[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: a portable outdoor folding chair, including a seat cushion 1, a folding frame 2 is fixedly connected to the outer side of the seat cushion 1, the folding frame 2 includes four support members, a front fixed plate, a movable rod and a rear fixed plate, the four support members are connected to each other by an axis, and the movable rod is movably connected to one end of the support member, the four support members can rotate around the rear, and the front fixed plate and the rear fixed plate rotate the movable rod, so that the folding chair can be folded, the above-mentioned folding frame 2 is similar to the folding member principle mentioned in the Chinese patent with announcement number CN220458955U (a portable folding chair), and the effect is the same. It is a simple technology existing in the field and will not be described in detail here. The upper end of the folding frame 2 is fixedly connected to the backrest 3, and the bottom end of the folding frame 2 is fixedly connected to the support plate 4.

[0032] Reference Figure 3-Figure 4 The bottom surface of the support tube 7 is higher than the bottom surface of the support plate 4. When the top surface of the support tube 7 is in contact with the top surface of the circular groove 5, the support tube 7 can be completely received in the circular groove 5.

[0033] A support limit unit is provided on the right side of the support cylinder 7, and the support limit unit includes a pull plate 97, and the pull plate 97 is provided on the right side of the support disk 4. A card slot 91 is provided on the right side surface of the support cylinder 7, and a groove 92 is provided on the right side inner wall surface of the circular groove 5. A spring 93 is fixedly connected to the right side inner wall surface of the groove 92, and a support block 94 is fixedly connected to the left end of the spring 93. When the support block 94 moves to the right, the spring 93 is squeezed, so that the spring 93 is compressed to generate elastic potential energy. The upper surface of the support block 94 is located at the same horizontal plane as the top surface of the circular groove 5, and the left side surface of the support block 94 is fixedly connected There is a clamping block 95, which is clamped with the inside of the clamping slot 91. In the initial state, the clamping block 95 is located in the clamping slot 91 to clamp and fix the support tube 7, and at the same time, it will squeeze the spring 93 so that the spring 93 is in a compressed state. The right end of the support block 94 is fixedly connected with a connecting rod 96. When the connecting rod 96 moves, it can drive the support block 94 and the clamping block 95 to move synchronously. The right end of the connecting rod 96 passes through the support disk 4, and the right end of the connecting rod 96 is fixedly connected to the left surface of the pull plate 97. When the pull plate 97 moves, it can drive the connecting rod 96 to move synchronously in a straight line in the left and right directions.

[0034] When the folding chair is unfolded for use, the pull plate 97 can be pulled to the right to drive the clamping block 95 to move to the right, releasing the clamping connection of the support tube 7. At this time, the support tube 7 will move downward under the action of gravity, and then the pull plate 97 is released to allow the support block 94 to move to the left under the elastic potential energy of the spring 93 to reach the top of the support tube 7. As the folding chair is placed on the ground, the support tube 7 will contact and support the ground to ensure the stability of the folding chair when in use. The support block 94 will limit the support tube 7 to prevent the support tube 7 from retracting into the circular groove 5 and causing the support plate 4 to be In contact with the ground, when the folding chair is folded after use, the folded chair is turned upside down, and the pull plate 97 is pulled to drive the support block 94 and the clamping block 95 to move to the right to release the limit on the support tube 7, so that the support tube 7 retracts into the circular groove 5 under the action of gravity, and then the pull plate 97 is released, so that the clamping block 95 moves to the left under the elastic potential energy of the spring 93 and enters the clamping groove 91 to resume the clamping connection. At this time, the support tube 7 in contact with the ground will enter the circular groove 5 for storage, so as to avoid contamination of the storage container when the folding chair is stored in a box or storage bag.

[0035] Reference Figure 2-Figure 3The bottom end of the support disk 4 is fixedly connected with a magnetic ring 10, and the magnetic ring 10 is embedded in the bottom end of the support disk 4. A protective plate 11 is arranged at the bottom end of the support disk 4. The protective plate 11 is made of iron material. The magnetic ring 10 can magnetically adsorb the protective plate 11. The protective plate 11 can shield the inside of the circular groove 5 to prevent impurities adhering to the bottom surface of the support cylinder 7 from falling. The upper surface of the protective plate 11 is in contact with the bottom surface of the magnetic ring 10. The upper end of the protective plate 11 is fixedly connected with a fixed ring plate 12. When the protective plate 11 moves, it can drive the fixed ring plate 12 to move synchronously. The fixed ring plate 12 is sleeved inside the circular groove 5. The upper surface of the fixed ring plate 12 fits with the bottom surface of the limit ring 8, and a scraper 13 is fixedly connected to the inside of the fixed ring plate 12. The upper end of the scraper 13 fits with the bottom surface of the support tube 7. When the protective plate 11 rotates, the scraper 13 can be driven to rotate. At this time, the scraper 13 can scrape off the impurities adhered to the bottom surface of the support tube 7, and the impurities will fall into the fixed ring plate 12 for collection. The bottom end of the seat cushion 1 is fixedly connected with a circular magnetic plate 14. When the folding chair is in use, the protective plate 11 can be removed by pressing it, and the protective plate 11 can be attached to the bottom end of the circular magnetic plate 14 for limit fixing, which is convenient for taking.

[0036] Working principle: When the folding chair is unfolded for use, the protective plate 11 is removed and placed on the circular magnetic plate 14 for limiting. The pull plate 97 is pulled to release the fixation of the support tube 7, so that the support tube 7 moves downward, and then the pull plate 97 is released so that the support block 94 limits the support tube 7. The support tube 7 can support the folding chair. After the folding chair is used, the folded chair is turned upside down, and the pull plate 97 is pulled again and then released, so that the support tube 7 can be retracted into the circular groove 5 for storage and clamped and limited to prevent the bottom of the folding chair from contacting the ground and adhering impurities, causing internal contamination of the storage device. Then the protective plate 11 is removed so that the fixed ring plate 12 is sleeved inside the circular groove 5 and rotated to scrape off the adhered impurities and shield the inside of the circular groove 5 to prevent impurities from falling out and causing pollution. The operation is simple.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
