Abstract

An assembly structure for ping-pong table top is provided, including a first table plate, a second table plate, at least a fixing unit and at least a support unit. The fixing unit includes a first matching element, a second matching element and a coupling element. The first and second matching elements are fastened respectively to bottom of the first and second table plates. When coupling element coupled to the first and second matching elements, two table plates cannot be separated. The support unit includes a fixing element and a collaborating element. The collaborating element has an arch-door shape so that bottom of collaborating element can match fixing element. When assembled, an axis receiving hole is formed between fixing element and collaborating element so that fixing unit can splice two table plates together. Table legs are assembled to support unit. As such, the user can easily assemble the ping-pong table.

         3 . The assembly structure as claimed in  claim 2 , wherein when said first latch and said second latch are also aligned side-by-side, said first latch and said second latch form a body having a T-shaped cross-section, cross-section of said latch slot is also T-shaped. 
     
     
         4 . The assembly structure as claimed in  claim 1 , wherein side walls of said first matching element and said second matching element, which facing each other, comprise a first fit wall and a second fit wall respectively; said first fit wall and said second fit wall are non-planar and have matching shape; when said first matching element uses said first fit wall to fit tightly with said second fit wall of said second matching element, said first matching element and said second matching element cannot move separately along the direction of surface of said first table plate and said second table plate where said first table plate and said second table plate are spliced side-by-side together. 
     
     
         5 . The assembly structure as claimed in  claim 4 , wherein said first fit wall and said second fit wall comprises at least one of the following: a plurality of slant surfaces in vertical orientation, a plurality of concave surfaces, and a plurality of convex surfaces. 
     
     
         6 . The assembly structure as claimed in  claim 1 , wherein said fixing element is disposed with at least two parallel latch racks, said collaborating element has a shape of an arch door, with bottom forming at least two concave latch slots; when said latch racks slide into said latch slots, said coupled collaborating element cannot be disengaged from said fixing element along a direction perpendicular to surface of table plate. 
     
     
         7 . The assembly structure as claimed in  claim 6 , wherein vertical cross-section of said latch rack has a convex T-shape and vertical cross-section of said latch slot has a concave T shape so that said latch slot of said collaborating element can only be assembled to said latch rack of said fixing element in a direction parallel to the surface of table plate. 
     
     
         8 . The assembly structure as claimed in  claim 1 , wherein center surface of said fixing element forms an arc surface, located between two said latch racks; inner wall of arch door shape of said collaborating element is also an arc surface; when said collaborating element is assembled to said fixing element, said arc surface of said fixing element and said inner wall of said collaborating element form a space to receive an axis for rotation. 
     
     
         9 . The assembly structure as claimed in  claim 1 , wherein when said support unit comprises two fixing elements and a collaborating element, two said fixing elements are fixed to surfaces of said first table plate and said second table plate respectively, when said collaborating element is spliced with said two fixing elements, an axis receiving hole is formed.
