Description

An automatic retractable table

Technical field:

The invention relates to the field of furniture articles, in particular to an automatic shrink table. the

Background technique:

At present, in restaurants, classrooms, and meeting rooms, there are not only many tables, but they are also neatly arranged and take up a lot of space. The foldable tables are all folded manually. When cleaning, they take up space and are not easy to clean. Fold them one by one. , not only very troublesome, but also low cleaning efficiency. the

Invention content:

The technical problem to be solved by the present invention is to overcome the deficiency of the background technology and provide an automatic retractable table so that the table can be automatically folded and docked at a designated position. In this way, when there are many tables, each table will not only automatically fold, but also dock at the designated position according to the previously programmed program, which not only saves time, but also has many functions. For example, in restaurants, meals can be delivered automatically to diners without waiters Run before and after. the

The present invention is realized through the following technical solutions: an automatic retractable table, including a table top, a bracket, a hinge hole 1, a connecting rod 1, a hinge hole 2, a connecting body 1, a table top 2, a connecting rod 2, a table leg 1, and a table leg 2.
