[0031] Please see Figure 1-4 This utility model provides a technical solution: a non-slip and stable dining table and chair, including a seat 1 and a backrest 2;

[0032] The seat 1 is equipped with four limiting devices;

[0033] The limiting device includes a mounting base 10, a rotating block 7, and a sliding column 3. One side of the upper end of the rotating block 7 is arc-shaped. One end of the sliding column 3 is fixedly connected to the lower surface of the rotating block 7. The upper outer wall of the rotating block 7 is rotatably connected to the lower interior of the mounting base 10. A push block groove 14 is provided on the upper outer wall of the rotating block 7. A push block 13 is slidably connected inside the push block groove 14. The right-angled edge of the upper end of the rotating block 7 contacts the lower inner wall of the mounting base 10. A rubber limiting block 15 is provided inside the push block groove 14. Both ends of the rubber limiting block 15 contact one end of the corresponding push block 13 and the inner wall of the push block groove 14, respectively. A first limiting block groove 17 is provided on the arc-shaped surface of the upper end of the rotating block 7. A limiting block 16 is slidably connected inside the first limiting block groove 17. The interior of the push block groove 14 communicates with the interior of the first limiting block groove 17. The end of the push block 13 near the limiting block 16 slides to the first limiting block. The inner wall of the block groove 17 is fixedly connected to the outer wall of the limiting block 16. The inner wall of the push block groove 14 is provided with two return springs 12. The two ends of the two return springs 12 are fixedly connected to the inner wall of the corresponding push block groove 14 and one end of the push block 13, respectively. The lower surface of the mounting base 10 is provided with a second limiting block groove 18. The end of the limiting block 16 near the second limiting block groove 18 slides to the outside of the rotating block 7 and contacts the inner wall of the second limiting block groove 18. The outer wall of the sliding column 3 is slidably connected with a sliding column sleeve 4. The upper outer wall of the sliding column sleeve 4 is threadedly connected with a first fixing bolt 5. The outer wall of the sliding column 3 is provided with multiple first fixing bolt grooves 6. The end of the first fixing bolt 5 near the first fixing bolt groove 6 extends threadedly to the inside of the sliding column sleeve 4 and is threadedly connected to the inside of the corresponding first fixing bolt groove 6. Four limiting devices are provided at the four corners of the lower end of the seat plate 1.

[0034] The lower surface of the seat plate 1 has four mounting slots 9, and each of the four mounting slots 9 has four second fixing bolt slots 8. The upper outer wall of the mounting seat 10 is slidably connected to the interior of the mounting slot 9. The lower surface of the four mounting seats 10 is threaded with four second fixing bolts 11. The end of each of the four second fixing bolts 11 near the second fixing bolt slot 8 extends into the interior of the mounting slot 9 and is threadedly connected to the interior of the corresponding second fixing bolt slot 8. The lower end of the backrest 2 is installed at the rear end of the seat plate 1 by bolts.

[0035] Furthermore, when using this device, pulling the sliding column 3 causes the rotating block 7 to rotate around the lower end of the mounting base 10, so that the upper end of the rotating block 7 contacts the inner wall of the lower end of the mounting base 10 at a right angle. Then, the force generated by the return spring 12 on the push block 13 causes the push block 13 to drive one end of the limiting block 16 into the interior of the second limiting block groove 18 to limit the rotating block 7. In this way, the seat plate 1 is supported by the four sliding column sleeves 4, and the anti-slip pad at the lower end of the sliding column sleeve 4 contacts the ground to increase the friction. When it is necessary to adjust the height of the seat plate 1, the first fixing bolt 5 is turned so that its other end is disengaged from the interior of the first fixing bolt groove 6. Then, the sliding column 3 is pulled. The sliding sleeve 4 can be pulled down from the sliding column 3. Then, the first fixing bolt 5 is turned to rotate so that its other end enters the corresponding first fixing bolt groove 6 to fix and limit the sliding sleeve 4. Then, when it is necessary to fold the sliding sleeve 4 and the sliding column 3, the handle of the rubber limiting block 15 is pulled to remove it from the inside of the push block groove 14. Then, the push block 13 is pushed down to move the limiting block 16 down, which at the same time causes the return spring 12 to retract. Then, the other end of the limiting block 16 is disengaged from the inside of the second limiting block groove 18 by moving the limiting block 16 down. Then, the sliding sleeve 4 is pulled to make the rotating block 7 flip around the lower end of the mounting base 10.

[0036] By pulling the handle on the rubber limit block 15 in the limiting device, the limit block 16 is removed from the inside of the push block groove 14. Then, the push block 13 is pushed down, which moves the limit block 16 down and at the same time, the return spring 12 is contracted. Then, the limit block 16 moves down so that the outer wall of its other end is disengaged from the inside of the second limit block groove 18. Then, the sliding column sleeve 4 is pulled to make the rotating block 7 rotate around the lower end of the mounting base 10. This improves the practicality and flexibility of the equipment and facilitates the handling and movement of the dining table and chairs.
