Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a new multifunctional portable folding chair, comprising an armrest rod 1, the top end of the outer wall of the armrest rod 1 is hinged with a backrest rod 2, and the backrest rod 2 is folded and brought close to the top end of the armrest rod 1 by providing a hinged backrest rod 2, so that the backrest rod 2 can be folded, and the armrest rod 1 is provided with two groups, and the outer walls of the bottom ends of the two groups of armrest rods 1 are hinged with an articulated seat 6, and a connecting column 7 is rotatably connected between the two groups of articulated seats 6. By providing the articulated seat 6, the positions of the connecting column 7 and the upper connecting block 8 can be installed and placed, and a woven pad 5 is provided on the surface of the backrest rod 2 and the two groups of connecting columns 7, which is sewn and sleeved on the two groups of connecting columns 7 and the outer wall of the backrest rod 2 through the connecting column 7, so that it is convenient for people to sit.

[0032] Reference Figure 3 The inner sides of the two sets of hinged seats 6 are hinged with hinged rods 11. A recess is provided in the middle of the right hinged rod 11 to prevent the sliding of the sliders a12 on both sides from contacting each other and being blocked by sliding. The surfaces of the two sets of hinged rods 11 are slidably connected with sliders a12. The outer walls of the sliders a12 are hinged with fixed rods 13. The two sets of sliders a12 can slide on the surfaces of the hinged rods 11, so that when the two sets of hinged rods 11 rotate around the hinged seat 6 and gradually approach each other, the two sets of sliders a12 will synchronously drive the fixed rods 13 away from each other. The surface of the fixed rod 13 is slidably connected with sliders b14. By providing a fixed rod 13, it can prevent the slider b14 from positioning it when it moves, so that it will be fixed when it moves to the maximum limit. At this time, the whole is in an expanded state. The slider b14 is hinged at the end of the right hinged rod 11. By providing the slider b14, when the two groups of hinged rods 11 are expanded or approached to each other, the slider b14 will drive the fixed rod 13 to rotate, so that the fixed rod 13 drives the slider a12 to slide on the surface of the hinged rod 11. The two groups of hinged rods 11 are hinged to each other, and the end of the slider b14 away from the fixed rod 13 is fixedly connected to the connecting seat 15.

[0033] Reference Figure 3 and Figure 4The outer sides of the two sets of hinged seats 6 are detachably mounted with reinforcing rods 10. By providing two sets of reinforcing rods 10, the overall structure can be strengthened and fixed. At the same time, objects such as tables can be expanded on their surfaces through bolts. The outer sides of the two sets of reinforcing rods 10 are provided with hole grooves that fit in with the intersection 6, so that the reinforcing rods 10 can be positioned and installed. The surface of the connecting column 7 is slidably connected to the upper connecting block 8. When the connecting column 7 is folded and unfolded, it will synchronously drive the upper connecting block 8 to move up and down, so that the lower rod body 23 will be retracted on the inner wall of the upper rod body 21. When the whole is folded, the lower rod 23 extends outward to the maximum length on the inner wall of the upper rod 21, and the outer side wall of the connecting seat 15 is fixedly connected to the lower support rod 16. The surface of the lower support rod 16 is detachably mounted with a lower connecting block 9 by bolts. The rear end of the lower connecting block 9 is provided with bolts, and the lower connecting block 9 can be disassembled and installed by the bolts. At the same time, it is fixed to the surface of the lower support rod 16 by the lower connecting block 9, so that when the whole is folded, the lower connecting block 9 follows the lower support rod 16 to descend, which will drive the surface-hinged lower rod 23 to extend outward on the inner wall of the upper rod 21.

[0034] Reference Figure 3 and Figure 4The inner wall of the fixing rod 13 is slidably connected to a sliding rod 17 through a limit assembly a, and the sliding rod 17 is slidably connected to the inner wall of the connecting seat 15. An empty slot that fits the sliding rod 17 is opened on the left side of the inner wall of the connecting seat 15, so that the sliding rod 17 can move on the inner wall of the connecting seat 15, and the sliding rod 17 is slidably connected to the inner wall of the fixing rod 13. The sliding rod 17 can extend the inner wall of the fixing rod 13 through the sliding rod 17, so that a certain group of sliding rods 17 can be adjusted according to the height of different placement positions, so as to adjust the overall horizontal placement. The end of the sliding rod 17 is hinged with a support seat 18, and the support can be adjusted according to the angle of different placement positions through the rotatable support seat 18. The limiting assembly a includes a locking block 19, which is elastically connected to the inner wall of the top end of the connecting seat 15 by a limit spring 20. The locking block 19 is slidably connected to the inner wall of the top end of the connecting seat 15, and the limit spring The locking member 19 is fixedly secured to the top of the inner wall of the locking block 19, and the other end of the limiting spring 20 is fixedly secured to the surface of the inner side of the connecting seat 15. The limiting spring 20 is configured to automatically reset the locking block 19 after it is pressed, so that the lower end of the left outer wall of the locking block 19 contacts the surface of the sliding rod 17. The lower left end of the locking block 19 is provided with a cam shape, and the cam contacts the surface of the sliding rod 17, so that the sliding rod 17 can be extended to multiple positions for contact positioning, thereby fixing it. The inner wall of the bottom end of the upper connecting block 8 is detachable with an upper rod body 21. The upper connecting block 8 and the upper rod body 21 are both plastic parts. Through the split design, the upper rod body 21 and the lower rod body 23 can be disassembled and replaced as a whole when they are damaged. At the same time, the installation method of the upper connecting block 8 and the upper rod body 21 is a plug-in and rotatable installation. The inner wall of the upper rod body 21 is slidably connected to the lower rod body 23 through the limiting component b.

