Pedestal structure for raised access floors

Abstract

A pedestal structure for raised access floors comprising: a supporting seat, a fixing seat and a socket set screw, wherein the supporting seat has on the top thereof a screw bolt which is connected on its bottom with a bottom seat, the bottom seat has a protruding portion having centrally a pivot hole, the bottom of the screw bolt is in a shape of “H” for the purpose of connecting into the pivot hole; while the fixing seat has a through hole for connecting by screwing with the screw bolt to raise the fixing seat; the screw bolt has on the top thereof a hexagonal adjusting hole for engaging therein a hexagonal wrench to adjust the height of the fixing seat relative to the supporting seat. The fixing seat is provided with a plurality of recessed portions for placing a raised access floor on and fixedly connecting with them. The socket set screw is connected by screwing into the through hole of the fixing seat; thereby the heights after screw connecting of the fixing seat and the supporting seat can be fixed. The structure is applicable to use for a network-line or pipeline laying out for raised access floors in a house, a building and a school etc.

1 . A pedestal structure for raised access floors comprising: 
 a supporting seat having on its top a screw bolt with a hexagonal adjusting hole on the top thereof, said screw bolt is connected on its bottom with a bottom seat; said bottom seat has a protruding portion having a central pivot hole, said bottom of said screw bolt is in a shape of “H” and is pivotally connected into said pivot hole;    a fixing seat provided for placing thereon and connected with a plurality of raised access floors and provided centrally with an interiorly threaded through hole, said fixing seat is connected by screwing with said screw bolt of said supporting seat; and    a socket set screw provided on said top of said screw bolt to be connected by screwing into said through hole of said fixing seat; said socket set screw has thereon a top-to-bottom extending hole of which the diameter is larger than that of said adjusting hole, in order to allow an adjusting tool to extend through said top-to-bottom extending hole to engage in said hexagonal adjusting hole for adjusting up and down displacement of said supporting seat relative to said fixing seat; by rotating said socket set screw, said screw bolt of said supporting seat is tightly abutted against said threaded through hole of said fixing seat.    
   
   
       2 . The pedestal structure for raised access floors as in  claim 1 , wherein said fixing seat is rectangular, and is provided centrally with said threaded through hole; a plurality of recessed portions are provided at four corners of said fixing seat and have thereon screw holes for placing and connecting of said raised access floors.  
   
   
       3 . The pedestal structure for raised access floors as in  claim 1 , wherein said bottom seat has on its bottom a pad to prevent direct contact of said bottom seat with the ground, and to reduce degree of oxidation of said bottom seat.  
   
   
       4 . The pedestal structure for raised access floors as in  claim 3  wherein said bottom seat has thereon a plurality of openings, said pad has thereon a plurality of protrusions, said protrusions are connected with said openings to make said pad to be firmly attached to said bottom of said bottom seat.  
   
   
       5 . The pedestal structure for raised access floors as in  claim 1 , wherein said through hole of said fixing seat is protruded downwards over said bottom of said fixing seat to increase length of adjusting of said screw bolt of said supporting seat relative to said through hole of said fixing seat to adapt to heights of the ground being more uneven.  
   
   
       6 . The pedestal structure for raised access floors as in  claim 1 , wherein said adjusting hole on said screw bolt and said top-to-bottom extending hole of said socket set screw are both hexagonal for engaging therein a hexagonal wrench for screwing tight or screwing loose.  
   
   
       7 . The pedestal structure for raised access floors as in  claim 1 , wherein said pivot hole has a slightly larger diameter than that of said screw bolt, in order that gaps are formed between said bottom of said screw bolt and said pivot hole; thus only said screw bolt rotates, said bottom seat is not moved, and said screw bolt is easier for adjusting to achieve a function of raising or lowering said pedestal.
