Structure of a monitor support device with height adjusting function

Abstract

A monitor support includes a first supporting unit secured on a lowermost portion of a cabinet, a power source, and upright and horizontal supporting units joined to the first supporting unit, which cabinet has a pivotal cover for an upper opening thereof; the first supporting unit has an upright transmission screw passed through and threadedly engaged with the upright supporting unit such that the transmission screw will be turned, and height of the upright and the horizontal supporting units adjusted when the power source is activated; a monitor is held in place by the upright and the horizontal supporting units therefore the monitor can be held in the cabinet and protected from dust when not in use; the upright supporting unit has pushing rods at an upper end for pushing and opening the pivotal cover of the cabinet when the monitor is moved upwards outside the cabinet.

1 . A monitor support device with height-adjusting function, comprising 
 a secured supporting unit; the secured supporting unit having an upright transmission screw thereon;    a power source connected to the upright transmission screw so that the upright transmission screw will be turned when the power source is activated;    an upright supporting unit; the upright supporting unit being connected to the upright transmission screw of the secured supporting unit such that the upright supporting unit will be moved upwards when the power source is activated to turn the upright transmission screw in a first direction, and such that the upright supporting unit will be moved downwards when the power source is activated to turn the upright transmission screw in a second direction; and    a horizontal connecting unit for connection with a rear side of a monitor to hold the monitor in place; the horizontal connecting unit being joined to the upright supporting unit; the horizontal connecting unit being capable of being loosened from the upright supporting unit for relocation.    
   
   
       2 . The monitor support device as claimed in  claim 1 , wherein the secured supporting unit is secured on a bottom of a cabinet, which is used to protect a monitor held on the support device, and which has a pivotal cover on an opening of an upper end thereof, and the upright supporting unit has a plurality of pushing rods securely joined to an upper end thereof for pushing and opening the pivotal cover of the cabinet when the upright supporting unit is moved upwards and outside the cabinet.  
   
   
       3 . The monitor support device as claimed in  claim 1 , wherein the horizontal connecting unit includes a plurality of spaced -horizontal connecting bars; each of the horizontal connecting bars having a middle portion, left and right portions, a plurality of first connecting portions spaced apart on the left and the right portions thereof, and two second connecting portions between the left and the right portions thereof; the horizontal connecting bars being joined to a rear side of a monitor at the first connecting portions; the horizontal connecting bars being joined to the upright supporting unit with the second connecting portions being positioned around respective ones of upright rod parts of the upright supporting unit; screws being passed through the second connecting portions of the horizontal connecting bars and tightly pressed against the upright rod parts of the upright supporting unit.  
   
   
       4 . The monitor support device as claimed in  claim 3 , wherein the first connecting portions of the horizontal connecting bars are formed with holes thereon.  
   
   
       5 . The monitor support device as claimed in  claim 3 , wherein the second connecting portions of the horizontal connecting bars are hollow for allowing the upright rod parts of the upright supporting unit to be passed through.  
   
   
       6 . The monitor support device as claimed in  claim 1 , wherein the upright supporting unit includes: 
 a base; the base including a hollow part formed with internal threads; the base having two lead holes respectively formed on left and right ends thereof; the base having two bearings held in respective ones of the lead holes thereof; and    two upright rod parts; the upright rod parts being connected to two ends of the base respectively at lower ends thereof;    the secured supporting unit being passed through the bearings in the lead holes of the base of the upright supporting unit at two upright leading rods thereof; the upright transmission screw of the secured supporting unit being passed through and threadedly engaged with the hollow part of the base of the upright supporting unit.    
   
   
       7 . The monitor support device as claimed in  claim 6 , wherein the upright supporting unit has two propping parts joined to respective ones of the upright rod parts for holding a monitor thereon; the propping parts being capable of being loosened for relocation.  
   
   
       8 . The monitor support device as claimed in  claim 6 , wherein the base of the upright supporting unit has a hole, and the secured supporting unit has an upright position-limiting stick passed through the hole of the base of the upright supporting unit.  
   
   
       9 . The monitor support device as claimed in  claim 1 , wherein the secured supporting unit includes left and right upright leading rods, which are passed through the upright supporting unit.  
   
   
       10 . The monitor support device as claimed in  claim 9 , wherein the secured supporting unit has a covering plate secured a front thereof.
