Coupling structure for tables

Abstract

The present subject matter is directed to a table coupling structure, comprising a first table and a second table coupled to each other, wherein a respective coupling groove is formed on the coupling side of each tabletop. A coupling member is inserted into the first coupling groove and the second coupling groove to couple the first tabletop and the second tabletop. When coupling the table structure, it is only necessary to insert the coupling member into the first coupling groove and the second coupling groove, thereby enabling the first tabletop and the second tabletop to be coupled together. The connection is firm and stable during use. For disassembly, it only needs to pull out the coupling member, making both coupling and disassembly of the coupling structure convenient. In addition, multiple tables can be connected together as needed, and different coupling methods can be flexibly combined.
