Assembled table carriage

Abstract

The present invention provides an assembled table carriage, including a vertical support and at least a grounding support. The grounding support is exposed transversely at the periphery of the vertical support, where a mating end and a protruding end are formed. An axial groove and axial rib are mated between the periphery of vertical support and the mating end of the grounding support, thus enabling the grounding support to be slid axially via the mated axial groove and axial rib and also positioned via a spacer. The shelving unit can be embedded into the vertical support for axial sliding, allowing to adjust the height of table with greater convenience and applicability.

1 . An assembled table carriage, comprising:
 a vertical support; and   a grounding support, being exposed transversely at a periphery of the vertical support, and forming a mating end and a protruding end,   wherein an axial groove and axial rib mated between the periphery of vertical support and the mating end of the grounding support, said grounding support being slid axially via the mated axial groove and axial rib and positioned via a spacer.   
     
     
         2 . The table carriage defined in  claim 1 , wherein the axial groove and axial rib are of dovetail profile. 
     
     
         3 . The table carriage defined in  claim 1 , wherein said spacer is comprised of a clamping wedge and a bolt, said mating end of the grounding support being provided with a chamber for assembly of the clamping wedge, said clamping wedge having an oblique surface arranged between the clamping wedge and the chamber, wherein, when the clamping wedge is screwed by the bolt, the oblique surface of the chamber is supported by the oblique surface of the clamping wedge, allowing the mating end of the grounding support and the vertical support to be positioned securely, an embedding portion being arranged between the clamping wedge and the periphery of the vertical support. 
     
     
         4 . The table carriage defined in  claim 1 , wherein the scale is set on the periphery of the vertical support. 
     
     
         5 . The table carriage defined in  claim 1 , wherein several grounding supports can be separately assembled around the vertical support in a radiative state. 
     
     
         6 . The table carriage defined in  claim 1 , wherein the grounding supports are individually prefabricated. 
     
     
         7 . The table carriage defined in  claim 1 , wherein the vertical support is a hollow extruded tube. 
     
     
         8 . The table carriage defined in  claim 1 , wherein the vertical support is of round, square and polygonal profiles.