[0035] Reference Figure 3 and Figure 5The outer wall of the handrail rod 1 is detachably mounted with a placement plate 3 and a fixing block 4 by bolts. Bolts and positioning blocks are provided on the outside of the placement plate 3, which can be fixed to both sides of the handrail rod 1 by bolts, and an empty groove is opened on the surface of the placement plate 3, so that coasters can be placed, so that water cups and the like can be inserted into the coasters, and some items can be placed on its surface. There are two groups of fixing blocks 4, and annular blocks are provided on its surface. By installing the two groups of fixing blocks 4, the protective rope can be passed through the surface of one group and wound out from the rear end of the other group of backrest rods 2, so that the back support effect can be increased at the vacancies on both sides of the handrail rod 1. The limiting component b includes a clamping block 24, which is arranged on the inner wall of the top of the lower rod body 23, and the clamping block 24 is clamped with the side wall of the upper rod body 21, and the two are connected. The lower end of the outer wall of the lower rod 23 is hinged to the surface of the lower connecting block 9, and by providing the hinged lower rod 23 and the lower connecting block 9, the lower connecting block 9 will push the lower rod 23 to automatically extend on the inner wall of the upper rod 21 when the whole is folded.

[0036] Working principle: When the chair is to be unfolded, the backrest rod 2 is rotated outward from the folded state close to the top of the armrest rod 1. At the same time, the two sets of hinged rods 11 are rotated outward around the hinge seat 6 to unfold. During the unfolding process of the hinged rod 11, due to the connection between the slider b14 and the fixed rod 13, the slider b14 will drive the fixed rod 13 to rotate, and the fixed rod 13 will drive the slider a12 to slide away from each other on the surface of the hinged rod 11. As the slider a12 slides, the fixed rod 13 gradually unfolds and supports the backrest. In the entire structure, the connecting column 7 drives the upper connecting block 8 to move upward during the expansion process, so that the lower rod 23 contracts on the inner wall of the upper rod 21 until the lower rod 23 moves to the end on the inner wall of the upper rod 21, and the clamping block 24 is clamped in the current position of the upper rod 21. When the slider b14 drives the fixed rod 13 to rotate to a certain extent and the slider b14 slides to the maximum on the fixed rod 13, the entire structure is in a fully expanded state. At this time, the chair can be used for people to sit, and the fabric pad 5 provides a comfortable sitting or lying surface.

[0037] When the chair needs to be folded, the above process is reversed, the backrest rod 2 is folded towards the top of the armrest rod 1, and the two groups of buttons 22 are pressed to push the block 24 to move on the inner wall of the lower rod body 23. At the same time, the two groups of hinged rods 11 are rotated inward around the hinge seat 6. In this process, the slider b14 drives the fixed rod 13 to rotate in the opposite direction, and the slider a12 slides on the surface of the hinged rod 11 in the direction of approaching each other. The fixed rod 13 is gradually retracted, and the connecting column 7 drives the upper connecting block 8 to move downward. The lower connecting block 9 follows the lower support rod 16 to descend, and the lower connecting block 9 pushes the lower rod body 23 to extend outward on the inner wall of the upper rod body 21 until the chair is folded into a compact state, which is convenient for carrying and storage.

[0038] When the support height of the chair needs to be adjusted to adapt to different ground surfaces or usage requirements, the locking block 19 is pressed, and the locking block 19 overcomes the elastic force of the limit spring 20 and moves upward, breaking away from the contact with the surface of the sliding rod 17. At this time, the sliding rod 17 can be pulled or pushed to extend or retract on the inner wall of the fixed rod 13. Since the end of the sliding rod 17 is hinged to the support seat 18, changing the extension length of the sliding rod 17 also changes the height of the support seat 18, thereby adjusting the horizontal placement height of the entire chair. After adjusting to the appropriate height, release the locking block 19, and the locking block 19 returns to its original position under the action of the limit spring 20. Its cam shape contacts the surface of the sliding rod 17, contacting, positioning and fixing the extended position of the sliding rod 17 to maintain stable support of the chair.

[0039] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
