[0040] In the embodiment, the interior of each of the four lifting legs 3 is provided with a clamping groove 12, a lifting rod 13 fixedly arranged on the inner wall of each of the four clamping grooves 12, a sliding groove arranged in the interior of each of the four lifting rods 13, a spring plate 14 fixedly arranged on the inner wall of each of the four sliding grooves, and an inclined block 15 fixedly arranged on the top of each of the four spring plates 14.

[0041] In the embodiment, the stabilizing mechanism comprises four U-shaped blocks 6 rotatably arranged at both sides of the storage box 5, four mounting grooves arranged in the interior of the storage box 5, a reciprocating screw rod 18 rotatably arranged on the inner wall of each of the four mounting grooves, a translation block threadedly connected with the outer surface of each of the four reciprocating screw rods 18, a clamping plate fixedly arranged on one side of each of the eight translation blocks, and the eight translation blocks and the eight clamping plates 19 are slidably connected with the storage box 5.

[0042] In the embodiment, the outer surface of each of the four reciprocating screw rods 18 is fixedly provided with a bevel gear four 17, the four bevel gear fours 17 are engaged with a bevel gear three 16, the bevel gear three 16 is fixedly arranged on each of the four bevel gear threes 16, and the four second rocking handles are rotatably connected with the storage box 5.

[0043] In the embodiment, the adjusting mechanism comprises four fixed barrels 4 slidably arranged at the bottom of the four lifting legs 3, a threaded rod 26 rotatably arranged in the interior of each of the four fixed barrels 4, a moving block 27 threadedly connected with the outer surface of each of the four threaded rods 26, and the four moving blocks 27 are fixedly connected with the four lifting legs 3.

[0044] In this embodiment, bevel gear five 25 is fixedly installed on the outer surface of the four threaded rods 26, and the four bevel gears five 25 are meshed with bevel gear six 24. The four bevel gears six 24 are fixedly installed with rotating rods 23, and the four rotating rods 23 are rotatably connected to the four fixed barrels 4.

[0045] In this embodiment, a worm gear 22 is fixedly mounted on the outer surface of the four rotating rods 23, the four worm gears 22 are meshed with a worm 21, a third crank 20 is fixedly mounted on the four worms 21, and the four worms 21 and the four third cranks 20 are rotatably connected to the four fixed barrels 4.

[0046] In the present invention, when the chair is not in use, the armchair 2 is rotated by hand to fold the armchair 2 onto the seat surface 1. At the same time, the four lifting legs 3 and the fixed barrel 4 are removed and placed in the storage box 5. The four first cranks are rotated by hand to drive the four bevel gears 2 8 to rotate, the four bevel gears 2 8 drive the four bevel gears 1 28 to rotate, the four bevel gears 1 28 drive the four screws 9 to rotate, and the four screws 9 drive the four connecting blocks 10 to move downward during the rotation of the four connecting blocks 10, and the four pushing blocks 11 move downward. When the four pushing blocks 11 move downward, The four inclined blocks 15 can be pushed out, which will compress the four spring plates 14. When the four lifting legs 3 and the four fixed barrels 4 are assembled, the four spring plates 14 and the four inclined blocks 15 are pushed into the four grooves 7 by the four lifting rods 13. The disassembled lifting legs 3 and the fixed barrels 4 can be neatly stored in the storage box 5, avoiding the traditional chair from taking up a lot of space when not in use. The four lifting legs 3, the four fixed barrels 4, the backrest 2 and the seat 1 are placed in the storage box 5. When multiple storage boxes 5 are stacked together, the storage box 5 rotates the U block 6 to fit on another The second crank is then turned by hand to drive the bevel gear 3 16 to rotate, the bevel gear 3 16 drives the bevel gear 4 17 to rotate, the bevel gear 4 17 drives the reciprocating screw 18 to rotate, and the reciprocating screw 18 drives the two translation blocks to move closer to each other, thereby driving the two clamping plates 19 to move closer to each other, clamping the U block 6, and stabilizing the stacked storage boxes 5. This ensures that the storage boxes 5 will not easily collapse or slide when stacked, thereby greatly saving storage space. When the assembly is completed, the four lifting legs 3 and the four fixed barrels 4 are retracted. During adjustment, the four third crank handles 20 are rotated by hand, and the four third crank handles 20 drive the four worms 21 to rotate, the four worms 21 drive the four worm gears 22 to rotate, the four worm gears 22 drive the four rotating rods 23 to rotate, the four rotating rods 23 drive the four bevel gears 6 24 to rotate, the four bevel gears 6 24 drive the four bevel gears 5 25 to rotate, and the four bevel gears 5 25 drive the four threaded rods 26 to rotate. During the rotation of the four threaded rods 26, the four moving blocks 27 are driven to move upward, thereby driving the four lifting legs 3 to move upward, and the height of the chair legs can be adjusted.

[0047] Embodiment two

[0048] The difference between the present embodiment and embodiment one is that rubber blocks are arranged inside the storage box 5, so that the storage box 5 can be sealed to prevent the four lifting legs 3, the four fixed barrels 4, the armchair 2 and the seat surface 1 from being closely attached to the storage box 5.

[0049] The above merely describes a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, should be covered within the protection scope of the present application.
