[0020] Example
[0021] like Figure 1-4 As shown, a 360-degree rotating cover structure for a hand chain hoist includes a hand chain hoist body 1, a cover fixing seat 3, a cover body 5, and a rotating structure. The rotating structure is fixedly connected to the cover body 5. The cover body 5 is detachably fitted onto the positioning structure of the cover fixing seat 3. The cover fixing seat 3 is connected to the hand chain hoist body 1 by several bolts. The positioning structure includes a first protrusion 4 and a second protrusion 7. Both the first protrusion 4 and the second protrusion 7 are fixedly connected to the cover fixing seat 3. The cover body 5 is fitted into the groove formed between the first protrusion 4 and the second protrusion 7.
[0022] The rotating structure includes a rotating bearing outer ring 8, the outer surface of which is fixedly connected to the housing body 5, and the inner surface of which is rolled to the second protrusion 7 via balls 10. A track 11 is provided on the outer surface of the second protrusion 7, and a plurality of balls 10 are provided on the track 11.
