Abstract

A cable management arm includes: a support arm having a connecting portion at both ends separately and at least one chute extended along the support arm; and at least one cable management box having a retaining portion on a side, and movably installed in the chute, and the cable management box including a main body and a cover, and a the main body has a cross-section being a U-shaped structure, and a first pivoting portion and a latching portion disposed at two end portions of an opening of the main body respectively, and the cover having a second pivoting portion corresponsive to the first pivoting portion for pivotally coupling the cover to the main body to cover the opening of the main body, and a locking means for adjusting the position of the cable management box with respect to the support arm all the time.

Claims

1. A cable management arm, comprising:

a support arm, having a connecting portion disposed at both ends of the support arm separately, and at least one chute extended in a direction along the support arm; and

at least one cable management box, having a retaining portion disposed on a side of the cable management box, and movably installed in the chute, and the cable management box including a main body and a cover, and the main body having a cross-section substantially being a U-shaped structure, and a first pivoting portion and a latching portion disposed at two end portions of an opening of the main body respectively, and the cover having a second pivoting portion configured to be corresponsive to the first pivoting portion for pivotally coupling the cover to the main body to cover the opening of the main body, and a locking means for adjusting the position of the cable management box with respect to the support arm all the time,

wherein the locking means has at least one protrusion disposed at the external periphery of the second pivoting portion and corresponsive to the support arm, and a locking effect is achieved after the protrusion and the support arm interfere with each other,

wherein the protrusion is disposed at a position when the cover is closed to 0 degree, and the locking effect is achieved after the cover is closed.

2. The cable management arm according to claim 1, wherein the chute are formed by two parallel through holes, and the retaining portion has two opposite latches configured to be corresponsive to the pair of through holes respectively, and the two latches have a substantially L-shaped cross-section and the openings are formed opposite to each other.

3. The cable management arm according to claim 2, wherein one of the latches is elastic to facilitate installation and operation.

4. The cable management arm according to claim 3, wherein the support arm is corresponsive to the width of the cable management box and bent into a bow shape, and after the cable management box is installed to the support arm, the central axis of the cable management box is aligned linearly with the two end portions of the support arm.

5. The cable management arm according to claim 4, wherein the support arm includes two chutes disposed with an interval apart from each other, and each chute is movably installed with at least one cable management box.

6. The cable management arm according to claim 1, wherein the locking means includes at least one elastic bump disposed on a side of the cable management box opposite to the support arm, and the support arm has a plurality of positioning holes formed on a side of the support arm corresponsive to the elastic bump and disposed with an interval apart from one another, and a locking effect is achieved after one of the elastic bumps is latched to one of the positioning holes.

7. The cable management arm according to claim 5, wherein the locking means includes at least one elastic bump disposed on a side of the cable management box opposite to the support arm, and the support arm has a plurality of positioning holes formed on a side of the support arm corresponsive to the elastic bump and disposed with an interval apart from one another, and a locking effect is achieved after one of the elastic bumps is latched to one of the positioning holes.

8. The cable management arm according to claim 1, wherein the support arm has a reinforcing portion inwardly bent and formed at the top edge and the bottom edge of the support arm separately for increasing the structural strength of the support arm.

9. The cable management arm according to claim 5, wherein the support arm has a reinforcing portion inwardly bent and formed at the top edge and the bottom edge of the support arm separately for increasing the structural strength of the support arm.

10. A cable management arm, comprising:

a support arm, having a connecting portion disposed at both ends of the support arm separately, and at least one chute extended in a direction along the support arm; and

at least one cable management box, having a retaining portion disposed on a side of the cable management box, and movably installed in the chute, and the cable management box including a main body and a cover, and the main body having a cross-section substantially being a U-shaped structure, and a first pivoting portion and a latching portion disposed at two end portions of an opening of the main body respectively, and the cover having a second pivoting portion configured to be corresponsive to the first pivoting portion for pivotally coupling the cover to the main body to cover the opening of the main body, and a locking means for adjusting the position of the cable management box with respect to the support arm all the time,

wherein the locking means has at least one protrusion disposed at the external periphery of the second pivoting portion and corresponsive to the support arm, and a locking effect is achieved after the protrusion and the support arm interfere with each other,

wherein if the protrusion comes with a plural quantity and the protrusions are situated at positions when the cover is opened to 90 degrees and closed to 0 degree, the locking effect will be achieved when the cover is opened and closed respectively.

11. The cable management arm according to claim 10, wherein the chute are formed by two parallel through holes, and the retaining portion has two opposite latches configured to be corresponsive to the pair of through holes respectively, and the two latches have a substantially L-shaped cross-section and the openings are formed opposite to each other.

12. The cable management arm according to claim 11, wherein one of the latches is elastic to facilitate installation and operation.

13. The cable management arm according to claim 12, wherein the support arm is corresponsive to the width of the cable management box and bent into a bow shape, and after the cable management box is installed to the support arm, the central axis of the cable management box is aligned linearly with the two end portions of the support arm.

14. The cable management arm according to claim 13, wherein the support arm includes two chutes disposed with an interval apart from each other, and each chute is movably installed with at least one cable management box.

15. The cable management arm according to claim 10, wherein the locking means includes at least one elastic bump disposed on a side of the cable management box opposite to the support arm, and the support arm has a plurality of positioning holes formed on a side of the support arm corresponsive to the elastic bump and disposed with an interval apart from one another, and a locking effect is achieved after one of the elastic bumps is latched to one of the positioning holes.

16. The cable management arm according to claim 14, wherein the locking means includes at least one elastic bump disposed on a side of the cable management box opposite to the support arm, and the support arm has a plurality of positioning holes formed on a side of the support arm corresponsive to the elastic bump and disposed with an interval apart from one another, and a locking effect is achieved after one of the elastic bumps is latched to one of the positioning holes.

17. The cable management arm according to claim 10, wherein the support arm has a reinforcing portion inwardly bent and formed at the top edge and the bottom edge of the support arm separately for increasing the structural strength of the support arm.
