Referring to fig. 1 and 2, the present invention relates to a foldable desk and chair for a smart classroom, which comprises a desk 1; the desk 1 comprises four desk legs 101; the opposite surfaces of two adjacent desk legs 101 on the sitting and standing side of the student are rotatably connected with a bottom rod 2, and the bottom rod 2 can rotate between the horizontal state and the vertical state.

The length of the bottom rod 2 is less than or equal to that of the desk legs 101, so that the bottom rod 2 is positioned below the desk 1 after rotating to be in a vertical state. Meanwhile, the end of the bottom bar 2 is connected to the lower end of the table leg 101 so that the bottom bar 2 is supported on the ground when rotated to be horizontal.

One surface of each of the two bottom rods 2 is fixedly connected with a sliding rail 201; a supporting plate 202 is connected between the two sliding rails 201 in a sliding manner; the surface of the supporting plate 202 is fixedly connected with a seat air pressure rod 3; the upper end of the seat air pressure rod 3 is connected with a cushion plate 301; and the length of the cushion plate 301 is less than or equal to the distance between the opposite faces of two adjacent legs 101.

When the bottom rod 2 is in the horizontal state, the seat air pressure rod 3 is in the vertical state, so that the cushion plate 301 can be used for a person to sit and stand. The seat air pressure rod 3 can be adjusted in height according to the height of a person. The surface of the bottom rod 2 contacting the ground can be glued or screwed with a rubber pad to improve the buffering or vibration between the bottom rod 2 and the ground.

Meanwhile, the supporting plate 202 and the sliding rail 201 can slide, so that the distance between the cushion plate 301 and the desk 1 can be adjusted at will, and the desk is convenient for adapting to the sitting posture of people with different heights and physical constitutions.

When not in use, the bottom rod 2 can be rotated to enable the whole body to rotate into the lower part of the desk 1,

preferably, as shown in fig. 3, a limiting plate 203 is welded on the side of one of the bottom rods 2; the surface of the limit plate 203 is uniformly provided with limit teeth 204.

The lower surface of the supporting plate 202 is hinged with a pressing rod 4; one end of the pressing rod 4 is welded with a fixture block 401 clamped with the limiting teeth 204; a pedal 402 for pressing is welded to one end of the pressing rod 4.

The fixture block 401 is clamped with the limiting teeth 204, so that the position of the support plate 202 can be limited, the sitting position is kept, and when the adjustment is needed, the pedal 402 is pressed or stepped down to separate the fixture block 401 from the limiting teeth 204, so that the support plate 202 can move freely, and the position adjustment is realized.

Preferably, the hinge position of the support plate 202 and the pressing rod 4 is located at an end close to the pedal 402, so that the latch 401 is automatically pressed down by gravity and maintains the engagement state with the limit tooth 204.

In another preferred scheme, a torsional spring is sleeved on a hinged shaft of the supporting plate 202 and the pressing rod 4 which are hinged; the torsion spring generates torsion force to keep the fixture block 401 in a clamping state with the limit teeth 204, so that the stability after clamping is improved.

As another preferable scheme, one of the legs 101 connected to the bottom bar 2 is rotatably connected to a rotation shaft; the two ends of the rotating shaft penetrate through the table legs 101, and clamping plates 102 used for fixing the bottom rods 2 are welded or screwed at the two ends.

When the sill bar 2 rotates to a vertical state, the whole desk is stored under the desk 1, the clamping plates 102 are rotated, so that the two clamping plates 102 are limited when the two clamping plates 102 are respectively positioned at two sides of the sill bar 2, the sill bar 2 is prevented from rotating accidentally, and the whole desk is kept in a folded storage state.
