In this embodiment, the table body 1 is used as a base for designing a table and chair, and bears all mechanisms except the table body 1, and is the most important part of the folding table and chair; the connecting cylinder 13 is a cylindrical cylinder with the diameter of 150cm and the thickness of 4.5 cm. After the connecting cylinder 13 is established, "accommodating parts" are respectively established for the folding desk lamp 3, the folding reading frame 6, the rotating cabinet 4 and the rotating folding box 5, and the main instruction is stretching, cutting and shell drawing; the upper table plate 11 and the lower table plate 12 are basically the same in shape and are cylindrical sheets with the diameter of 150cm and the thickness of 3cm, three parts of the lower table plate 12 are cut off for mounting the pneumatic lifting chair 2, and the base and the lower table plate 12 are integrated when the lifting chair is completely folded.
In this embodiment, the pneumatic lifting chair 2 is a market conventional chair, and mainly comprises a base and a pneumatic lifting chairA press rod, a pneumatic rod connecting piece, a pneumatic rod lever, a pedal, a backrest and a chair surface. The chassis, the backrest and the seat surface are made of ABS (acrylonitrile-butadiene-styrene), the locking plate and the lever are made of stainless steel, and the air pressure rod is made of complex materials including ABS, rubber, aluminum alloy and the like. The pneumatic lifting chair 2 can change the height along with the extension and contraction of the pneumatic rod, the maximum height of the pneumatic lifting chair can be changed from 775.5mm to 954mm, the height of the chair seat can be changed from 395.5mm to 574mm, and the pedal design is particularly increased due to the fact that the height change is large and the chair can be used by children; the volume of the chair is 3031cm3Surface area of 8076663mm3The mass was 9.525 kg.
In this embodiment, as shown in fig. 5, the folding linkage of the folding reading rack 6 is a four-bar linkage, wherein the left and right links 610 and 611 are designed to be a broken line for easy folding and installation of the four-bar linkage, the angle between two straight lines in the broken line is 146.25 °, and the upper and lower links 612 and 613 are designed to be straight lines; the height difference between the two stable states of the four-bar linkage mechanism in the fully folded state and the fully extended state is 9.25cm, and the horizontal expansion and contraction amount is 35.87 cm.

In this embodiment, as shown in fig. 6 and 7, the rotating folding box 5 is designed into a multi-axis rotating type rotating folding box 5 to meet the desktop storage requirement; the rotating folding box 5 is mainly divided into three parts, which trisect a circle into three sectors as a main body of the rotating folding box 5, and the rotating part of each area is a sector. Taking the area of the main folding slot 53 as an example, it can be divided into three fan-shaped sub-areas, wherein the left rotating cabinet slot 54 and the main folding slot 53 adopt a nested design, and are nested into one after being folded, and the rotating shaft and the main folding slot 53 are the same as the left rotating shaft. The extreme end is a right-handed rotary cabinet groove 55 area which comprises an upper part and a lower part which are respectively two right-handed rotary cabinet grooves 55, the two parts share a right-handed rotary shaft and can be folded in the right area of the main folding groove 53. Between the left rotating bin slot 54 and the right rotating bin slot 55 is a storage area that takes full advantage of the remaining space, but does not have a rotating folding function. This shows that the rotating storage cassette is composed of 15 sub-storage cassettes in total.
