Detailed ways

As shown in Figures 1 and 2, an armrest structure of an office chair includes a support base 1 and an armrest 2. Armrests 2 are installed on both sides of the support base 1. The armrest 2 is composed of a support member 3 and a rotating member 4. The support base 1 The support member 3 is integrally arranged on the support base 1. The support member 3 and the rotating member 4 are movably connected through a rotating shaft. The end of the rotating member 4 is connected to the support plate 6 through the swinging member 5. The swinging member 5 has a built-in push block 7 , the end of the push block 7 is against the swing piece 8, and the two legs 9 at the end of the swing piece 8 are against both sides of the slider 10. The back of the slider 10 is arranged in an arc shape and has a chute 11 on the back. 11 is engaged with the rack 13 at the end of the lifting block 12. The bottom of the lifting block 12 is provided with a stepped groove 14. The stepped groove 14 is engaged with the engaging groove 15 in the inner cavity of the support member 3. The push block 7 drives the swing The piece 8 drives the chute 11 on the slide block 10 to swing along the rack 13 on the lifting block 12 .
