[0028] Reference Figure 1 and Figure 2As shown, bar stools are a derivative product developed and produced in the chair industry in recent years. Bar stools mainly consist of common office chair accessories such as gas springs, trays, and casters, as well as unique accessories such as horn plates and seat boards. Most existing bar stools, once installed at the bar counter, have a fixed position and relatively fixed shape, resulting in a lack of height adjustment after sitting. This significantly reduces comfort for users of different heights. To solve this problem, an adjustable-height bar stool is proposed, including a mounting base 1. A fixed shaft is rotatably connected to the bottom of the mounting base 1. A cushioning pad 16 is fixedly connected to the bottom of the fixed shaft. Four support frames 13 are fixedly connected to the bottom of the cushioning pad 16. A connecting seat 11 is fixedly connected to the outer side of the mounting base 1. Fixed frames 10 are fixedly connected to the top two sides of the connecting seat 11. The top of the fixed frames 10 is threaded... A threaded rod 7 is attached, with a fixing ring 8 rotatably connected to the upper outer end of the threaded rod 7. A connecting plate 9 is fixedly connected to the outer side of the fixing ring 8, and a backrest rail 5 is fixedly connected to one side of the connecting plate 9. A sponge sleeve is fitted on the outer side of the backrest rail 5. An adjusting rotating block 6 is fixedly connected to the top of the threaded rod 7. A complete bar stool can be formed by the mounting base and the bottom structure. By rotating the adjusting rotating block, the threaded rod is driven to rotate on the fixed frame, and the threaded rod moves up and down, thereby driving the fixing ring to move, so that the connecting plate and the backrest rail move up and down, which facilitates operation and improves the practicality of the chair, while also improving the comfort of the person sitting on it. The first fastening collar is located between the second fastening collar to reinforce the support frame, improving the stability of the support frame. The anti-slip pad increases the contact area between the lower end of the support frame and the ground, improving the overall stability of the chair.

[0029] It should be noted that a seat cover 3 is fitted on the outer side of the mounting base 1, and an elastic rope 2 is threaded through the lower outer side of the seat cover 3. The elastic rope 2 is fitted on the outer side of the mounting base 1. The seat cover 3 protects the mounting base 1 and extends its service life. At the same time, the seat cover 3 increases the comfort of people when sitting. The elastic rope 2 limits the position of the seat cover 3.

[0030] A first fastening collar 12 and a second fastening collar 14 are fixedly connected between the four support frames 13. The first fastening collar 12 is located at the upper end of the second fastening collar 14. The first fastening collar 12 is located at the second fastening collar 14 to reinforce the support frames 13 and improve the stability of the support frames 13.

[0031] Furthermore, an anti-slip pad 15 is fixedly connected to the bottom of the support frame 13. The anti-slip pad 15 increases the contact area between the lower end of the support frame 13 and the ground, thereby improving the overall stability of the chair.

[0032] It should be noted that an anti-slip pad is fixedly connected to the bottom of the anti-slip pad seat 15, which further improves the stability of the support frame 13 when supported. A guardrail 4 is fixedly connected to one side of the fixed frame 10 corresponding to the mounting base 1. The guardrail 4 facilitates the stability of people sitting on it, and at the same time provides a certain degree of protection to people, reducing the risk of falling. The guardrail 4 is ring-shaped.

[0033] It should also be noted that the outer side of the guardrail 4 is covered with a rubber sleeve, and one end of the guardrail 4 is rounded. The rubber sleeve improves the comfort when holding the guardrail 4, and the rounded corner of the guardrail 4 reduces the injury caused by limb contact.

[0034] Furthermore, an adjusting rotating block 6 is fixedly connected to the top of the threaded rod 7, which facilitates the rotation of the threaded rod 7 and makes it easier for personnel to operate.

[0035] Additionally, the specific implementation method is as follows: A person sits on the mounting base 1 and adjusts the backrest according to their height. Rotating the adjusting block 6 causes the threaded rod 7 to rotate on the fixed frame 10. The threaded rod 7 moves up and down, thereby moving the fixed ring 8, which in turn moves the connecting plate 9 and the leaning railing 5 up and down. This facilitates operation, improves the chair's practicality, and enhances the comfort of the person sitting on it. The seat cover 3 protects the mounting base 1, extending its service life and increasing the comfort of the person sitting on it. The elastic rope 2 limits the seat cover 3. The first fastening ring 12 reinforces the support frame 13 between the second fastening ring 14, improving the stability of the support frame 13. The anti-slip pad 15 increases the contact area between the lower end of the support frame 13 and the ground, improving the overall stability of the chair and forming a relatively stable, height-adjustable bar stool.

[0036] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
