When the first connecting pipe abuts against the outer end of the inner side of the sliding hole, the first support rod and the second support rod are relatively unfolded, the seat cushion is laid flat, and the bar chair can be used normally. When the first connecting pipe moves towards the inner end of the inner side of the sliding hole in the sliding hole, the first connecting pipe pushes the seat cushion to rotate relative to the second support rod. When the first connecting pipe abuts against the inner end of the inner side of the sliding hole, the seat cushion fits against the backrest, realizing the folding of the seat cushion and the support rod. The folded bar chair is convenient for storage and transportation, can improve the space utilization rate and reduce the transportation cost.

[0038] Further, there are two cross beams 5, and the two cross beams 5 are symmetrically arranged at the bottom of the seat cushion 3, and the connecting piece is fixedly connected to the outer ends of the cross beams 5. In this technical solution, there are two symmetrically arranged cross beams, and thus two corresponding sliding holes are constructed, making the movement and support of the first connecting pipe more stable. It should be noted that the number of cross beams and the corresponding sliding holes can be set as required.

The inner end of the first half-threaded screw 10 is screwed with a first anti-loosening nut. In this technical solution, the use of the folding piece and the L-shaped piece facilitates the connection with the second support rod and at the same time makes it difficult for the seat cushion to touch the second support rod when rotating relative to the second support rod; the use of the first half-threaded screw facilitates the disassembly and assembly of the second support rod and the connecting piece.

[0040] Further, a first fixing plate 11 is fixedly arranged between the two cross beams 5 on the inner side of the bottom of the seat cushion 3, and a number of first screw holes 12 are correspondingly opened on the first fixing plate 11 and the seat cushion 3. In this technical solution, the setting of the first fixing plate can improve the installation structural stability of the cross beam, connect the two cross beams into a whole, and further make the first connecting pipe move more stably in the sliding hole.

[0041] Further, a second fixing plate 13 is fixedly arranged between the two cross beams 5 on the outer side of the bottom of the seat cushion 3, and a number of second screw holes 14 are correspondingly opened on the second fixing plate 13 and the seat cushion 3. In this technical solution, the setting of the second fixing plate further improves the installation structural stability of the cross beam, making the first connecting pipe move more stably in the sliding hole.

[0042] Further, the cross beam 5 includes a fixing portion 23 and a connecting portion 15. A number of third screw holes 16 are correspondingly formed on the fixing portion 23 and the seat cushion 3, and the connecting portion 15 is correspondingly connected to the U-shaped plate 6. In this technical solution, the connecting portion 15 and the U-shaped plate are correspondingly connected, that is, there is no corresponding U-shaped plate under the fixing portion of the cross beam, which facilitates the assembly of the fixing portion and the seat cushion.

[0043] Further, second connection holes are correspondingly formed on the first support rod 1 and the second support rod 2. The second half-threaded screw 17 is inserted into the second connection holes to connect the first support rod 1 and the second support rod 2, and a second anti-loosening nut is screwed on the inner end of the second half-threaded screw 17. A forging 18 is formed on the second half-threaded screw 17 between the first support rod 1 and the second support rod 2. In this technical solution, the use of the second half-threaded screw facilitates the disassembly and assembly of the first support rod and the second support rod. The forging improves the strength of the second half-threaded screw, making the support of the second half-threaded screw on the first support rod and the second support rod more reliable when the bar chair is unfolded for use, and improving the stability.

[0044] Further, a reinforcing rod 19 is fixedly provided between the lower portions of the two first support rods 1. In this technical solution, the arrangement of the reinforcing rod 19 improves the structural strength of the lower portion of the first support rod.

[0045] Further, a U-shaped rod 20 is welded between the lower portions of the two second support rods 2. In this technical solution, the arrangement of the U-shaped rod improves the structural strength of the lower portion of the second support rod and is convenient for users to rest their feet.

In this technical solution, the bottom surfaces of the first support rod 1 and the second support rod 2 are transverse fitting surfaces that abut against the ground, that is, a sheep's hoof type design, which can increase the contact area between the support rods and the ground and increase the stability.

[0047] In this specific embodiment, aiming at the problem that the existing conventional bar chair has a stable external structure and is not easy to store and carry, the above solution hinges the first support rod and the second support rod. The rear part of the seat cushion is hinged to the second support rod and is supported by the first half-threaded screw. The first connecting pipe supports the front part of the seat cushion and can move back and forth in the sliding hole. When the first connecting pipe abuts against the outer end of the inner side of the sliding hole, the first support rod and the second support rod are relatively unfolded, and the seat cushion is laid flat, and the bar chair can be used normally. When the first connecting pipe moves inward to the inner end of the sliding hole, the first connecting pipe pushes the seat cushion to rotate relative to the second support rod. When the first connecting pipe abuts against the inner end of the inner side of the sliding hole, the seat cushion fits against the backrest, realizing the folding of the seat cushion and the support rod. The folded bar chair is very convenient for storage and transportation, can improve the space utilization rate and reduce the transportation cost.
