[0035] The chair frame support pipe 20 is provided with a limiting block 6, when the lower end of the first rotating block 4 rotates forward around the first hinge point 41, the limiting block 6 can abut against the lower front edge of the first rotating block 4.

[0036] Further, the desk and chair are in the learning mode under normal circumstances, when it is needed to switch to the lunch break mode, the handle 31 is pressed to overcome the elastic force of the tension spring 5, the rear end of the second rotating block 3 is rotated downward around the second hinge point 32, the rotation of the first rotating block 4 is unlocked, the backboard 23 is rotated to be tilted, the first rotating block 4 finally abuts against one side of the limiting block 6, the backboard 23 is fixed, the deformation of the seat 2 is realized, for the desk 1, the desk board 13 is pulled, the desk board 13 is unfolded and fixed by the cooperation between the first telescopic pipe 121 and the second telescopic pipe 122, these designs not only simplify the operation steps of the user, but also reduce the time required for conversion, which is very suitable for the time management requirements in the campus environment.

[0037] Reference Figure 3 , Figure 4 The rear end of the second rotating block 3 is bent downward to form a first abutting part 33 for abutting against the lower edge of the first rotating block 4 and a second abutting part 34 for abutting against the front edge of the first rotating block 4. Specifically, under the abutment of the second rotating block 3 and the limiting column 42, the first rotating block 4 is in a fixed state, when the second rotating block 3 is rotated, the backboard 23 is rotated backward, which can easily drive the first rotating block 4 to rotate, when the first rotating block 4 abuts against the limiting block 6, the backboard 23 is tilted to the appropriate position, at this time, one side of the second rotating block 3 also abuts against the lower edge of the first rotating block 4, due to the weight of the backboard 23 and the backboard support 230, the tension of the tension spring 5 is not enough to drive the second rotating block 3 to rotate; when it is needed to restore the backboard 23, it is needed to press the handle 31 downward again for a short time, so that the second rotating block 3 does not interfere with the rotation of the first rotating block 4, when the backboard 23 is restored, finally the handle 31 is released, the second rotating block 3 is pulled by the tension spring 5 to abut and fix the first rotating block 4.

[0038] Reference Figure 5 , Figure 6The unfolding mechanism 12 comprises first telescopic pipes 121 hinged on both sides of the drawer cabinet 11, the first telescopic pipes 121 being hollow pipes with hollow cavities 1212, and second telescopic pipes 122 arranged on both sides of the desk board 13 and capable of being retracted into the hollow cavities 1212 of the first telescopic pipes 121.

[0039] The upper end of the first telescopic pipe 121 is provided with a support cavity 1210 offset from the hollow cavity 1212, and the cavity wall of the hollow cavity 1212 on the opposite side of the support cavity 1210 is provided with an elastic member 1211 for pushing the lower end of the second telescopic pipe 122 into the support cavity 1210.

[0040] Specifically, when unfolding the desk board 13, the second telescopic pipe 122 is gradually moved out of the hollow cavity 1212, and when the lower end of the second telescopic pipe 122 is completely separated from the hollow cavity 1212, the lower end of the second telescopic pipe 122 is slightly pushed into the support cavity 1210 under the action of the elastic member 1211, so that the desk board 13 is in a stable and fixed state; when it is necessary to restore the desk board 13, the lower end of the second telescopic pipe 122 needs to be pressed at the same time, so that the elastic member 1211 is compressed, and the second telescopic pipe 122 is retracted into the first telescopic pipe 121, preferably, the elastic member 1211 is a rubber member with variable volume, and the first telescopic pipe 121, the second telescopic pipe 122 and the desk board 13 are all made of light materials.

[0041] Preferably, the desk board 13 is provided with a support block 120 on both sides, and the second telescopic pipe 122 is hinged outside the support block 120.

[0042] The inside of the support block 120 is provided with a buckling convex part 1200, and the two side walls of the drawer cabinet 11 are provided with buckling grooves 110 for clamping the buckling convex part 1200, so as to increase the stability when the desk board 13 covers the upper surface of the drawer cabinet 11, and the buckling convex part 1200 and the buckling groove 110 are both made of hard plastic and have good deformation ability.

[0043] In summary, the utility model provides a lunch break desk and chair solution integrating multiple functions, which takes the humanized design concept as the core and fully considers the needs of users, aiming to create a healthier and more comfortable lunch break environment for primary and secondary school students.
