Claims

1. An optical lens barrel structure, comprising: A positioning bracket for mounting above an image sensing element; A mirror tube component is mounted on the positioning base component; And an adhesive to bond the lens barrel to the positioning seat.

2. The optical lens barrel structure as claimed in claim 1, wherein the positioning seat is a plastic positioning seat and the lens barrel is a plastic lens barrel.

3. The optical lens barrel structure as described in claim 2, wherein the adhesive is a UV-curable adhesive.

4. The optical lens barrel structure as claimed in claim 1, wherein the material of the lens barrel is thermoplastic.

5. The optical lens barrel structure as claimed in claim 4, wherein the material of the lens barrel contains glass fiber, carbon fiber, mineral fiber, or a combination thereof.

6. The optical lens barrel structure as claimed in claim 1, wherein the roundness of the inner sidewall of the lens barrel is less than 0.005 mm.

7. The optical lens barrel structure as claimed in claim 1, wherein the lens barrel has a light-transmitting hole located on an optical axis of the lens barrel and on the side of the lens barrel away from the positioning seat, and the roundness of the light-transmitting hole is less than 0.01 mm.

8. The optical lens barrel structure as claimed in claim 1, wherein the outer surface of the lens barrel has a physical vapor deposition film.
