[0004] However, in the prior art, high-torque roller reduction motors are mainly used to provide greater output power. Greater output power is usually suitable for large roller conveyor belts. The overall size of large roller conveyor belts is larger than that of ordinary roller conveyor belts. When the output end of the reduction motor is connected to the roller, due to the larger size, some output shafts cannot be normally connected to the roller, which in turn has a certain impact on the overall connection stability and structural strength. Long-term use is prone to structural loosening. Summary of the invention

[0005] The utility model aims to solve the problem in the prior art that some output shafts cannot be normally docked with the roller table, and proposes a large torque roller table reduction motor.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a large torque roller reducer motor, including a reducer motor body 1, an output shaft 3 is installed inside the reducer motor body 1, an expansion assembly 2 is fixedly installed on the outer wall of the output shaft 3, the expansion assembly 2 includes a movable ring 21, a fixed ring 22, a docking block 25, a first support rod 26 and a second support rod 27, a convex block 23 is fixedly installed on the edge of the movable ring 21 and the edge of the fixed ring 22, one end of the first support rod 26 is rotatably connected to the convex block 23 of the movable ring 21, and the second support rod 27 One end of the docking block 25 is rotatably connected to the protrusion 23 of the fixed ring 22, one end of the docking block 25 is slidably connected to a movable block 28, the movable block 28 is rotatably connected to the other end of the second support rod 27, the other end of the first support rod 26 is rotatably connected to the other end of the docking block 25, the first support rod 26 is rotatably connected to the second support rod 27, a threaded rod 24 is rotatably installed inside the fixed ring 22, the threaded rod 24 is threadedly connected to the movable ring 21, and a T-shaped groove 212 is provided at the intersection of the docking block 25 and the movable block 28.

[0026] The specific configuration and function of this embodiment are described in detail below. The output shaft 3 is installed inside the reduction motor body 1, and the expansion assembly 2 is installed on the output shaft 3. When the output shaft 3 is connected to the roller, the output shaft 3 is first inserted into the inside of the roller, and the output shaft 3 is used to directly replace the central axis of the roller, and the docking block 25 on the expansion assembly 2 is in contact with the inner wall of the roller. At this time, the expansion assembly 2 is completely inside the roller, and then the threaded rod 24 is rotated at the opening at the other end of the roller. When the threaded rod 24 rotates, it will drive the movable ring 21 to move along the direction of the output shaft 3;

[0027] When the movable ring 21 moves, it will push the first support rod 26 to rotate. At this time, the movable block 28 will move along the direction of the T-shaped slide groove 212, so that the second support rod 27 will also rotate synchronously. The rotation of the first support rod 26 and the second support rod 27 will expand the distance between the docking block 25 and the output shaft 3, thereby achieving the purpose of expanding the overall size, so that the output shaft 3 can be normally connected to the large roller. The existence of the protrusion 23 provides a movable space for the rotation of the first support rod 26 and the second support rod 27, avoiding the fixed ring 22 and the movable ring 21 affecting the normal rotation of the rod body. Embodiment 2

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, a connector 29 is fixedly installed at the other end of the threaded rod 24, and the connector 29 is located on one side of the movable ring 21. Both sides of the connector 29 are rotatably connected with a rotating rod 210, and the rotating rod 210 is set as a bending structure. A positioning plate 211 is fixedly installed on one side of the rotating rod 210, and the positioning plate 211 is overlapped on one end of the output shaft 3. A receiving groove 4 is opened inside the output shaft 3, and one end of the rotating rod 210 is located inside the receiving groove 4.

[0029] The effect achieved by the entire embodiment is that the connector 29 is mainly used to limit the position of the movable ring 21 to prevent the movable ring 21 from falling off the output shaft 3. When rotating the threaded rod 24, it is necessary to first remove the bolts connecting the output shaft 3 and the positioning plate 211, and then rotate the rotating rod 210 out of the receiving groove 4 with the connector 29 as the center of the circle. At this time, the threaded rod 24 can be rotated normally to adjust the position of the movable ring 21.

[0030] When the docking block 25 needs to be fixed, the rotating rod 210 is rotated into the receiving groove 4, and the positioning plate 211 is fixed to the output shaft 3 again with bolts.

[0031] The use method and working principle of the device: the output shaft 3 is used to directly replace the central axis of the roller. When docking with the roller, first remove the bolts on the positioning plate 211, then rotate the rotating rod 210 with the joint 29 as the center of the circle to move it out of the receiving groove 4, and then rotate the threaded rod 24 through the rotating rod 210 to drive the movable ring 21 to move along the direction of the output shaft 3;

[0032] During the movement of the movable ring 21, the first support rod 26 will rotate around the protrusion 23 and push the second support rod 27, pushing the docking block 25 away from the output shaft 3, and the movable block 28 will also move along the direction of the T-shaped slide groove 212, thereby achieving the purpose of expanding the overall size, so that the output shaft 3 can be normally connected to the large roller conveyor, ensuring that the output shaft 3 of the reduction motor body 1 can adapt to the large roller conveyor belt.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
