Description

Technical Field

[0001] The utility model relates to the technical field of table tennis tables, in particular to a table tennis table with a foldable and expandable combined structure. Background Technique

[0002] Table tennis, known as China's "national ball", is a world-famous ball sports project. Table tennis is very popular in China, with audiences ranging from the elderly to teenagers. In the process of playing table tennis, generally three pieces of equipment are required: table tennis rackets, table tennis balls, and table tennis tables. Among these three pieces of equipment, the table tennis table has the largest volume and weight.

[0003] After the existing table tennis tables are manufactured and leave the factory, their floor areas and tabletop sizes are generally fixed. They can only be placed in special places for people to exercise, and are not suitable for people to use for entertainment in work or living places. When they are idle, they occupy a large floor area, and their fixed sizes are not suitable for all application places either.

[0004] Therefore, it is necessary to design a table tennis table with a foldable and expandable combined structure. Content of the Utility Model

A second placement groove is provided on the upper side of the main frame, and a lid is rotatably arranged on the second placement groove. Four second lifting support legs are fixedly installed on the lower side of the main frame. Folding placement components are rotatably connected to both the left and right sides of the main frame, and an expandable folding component is detachably connected to the outside of the main frame and the folding placement components.

[0008] This technical scheme realizes the storage of the expandable folding component through the setting of the second placement groove, and realizes the adjustment of the table size through the setting of the folding placement component and the expandable folding component, so that the table can adapt to more occasions.

[0009] As a further scheme of the utility model: The folding placement component includes two first folding layers respectively rotatably connected to the left and right sides of the main frame. A second folding layer is rotatably connected to one side of the first folding layer. The folding directions of the first folding layer and the second folding layer are opposite. An installation frame is fixedly installed on the second folding layer. Two first lifting support legs are rotatably installed on the installation frame. First placement grooves are arranged on both the left and right sides of the installation frame. The expandable folding component is detachably connected to the outside of the first folding layer and the second folding layer.

[0010] This technical solution elaborates in detail the structure and composition of the folding and placing component.

[0011] As a further solution of the present utility model: The expansion and folding component includes an expansion and folding L-shaped plate and a first expansion and folding plate. The expansion and folding L-shaped plate and the first expansion and folding plate are detachably connected by a surrounding plate. The expansion and folding L-shaped plate is detachably connected to the outside of the second folding layer, and the first expansion and folding plate is detachably connected to the outside of the main frame, the first folding layer, and the second folding layer.

[0012] As a further solution of the present utility model: The expansion and folding component includes an expansion straight plate. One side of the expansion straight plate is detachably connected to the second folding layer, and the expansion straight plate and the main frame are detachably connected by a surrounding plate.

[0013] As a further solution of the present utility model: The expansion and folding component includes a second expansion and folding plate. One side of the second expansion and folding plate is detachably connected to the second folding layer, and the second expansion and folding plate and the main frame are detachably connected by a surrounding plate.

[0014] As a further solution of the present utility model: A cover plate is detachably arranged on the upper side of the two second folding layers after folding.

[0015] In summary, the beneficial effects of the present utility model are as follows: The storage of the expansion and folding component is realized by setting the second placement groove. The adjustment of the table size is realized by setting the folding and placing component and the expansion and folding component, so that the table can adapt to more occasions. At the same time, the equipment can occupy a smaller area when folded and can be used as a table by adding a cover plate. Description of the Drawings
