Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1 - 3, a portable folding chair, comprising a fixed frame 1. At the upper ends of both sides of the inner wall of the fixed frame 1, first resistance rotating shafts 2 are fixedly connected. A first rotating rod 3 is rotatably connected between the two first resistance rotating shafts 2. At the lower end of the surface of the first rotating rod 3, a support frame 4 is fixedly connected. At the upper ends of both sides of the inner wall of the support frame 4, second resistance rotating shafts 5 are fixedly connected. A second rotating rod 6 is rotatably connected between the two second resistance rotating shafts 5. At the lower end of the surface of the second rotating rod 6, a seat board 7 is fixedly connected. On both sides of the front surface of the fixed frame 1, placing grooves 8 are opened.

[0022] In the present utility model, a fixing rod 9 is rotatably connected inside the placing groove 8. Insertion slots 10 are opened on both sides of the support frame 4 and at one end of the fixing rod 9. At one end of the fixing rod 9, an insertion rod 11 adapted to the insertion slot 10 is inserted. On the upper surface of the fixed frame 1, a placing box 12 is fixedly connected. On the upper surface of the placing box 12, a placing cover 13 is hinged through a hinge. On the upper surface of the placing box 12, two collecting grooves 14 are opened. Through the arrangements of the placing box 12 and the collecting grooves 14, the insertion rod 11 is stored.

[0023] At the middle ends of both sides of the inner wall of the fixed frame 1, support blocks 15 are fixedly connected. On the front surface of the seat board 7, a soft pad 16 is fixedly connected. The material of the soft pad 16 is rubber. Through the arrangement of the support blocks 15, the seat board 7 is supported. Through the arrangement of the soft pad 16, the device is more comfortable to use.

[0024] When the present utility model is used, first, the seat board 7 is rotated through the second rotating rod 6 inside the second resistance rotating shaft 5 of the support frame 4 until a suitable angle is reached. Secondly, the support frame 4 is rotated through the first rotating rod 3 inside the first resistance rotating shaft 2 of the fixed frame 1 until a certain angle is formed between the fixed frame 1 and the support frame 4. At the same time, the lower end of the seat board 7 contacts the support block 15 inside the fixed frame 1. Then, the fixing rod 9 inside the placing groove 8 is rotated until the insertion slot 10 at one end of the fixing rod 9 coincides with the insertion slot 10 of the support frame 4. The placing cover 13 is opened, and the insertion rod 11 is taken out from the collecting groove 14 inside the placing box 12. The insertion rod 11 is inserted into the insertion slot 10. As Figure 2 shown, the fixed frame 1 and the support frame 4 are thus fixed. Finally, when storage is required, the insertion rod 11 is taken out and placed into the placing box 12. The seat board 7 and the support frame 4 are rotated again to restore the device to a flat state, as Figure 1 shown.

[0025] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
