[0016] Please see Figures 1-4 This utility model provides an embodiment of a portable folding chair for elderly care, comprising an outer frame plate 1, a first insertion groove 2 on the surface of the outer frame plate 1, an inner frame plate 3 rotatably connected to the inner sidewall of the first insertion groove 2, and the inner frame plate 3 fitting into the first insertion groove 2, a second insertion groove 4 on the surface of the inner frame plate 3, a seat plate 5 rotatably connected to the inner sidewall of the second insertion groove 4, and the seat plate 5 fitting into the second insertion groove 4, a locking groove 8 on the surface of the seat plate, a locking block 7 on the inner sidewall of the first insertion groove 2 fitting into the locking groove 8, and a handle groove 6 on the surface of the outer frame plate 1; through the hierarchical rotational cooperation of the outer frame plate 1, the inner frame plate 3, and the seat plate 5, combined with an elastic positioning structure, stable unfolding and convenient folding are achieved. In the initial state, the seat plate 5 is completely embedded in the second insertion groove 4 of the inner frame plate 3, and the inner frame plate 3 is completely embedded in the first insertion groove 2 of the outer frame plate 1. The overall flat shape facilitates storage and carrying. When unfolded, caregivers or the elderly can hold it stably through the handle groove 6 on the surface of the outer frame panel 1. First, rotate the inner frame panel 3 outward. The inner frame panel 3 rotates around the rotation axis of the inner side wall of the first insertion groove 2. Then, rotate the seat panel 5 outward. The seat panel 5 rotates around the rotation axis of the inner side wall of the second insertion groove 4. In the final unfolded state, the locking block 7 on the inner side wall of the first insertion groove 2 and the locking groove 8 on the surface of the seat panel 5 engage with each other to form a lock, thus completing the unfolding of the folding chair. When folding, first apply pressure to the seat panel 5 to separate the locking block 7 from the locking groove 8. Continue to rotate the seat panel 5 inward until it is completely embedded in the second insertion groove 4 of the inner frame panel 3 to complete the nesting. Then rotate the nested inner frame panel 3 inward and continue to rotate until the inner frame panel 3 is completely embedded in the first insertion groove 2 of the outer frame panel 1 to restore the initial flat state. At this time, it can be easily lifted or stored through the handle groove 6.

[0017] In this embodiment, both the bottom of the seat plate 5 and the bottom of the inner frame plate 3 are provided with embedding grooves 10. A return spring 11 is fixedly connected to the inner sidewall of the embedding groove 10. A semi-circular retaining ball 12 is fixedly connected to the movable end of the return spring 11, and the semi-circular retaining ball 12 is slidably connected to the embedding groove 10. A limiting groove 13 is provided on the inner sidewall of the embedding groove 10. A limiting block 14 is slidably connected to the inner sidewall of the limiting groove 13. The sidewall of the limiting block 14 is fixedly connected to the sidewall of the semi-circular retaining ball 12. The inner walls of the first insertion groove 2 and the second insertion groove 4 are both provided with arc grooves 9, and the arc grooves 9 fit with the semi-circular retaining ball 12. The outer frame plate 1, the inner frame plate 3, and the seat plate 5 are all made of nylon glass fiber reinforced material, and 900D Oxford cloth is bonded to the surface of the seat plate 5. During the folding and rotating process, the semi-circular retaining ball 12 in the embedding groove 10 is pressed into the embedding groove 10 and the return spring 11 is compressed simultaneously. When the outer frame plate 1, inner frame plate 3 and seat plate 5 are at the same level, the semi-circular ball 12 is precisely inserted into the arc groove 9 to complete the positioning. The cooperation between the limiting groove 13 and the limiting block 14 can effectively prevent the semi-circular ball 12 from falling out of the embedded groove 10 under the action of the return spring 11, ensuring the long-term reliability of the elastic positioning structure.

