DETAILED DESCRIPTION
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
FIGS. 1 and 2 illustrate a server case 100 includes a shell 10, a door 20 and two connection members 30. The shell 10 defines an opening 12. FIG. 3 illustrates the connection member 30 includes a sliding portion 32 and a rotation portion 34. The sliding portion 32 is slidable and connects to the door 20. The rotation portion 34 is slidably engaged with the shell 10. When the sliding portion 32 slides on the door 20 from a first position to a second position, the rotation portion 34 slides in the shell 10 from a first position to a second position to drive the door 20 from a first state in which the door 20 is supported at an angle between the door 20 and the opening 12 greater than 90 degrees to a second state in which the door shields the opening 12.
The door 20 includes two opposite first flanges 22 and two opposite second flanges 24 connecting the two opposite first flanges 22. The first flange 22 is parallel to the opening 12. FIGS. 4 and 5 illustrate a sliding groove 26 is defined at an inner side of the door 20. An extended direction of the sliding groove 26 is parallel to the second flange 24. The sliding groove 26 is “U” shaped. A stop member 28 protrudes from the door 20 and is adjacent to the sliding groove 26. FIGS. 3 and 6 illustrate the sliding portion 32 defines a restriction groove 33 parallel to the sliding groove 26. The sliding portion 32 is slidable and received in the sliding groove 26. The stop member 28 is received in the restriction groove 33.
The rotation portion 34 is perpendicularly attached to the sliding portion 32. The rotation portion 34 defines an arc rotation groove 35. The rotation groove 35 includes a start end 37 adjacent to the sliding portion 32 and a distal end away from the sliding portion 39. The start end 37 is positioned above the distal end 39.
Two rotation shafts 14 are attached to the shell 10. The rotation shaft 14 is perpendicular to the rotation groove 35 and is received in the rotation groove 35. When the door 20 is supported in the first state, the stop member 28 is received in an end of the restriction groove 33 away from the shell 10, the rotation shaft 14 is received in the distal end 39 of the rotation groove 35. Therefore, the angle between the door 20 and the opening 12 cannot continue to increase under a pulling force of the sliding portion 32 and the rotation shaft 14. The door 20 is supported in the first state. FIGS. 7 and 8 illustrate when shielding the opening 12, the door 20 is rotated, the rotation portion 32 slides in the sliding groove 26 to move the stop member 28 from the end of the sliding groove 26 away from the shell 10 to the other end of the sliding groove 26. Correspondingly, the rotation portion 34 engages with the shell 10 to move the rotation shaft 14 from the distal end 39 of the rotation shaft 35 to the start end 37 of the rotation groove 35 to pull the door 20 to shield the opening 12.
The shell 10 further defines a threaded hole 16. The door 20 defines a through hole 25. When the door 20 shields the opening 12, a bolt 50 passes through the through hole 25 to screw in the threaded hole 16 to secure the door 20 to the shell 10.
FIGS. 9 and 10 illustrate the shell 10 further defines two first slots 15 and two second slots 17 positioned above the two first slots 15. The rotation shaft 14 is positioned between the first slot 15 and the second slot 17. The rotation shaft 14 includes a fixing end 141 fixed to the shell 10 and a free end 143. The free end 143 projects in a direction perpendicular to the first slot 15 and is within the first slot 15, and a distance between the free end 143 and a lateral edge 151 of the first slot 15 away from the fixing end 141 is less than the thickness of the rotation portion 34. Therefore, the rotation shaft 14 prevents the rotation portion 34 from moving away from the first slot 15. A protrusion 31 protrudes from the rotation portion 34. The protrusion 31 defines a gap 36. The gap 36 is opposite to the rotation shaft 14 and communicates with the rotation groove 35. When assembling the rotation portion 34, an end of the rotation portion 34 adjacent to the distal end 39 passes through the second slot 17 to be received in an end of the first slot 15 away from the sliding portion 32, to align gap 36 with the rotation shaft 14, the rotation portion 34 is moved toward the sliding portion 32 to make the rotation shaft 14 cross the gap 36 to be received in the rotation groove 35. Therefore, the rotation portion 34 sleeves on the rotation shaft 14.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
