Abstract

An electronic enclosure includes a base, a cover mounted on the base, a first locking module engaged on the cover, a second locking module, and a locking structure. The base defines a number of supporting recesses defined therein. The cover includes a number of barbs for matching with the supporting recesses of the base. The second locking module includes at least one locking member. The at least one locking member includes a pivot portion pivotably engaging with the base, a first end and a second end opposite to the first end. The locking structure abuts the first end of the at least one locking member to rotate the second end to engage with the first locking module, whereby the cover is fixed on the base.

Claims

1. A locking device for an enclosure having a base and a cover mounted on the base, the locking device comprising:

a locking module comprising at least one locking member, the at least one locking member comprising a pivot portion for pivotably engaging with the base, a clasping portion extending from an end of the pivot portion, and a supporting portion extending from the other end of the pivot portion; and

a locking structure abutting the supporting portion of the at least one locking member to rotate the clasping portion to engage with the cover, whereby the cover is fixed on the base.

2. The locking device of claim 1, further comprising an elastic member connecting the at least one locking member and the base, wherein when the locking structure disengages with the supporting portion, the elastic member forces the clasping portion to disengage with the cover.

3. The locking device of claim 1, further comprising a number of supporting recesses defined in the base, and a number of barbs extending from the cover for matching with the supporting recesses of the base.

4. The locking device of claim 1, further comprising an additional locking member comprising a pivot portion for pivotably engaging with the base, a clasping portion extending from an end of the pivot portion for engaging the cover, and an inserting portion extending from the other end of the pivot portion to engage with the at least one locking member.

5. The locking device of claim 1, wherein the locking structure is a lock for engaging the cover and the base.

6. The locking device of claim 1, further comprising an additional locking module engaging with the cover, the additional locking module comprising a resisting portion to engage with the clasping portion of the at least one locking member.

7. The locking device of claim 6, wherein the additional locking module comprises a main body, an operation portion extending through the cover and connected with the main body, and a flexible member abutting between the main body and the cover.

8. An electronic enclosure, comprising:

a base with a number of supporting recesses defined therein;

a cover mounted on the base, the cover comprising a number of barbs for matching with the supporting recesses of the base;

a locking module comprising a first locking member and a second locking member, the first locking member comprising a pivot portion pivotably engaging with the base, a first end and a second end opposite to the first end, the second locking member comprising a pivot portion pivotably engaging with the base, a first end engaged with the first end of the first locking member and a second end opposite to the first end of the second locking member; and

a locking structure abutting the first end of the first locking member to rotate the second ends of the first and second locking members to engage with the first locking module, whereby the cover is fixed on the base.

9. The electronic enclosure of claim 8, wherein a pressing portion extending from a bottom of the first end of the first locking member, an inserting portion extending from first end of the second locking member to engage with the pressing portion of the first locking member.

10. The electronic enclosure of claim 8, wherein the base comprises a baffle and a supporting plate extending from a top edge of the baffle, the first and second locking members are pivotably engaged with the baffle.

11. The electronic enclosure of claim 10, wherein the first locking member extends a supporting portion from the first end thereof to insert into the baffle, the locking structure extending through the supporting plate and abutting the supporting portion of the first locking member.

12. The electronic enclosure of claim 10, wherein the second locking member extends a supporting portion to insert into the baffle, an elastic member connecting the supporting portion of the second locking member and the baffle.

13. An electronic enclosure, comprising:

a base with a number of supporting recesses defined therein;

a cover mounted on the base, the cover comprising a number of barbs for matching with the supporting recesses of the base;

a first locking module engaged on the cover;

a second locking module comprising at least one locking member, the at least one locking member comprising a pivot portion for pivotably engaging with the base, a first end and a second end opposite to the first end; and

a locking structure abutting the first end of the at least one locking member to rotate the second end to engage with the first locking module, whereby the cover is fixed on the base.

14. The electronic enclosure of claim 13, wherein the second locking module further comprises an elastic member connecting the at least one locking member and the base, when the locking structure disengages with the first end of the at least one locking member, the elastic member forces the clasping portion to disengage with the cover.

15. The electronic enclosure of claim 13, wherein the second locking module comprising an additional locking member, the additional locking member comprising a pivot portion for pivotably engaging with the base, a first end engaging with the at least one locking member, and a second end engaging with the first locking module.

16. The electronic enclosure of claim 13, wherein the locking structure is a lock for engaging with the cover and the base.

17. The electronic enclosure of claim 13, wherein the first locking module comprises a main body to engage with the clasping portion of the at least one locking member, an operation portion extending through the cover and connected with the main body, and a flexible member abutting between the main body and the cover.
