Multipurpose office chair capable of adjusting leaning height based on pulleys

Abstract

The invention relates to the technical field of office equipment, and discloses a multipurpose office chair capable of adjusting the leaning height based on pulleys. The multipurpose office chair comprises a chair back, the top of the chair back is rotatably connected with a fixed pulley, the periphery of the fixed pulley is surrounded by a nylon rope, and the bottom of the left end of the nylon rope is fixedly connected with a sliding block; and the bottom of the right end of the nylon rope is fixedly connected with a positioning cross rod, and the inner wall of the right end of the chair back is fixedly connected with a limiting frame. According to the multipurpose office chair capable of adjusting the leaning height based on the pulleys, the positioning cross rod is pressed and matched with transmission of the nylon rope, so that the sliding block drives a cushion frame to change the height, meanwhile, a screw rod is rotated, the supporting angle of a supporting frame is changed under transmission of a first connecting rod, and the use comfort is improved; and through rotating and leftward pushing the rotating rod, when abutting blocks are clamped on the upper side and the lower side of the rotating rod, the cushion frame completely extends out, a user enters the cushion frame, and the effect of isolating light interference when the user leans on the cushion frame for rest is achieved.

Description

technical field [0001] The invention relates to the technical field of office equipment, in particular to a multi-purpose office chair which can adjust the leaning height based on pulleys.
