Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a chair with easily disassembled armrests. Background Art

[0002] A chair is a basic piece of seating that allows people to sit down to rest or work instead of standing. It generally consists of a flat seat and a vertical or slightly inclined backrest, with four legs for support.

[0003] Chinese utility model patent CN221635358U discloses a control chair with comfortable riding. The control chair can push the adjustment part toward the connecting tube by screwing the adjustment bolt upward, so that the two connecting rods push the two adjustment tubes out of the two ends of the connecting tube respectively, thereby reducing the swing amplitude of the seat frame. Screwing the adjustment bolt downward can move the adjustment part downward, so that the two connecting rods pull the two adjustment tubes into the two ends of the connecting tube respectively, thereby increasing the swing amplitude of the seat frame, and improving the riding comfort by adjusting the amplitude of the reciprocating swing of the seat frame; however, in actual use, the control chair still has shortcomings. Since its supporting structures are all fixed, the overall space occupied is larger, so it is more suitable for use in a more spacious location. When used in an environment with a relatively small space, it will appear too crowded and not flexible enough, which may hinder the activities of people around or cause the user to feel cramped and uncomfortable. Utility Model Content

[0006] Furthermore, a pair of accommodating plates are symmetrically provided at the bottom of the seat frame, and accommodating racks are slidably provided on both accommodating plates, and a pressure spring is provided between the accommodating racks and the corresponding accommodating plates.

[0007] Furthermore, a backrest is rotatably provided at the rear of the seat frame, the backrest and the seat frame are staggered and fitted, and a spiral spring is provided between the backrest and the seat frame.

[0008] Furthermore, an inclined block and a shift block are slidingly provided in the backrest, the shift block is fixedly connected to the inclined block, and an elastic member is provided between the inclined block and the backrest; a slot adapted to the inclined block is provided on the mounting block, and when the backrest is rotated to fit in the misalignment with the seat frame, the inclined block is snapped into the slot.

[0009] Furthermore, it also includes a pull rope with a pull ring at the end, and the pull ring is sleeved on the traction rope on the same side.

[0010] Furthermore, a contact rod is provided in the middle of the pull rope. When the backrest is rotated to fit in a misaligned manner with the seat frame, the contact rod contacts the backrest and is pressed downward by the backrest.

[0011] The beneficial effects are as follows: the utility model designs the armrests to be insertable and removable, and fixes them with guide sleeves and insert blocks, so that users can easily install or remove the armrests as needed, which not only facilitates transportation and storage, but also allows the configuration of the chair to be quickly adjusted according to different usage scenarios; the combination of L-shaped insert rods and elastic parts ensures that the legs can be firmly mounted on the mounting blocks, and will not easily loosen or fall off even during use, thereby improving the stability of the entire chair, and the accommodating plate and accommodating frame arranged at the bottom of the seat frame, as well as the pressure spring design therebetween, can store the legs after the user removes them, reducing the space occupied and facilitating storage; through the design of pull ropes and traction ropes, users can easily complete the disassembly and assembly of the armrests without the use of additional tools, simplifying the operation process.
