[0050] The working principle of the office chair with a buffer mesh back structure provided by the utility model is as follows:

[0051] When the user's back rests on the support backrest 21, the elasticity of the first support buffer net 22 buffers the pressure on the user's back. At the same time, there are many gaps on the surface of the first support buffer net 22, which plays a role in ventilation. In this process, the pressure on the patient's back causes the support backrest 21 to tilt toward the rear end, and the angle of the first transmission rod 44 changes. One end pulls the first sliding block 43 downward, and the spring in the first spring slide rod 42 is compressed by pressure, thereby playing a role in buffering and shock absorbing the support backrest 21. When the user needs to support the neck, first rotate the reverse threaded rod 61, and the two threaded blocks 62 face or are opposite to each other. The angle of the rotating rod 63 changes, and the other end drives the connecting rod 52 to move up and down, so that the connecting rod 52 drives the neck support assembly 3 to move up and down to a suitable position, and then the patient leans his neck on the support plate 31, and the elastic force of the second support buffer net 32 ​​buffers the patient's neck deformity and increases the air permeability and comfort. When the head is raised, the support plate 31 rotates under pressure, and the angle of the second transmission rod 73 changes, and one end drives the second sliding block 72 to move upward, and the spring in the second spring slide bar 71 is compressed, so that the support plate 31 can fit the patient, increase the comfort of the patient's neck, and also provide buffering.
