Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0037] Please refer to Figures 1-4 , the embodiments provided by the present utility model:

[0038] An eccentric turntable with adjustable radius, including a transportation turntable frame 2. One end of the transportation turntable frame 2 rotates on the inner guide rail 1, and the other end of the transportation turntable frame 2 rotates on the outer guide rail 3. The transportation turntable frame 2 of the eccentric turntable moves along the outer guide rail 3 with the annular inner guide rail 1 as the center, so as to be able to transport goods at a certain angle.

[0039] The transportation turntable frame 2 includes a first turntable frame 21 and a second turntable frame 22. The length of the transportation turntable frame 2 is adjusted by the extended length of the telescopic assembly 4, and the radius between the inner guide rail 1 and the outer guide rail 3 is changed by the extended length of the telescopic assembly 4 on the first turntable frame 21 and the second turntable frame 22.

[0040] Specifically, the telescopic assembly 4 includes a sliding plate 41, a mounting plate 42, and sliding blocks 43. The middle bottom surface of the sliding plate 41 is welded to the mounting plate 42. The two end side walls of the sliding plate 41 are respectively fixedly connected with sliding blocks 43. Chute grooves 24 are formed on the side walls of the first rotating frame 21 and the second rotating frame 22. The sliding blocks 43 are slidably connected in the chute grooves 24. The sliding plate 41 slides in the chute grooves 24 formed on the side walls of the first rotating frame 21 and the second rotating frame 22 respectively, so as to be able to extend the length between the first rotating frame 21 and the second rotating frame 22, and further be able to adjust the diameter size between the outer guide rail 3 and the inner guide rail 1. When building the eccentric turntable, after the outer guide rail 3 and the inner guide rail 1 are pre-installed according to the scene requirements, the extending length of the sliding plate 41 between the first rotating frame 21 and the second rotating frame 22 is adjusted according to the required radius size, so as to facilitate adjusting the radius of the eccentric turntable according to the actual requirements.

[0041] Furthermore, limiting grooves 23 are respectively formed on the side walls of the first rotating frame 21 and the second rotating frame 22 and on both sides of the chute groove 24. A limiting plate 44 is installed on the side wall of the sliding block 43. Protrusions are provided at both ends of the limiting plate 44. The protrusions are slidably connected in the limiting grooves 23. By the sliding of the sliding blocks 43 and the limiting plates 44 in the chute grooves 24 and the limiting grooves 23 respectively, the connection between the first rotating frame 21, the second rotating frame 22, and the sliding plate 41 is ensured to be tight and not easy to shift.

[0042] A driving assembly 5 is installed on the bottom surface of the telescopic assembly 4. The driving assembly 5 includes a bearing seat 51, a lead screw 52, a moving seat 53, a first support 54, a rotating rod 55, and a second support 56. The bearing seat 51 is installed on the bottom surface of the mounting plate 42. The top end of the lead screw 52 is fixedly installed with the inner ring of the bearing seat 51. A threaded groove is formed inside the moving seat 53. The moving seat 53 is threadedly connected with the side wall of the lead screw 52 through the threaded groove inside. The first supports 54 are respectively arranged on both side walls of the moving seat 53. The second supports 56 are respectively welded to the bottom surfaces of the first rotating frame 21 and the second rotating frame 22. The two ends of the rotating rod 55 are respectively rotatably connected with the first supports 54 and the second supports 56 through fixed shafts. A sheet metal part is welded to the top surface of the mounting plate 42. The side wall of the sheet metal part is welded to the side wall of the sliding plate 41;

[0043] When it is necessary to adjust the distance between the first rotating frame 21 and the second rotating frame 22, the lead screw 52 is rotated on the bearing seat 51, so that the moving seat 53 rises or falls on the side wall of the lead screw 52. During the rising or falling process, the rotating rod 55 on the side wall is driven to rotate through the first support 54. During the rotation of the rotating rod 55, an outward acting force is generated, so as to drive the first rotating frame 21 and the second rotating frame 22 to move outward or inward, and enable the sliding blocks 43 and the limiting plates 44 on the sliding plate 41 to slide in the chute grooves 24 and the limiting grooves 23 respectively.

[0044] The side wall of the driving assembly 5 is provided with a transmission assembly 6. There are two sets of driving assemblies 5. The first rotating frame 21 and the second rotating frame 22 both have two cross beams. The driving assemblies 5 are respectively installed on the bottom surfaces of the cross beams. The transmission assembly 6 includes a driving sprocket 61, a chain 62 and a driven sprocket 63. There are two lead screws 52. The bottom end of one of the lead screws 52 is fixedly installed with a runner 7. The side wall of this lead screw 52 is key-connected to the inside of the driving sprocket 61. The side wall of the driving sprocket 61 is drivingly connected to the driven sprocket 63 through the chain 62. The inside of the driven sprocket 63 is key-connected to the side wall of the other lead screw 52.

[0045] By manually rotating the runner 7, the lead screw 52 drives the driving sprocket 61 to rotate. Under the drive of the chain 62, the driven sprocket 63 rotates, so that the two lead screws 52 can rotate synchronously, thereby synchronously adjusting the up and down movement of the two moving seats 53, so as to ensure that the distance between the two cross beams of the first rotating frame 21 and the second rotating frame 22 is the same, so as to prevent the transport rotating frame 2 from extending or shortening and causing deviation.

[0046] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
