Abstract:
A screw assembly includes a bolt, a stopping member, and a nut fitted about the bolt. The bolt includes a screw. A side of the screw forms a stopping surface extending along a lengthwise direction of the screw. The stopping member is fitted about the screw. A tab protrudes out from an outer side of the stopping member to abut the stopping surface of the screw to prevent the screw from rotating.

Description:
FIELD 
       [0001]    The present disclosure relates to mounting apparatuses, and more particularly to a mounting apparatus with a screw assembly. 
       BACKGROUND 
       [0002]    An electronic apparatus, such as a server cabinet, usually includes a cabinet and a mounting apparatus for positioning the cabinet to a supporting surface. The installation of the mounting apparatus to the supporting surface typically involves the use of screws and nuts to attach the mounting apparatus. However, the screws with the corresponding nuts tend to rotate together.

     DETAILED DESCRIPTION 
       [0008]    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.” 
         [0009]      FIG. 1  shows an exemplary embodiment of a mounting apparatus  100  for mounting an electronic apparatus  300 . The electronic apparatus  300  comprises a cabinet  302 . Two opposite end walls of a bottom of the cabinet  302  can define a plurality of mounting holes  303 . The mounting apparatus  100  comprises a supporting plate  20 , two connecting members  30 , two shielding members  50 , four screw assemblies  60 , and a plurality of fasteners  70 . 
         [0010]    Two opposite ends of the supporting plate  20  respectively can define two slots  21  extending along a direction perpendicular to a lengthwise direction of the supporting plate  20 . 
         [0011]    Each connecting member  30  can be substantially L-shaped, and comprises a rectangular positioning plate  32  and a connecting plate  33  perpendicularly extending up from a side of the positioning plate  32 . Two opposite ends of the positioning plate  32  can define two bar-shaped positioning holes  322  extending along a lengthwise direction of the positioning plate  32 . A middle of a bottom side of the connecting plate  33  can define a through slot  332  extending along a lengthwise direction of the connecting plate  33 . A top side of the connecting plate  33  can define a plurality of through holes  333  arrayed along the lengthwise direction of the connecting plate  33 . 
         [0012]    Each shielding member  50  comprises a rectangular connecting piece  52  and a shell  53  protruding out from a bottom side of the connecting piece  52 . The shell  53  comprises a top plate  532  extending perpendicularly out from the connecting piece  52 , a side plate  533  extending perpendicularly down from a distal side of the top plate  532 , and two end plates  535  extending perpendicularly down from two opposite ends of the top plate  532  and connected with the side plate  533 . A top of the connecting piece  52  can define a plurality of installation holes  522  arrayed along a lengthwise direction of the connecting piece  52 . 
         [0013]      FIG. 2  shows one screw assembly  60 , the screw assembly  60  comprises a bolt  62 , a stopping member  63 , and a nut  65  fitted about the bolt  62 . The bolt  62  comprises a bar-shaped screw cap  621  and a screw  623  perpendicularly extending up from a middle of the screw cap  621 . A side of the screw  623  forms a stopping surface  625  extending along a lengthwise direction of the screw cap  621 . The screw cap  621  comprises a side surface  622  parallel to the stopping surface  625 . 
         [0014]    The stopping member  63  comprises a D-shaped positioning piece  630  and a substantially L-shaped tab  633  extending down from the positioning piece  630 . A middle of the positioning piece  630  can define a substantially D-shaped locating hole  631 . The locating hole  631  comprises a positioning surface  632  parallel to a straight flange  635  of the positioning piece  630 . The tab  633  comprises an extending portion  636  extending from a middle of the straight flange  635  and a latching portion  637  perpendicularly extending down from a distal end of the extending portion  636 . 
         [0015]      FIGS. 3-5  show that in assembling the mounting apparatus  100 , screws  623  are inserted in the locating holes  631  of the stopping members  63 . The stopping surface  625  of each screw  623  engages with the positioning surface  632  of the corresponding stopping member  63 , and the tab  633  is located adjacent to the corresponding screw cap  621 . Tops of the screws  623  can be rotated in the nuts  65 . The positioning plate  32  of the connecting members  30  can be supported on the supporting plate  20 , and the positioning holes  322  align with the corresponding slots  21 . The screw caps  621  of the screw assemblies  60  can be extended through the positioning holes  322  and the corresponding slots  21 , until the screw caps  621  are exposed from a bottom surface of the supporting plate  20 . The stopping members  63  can be supported on the positioning plates  32 . The screw assembles  60  can be rotated 90 degrees, the screw caps  621  can engage with the bottom surface of the supporting plate  20 , and the tabs  633  can be inserted in the corresponding positioning holes  322 . The nuts  65  can be tightened for fastening the connecting members  30  on the supporting plate  20 . The shells  53  can be supported on the positioning plates  32 , the connecting pieces  52  can engage with the corresponding connecting plates  33 , and the installing holes  522  of each shell  53  can align with the through holes  333  of the corresponding connecting plate  33 . The shell  53  shields the screw assemblies  60 . 
         [0016]      FIG. 6  shows that in use, the cabinet  302  can be supported on the supporting plate  20  and can be located between the shielding members  50 , to allow the end walls of the cabinet  302  to engage with the connecting pieces  52 . The mounting holes  303  can be aligned with the installing holes  522 . The fasteners  70  can extend through the through holes  333  and the installation holes  522 , to be mounted in the corresponding mounting holes  303 . Therefore, the electronic apparatus  300  can be mounted on the supporting plate  20 . 
         [0017]    When disengaging the electronic apparatus  300  from the supporting plate  20 , the nuts  65  can be rotated to be released through the through slots  332 . The stopping members  63  can be moved away from the supporting plate  20 , until the tabs  633  are disengaged from the position holes  322 . The screw assemblies  60  can be rotated through the through slot  332 , until the screw caps  621  align with the corresponding slots  21 . The screw assemblies  60  can be disengaged from the supporting plate  20 . 
         [0018]    It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
