[0002] A folding chair is a seat that is lightweight, convenient to carry, and has a stacking function. The characteristics of a folding chair are that it is convenient to move and saves space. The main materials are Oxford cloth, plastic plates, etc. It was originally used for military purposes, but now it is commonly used in training institutions, companies, hotels and other places.

[0003] Most of the existing folding chairs use two support rods to support the chair through the lever principle. Since the folding chair is not clamped and fixed, the stability of the folding chair is not very good, which may lead to the phenomenon of people falling when sitting on the folding chair. For the elderly, falling may cause more serious consequences. Moreover, most of the backrests of the existing folding chairs are not convenient to adjust, and it is not convenient to accommodate people of different heights, and the backrest is not easy to reach a more comfortable position. Therefore, a folding chair with a stabilizing mechanism is proposed. Content of the Utility Model

[0025] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0026] Referring to Figures 1-4 , in an embodiment of the present invention, a folding chair with a stabilizing mechanism includes a seat board 1 and a backrest 3. A sponge pad is fixedly connected to the upper side of the seat board 1 to increase comfort. A cushion 31 is fixedly connected to the outer side of the backrest 3, and the inner side is a smooth plane. A stabilizing block 4 is fixedly connected to the lower side of the seat board 1. There are two stabilizing blocks 4, and they are arranged in parallel. A rotating shaft 7 is rotatably connected between the two stabilizing blocks 4 on both sides. A first U-shaped support frame 5 is hinged on the rotating shaft 7. The arc end of the first U-shaped support frame 5 is located at the lower side and is fixedly connected with an anti-slip sleeve 13 to increase stability.
