[0002] Bar stools, a common type of furniture in bars and restaurants, serve to enhance customer comfort and the atmosphere of the space. Traditional bar stools typically consist of fixed legs, a backrest, and a seat cushion. While their design provides some support and comfort, they also have some significant drawbacks:

[0003] (1) Cannot be folded or stored: Traditional bar chairs are designed to be fixed and cannot be folded or stored, which is especially inconvenient in bars or restaurants with limited space. For example, after closing, bar chairs need to be moved or stacked one by one, which is not only time-consuming and laborious, but also takes up a lot of space and affects the cleaning and tidying of the store.

[0004] (2) Non-adjustable height: Most traditional bar stools have a fixed height and cannot be adjusted to meet the specific needs of customers. This results in mismatched chair heights when used at bar counters or tables of different heights, reducing customer comfort and user experience. In particular, for customers with significant height differences, fixed-height chairs may cause them discomfort, affecting the overall service quality of the bar. Utility Model Content

[0025] The utility model provides a folding bar chair as shown in the accompanying Figures 1-7As shown in one folding bar chair, first leg frame 1, first leg frame 1 top end sliding sleeve has the second leg cylinder frame 2 and the second leg cylinder frame 2 is connected with first leg frame 1 through height limiting mechanism 3, the second leg cylinder frame 2 top is fixedly connected with backrest 4, the second leg cylinder frame 2 upper portion is fixedly connected with fixed frame 5, and fixed frame 5 one side is rotatably connected with seat cushion 6 and fixed frame 5 is equipped with two folding limiting mechanisms 7 that are limitedly matched with seat cushion 6. First leg frame 1, second leg cylinder frame 2, seat cushion 6 combination forms Z-shaped design, and seat cushion 6 both ends are rotatably connected with fixed frame 5 through damping bearing 8, and first leg frame 1 bottom is fixedly connected with two circular support pads 9 and two rectangular support pads 10, and first leg frame 1 is fixedly connected with foot support rod 11, and the circular support pad 9 and the rectangular support pad 10 at the bottom of the first leg frame 1 can effectively disperse the weight of the chair, improve the stability of the chair on the ground, prevent the chair from shaking in the process of use, the design of foot support rod 11 further enhances the overall structural stability of the chair, especially in the higher state, foot support rod 11 can provide additional support, prevent the chair from falling, improve the overall stability of the bar chair.

[0026] As Figure 1 , Figure 2 , Figure 5 As shown in the utility model, height limiting mechanism 3 includes installation groove 301 arranged in first leg frame 1, spring 302 is connected in first leg frame 1 at installation groove 301, one end of spring 302 is connected with limiting block 303 that is penetrated through the side wall of second leg cylinder frame 2, a plurality of limiting grooves 304 that are matched with limiting block 303 are arranged on the side wall of second leg cylinder frame 2, limiting block 303 can slide in limiting groove 304 under the action of spring 302, so that the adjustability of chair height is realized. When height needs to be adjusted, limiting block 303 is removed from the current limiting groove 304, then second leg cylinder frame 2 is slid to the required height, and limiting block 303 is clamped into the new limiting groove 304.

[0027] As Figure 6 and Figure 7As shown, the folding limiting mechanism 7 in the utility model comprises a steering guide rod 701 penetrating through the side wall of the fixed frame 5, the steering guide rod 701 is fixedly connected with a connecting block 702 at one end away from the seat cushion 6, the connecting block 702 is fixedly connected with a rotating ring 703 at one end away from the steering guide rod 701, the steering guide rod 701 is fixedly connected with a limiting clamping block 704 at one end, the connecting block 702 and the side wall of the fixed frame 5 are connected through a torsion spring 705 sleeved outside the steering guide rod 701, the side wall of the fixed frame 5 is provided with a semicircular side slot 706 for placing the limiting clamping block 704, the seat cushion 6 is provided with a clamping block through slot 707 for the limiting clamping block 704 to pass through and a semicircular inner slot 708 for the limiting clamping block 704 to rotate, the rotating ring 703 can drive the steering guide rod 701 and the limiting clamping block 704 to rotate and move together, thereby realizing the folding and unfolding of the seat cushion 6. When the chair needs to be folded, the rotating ring 703 is only rotated and pulled, the torsion spring 705 is stressed and the limiting clamping block 704 is separated from the semicircular inner slot 708, and then the seat cushion 6 is pushed to rotate around the damping bearing 8; when the chair needs to be unfolded, the seat cushion 6 is rotated to a horizontal state, the rotating ring 703 is pushed and rotated, the limiting clamping block 704 enters the semicircular inner slot 708, and the limiting clamping block 704 is rotated to limit the seat cushion 6 through the elastic force of the torsion spring 705, thereby realizing the unfolding of the chair.

[0028] Working principle:

[0029] 1Height adjustment process: when the height of the bar chair needs to be adjusted, the user first presses the limiting block 303 to separate it from the current limiting slot 304 and enter the fixed slot 301. Then, the user can slide the second leg cylinder 2 to adjust the chair to different height positions as needed. When the desired height is reached, the limiting block 303 is reinserted into the new limiting slot 304 under the action of the spring 302, ensuring the stability and reliability of the chair height.

[0030] 2Seat cushion folding process: when the bar chair needs to be folded, the user first rotates the rotating ring 703 to make the connecting block 702 drive the steering guide rod 701 and the limiting clamping block 704 to rotate together. The user continues to rotate the rotating ring 703 and pulls it, causing the limiting clamping block 704 to separate from the semicircular inner slot 708. Then, the user pushes the seat cushion 6 to rotate around the damping bearing 8, causing the seat cushion 6 to be close to the second leg cylinder 2.

[0031] 3Seat cushion unfolding process: when the bar chair needs to be unfolded, the user first pushes the seat cushion 6 to rotate around the damping bearing 8, causing the seat cushion 6 to be in a horizontal state, then pushes the rotating ring 703, causing the limiting clamping block 704 to separate from the semicircular side slot 706 and enter the semicircular inner slot 708 through the clamping through slot 707, and the limiting clamping block 704 is rotated in the semicircular inner slot 708 through the action of the torsion spring 705, thereby limiting and fixing the seat cushion 6, ensuring the stability of the seat cushion 6 and allowing the user to use the chair safely and comfortably.
