Description

Technical Field

[0001] This utility model relates to the field of bar stool technology, and in particular to a device for enhancing the structural stability of bar stools. Background Technology

[0002] Bar stools, as common furniture, are widely used in bars, home bars, cafes, and other settings. Existing bar stools typically consist of a seat, legs, and footrest. The legs are often a single upright or a three- or four-legged distributed support structure. In actual use, when the user's posture shifts, when they stand up unevenly, or when subjected to external impact, single-upright legs are prone to wobbling, while distributed legs may experience decreased stability due to loose connections, posing a risk of tipping over. This instability is particularly pronounced for taller or heavier users.

[0003] Currently, while some bar stools improve stability by increasing the diameter or number of legs, this leads to an increase in overall weight and production costs, and makes them difficult to adapt to existing bar stools for modification and upgrading, resulting in poor applicability. Therefore, there is a need to propose a device to enhance the structural stability of bar stools. Utility Model Content

[0020] Example

[0021] like Figures 1 to 4As shown, this utility model proposes a device to enhance the structural stability of a bar stool, including a seat 1. A support rod 2 is provided on the bottom surface of the seat 1, and the bottom surface of the seat 1 is fixedly connected to the top surface of the support rod 2. Multiple telescopic rods 3 are rotatably arranged on the outer ring of the bottom end of the support rod 2. The top end of each telescopic rod 3 is rotatably connected to the bottom surface of the seat 1. A spring 4 is sleeved on the outer ring of each telescopic rod 3. The telescopic rods 3 can guide and limit the elastic recovery ability of the springs 4. The cooperation between the telescopic rods 3 and the springs 4 can disperse the force generated by the seat 1, improving the support. The support rod 2 has a threaded rod 5 on its bottom surface, and the bottom surface of the support rod 2 is fixedly connected to the top of the threaded rod 5. The outer ring of the threaded rod 5 is threadedly connected to a knob 6. The bottom surface of the knob 6 is rotatably connected to a connecting rod 7. The bottom surface of the knob 6 has an L-shaped ring 17, and the bottom surface of the knob 6 is fixedly connected to the top surface of the L-shaped ring 17. The top surface of the connecting rod 7 has an L-shaped ring groove, and the L-shaped ring 17 is rotatably connected to the L-shaped ring groove. The L-shaped ring groove can guide and limit the movement of the knob 6, thereby preventing the knob 6 from separating from the connecting rod 7.

[0022] The connecting rod 7 has a rectangular groove inside, and the threaded rod 5 is located inside the rectangular groove. A rectangular block 18 is provided at the bottom end of the threaded rod 5. The bottom end of the threaded rod 5 is fixedly connected to the top surface of the rectangular block 18, and the rectangular block 18 is slidably connected to the rectangular groove. The rectangular groove can guide and limit the rectangular block 18, so that the rectangular block 18 always maintains a straight running state, thereby guiding and limiting the running trajectory of the threaded rod 5, so that the threaded rod 5 always maintains a straight running state. When the knob 6 is rotated, the threaded rod 5 can be moved up and down. The connecting rod 7 has a moving groove 8 on its rear side. Multiple positioning grooves 9 are provided on both the left and right sides of the moving groove 8. The positioning grooves 9 on the left and right sides are symmetrically arranged. A moving frame 10 is slidably arranged on the outside of the connecting rod 7. A pressing groove is provided on both the left and right sides of the moving frame 10. A telescopic rod 11 is provided on the side of the two pressing grooves that are close to each other. The telescopic rod 11 is fixedly installed inside the pressing groove. A spring 12 is sleeved on the outer ring of each telescopic rod 11. The spring 12 can be guided and limited by the telescopic rod 11.

[0023] Each of the two telescopic rods 11 has an adjustment button 13 at one end that is far apart from each other. The telescopic rod 11 is fixedly connected to the adjustment button 13, and the adjustment button 13 is slidably connected to the pressing groove to facilitate the operation of the adjustment button 13. Each adjustment button 13 has a positioning block 14 on its front side, and the adjustment button 13 is fixedly connected to the positioning block 14. Each positioning block 14 is slidably connected to the corresponding positioning groove 9 to facilitate the positioning of the moving frame 10. A foot pedal 15 is provided on the front side of the telescopic rod 11, and the front side of the telescopic rod 11 is fixedly connected to the rear side of the foot pedal 15. A chair support 16 is provided at the bottom end of the connecting rod 7, and the bottom end of the connecting rod 7 is fixedly connected to the top surface of the chair support 16.

[0024] In this embodiment, when using this device, the force generated by the seat 1 and support rod 2 is distributed by the telescopic rod 3 and spring 4, which increases the support force while distributing the force. When the height of the seat 1 needs to be adjusted, the knob 6 can be turned. The rotation of the knob 6 can drive the threaded rod 5 to move up and down in the inner circle of the knob 6, thereby adjusting the height of the seat 1 to a suitable height. When the height of the foot pedal 15 needs to be adjusted, the two adjustment buttons 13 can be pressed towards each other. The movement of the adjustment buttons 13 can drive the corresponding positioning block 14 to be pulled out from the inside of the corresponding positioning groove 9, thereby driving the entire moving frame 10 to move up and down in the outer circle of the connecting rod 7. Then, the force on the adjustment button 13 is released, and the adjustment button 13 can be pushed back to its original position by the telescopic rod 11 and spring 12, thereby driving the corresponding positioning block 14 to be installed into the inside of the corresponding positioning groove 9, thus ensuring the stability of the moving frame 10, and thus adjusting the foot pedal 15 to a suitable position.

[0025] The above-described specific embodiments are merely preferred embodiments of the present invention.
