[0028] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, 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.

[0029] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] See also Figure 1-Figure 6The utility model designs a lifting chair, which includes a seat body 20 and a backrest 10. The backrest 10 includes a comfort layer 11 and a back plate 13. The comfort layer 11 is provided with a limiting opening 12. The back plate 13 is provided with an opening 14 and a limiting block 15. The limiting block 15 is clamped with the comfort layer 11 through the limiting opening 12. The back plate 13 and the comfort layer 11 are enclosed to form an accommodating cavity 19. The opening 14 is connected to the accommodating cavity 19. The first end of the seat body 20 is limited to the accommodating cavity 19 through the opening 14. The back plate 13 includes a first connecting hole 18. The seat body 20 includes a second connecting hole 22. The connecting piece passes through the first connecting hole 18 and the second connecting hole 22 to lock the backrest 10 and the seat body 20.

[0031] The back panel 13 and the comfort layer 11 of the utility model are connected by a snap-fit ​​method. When the comfort layer 11 is worn or aged, the user only needs to remove the current comfort layer 11 and replace it with a new comfort layer 11. There is no need to replace the entire backrest 10, which solves the problem of high maintenance costs. The back panel 13 and the comfort layer 11 are enclosed to form a accommodating cavity 19. The back panel 13 is provided with a first connecting hole 18 and an opening 14 connected to the accommodating cavity 19. The seat body 20 includes a second connecting hole 22. After the seat body 20 is extended into the accommodating cavity 19, the connecting piece can lock the seat body 20 and the backrest 10 through the first connecting hole 18 and the second connecting hole 22. When not in use, the connecting piece is disengaged from the first connecting hole 18 and the second connecting hole 22, and the seat body 20 is disengaged from the accommodating cavity 19, which can solve the problem of large volume occupied by the lifting chair in the prior art. Of course, it should be noted that the utility model can also set a limit opening 12 on the back panel 13 and a limit block 15 on the comfort layer 11, or realize a detachable connection between the back panel 13 and the comfort layer 11 through other forms, and the utility model does not limit this.

[0032] Specifically, the limit block 15 includes a connecting portion 16 and a protruding portion 17. The connecting portion 16 connects the protruding portion 17 and the back panel 13. The protruding portion 17 abuts against the comfort layer 11 through the limiting opening 12. The protruding portion 17 is an elastic member. When it is located at the limiting opening 12, the elastic member is pressurized. After passing through the limiting opening 12, the elastic member automatically returns to its original state and abuts against the comfort layer 11, thereby ensuring the connectivity between the comfort layer 11 and the back panel 13.

[0033] Specifically, the back plate 13 includes a plurality of first connection holes 18 , which are spaced apart along the height direction of the back plate 13 . The connecting member passes through the second connection hole 22 and any first connection hole 18 to lock the backrest 10 at any height of the seat body 20 .

[0034] Specifically, the seat body 20 includes a seat plate 23 and a connecting block 21 . The seat plate 23 is detachably connected to the connecting block 21 . The first end of the connecting block 21 extends into the backrest 10 through the opening 14 and is provided with a connecting hole.

[0035] The plurality of first connection holes 18 on the back plate 13 of the utility model are spaced apart along its height direction. By selecting the first connection holes 18 at different positions to cooperate with the second connection holes 22 on the back plate 13, the user can lock the backrest 10 at different heights of the seat body 20, thereby realizing personalized height setting.

[0036] Specifically, the lifting chair further includes an explosion-proof plate 24 , which is detachably connected to the seat plate 23 and the connecting block 21 .

[0037] Specifically, the lifting chair also includes a lever and a gas pressure rod 30. The bottom surface of the explosion-proof plate 24 is provided with a gas pressure rod hole 25. The first end of the gas pressure rod 30 is limited to the gas pressure rod hole 25. The lever includes a paddle and a handle 26. The paddle is hinged on the gas pressure rod 30 to form a lever, and the handle 26 is driven to drive the paddle to rotate.

[0038] Specifically, the lifting chair further comprises a bottom plate 31 , the bottom plate 31 is provided with a connecting hole, the second end of the gas pressure rod 30 is limited in the connecting hole and is rotatably connected to the bottom plate 31 .

[0039] Specifically, the lifting chair also includes a fixed rod, an elastic member and a spring cover 33. The seat plate 23 is provided with an escape hole, the fixed rod passes through the escape hole, the elastic member is wound around the fixed rod, and the spring cover 33 is threadedly connected to the fixed rod to seal the elastic member.

[0040] The user only needs to apply a certain amount of force through the handle 26 to drive the paddle to rotate, and the gas pressure rod 30 can drive the seat plate 23 to rise and fall to meet the user's demand for adjustable seat height. The bottom surface of the explosion-proof plate 24 is provided with a gas rod hole 25, and the gas rod hole 25 cannot be connected to the seat plate 23, ensuring the safety performance of the lifter. The fixed rod, elastic part and spring cover 33 constitute an adjustment button, which can adjust the tightness of the backrest 10. When in use, people can adjust it by themselves, and it is highly applicable. Of course, it should be noted that the paddle of the utility model drives the gas pressure rod 30 to rise and fall and the adjustment button adjusts the tightness of the backrest 10, which are all existing technologies, and the utility model does not limit this.

[0041] Specifically, in order to facilitate the movement of the lifting chair, the utility model further provides a steering wheel 32 , and the steering wheel 32 is connected to the bottom plate 31 .

[0042] Specifically, the lifting chair also includes a handle and a headrest. The headrest is detachably connected to the backrest 10, and the handle is connected to the seat plate 23 and is provided with a limiting groove for placing a water cup.

[0043] The headrest of the utility model provides head support for the user, and is detachably connected to the backrest 10, occupies a small volume for transportation, and the user can choose whether to install the headrest according to his or her needs and preferences. The handle allows the user to have a stable gripping point when standing up or sitting down, thereby improving the stability and safety of the entire lifting chair. The limit groove on the handle allows the user to conveniently place items such as water cups, and the utility model is highly applicable.
