Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-6, a pointer display structure based on a planetary gear in this embodiment includes a main structural plate 1, a fixed gear 3 and an indication scale 8 are fixed on the front surface of the main structural plate 1, a driving shaft 2 is rotatably connected to the front surface of the main structural plate 1, a connecting rod 4 is fixed on the outer surface of the driving shaft 2, a planetary carrier 5 and a planetary indication gear 6 are rotatably connected to the back of the connecting rod 4, and an indication needle 7 is fixed on the front surface of the planetary indication gear 6.

Wherein, fixed gear 3 meshes with planet carrier wheel 5, and planet carrier wheel 5 meshes with planet indicating gear 6 mutually, drives connecting rod 4 through drive shaft 2 and rotates, and connecting rod 4 drives planet carrier wheel 5 and rotate together to drive planet indicating gear 6 through planet carrier wheel 5 and rotate together, fixed gear 3 and planet indicating gear 6's gear ratio is 2:1, the center of the fixed gear 3 is coincided with the driving shaft 2, so that when the connecting rod 4 drives the planetary carrier 5 to rotate, the planetary carrier 5 can rotate through the meshed fixed gear 3.

When the length of the pointer 7 is shorter than the distance from the center of the drive shaft 2 to the center of the planetary gear 6, the locus of the tip of the pointer 7 is an elliptical arc, the pointer shaft or the hour hand shaft in the wristwatch is used as the drive shaft 2, the tip of the pointer 7 moves along the elliptical locus, and when the length of the pointer 7 is the same as the distance from the center of the drive shaft 2 to the center of the planetary gear 6, the locus of the tip of the pointer 7 is a straight line, and the reverse jump pointer shaft in the wristwatch is used as the drive shaft 2, and the tip of the pointer 7 moves in the straight line locus and jumps reversely.
