technical field

The invention relates to a novel table and chair module that can be accommodated in a floor and seamlessly bonded to the floor.

Background technique

For students, the classroom is an important place that they must come into contact with almost every day. However, there are generally the following unsatisfactory places in today's existing classrooms that need to be improved urgently.

1. Existing classrooms come in different sizes, and each size can accommodate different numbers of students. However, since the desks and chairs in each classroom are matched and fixed, smaller classrooms are often too crowded or even insufficient. And those very large classrooms often have a lot of surplus and waste of space. At the same time, a certain number of tables and chairs limits the function of the classroom and reduces the space utilization rate.

2. The existing tables and chairs are fixed, so the size of the desktop and chair surface is also greatly restricted, and cannot be changed according to the actual situation and needs.

3. The existing folding tables and chairs cannot be folded and directly fit the floor seamlessly and be stored in the floor.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings and deficiencies of the above-mentioned prior art, and to provide a matching table and chair module used in classrooms and other places. After the module is folded, it can be completely stored in the floor. ) to achieve seamless fit with the ground, and at the same time, the adjustment of the height of the table and chair can be realized conveniently by using the adjustment of the card slot. In addition, tables and chairs can be partially or completely stored on the ground to achieve flexible space adjustment and improve space utilization.

Since the desks and chairs used in the existing classrooms and other places are all matched and fixed, and the existing folding desks and chairs cannot be stored in the floor and are seamlessly attached to the floor, so the patent of the present invention is mainly to realize that the desks and chairs can be folded after storage. It is completely attached to the ground to achieve the purpose of saving and using space flexibly.

To achieve the above object, the present invention adopts the following technical solutions:
