[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0018] A flip-type variable single and double seat, such as Figure 1-Figure 4As shown, it includes a connecting frame 1, a handle 2, a screw rod 3, a locking gear 4, a first locking column 5, a first spring 6 and a single and double adjustment component. The front part of the connecting frame 1 is rotatably connected to the screw rod 3, the left side of the screw rod 3 is connected to the handle 2, the left part of the screw rod 3 is connected to the locking gear 4, the left side of the connecting frame 1 is slidably connected to the first locking column 5, the first locking column 5 is locked with the locking gear 4, the rear part of the first locking column 5 is toothed, which is convenient for locking with the locking gear 4, the first spring 6 is connected between the first locking column 5 and the connecting frame 1, and the screw rod 3 is provided with a single and double adjustment component.

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a seat 7, a movable frame 8, a connecting half frame 9, a second clamping frame 10 and a second spring 11. The movable frame 8 is threadedly connected to the screw rod 3, and the rear part of the movable frame 8 is slidably connected to the connecting frame 1. The left and right parts of the movable frame 8 are rotatably connected to the seat 7. The seat 7 is M-shaped. The left front and rear sides of the left part of the left seat 7 are connected to the connecting half frame 9, and the right front and rear sides of the right part of the right seat 7 are also connected to the connecting half frame 9. The lower part of the connecting half frame 9 is a semicircular arc structure, which is convenient for limiting and supporting the seat 7. The front connecting half frame 9 is in contact with the screw rod 3, and the rear connecting half frame 9 is in contact with the connecting frame 1. The left front and rear sides of the right seat 7 are slidably connected to the second clamping frame 10, and the second clamping frame 10 is connected to the right seat 7 with a second spring 11, and the second clamping frame 10 is clamped with the left seat 7.

[0020] When using the utility model, first connect the connecting frame 1 to the use area of ​​the seat 7. When the single seat 7 needs to be used, the second locking frame 10 is slid to the right, so that the second spring 11 is squeezed and contracted, so that the second locking frame 10 is separated from the left seat 7, and then the right seat 7 is rotated and raised on the moving frame 8. After the rotation of the right seat 7 is completed, the second spring 11 rebounds, so that the second locking frame 10 slides and re-engages with the left seat 7, so that the left seat 7 is locked and fixed to the table and chair on the right. When single use is required, the user sits on the table and chair on the left, and the right seat 7 becomes a cushion for the user to lean on. When the single cushion seat 7 needs to be further expanded, the first locking column 5 is slid backward to separate from the locking gear 4, the first spring 6 is squeezed and contracted, and then the screw rod 3 is rotated through the handle 2, so that the seat 7 When the double seat 7 is needed, the leftmost seat 7 is disassembled, and the first locking column 5 is slid backward to disengage from the locking gear 4, and the screw rod 3 is rotated to reset the seat 7, and then the second locking frame 10 is disengaged from the left seat 7, and then the right table and chair are put down and reset, so that the left and right seats 7 are placed side by side, and the connecting half frame 9 supports the seat 7 to turn it into a double seat 7, thereby being able to be flipped and adjusted according to the needs of the user, realizing the transformation from a single seat 7 to a double seat 7, so as to adapt to different usage occasions and improve the space utilization rate.

[0021] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
