[0023] The utility model provides a novel star-shaped stable detachable student stool structure, which solves the problems of easy shaking or tilting and great assembly difficulty in the prior art solutions, and achieves the technical effects of simple installation and stable structure.

[0024] See also Figures 1 to 3 A new type of star-shaped stable and detachable student stool structure according to an embodiment of the utility model includes five vertically arranged stool legs 1, and the positions of the five stool legs 1 are distributed in a circle. A first star-shaped connecting and fixing frame 2 and a second star-shaped connecting and fixing frame 3 are arranged in the middle of the circle surrounded by the five stool legs 1. The first star-shaped connecting and fixing frame 2 is located at the upper end of the stool leg 1, and the second star-shaped connecting and fixing frame 3 is located in the middle or lower part of the stool leg 1; in other words, there is a distance between the first star-shaped connecting and fixing frame 2 and the second star-shaped connecting and fixing frame 3, which can make the structure more stable. The first star-shaped connecting and fixing frame 2 and the second star-shaped connecting and fixing frame 3 are both arranged horizontally and have five connectors 4, and the five connectors 4 are installed and connected with the five stool legs 1 one by one. A seat surface 5 is arranged above the first star-shaped connecting and fixing frame 2. Of course, the upper surface of the seat surface 5 is not lower than the upper surface of the stool leg 1, so as to form a stool structure. It can be understood that the seat surface 5 can also be optionally provided with a backrest / armrest, etc. to form other seat forms.

[0025] More specifically, see also Figure 4 The first star-shaped connection fixing frame 2 and / or the second star-shaped connection fixing frame 3 are formed by five racks connected radially (for example, by welding), and the five racks are located in the same horizontal plane, and the outer ends of the racks are connectors 4, so as to form a simple and stable star-shaped structure. In some other optional embodiments, the middle part of the first star-shaped connection fixing frame 2 and / or the second star-shaped connection fixing frame 3 is a ring or a circular plate, and the outer side is a connector 4, which can also achieve the required function.

[0026] The connection between the connector 4 and the stool leg 1 can be selected by plug-in connection, snap-on connection, etc. Preferably, please also refer to Figure 5, the connector 4 is a screw rod head with an external thread, and a through mounting hole is provided on the side of the stool leg 1. The screw rod head passes through the mounting hole and is threadedly connected with a screw cap 6 at the end. More specifically, the size of the screw rod head portion matches the mounting hole, and the size of the screw rod head portion is smaller than the connection between the screw rod head and the first star-shaped connecting bracket 2 / the second star-shaped connecting bracket 3. In other words, the proximal end of the screw rod head has a step on the side facing the distal end. After the screw rod head is inserted, the step can abut against the inner side of the stool leg 1, and the screw cap 6 abuts against the outer side of the stool leg 1, so as to be clamped and fixed after installation. The screw cap 6 can be optionally a nut, and preferably has a structure with a smooth cap body at the end to prevent the end of the screw rod head from being exposed and scratching the human body. This solution adopts an installation method of inserting a threaded rod, which is simple, convenient, safe and reliable.

[0027] The seat surface 5 is detachably connected, and preferably, the seat surface 5 is directly mounted on the first star-shaped connection fixing frame 2. Of course, for this purpose, the first star-shaped connection fixing frame 2 has a structure above that can horizontally support the seat surface 5. This method is simpler to install.

[0028] Further preferably, the seat surface 5 is provided with a mounting groove 7, and at least a part of the upper end of the stool leg 1 is accommodated in the mounting groove 7. For example, the mounting groove 7 is a notch located at the edge of the seat surface 5, and there are five mounting grooves 7 and they correspond to the five stool legs 1 one by one. The seat surface 5 is matched and embedded between the five stool legs 1, and fits on the side. More specifically, the stool leg 1 is cylindrical, and the mounting groove 7 is a semi-circular arc concave surface. After installation (for example, after the screw cap 6 is tightened), the stool leg 1 is clamped and positioned in the mounting groove 7, and the seat surface 5 is clamped and positioned in the middle of the five stool legs 1; the upper surface of the stool leg 1 is flush with the upper surface of the seat surface 5. This method further fixes the seat surface 5 and increases the integrity after installation. In some optional embodiments, the mounting groove 7 and the corresponding side of the stool leg 1 are provided with magnets or plug-in or buckle parts, so as to achieve detachable connection.

[0029] See also Figure 4 In the preferred embodiment, the positions of the five stool legs 1 are distributed on the same horizontal circumference and are evenly distributed in the circumferential direction. Accordingly, the connectors 4 of the first star-shaped connecting bracket 2 and the second star-shaped connecting bracket 3 are distributed in a regular pentagonal shape, which makes the structure more regular and the force more even. In addition, the stool legs 1 are cylindrical and the seat surface 5 is disc-shaped. The overall structure is smooth, harmonious and beautiful, and has no edges and corners, which reduces the risk of bumping and damaging the human body.

[0030] In summary, the new star-shaped stable and detachable student stool structure of the utility model is mainly composed of a seat surface 5, a stool foot 1 and a star-shaped connecting and fixing frame. The cylindrical stool foot 1 cooperates with the semicircular concave surface of the seat surface 5, and the star-shaped connecting and fixing frame passes through the installation hole of the stool foot 1. After the screw rod head passes through, it is fixed and tightened with the screw cap 6, so that the five stool feet 1 are clamped inwardly to generate physical friction, so as to achieve the effect of stably clamping the seat surface 5. Using the physical principle of five-point stability, the upper and lower star-shaped connecting and fixing frames and the stool foot 1 form a stable overall structure of the stool foot. The biggest difference between the structure of this scheme and the structure of the traditional stool is that the stool foot and the seat surface are innovatively connected and fixed by a star-shaped connecting and fixing frame. Using the physical triangular stability law, the structure and installation are simple, easy to operate, and the overall structure is stable. There will be no shaking or tilting of the seat surface after long-term use, which helps to avoid bad sitting posture. It is especially suitable for students to attend meetings and other situations. At the same time, due to the simple and lightweight structure, it is easy to carry and move flexibly.
