Slot board structure for a shelf

Abstract

A slot board structure for a shelf comprises a plurality of slot boards, two side plates, and a plurality of hanging arms. The slot boards are stacked one another from top to bottom. The two side plates are respectively connected with a left and right side of each slot board. Each side plate has a rear shielding plate portion, a connection plate portion, a front shielding plate portion, and a plurality of inverted L-shaped hook portions. Two side plates are respectively connected with the left and the right sides of each slot board so that one part of each L-shaped side plate may shield the front side of each slot board to prevent the connection among the slot boards from exposing. The quantity of the slot boards is different so as to adjust the volume of the slot board structure and further adapt to the shelf having different sizes.

What is claimed is: 
     
         1 . A slot board structure for a shelf, at least comprising a plurality of slot boards, two side plates, and a plurality of hanging arms, the slot boards are stacked one another from top to bottom, an L-shaped slot is defined between two adjacent slot boards, the two side plates are respectively connected with a left side and a right side of each slot board, wherein:
 each side plate has a rear shielding plate portion, a connection plate portion, a front shielding plate portion, and a plurality of inverted L-shaped hook portions, the rear shielding plate portion is connected with a rear side of each slot board, the connection plate portion is forwardly extended from one side of the rear shielding plate portion adjacent to the slot boards, a center of the front shielding plate portion in length direction is connected with one side of the connection plate portion opposite to the rear shielding plate portion so that one part of the front shielding plate portion shields a front side of each slot board and a rear side surface of the other part thereof has the inverted L-shaped hook portions, the inverted L-shaped hook portions are backwardly extended from the rear side surface of the front shielding plate portion and spaced apart one another from top to bottom, and the front shielding plate portion is in parallel to the rear shielding plate portion.   
     
     
         2 . The slot board structure as claimed in  claim 1 , wherein each slot board includes a first elongated plate body, a second elongated plate body, a third elongated plate body, a fourth elongated plate body, a fifth elongated plate body, a sixth elongated plate body, and a seventh elongated plate body, a length direction of the first elongated plate body is arranged horizontally and a width direction thereof is arranged vertically, a length direction of the second elongated plate body is arranged horizontally, one side of the second elongated plate body in the length direction is connected with a lower side of the first elongated plate body, the second elongated plate body is forwardly extended from the lower side of the first elongated plate body, a length direction of the third elongated plate body is arranged horizontally, one side of the third elongated plate body in the length direction is connected with a front side of the second elongated plate body, the third elongated plate body is downwardly extended from the front side of the second elongated plate body, a length direction of the fourth elongated plate body is arranged horizontally, one side of the fourth elongated plate body in the length direction is connected with a lower side of the third elongated plate body, the fourth elongated plate body is backwardly extended from the lower side of the third elongated plate body, a length direction of the fifth elongated plate body is arranged horizontally, one side of the fifth elongated plate body in the length direction is connected with a rear side of the fourth elongated plate body, the fifth elongated plate body is upwardly extended from the rear side of the fourth elongated plate body, a length direction of the sixth elongated plate body is arranged horizontally, one side of the sixth elongated plate body in the length direction is connected with an upper side of the fifth elongated plate body, the sixth elongated plate body is backwardly extended from the upper side of the fifth elongated plate body, and the seventh elongated plate body is downwardly extended from one side of the sixth elongated plate body opposite to the fifth elongated plate body;
 for the two adjacent slot boards, a rear side of the sixth elongated plate body of the upper slot board is connected with an upper side of the first elongated plate body of the lower slot board so that a first space and a second space are formed, the first space is defined between the fourth elongated plate body of the upper slot board and second elongated plate body of the lower slot board, the second space is defined between the fifth elongated plate body of the upper slot board and the first elongated plate body of the lower slot board, the first space and the second space are fluidly communicated with each other to form the L-shaped slot, and the seventh elongated plate body of the upper slot board is abutted against a rear side surface of the first elongated plate body of the lower slot board. 
 
     
     
         3 . The slot board structure as claimed in  claim 2 , further comprising at least one fixing plate, a front surface of the at least one fixing plate is connected with the rear side of the first elongated plate body of each slot board. 
     
     
         4 . The slot board structure as claimed in  claim 1 , wherein each hanging arm has an embedding portion and an arm portion, the embedding portion includes an L-shaped section and a flat-plate section, one end of the L-shaped section is connected with the flat-plate section to form an N-shaped structure, the L-shaped section is slidably embedded in one of the L-shaped slots of the slot boards, the flat-plate section is exposed to the corresponding L-shaped slot, the arm portion is extended from the flat-plate section to a direction which is distant from the slot boards.
