Abstract

A lens limiting assembly includes a lens assembly ring and a locking ring arranged outside the lens assembly ring. The lens assembly ring includes an accommodating groove. The locking ring includes a body and a hook protruding inwardly from the body and accommodated in the accommodating groove.

First claim

What is claimed is:

1. A lens limiting assembly comprising:
a lens assembly ring including an accommodating groove; and
a locking ring arranged outside the lens assembly ring, the locking ring including:
a body; and
a hook protruding inwardly from the body and accommodated in the accommodating groove.

2. The lens limiting assembly of claim 1 , wherein the hook comprises:
a connecting part connected to an inner wall of the body; and
a bent part, one end of the bent part being connected to the connecting part, and another end of the bent part extending straightly.

3. The lens limiting assembly of claim 2 , further comprising:
an elastic element, wherein the lens assembly ring is arranged on the elastic element.

4. The lens limiting assembly of claim 3 , wherein the lens assembly ring comprises a fitting face arranged on an end face of the lens assembly ring facing the elastic element, the fitting face being inclined in a circumferential direction of the lens assembly ring.

5. The lens limiting assembly of claim 3 , wherein the lens assembly ring includes a limiting part, such that when a lens is rotatably assembled into the lens assembly ring, a snapping body of the lens is held below the limiting part and the elastic element.

6. The lens limiting assembly of claim 3 , wherein the elastic element comprises an elastic body and an elastic arm extending from an inner side of the elastic body.

7. The lens limiting assembly of claim 6 , wherein the locking ring comprises a flange formed at a tail end of the bent part and configured to abut against the elastic arm when the locking ring rotates in one direction.

8. The lens limiting assembly of claim 7 , wherein the flange is configured to be accommodated in a gap formed between the elastic arm and the elastic body.

9. The lens limiting assembly of claim 7 , wherein the flange comprises an inclined surface formed on a side of the flange facing the connecting part, the inclined surface connecting the flange and the bent part.

10. A camera body comprising:
a fixing frame having a contact base mounting position; and
a lens limiting assembly mounted on the contact base mounting position and including:
a lens assembly ring including an accommodating groove; and
a locking ring arranged outside the lens assembly ring, the locking ring including:
a body; and
a hook protruding inwardly from the body and accommodated in the accommodating groove.

11. The camera body of claim 10 , wherein the lens limiting assembly further comprises:
an elastic element, wherein the lens assembly ring is arranged on the elastic element.

12. A camera comprising:
a lens;
a camera body configured to receive the lens; and
a lens limiting assembly arranged on the camera body and including:
a lens assembly ring including an accommodating groove; and
a locking ring arranged outside the lens assembly ring, the locking ring including:
a body; and
a hook protruding inwardly from the body and accommodated in the accommodating groove.

13. The camera of claim 12 , wherein the hook comprises:
a connecting part connected to an inner wall of the body; and
a bent part, one end of the bent part being connected to the connecting part, and another end of the bent part extending straightly.

14. The camera of claim 13 , wherein the lens limiting assembly further comprises:
an elastic element, wherein the lens assembly ring is arranged on the elastic element.

15. The camera of claim 14 , wherein the lens assembly ring comprises a fitting face arranged on an end face of the lens assembly ring facing the elastic element, the fitting face being inclined in a circumferential direction of the lens assembly ring.

16. The camera of claim 14 , wherein the lens assembly ring includes a limiting part, such that when the lens is rotatably assembled into the lens assembly ring, a snapping body of the lens is held below the limiting part and the elastic element.

17. The camera of claim 14 , wherein the elastic element comprises an elastic body and an elastic arm extending from an inner side of the elastic body.

18. The camera of claim 17 , wherein the locking ring comprises a flange formed at a tail end of the bent part and configured to abut against the elastic arm when the locking ring rotates in one direction.

19. The camera of claim 18 , wherein the flange is configured to be accommodated in a gap formed between the elastic arm and the elastic body.

20. The camera of claim 18 , wherein the flange comprises an inclined surface formed on a side of the flange facing the connecting part, the inclined surface connecting the flange and the bent part.
