Description

Technical Field

[0001] The utility model relates to the field of bar stools, in particular to a bar stool with an adjustable footrest height. Background Art

[0002] Bar stools are seats designed for bar counters or high tables. They usually have a higher seat height to adapt to the height of the bar counter. Bar stools are not only suitable for bars, but also widely used in many occasions such as homes, restaurants and cafes, increasing the fashion sense and practicality of the space.

[0003] The cam is secured to the bottom of the support frame and is adapted to be moved by the user when the user presses the cam to move the chair, thereby preventing the chair from tipping over.

[0004] The above-mentioned bar stool is not provided with a component for freely adjusting the footrest height. The existing bar stool footrest position cannot be adjusted, so the footrest height cannot be freely adjusted according to different users during use, resulting in poor comfort during use. Therefore, to address the above problem, a bar stool with adjustable footrest height is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology, the existing bar stools are not provided with a component that can freely adjust the footrest height. The position of the footrest of the existing bar stools cannot be adjusted, so that the footrest height cannot be freely adjusted according to different users during use, resulting in poor comfort during use. The utility model proposes a bar stool with adjustable footrest height.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows: the bar stool with adjustable footrest height comprises a base; the top end of the base is fixedly connected to the bottom end of the support frame, the top end of the support frame is fixedly connected to the bottom end of the seat cushion, a footrest body is provided at the rear position outside the support frame, and an adjustment and removal mechanism is directly provided on the support frame and the footrest body;

[0034] Furthermore, one side of the movable plate 19 close to the side end of the movable block 14 is welded to one end of the second rod 20, and the other end of the second rod 20 is inserted into the inner side end of the movable block 14, and the second rod 20 is slidably connected to the movable block 14. The second rod 20 is designed as a round rod.

[0035] During operation, the second threaded rod 17 rotates, driving the outer movable plate 19 to move outward along the outer side of the second threaded rod 17, and at the same time driving the second insertion rod 20 to move outward along the inside of the movable block 14, until the second insertion rod 20 is completely out of the inside of the movable block 14, and the rotation of the rotating block 18 can be stopped.

[0036] Furthermore, guide rods 21 are also provided on the left and right sides of the pedal body 4 near the front end, and the side ends of the pedal body 4 are welded to one end of the guide rod 21. A movable plate 19 is sleeved on the outer side of the guide rod 21, and the guide rod 21 is slidably connected to the movable plate 19. The guide rod 21 is designed as a round rod.

[0037] During operation, the movable plate 19 moves along the outer side of the guide rod 21 while moving.

[0038] Working principle: When the height of the footrest needs to be adjusted, first start the motor 10 at the bottom end of the support frame 2, drive the first threaded rod 11 to rotate, and the top end of the first threaded rod 11 rotates along the inside of the first fixed block 12, so that the first threaded rod 11 drives the moving block 14 to move up and down along the outside of the first threaded rod 11, thereby driving the footrest body 4 to move up and down and adjust. When the appropriate height is reached, stop the motor 10.

[0039] When the second threaded rod 17 is rotated, the outer movable plate 19 is driven to move outward along the outer side of the second threaded rod 17, and the second plugging rod 20 is driven to move outward along the inner side of the movable block 14 until the second plugging rod 20 is completely separated from the inner side of the movable block 14, and the rotation of the rotating block 18 can be stopped. During the movement, the movable plate 19 moves along the outer side of the guide rod 21 at the same time, and then the pedal body 4 is pulled backward, driving the first plugging rod 15 to move outward along the inner side of the rear end of the movable block 14 until the first plugging rod 15 is completely separated from the inner side of the movable block 14, and the pedal body 4 can be removed.