[0018] Through the hierarchical rotational cooperation of the outer frame plate 1, inner frame plate 3, and seat plate 5, combined with an elastic positioning structure, stable unfolding and convenient folding are achieved. In the initial state, the seat plate 5 is completely embedded in the second insertion groove 4 of the inner frame plate 3, and the inner frame plate 3 is completely embedded in the first insertion groove 2 of the outer frame plate 1, forming a flat shape for easy storage and carrying. When unfolded, caregivers or the elderly can hold the seat plate 5 stably through the handle groove 6 on the surface of the outer frame plate 1. First, rotate the inner frame plate 3 outward, and the inner frame plate 3 rotates around the rotation axis of the inner side wall of the first insertion groove 2. Then, rotate the seat plate 5 outward, and the seat plate 5 rotates around the rotation axis of the inner side wall of the second insertion groove 4. In the final unfolded state, the first insertion groove 4 is fully inserted into the inner frame plate 1. The locking block 7 on the inner side wall of the groove 2 and the locking groove 8 on the surface of the seat plate 5 engage with each other to form a locking mechanism, thus completing the unfolding of the folding chair. When folding, pressure is first applied to the seat plate 5 to separate the locking block 7 from the locking groove 8. The seat plate 5 is then rotated inward until it is fully embedded in the second insertion groove 4 of the inner frame plate 3 to complete the nesting. The nested inner frame plate 3 is then rotated inward again until it is fully embedded in the first insertion groove 2 of the outer frame plate 1 to restore the initial flat state. At this time, it can be easily lifted or stored through the handle groove 6. During the folding and rotating process, the semi-circular locking ball 12 in the insertion groove 10 is pressed into the insertion groove 10 and the return spring 11 is compressed simultaneously. When the outer frame plate 1, inner frame plate 3 and seat plate 5 are at the same level, the semi-circular locking ball 12 is just locked into the arc groove 9 to complete the positioning. The cooperation between the limiting groove 13 and the limiting block 14 can effectively prevent the semi-circular locking ball 12 from falling out of the insertion groove 10 under the action of the return spring 11, ensuring the long-term reliability of the elastic positioning structure.

[0019] Employing a nested folding structure of outer frame 1, inner frame 3, and seat 5, the chair folds into a single, flat, and compact shape. Combined with the handle groove 6 on the outer frame 1, it allows for easy lifting by caregivers. Whether for flexible movement within hospital wards, car storage during medical outings, or wall-mounted storage at home, it significantly saves space, effectively addressing the drawbacks of traditional folding chairs being bulky and difficult to carry. In terms of materials, the outer frame 1, inner frame 3, and seat 5 are all made of nylon fiberglass reinforced material. This material combines lightweight and high strength, making it easy for the elderly or caregivers to operate. The fiberglass reinforcement structure also enhances the material's rigidity and aging resistance, preventing deformation and breakage over long-term use. The 900D Oxford cloth bonded to the surface of the seat 5 possesses excellent wear resistance, water resistance, and stain resistance, easily handling water stains and dirt during caregiving, and is easy to clean. The seat is easy to use and has a soft touch, significantly improving the comfort of elderly people. The mechanical positioning of the locking block 7 and the locking groove 8, combined with the elastic positioning of the semi-circular locking ball 12 and the arc groove 9, forms a double fixation, ensuring a stable seat structure without wobbling or displacement after unfolding. This effectively supports the weight of the elderly, reducing the risk of tipping over. The elastic positioning structure automatically engages during rotation, eliminating the need for additional locking operations and simplifying the unfolding and folding process. This design is suitable for the elderly, who often have limited mobility, making operation convenient and effortless. The reliable structural design also extends the product's lifespan. The limiting groove 13 embedded in the groove 10, in conjunction with the limiting block 14, effectively limits the semi-circular locking ball 12, preventing the return spring 11 from detaching due to prolonged extension and contraction. Furthermore, the nylon fiberglass reinforced material has excellent corrosion resistance, making it suitable for humid environments such as hospitals and restrooms, further extending the product's service life.
