Description
Technical Field
[0001] The utility model relates to the technical field of furniture, in particular to an adjustable high stool. Background Art
[0002] A high stool is a piece of furniture, usually consisting of a seat, legs, and support. Because the legs are long, the sight and height of the person sitting on it will be improved. High stools are widely used. The most common use is as a bar counter in a bar, which is convenient for guests to sit and taste wine or chat. In addition, high stools can also be used in company tea rooms, home bars and other places, providing a higher perspective and a comfortable sitting posture.
[0003] The high stools on the market usually consist of a pneumatic cylinder, a button, and a handle under the seat. When you need to adjust the height, sit on the stool and pull the handle up or down until you reach the desired height. The handle releases or increases the compressed gas to adjust the seat height; however, if the pneumatic cylinder or related components are improperly designed or manufactured, or improperly maintained, there may be some potential hazards. For example, if the seal inside the pneumatic cylinder is not tight, it may cause gas leakage, affecting the adjustment effect, and may even cause safety hazards. In addition, if the material of the pneumatic cylinder does not meet the standards, fatigue fracture may occur after long-term use, causing the chair to suddenly drop or tilt, and the user may be injured. Therefore, it is necessary to provide an adjustable high stool to solve the above technical problems. Utility Model Content

[0027] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Reference Figure 1-4 The utility model provides an embodiment of an adjustable high stool, comprising a base 1, wherein universal wheels 9 are installed around the bottom end of the base 1. Installing the universal wheels 9 will make the high stool more convenient. The top of the base 1 is fixedly connected with a connecting seat 3, and the top of the connecting seat 3 is fixedly connected with a slide sleeve 2. A footrest 6 is fixedly installed in the middle of the slide sleeve 2. The footrest 6 is installed around the slide sleeve 2 to support the user's feet, allowing the user to relax his feet when sitting, thereby increasing the comfort of use. A sliding component is fixedly installed on the outer side of the slide sleeve 2, and a rotating rod 12 is threadedly connected to the top of the slide sleeve 2. The top of the rotating rod 12 is rotatably connected to a mounting seat 5, and a worm 10 is rotatably connected inside the mounting seat 5. One end of the rotating rod 12 is fixedly connected to a worm gear 11, and the worm gear 11 is meshed with the worm 10. A rotating groove 14 is provided on the bottom side of one end of the worm 10, and a connecting rod 13 is rotatably connected inside the rotating groove 14. The end of the connecting rod 13 away from the worm 10 is fixedly connected with a handle 7.
[0029] Specifically, the connecting seat 3 has a stabilizing function, which fixes the tightness between the base 1 and the slide sleeve 2. The top of the rotating rod 12 is rotatably connected to the mounting seat 5. The top of the mounting seat 5 is fixedly connected to a cushion 8. The cushion 8 is round in shape and made of sponge material to increase comfort. The worm 10 drives the worm wheel 11 to rotate. The worm wheel 11 is connected to the rotating rod 12 and rotates on the middle thread of the slide sleeve 2 to achieve adjustability. The handle 7 is pulled outward under force, and the seat height can be adjusted by rotating the handle 7. The handle 7 is forced inward and is rotated into the rotating groove 14 for better storage and to avoid collision with people's legs.
[0030] The sliding assembly includes a vertical rod 4 , which is mounted on the outer wall of the slide sleeve 2 . A sliding rod 16 is slidably connected to one side of the vertical rod 4 , and the top end of the sliding rod 16 is fixedly connected to the bottom end of the mounting seat 5 .
[0031] Specifically, the sliding rod 16 is slidably connected to the inner wall of the vertical rod 4 and moves up and down. The vertical rod 4 is fixedly installed on the outer wall of the slide sleeve 2. When the sliding rod 16 moves up and down, the sliding assembly is fixed. A sliding groove 15 that slidably cooperates with the sliding rod 16 is opened on one side of the vertical rod 4. A protrusion 17 that slidably cooperates with the vertical rod 4 is opened on one side of the sliding rod 16. The sliding rod 16 slides up and down on the inner wall of the vertical rod 4 through the sliding groove 15 and the protrusion 17.
[0032] Working principle: pull the handle 7 under the seat cushion 8 outward with force, turn the handle 7, and the end away from the handle 7 is connected with a worm 10, which drives the worm wheel 11 to rotate in meshing, and a rotating rod 12 is connected in the middle of the worm wheel 11. The rotating rod 12 slides inside the slide sleeve 2 to achieve up and down movement. The outer wall of the slide sleeve 2 is fixedly installed with a vertical rod 4, and the vertical rod 4 is slidably connected to the sliding rod 16 through a sliding groove 15 and a protrusion 17. The sliding rod 16 is rotatably connected to the mounting seat 5, and the mounting seat 5 is internally rotatably connected with the worm 10. Therefore, when the rotating rod 12 moves up and down inside the slide sleeve 2, the vertical rod 4 cooperates with the sliding rod 16 to slide up and down; when the handle 7 is not in use, it is forced inward and pushed into the rotating groove 14 to achieve better storage and avoid collision with people's legs.
[0033] The footrest 6 is installed around the slide sleeve 2 to support the user's feet, allowing the user to relax his feet when sitting, thereby increasing the comfort of use. The cushion 8 fixed on the top of the mounting seat 5 is round in shape and made of sponge material to increase comfort. Four universal wheels 9 are installed at the bottom of the base 1 to make the high stool more convenient.
