1. Field of the Invention
The present invention relates to a retractable electrical casing structure, in particular to a hollow casing having sliding members and a sliding bracket having sliding sections. The sliding bracket is able to retract or to expand with respect to the casing.
2. Description of the Prior Art
A conventional electronic casing, as shown in
It is the primary objective of the present invention to provide a retractable electrical casing structure, which has a compact variable size that saves storage room and space.
It is another objective of the present invention to provide a retractable electrical casing structure, which is easy to stack together for shipment and saves shipping cost.
It is a further objective of the present invention to provide a retractable electrical casing structure, which can be retracted to a compact size that will not cause deformation when stacking together.
As shown in
The casing 1 has a hollow body having a pair of locating plates 11 at opposite inner sides thereof. Each locating plate 11 has a pair of locating holes 12 thereon for insertion of sliding members 13. The sliding member 13 may be a stud. Each locating plate 11 is provided with two locating blocks 14 between the two locating holes 12. The casing 1 has a number of threaded holes 15 on its edge. A cover 16 is provided with a number of through holes 17 corresponding in position to the threaded holes 15. The cover 16 is secured onto the casing 1 by inserting fasteners 18 into the through holes 17 and the threaded holes 15.
The sliding bracket 2 is mounted to the casing 1, and comprises a bottom board 24 and a pair of locating plates 21 at two sides. The bottom board 24 is secured to the locating plates 21. Each locating plate 21 has a pair of sliding sections 22. The sliding sections 22 are slots for the sliding members 13 to slide therealong. Each locating plate 21 is provided with two locating slots 23 between the two sliding sections 22 for engagement of the locating blocks 14.
