Abstract

An exemplary lid lock mechanism (20) includes a main body (22) and a lid (24). Two resilient hooks (222) and two resisting portions (224) are formed on an inner surface of the main body. The lid includes a lid cap (242). Two hooking portions (246) and two extending pieces (248) are formed on a surface (244) of the lid cap. The hooking portions are engaged with the resilient hooks of the main body when the lid is connected to the main body. To detach the lid from the main body, the hooks of the hooking portions are disengaged from the resilient hooks of the main body.

Claims

1. A lid lock mechanism comprising:

a main body having an opening and at least one resilient hook being formed on an inner surface of the main body;

a lid for connecting to the main body, the lid having a lid cap for matching with the opening of the main body, at least one hooking portion, at least one resilient member and at least one extending piece being formed on a same surface of the lid cap, and the at least one hooking portion including a hook formed at an end thereof; and

wherein when the lid is pressed to connect to the main body, the at least one hooking portion of the lid is engaged with the at least one resilient hook of the main body after passing through the at least one resilient hook along a first direction, when the lid is pressed to be detached from the main body, the at least one extending piece pushes the at least one resilient hook to bend, such that the hook of the at least one hooking portion is disengaged from the at least one resilient hook of the main body and passes through the at least one resilient hook along a second direction opposite to the first direction.

2. The lid lock mechanism as claimed in claim 1, wherein at least one resisting portion is formed on an inner surface of the main body, the at least one resisting portion is configured to resist the at least one resilient member of the lid.

3. The lid lock mechanism as claimed in claim 1, wherein the at least one resilient member is a resilient piece.

4. The lid lock mechanism as claimed in claim 1, wherein the at least one resilient member is a spring with an end fixed to the lid.

5. The lid lock mechanism as claimed in claim 1, wherein a distance between the hook of the at least one hooking portion and an inner surface of the main body is smaller than a distance between the end of the at least one resilient hook and the inner surface of the main body.

6. The lid lock mechanism as claimed in claim 5, wherein a length of the hooking portions is larger than a length of the extending pieces plus a thickness of the resilient hooks.

7. The lid lock mechanism as claimed in claim 1, wherein an exposing end of the at least resilient hook includes a hook end, the hook end is configured to be engaged with the hook of the at least one hooking portion.

8. The lid lock mechanism as claimed in claim 1, wherein the hook of the at least one hooking portion passes through the at least one resilient hook along a first direction, with the hook of the at least one hooking portion engaging with the at least one resilient hook of the main body, and the at least one resilient member is prevented by the at least one extending piece from bending along a second direction opposite to the first direction, such that the lid is latched to the main body.

9. The lid lock mechanism as claimed in claim 1, wherein a shape and size of the lid cap corresponds to that of the opening of the main body.

10. The lid lock mechanism as claimed in claim 1, wherein the at least one resilient hook is two resilient hooks, the at least one hooking portion is two hooking portions, and the at least one extending piece is two extending pieces.

11. The lid lock mechanism as claimed in claim 10, wherein the two resilient hooks, the two hooking portions, and the two extending pieces are respectively aligned mirroring each other.

12. The lid lock mechanism as claimed in claim 1, wherein the opening of the main body is circular, and the lid cap of the lid is circular correspondingly.

13. A lid lock mechanism comprising:

a first member having an opening, at least one resilient hook being formed on an inner surface of the first member, the at least one resilient hook being bendable; and

a second member for connecting to the first member, at least one hooking portion, at least one resilient member and at least one extending piece being formed on a same surface of the second member, and the at least one hooking portion including a hook formed at an end thereof, the hook of at least one hooking portion configured for engaging with the at least one resilient hook of the first member when the second member is connected to the first member, the at least one extending piece configured for pushing the at least one resilient hook of the first member to bend when the second member is detached from the second member.

14. The lid lock mechanism as claimed in claim 13, wherein at least one resisting portion is formed on an inner surface of the first member, the at least one resisting portion is configured to resist the at least one resilient member of the second member.
