If two motors are used as power sources at the same time, the operation may be more troublesome and the access to the power supply may be more complicated. Therefore, a bidirectional rotating motor shaft is needed. Utility Model Content

[0009] Preferably, the inner walls of the inner rotating shaft and the outer rotating shaft are provided with limiting holes connected to the fixing assembly. The setting of the limiting holes ensures that the inner rotating shaft and the outer rotating shaft can be fixed to the rotating rod a and the rotating rod b through the fixing assembly.

[0010] The utility model provides a motor rotating shaft capable of bidirectional rotation, which has the following beneficial effects:

[0011] (1) The utility model sets a rotating mechanism, drives the rotating rod a to rotate through the rotor, and through the joint action of gear a, gear b, gear c and gear d, the rotating rod b can rotate in the opposite direction to the rotating rod a, thereby ensuring that the inner rotating shaft and the outer rotating shaft can rotate in opposite directions, thereby achieving the effect of bidirectional rotation.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1

[0021] See also Figure 1-3A bidirectionally rotating motor shaft comprises a motor body 1, a rotor 2 is arranged inside the motor body 1, a rotating mechanism 3 is arranged outside the rotor 2, the rotating mechanism 3 comprises a rotating rod a31, the rotating rod a31 is fixedly connected to the rotor 2, the rotating rod a31 is fixedly connected to a gear a32, the motor body 1 is rotatably connected to a gear b33 through an L-shaped rod, the gear b33 is meshed with the gear a32, the motor body 1 is rotatably connected to a gear c34 through an L-shaped rod, the gear c34 is meshed with the gear b33, a rotating rod b35 is rotatably connected to the outer wall of the rotating rod a31, a gear d36 is fixedly connected to the outer wall of the rotating rod b35, the radius of the gear a32 and the diameter of the gear b33 are exactly the same as the radius of the gear d36, and the ratio of the sum of the radius of the gear a32 and the diameter of the gear b33 to the radius of the gear d36 ensures that the gear c34 can reach exactly the same speed at the same time. In the state of meshing with gear b33 and gear d36, the length of gear c34 is consistent with the length from the side of gear a32 away from gear d36 to the side of gear d36 away from gear a32. By setting the length of gear c34, it is ensured that gear c34 can mesh with gear b33 and gear d36 at the same time, thereby ensuring that the expected effect can be achieved. Gear d36 is meshed with gear c34, and rotating rod a31 is movably connected with inner rotating shaft 38 through fixing assembly 37. Rotating rod b35 is movably connected with outer rotating shaft 39 through fixing assembly 37. Rotating rod a31 is driven to rotate by rotor 2, and through the joint action of gear a32, gear b33, gear c34 and gear d36, rotating rod b35 can rotate in the opposite direction to rotating rod a31, thereby ensuring that inner rotating shaft 38 and outer rotating shaft 39 can rotate in opposite directions, thereby achieving the effect of bidirectional rotation.

[0022] When in use, the staff first connects the inner rotating shaft 38 with the rotating rod a31 and the outer rotating shaft 39 with the rotating rod b35 through the fixing assembly 37, and then the staff starts the motor body 1 to make the rotor 2 rotate. At this time, the rotating rod a31 rotates under the drive of the rotor 2, and drives the gear a32 to rotate. Since the gear a32 is meshed with the gear b33, the gear a32 can drive the gear b33 to rotate in the opposite direction when it rotates. Since the gear b33 is meshed with the gear c34, the gear b33 can drive the gear c34 to rotate forward. Since the gear c34 is meshed with the gear d36, the gear c34 can drive the gear d36 to rotate in the opposite direction, so that the rotating rod b35 can generate a force to rotate in the opposite direction to the rotating rod a31 under the drive of the gear d36. Since the inner rotating shaft 38 is relatively fixed to the rotating rod a31, and the outer rotating shaft 39 is relatively fixed to the rotating rod b35, the inner rotating shaft 38 and the outer rotating shaft 39 rotate in opposite directions at this time, thereby achieving a two-way rotation effect.

[0023] Embodiment 2

[0024] See also Figure 1-5On the basis of the first embodiment, the fixing component 37 includes a fixing block 371, the fixing block 371 is fixedly connected to one end of the elastic telescopic rod 372, and the end of the elastic telescopic rod 372 away from the fixing block 371 is fixedly connected to the sliding block 373. The number of the fixing components 37 is set to two, and the two fixing components 37 are respectively arranged on the outer walls of the rotating rod a31 and the rotating rod b35, and one fixing block 371 is fixedly connected to the outer wall of the rotating rod a31, and the other fixing block 371 is fixedly connected to the outer wall of the rotating rod b35, one of the sliding blocks 373 is slidably connected to the outer wall of the rotating rod b35, and the other sliding block 373 is slidably connected to the outer wall of the rotating rod a31. Through the arrangement of the two fixing components 37, it is ensured that the inner rotating shaft 38 is connected to the rotating rod a31, and the outer rotating shaft 39 is connected to the rotating rod b 35 can be fixed by the fixing assembly 37, so as to fix the two rotating shafts at the same time, so as to ensure that the effect of bidirectional rotation can be achieved. The inner walls of the inner rotating shaft 38 and the outer rotating shaft 39 are provided with limiting holes connected to the fixing assembly 37. Through the setting of the limiting holes, it is ensured that the inner rotating shaft 38 and the outer rotating shaft 39 can be fixed to the rotating rod a31 and the rotating rod b35 through the fixing assembly 37. The sliding block 373 is squeezed by the inner walls of the inner rotating shaft 38 and the outer rotating shaft 39, so that the sliding block 373 first moves in the direction close to the fixed block 371. When the upper ends of the sliding block 373 and the fixed block 371 enter the upper area of ​​the limiting holes provided in the inner walls of the inner rotating shaft 38 and the outer rotating shaft 39, they move in the direction away from the fixed block 371 driven by the elastic telescopic rod 372, so as to achieve a fixing effect.

[0025] During use, based on Example 1, when the staff needs to fix the inner rotating shaft 38 and the outer rotating shaft 39, the staff first places the through hole opened on the inner rotating shaft 38 and the fixing component 37 set on the rotating rod a31 at the same horizontal position, and then moves the inner rotating shaft 38 toward the side close to the rotating rod a31. When the sliding block 373 contacts the inner wall of the inner rotating shaft 38, the sliding block 373 moves toward the direction close to the fixing block 371, and after the upper ends of the sliding block 373 and the fixing block 371 enter the larger through hole above the inner rotating shaft 38, they are reset under the action of the elastic telescopic rod 372. Then the staff places the through hole opened on the outer rotating shaft 39 and the fixing component 37 set on the rotating rod b35 at the same horizontal position, and repeats the above operations to achieve the fixing effect.
