DETAILED DESCRIPTION

[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] In a specific embodiment, Figure 1-Figure 4 As shown:

[0032] An elastic base 1 and a fixing plate 2 fixedly mounted at the lower end of the elastic base 1;

[0033] A fixing rod 3 is fixedly installed at an equal angle on the lower end of the fixing plate 2, and a telescopic cylinder 4 is slidably installed on the outer side of the fixing rod 3, and a connecting ring 5 is fixedly installed on the outer side of the fixing rod 3, a supporting rod 6 is slidably installed inside the elastic base 1, and a backrest pillow 7 is threadedly installed on the upper end of the supporting rod 6.

[0034] When using the one-piece leisure chair with a stretching function, first place the leisure chair at the position where work is required. After the leisure chair is placed at the required position, you can sit on the upper end of the elastic base 1 and lean your back against the back pillow 7. The elastic base 1 and the back pillow 7 are provided with elastic sponges inside, which can improve the comfort of using the leisure chair. The shape of the leisure chair is different from that of a traditional leisure chair, which effectively improves the aesthetics of the leisure chair.

[0035] In one specific embodiment, Figure 1-Figure 5 As shown:

[0036] The lower end of the elastic base 1 is provided with a lifting structure, and the lifting structure can achieve the effect of adjusting the height of the leisure chair;

[0037] A fixed cylinder 8 and a threaded rod 9 are provided inside the lifting structure. The fixed cylinder 8 is fixedly installed inside the fixed plate 2, and the threaded rod 9 is threadedly installed inside the fixed cylinder 8, and a moving ring 11 is fixedly installed outside the threaded rod 9, and a rotating member 10 is fixedly installed at the lower end of the threaded rod 9;

[0038] A connecting rod 12 is fixedly installed at an equal angle on the outer side of the moving circle 11 , and a fixing ring 13 is fixedly installed on one end of the connecting rod 12 away from the moving circle 11 , and the fixing ring 13 is fixedly connected to the telescopic cylinder 4 .

[0039] Before using the one-piece leisure chair with stretching function, the height of the leisure chair needs to be adjusted according to needs. In the process of adjusting the height of the leisure chair, the user needs to rotate the rotating part 10. During the rotation of the rotating part 10, the threaded rod 9 will rotate inside the fixed tube 8. During the rotation of the threaded rod 9, the threaded rod 9 will move downward inside the fixed tube 8. The threaded rod 9 will make the telescopic tube 4 move downward on the outside of the fixed rod 3 through the moving ring 11 and the connecting rod 12, thereby changing the distance between the telescopic tube 4 and the elastic base 1, completing the height adjustment process of the leisure chair, and effectively improving the convenience of using the leisure chair.

[0040] It is worth mentioning that Figure 1 -and Figure 3-Figure 7 As shown:

[0041] An adjustment structure is arranged inside the elastic base 1, and the adjustment structure can achieve the effect of adjusting the position of the backrest pillow 7;

[0042] The adjustment structure is provided with a moving groove 14 and a moving member 19 inside. The elastic base 1 is provided with a moving groove 14 inside, and the moving member 19 is slidably installed inside the moving groove 14.

[0043] Two sets of connecting ropes 15 are fixedly installed on the outer side of the moving part 19, and a limit clamp 17 is fixedly installed on one end of the connecting rope 15 away from the moving part 19, and the limit clamp 17 is slidably installed inside the elastic base 1;

[0044] A support spring 18 is fixedly installed on one side of the limit clamp 17 close to the moving part 19, and two groups of the connecting rope 15, the limit clamp 17 and the support spring 18 are symmetrically arranged front and back about the vertical center axis of the elastic base 1;

[0045] Four groups of limit slots 16 are equidistantly formed on one side of the support rod 6 close to the middle of the elastic base 1 , and the limit slots 16 are engaged with the limit clamps 17 .

[0046] After the height of the leisure chair is adjusted, the user can adjust the position of the backrest pillow 7 according to his or her needs, thereby adjusting the leaning angle of the user when sitting on the upper end of the elastic base 1, and then the position of the backrest pillow 7 can be adjusted. In this process, the user needs to press the moving part 19, and the moving part 19 will pull the limiting clamp 17 to move through the connecting rope 15 during the movement. After the movement, the limiting clamp 17 will move away from the limiting slot 16, and the limiting clamp 17 will squeeze the supporting spring 18 during this process and cause the supporting spring 18 to contract. After the limiting card 17 is separated from the limiting card slot 16, the support rod 6 can slide inside the elastic base 1. The movement of the support rod 6 will drive the backrest pillow 7 to move. After the backrest pillow 7 moves to the required position, the moving part 19 can be released. At this time, the contracted support spring 18 will expand and push the limiting card 17 to engage with the limiting card slot 16 again, thereby engaging and limiting the support rod 6 inside the elastic base 1. At this point, the stretching and adjustment process of the leisure chair is completed, which effectively improves the comfort of using the leisure chair and increases the overall practicality.
