Abstract

The invention discloses a chair with a telescopic function, relates to the technical field of chairs, and solves the problems that a fulcrum of an existing chair is in the middle, the stability is poor, the situation of inclination is easy to occur, and stable rotation and use are not facilitated. The chair with the telescopic function comprises a seat plate, a through groove penetrating through the front side and the rear side is formed in the middle of the top of the seat plate, and a roller type cushion is rotatably arranged in the through groove; the roller type cushion is arranged outside the two sets of rollers in a sleeving mode, the roller type cushion is closed through a zipper, the roller type cushion is composed of a cotton cushion and a nylon net cushion, the sleeve legs and the inner legs are arranged, the number of fulcrums of the chair is increased to be four, the four fulcrums are used for bearing and fixing, stability is high, inclination is not prone to occurring, and compared with a single fulcrum, the stability is higher; meanwhile, the rotating function can be kept, and the position can be rotatably adjusted; and the adjusting speed can be increased through the combination of the synchronizing shaft and the transmission fluted disc, a power input component for rapidly controlling rising is provided, and the four sets of inner legs stretch out and draw back synchronously.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a chair with a retractable function. Background technique [0002] A seat is a seat with a backrest and armrests. The chairs used today generally have a telescopic cylinder in the middle, which can be rotated and raised with the middle pillar as the fulcrum. [0003] After retrieval, for example, the patent with the publication number CN213247879U discloses a chair with a telescopic length, including a main board, the rear side of the upper end surface of the main board is fixedly equipped with a first protrusion, and the front end of the first protrusion is provided with a first chute. A second chute is provided on the rear end of the first chute, a slide bar is slidably installed in the first chute, a slider is fixedly installed on the rear end of the slide bar, the slider is slidably connected to the second chute, and a pair of A second bump is fixedly installed on the rear sid...
