Abstract:
A support stand includes a base, a suction assembly, and a connecting plate. The suction assembly includes a suction cup, a receiving seat, and an adjusting member. The suction cup forms a connecting shaft. The connecting shaft extends through the base and engages with the adjusting member, thus positioning the suction cup in the receiving seat. The connecting plate connects the suction assembly to the base. A display device using the support stand is also provided.

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates generally to device support and, more particularly, to a support stand for a display device. 
         [0003]    2. Description of Related Art 
         [0004]    The tilt angle of an LCD panel of an LCD device can often be adjusted via a support stand. 
         [0005]    Such a support stand often includes a base, a connecting plate, a connecting seat, a first hinge, and a second hinge. The connecting seat is rotatably connected to the connecting plate via the first hinge, and the connecting plate is rotatably connected to the base via the second hinge. The connecting seat is connected to a fixing portion of the LCD panel via a plurality of fasteners. 
         [0006]    However, in assembly/disassembly of the LCD panel to the connecting seat, each of the fasteners must be individually adjusted. In addition, the LCD panel needs the fixing portion corresponding to the connecting seat. Therefore, the support stand has a complex structure. 
         [0007]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0012]    Referring to  FIG. 1 , an embodiment of a display device  100  includes a support stand  30  and a display panel  50 . In the illustrated embodiment, the display panel is an LCD panel. 
         [0013]    Referring to  FIGS. 2 and 3 , the support stand  30  includes a base  31 , a connecting plate  32 , a suction assembly  33 , a first hinge  34 , and a second hinge  35 . 
         [0014]    The base  31  includes a bottom plate  311  and a support portion  312  extending upwards from a center portion of the bottom plate  311 . A restricting portion  313  is formed on a top end of the support portion  312 . The restricting portion  313  defines a through hole  3131 . In the illustrated embodiment, the bottom plate  311  is a substantially circular plate. 
         [0015]    The connecting plate  32  includes a substantially rectangular main portion  321  and two pairs of connecting portions  322  extending outwardly from two opposite edges of the main portion  321 , respectively. Each pair of connecting portions  322  faces each other and defines a connecting hole  3221  substantially coaxial with each other. 
         [0016]    The suction assembly  33  includes a suction cup  331 , a receiving seat  332 , a washer  333 , and an adjusting member  334 . The suction cup  331  includes a substantially hemispherical suction portion  3311  and a spacer portion  3312  extending from the suction portion  3312 . A connecting shaft  3313  is formed at an end of the spacer portion  3312  away from the suction portion  3311 . In the illustrated embodiment, the suction cup  331  is made of silicone rubber. The connecting shaft  3313  forms a plurality of threads. The receiving seat  332  includes a substantially hemispherical receiving portion  3321  corresponding to the suction portion  3311 , a radius of which is less than that of the suction portion  3311 . A tip of the receiving portion  3321  defines an assembly hole  3322 . The receiving seat  332  further forms a support pole  3323  adjacent to the assembly hole  3322 . The support pole  3323  defines a through hole  3324  at an end away from the receiving portion  3321 . In the illustrated embodiment, the washer  333  is a substantially circular washer, and the adjusting member  334  is a threaded retainer. 
         [0017]    The first hinge  34  includes a first shaft  341  and a first fastener  342 . A shaft cap  3411  and a threaded portion  3412  are formed on opposite ends of the first shaft  341 . In the illustrated embodiment, the first fastener  342  is a threaded retainer. 
         [0018]    The second hinge  35  includes a first shaft  351  and a first fastener  352 . A shaft cap  3511  and a threaded portion  3512  are formed on opposite ends of the second shaft  351 . In the illustrated embodiment, the second fastener  352  is a threaded retainer. 
         [0019]    In assembly of the support stand  30 , the first shaft  341  extends through the connecting hole  3221  of one connecting portion  322 , the through hole  3131  of the restricting portion  313 , and the connecting hole  3221  of another connecting portion  322 . The first fastener  342  is assembled on the threaded portion  3412  of the first shaft  341  such that the connecting plate  32  is connected to the base  31 . The second shaft  351  extends through the connecting hole  3221  of one connecting portion  322 , the through hole  3324  of the support pole  3323 , and the connecting hole  3221  of another connecting portion  322 . The second fastener  352  is assembled on the threaded portion  3512  of the second shaft  351  such that the receiving seat  332  is connected to the connecting plate  32 . The connecting shaft  3313  of the suction cup  331  extends through the assembly hole  3322  of the receiving seat  332 , the washer  333 , and the adjusting member  334 . The suction cup  331  can be positioned in the receiving seat  332  by rotating the adjusting member  334 . 
         [0020]    In assembly of the display device  100 , the display panel  50  is attached to the suction cup  331 . Then the adjusting member  334  is rotated such that the connecting shaft  3313  pulls the suction portion  3311  to expand towards the tip of the receiving portion  3321 . Thus, air pressure in the suction portion  3311  is lower than that of outside. The display panel  50  is positioned on the support stand  30  via a suction force generated by the air pressure difference between inside and outside the suction portion  3311 . The suction cup  331  can fix display panels  50  with different weights by rotation of the adjusting member  334 . 
         [0021]    In use, a tilt angle of the display panel  50  can be adjusted by rotating the first and second fasteners  342 ,  352  to loosen the first and second shafts  341 ,  351 , and then rotating the connecting plate  32  and the support pole  3323 . After the display panel  50  is adjusted to a desired tilt angle, the first and second fasteners  342 ,  352  are rotated to lock the first and second shafts  341 ,  351 . In disassembly of the display panel  50  from the support stand  30 , the adjusting member  334  is rotated to eliminate suction force of the suction cup  331 . Finally, the display panel  50  is disassembled from the suction cup  331 . 
         [0022]    The support stand  30  grasps the display panel  50  tightly by the suction cup  331 , and the display panel  50  is assembled/disassembled by rotation of the adjusting member  334 , thus the support stand  30  has a simple structure and operates easily. It should be appreciated that the base  31 , the first hinge  34 , and the second hinge  35  may have other structures, such as, for example, the first hinge  34  further comprises an elastic member sleeved on the first shaft  341 . 
         [0023]    It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages.
