DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
FIG. 1 and FIG. 2 illustrate one embodiment of an enclosure. The enclosure includes a chassis 20, a locking member 30 attached to the chassis 20, a top panel 40, a detaching member 51, and a mounting member 53.
The chassis 10 includes a bottom wall 21, a front wall 23, a rear wall 25, a first sidewall 27, and a second sidewall 29. A rear flange 251 is located on a top edge of the rear wall 21. Referring also to FIG. 4, the rear wall 21 defines two locking holes 253. Two lifting portions 257 and two bridges 255 are located on an inner side of the rear wall 25. The rear wall 21 defines a recess 2511 at a top edge thereof.
In one embodiment, the locking member 30 is linear. The locking member 30 includes a pressing portion 31, two engaging portions 33 at two sides of the pressing portion 31, and two hooking ends 35 located at two free distal ends of the engaging portions 33. The locking member 30 is resilient.
A locking flange 43 is located on a side of the top panel 40. The locking flange 43 is substantially perpendicular to the panel 40. Two hooks 431 are located on the locking flange 43, and extend towards a direction substantially perpendicular to the locking flange 43. The top panel 40 defines a recess portion 41. The recess portion 41 defines a through opening 413. Four fixing portions 4111 are located on a bottom side of the recess portion 41.
The detaching member 51 includes an operating portion 511, a tab 513, and a connecting portion 515 connecting the operating portion 511 and the tab 513. The tab 513 is located in a plane substantially parallel to the operating portion 511. Two pivot holes 5151 are located on the connecting portion 511.
A mounting member 53 defines a cutout 533 and four mounting holes 531. A pair of pivot portions 537 is located in the mounting member 53.
FIG. 3 illustrates an assembly of the mounting member 53 and the detaching member 51 to the top panel 40. The mounting member 53 is fixed to the bottom side of the recess portion 41 with the fixing portions 4111 interferingly engaged in the mounting holes 531 of the mounting member 53. The cutout 533 is aligned with the through opening 413. The detecting member 51 is located in the recess portion 41 with the tab 513 extending through the through opening 413. The pivot holes 5151 are aligned with the pivot portions 537. A pivot shaft 55 extends through the pivot holes 5151 and the pivot portions 537 with a coil spring 57 surrounding on the pivot shaft 55. The detaching member 51 then can be rotated about the pivot shaft 55.
Referring through FIG. 4 to FIG. 6, when assembling the chassis 20 and locking member 30, two hooking portions 35 are clasped on the two bridges 255. The engaging portions 33 are located on the lifting portions 257. The pressing portion 31 protrudes from a bottom portion of the recess 2511.
When assembling the top panel 40 to the chassis 20, the top panel 40 covers on the chassis 20 with the locking flange 43 located on a back side of the rear wall 25. The top panel 40 is moved towards the chassis 20. The hooks 431 extend into the corresponding locking holes 253 and hook the engaging portions 33 of the locking member 30. The tab 513 of the detaching member 51 is located in the recess 2511. The hooks 431 can prevent the top panel 40 from moving out of the chassis 20.
When detaching the top panel 40 from the chassis 20, the operating portion 511 is pulled upward. The tab 513 pushes the pressing portion 31 down to lift the engaging portions 33 away from the pressing portion 31 urged on the lifting portions 257. The engaging portions 33 are disengaged from the hooks 431. The top panel 40 with the hooks 431 is moved out of the chassis 20. The top panel 40 is detached from the chassis 20.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
