Description

Foldable multifunctional desk

Technical field

The present invention relates to a kind of desk, particularly Foldable multifunctional desk.

Background technology

The function ratio of current desk is on the market more single, substantially be all for classroom instruction, position once fixing carrying get up more inconvenient, the space taken is large, be not suitable for using in the residence of some narrow space or office space, and the people of different height can be very uncomfortable with the desk of same height, has a strong impact on the efficiency of listening to the teacher of student.And some course needs student to have certain activity space, and the carrying of desk is a tiring and troublesome thing, and result in a lot of courses cannot carry out within the limited time.In addition, present drawing often needs to carry out in fixing classroom, and this reduces dynamic role and the Initiative degree of student undoubtedly greatly.

Summary of the invention

For solving the deficiency that existing fixed desk takes up room, carries effort, cannot regulate, provide a kind of multifunctional desk, this desk can fold, and take up room little, convenient in carrying, flexible adjustment.

For achieving the above object, the present invention is by the following technical solutions:

Foldable multifunctional desk, comprises four table legs, tables, is connected below table leg by two hinged crossbars; Often prop up table leg comprise outer table leg and support table leg, chute is established in outer table leg, supporting table leg inserts in the chute of outer table leg, support on table leg and offer through hole, groove is offered in the inner side of outer table leg, screw is offered in the outside of outer table leg, a holding screw through the groove inside outer table leg, support table leg through hole, be threaded connection with the outside screw of outer table leg; Two of table and side support table leg by three-leaf type gemel connection.

Above-mentioned Foldable multifunctional desk, outer table leg is provided with the adjacent jockey of desk, and the insertion that this device comprises two the outer table legs being located at side hooks, and is located at the patchhole of opposite side two outer table legs.

Table leg carries out folding by crossbar, and table is turned down by three-leaf type hinge, and table leg carries out lift adjustment by screw stretching structure, and the desk after folding, adjacent jockey may be utilized to fix between two, conveniently carry in groups.

The utility model is easily carried, and desk height, table gradient can free adjustment.
