Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

A driving gear 3 is fixedly arranged on the output end of the driving motor 2, and the driving gear 3 is rotatably connected to the top surface of the base plate 1.

[0031] The surface of the base plate 1 is provided with a sliding groove 6, and the first reduction structure 4 and the second reduction structure 5 are slidably arranged in the sliding groove 6. The first reduction structure 4 is arranged between the driving gear 3 and the second reduction structure 5, and the first adjustment top plate 41 and the first adjustment bottom plate 45 of the first reduction joint are slidably connected in the sliding groove 6, and the first adjustment top plate 41 and the first adjustment bottom plate 45 are fixedly connected. The first adjustment top plate 41 and the driving gear 3 are located on the same surface of the base plate 1, and the first adjustment bottom plate 45 is located on the other surface of the base plate 1. The top surface of the first adjustment top plate 41 is rotatably provided with a rotating shaft 42, and the circumferential surface of the rotating shaft 42 is provided with a limiting groove 47, and the circumferential surface of the rotating shaft 42 is sleeved with a first gear ring 43, and a limiting block 49 is arranged inside the first gear ring 43, and the first gear ring 43 is limitedly connected through the limiting block 49 and the limiting groove 47. The circumferential surface of the rotating shaft 42 is provided with four L-shaped grooves 48, and the surface of the rotating shaft 42 is fixedly provided with a first fixed cover 44 through the L-shaped grooves 48. The bottom of the first fixed cover 44 is provided with an inner groove 410 adapted to the shape of the rotating shaft 42, and the inner wall of the rotating shaft 42 is provided with four fixed blocks 411, and the shape of the fixed blocks 411 is adapted to the shape of the L-shaped grooves 48. The first fixed cover 44 is fixed between the fixed blocks 411 and the L-shaped grooves 48. The first gear ring 43 on the surface of the rotating shaft 42 is meshed and connected with the driving gear 3, and the bottom of the rotating shaft 42 passes through the first adjustment bottom plate 45. The bottom of the rotating shaft 42 is connected with a transmission gear 46, and the transmission gear 46 is rotatably connected to the first adjustment bottom plate 45. The second reduction structure 5 is slidably connected to the sliding groove 6, and the second adjustment top plate 51 of the second reduction structure 5 is slidably connected to the second adjustment bottom plate 53. The second adjustment top plate 51 and the first adjustment top plate 41 are located on the same side of the base plate 1, and the second adjustment bottom plate 53 and the first adjustment bottom plate 45 are located on the same side. The second adjustment bottom plate 53 is provided with the same rotating shaft 42 as above, and the surface of the rotating shaft 42 is fixedly provided with a second gear ring 54 having a structure similar to the first gear ring 43, and the second gear ring 54 can mesh with the transmission gear 46. A second fixed cover 55 having the same structure as the first fixed cover 44 is provided below the second adjustment bottom plate 53, and the second fixed cover 55 fixes the second gear ring 54. The top end of the rotating shaft 42 extends upward to the second adjustment top plate 51 and is connected with an output rotating shaft 52, and the output rotating shaft 52 is rotatably connected to the second adjustment top plate 51.

[0032] The surface of the base plate 1 is provided with two fixing grooves 7, which are located on both sides of the sliding groove 6. The two sides of the second adjustment top plate 51 are fixedly provided with fixing plates 8, which are located above the fixing grooves 7. The top surface of the fixing plate 8 is threadedly connected with fixing bolts 9.

[0033] Among them, the depth of the L-shaped groove 48 is lower than the depth of the limiting groove 47, providing installation space for the first gear ring 43 or the second gear ring 54; during the rotation of the gear, the rotation direction will drive the first fixed cover 44 and the second fixed cover 55 to move toward the depth of the horizontal groove of the L-shaped groove 48, thereby preventing the first fixed cover 44 and the second fixed cover 55 from falling off.

[0034] When using this multi-stage gear reduction motor structure for dough mixer, a specific first gear ring 43 is fixedly set on the rotating shaft 42 of the first fixed top plate through the limit block 49 and the limit groove 47, and then the empty groove at the bottom of the first fixed cover 44 is aligned with the rotating shaft, and the fixed block 411 is slid in the L-shaped groove 48. When the fixed block 411 reaches the bottom, the first fixed cover 44 is rotated to achieve the effect of fixing the first gear ring 43. Then the first reduction structure 4 is moved to make the first gear ring 43 mesh with the driving gear 3. Then the second gear ring 54 is fixed in the same way as above, and the second gear ring 54 is meshed with the transmission gear 46 by moving the second reduction structure 5. Then the second reduction structure 5 is fixed by the fixing bolt 9. Since the first reduction structure 4 is meshed with the second reduction structure 5 and the driving gear 3, it will be fixed in the middle. Then the output end of the motor drives the driving gear 3 to rotate, and the torque of the driving gear 3 is transmitted by the first reduction structure 4 and the second reduction structure 5 to reduce the output shaft 52. During the rotation of the gear, the rotation direction will drive the first fixing cover 44 and the second fixing cover 55 to move to the depth of the horizontal groove of the L-shaped groove 48, thereby preventing the first fixing cover 44 and the second fixing cover 55 from falling off.

[0035] Working principle of the utility model: the utility model is a multi-stage gear reduction motor structure applied to a dough mixer, by setting a detachable first gear ring 43 and a second gear ring 54, the output end of the motor can drive the first gear ring 43 to rotate, and the first gear ring 43 drives the second gear ring 54 to rotate, thereby reducing the speed of the output shaft 52; the detachable first gear ring 43 and the second gear ring 54 can adjust the reduction transmission ratio, so that this reduction motor structure is suitable for more situations; by setting a first reduction structure 4 and a second reduction structure 5, the first reduction structure 4 and the second reduction structure 5 slide on the sliding groove 6, thereby ensuring that gears with different radius sizes can be engaged with each other, and ensuring that transmission can be performed after adjusting the transmission ratio.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
