Detailed Description
The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.
Example 1. A conference chair with adjustable armrests is shown in figures 1-4 and comprises a chair body 1, wherein fixing seats 2 are arranged on two sides of the chair body 1, the fixing seats 2 are connected with first armrest seats 4 through electric telescopic rods 3, sliding rails 5 in the front-back direction are arranged at the upper ends of the first armrest seats 4, second armrest seats 7 with sliding blocks 6 are arranged at the upper ends of the sliding rails 5, armrests 8 are rotatably arranged at the upper ends of the second armrest seats 7, first ratchet mechanisms 10 are arranged at the front ends of the armrests 8, and second ratchet mechanisms 11 are arranged at the rear ends of the armrest 8.
The first ratchet mechanism 10 comprises a first external-meshing type ratchet 12, a first pawl 13 corresponding to the first external-meshing type ratchet 12 is arranged inside the first external-meshing type ratchet 12, and a first driving lever 14 is arranged on the first pawl 13.
The ratchet direction of the second ratchet mechanism 11 is opposite to that of the first ratchet mechanism 10.
The slide block 6 is a T-shaped slide block, and the slide rail 5 is provided with a slide groove corresponding to the slide block 6.
The upper end of the second armrest seat 7 is provided with a rotating rod 15, and the inside of the armrest 8 is provided with a mounting hole corresponding to the rotating rod 15.
