Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

According to the lens rotating structure provided by the embodiment of the utility model, the two ends of the fixed main body are respectively provided with the first outer diameter buckle and the second outer diameter buckle, the rotating ring is sleeved on the fixed main body, and the first inner diameter clamping groove and the second inner diameter clamping groove at the two ends of the rotating ring are respectively clamped with the first outer diameter buckle and the second outer diameter buckle; be provided with the screw hole on the rotatory ring, the locating pin spiro union is in the screw hole and the slot of fixed main part is gone into to the card, and structural design through simple light volume of saving again ensures that rotatory ring also can control its axial deflection effectively when can smoothly rotate.

Fig. 1 is an exploded view of a lens rotation structure according to an embodiment of the present invention, fig. 2 is a schematic view of the lens rotation structure according to the embodiment of the present invention, and fig. 3 is an axial cross-sectional view of the lens rotation structure according to the embodiment of the present invention; as shown in fig. 1 to 3, the lens rotating structure includes: a stationary body 1, a rotating ring 2, and a dowel pin 3.

One end of the fixing main body 1 is provided with a first outer diameter buckle 11, and the other end is provided with a second outer diameter buckle 12, wherein the diameter of the first outer diameter buckle 11 is larger than that of the second outer diameter buckle 12; a groove 13 is also provided around the fixing body adjacent to the second outside diameter snap 12.

The rotating ring 2 is sleeved on the fixed main body 1, one end of the rotating ring 2 is provided with a first inner diameter clamping groove 21, and the other end of the rotating ring is provided with a second inner diameter clamping groove 22; wherein, first internal diameter draw-in groove 21 and the first external diameter buckle 11 looks joint of fixed main part 1, second internal diameter draw-in groove 22 and the second external diameter buckle 12 looks joint of fixed main part 1 for rotatory ring 2 is emboliaing fixed main part 1 after, the structure is in more balanced state, and axle center deviation between them is less, is difficult to appear relative slope and leads to rotatory problem not smooth and easy.
