Shelf adjusting and fixing structure of a rack

Abstract

The present invention discloses a shelf adjusting and fixing structure of a rack, and the rack comprises a transversal rod disposed on the back side of two vertical rods, one being on the left side and the other one on the right side of the rack, and the transversal rod can be adjusted vertically along the vertical rod and fixed onto the vertical rod, and the transversal rod has one end coupled to a connecting board and the other end pivotally coupled to a shelf disposed on the front side of the two vertical rods. The present invention can achieve the objective of adjusting the height of the shelf by moving the transversal rod vertically with respect to the position of the vertical rods.

1 . A shelf adjusting and fixing structure of a rack, having a shelf disposed at the front side of two vertical rods one on the left side and the other one on the right side of said rack, and said shelf adjusting and fixing structure of said rack comprising: 
 a transversal rod, being disposed across said two vertical rods by a vertical adjusting and fixing measure for fixing a different plane of said shelf; and    two connecting boards, having both ends individually coupled to said transversal rod and said shelf by a pivotal measure.    
     
     
         2 . The shelf adjusting and fixing structure of a rack of  claim 1 , wherein said vertical adjusting and fixing measure for said transversal rod comprises a plurality of through holes disposed on said two vertical rods and on said different plane of said shelf; and at least one fixed hole passing along a radial direction through a rod body disposed proximate to both ends of said transversal rod; such that a fixing device passes through said fixed hole to secure one set of said through holes of said two vertical rods to fix said transversal rod across said two vertical rods on said different plane of said shelf.  
     
     
         3 . The shelf adjusting and fixing structure of a rack of  claim 2 , wherein said through hole of said two vertical rods at its periphery comprises a recess and part of the surface of said vertical rod is embedded into said recess when said transversal rod is fixed across said two vertical rods.  
     
     
         4 . The shelf adjusting and fixing structure of a rack of  claim 2 , wherein said fixing device for fixing said transversal rod onto said two vertical rods is rotated manually.  
     
     
         5 . The shelf adjusting and fixing structure of a rack of  claim 2 , wherein said connecting board having one end coupled to said shelf and the other end coupled to said transversal rod, and the height of said end coupled to said shelf is lower than said other end coupled to said transversal rod such that the corresponding edges of said shelf and said vertical rods lean against said vertical rods.  
     
     
         6 . A shelf adjusting and fixing structure of a rack, having a shelf disposed at the front side of two vertical rods one on the left side and the other one on the right side of said rack, and said shelf adjusting and fixing structure of said rack comprising: 
 a plurality of through holes disposed on the back side of said two vertical rods and the wall around said through hole having a slight recess;    a transversal rod, having at least one fixed hole passing along a radial direction through a rod body disposed proximate to both ends of said rod body, such that a fixing device being rotated manually and secured into a set of said through holes of said two vertical rods, and fixing said transversal rod across the back side of said two vertical rods and part of the surface of said transversal rod being embedded into said recess;    two connecting boards, having both ends coupled individually to an end of said transversal rod and an end of said shelf by a pivotal measure.    
     
     
         7 . The shelf adjusting and fixing structure of a rack of  claim 6 , wherein said connecting board having one end coupled to said shelf and the other end coupled to said transversal rod, and the height of said end coupled to said shelf is lower than said other end coupled to said transversal rod such that the corresponding edges of said shelf and said vertical rods lean against said vertical rods.
