[0026] The dustproof component 5 is used to isolate the front side of the seat cushion 1 from dust.

[0027] For further information, see Figure 2 and Figure 3 In this embodiment, the dustproof component 5 includes a rectangular box 501, a slide rail 502, a slide plate 503 and a slide column 504. The rectangular box 501 is installed on the back of the back plate 3, the slide rail 502 is symmetrically installed on the inner wall of the rectangular box 501, the slide plate 503 is installed inside the rectangular box 501, and the slide column 504 is installed on the left and right sides of the slide plate 503 at positions corresponding to the slide rail 502. When the dining chair is used, it needs to be stored to free up space, so that the area of ​​the restaurant is not squeezed. When the seat cushion 1 is in a state of being folded, the seat cushion 1 and the first bracket 2 and the second bracket 4 are rotated by pushing the seat cushion 1 upward, and the folding is completed, so that the seat cushion 1 and the back plate 3 are convenient for storage and arrangement. At this time, the seat cushion 1 and the back plate 3 are in a vertical state, and the slide plate 503 is pulled downward to make the slide column 504 slide inside the slide rail 502, so that the slide column 504 slides to the bottom end of the slide rail 502, so that the inner side of the slide plate 503 is completely fitted with the seat cushion 1, and the seat cushion 1 is covered by the slide plate 503, effectively preventing dust from being adsorbed on the seat cushion 1.

[0028] Among them, see Figure 2 and Figure 3 In this embodiment, the slide plate 503 is slidably connected to the rectangular box 501 through a slide column 504, a handle 505 is installed on the outside of the slide plate 503, and an anti-slip pattern is provided in the middle of the handle 505. A magnetic strip 506 is installed on the top of the slide plate 503, and a cleaning roller 507 is installed on the side of the slide plate 503 away from the handle 505. When the seat cushion 1 is used normally, the magnetic property of the magnetic strip 506 is used to achieve the fit between the slide plate 503 and the rectangular box 501. By holding the handle 505 and pulling it downward, the operation is repeated to make the cleaning roller 507 contact with the seat cushion 1 to clean the dust.

[0029] Furthermore, please see Figure 1 , Figure 2 and Figure 4 In this embodiment, a silicone sleeve 6 is installed at the bottom of the first bracket 2 and the second bracket 4, and a connecting piece 7 is installed between the first bracket 2 and the second bracket 4. The connecting piece 7 is composed of a rotating shaft 701 and a fixing sleeve 702. The rotating shaft 701 is respectively installed inside the first bracket 2 and the second bracket 4, and the fixing sleeve 702 is installed outside the rotating shaft 701. Through the design of the silicone sleeve 6, when the first bracket 2 and the second bracket 4 contact with the bottom plate, their sharp parts are blocked by the silicone sleeve 6 to prevent scratching the bottom plate. Through the action of the connecting piece 7, the second bracket 4 moves closer to the first bracket 2, and the first bracket 2 and the second bracket 4 are folded.

[0030] Furthermore, please see Figure 1 , Figure 2 and Figure 4 In this embodiment, a stabilizing bar 8 is installed between the first bracket 2 and the second bracket 4, and a rotating column 9 is installed inside the first bracket 2 and the second bracket 4. The first bracket 2 and the second bracket 4 are connected to the seat cushion 1 through the rotating column 9. The stabilizing bar 8 greatly improves the stability of the first bracket 2 and the second bracket 4 when they are in contact with the ground. The design of the rotating column 9 enables the seat cushion 1 to complete the folding action. At the same time, since one end of the seat cushion 1 is folded, its rotational force is transmitted to the rotating column 9, so that the second bracket 4 is fitted with the first bracket 2 to complete the overall folding action.

[0031] For further information, see Figure 1 , Figure 2 and Figure 4In the present embodiment, a plurality of groups of air holes 101 are provided inside the seat cushion 1, and the plurality of air holes 101 are distributed at equal intervals. A bonding plate 10 is installed at the bottom of the seat cushion 1, and a plug 11 is installed inside the bonding plate 10, and the plug 11 extends to the inside of the second bracket 4. Through the design of the air holes 101, when the buttocks touch the seat cushion 1 in hot weather, the air holes 101 allow the inside of the seat cushion 1 to contact the outside world, and will not cause stuffiness and sweating, thereby greatly improving the comfort. When the seat cushion 1 is unfolded, the plug 11 is moved to move inside the bonding plate 10, and finally stuck into the inside of the second bracket 4, thereby completing the fixation of the seat cushion 1, and preventing the seat cushion 1 from folding as a whole when a child climbs on it, thereby causing injury to the child.

[0032] For further information, see Figure 1 and Figure 2 In this embodiment, a sponge pad is installed on the front of the back plate 3, a fixing plate 12 is symmetrically installed on the outside of the first bracket 2 and below the rotating column 9, an armrest 13 is installed on the top of the fixing plate 12, a rotating seat is installed between the fixing plate 12 and the armrest 13, and the fixing plate 12 is connected to the armrest 13 through the rotating seat. The sponge pad greatly improves the comfort when the back plate 3 contacts the back of the human body, and the rotating seat makes the armrest 13 swing, which increases its flexibility and is suitable for different people to adjust the angle of the hand frame for comfort.

[0033] In this embodiment, the implementation scenario is specifically as follows: when the dining chair needs to be stored after use to free up space, the design of the rotating column 9 is used to push the seat cushion 1 upward so that the seat cushion 1 completes the folding action. At the same time, since one end of the seat cushion 1 is folded, its rotational force is transmitted to the rotating column 9, so that the second bracket 4 is fitted with the first bracket 2 to complete the overall folding action. At this time, the seat cushion 1 and the backboard 3 are in a vertical state, and the handle 505 is pulled downward to make the sliding column 504 slide inside the sliding rail 502, so that the slide plate 503 moves downward, so that the inner side of the slide plate 503 is completely fitted with the seat cushion 1, and the seat cushion 1 is covered by the slide plate 503 to effectively prevent dust from being adsorbed on the seat cushion 1, and then repeatedly During operation, the cleaning roller 507 contacts with the seat cushion 1 to clean the dust. When the seat cushion 1 is used normally, the magnetic property of the magnetic strip 506 is used to make the slide plate 503 fit with the rectangular box 501. The stabilizing rod 8 greatly improves the stability of the first bracket 2 and the second bracket 4 when they are in contact with the ground. The plug 11 is moved to move inside the fitting plate 10 and finally snap into the inside of the second bracket 4 to fix the seat cushion 1. This prevents children from climbing on the seat cushion 1 and causing the entire seat cushion 1 to fold, thereby causing injuries to the children. The design of the silicone sleeve 6 blocks the sharp parts of the first bracket 2 and the second bracket 4 when they are in contact with the bottom plate to prevent the bottom plate from being scratched.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
