Casters 122 are fixed to the bottom surface of the fixing plate 121. Casters 122 do not contact the ground when the seat is in use. Only when the back panel 1 is tilted will casters 122 contact the ground, which is convenient for carrying the seat out without affecting the stability of the seat.

[0027] Reference Figure 1 , Figure 2 and Figure 4 As shown, specifically, a support plate 11 is symmetrically fixed to one side wall of the lower end of the back panel 1 to fix and support the support shaft 111. The support shaft 111 is fixed to the side wall of the support plate 11 to connect and support the seat plate 2. The seat plate 2 is provided on one side of the back panel 1, and the user sits on the seat plate 2. One end of the seat plate 2 is provided with a rotating hole 24 so that the seat plate 2 can be flipped. The support shaft 111 passes through the rotating hole 24. A cushion 21 is fixed to the top surface of the seat plate 2. The cushion 21 is made of flexible material to increase the comfort during use. A support column 13 is symmetrically fixed to the top surface of the back panel 1 to support the backrest 14. The support column 13 has a backrest 14 fixed at its top, which allows the user to lean back when sitting. The backrest 14 has a finger groove 141 on its side wall, which makes it easy to hold the backrest 14 stably when carrying the chair. The finger groove 141 is located above the lifting groove 142. The seat 2 of this solution can be rotated 90 degrees upward with the support shaft 111 as the center, so that the seat 2 is in a vertical state and can be folded up for storage. By passing fingers through the finger groove 141 to hold the backrest 14, and then tilting the backrest 14 at a slight angle, the caster wheel 122 can be brought into contact with the ground, and the entire seat can be moved, making it convenient to carry when going out. Example 2

[0028] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 3As shown, specifically, a slot 22 is provided on one side wall of the seat plate 2 for inserting the L-shaped clamping plate 15 and restricting the rotation of the seat plate 2. A lifting groove 142 is provided in the middle of the bottom surface of the back plate 14 to accommodate the vertical movement of the lifting plate 144. A spring 143 is fixed to the top surface of the inner side of the lifting groove 142, which pushes the lifting plate 144 downward through elastic pushing force. The lower end of the spring 143 is fixed to the lifting plate 144, which can drive the lifting rod 145 to move up and down. The upper end of the lifting plate 144 is movably inserted into the inner side of the lifting groove 142. A lifting rod 145 is fixed in the middle of the bottom surface of the lifting plate 144 to drive the L-shaped clamping plate 15 to move up and down. A limit plate 146 is fixed to the lower end of the lifting rod 145 to prevent the L-shaped clamping plate 15 from falling downward. An L-shaped locking plate 15 is movably inserted on the outside to fix the seat plate 2. One end of the L-shaped locking plate 15 has a through hole 151, allowing the L-shaped locking plate 15 to rotate. The lifting rod 145 is movably inserted into the inside of the through hole 151 and passes through the through hole 151. In this design, after the seat plate 2 is vertical, the L-shaped locking plate 15 is moved upward, causing the lifting plate 144 to fully enter the inside of the lifting groove 142. The spring 143 is compressed, and then the L-shaped locking plate 15 is rotated 180 degrees. Under the downward pushing force of the spring 143, one end of the L-shaped locking plate 15 is inserted into the inside of the locking groove 22, which can lock the seat plate 2 and fix the seat plate 2, thereby improving the stability of the seat plate 2 during carrying and transportation, and is particularly suitable for long-distance carrying and transportation. Example 3

[0029] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 5As shown, specifically, a connecting plate 23 is fixed to the bottom surface of the seat plate 2 for connecting with the inclined plate 3. The side wall of the connecting plate 23 has a connecting hole 231 for connecting the rotating shaft 33. Inclined plates 3 are symmetrically arranged on both sides of the seat plate 2 to support it. A rotating shaft 33 is symmetrically fixed to the side wall of the inclined plate 3, allowing the inclined plate 3 to rotate. The rotating shaft 33 passes through the connecting hole 231. A threaded cylinder 232 is fixed to the middle of the bottom surface of the connecting plate 23 for connecting and moving the screw 233. The threaded cylinder 232 communicates with the inner side of the connecting hole 231. A screw 233 is threadedly connected to the inner side of the threaded cylinder 232, which restricts the rotation of the rotating shaft 33. The screw 233 passes through the threaded cylinder 232. The inclined plate 3... An auxiliary triangular plate 31 is fixed to the side wall to support the user's feet. The auxiliary triangular plate 31 is located on one side below the seat plate 2. An armrest 32 is fixed to the top of the inclined plate 3. The surface of the armrest 32 is made of flexible material to support the user's arms. This solution allows the two inclined plates 3 to rotate around the rotation axis 33. After the seat plate 2 is flipped to a vertical position, the two inclined plates 3 can also rotate to a vertical position to complete the storage of the two inclined plates 3. By turning the screw 233, one end of the screw 233 is pressed against the rotation axis 33 to limit the rotation of the rotation axis 33, thereby fixing the two inclined plates 3 and ensuring that the two inclined plates 3 will not rotate accidentally during carrying and transportation, thus improving stability and transportation safety.

[0030] The working principle and usage process of this utility model:

[0031] When in use, the user sits on the seat 2. The flexible seat cushion 21 enhances comfort, the two armrests 32 provide auxiliary support for the user's arms, and the auxiliary triangle 31 provides auxiliary support for the user's feet. When the chair needs to be taken out, by rotating the seat 2 upwards around the support shaft 111, the seat 2 can be flipped to a vertical position, located on one side of the backrest 1. At this time, by pushing the L-shaped locking plate 15 upwards, the lifting plate 144 is completely moved into the lifting groove 142, causing the spring 143 to be compressed. Then, the L-shaped locking plate 15 is rotated 180 degrees around the lifting rod 145 to release the L-shaped locking plate. Under the downward elastic force of the spring 143, one end of the L-shaped clamp 15 is inserted into the inner side of the clamp slot 22 to fix the seat plate 2. Then, the two inclined plates 3 are rotated to a vertical position with the rotating shaft 33 as the center. The screw 233 is turned and moves inside the threaded cylinder 232. One end of the screw 233 presses against the rotating shaft 33, which fixes the two inclined plates 3 after they are vertical. Finally, the fingers are inserted through the finger groove 141 to grasp the backrest 14 and the entire seat is tilted at a slight angle so that the casters 122 contact the ground. The seat can then be pulled to move, or it can be directly transported to a vehicle for transportation, which improves portability.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
