A desk plate support structure comprises a desk plate 1 and a support frame. The support frame includes first landing leg 2 and second landing leg 3, and first landing leg 2 one end rotates with table 1 to be connected, and first landing leg 2 other end rotates with second landing leg 3 to be connected, and the axis of rotation of first landing leg 2 and table 1 is perpendicular table 1, and the axis of rotation of first landing leg 2 and second landing leg 3 and table 1 parallel arrangement.

The table 1 includes an upper cover 11 and a lower cover 12. An opening 121 is formed in the middle position of the lower cover body 12, the edge of the opening 121 extends towards the upper cover body 11 to form a first positioning portion 122, and the first positioning portion 122 is of an irregular annular structure. The lower end surface of the upper cover 11 forms a second positioning portion 111, and the second positioning portion 111 is also of an irregular annular structure. When the upper cover 11 and the lower cover 12 are connected by bolts, the outer wall of the first positioning portion 122 abuts against the inner wall of the second positioning portion 111, and the height of the first positioning portion 122 is smaller than the height of the second positioning portion 111. The first positioning part 122, the second positioning part 111, the side wall of the upper cover body 11, the top wall of the upper cover body 11, the side wall of the lower cover body 12 and the bottom wall of the lower cover body 12 form an annular cavity structure; the inner wall of the side wall of the upper cover 11 abuts the outer wall of the side wall of the lower cover 12.

The first leg 2 is rotatably connected to the lower cover 12 by a first connection assembly. The first connection assembly includes a connection end cap 41, a fastening bolt 42, a spacer 43. The lower cover 12 is recessed downward to form a mounting portion 123, and a connecting hole is formed in the center of the mounting portion 123. The upper end of the end cap 41 is fixed with a positioning column 441, and the positioning column 441 passes through the lower cap body 12 to extend into the cavity. The top of the first leg 2 forms a boss 21, and a fastening bolt 42 is screwed through the washer 43, the end cap 41, the connection hole, and the boss 21 of the first leg 2. The fastening bolts 42 are provided in two, so that the fastening bolts 42 can be effectively prevented from loosening. The end cap 41 is positioned above the mounting portion 123 and abuts against the upper end surface of the protruding portion 21, and the end cap 41 is disposed at a distance from the mounting portion 123. The top of the first supporting leg 2 is positioned on the outer ring of the convex part 21 to form a mounting groove 22, a supporting pad 44 is placed in the mounting groove 22, and the lower cover 12 is abutted against the supporting pad 44.

The end cover 41 lower extreme is fixed with stopper 442, and stopper 442 is the arc piece, and limit groove 23 has been seted up to first landing leg 2 top, and limit groove 23 is the arc groove, and the radian of limit groove 23 is greater than the radian of stopper 442, and stopper 442 rotates along with lower lid 12 in limit groove 23.

The second supporting leg 3 is rotatably connected with the first supporting leg 2 through a second connecting component; the second leg 3 comprises a locking bolt 51 and a connecting piece 52; the locking bolt 51 is connected to the second leg 3 through a connecting piece 52. The abutting surface of the second supporting leg 3 and the first supporting leg 2 is provided with a rubber sheet 53, and the locking bolt 51 is not easy to loosen due to the arrangement of the rubber sheet 53. The first supporting leg 2 is fixedly provided with a limiting strip 24, and the limiting strip 24 is of an arc-shaped structure and is provided with two limiting strips. The second leg 3 is provided with a guide groove 31 corresponding to the limit bar 24. The limiting strip 24 penetrates through the rubber sheet 53 and stretches into the guide groove 31, the guide groove 31 is also an arc-shaped groove, and the radian is larger than that of the limiting strip 24, so that the rotation angle of the first supporting leg 2 relative to the second supporting leg 3 is limited.

So that the second leg 3 is fastened to the chair by means of bolts when this is done. When the desk needs to be stored, the first supporting leg 2 rotates 90 degrees so that the desk board 1 rotates from a horizontal state to a vertical state. When a person needs to come out of the chair, the table 1 can be directly rotated, and the lower cover 12 can be separated from the supporting pad 44 by lifting the table 1, so that the rotation is convenient. The bottom of the end cover 41 is provided with an annular strip 411, and the cross section of the annular strip 411 is arc-shaped and convex, so that even if the lower cover body 12 is lifted up, the lower cover body is in line contact with the annular strip 411, and the friction resistance is small.
