Monitor stand and monitor apparatus thereof

Abstract

A screen bracket includes a support column, a cantilever extending from the support column, and a torque adjustment mechanism. The torque adjustment mechanism includes first and second torsion springs, a pivot shaft, and a switching button. The pivot shaft is pivotally connected between the cantilever and a display screen. The first torsion spring is sleeved on the pivot shaft and has first and second protruding arm portions, the first protruding arm portion being fixed to the display screen. The second torsion spring is sleeved on the pivot shaft and has third and fourth protruding arm portions, the third protruding arm portion being fixed to the display screen. The switching button is movably disposed on the cantilever so that when moved to a first position, it stops the second protruding arm portion and disengages from the fourth protruding arm portion, allowing the first torsion spring to provide torque to the display screen; and when moved to a second position, it stops the second and fourth protruding arm portions, allowing the first and second torsion springs to jointly provide torque to the display screen.

Claims

1. A screen bracket suitable for connecting a display screen, the screen bracket comprising: a support column; a cantilever connected to the support column and suspended extending from the support column; and a torque adjustment mechanism comprising: a pivot shaft pivotally connected between the cantilever and the display screen, such that the display screen is pivotable relative to the cantilever; and a first torsion spring sleeved on the pivot shaft and having a first protruding arm portion and a second protruding arm portion, the first protruding arm portion being fixedly connected to the display screen; A second torsion spring is sleeved on the pivot shaft and has a third protruding arm and a fourth protruding arm, the third protruding arm being fixed to the display screen; and a switching button having a knob, a stop post, and a groove-shaped limiting structure. The knob is rotatably disposed on the cantilever to be operablely moved to a first position or a second position. The stop post protrudes from the center of the knob toward the pivot shaft, and the groove-shaped limiting structure protrudes from the knob toward the pivot shaft and is adjacent to one side of the stop post. When the knob is rotated to the first position, the stop post stops the second protruding arm, so that the first torsion spring provides torque to the display screen. When the knob is rotated to the second position, the stop post stops the second protruding arm, and the fourth protruding arm engages with the groove-shaped limiting structure, so that the first and second torsion springs together provide torque to the display screen.

2. The screen bracket as described in claim 1, wherein the first torsion spring and the second torsion spring are sleeved on the pivot axis in a side-by-side manner.

3. The screen bracket as claimed in claim 1, wherein one of the first torsion spring and the second torsion spring is sleeved on the pivot axis, and the other of the first torsion spring and the second torsion spring is sleeved on the first torsion spring and the second torsion spring.

4. A screen device comprising: a display screen; and a screen bracket connected to the display screen, the screen bracket comprising: a support column; a cantilever connected to the support column and suspended extending from the support column; and a torque adjustment mechanism comprising: a pivot shaft pivotally connected between the cantilever and the display screen, such that the display screen is pivotable relative to the cantilever; and a first torsion spring sleeved on the pivot shaft and having a first protruding arm portion and a second protruding arm portion, the first protruding arm portion being fixedly connected to the display screen; A second torsion spring is sleeved on the pivot shaft and has a third protruding arm and a fourth protruding arm, the third protruding arm being fixed to the display screen; and a switching button having a knob, a stop post, and a groove-shaped limiting structure. The knob is rotatably disposed on the cantilever to be operablely moved to a first position or a second position. The stop post protrudes from the center of the knob toward the pivot shaft, and the groove-shaped limiting structure protrudes from the knob toward the pivot shaft and is adjacent to one side of the stop post. When the knob is rotated to the first position, the stop post stops the second protruding arm, so that the first torsion spring provides torque to the display screen. When the knob is rotated to the second position, the stop post stops the second protruding arm, and the fourth protruding arm engages with the groove-shaped limiting structure, so that the first and second torsion springs together provide torque to the display screen.

5. The screen device as claimed in claim 4, wherein the first torsion spring and the second torsion spring are sleeved on the pivot shaft in a side-by-side manner.

6. The screen device as claimed in claim 4, wherein one of the first torsion spring and the second torsion spring is sleeved on the pivot shaft, and the other of the first torsion spring and the second torsion spring is sleeved on the first torsion spring and the second torsion spring.
