Shelf structure for loading computer equipment

Abstract

A shelf structure for loading computer equipment is composed of at least more than four vertical beams including a first, second, third, and fourth vertical beams; and at least more than one shelf constituted by an inner arm and an outer arm, wherein exteriors of the inner arm are fixed on the third and fourth vertical beams, and exteriors of the outer arm are fixed on the first and second vertical beams. The shelf is provided with a feature of quick adjustment of an assembly length, and a feature of higher strength for sustaining with a load, so as to be assembled on all kinds of vertical beams of different specifications and be able to be loaded with heavier and larger computer equipment.

1 . A shelf structure for loading computer equipment comprising at least more than four vertical beams including a first, second, third, and fourth vertical beams, whose one side surface is provided with a plurality of positioning holes respectively; at least more than one shelf composed of the following parts: an inner arm whose board surface is provided with at least more than one long groove, and whose side end is formed with a vertical board surface on which is installed with at least more than one protruded hook and at least more than one screw hole; an outer arm whose board surface is provided with more than one screw hole, and whose side end is formed with a vertical board surface on which is installed with protruded hooks and screw holes; bolts being transfixed into the long grooves and screwed into the screw holes of outer arm, enabling the inner arm and the outer arm to be screwed, fixed, and provided with a pre-determined assembly length; bolts being transfixed into the screw holes on the vertical board surface of the inner arm, and screwed into the positioning holes of the third and fourth vertical beams, with the hooks being locked into the positioning holes of the third and fourth vertical beams and the vertical board surface of the inner arm being fixed on the third and fourth vertical beams; bolts being transfixed into the screw holes on the vertical board surface of the outer arm, and screwed into the positioning holes of the first and second vertical beams, with the hooks being locked into the positioning holes of the first and second vertical beams and the vertical board surface of the outer arm being fixed on the first and second vertical beams.  
   
   
       2 . The shelf structure for loading computer equipment according to  claim 1 , wherein a surface of rims of screw hole of the outer arm is formed with a projection body and a surface at one side of long groove of the inner arm is formed with a concave part, and the projection body is fitted into the concave part.  
   
   
       3 . The shelf structure for loading computer equipment according to  claim 1 , wherein a board surface of inner arm is formed with a concave surface of a larger area and longer length which is provided with screw holes, the outer arm is provided with a long projection body having long grooves, the long projection body can be fitted into the concave surface, and bolts are screwed into the long grooves and the screw holes.  
   
   
       4 . The shelf structure for loading computer equipment according to  claim 1 , wherein a side edge of the outer arm is bended with a frame edge which is bended at about 90 degrees, whereas a side edge of inner arm is bended with a frame edge which is bended at about 90 degrees.  
   
   
       5 . The shelf structure for loading computer equipment according to  claim 1 , wherein the concave surface of the inner arm is extended forward to form a long concave part of a smaller area, and a front section of the long projection body on the outer arm is tightly fitted into the long concave part.
