[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] A reinforced plastic stool, such as Figure 1 - Figure 6 As shown, the stool includes a stool body, which comprises a stool surface 1 and four stool legs 2 for support. The stool surface 1 is made of plastic, and four stool legs 2 are disposed on the outer circular wall of the stool surface 1, equidistantly spaced on the outer wall of the stool surface 1. The stool surface 1 and the four stool legs 2 are injection molded as a single unit. A through hole 12 is provided at the top of the stool surface 1. The through hole 12 is a through hole. After the plastic stool is injection molded in the mold, it will adhere tightly to the core of the mold when it cools and shrinks. At this time, air can enter between the stool surface 1 and the mold in the stool body through the through hole 12, balancing the internal and external air pressure and eliminating vacuum suction, so that the molded plastic stool can be smoothly ejected from the mold. A protective component is provided inside the through hole 12. The components can be assembled inside the stool legs 2 later to avoid the problem of the rough surface inside the stool legs 2 causing scratches to the user's hands during later use of the plastic stool. The outer wall of the stool legs 2 is provided with side reinforcing ribs 3. The side reinforcing ribs 3, the stool surface 1, and the stool legs 2 are all injection molded as one piece. A bottom reinforcing rib 4 is provided between every two stool legs 2. The four bottom reinforcing ribs 4, the stool surface 1, the stool legs 2, and the side reinforcing ribs 3 are all injection molded as one piece. A support component for reinforcing the stool body is provided between the four bottom reinforcing ribs 4. The support component can strengthen the stool body between the four bottom reinforcing ribs 4, and at the same time, it can be convenient for users to temporarily place sundries. It can also be directly disassembled when not in use, making it convenient to use.

[0025] Furthermore, the protective component includes a protective ring 13, which is disposed inside the perforation 12. The protective ring 13 has a circular structure, and the outer circular wall of the protective ring 13 has the same diameter as the inner circular wall of the perforation 12. The outer wall of the protective ring 13 fits against the inner wall of the perforation 12. Two connecting blocks 14 are symmetrically fixedly installed on the outer circular wall of the protective ring 13. The connecting blocks 14 are arc-shaped blocks. Two connecting grooves 15 are formed on the inner circular wall of the perforation 12. The connecting grooves 15 are L-shaped grooves. The connecting blocks 14 can slide into the interior of the connecting grooves 15 and slide inside the connecting grooves 15. Two connecting grooves 16 are formed on the inner circular wall of the stool leg 2. The connecting grooves 16 are inverted L-shaped grooves. The interior of the connecting grooves 16 communicates with the interior of the connecting grooves 15. The connecting blocks 14 can slide into the interior of the connecting grooves 16 and slide inside the connecting grooves 16. With the protective components in place, after the protective ring 13 is installed inside the perforation 12, it is first pressed down to fit against the bottom of the inner wall of the connecting groove 15. Then, the protective ring 13 is rotated counterclockwise. When the connecting block 14 on the protective ring 13 rotates to the corresponding connecting groove 16, the protective ring 13 is pulled up until the connecting block 14 enters the connecting groove 16. Then, the protective ring 13 is rotated counterclockwise again, and the connecting block 14 slides into the connecting groove 16. At this time, the protective ring 13 can be installed inside the perforation 12, which facilitates the assembly of the protective ring 13 after the stool body is injection molded. At the same time, if the stool body breaks, the protective ring 13 can be removed from the perforation 12 and reused. In addition, the protective ring 13 set inside the perforation 12 can protect the user's fingers when they are inserted into the perforation 12, avoiding the problem of fingers directly contacting the rough surface of the inner wall of the perforation 12 and causing hand injuries.

[0026] Furthermore, the support assembly includes a second reinforcing plate 6, which is positioned between two opposing bottom reinforcing ribs 4. The second reinforcing plate 6 is elastic and has a positioning groove 61 on its top. A third reinforcing plate 5 is positioned between the two opposing bottom reinforcing ribs 4, fitting snugly against the inner wall of the positioning groove 61. The tops of the first reinforcing plate 5 and the second reinforcing plate 6 are on the same horizontal plane. Both the first reinforcing plate 5 and the second reinforcing plate 6 have retaining grooves 51 on their inner walls that contact the bottom reinforcing ribs 4. The two opposing reinforcing plates 5 and 6 are individually injection molded and then assembled onto the stool body. When the reinforcing plate 1 (5) and reinforcing plate 2 (6) are pressed down from the top of the two opposing bottom reinforcing ribs 4, the bottom reinforcing ribs 4 can be inserted into the locking grooves 51. The bottom reinforcing ribs 4 and the locking grooves 51 cooperate to limit and fix the reinforcing plate 1 (5) and reinforcing plate 2 (6). With the support components provided, the reinforcing plate 1 (5) and reinforcing plate 2 (6) can be detachably installed between the four bottom reinforcing ribs 4. The four bottom reinforcing ribs 4 can be supported by the cross-shaped structure formed by the reinforcing plate 1 (5) and reinforcing plate 2 (6), reducing the possibility of deformation of the stool legs 2 due to excessive force when the plastic stool is in use. At the same time, the reinforcing plate 1 (5) and reinforcing plate 2 (6) can be used by users to temporarily place sundries, making the use of the plastic stool more convenient.

[0027] The working principle of this utility model is as follows: After the stool surface 1, stool legs 2, side reinforcing ribs 3 and bottom reinforcing ribs 4 are integrally molded by injection molding, the protective ring 13, reinforcing plate surface one 5 and reinforcing plate surface two 6 are assembled with the stool body;

[0028] When assembling the protective ring 13: After the protective ring 13 is installed inside the perforation 12, it is first pressed down to fit against the bottom of the inner wall of the connecting groove 15. Then, the protective ring 13 is rotated counterclockwise. When the connecting block 14 on the protective ring 13 rotates to the corresponding connecting groove 16, the protective ring 13 is pulled up until the connecting block 14 enters the connecting groove 16. Then, the protective ring 13 is rotated counterclockwise again, and the connecting block 14 slides into the connecting groove 16. At this time, the protective ring 13 can be installed inside the perforation 12. After the stool breaks, the protective ring 13 can be removed from the perforation 12 and reused. At the same time, the protective ring 13 can protect the user's fingers when they are inserted into the perforation 12.

[0029] When assembling the reinforcing plate 1 5 and the reinforcing plate 2 6, place them between the four bottom reinforcing ribs 4 in the correct assembly sequence. First, place the reinforcing plate 2 6 between two opposing bottom reinforcing ribs 4. After the bottom reinforcing ribs 4 and the locking grooves 51 fix the reinforcing plate 2 6, place the reinforcing plate 1 5 onto the positioning groove 61 on the top of the reinforcing plate 2 6. The reinforcing plate 1 5 is also fixed by the bottom reinforcing ribs 4 and the locking grooves 51. After fixing, the reinforcing plate 1 5 and the reinforcing plate 2 6 can be supported between the four bottom reinforcing ribs 4. At the same time, the reinforcing plate 1 5 and the reinforcing plate 2 6 can be conveniently used by users to temporarily place miscellaneous items.
