As shown in figure 1, the afternoon nap desk and chair comprises a desk 1 and a chair 2. The table 1 comprises table support feet 11 and a table top 12. The bottom of the table panel 12 is provided with two parallel table supporting legs 11, a cross beam 13 is arranged between the two table supporting legs 11, a leg placing plate 14 is rotatably arranged on the cross beam 13, and the axis of the rotation direction of the leg placing plate 14 is parallel to the length direction of the cross beam 13. The leg rest plate 14 is further provided with a first rotation limiting mechanism 3, and the first rotation limiting mechanism 3 is used for limiting the rotation of the leg rest plate 14. The chair 2 comprises chair support legs 21, a chair panel 22 and a backrest 23. The bottom of the chair panel 22 is provided with chair supporting legs 21, and the rear part of the chair supporting legs 21 is rotatably provided with a backrest 23, so that the angle between the chair panel 22 and the backrest 23 can be adjusted by rotating the backrest 23. A second rotation limiting mechanism 4 is further provided between the chair support leg 21 and the backrest 23, and the second rotation limiting mechanism 4 is used for limiting the rotation of the backrest 23.

As shown in fig. 2, the first rotation limiting mechanism 3 includes a rotating plate 31 and a locking screw 32. One end of the rotating plate 31 is rotatably provided on the cross member 13 and is coaxially provided with the cross member 13. The bottom of the leg rest plate 14 is fixedly connected with the top of the rotating plate 31. A locking screw 32 is screwed with the rotation plate 31 from the top surface of the leg rest plate 14 downward through the leg rest plate 14, and the bottom of the locking screw 32 abuts against the cross member 13. When the first rotation limiting mechanism 3 is used, the locking screw 32 is rotated to be away from the cross beam 13, and after the position of the leg rest plate 14 is adjusted, the locking screw 32 is locked again, so that the leg rest plate 14 is fixed on the cross beam 13 and cannot turn over.

As shown in fig. 3, the second rotation limiting mechanism 4 includes a ratchet 41, a ratchet claw 42, a handle 43, and a spring 44. Ratchet wheel 41 is fixed on the side of the back end of chair support foot 21, the lower end of ratchet clamping jaw 42 is matched with ratchet wheel 41, one end of spring 44 is fixed on the lower part of backrest 23, the other end is connected with the lower end of ratchet clamping jaw 42, so that ratchet clamping jaw 42 is pressed on ratchet wheel 41. The upper end of ratchet claw 42 is rotatably disposed on the side of the lower portion of backrest 23, and handle 43 is disposed at the upper end of ratchet claw 42. When the second rotation limiting mechanism 4 is used, the handle 43 is rotated clockwise, the handle 43 drives the lower end of the ratchet clamping jaw 42 to move upwards, the ratchet clamping jaw 42 leaves the ratchet 41, the spring 44 is compressed at the same time, the backrest 23 can rotate relative to the chair supporting foot 21, after the angle of the backrest 23 is adjusted, the handle 43 is loosened, and under the action of the spring 44, the ratchet clamping jaw 42 is pressed on the ratchet 41 to prevent the backrest 23 from moving.
