[0031] Specifically, the outer surfaces of the two front support rods 7 are hinged with inner support rods 5 for improving stability, and one end of the two inner support rods 5 is hinged with a connecting plate 4. The hinged seats at which the front support rod 7 and the rear support rod 2 are hinged with the folding rod 3 can slide on the outer surfaces of the front support rod 7 and the rear support rod 2, and the outer surfaces of the front support rod 7 and the rear support rod 2 are fixedly connected to the limiting seat 6, and the lower surface of the connecting block 805 is fixedly connected with a connecting snap ring 806, and the inner diameter of the connecting snap ring 806 is the same as the diameter of the rear support rod 2, and the bottom end of the connecting sleeve 807 is movably connected to the top end of the front support rod 7, and the length of the first telescopic rod 802 and the second telescopic rod 804 extended by the telescopic sleeve 803 does not exceed the length from the rotating ring 801 to the limiting seat 6, and the rotating ring 801 can rotate on the outer surface of the rear support rod 2 without sliding longitudinally.

[0032] Furthermore, when the folding chair is folded and opened, the folding rod 3 is rotated and opened through the hinge seat, and the hinge seat is driven to slide on the outer surfaces of the front support rod 7 and the rear support rod 2. Through the setting of the limit seat 6, the hinge seat will no longer slide after sliding to the position of the limit seat 6, thereby fixing the opening angle of the folding rod 3. After the folding chair is opened, the connecting clamp ring 806 is separated from the outer surface of the rear support rod 2, so that it is rotated through the hinge seat between the first telescopic rod 802 and the rotating ring 801, and the rotating ring 801 is rotated on the outer surface of the rear support rod 2. , thereby driving the connecting block 805 and the connecting sleeve 807 to rotate to the top end position of the front support rod 7. During the rotation process, the telescopic ladder tube and the second telescopic rod 804 are adjusted to allow the connecting block 805 and the connecting sleeve 807 to extend to the position of the front support rod 7. The connecting sleeve 807 cooperates with the top end of the front support rod 7 to fix the armrest assembly 8 to achieve the function of the armrest. An inner support rod 5 is provided between the two front support rods 7, and the two inner support rods 5 are connected by a hinged connecting plate 4, thereby playing a certain stabilizing role after the folding chair is opened.

[0033] Example 2

[0034] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. The stabilizing component 9 includes a connecting ring 901 fixedly connected to the outer surfaces of the front support rod 7 and the rear support rod 2. The outer surface of the connecting ring 901 is hinged with a rotating rod 902 through a hinge seat. The end of the rotating rod 902 away from the connecting ring 901 is hinged with a connecting cylinder 905 through a hinge seat. A rotating cylinder 906 is inserted into the interior of the connecting cylinder 905. The lower surface of the rotating cylinder 906 is fixedly connected to an L-shaped connecting rod 904. The interior of the connecting cylinder 905 is provided with a coil spring 907 fixedly connected to the outer surface of the rotating cylinder 906. One end of the L-shaped connecting rod 904 is inserted into the interior of the rotating rod 902.

[0035] Specifically, the rotating cylinder 906 passes through the upper surface of the connecting cylinder 905 and is fixedly connected to the rotating block 903. The L-shaped connecting rod 904 passes through one end of the rotating rod 902 and forms an arc with the same radius as the rotating cylinder 906. The outer surface of the rotating rod 902 is provided with an arc hole that matches the L-shaped connecting rod 904. The lower surface of the connecting cylinder 905 is provided with an arc groove for the rotation of the L-shaped connecting rod 904. One end of the L-shaped connecting rod 904 is inserted into the interior of the rotating rod 902.

[0036] Furthermore, during the process of opening the folding chair, the rotating block 903 is rotated, thereby driving the L-shaped connecting rod 904 to disengage from the rotating rod 902 through the rotating cylinder 906, so that the rotating rod 902 loses its limit, thereby facilitating the folding and opening of the folding chair. When the folding chair is opened, the rotating block 903 is released, and driven by the coil spring 907, the rotating cylinder 906 drives the L-shaped connecting rod 904 to insert into the interior of the rotating rod 902, thereby limiting the rotating rod 902. The fixing function between the front support rod 7 and the rear support rod 2 is realized through the four rotating rods 902, thereby improving stability.

[0037] Working principle: When using the folding chair, during the process of folding and opening, the rotating block 903 is rotated, thereby driving the L-shaped connecting rod 904 to disengage from the rotating rod 902 through the rotating cylinder 906, so that the rotating rod 902 loses its limit, thereby facilitating the folding and opening of the folding chair. When the folding chair is opened, the rotating block 903 is released, and driven by the coil spring 907, the rotating cylinder 906 drives the L-shaped connecting rod 904 to insert into the interior of the rotating rod 902, thereby limiting the rotating rod 902. The four rotating rods 902 are used to fix the front support rod 7 and the rear support rod 2, thereby improving stability. During the opening process of the folding chair, the two inner support rods 5 are also rotated. Through the setting of the connecting plate 4, the two inner support rods 5 are rotated to a horizontal position, thereby fixing the two front support rods 7, thereby improving stability. After the folding chair is opened, the connecting clamp ring is connected to the rear support rod 2. 806 is separated from the outer surface of the rear support rod 2, so that it rotates through the hinge seat between the first telescopic rod 802 and the rotating ring 801, and rotates on the outer surface of the rear support rod 2 through the rotating ring 801, thereby driving the connecting block 805 and the connecting sleeve 807 to rotate to the top end position of the front support rod 7. During the rotation process, the connecting block 805 and the connecting sleeve 807 are extended to the position of the front support rod 7 through the adjustment of the telescopic ladder pipe and the second telescopic rod 804, and the armrest assembly 8 is fixed by the cooperation of the connecting sleeve 807 with the top end of the front support rod 7. Compared with the existing X-type folding chair which lacks the function of the armrest, the armrest assembly 8 realizes the function of the armrest and improves the comfort. The load-bearing cloth 1 set between the front support rod 7 and the rear support rod 2 plays the function of the seat surface, and finally the use of the folding chair is realized.
