DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1 to Figure 4 The dual-power drive sprocket shown includes a gear 1, and the gear 1 is provided with two gears to achieve the effect of dual-power drive. A round sleeve 3 is fixedly connected to the side of the two gears 1 close to each other, and a reinforcing rib 9 is fixedly connected between the gear 1 and the round sleeve 3 to improve the connection strength between the gear 1 and the round sleeve 3. A threaded sleeve 8 is threadedly matched between the two round sleeves 3. When the threaded sleeve 8 is rotated, the two round sleeves 3 can move toward or away from each other, thereby adjusting the distance between the two gears 1, meeting different installation environments, and improving the applicability of the dual-power drive sprocket.

[0023] Furthermore, the friction coefficient between the threaded sleeve 8 and the round sleeve 3 is relatively large, and random rotation will not occur.

[0024] In order to avoid the problem of the distance between the two gear teeth 1 changing due to the accidental collision of the threaded sleeve 8 during the installation process, an annular groove 10 is provided on the outer ring of the threaded sleeve 8. Two annular grooves 10 are provided, and the two annular grooves 10 are respectively distributed at the two ends of the threaded sleeve 8. The inner part of the annular groove 10 is rotatably connected with an annular sleeve 11, and a swivel 12 is fixedly connected between the two annular sleeves 11. The swivel 12 is rotatably arranged outside the threaded sleeve 8. When an accidental collision occurs, the swivel 12 will rotate on the threaded sleeve 8 through the annular sleeve 11, while the threaded sleeve 8 is fixed, so as to achieve the purpose of protecting the threaded sleeve 8; at the same time, the swivel 12 cooperates with the threaded sleeve 8 to improve the stability of the overall structure.

[0025] Furthermore, a ball bearing may be arranged between the ring sleeve 11 and the inner wall of the ring groove 10 to improve the smoothness of the rotation of the ring sleeve 11 .

[0026] In order to realize the rotation adjustment of the threaded sleeve 8, a clamping groove 13 is provided on the outer ring of the threaded sleeve 8, and the clamping groove 13 is set in multiple numbers, and the multiple clamping grooves 13 are evenly distributed around the outer ring of the threaded sleeve 8. A first circular groove 14 is provided on the inner ring of the ring sleeve 11, and a second circular groove 15 is provided on the outer ring of the ring sleeve 11. The second circular groove 15 is connected with the first circular groove 14. A limit rod 16 is slidably provided inside the second circular groove 15, and the limit rod 16 passes through the first circular groove 14 and cooperates with the clamping groove 13. When the limit rod 16 is clamped in the inside of the clamping groove 13, the threaded sleeve 8 can be driven to rotate synchronously by rotating the swivel 12, so that the threaded sleeve 8 can be rotationally adjusted.

[0027] The inner diameter of the second circular groove 15 is larger than the inner diameter of the first circular groove 14. The end of the limiting rod 16 away from the threaded sleeve 8 is fixedly connected with a round block 17. The outer part of the limiting rod 16 is sleeved with a second spring 18. One end of the second spring 18 is fixedly connected to the round block 17, and the other end of the second spring 18 is fixedly connected to the inner wall of the second circular groove 15. Specifically, the round block 17 is pressed toward the slot 13 by the round block 17, so that the limiting rod 16 is clamped inside the slot 13, and the second spring 18 is compressed; and after the adjustment is completed, the resetting elastic force of the second spring 18 causes the round block 17 to drive the limiting rod 16 to reset, and the limiting rod 16 is pulled out from the inside of the slot 13 without affecting the independent rotation of the ring sleeve 11.

[0028] By setting structures such as the circular sleeve 3 and the threaded sleeve 8, the distance between the two gear teeth 1 can be adjusted to meet different installation environments and improve the applicability of the dual-power drive sprocket. At the same time, the swivel 12 can rotate independently on the threaded sleeve 8 through the ring sleeve 11 to prevent the threaded sleeve 8 from rotating due to accidental collision or the like, and the swivel 12 cooperates with the threaded sleeve 8 to improve the stability of the overall structure.

[0029] In order to improve the stability of the matching of the two gear teeth 1, a slide groove 4 is provided on the side of the two circular sleeves 3 that are close to each other, a slider 5 is slidably connected inside the slide groove 4, a round rod 6 is fixedly connected between the two sliders 5, a first spring 7 is fixedly connected to the side of the slider 5 that is away from the round rod 6, and the end of the first spring 7 that is away from the round rod 6 is fixedly connected to the inner wall of the slide groove 4. The slide groove 4, the slider 5 and the round rod 6 are arranged so that the two circular sleeves 3 form a whole, thereby improving the stability of the matching of the two gear teeth 1. At the same time, the first spring 7 is arranged to prevent the round rod 6 and the slider 5 from shaking at will, and the elastic coefficient of the first spring 7 is small, which will not cause the reversal of the ring sleeve 11.

[0030] There are multiple slide grooves 4, and the multiple slide grooves 4 are evenly distributed, so that the round rods 6 and other structures are multiple groups, which further improves the stability of the matching of the two gear teeth 1.

[0031] A weight-reducing hole 2 is provided on the gear tooth 1 , and a plurality of weight-reducing holes 2 are provided, and the plurality of weight-reducing holes 2 are evenly distributed around the axis of the gear tooth 1 . By providing the weight-reducing holes 2 , material costs are reduced and the weight of the gear tooth 1 is reduced.
