[0002] Folding chairs are lightweight, stackable seats that are easy to move and save space. They are commonly used in various training institutions, schools at all levels, public places, hospitals, restaurants, hotels, companies, homes, and outdoor locations. Folding chairs are convenient to use; they can be easily folded up and stored when not in use, making them flexible and convenient to use overall.

[0003] However, folding chairs still take up a lot of space when folded due to the size of the chair panel and legs, making them inconvenient to store. Utility Model Content

[0004] To address the inconvenience of storing existing folding chairs, this application provides a chair that is easy to store.

[0005] The chair that is easy to store, as provided in this application, adopts the following technical solution:

[0006] A chair that is easy to store includes a first support plate and a second support plate. Connecting plates are provided on both sides of the joint between the first and second support plates, and both the first and second support plates are rotatably connected to the connecting plates. Two rotatable legs that can be rotatably unfolded and rotatably retracted are rotatably installed on the opposite sides of one side of the first and second support plates. A seat is fixed on one side of the first support plate, and a support rod is rotatably installed on one side of the second support plate. One end of the support rod can be rotatably locked inside the seat. A buckle is rotatably installed on one side of the second support plate away from the first support plate. The buckle is fastened to the side of the first support plate when the first and second support plates are folded relative to each other.

[0007] By adopting the above technical solution, when the entire chair is folded up, the first support plate and the second support plate can be folded relative to each other, and the legs are pressed against the surface of the first or second support plate when folded, thereby greatly reducing the volume of the chair panel and the legs, making the chair smaller when folded up and more convenient to store.

[0008] Optionally, one side of the first support plate and the second support plate are fixed with a locking block for locking the outrigger in the retracted state, and the side of the outrigger is provided with a slot that cooperates with the locking block.

[0009] By adopting the above technical solution, the outriggers are fixed during folding by using the locking cooperation of the slots and blocks.

[0010] Optionally, both sides of the card block are fixed with protruding ribs, and the inner side wall of the card slot is provided with a groove that matches the ribs, and the length of the card slot is greater than the length of the card block.

[0011] By adopting the above technical solution, the locking block uses the locking ribs on both sides to lock into the groove to achieve a mutual locking fit between the locking block and the groove.

[0012] Optionally, one end of the support leg is provided with two rotating support plates fixed on the first or second support plate, one end of the support leg is locked between the two rotating support plates, one end of the support leg is fixed with a rotating shaft installed on the rotating support plate near one end corner, and one end of the support leg is fixed with a hemispherical locking protrusion near the other end corner.

[0013] By adopting the above technical solution, when the outrigger is deployed, the outrigger rotates around the pivot, causing the locking protrusion to lock and fix it on the inner side of the two rotating support plates, thereby achieving fixation when the outrigger is deployed.

[0014] Optionally, one end of the buckle is rotatably mounted on the side of the second support plate, and a protruding locking platform is fixed on the surface of the buckle near the other end. The side of the first support plate is provided with a buckle groove that mates with the locking platform.

[0015] By adopting the above technical solution, when the first support plate and the second support plate are folded together, the buckle plate is locked in the buckle groove to lock and fix them, thereby achieving the locking of the first support plate and the second support plate when folding.

[0016] Optionally, a fixing plate is fixed on the side of the card holder away from the support rod, and a carding cavity is opened on the side of the card holder closer to the support rod.

[0017] By adopting the above technical solution, the card holder uses the card cavity to hold one end of the support rod, thereby cooperating with the support rod to support the first and second support plates in the unfolded state.

[0018] Optionally, a sleeve hole is provided on one side of the strut near one end, and a rotating column fixed to the second strut is inserted through the inner side of the sleeve hole.

[0019] By adopting the above technical solution, the strut is mounted on the second support plate by using the sleeve hole to fit onto the rotating column.

[0020] Optionally, a U-shaped handle is installed on one side of the first support plate, and guide sleeves are fitted on both legs of the handle. Baffles are fixed at the ends of both legs, and mounting edges are fixed on the sides of the guide sleeves.

[0021] By adopting the above technical solution, the two legs of the handle are inserted into the inside of the guide sleeve, which can be pulled out when the chair is folded up, making it easier to carry the folded chair and use it.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. When the entire chair is folded up, the first and second support plates can be folded relative to each other, and the legs are pressed against the surface of the first or second support plate when folded, which greatly reduces the volume of the chair panel and legs, making the chair smaller when folded up and easier to store.

[0024] 2. The seat uses a locking cavity to lock one end of the support rod, thereby cooperating with the support rod to support the first and second support plates in the unfolded state, making the unfolding operation of the chair more convenient;

[0025] 3. The two legs of the handle are inserted inside the guide sleeve, which can be pulled out when the chair is folded up, making it easier to carry and use the folded chair. Attached Figure Description
