[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a reclining office chair with zero back-rubbing feeling, comprising a support seat 1, a lifting assembly 2 fixedly connected to the bottom end of the support seat 1, a plurality of universal wheels 3 fixedly connected to the bottom end of the lifting assembly 2, a chair back 4 rotatably connected to one side of the support seat 1, a moving mechanism is arranged at the top end of the support seat 1, the moving mechanism comprises a moving slot 5, two groups of the moving slots 5 are arranged, and the two groups of moving slots 5 are opened at the top end of the support seat 1, screws 6 are rotatably connected to the two ends of the moving slot 5, a moving block 7 is threadedly connected to the outer side of the screw 6, a cushion 8 is fixedly connected to the top end of the moving block 7, the lifting assembly 2 can adjust the height of the chair, and the universal wheels 3 can facilitate office workers to move the chair, and when the office workers need to lie down to rest, they can adjust the chair back 4 to lie flat, and at this time, if the back has a back-rubbing feeling, the position of the cushion 8 can be adjusted by rotating the rotating block 12, thereby adjusting the overall chair so that the back is in a comfortable position without being squeezed to form a back-rubbing feeling.

[0024] See also Figure 3 , Figure 4 and Figure 5Two groups of rotating wheels 9 are arranged on one side of the support seat 1, and the two groups of rotating wheels 9 pass through the support seat 1 and are fixedly connected to one end of the two groups of screw rods 6. A transmission belt 10 is arranged on the outside of the rotating wheel 9. The transmission belt 10 is sleeved on the outside of the two groups of rotating wheels 9. A protective shell 11 is arranged on the outside of the transmission belt 10. The protective shell 11 is fixedly connected to the support seat 1. A rotating block 12 is arranged on one end of the protective shell 11. The rotating block 12 passes through the protective shell 11 and is fixedly connected to the outside of one group of rotating wheels 9. The moving block 7 is completely inside the moving groove 5. The size of the moving block 7 is adapted to the size of the moving groove 5. Through the rotation of the rotating block 12 The movable block 12 drives the rotating wheel 9 connected thereto to rotate. Since the two groups of rotating wheels 9 rotate with the two groups of screw rods 6, and a transmission belt 10 is sleeved on the outside of the two groups of rotating wheels 9, the rotation of the rotating block 12 will simultaneously drive the two groups of screw rods 6 to rotate together. Since the size of the movable block 7 matches the size of the movable groove 5, the rotation of the screw rod 6 will cause the outer side of the movable block 7 and the inner side of the movable groove 5 to squeeze each other, making it impossible for the movable block 7 to rotate together with the screw rod 6. In this way, the movable block 7 can move on the screw rod 6, thereby driving the seat cushion 8 to move. The protective shell 11 can prevent the transmission belt 10 from falling off the rotating wheel 9 when it rotates.

[0025] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 A through slot 13 is provided on one side of the movable slot 5, and a connecting block 14 is arranged inside the through slot 13.

A clamping slot 16 is provided at one end of the armrest, and a protective pad 17 is clamped inside the clamping slot 16. A backrest pad 18 is arranged on the side of the chair back 4 close to the seat cushion 8. The material of the backrest pad 18 is mesh cloth. The armrest is fixed to the movable block 7 through the connecting block 14, so when the seat cushion 8 is moved, the armrest and the seat cushion 8 are moved together at the same time, so that the hand can be placed on the armrest regardless of the position of the seat cushion 8. The protective pad 17 can be fixed by clamping in the clamping slot 16 and the static friction generated by the clamping. The protective pad 17 can be used to protect the arm placed on the armrest from being scratched, and the protective pad 17 can be disassembled and cleaned at any time. The backrest pad 18 made of mesh cloth can make the back of the office worker not have an overly hard texture when leaning against the chair back 4, thereby increasing its comfort.

[0026] Working principle: the lifting assembly 2 can adjust the height of the chair, and the universal wheel 3 can facilitate the office staff to move the chair. When the office staff needs to lie down to rest, they can adjust the chair back 4 to lie flat. At this time, if the back feels rubbed, the rotation of the rotating block 12 can drive the rotating wheel 9 connected to it to rotate. Since the two groups of rotating wheels 9 rotate with the two groups of screw rods 6, and the outer sides of the two groups of rotating wheels 9 are provided with a transmission belt 10, the rotation of the rotating block 12 will simultaneously drive the two groups of screw rods 6 to rotate together and drive the moving block 7 to move, thereby adjusting the position of the seat cushion 8, thereby adjusting the overall chair, so that the back is in a comfortable position without The protective shell 11 can prevent the transmission belt 10 from falling off the rotating wheel 9 when rotating. The armrest is fixed to the moving block 7 through the connecting block 14. Therefore, when the seat cushion 8 is moved, the armrest and the seat cushion 8 are moved together at the same time, so that the hand can be placed on the armrest regardless of the position of the seat cushion 8. The protective pad 17 can be fixed by the clamping connection with the clamping slot 16 and the static friction generated by the clamping connection. The protective pad 17 can be used to protect the arm placed on the armrest from being scratched. The backrest pad 18 made of mesh material can make the back of the office worker not have an overly hard texture when leaning on the chair back 4, thereby increasing its comfort.
