Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figure 1 , an embodiment provided by the present utility model: a hidden adjustment structure, including a telescopic rod 18, a first air pressure chamber 20 is installed at the bottom of the telescopic rod 18, a second air pressure chamber 19 is provided on the outside of the first air pressure chamber 20, and an electric valve 21 is installed at the bottom of the first air pressure chamber 20.

[0028] Specifically, the telescopic rod 18 has a telescopic effect. When the user sits on the bar chair, the button 13 is pressed, the electric valve 21 is opened, the air pressure inside the first air pressure chamber 20 and the second air pressure chamber 19 gradually balances, the telescopic rod 18 slowly descends. When adjusted to a certain height, the button 13 is released, the electric valve 21 is closed, the air pressure inside the first air pressure chamber 20 is fixed, and the telescopic rod 18 reaches a stable state. When the user leaves the bar chair, the telescopic rod 18 slowly rises to the height where the air pressure inside the first air pressure chamber 20 is stable. The button 13 is pressed. Because the air pressure inside the second air pressure chamber 19 is greater than that inside the first air pressure chamber 20, when the air pressure inside the first air pressure chamber 20 is stable, the telescopic rod 18 will reach the highest height.

[0029] Refer to Figure 1 and Figure 2, a base 1 is fixedly connected to the bottom of the electric valve 21, and a connecting ring 10 is fixedly connected to the upper part of the base 1.

[0030] Specifically, the base 1 has the effect of lowering the center of gravity of the bar chair to prevent the bar chair from tipping over or falling, and the connecting ring 10 has the effect of connecting the textile cloth 9. The connecting ring 10 below the bearing 8 is fixedly connected to the bearing 8.

[0031] Refer to Figure 1 , a textile cloth 9 is fixedly connected to one side of the connecting ring 10.

[0032] Specifically, the textile cloth 9 has the effect of hiding the internal structure. When the telescopic rod 18 rises, the textile cloth 9 is stretched by the force in the vertical direction. When the telescopic rod 18 descends, the textile cloth 9 is pressed down by the force in the vertical direction.

[0033] Refer to Figure 2 、 Figure 3 and Figure 4 , the bar chair includes a hidden adjustment structure. A bearing platform 7 is provided at the top of the hidden adjustment structure. A card slot 6 is opened in the middle of the bearing platform 7. A rotating column 15 is rotatably connected to the middle of the bearing platform 7.

[0034] Specifically, the bearing platform 7 has the effect of providing installation conditions and support for other structures. The card slot 6 has the effect of preventing the seat plate 3 from tilting excessively. The connecting column 16, the connecting column 16, the torsion spring 17, and the fixed block 5 enable the seat plate 3 to be tilted by an external force, and after the external force disappears, the torsion spring 17 restores the seat plate 3 to its original position.

[0035] Refer to Figure 3 、 Figure 4 and Figure 5 , the partition assembly includes a back baffle 12. The bottom of the back baffle 12 is provided at the rear side of the bearing platform 7. A stop block 14 is opened on the front side of the back baffle 12.

[0036] Specifically, the back baffle 12 and the stop block 14 have the effect of blocking the seat plate 3 and the backrest 11.

[0037] Refer to Figure 3 and Figure 4 , a bearing 8 is rotatably connected to the bottom of the bearing platform 7.

[0038] Specifically, the bearing 8 enables the bearing platform 7 to rotate.

[0039] Refer to Figure 2 and Figure 3, a supporting plate 2 is fixedly connected to the front side of the seat plate 3, a backrest 11 is fixedly connected to the rear side of the seat plate 3, and a cushion 4 is fixedly connected to the front side of the backrest 11.

[0040] Specifically, the supporting plate 2 serves to bear the pressure exerted by the legs, the backrest 11 serves to bear the pressure exerted by the back, and the cushion 4 serves to improve the comfort of the back.

[0041] Refer to Figure 3 , a button 13 is installed on one side of the seat plate 3.

[0042] Specifically, the button 13 serves to control the opening and closing of the electric valve 21.

[0043] Working principle: The bar chair rotates through the bearing 8, adjusts the height through the telescopic rod 18, the first air chamber 20 and the second air chamber 19, and realizes the effect that the bar chair can recline backward through the seat plate 3, the supporting plate 2, the backrest 11, the rotating column 15, the connecting column 16, the torsion spring 17, and the bearing platform 7.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
