[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] like Figures 1 to 8 As shown, this embodiment discloses a folding moon chair comprising an upper base 1 and a lower base 2. The upper base 1 is hingedly connected to a plurality of lower support legs 3, and the lower base 2 is hingedly connected to a plurality of upper support legs 4 and a plurality of backrest tubes 5. The lower base 2 is provided with a plurality of leg retaining holes 25 for the lower support legs 3 to pass through one by one. The upper base 1 and the lower base 2 are detachably connected. In the folded state, the upper base 1 and the lower base 2 are separated from each other, and the lower support legs 3 are folded inwardly close to the lower base 2. The upper support legs 4 and the backrest tubes 5 are folded around the upper base 1. The folded moon chair is compact in size, and the lower ends of the lower support legs 3 are inserted into the lower base 2 without falling apart, making it easy to carry in a bag and can be placed upright.

[0030] The upper base 1 includes an unlocking cover 11, an upper base 12, and a locking shaft 13. The upper base 12 is provided with a plurality of first receiving slots 121 for accommodating one end of the lower support leg 3. One end of the lower support leg 3 is hingedly connected to the wall of the first receiving slot 121 in which it is located. The upper base 12 is provided with a through hole, and the unlocking cover 11 is rotatably mounted on the top of the upper base 12. The locking shaft 13 includes a shaft and a boss 16 connected to the lower end of the shaft. The shaft is connected to the middle of the top surface of the boss 16. The shaft is fixedly connected to the unlocking cover 11 and passes through the through hole in the upper base 12. The locking shaft 13 rotates synchronously with the unlocking cover 11.

[0031] Specifically, the upper base 1 also includes a gasket 14. The top surface of the unlocking cover 11 protrudes to form a handle 15. A groove for accommodating the gasket 14 is provided in the middle of the handle 15, and a non-circular hole (e.g., square, triangular, hexagonal, elliptical, etc.) is provided in the middle of the bottom of the groove. The upper end shape of the shaft of the locking shaft 13 (preferably square) matches the non-circular hole (preferably square). The shaft is a stepped shaft with a smaller top and a larger bottom. The through hole of the upper seat 12 matches the stepped hole of the shaft. The stepped surface of the shaft rests on the stepped surface of the stepped hole. The top of the shaft is provided with a threaded hole. A screw is passed through the gasket 14 and then locked into the threaded hole on the shaft to achieve the connection between the unlocking cover 11, the upper seat 12, and the locking shaft 13. In other embodiments, the connection method of the unlocking cover 11, the upper seat 12, and the locking shaft 13 is not limited to this. For example, it can also be achieved by welding, snap connection, etc.

[0032] Several positioning beads 17 are installed on the top surface of the upper seat 12, preferably two positioning beads 17 distributed at 180°, and several positioning holes 18 are provided on the bottom surface of the unlocking cover 11, preferably four positioning holes 18 symmetrical in pairs. Through the cooperation of the two positioning beads 17 and the four positioning holes 18, the unlocking cover 11 is fixed once every 90° rotation.

[0033] The top surface of the unlocking cover 11 is provided with a mark for indicating the rotation direction. By rotating the handle 15, the locking shaft 13 rotates synchronously with the handle 15. The top surface of the upper base 12 is also provided with a plurality of protrusions 19, and the bottom surface of the unlocking cover 11 is provided with a plurality of ribs 20. The protrusions 19 and the ribs 20 cooperate to limit the rotation angle of the unlocking cover 11.

[0034] The lower base 2 includes a lower seat 21, which is provided with a plurality of second receiving slots 26 for accommodating the ends of the upper support legs 4 or the backrest tubes 5. The openings of the second receiving slots 26 extend from the top surface of the lower seat 21 to the side surfaces. The ends of the lower support legs 3 and the backrest tubes 5 are hingedly connected to the walls of the second receiving slots in which they are located. A lower cover 22 is mounted on the bottom of the lower seat 21 to protect the bottom surface of the lower seat 21 from dust and sand.

[0035] The lower seat 21 is provided with a locking hole 23, and the inner wall of the locking hole 23 is provided with two opposite limiting protrusions 24. The locking hole 23 passes through the top surface of the lower seat 21, and the boss 16 of the locking shaft 13 is inserted into the locking hole 23 from between the two limiting protrusions 24 and rotated a certain angle. The two limiting protrusions 24 are restricted between the boss 16 and the bottom surface of the upper seat 12. In this way, the connection between the locking shaft 13 and the lower seat 21, that is, the connection between the upper base 1 and the lower base 2 is realized. By rotating the locking shaft 13, the locking shaft 13 is pulled out of the locking hole 23, so that the upper base 1 and the lower base 2 can be separated.

[0036] An extension tube 6 is detachably connected to the end of the backrest tube 5 away from the lower base 2. The extension tube 6 and the backrest tube 5 cooperate to form a high-back structure suitable for a wider range of people. Specifically, the backrest tube 5 and the extension tube 6 are connected by a connecting tube 9. The connecting tube 9 is inserted into the backrest tube 5 and the extension tube 6 at both ends. The connecting tube 9 is fixedly connected to the backrest tube 5 or the extension tube 6. The hole-shaft fit achieves the height increase of the backrest, while also ensuring the stability of the folding chair.

[0037] The upper support leg and the extension tube 6 are both connected with a ball stud 7 at one end away from the lower base 2. One end of the ball stud 7 is inserted into the extension tube 6 or the upper support leg and the other end is spherical. A foot pad 8 is installed at one end of the lower support leg 3 away from the upper base 1.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate from the spirit and scope of the technical solutions of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present invention.
