Detailed Description
Referring to fig. 1, a rotator structure is disclosed, in which two housings 20,21 are combined to form a rotator 10, two outer sides of the rotator 10 respectively form a concave slot space 12, and an operation portion 14 is respectively disposed at an outer edge of each concave slot space 12.
Referring to fig. 2 and fig. 1, a three-dimensional exploded view of the rotating body 10 is disclosed, wherein a spindle 30 is disposed at the center of the shells 20 and 21, two ends of the spindle 30 are respectively pivoted with a bearing 34, a rotating rod 32 vertically extends from the center of the spindle 30, one end of the rotating rod 32 different from the end combined with the spindle 30 is provided with a weight block 36, and the length of the rotating rod 32 combined with the weight block 36 is smaller than the radius of the rotating body 10; and a containing groove 22 is respectively arranged inside the shells 20 and 21, two embedding grooves 24 are symmetrically arranged at the central line position of the operating part 14 in each containing groove 22, after the shells 20 and 21 are closed, the mandrel 30 is contained in the containing groove 22, and each bearing 34 is embedded in the corresponding embedding groove 24.
Referring to fig. 2, the housings 20 and 21 are fixed by four positioning members 40, and the four positioning members 40 are disposed at positions adjacent to the upper and lower positions of the operating portion 14, so as to reduce the number of positioning members 40, reduce the weight, and reduce the assembly process.
Continuing to refer to fig. 2, at least one embedded flange 261 and at least one embedded concave edge 262 are respectively disposed on the periphery of the combining surface of the shells 20,21, after the shells 20,21 are covered, each embedded flange 261 is combined with each corresponding embedded concave edge 262, so that the thickness of the shells 20,21 can be reduced, and the overall weight of the rotating body 10 can be reduced; in addition, a plurality of combination protrusions 281 and a plurality of combination recesses 282 are correspondingly disposed inside the housings 20,21, and after the housings 20,21 are covered, each combination protrusion 281 is combined with each combination recess 282 correspondingly disposed, thereby increasing the combination strength of the rotating body 10.
