Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-4 , a lunch break chair backrest with a segmented folding structure, including a chair seat 10 and a chair backrest 3. The front and rear ends of the chair backrest 3 are clamped with a rotating seat 5. The bottom of the rotating seat 5 is connected with a backrest support leg 18. A magnetic attraction block 17 is embedded in the left bottom of the backrest support leg 18. An adjustment handle 1 is installed on the left side of the front and rear ends of the chair backrest 3. The bottom of the adjustment handle 1 is installed with a rear support leg 6 and a front support leg 15. A connecting rotating rod 7 is installed at the front end of the right side of the rear support leg 6;

[0024] The rear support leg 6 is connected and rotated with the chair surface fabric 8 through the connecting rotating rod 7. The backrest support leg 18 rotates on the right side of the chair backrest 3 through the rotating seat 5. The backrest support leg 18 on the left side of the backrest support leg 18 is magnetically fixed to the right side of the chair backrest 3. The chair backrest 3 is connected to the top of the rear support leg 6 through the adjustment handle 1;

[0025] Specifically, as shown in Figure 1 and Figure 2As shown in the figure, by setting a segmented folding structure, when in use, the chair backrest 3 and the chair seat 10 are rotated and unfolded. At the same time, the chair backrest 3 rotates through the connecting rotating rod 7 and the rear support leg 6, so that the adjusting handle 1 moves through the rotation of the chair backrest 3 with the front support leg 15 and the rear support leg 6. At the same time, the backrest support leg 18 on the right side of the chair backrest 3 is separated from the seat cushion 13 through the magnetic block 17, and the backrest support leg 18 rotates through the rotating seat 5 to extend and support the right side of the chair backrest 3, thus realizing the segmented folding function.

[0026] Embodiment 2: A fixed clamping ring 20 is sleeved on the top of the chair backrest 3. A storage belt 4 is connected to the right side of the fixed clamping ring 20, and a magic tape 19 is arranged at the bottom of the storage belt 4;

[0027] The storage belt 4 is connected to the chair backrest 3 through the fixed clamping ring 20, and the fixed clamping ring 20 is sleeved outside the top end of the chair backrest 3;

[0028] Specifically, as Figure 1 and Figure 3 shown in the figure, by setting a convenient storage structure, when the chair backrest 3 and the rear support leg 6 are folded through the front support leg 15 and the rear support leg 6 during use, the storage belt 4 on the right side of the fixed clamping ring 20 at the top of the chair backrest 3 can pass through the inner cross bar 22 inside the chair seat 10. After that, the storage belt 4 is wound around the inner cross bar 22 and then adhered to each other through the magic tape 19 outside the storage belt 4, which is convenient for moving and storing the lunch break chair, thus realizing the convenient storage function.

[0029] Embodiment 3: Sliding grooves 12 are installed at the front and rear of the chair seat 10. An extension sliding rod 14 is inserted into the inside of the sliding grooves 12. An inner support plate 23 is installed inside the extension sliding rod 14. A clamping groove 21 is opened at the bottom right of the inner support plate 23, and an inner cross bar 22 is inserted into the left side inside the chair seat 10;

[0030] The extension sliding rod 14 slides inside the sliding grooves 12, and the extension sliding rod 14 is placed at the bottom of the chair seat 10 through the inside of the sliding grooves 12. The inner support plate 23 rotates inside the extension sliding rod 14, and the clamping groove 21 on the right side of the inner support plate 23 is clamped with the inner cross bar 22 inside the left side of the seat cushion 13;

[0031] Specifically, as Figure 1 and Figure 4 shown in the figure, by setting a seat extension structure, when in use, the extension sliding rod 14 is slid inside the sliding grooves 12, and the extension sliding rod 14 is pulled out from the bottom of the chair seat 10 through the sliding grooves 12. Then, the inner support plate 23 inside the rotating extension sliding rod 14 is rotated, so that the clamping groove 21 on the right side of the inner support plate 23 is clamped with the inner cross bar 22 inside the seat cushion 13, and the inner support plate 23 extends the chair seat 10, thus realizing the seat extension function.

[0032] Working principle: When the present utility model is in use, the chair backrest 3 and the chair seat 10 are rotated and unfolded. At the same time, the chair backrest 3 rotates through the connecting rotating rod 7 with the rear support leg 6, enabling the adjustment handle 1 to move with the front support leg 15 and the rear support leg 6 through the rotation of the chair backrest 3. Meanwhile, the backrest support leg 18 on the right side of the chair backrest 3 is separated from the seat cushion 13 through the magnetic block 17, allowing the backrest support leg 18 to rotate through the rotating seat 5 to extend and support the right side of the chair backrest 3. Then, the extension slide rod 14 slides inside the sliding groove 12, and the extension slide rod 14 is pulled out from the bottom of the chair seat 10 through the sliding groove 12. After that, the inner support plate 23 inside the rotating extension slide rod 14 is rotated, enabling the clamping groove 21 on the right side of the inner support plate 23 to be clamped with the inner cross bar 22 inside the seat cushion 13, allowing the inner support plate 23 to extend the chair seat 10. The headrest 2 is sleeved on the left side of the chair backrest 3, and at the same time, the seat cushion 13 is placed on the top of the chair seat 10. After use, when the chair backrest 3 and the rear support leg 6 are folded through the front support leg 15 and the rear support leg 6, the storage belt 4 on the right side of the fixed snap ring 20 at the top of the chair backrest 3 can be passed through the inner cross bar 22 inside the chair seat 10. Then, after the storage belt 4 is wound around the inner cross bar 22, it is adhesively connected to each other through the magic tape 19 outside the storage belt 4, facilitating the movement and storage of the lunch break chair.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
