Description

Technical Field

[0001] The utility model relates to a chair, in particular to a folding chair. Background Art

[0002] A chair is a kind of daily furniture, which is widely used indoors and outdoors, providing a comfortable seat for people to work, study, have meetings and relax. In order to facilitate the storage and transportation of idle chairs, manufacturers generally set them in a foldable state. With the continuous development of technology, there are more and more styles and types of folding chairs on the market.

[0003] For the existing folding chairs, although they can be folded to reduce the occupied space, they are relatively loose after being folded as a whole, and the folding parts are easy to fall off from the main body, which brings troubles to users. Summary of the Utility Model

[0004] Based on this, it is necessary to provide a folding chair aiming at the deficiencies in the prior art.

[0005] The technical solution of the utility model is as follows: a folding chair, which includes a board main body, an upper cover installed on the board main body, a first functional board slid on the board main body, a second functional board, a connecting piece connecting the first functional board and the second functional board, a first magnetic buckle group, a second magnetic buckle group, a third magnetic buckle group, and a fourth magnetic buckle group. The first magnetic buckle group and the second magnetic buckle group have the same magnetism, the third magnetic buckle group and the fourth magnetic buckle group have the same magnetism, the first magnetic buckle group and the third magnetic buckle group have opposite magnetism.

[0034] When the folding chair is switched to the use state, slide the first functional plate 20 downward. The latch 22 of the first functional plate 20 slides synchronously in the adjustment slot 12 until the card slot reaches the bottommost position of the adjustment slot 12. Rotate the second functional plate 30 until the second card surface 34 of the second functional plate 30 catches the second limiting surface 24 of the first functional plate 20. At this time, the first functional plate 20 and the second functional plate 30 are perpendicular to each other, and the first functional plate 20 is perpendicular to the plate body 10. At this time, the user can sit on the first functional plate 20. Preferably, the present utility model further includes a buffer pad 100. When the folding chair is switched to the use state, the buffer pad 100 can be snapped into the receiving groove 11 above the first functional plate 20 to act as a backrest and provide comfort during use.

[0035] When the folding chair is switched to the folded state, rotate the second functional plate 30 and the first functional plate 20 until the first card surface 33 of the second functional plate 30 abuts against the first limiting surface 23 of the first functional plate 20.
