Description

Technical Field

[0001] The utility model belongs to the technical field of furniture, in particular to a single-person sofa computer chair with adjustable height. Background Art

[0002] Whether in the office or at home, it is a habit for many young people to sit in front of the computer and work continuously without moving. After a long time, they will experience problems such as blurred vision and back pain. This is because if the height of the computer chair is not matched with the desk, it is easy to cause damage to the eyes and joints. The backrests of traditional computer chairs cannot be adjusted in angle, resulting in a lack of comfortable sleep during lunch break, affecting the work state in the afternoon. If this continues for a long time, it will fall into a vicious circle and affect physical health.

[0003] A good computer chair should not only be comfortable to sit on, but also have a high degree of freedom in the vertical and horizontal directions, that is, a large adjustable range. In order to solve the above problems, a single-person adjustable height sofa computer chair is proposed. Summary of the invention

The fixing block is snap-fitted with the rectangular groove, and the shape and size of the threaded column are adapted to the threaded groove, and the threaded column is threadedly connected to the threaded groove.

[0009] Limiting blocks are arranged at both ends of the slide bar, the slide groove is slidably matched with the slide bar, and the slide bar and the support tube are both "U"-shaped tubular structures.

[0010] The utility model has the following beneficial effects:

[0011] The utility model manually rotates the handle on the threaded column to rotate it out of the threaded groove. After rotating to a certain extent, the fixed block will disengage from the rectangular groove. At this time, the threaded column can be adjusted to a suitable position through the elongated groove, and then the seat back is pushed forward, and the rotating ring will push it into the first circular hole from the inclined surface of the second limit block, and then the seat back is pulled back to adjust to different angles. One end of the support component is hinged to one end of the hollow tube, and the other end of the support component is hinged to the seat back. The support component is a folding arm structure. At this time, the support frame is pulled open, and buttons on both sides of one end of the support tube in the hollow tube are pressed, so that the support tube can be pulled down. After adjusting a certain length, the button pops out from the through hole to support and fix it. At this time, the fixed support component will be unfolded, and the support component will form a triangular stable relationship with the seat back and the hollow tube. Finally, the slide rod is pulled out of the slide groove, and a rotating groove is arranged on the side surface of the slide rod. The rotating groove is hinged with a rotating rod, and then the support plate is flipped by the rotating rod to be laid flat.
