of the output shaft 6 is fixed with a spline hub 801, and the outer side of the spline hub 801 is slidably connected with the coupling sleeve 802, the coupling sleeve 802 is rotatably connected with the adjustment plate 708, and the width of the groove on one side of the adjustment plate 708 is equal to the diameter of the sliding column 707, the sliding column 707 will drive the adjustment plate 708 to move, the shift assembly 8 also includes a slide groove 803 and a slide rod 804, the interior of the spline hub 801 is provided with a rear slide groove 803, and the interior of the slide groove 803 is slidably connected with the slide rod 804, the shift assembly 8 also includes a synchronizer ring 805 and a gear ring 806, one end of the slide rod 804 is fixed with a synchronizer The synchronous ring 805 is slidably connected with a gear ring 806 on one side of the synchronous ring 805. The synchronous ring 805 drives the spline hub 801 to rotate synchronously through the sliding rod 804 and the sliding groove 803. There are four gear rings 806, and the four gear rings 806 are respectively fixedly connected to the driving gear 3 and the three reduction gears 5. When the coupling sleeve 802 slides on the spline hub 801, it will fit with the synchronous ring 805 on one side, thereby driving the synchronous ring 805 to squeeze the gear ring 806 and increasing the friction between the synchronous ring 805 and the gear ring 806. Therefore, the reduction gear 5 will drive the synchronous ring 805 to rotate through the gear ring 806, thereby reducing the jamming phenomenon in the process of the coupling sleeve 802 sliding from the spline hub 801 to the gear ring 806.

[0024] In summary, when using the non-stop reduction gearbox shifting mechanism, first Figure 1 , Figure 2 and Figure 3In the structure shown in the figure, the motor drives the driving gear 3 to rotate through the input shaft 2, so that the transmission gear set 4 drives multiple reduction gears 5 to rotate, and because the reduction gear 5 is rotationally connected with the output shaft 6, it will not drive the output shaft 6 to rotate. Then, when controlling the speed of the output shaft 6, first pull the positioning rod 703 to separate it from the positioning hole 701, and then rotate the positioning rod 703 to drive the rotating seat 706 to rotate, and rotate the rotating seat 706 in the direction to be adjusted through the mark on the marking scale 702. At this time, the sliding column 707 will push the adjustment plate 708 to make it slide on the guide rod 709, and then, the adjustment plate 708 drives the coupling sleeve 802 to slide on the spline hub 801, and it will fit with the synchronizer ring 805 on one side, thereby driving the synchronizer ring 805 to squeeze the gear ring 806, so the reduction gear 5 will pass through the gear ring 806 drives the synchronizer ring 805 to rotate, and the synchronizer ring 805 will drive the spline hub 801 to rotate synchronously through the slide bar 804 and the slide groove 803, thereby reducing the jamming phenomenon in the process of the coupling sleeve 802 sliding from the spline hub 801 to the gear ring 806. After that, after letting go, the spring 705 will push the retaining ring 704, so that the positioning rod 703 is inserted into the positioning hole 701, and the adjusted position can be quickly locked. Finally, when adjusting other speeds, similarly, it is only necessary to pull and rotate the positioning rod 703 so that a single coupling sleeve 802 is engaged with different gear rings 806, so that the corresponding reduction gear 5 can transmit power through the gear ring 806 through the coupling sleeve 802 and the spline hub 801 to the output shaft 6, so that the motor can perform gear shifting operations during normal operation without stopping, which is more convenient and time-saving, and has higher reliability.
