[0018] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0019] Please refer to Figure 1 、 Figure 2and Figure 3 ,in Figure 1 This is a structural schematic diagram of a preferred embodiment of a cushioning and decompression office chair provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the massage block installation structure is shown; Figure 3 for Figure 1 The schematic diagram of the second gear installation structure shown is a buffering and decompression office chair, comprising: a backrest 1, a first gear 2 is equidistantly installed on one side of the inner side of the backrest 1, and the number of the first gears 2 is multiple, and the multiple first gears 2 are meshed with each other, and a massage block 3 is fixedly installed on one side of the outer side of the multiple first gears 2, and a third gear 6 is connected to the keyway on the other side of the outer side of one of the first gears 2, and the outer side of the third gear 6 is meshed with the second gear 5, and the keyway at the center point of the second gear 5 is connected to the motor 4, and the motor 4 is fixedly installed on the backrest 1, and a cushion is fixedly installed inside the backrest 1 and outside the multiple massage blocks 3. 7. Long-term office work will cause fatigue to the staff. During the lunch break, the office chair backboard 1 is placed flat and the staff lies on it. The motor 4 drives the second gear 5 to rotate, and the rotation of the second gear 5 drives the third gear 6 to rotate. The rotation of the third gear 6 drives one of the first gears 2 to rotate. Since the multiple first gears 2 are engaged with each other, the multiple first gears 2 rotate together, and the multiple first gears 2 drive the multiple massage blocks 3 to rotate, thereby effectively massaging and relaxing the staff's back, having the function of buffering and decompression, improving the quality of the lunch break, and thus improving the efficiency of the afternoon office.

[0020] The bottom of the backrest 1 is rotatably mounted with a mounting seat 8 through a pin shaft, an outer side of the mounting seat 8 is fixedly mounted with a base plate 9, a seat cushion 10 is fixedly mounted on the top of the base plate 9, an adjusting rod 11 is fixedly mounted at the bottom center point of the base plate 9 through a screw, a bracket 12 is fixedly mounted at the bottom end of the adjusting rod 11, and a rotatable universal wheel 13 is fixedly mounted in an equidistant ring at the bottom of the bracket 12, and there are multiple universal wheels 13. The multiple universal wheels 13 make it convenient to move the office chair, which is convenient for the staff to use.

[0021] The first connecting rods 14 are rotatably installed on both sides of the outside of the base plate 9, and there are two first connecting rods 14. One end of the two first connecting rods 14 is rotatably installed with the second connecting rods 15, and one end of the two second connecting rods 15 are rotatably installed on both sides of the outside of the back plate 1. A first knob 16 is provided between the first connecting rod 14 and the second connecting rod 15. The first connecting rod 14 is fixed to the second connecting rod 15 by locking the first knob 16. When the back plate 1 needs to be laid flat, the two first knobs 16 are loosened. At this time, the first connecting rod 14 and the second connecting rod 15 can be rotated, and the angle of the back plate 1 can be adjusted. After adjusting to the appropriate angle, the first knob 16 is locked. The structure is simple and easy to use.

[0022] A headrest 17 is slidably installed on the top of the backrest 1, and second knobs 18 are threadedly connected to the outer sides of the backrest 1 and above the second connecting rod 15. The headrest 17 is fixed to the backrest 1 by locking the second knobs 18. The headrest 17 is used to support the head, and the heights of different staff members are different, so the position of the headrest 17 needs to be adjusted. When adjusting, first loosen the two second knobs 18. At this time, the headrest 17 can be adjusted. After adjusting to the appropriate position, lock the second knob 18, which improves practicality.

[0023] The working principle of the cushioning and decompression office chair provided by the utility model is as follows:

[0024] Step 1: Long-term office work will cause fatigue to the staff. During the lunch break, the office chair backrest 1 is placed flat and the two first knobs 16 are loosened. At this time, the first connecting rod 14 and the second connecting rod 15 can be rotated, and the angle of the backrest 1 can be adjusted. After adjusting to the appropriate angle, lock the first knob 16, and the staff lies on it. The motor 4 drives the second gear 5 to rotate, and the second gear 5 drives the third gear 6 to rotate. The third gear 6 drives one of the first gears 2 to rotate. Since the multiple first gears 2 are engaged with each other, the multiple first gears 2 rotate together, and the multiple first gears 2 drive the multiple massage blocks 3 to rotate, thereby effectively massaging and relaxing the staff's back, having the function of buffering and decompression, improving the quality of the lunch break, and thus improving the efficiency of afternoon office work.

[0025] Step 2: The office chair can be moved conveniently through multiple universal wheels 13 to facilitate use by staff. The headrest 17 is used to support the head, and different staff members have different heights, so the position of the headrest 17 needs to be adjusted. When adjusting, first loosen the two second knobs 18. At this time, the headrest 17 can be adjusted. After adjusting to the appropriate position, lock the second knob 18 to improve practicality.

[0026] Compared with the related art, the cushioning and decompression office chair provided by the present invention has the following beneficial effects:

[0027] Long-term office work will cause fatigue to the staff. During the lunch break, the office chair backrest 1 is placed flat and the staff lies on it. The motor 4 drives the second gear 5 to rotate, and the rotation of the second gear 5 drives the third gear 6 to rotate. The rotation of the third gear 6 drives one of the first gears 2 to rotate. Since the multiple first gears 2 are engaged with each other, the multiple first gears 2 rotate together, and the multiple first gears 2 drive the multiple massage blocks 3 to rotate, thereby effectively massaging and relaxing the staff's back, having the function of buffering and decompression, improving the quality of the lunch break, and thus improving the efficiency of the afternoon office.
