Description

Technical Field

[0001] The utility model relates to the field of sports goods, in particular to a guide rail lifting and folding table tennis table. Background Art

[0002] Table tennis is my country's "national sport" and a popular ball sport in the world. Table tennis tables are the carrier equipment for table tennis, and there are many types of them. Traditional ones in schools, parks, communities and other places are fixed and do not need to be disassembled. However, table tennis tables are now commonly found in homes, and families generally purchase table tennis tables through online platforms. Therefore, merchants need to put forward higher requirements for the transportation compression space of the products, so as to save transportation costs and packaging costs. Traditional table tennis tables have handle-type folding methods, connecting rod-type folding methods, etc., but because the tabletop needs to be stood up or unfolded when folded, the tabletop has a certain amount of deadweight, and it is unstable and easy to get stuck when unfolded and folded, and the flatness after unfolding is also biased.
